[ "autos have become most destructive to mankind", "people usually pay little attention to law and morality", "civilization brings much harm to people", "the lack of virtue is becoming more severe" ]
According to the passage, traffic accidents may be regarded as a social problem because _ .
The motor vehicle has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows essentially from uncivil behavior of drivers who refuse to respect the legal and moral rights of others. So the massacre on the road may be regarded as a social problem. In fact, the enemies of society on wheels are rather harmless people or ordinary people acting carelessly, you might say. But it is a principle both of law and common morality that carelessness is no excuse when one's actions could bring death or damage to others. A minority of the killers go even beyond carelessness to total negligence. Researchers have estimated that as many as 80 per cent of all automobile accidents can be attributed to the psychological condition of the driver. Emotional upsets can distort drivers' reactions, slow their judgment, and blind them to dangers that might otherwise be evident. The experts warn that it is vital for every driver to make a conscious effort to keep one's emotions under control. Yet the irresponsibility that accounts for much of the problem is not confined to drivers. Street walkers regularly violate traffic regulations; they are at fault in most vehicle walker accidents. And many cyclists even believe that they are not subject to the basic rules of the road. Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicle have been raised both at the point of manufacture and through periodic road-worthiness inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to convince people that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things pose a threat to those with whom they share the road.

[ "They absorb micronutrients unusuallywell.", "They require far less calcium than mostplants do.", "They are able to absorb nitrogen in itselemental state.", "They are typically crops raised for food." ]
According to paragraph 1, what is trueof plants that can grow in serpentine soil?
Research has shown that certain minerals are required by plants for normal growth and development. The soil is the source of these minerals, which are absorbed by the plant with the water from the soil. Even nitrogen, which is a gas in its elemental state, is normally absorbed from the soil as nitrate ions. Some soils are notoriously deficient in micro nutrients and are therefore unable to support most plant life. So-called serpentine soils, for example, are deficient in calcium, and only plants able to tolerate low levels of this mineral can survive. In modern agriculture, mineral depletion of soils is a major concern, since harvesting crops interrupts the recycling of nutrients back to the soil. Mineral deficiencies can often be detected by specific symptoms such as chlorosis (loss of chlorophyll resulting in yellow or white leaf tissue), necrosis (isolated dead patches), anthocyanin formation (development of deep red pigmentation of leaves or stem), stunted growth, and development of woody tissue in an herbaceous plant. Soils are most commonly deficient in nitrogen and phosphorus. Nitrogen-deficient plants exhibit many of the symptoms just described. Leaves develop chlorosis; stems are short and slender, and anthocyanin discoloration occurs on stems, petioles, and lower leaf surfaces. Phosphorus-deficient plants are often stunted, with leaves turning a characteristic dark green, often with the accumulation of anthocyanin. Typically, older leaves are affected first as the phosphorus is mobilized to young growing tissue. Iron deficiency is characterized by chlorosis between veins in young leaves. Much of the research on nutrient deficiencies is based on growing plants hydroponically, that is, in soilless liquid nutrient solutions. This technique allows researchers to create solutions that selectively omit certain nutrients and then observe the resulting effects on the plants. Hydroponics has applications beyond basic research, since it facilitates the growing of greenhouse vegetables during winter. Aeroponics, a technique in which plants are suspended and the roots misted with a nutrient solution, is another method for growing plants without soil. While mineral deficiencies can limit the growth of plants, an overabundance of certain minerals can be toxic and can also limit growth. Saline soils, which have high concentrations of sodium chloride and other salts, limit plant growth, and research continues to focus on developing salt-tolerant varieties of agricultural crops. Research has focused on the toxic effects of heavy metals such as lead, cadmium, mercury, and aluminum; however, even copper and zinc, which are essential elements, can become toxic in high concentrations. Although most plants cannot survive in these soils, certain plants have the ability to tolerate high levels of these minerals. Scientists have known for some time that certain plants, called hyperaccumulators, can concentrate minerals at levels a hundredfold or greater than normal. A survey of known hyperaccumulators identified that 75 percent of them amassed nickel, cobalt, copper, zinc, manganese, lead, and cadmium are other minerals of choice. Hyperaccumulators run the entire range of the plant world. They may be herbs, shrubs, or trees. Many members of the mustard family, spurge family, legume family, and grass family are top hyperaccumulators. Many are found in tropical and subtropical areas of the world, where accumulation of high concentrations of metals may afford some protection against plant-eating insects and microbial pathogens. Only recently have investigators considered using these plants to clean up soil and waste sites that have been contaminated by toxic levels of heavy metals-an environmentally friendly approach known as phytoremediation. This scenario begins with the planting of hyperaccumulating species in the target area, such as an abandoned mine or an irrigation pond contaminated by runoff. Toxic minerals would first be absorbed by roots but later relocated to the stem and leaves. A harvest of the shoots would remove the toxic compounds off site to be burned or composted to recover the metal for industrial uses. After several years of cultivation and harvest, the site would be restored at a cost much lower than the price of excavation and reburial, the standard practice for remediation of contaminated soils. For examples, in field trials, the plant alpine pennycress removed zinc and cadmium from soils near a zinc smelter, and Indian mustard, native to Pakistan and India, has been effective in reducing levels of selenium salts by 50 percent in contaminated soils.

