"Wealth is judged according to the life style one has.",
"Inheritance builds an important part in one's wealth.",
"High income may make one live high and get rich t the same time.",
"Wealth is more of what one has made than anything else."
] | Which of the following statements is true? | What most people don't realize is that wealth isn't the same as income. If you make $ 1 million a year and spend $ 1 million, you're not getting wealthier, you're just living high. Wealth is what you accumulate, not what you spend.
The most successful accumulators of wealth spend far less than they can afford on houses, cars, vacations and entertainment. Why? Because these things offer little or no return. The wealthy would rather put their money into investments or their businesses. It's an attitude.
Millionaires understand that when you buy a luxury house, you buy a luxury life -style too. Your property taxes skyrocket, along with the cost of utilities and insurance, and the prices of nearby services, such as grocery stores, tend to be higher.
The rich man's attitude can also be seen in his car. Many drive old unpretentious sedans. Sam Walton, billionaire founder of the Wal - Mart Store, Inc., drove a pickup truck.
Most millionaires measure success by net worth, not income. Instead of taking their money home, they plow as much as they can into their businesses, stock portfolios and other assets. Why? Because the government doesn't tax wealth; it taxes income you bring home for consumption, the more the government taxes.
The person who piles up net worth fastest tends to put every dollar he can into investments, not consumption. All the while, of course, he's reinvesting his earnings from investments and watching his net worth soar. That's the attitude as well.
The best wealth-builders pay careful attention to their money and seek professional advice. Those who spend heavily on cars, boats and buses, I've found, tend to skimp on investment advice. Those who skimp on the luxuries are usually more willing to pay top dollar for good legal and financial advice.
The self-made rich develop clear goals for their money. They may wish to retire early, or they may want to leave an estate to their children. The goals vary, but two things are consistent: they have a dollar figure in mind-the amount they want to save by age 50, perhaps - and they work unceasingly toward that goal.
One thing may surprise you. If you make wealth - not just income - your goal, the luxury house you've been dreaming about won't seem so alluring. You'll have the attitude. | 1788.txt | 3 |

] | The picture of the reading ability of the American people, drawn by the author, is ________. | It is hardly necessary for me to cite all the evidence of the depressing state of literacy. These figures from the Department of Education are sufficient: 27 million Americans cannot read at all, and a further 35 million read at a level that is less than sufficient to survive in our society.
but my own worry today is less that of the overwhelming problem of elemental literacy than it is of the slightly more luxurious problem of the decline in the skill even of the middle-class reader, of his unwillingness to afford those spaces of silence, those luxuries of domesticity and time and concentration, that surround the image of the classic act of reading. It has been suggested that almost 80 percent of America's literate, educated teenagers can no longer read without an accompanying noise (music) in the background or a television screen flickering at the corner of their field of perception. We know very little about the brain and how it deals with simultaneous conflicting input, but every common-sense intuition suggests we should be profoundly alarmed. This violation of concentration, silence, solitude goes to the very heart of our notion of literacy; this new form of part-reading, of part-perception against background distraction, renders impossible certain essential acts of apprehension and concentration, let alone that most important tribute any human being can pay to a poem or a piece of prose he or she really loves, which is to learn it by heart. Not by brain, by heart; the expression is vital.
Under these circumstances, the question of what future there is for the arts of reading is a real one. Ahead of us lie technical, psychic , and social transformations probably much more dramatic than those brought about by Gutenberg, the German inventor in printing. The Gutenberg revolution, as we now know it, took a long time; its effects are still being debated. The information revolution will touch every fact of composition, publication, distribution, and reading.