Why does the author mention "herbs", "shrubs",and "trees"? (paragraph 5)
Research has shown that certain minerals are required by plants for normal growth and development. The soil is the source of these minerals, which are absorbed by the plant with the water from the soil. Even nitrogen, which is a gas in its elemental state, is normally absorbed from the soil as nitrate ions. Some soils are notoriously deficient in micro nutrients and are therefore unable to support most plant life. So-called serpentine soils, for example, are deficient in calcium, and only plants able to tolerate low levels of this mineral can survive. In modern agriculture, mineral depletion of soils is a major concern, since harvesting crops interrupts the recycling of nutrients back to the soil. Mineral deficiencies can often be detected by specific symptoms such as chlorosis (loss of chlorophyll resulting in yellow or white leaf tissue), necrosis (isolated dead patches), anthocyanin formation (development of deep red pigmentation of leaves or stem), stunted growth, and development of woody tissue in an herbaceous plant. Soils are most commonly deficient in nitrogen and phosphorus. Nitrogen-deficient plants exhibit many of the symptoms just described. Leaves develop chlorosis; stems are short and slender, and anthocyanin discoloration occurs on stems, petioles, and lower leaf surfaces. Phosphorus-deficient plants are often stunted, with leaves turning a characteristic dark green, often with the accumulation of anthocyanin. Typically, older leaves are affected first as the phosphorus is mobilized to young growing tissue. Iron deficiency is characterized by chlorosis between veins in young leaves. Much of the research on nutrient deficiencies is based on growing plants hydroponically, that is, in soilless liquid nutrient solutions. This technique allows researchers to create solutions that selectively omit certain nutrients and then observe the resulting effects on the plants. Hydroponics has applications beyond basic research, since it facilitates the growing of greenhouse vegetables during winter. Aeroponics, a technique in which plants are suspended and the roots misted with a nutrient solution, is another method for growing plants without soil. While mineral deficiencies can limit the growth of plants, an overabundance of certain minerals can be toxic and can also limit growth. Saline soils, which have high concentrations of sodium chloride and other salts, limit plant growth, and research continues to focus on developing salt-tolerant varieties of agricultural crops. Research has focused on the toxic effects of heavy metals such as lead, cadmium, mercury, and aluminum; however, even copper and zinc, which are essential elements, can become toxic in high concentrations. Although most plants cannot survive in these soils, certain plants have the ability to tolerate high levels of these minerals. Scientists have known for some time that certain plants, called hyperaccumulators, can concentrate minerals at levels a hundredfold or greater than normal. A survey of known hyperaccumulators identified that 75 percent of them amassed nickel, cobalt, copper, zinc, manganese, lead, and cadmium are other minerals of choice. Hyperaccumulators run the entire range of the plant world. They may be herbs, shrubs, or trees. Many members of the mustard family, spurge family, legume family, and grass family are top hyperaccumulators.

With fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else. The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well. Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: First, it will pass through sharp metal bas which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that grounders and rollers will break up everything that can be broken. Finally, the rubbish will pass under magnets, which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the final stage. The first full-scale giant recycling plants are perhaps fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long.

What's the main reason for big cities to build their own recycling plants?
With fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else. The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well.

The author argues that educating girls in developing countries is _ .
Educating girls quite possibly yields a higher rate of return than any other investment available in the developing world. Women's education may be unusual territory for economists, but enhancing women's contribution to development is actually as much an economic as a social issue. And economics, with its emphasis on incentives , provides guideposts that point to an explanation for why so many girls are deprived of an education. Parents in low-income countries fail to invest in their daughters because they do not expect them to make an economic contribution to the family: girls grow up only to marry into somebody else's family and bear children. Girls are thus seen as less valuable than boys and art kept at home to do housework while their brothers are sent to school-the prophecy becomes self-fulfilling, trapping women in a vicious circle of neglect. An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children, ensuring that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, will be educated and healthy. The vicious circle is thus transformed into a virtuous circle. Few will dispute that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 per cent for each additional year of schooling. Such big returns are impressive by the standard of other available investments, but they are just the beginning. Educating women also has a significant impact on health practices, including family planning.

What is the trend of credit-theft crime?
The big identity-theft bust last week was just a taste of what's to come. Here's how to protect your good name HERE'S THE SCARY THING about the identity-theft ring that the feds cracked last week: there was nothing any of its estimated 40,000 victims could have done to prevent it from happening. This was an inside job, according to court documents. A lowly help-desk worker at Teledata Communications, a software firm that helps banks access credit reports online, allegedly stole passwords for those reports and sold them to a group of 20 thieves at $60 a pop. That allowed the gang to cherry-pick consumers with good credit and apply for all kinds of accounts in their names. Cost to the victims: $3 million and rising. Even scarier is that this, the largest identity-theft bust to date, is just a drop in the bit bucket. More than 700,000 Americans have their credit hijacked every year. It's one of crime's biggest growth markets. A name, address and Social Security number--which can often be found on the Web--is all anybody needs to apply for a bogus line of credit. Credit companies make $1.3 trillion annually and lose less than 2% of that revenue to fraud, so there's little financial incentive for them to make the application process more secure. As it stands now, it's up to you to protect your identity. The good news is that there are plenty of steps you can take. Most credit thieves are opportunists, not well-organized gangs. A lot of them go Dumpster diving for those millions of "pre-approved" credit-card mailings that go out every day. Others steal wallets and return them, taking only a Social Security number. Shredding your junk mail and leaving your Social Security card at home can save a lot of agony later. But the most effective way to keep your identity clean is to check your credit reports once or twice a year. There are three major credit-report outfits: Equifax (at equifax.com), Trans-Union (www.transunion.com) and Experian (experian.com). All allow you to order reports online, which is a lot better than wading through voice-mail hell on their 800 lines. Of the three, I found TransUnion's website to be the cheapest and most comprehensive--laying out state-by-state prices, rights and tips for consumers in easy-to-read fashion. If you're lucky enough to live in Colorado, Georgia, Maryland, Massachusetts, New Jersey or Vermont, you are entitled to one free report a year by law. Otherwise it's going to cost $8 to $14 each time. Avoid services that offer to monitor your reports year-round for about $70; that's $10 more than the going rate among thieves. If you think you're a victim of identity theft, you can ask for fraud alerts to be put on file at each of the three credit-report companies. You can also download a theft-report form at www.consumer.gov/idtheft, which, along with a local police report, should help when irate creditors come knocking. Just don't expect justice.

The belief that people tend to behave in forbidden ways _ .
For hundreds of years, the criminal law has been built around the idea that wrongdoers must be punished for their crimes.The most basic argument for punishment is that it preserves law and order and respects for authority.From this point of view, punishment does two things.It upholds the law, and it prevents others from thinking they can get away with doing the same thing without punishment.Punishment is based on the idea that many people have a barely controlled desire to act in forbidden ways.