] | How much money does an American earning $40,000 per year pay to the federal government as income tax? | Americans often say that there are only two things a person can be sure of in life: death and taxes. Many people feel that the United States has the worst taxes in the world.
Taxes are the money that people pay to support their government. There are generally three levels of government in the United States; federal, state and city; therefore,there are three types of taxes.
Salaried people who earn more than four to five thousand dollars per year must pay a certain part of their salaries to the federal government. The percentage varies for different people. It depends on their salaries. The federal government has a two?level income tax; that is, 15 or 28 percent. $17,850 is the cut?off. The tax rate is 15 percent below $17,850 and 28 percent above.
The second tax is for the state government: New York, California, or any of the other forty?eight states; Some states have an income tax similar to that of the federal government. Of course,the percentage for the state tax is lower. Other states have a sales tax, which is a percentage charged to any item which people buy in the state. Some states use income tax and sales tax to raise their revenues.
The third tax is for the city. This tax comes in two forms: property tax (residents who own a home have to pay taxes on it) and excise tax,which is collected on vehicles in a city. The cities use this money for education,police,public works, etc.
Since Americans pay such high taxes, they often feel that they are working one day each week just to pay their taxes. People always complain about taxes. They often say that the government misuses their tax dollars. They all believe that taxes are too high in this country. | 2658.txt | 0 |

It is present in the body in a very small amount but makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work.
Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys formerly with the United States Air Force noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate.
The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein foods such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these food.

] | Researchers have come to believe that dreams . | Of all the components of a good night's sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just "mental noise" -- the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind's emotional thermostat, regulating moods while the brain is "off-line." And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better, "It's your dream," says Rosalind Cartwright, chair of psychology at Chicago's Medical Center. "If you don't like it, change it."
Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleep -- when most vivid dreams occur -- as it is when fully awake, says Dr, Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the "emotional brain") is especially active, while the prefrontal cortex (the center of intellect and reasoning) is relatively quiet. "We wake up from dreams happy or depressed, and those feelings can stay with us all day." says Stanford sleep researcher Dr. William Dement.
The link between dreams and emotions shows up among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events -- until, it appears, we begin to dream.
And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.
At the end of the day, there's probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "we wake up in a panic," Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people's anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep -- or rather dream -- on it and you'll feel better in the morning. | 3093.txt | 0 |

] | What can we learn about Cisco from the passage? | Yet with economies in free fail, managers also need up-to-date information about what is happening to their businesses, so that they can change course rapidly if necessary. Cisco, an American network-equipment giant, has invested over many years in the technology needed to generate such data .Frank Caideroni, the firm's CFO, says that every day its senior executives can track exactly what orders are coming in from sales teams around the world, and identify emerging trends in each region and market segment. And at the end of each month, the firm can get reliable financial results within four hours of closing its books. Most firms have to wait days or even weeks for such certainty.
Admittedly, Cisco's financial results have not made happy reading recently because, in common with many other large technology companies, it has seen demand for its products decline in the downturn. In early February it announced that its fiscal second-quarter revenues of $ 9.1 billion were 7.5% lower than the same period in 2008 and that its profit had fallen by 27%, to $1.5 billion.
In response to hard times, Cisco plans to cut $1 billion of costs this year by, among other things, making use of its own video-conferencing and other communications technologies to reduce the amount its executives travel. It is also using these facilities to relay information from employees on the ground to its senior managers, and to get instructions from Cisco's leaders back out to its 67,000 staff. A rapid exchange of information and instructions is especially valuable if the company wants to alter course in stormy times.
If everybody in a company can rapidly grasp what they have to do and how it is changing, they are more likely to get the job done. But some firms are reluctant to share their goals with the wider world. Unilever, a big Anglo-Dutch consumer-goods group, has decided against issuing a 2009 financial forecast to investors, arguing that it is difficult to predict what is going to happen, given the dangerous state of the world economy. "We're not just going to provide numbers for the sake of it," explains James Allison, the company's head of investor relations. Other companies that have decided not to provide annual earnings estimates for 2009 include Costco, a big American retailer, and Union Pacific, an American railway company.
Some firms, such as Intel, seem to have chosen to take things quarter by quarter. The giant chipmaker said in January that it would not issue an official forecast for the first quarter of 2009 after its fourth-quarter 2008 profit decreased by 90%. Several retail chains have also stopped providing monthly sales estimates because they cannot see what the future holds.