In the open sea, animals can often find food reliably available in particular regions or seasons (e g., in coastal areas in springtime). In these circumstances, animals are neither constrained to get the last calorie out of their diet nor is energy conservation a high priority. In contrast, the food levels in the deeper layers of the ocean are greatly reduced, and the energy constraints on the animals are much more severe. To survive at those levels, animals must maximize their energy input, finding and eating whatever potential food source may be present. In the near-surface layers, there are many large, fast carnivores as well as an immense variety of planktonic animals, which feed on plankton (small, free-floating plants or animals) by filtering them from currents of water that pass through a specialized anatomical structure. These filter-feeders thrive in the well-illuminated surface waters because oceans have so many very small organisms, from bacteria to large algae to larval crustaceans. Even fishes can become successful filter-feeders in some circumstances. Although the vast majority of marine fishes are carnivores, in near-surface regions of high productivity the concentrations of larger phytoplankton (the plant component of plankton) are sufficient to support huge populations of filter-feeding sardines and anchovies. These small fishes use their gill filaments to strain out the algae that dominate such areas. Sardines and anchovies provide the basis for huge commercial fisheries as well as a food resource for large numbers of local carnivores, particularly seabirds. At a much larger scale, baleen whales and whale sharks are also efficient filter-feeders in productive coastal or polar waters, although their filtered particles comprise small animals such as copepods and krill rather than phytoplankton. Filtering seawater for its particulate nutritional content can be an energetically demanding method of feeding, particularly when the current of water to be filtered has to be generated by the organism itself, as is the case for all planktonic animals. Particulate organic matter of at least 2.5 micrograms per cubic liter is required to provide a filter-feeding planktonic organism with a net energy gain. This value is easily exceeded in most coastal waters, but in the deep sea, the levels of organic matter range from next to nothing to around 7 micrograms per cubic liter. Even though mean levels may mask much higher local concentrations, it is still the case that many deep-sea animals are exposed to conditions in which a normal filter-feeder would starve. There are, therefore, fewer successful filter-feeders in deep water, and some of those that are there have larger filtering systems to cope with the scarcity of particles. Another solution for such animals is to forage in particular layers of water where the particles may be more concentrated. Many of the groups of animals that typify the filter-feeding lifestyle in shallow water have deep-sea representatives that have become predatory. Their filtering systems, which reach such a high degree of development in shallow- water species, are greatly reduced. Alternative methods of active or passive prey capture have been evolved, including trapping and seizing prey, entangling prey, and sticky tentacles. In the deeper waters of the oceans, there is a much greater tendency for animals to await the arrival of food particles or prey rather than to search them out actively (thus minimizing energy expenditure). This has resulted in a more stealthy style of feeding, with the consequent emphasis on lures and/or the evolution of elongated appendages that increase the active volume of water controlled or monitored by the animal. Another consequence of the limited availability of prey is that many animals have developed ways of coping with much larger food particles, relative to their own body size, than the equivalent shallower species can process. Among the fishes there is a tendency for the teeth and jaws to become appreciably enlarged. In such creatures, not only are the teeth hugely enlarged and/or the jaws elongated but the size of the mouth opening may be greatly increased by making the jaw articulations so flexible that they can be effectively dislocated. Very large or long teeth provide almost no room for cutting the prey into a convenient size for swallowing, the fish must gulp the prey down whole.

Although the vast majority of marine fishes are carnivores, in near-surface regions of high productivity the concentrations of larger phytoplankton (the plant component of plankton) are sufficient to support huge populations of filter-feeding sardines and anchovies. These small fishes use their gill filaments to strain out the algae that dominate such areas. Sardines and anchovies provide the basis for huge commercial fisheries as well as a food resource for large numbers of local carnivores, particularly seabirds. At a much larger scale, baleen whales and whale sharks are also efficient filter-feeders in productive coastal or polar waters, although their filtered particles comprise small animals such as copepods and krill rather than phytoplankton. Filtering seawater for its particulate nutritional content can be an energetically demanding method of feeding, particularly when the current of water to be filtered has to be generated by the organism itself, as is the case for all planktonic animals. Particulate organic matter of at least 2.5 micrograms per cubic liter is required to provide a filter-feeding planktonic organism with a net energy gain. This value is easily exceeded in most coastal waters, but in the deep sea, the levels of organic matter range from next to nothing to around 7 micrograms per cubic liter. Even though mean levels may mask much higher local concentrations, it is still the case that many deep-sea animals are exposed to conditions in which a normal filter-feeder would starve. There are, therefore, fewer successful filter-feeders in deep water, and some of those that are there have larger filtering systems to cope with the scarcity of particles. Another solution for such animals is to forage in particular layers of water where the particles may be more concentrated. Many of the groups of animals that typify the filter-feeding lifestyle in shallow water have deep-sea representatives that have become predatory. Their filtering systems, which reach such a high degree of development in shallow- water species, are greatly reduced. Alternative methods of active or passive prey capture have been evolved, including trapping and seizing prey, entangling prey, and sticky tentacles. In the deeper waters of the oceans, there is a much greater tendency for animals to await the arrival of food particles or prey rather than to search them out actively (thus minimizing energy expenditure). This has resulted in a more stealthy style of feeding, with the consequent emphasis on lures and/or the evolution of elongated appendages that increase the active volume of water controlled or monitored by the animal. Another consequence of the limited availability of prey is that many animals have developed ways of coping with much larger food particles, relative to their own body size, than the equivalent shallower species can process. Among the fishes there is a tendency for the teeth and jaws to become appreciably enlarged. In such creatures, not only are the teeth hugely enlarged and/or the jaws elongated but the size of the mouth opening may be greatly increased by making the jaw articulations so flexible that they can be effectively dislocated. Very large or long teeth provide almost no room for cutting the prey into a convenient size for swallowing, the fish must gulp the prey down whole.

According to paragraph 4, deep-water filter-feeders have adopted all of the following ways to obtain food EXCEPT
In the open sea, animals can often find food reliably available in particular regions or seasons (e g., in coastal areas in springtime). In these circumstances, animals are neither constrained to get the last calorie out of their diet nor is energy conservation a high priority. In contrast, the food levels in the deeper layers of the ocean are greatly reduced, and the energy constraints on the animals are much more severe. To survive at those levels, animals must maximize their energy input, finding and eating whatever potential food source may be present. In the near-surface layers, there are many large, fast carnivores as well as an immense variety of planktonic animals, which feed on plankton (small, free-floating plants or animals) by filtering them from currents of water that pass through a specialized anatomical structure.

Psychologists who study optimization compare the actual decisions made by people to theoretical ideal decisions to see how similar they are. Proponents of the worksheet procedure believe that it will yield optimal, that is, the best decisions. Although there are several variations on the exact format that worksheets can take, they are all similar in their essential aspects. Worksheets require defining the problem in a clear and concise way and then listing all possible solutions to the problem. Next, the pertinent considerations that will be affected by each decision are listed, and the relative importance of each consideration or consequence is determined. Each consideration is assigned a numerical value to reflect its relative importance. A decision is mathematically calculated by adding these values together. The alternative with the highest number of points emerges as the best decision. Since most important problems are multifaceted, there are several alternatives to choose from, each with unique advantages and disadvantages. One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables than their minds can generally comprehend and remember. On the average, people can keep about seven ideas in their minds at once. A worksheet can be especially useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question "What will I do after graduation?" A graduate might seek a position that offers specialized training, pursue an advanced degree, or travel abroad for a year. A decision-making worksheet begins with a succinct statement of the problem that will also help to narrow it. It is important to be clear about the distinction between long-range and immediate goals because long-range goals often involve a different decision than short-range ones. Focusing on long-range goals, a graduating student might revise the question above to "What will I do after graduation that will lead to successful career?"

While small may be beautiful, tall is just plain uncomfortable it seems, particularly when it comes to staying in hotels and eating in restaurants. The Tall Persons Club Great Britain (TPCGB), which was formed six months ago to campaign for the needs of the tall, has turned its attention to hotels and restaurants. Beds that are too small,shower heads that are too low, and restaurant tables with hardly any leg??room all make life difficult for those of above average height, it says. But it is not just the extra??tall whose needs are not being met. The average height of the population has been increasing yet the standard size of beds, doorways, and chairs has remained unchanged. "The bedding industry says a bed should be six inches larger than the person using it, so even a king??size bed at 6′6″ (6 feet and 6 inches) is falling short for 25% of men, while the standard 6′3″ bed caters for less than half of the male population," said TPCGB president Phil Heinricy,"Seven??foot beds would work fine." Similarly, restaurant tables can cause no end of problems. Small tables, which mean the long??legged have to sit a foot or so away from them, are enough to make tall customers go elsewhere. Some have already taken note, however. At Queens Moat Houses' Caledonian Hotel in Edinburgh, 6′6″ beds are now put in as standard after requests for longer beds from taller visitors,particularly Americans.