And at the end of each month, the firm can get reliable financial results within four hours of closing its books. Most firms have to wait days or even weeks for such certainty.
Admittedly, Cisco's financial results have not made happy reading recently because, in common with many other large technology companies, it has seen demand for its products decline in the downturn. In early February it announced that its fiscal second-quarter revenues of $ 9.1 billion were 7.5% lower than the same period in 2008 and that its profit had fallen by 27%, to $1.5 billion.
In response to hard times, Cisco plans to cut $1 billion of costs this year by, among other things, making use of its own video-conferencing and other communications technologies to reduce the amount its executives travel. It is also using these facilities to relay information from employees on the ground to its senior managers, and to get instructions from Cisco's leaders back out to its 67,000 staff. A rapid exchange of information and instructions is especially valuable if the company wants to alter course in stormy times.
If everybody in a company can rapidly grasp what they have to do and how it is changing, they are more likely to get the job done. But some firms are reluctant to share their goals with the wider world. Unilever, a big Anglo-Dutch consumer-goods group, has decided against issuing a 2009 financial forecast to investors, arguing that it is difficult to predict what is going to happen, given the dangerous state of the world economy. "We're not just going to provide numbers for the sake of it," explains James Allison, the company's head of investor relations. Other companies that have decided not to provide annual earnings estimates for 2009 include Costco, a big American retailer, and Union Pacific, an American railway company.
Some firms, such as Intel, seem to have chosen to take things quarter by quarter. The giant chipmaker said in January that it would not issue an official forecast for the first quarter of 2009 after its fourth-quarter 2008 profit decreased by 90%. Several retail chains have also stopped providing monthly sales estimates because they cannot see what the future holds. Retailers, chipmakers and firms in many other industries may have a long wait before the economic fog finally lifts. | 891.txt | 3 |

"The greatest victory for a man is to conquer everything except himself.",

] | What does the reader learn from the first paragraph? | "The first and best of victories is for a man to conquer himself; to be conquered by himself is, of all things, the most shameful," says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses and feelings, and from that moment he gives up his moral freedom.
A single angry word has lost many a friend. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. "Whom the gods would destroy they first make mad." "Keep cool", says George Herbert, "for fierceness makes error a fault."
To be angry with a weak man is to prove that you are not strong yourself. "Anger," says Pythagoras, "brings with folly and ends with regret." You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Self-control is man's last greatest victory.
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking also. | 2892.txt | 1 |

"matched to six to seven million structures called cones.",

"signaled by about 120 million rods in the eye."
] | Visual illusions often take place when the image of reality is _ . | You stare at waterfall for a minute or two, and then shift your gaze to its surroundings. What you now see appears to drift upward.
These optical illusions occur because the brain is constantly matching its model of reality to signals from the body's sensors and interpreting what must be happening-that your brain must have moved, not the other; that downward motions is now normal, so a change from it must now be perceived as upward motion.
The sensors that make this magic are of two kinds. Each eye contains about 120 million rods, which provide somewhat blurry black and white vision. These are the windows of night vision; once adapted to the dark, they can detect a candle burning ten miles away.
Color vision in each eye comes from six to seven million structures called cones. Under ideal conditions, every cone can "see" the entire rainbow spectrum of visible colors, but one type of cone is most sensitive to red, another to green, a third to blue.
Rods and cones send their messages pulsing an average 20 to 25 times per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photographs are projected onto screens at 24 frames per second, tricking our eyes into seeing a continuous moving picture.
Like apparent motion, color vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called "the violet hour." A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of blue and green, and they impart a strange vividness to the garden's blue flowers.
However, look at a white shirt during the reddish light of sunset, and you'll still see it in its "true" color-white, not red. Our eyes are constantly comparing an object against its surroundings. They therefore observe the effect of a shift in the color of illuminating on both, and adjust accordingly.
The eyes can distinguish several million graduations of light and shade of color. Each waking second they flash tens of millions of pieces of information to the brain, which weaves them incessantly into a picture of the world around us.
Yet all this is done at the back of each eye by a fabric of sensors, called the retina, about as wide and as thick as a postage stamp.