Exploration on the Origin of Continents The origin of continental nuclei has long been a puzzle. Theories advanced so far have generally failed to explain the first step in continent growth, or have been subject to serious objections. It is the purpose of this article to examine the possible role of the impact of large meteorites or asteroids in the production of continental nuclei. Unfortunately, the geological evolution of the Earth's surface has had an obliterating effect on the original composition and structure of the continents to such an extent that further terrestrial investigations have small chance of arriving at an unambiguous answer to the question of continental origin. Paradoxically, clues to the origin and early history of the surface features of the Earth may be found on the Moon and planets, rather than on the Earth, because some of these bodies appear to have had a much less active geological history. As a result, relatively primitive surface features are preserved for study and analysis. In the case of both the Moon and Mars, it is generally concluded from the appearance of their heavily cratered surfaces that they have been subjected to bombardment by large meteoroids during their geological history. Likewise, it would appear a reasonable hypothesis that the Earth has also been subjected to meteoroid bombardment in the past, and that very large bodies struck the Earth early in its geological history. The large crater on the Moon listed by Baldwin has a diameter of 285 km. However, if we accept the hypotheses of formation of some of the mare basins by impact, the maximum lunar impact crater diameter is probably as large as 650km. Based on a lunar analogy, one might expect several impact craters of at least 500km diameter to have been formed on Earth. By applying Baldwin's equation, the depth of such a crater should be about 20km. Baldwin admits that his equation gives excessive depths for large craters so that the actual depth should be somewhat smaller. Based on the measured depth of smaller lunar crater. Baldwin's equation gives the depth of the zone of brecciation for such a crater as about 75km. The plasticity of the Earth's mantle at the depth makes it impossible to speak of "bracciation" in the usual sense. However, local stresses may be temporarily sustained at that depth, as shown by the existence of deep-focus earthquakes. Thus, short-term effects might be expected to a depth of more than 50km in the mantle. Even without knowing the precise effects, there is little doubt that the formation of a 500-km crater would be a major geological event. Numerous authors have considered the geological implications of such an event. Donn et al. have, for example, called on the impact of continent-size bodies of sialic composition to from the original continents. Two major difficulties inherent in this concept are the lack of any known sialic meteorites, and the high probability that the energy of impact would result in a wide dissemination of sialic material, rather than its concentration at the point of impact. Gilvarry, on the other hand, called on meteoroid impact to explain the production of ocean basins. The major difficulties with this model are that the morphology of most of the ocean basins is not consistent with impact, and that the origin and growth of continents is not adequately explained. We agree with Donn at al. that the impact of large meteorites or asteroids may have caused continent formation, but would rather think in terms of the localized addition of energy to the system, rather than in terms of the addition of actual sialic material.

In contrast to the earlier linguists, modern linguists tend to .
When one looks back upon the fifteen hundred years that are the life span of the English language, he should be able to notice a number of significant truths. The history of our language has always been a history of constant change-at times a slow, almost imperceptible change, at other times a violent collision between two languages. Our language has always been a living growing organism, it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. 『At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans.』 At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty. As we consider our changing language, we should note here two developments that are of special and immediate importance to us.

When one looks back upon the fifteen hundred years that are the life span of the English language, he should be able to notice a number of significant truths. The history of our language has always been a history of constant change-at times a slow, almost imperceptible change, at other times a violent collision between two languages. Our language has always been a living growing organism, it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. 『At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans.』 At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty. As we consider our changing language, we should note here two developments that are of special and immediate importance to us.

The original chocolate drink was made from the seeds of the cocoa tree by South American Indians. The Spanish introduced it to the rest of the world during the 1500's. And although it was very expensive, it quickly became fashionable. In London shops where chocolate drinks were served became important meeting places. Some still exist today. The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the "Potato Famine" of 1845-6, and thousands more were forced to emigrate to America. There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's. According to an Arabic legend, coffee was discovered when a goatherd named Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and experienced the "wide-awake" feeling that one-third of the world's population now starts the day with.

Children would play with fire until their hands are burnt away if _ .
Fear and its companion pain are two of the most useful things that man and animals possess if they are used. If fire didn't hurt when it burned, children would play with it until their hands were burned away. Similarly, if pain existed but fear didn't, a child could burn itself again and again because fear would not warn it to keep away from the fire that had burnt it before. A really fearless soldier-and some do exist-is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which man and animals might soon die out. In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. The important thing is not to let fear rule you, but instead, to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take. In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is well. In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing into your house, and you may not want to go and live in a desert where there are no airplanes. In this case, fear has given you its warning, you have examined it and decided on your course of action, so fear of the particular danger is no longer of any use to you, and you have to try to overcome it.

When I was studying English at a training center in Washington D.C. in 1998, I shared a house with two young Americans, Jim, and Steve. Jim was studying French and Steve Chinese, both at the Foreign Service Institute. We shared many things in common, but we also thought and acted quite differently. Steve was interested in speaking Chinese. He always tried every opportunity to talk with me with his very English-like pronunciation. I was often touched with his diligence. However, I wanted to practice English with him, too. So we often speak at the same time in the other's mother tongue. Jim was fresh from college and the youngest of the three. He was going out all the time. The only time we met was at breakfast. There was a small round table in our kitchen, where we sat around to enjoy our food. Steve had Chinese fast food such as dumplings or noodles, and I ate bread and boiled eggs. But Jim often just drank a cup of tea because he had nothing in his bridge. He was too busy dating pretty French girls to do any shopping. I often offered him some of my food. But Steve told me in his poor Chinese that I didn't need to do that. He said that it was Jim's own fault and that it served him right. Although he was learning Chinese, he still held his American sense of value. Two years later, I returned to china. The three of us still keep in touch. Jim now works in a travel agency in Paris. He got married to one of the pretty girls. He wrote to tell us that now he can enjoy a delicious breakfast with his beautiful wife every morning in their comfortable living room. Steve wants to work in china. And I'm helping him with this. I have introduced him to the dean of the Overseas Section of our university. He is very interested in Steve. He wants to know if Steve can work here teaching the overseas students Chinese. I have sent the message to Steve. I'm sure he'd be very happy to accept the job. However, I hope he could try harder to improve himself.

He was going out all the time. The only time we met was at breakfast. There was a small round table in our kitchen, where we sat around to enjoy our food. Steve had Chinese fast food such as dumplings or noodles, and I ate bread and boiled eggs. But Jim often just drank a cup of tea because he had nothing in his bridge. He was too busy dating pretty French girls to do any shopping. I often offered him some of my food. But Steve told me in his poor Chinese that I didn't need to do that. He said that it was Jim's own fault and that it served him right. Although he was learning Chinese, he still held his American sense of value. Two years later, I returned to china. The three of us still keep in touch. Jim now works in a travel agency in Paris. He got married to one of the pretty girls. He wrote to tell us that now he can enjoy a delicious breakfast with his beautiful wife every morning in their comfortable living room. Steve wants to work in china. And I'm helping him with this. I have introduced him to the dean of the Overseas Section of our university. He is very interested in Steve. He wants to know if Steve can work here teaching the overseas students Chinese. I have sent the message to Steve. I'm sure he'd be very happy to accept the job. However, I hope he could try harder to improve himself. Otherwise, all the overseas students would speak with his terrible pronunciation!

From the last paragraph, we can learn that _ .
When I was studying English at a training center in Washington D.C. in 1998, I shared a house with two young Americans, Jim, and Steve. Jim was studying French and Steve Chinese, both at the Foreign Service Institute. We shared many things in common, but we also thought and acted quite differently.