Symbolic of national unity as they claim to be, their very history-and sometimes the way they behave today-embodies outdated and indefensible privileges and inequalities. At a time when Thomas Piketty and other economists are warming of rising inequality and the increasing power of inherited wealth, it is bizarre that wealthy aristocratic families should still be the symbolic heart of modern democratic states.
The most successful monarchies strive to abandon or hide their old aristocratic ways. Princes and princesses have day-jobs and ride bicycles, not horses (or helicopters). Even so, these are wealthy families who party with the international 1%, and media intrusiveness makes it increasingly difficult to maintain the right image.
While Europes monarchies will no doubt be smart enough to survive for some time to come, it is the British royals who have most to fear from the Spanish example.
It is only the Queen who has preserved the monarchys reputation with her rather ordinary (if well-heeled) granny style. The danger will come with Charles, who has both an expensive taste of lifestyle and a pretty hierarchical view of the world. He has failed to understand that monarchies have largely survived because they provide a service-as non-controversial and non-political heads of state. Charles ought to know that as English history shows, it is kings, not republicans, who are the monarchys worst enemies. | 3203.txt | 3 |

This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming, and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.
I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream-colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood, I felt that this was a gift that my father would truly appreciate.
Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift. | 3731.txt | 2 |

There's work to be done, but workers aren't ready to do it-they're in the wrong places, or they have the wrong skills, Our problems are"structural,"and will take many years to solve.
But don't bother asking for evidence that justifies this bleak view. There isn't any. On the contrary, all the facts suggest that high unemployment in America is the result of inadequate demand. saying that there're no easy answers sounds wise. But it's actually foolish: our unemployment crisis could be cured very quickly if we had the intellectual clarity and political will to act. In other words, structural unemployment is a fake problem, which mainly serves as an excuse for not pursing real solutions.
The fact is job openings have plunged in every major sector, while the number of workers forced into part-time employment in almost all industries has soared. Unemployment has surged in every major occupational category. Only three states. With a combined population not much larger than that of Brooklyn, have unemployment rates below 5%. So the evidence contradicts the claim that we're mainly suffering from structural unemployment. Why, then, has this claim become so popular?
Part of the answer is that this is what always happens during periods of high unemployment-in part because experts and analysts believe that declaring the problem deeply rooted, with no easy answers, makes them sound serious.
I've been looking at what self-proclaimed experts were saying about unemployment during the Great Depression; it was almost identical to what Very Serious People are saying now. Unemployment cannot be brought down rapidly, declared one 1935 analysis, because the workforce is"unadaptable and untrained. It cannot respond to the opportunities which industry may offer."A few years later, a large defense buildup finally provided a fiscal stimulus adequate to the economy's needs-and suddenly industry was eager to employ those"unadaptable and untrained"workers.
But now, as then, powerful forces are ideologically opposed to the whole idea of government action on a sufficient scale to jump-start the economy. And that, fundamentally, is why claims that we face huge structural problems have been multiplying: they offer a reason to do nothing about the mass unemployment that is crippling out economy and our society.
So what you need to know is that there's no evidence whatsoever to back these claims. We aren't suffering from a shortage of needed skills, We're suffering from a lack of policy resolve.

"Its capacity actually knows no limits.",
"It grows sophisticated with practice.",
"It keeps our most precious memories until life's end.",
"New information learned pushes old information out."
] | What have past behavioural studies found about our brain? | The brain is a seemingly endless library, whose shelves house our most precious memories as well as our lifetime's knowledge. But is there a point where it reaches capacity?
The answer is no, because brains are more sophisticated than that. Instead of just crowding in, old information is sometimes pushed out of the brain for new memories to form.
Previous behavioural studies have shown that learning new information can lead to forgetting. But in a new study, researchers demonstrated for the first time how this effect occurs in the brain.
In daily life, forgetting actually has clear advantages. Imagine, for instance, that you lost your bank card. The new card you receive will come with a new personal identification number (PIN). Each time you remember the new PIN, you gradually forget the old one. This process improves access to relevant information, without old memories interfering.
And most of us may sometimes feel the frustration of having old memories interfere with new, relevant memories. Consider trying to remember where you parked your car in the same car park you were at a week earlier. This type of memory (where you are trying to remember new, but similar information) is particularly vulnerable to interference.
When we acquire new information, the brain automatically tries to incorporate()it within existing information by forming associations. And when we retrieve()information, both the desired and associated but irrelevant information is recalled.
The majority of previous research has focused on how we learn and remember new information. But current studies are beginning to place greater emphasis on the conditions under which we forget, as its importance begins to be more appreciated.
A very small number of people are able to remember almost every detail of their life. While it may sound like an advantage to many, people with this rare condition often find their unusual ability burdensome.
In a sense, forgetting is our brain's way of sorting memories, so the most relevant memories are ready for retrieval. Normal forgetting may even be a safety mechanism to ensure our brain doesn't become too full. | 1006.txt | 3 |

And most of us may sometimes feel the frustration of having old memories interfere with new, relevant memories. Consider trying to remember where you parked your car in the same car park you were at a week earlier. This type of memory (where you are trying to remember new, but similar information) is particularly vulnerable to interference.
When we acquire new information, the brain automatically tries to incorporate()it within existing information by forming associations. And when we retrieve()information, both the desired and associated but irrelevant information is recalled.
The majority of previous research has focused on how we learn and remember new information. But current studies are beginning to place greater emphasis on the conditions under which we forget, as its importance begins to be more appreciated.
A very small number of people are able to remember almost every detail of their life. While it may sound like an advantage to many, people with this rare condition often find their unusual ability burdensome.
In a sense, forgetting is our brain's way of sorting memories, so the most relevant memories are ready for retrieval. Normal forgetting may even be a safety mechanism to ensure our brain doesn't become too full. | 1006.txt | 2 |

"makes foods easily digestible",
"makes foods fat-free while keeping them delicious"
] | We learn from the passage that olestra is a substance that ________. | Imagine eating everything delicious you want-with none of the fat. That would be great, wouldn't it?
New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients and can also cause unpleasant side effects in some people. So it's up to decide whether the new fat-free products taste good enough to keep eating.
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can't be digested at all.
Normally, special chemicals in the intestines "grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatty acids.
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E, and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say it's that ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being absorbed. It can also prevent the absorption of carotenoids , compounds that may reduce the risk of cancer, heart disease, etc.
Manufacturers are adding vitamins A, D, E, and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming. | 3645.txt | 3 |

] | According to paragraph l, parents in Japan tend to think of preschool primarily as a place where children can | Preschools - educational programs for children under the age of five - differ significantly from one country to another according to the views that different societies hold regarding the purpose of early childhood education. For instance, in a cross-country comparison of preschools in China, Japan, and the United States, researchers found that parents in the three countries view the purpose of preschools very differently. Whereas parents in China tend to see preschools primarily as a way of giving children a good start academically, Japanese parents view them primarily as a way of giving children the opportunity to be members of a group. In the United States, in comparison, parents regard the primary purpose of preschools as making children more independent and self-reliant, although obtaining a good academic start and having group experience are also important.
While many programs designed for preschoolers focus primarily on social and emotional factors, some are geared mainly toward promoting cognitive gains and preparing preschoolers for the formal instruction they will experience when they start kindergarten. In the United States, the best-known program designed to promote future academic success is Head Start. Established in the 1960s when the United States declared the War on Poverty, the program has served over 13 million children and their families. The program, which stresses parental involvement, was designed to serve the "whole child", including children's physical health, self-confidence, social responsibility, and social and emotional development.
Whether Head Start is seen as successful or not depends on the lens through which one is looking. If, for instance, the program is expected to provide long-term increases in IQ (intelligence quotient) scores, it is a disappointment. Although graduates of Head Start programs tend to show immediate IQ gains, these increases do not last. On the other hand, it is clear that Head Start is meeting its goal of getting preschoolers ready for school. Preschoolers who participate in Head Start are better prepared for future schooling than those who do not. Furthermore, graduates of Head Start programs have better future school grade. Finally, some research suggests that ultimately Head Start graduates show higher academic performance at the end of high school, although the gains are modest.
In addition, results from other types of preschool readiness programs indicate that those who participate and graduate are less likely to repeat grades, and they are more likely to complete school than readiness program, for every dollar spent on the program, taxpayers saved seven dollars by the time the graduates reached the age of 27.
The most recent comprehensive evaluation of early intervention programs suggests that, taken as a group, preschool programs can provide significant benefits, and that government funds invested early in life may ultimately lead to a reduction in future costs. For instance, compared with children who did not participate in early intervention programs, participants in various programs showed gains in emotional or cognitive development, better educational outcomes, increased economic self-sufficiency, reduced levels of criminal activity, and improved health-related behaviors. Of course, not every program produced all these benefits, and not every child benefited to the same extent. Furthermore, some researchers argue that less-expensive programs are just as good as relatively expensive ones, such as Head Start. Still, the results of the evaluation were promising, suggesting that the potential benefits of early intervention can be substantial.
Not everyone agrees that programs that seek to enhance academic skills during the preschool years are a good thing. In fact, according to developmental psychologist David Elkind, United States society tends to push children so rapidly that they begin to feel stress and pressure at a young age. Elkind argues that academic success is largely dependent upon factors out of parents' control, such as inherited abilities and a child's rate of maturation. Consequently, children of a particular age cannot be expected to master educational material without taking into account their current level of cognitive development. In short, children require development appropriate educational practice, which is education that is based on both typical development and the unique characteristics of a given child. | 3831.txt | 3 |