According to the first paragraph, which one of the following is TRUE of the oil price?
As the oil price climbed towards $100 a barrel during the past few weeks, big Western oil firms were reporting their results for the third quarter. Record oil prices, it turns out, do not translate into record profits. Oil is now close to exceeding the record set in 1979 of between $100 and $110, depending on how you adjust for inflation and what benchmark you use. Yet almost without exception, big oil firms' profits are falling from the peaks reached last year. Exxon Mobil, for example, reported a 10% drop in profits in the third quarter, and BP's fell even more sharply. Profits also fell at Chevron, ConocoPhillips and Eni. They rose at Total and Royal Dutch Shell-but only thanks to exchange-rate fluctuations and one-off asset sales. Analysts at Citigroup calculate that, measured in dollars, the biggest oil firms' earnings fell by 15% on average. To be fair, the oil price has surged most dramatically since the end of September, although it was also buoyant in the third quarter. The majors' poor showing also reflects lower profits from refining, as the difference in price between petrol and crude oil has fallen from the exceptionally high levels of recent months. But the fact remains that oil giants are struggling to pump more oil and gas. In part, this is due to a quirk of the rules that oblige Western oil firms to share the crude they produce with state-owned oil firms in many countries. The contracts in question often stipulate that as the price goes up, the volume of oil the foreigners receive decreases. Worse, several countries are changing contracts or tax rules in ways that will further erode the Western oil firms' profits-and in some cases are throwing them out altogether. Rising costs are also a problem. Exxon, which is known for its stringent financial discipline, saw costs rise almost twice as fast as revenue in the third quarter. The shortage of labour and equipment that is feeding this inflation is also causing delays to new projects. And there are not enough new projects in the pipeline. The International Energy Agency reckons that the expansion plans of the big Western and state-owned oil firms will leave the world 12.5m barrels per day short of requirements in 2015. Despite this looming deficit and the glaring price signal, all the big companies except Total produced less oil and gas in the third quarter than they did in the same period last year. According to Citigroup, the average decline in overall output was 3.3%. If the relatively steady supply of natural gas is stripped out, the numbers look even worse: oil production fell by 9% on average. No matter how high the price goes, the oil majors cannot make a profit from oil they do not produce.

The typical features of Sherlock Holmes were all EXCEPT
Within that exclusive group of literary characters who have survived through the centuries--from Hamlet to Huckleberry Finn--few can rival the cultural impact of Sherlock Holmes. Since his first public appearance 20 years ago, the gentleman with the curved pipe and a taste for cocaine, the master of deductive reasoning and elaborate disguise, has left his mark everywhere--in crime literature, film and television, cartoons and comic books. At Holmes' side, of course, was his trusted friend Dr. Watson. Looming even larger, however, was another doctor, one whose medical practice was so slow it allowed him plenty of time to pursue his literary ambition. His name: Arthur Conan Doyle. As the creator of these fictional icons, Conan Doyle has himself become something of a cult figure, the object of countless critical studies, biographies and fan clubs. Conan Doyle was born in Edinburgh in 1859, in a respectable middle-class Catholic family. Still, it was far from an easy life. There was never enough money; they moved frequently in search of lower rents; and his father, a civil servant and illustrator was an alcoholic who had to be institutionalized. Yet the early letters he wrote to his mother are surprisingly optimistic, concerned mainly with food, clothes, allowances and schoolwork. At 14 came his first unforgettable visit to London, including Madame Tussaud's, where he was "delighted with the room of Horrors, and the images of the murderers." A superb student, Conan Doyle went on to medical school, where he was attracted by Dr. Joseph Bell, a professor with an uncanny ability to diagnose patients even before they opened their mouths. For a time he worked as Bell's outpatient clerk and would watch, amazed, at how the location of a callus could reveal a man's profession, or how a quick look at a skin rash told Bell that the patient had once lived in Bermuda. In 1886, Conan Doyle outlined his first novel, A Study in Scarlet, which he described as "a simple tale of mystery to make a little extra money." Its main character, initially called Sherringford Hope and later called Sherlock Holmes, was based largely on Bell. But Holmes' first appearance went almost unnoticed, and the struggling doctor devoted nearly all of his spare time to writing long historical novels in the style of Sir Walter Scott-novels that he was convinced would make his reputation. It wasn't to be. In 1888, Holmes reappeared in A Scandal in Bohemia, a short story in Strand Magazine. And this time, its hero took an immediate hit and Conan Doyle's life would never be the same.