For instance, in a cross-country comparison of preschools in China, Japan, and the United States, researchers found that parents in the three countries view the purpose of preschools very differently. Whereas parents in China tend to see preschools primarily as a way of giving children a good start academically, Japanese parents view them primarily as a way of giving children the opportunity to be members of a group. In the United States, in comparison, parents regard the primary purpose of preschools as making children more independent and self-reliant, although obtaining a good academic start and having group experience are also important.
While many programs designed for preschoolers focus primarily on social and emotional factors, some are geared mainly toward promoting cognitive gains and preparing preschoolers for the formal instruction they will experience when they start kindergarten. In the United States, the best-known program designed to promote future academic success is Head Start. Established in the 1960s when the United States declared the War on Poverty, the program has served over 13 million children and their families. The program, which stresses parental involvement, was designed to serve the "whole child", including children's physical health, self-confidence, social responsibility, and social and emotional development.
Whether Head Start is seen as successful or not depends on the lens through which one is looking. If, for instance, the program is expected to provide long-term increases in IQ (intelligence quotient) scores, it is a disappointment. Although graduates of Head Start programs tend to show immediate IQ gains, these increases do not last. On the other hand, it is clear that Head Start is meeting its goal of getting preschoolers ready for school. Preschoolers who participate in Head Start are better prepared for future schooling than those who do not. Furthermore, graduates of Head Start programs have better future school grade. Finally, some research suggests that ultimately Head Start graduates show higher academic performance at the end of high school, although the gains are modest.
In addition, results from other types of preschool readiness programs indicate that those who participate and graduate are less likely to repeat grades, and they are more likely to complete school than readiness program, for every dollar spent on the program, taxpayers saved seven dollars by the time the graduates reached the age of 27.
The most recent comprehensive evaluation of early intervention programs suggests that, taken as a group, preschool programs can provide significant benefits, and that government funds invested early in life may ultimately lead to a reduction in future costs. For instance, compared with children who did not participate in early intervention programs, participants in various programs showed gains in emotional or cognitive development, better educational outcomes, increased economic self-sufficiency, reduced levels of criminal activity, and improved health-related behaviors. Of course, not every program produced all these benefits, and not every child benefited to the same extent. Furthermore, some researchers argue that less-expensive programs are just as good as relatively expensive ones, such as Head Start. Still, the results of the evaluation were promising, suggesting that the potential benefits of early intervention can be substantial.
Not everyone agrees that programs that seek to enhance academic skills during the preschool years are a good thing. In fact, according to developmental psychologist David Elkind, United States society tends to push children so rapidly that they begin to feel stress and pressure at a young age. Elkind argues that academic success is largely dependent upon factors out of parents' control, such as inherited abilities and a child's rate of maturation. Consequently, children of a particular age cannot be expected to master educational material without taking into account their current level of cognitive development. In short, children require development appropriate educational practice, which is education that is based on both typical development and the unique characteristics of a given child. | 3831.txt | 0 |

In fact, according to developmental psychologist David Elkind, United States society tends to push children so rapidly that they begin to feel stress and pressure at a young age. Elkind argues that academic success is largely dependent upon factors out of parents' control, such as inherited abilities and a child's rate of maturation. Consequently, children of a particular age cannot be expected to master educational material without taking into account their current level of cognitive development.

For instance, in a cross-country comparison of preschools in China, Japan, and the United States, researchers found that parents in the three countries view the purpose of preschools very differently. Whereas parents in China tend to see preschools primarily as a way of giving children a good start academically, Japanese parents view them primarily as a way of giving children the opportunity to be members of a group. In the United States, in comparison, parents regard the primary purpose of preschools as making children more independent and self-reliant, although obtaining a good academic start and having group experience are also important.
While many programs designed for preschoolers focus primarily on social and emotional factors, some are geared mainly toward promoting cognitive gains and preparing preschoolers for the formal instruction they will experience when they start kindergarten. In the United States, the best-known program designed to promote future academic success is Head Start. Established in the 1960s when the United States declared the War on Poverty, the program has served over 13 million children and their families. The program, which stresses parental involvement, was designed to serve the "whole child", including children's physical health, self-confidence, social responsibility, and social and emotional development.
Whether Head Start is seen as successful or not depends on the lens through which one is looking. If, for instance, the program is expected to provide long-term increases in IQ (intelligence quotient) scores, it is a disappointment. Although graduates of Head Start programs tend to show immediate IQ gains, these increases do not last. On the other hand, it is clear that Head Start is meeting its goal of getting preschoolers ready for school. Preschoolers who participate in Head Start are better prepared for future schooling than those who do not. Furthermore, graduates of Head Start programs have better future school grade. Finally, some research suggests that ultimately Head Start graduates show higher academic performance at the end of high school, although the gains are modest.
In addition, results from other types of preschool readiness programs indicate that those who participate and graduate are less likely to repeat grades, and they are more likely to complete school than readiness program, for every dollar spent on the program, taxpayers saved seven dollars by the time the graduates reached the age of 27.
The most recent comprehensive evaluation of early intervention programs suggests that, taken as a group, preschool programs can provide significant benefits, and that government funds invested early in life may ultimately lead to a reduction in future costs. For instance, compared with children who did not participate in early intervention programs, participants in various programs showed gains in emotional or cognitive development, better educational outcomes, increased economic self-sufficiency, reduced levels of criminal activity, and improved health-related behaviors. Of course, not every program produced all these benefits, and not every child benefited to the same extent.

] | In paragraph 1, why does the author discuss the moose and wolves on Isle Royale? | How do predators affect populations of the prey animals? The answer is not as simple as might be thought. Moose reached Isle Royale in Lake Superior by crossing over winter ice and multiplied freely there in isolation without predators. When wolves later reached the island, naturalists widely assumed that the wolves would play a key role in controlling the moose population. Careful studies have demonstrated, however, that this is not the case. The wolves eat mostly old or diseased animals that would not survive long anyway. In general, the moose population is controlled by food availability, disease and other factors rather than by wolves.
When experimental populations are set up under simple laboratory conditions, the predator often exterminates its prey and then becomes extinct itself, having nothing left to eat. However, if safe areas like those prey animals have in the wild are provided, the prey population drops to low level but not extinction. Low prey population levels then provide inadequate food for the predators, causing the predator population to decrease. When this occurs, the prey population can rebound. In this situation the predator and prey population may continue in this cyclical pattern for some time.
Population cycles are characteristic of small mammals, and they sometimes appear to be brought about by predators. Ecologists studying hare populations have found that the North American snow shoe hare follows a roughly ten-year cycle. Its numbers fall tenfold to thirty in a typical cycle, and a hundredfold change can occur. Two factors appear to be generating the cycle: food plants and predators.
The preferred foods of snowshoe hares are willow and birch twigs. As hare density increases, the quantity of these twigs decreases, forcing the hares to feed on low-quality high-fiber food. Lower birth rates, low juvenile survivorship, and low growth rates follow, so there is a corresponding decline in hare abundance. Once the hare population has declined, it takes two to three year for the quantity of twigs to recover.
A key predator of the snowshoe hare is the Canada lynx. The Canada lynx shows a ten-year cycle of abundance that parallels the abundance cycle of hares. As hare numbers fall, so do lynx numbers, as their food supply depleted.
What causes the predator-prey oscillations? Do increasing number of hares lead to overharvesting of plants, which in turn results in reduced hare populations, or do increasing numbers of lynx lead to overharvesting hares? Field experiments carried out by Charles Krebs and coworkers in 1992 provide an answer. Krebs investigated experimental plots in Canada's Yukon territory that contained hare populations. When food was added to those plots (no food effect) and predators were excluded (no predator effect) from an experimental area, hare numbers increased tenfold and stayed there-the cycle was lost. However, the cycle was retained if either of the factors was allowed to operate alone: if predators were excluded but food was not added (food effect alone), or if food was added in the presence of predators (predator effect alone). Thus both factors can affect the cycle, which, in practice, seems to be generated by conjunction of the two factors.
Predators are an essential factor in maintaining communities that are rich and diverse in species. Without predators, the species that is the best competitor for food, shelter, nesting sites, and other environmental resources tends to dominate and exclude the species with which it competes. This phenomenon is known as "competitor exclusion". However, if the community contains a predator of the strongest competitor species, then the population of that competitor is controlled. Thus even the less competitive species are able to survive. For example, sea stars prey on a variety of bivalve mollusks and prevent these bivalves from monopolizing habitats on the sea floor. This opens up space for many other organisms. When sea stars are removed, species diversity falls sharply. Therefore, from the stand point of diversity, it is usually a mistake to eliminate a major predator from a community. | 4046.txt | 1 |

Field experiments carried out by Charles Krebs and coworkers in 1992 provide an answer. Krebs investigated experimental plots in Canada's Yukon territory that contained hare populations. When food was added to those plots (no food effect) and predators were excluded (no predator effect) from an experimental area, hare numbers increased tenfold and stayed there-the cycle was lost. However, the cycle was retained if either of the factors was allowed to operate alone: if predators were excluded but food was not added (food effect alone), or if food was added in the presence of predators (predator effect alone). Thus both factors can affect the cycle, which, in practice, seems to be generated by conjunction of the two factors.
Predators are an essential factor in maintaining communities that are rich and diverse in species. Without predators, the species that is the best competitor for food, shelter, nesting sites, and other environmental resources tends to dominate and exclude the species with which it competes. This phenomenon is known as "competitor exclusion". However, if the community contains a predator of the strongest competitor species, then the population of that competitor is controlled. Thus even the less competitive species are able to survive. For example, sea stars prey on a variety of bivalve mollusks and prevent these bivalves from monopolizing habitats on the sea floor. This opens up space for many other organisms. When sea stars are removed, species diversity falls sharply. Therefore, from the stand point of diversity, it is usually a mistake to eliminate a major predator from a community. | 4046.txt | 1 |

Moose reached Isle Royale in Lake Superior by crossing over winter ice and multiplied freely there in isolation without predators. When wolves later reached the island, naturalists widely assumed that the wolves would play a key role in controlling the moose population. Careful studies have demonstrated, however, that this is not the case. The wolves eat mostly old or diseased animals that would not survive long anyway. In general, the moose population is controlled by food availability, disease and other factors rather than by wolves.
When experimental populations are set up under simple laboratory conditions, the predator often exterminates its prey and then becomes extinct itself, having nothing left to eat. However, if safe areas like those prey animals have in the wild are provided, the prey population drops to low level but not extinction. Low prey population levels then provide inadequate food for the predators, causing the predator population to decrease. When this occurs, the prey population can rebound. In this situation the predator and prey population may continue in this cyclical pattern for some time.
Population cycles are characteristic of small mammals, and they sometimes appear to be brought about by predators. Ecologists studying hare populations have found that the North American snow shoe hare follows a roughly ten-year cycle. Its numbers fall tenfold to thirty in a typical cycle, and a hundredfold change can occur. Two factors appear to be generating the cycle: food plants and predators.
The preferred foods of snowshoe hares are willow and birch twigs. As hare density increases, the quantity of these twigs decreases, forcing the hares to feed on low-quality high-fiber food. Lower birth rates, low juvenile survivorship, and low growth rates follow, so there is a corresponding decline in hare abundance. Once the hare population has declined, it takes two to three year for the quantity of twigs to recover.
A key predator of the snowshoe hare is the Canada lynx. The Canada lynx shows a ten-year cycle of abundance that parallels the abundance cycle of hares. As hare numbers fall, so do lynx numbers, as their food supply depleted.
