Global warming is a trend toward warmer conditions around the world. Part of the warming is natural; we have experienced a 20,000 -year -long warming as the last ice age ended and the ice 36. melted(I) away. However, we have already reached temperatures that are in 37. line(G) with other minimum-ice periods, so continued warming is likely not natural. We are 38. Contributing(C) to a predicted worldwide increase in temperatures 39. ranging(K) between 1℃ and 6℃over the next 100 years. The warming will be more 40. dramatic(D) in some areas, less in others, and some places may even cool off. Likewise, the 41. impact(F) of this warming will be very different depending on where you are—coastal areas must worry about rising sea levels, while Siberia and northern Canada may become more habitable (宜居的) and 42. appealing(A) for humans than these areas are now.The fact remains, however, that it will likely get warmer, on 43. average(B), everywhere. Scientists are in general agreement that thewarmer conditions we have been experiencing are at least in part the result of a human-induced global warming trend. Some scientists 44. maintain(H)that the changes we are seeing fall within the range of random (无规律的) variation —some years are cold, others warm, and we have just had an unremarkable string of warm years 45. recently(L)—but that is becoming an increasingly rare interpretation in the face of continued and increasing warm conditions.A)appealingB)averageC)contributingD)dramaticE)frequentlyF)impactG)lineH)maintainI)meltedJ)persistK)rangingL)recentlyM)resolved N)sensible O) shock。

四级15选10填空练习Passage 1Questions 47 to 56 are based on the following passage.Perhaps like most Americans you have some extra pounds to 47 . You may even have tried a fad diet or two, but found yourself right back where you started. The key to weight loss is regular 48 activity. And surprisingly, you don’t have to give up eating or make the gym your second home to see long-term, 49 effects.You body needs a certain amount of energy to maintain basic 50 such as breathing, blood circulation and digestion. The energy required to keep your organs functioning is referred to as the resting or basal metabolic rate.Any time you are active, 51 energy is required. It is obtained from glycogen and fat stored in the blood, liver, and muscles. The key to losing weight is to draw on the fat rather than on the carbohydrate reserves.Which of the two energy sources you use depends on the intensity and 52 of your activity. The higher the intensity, the more your body will pull from the stored carbohydrates. The lower the intensity, the more your body will 53 on fat as its fuel.Aerobic exercise is most 54 for weight loss. When you perform aerobic activities you 55 contract large muscle groups such as your legs and arms. Walking, running, rollerblading, swimming, dancing, and jumping jacks are all forms of aerobic activity.Surprisingly, if your aerobic activity is low to moderately intense and of long duration, you will burn more fat than if you had 56 in a short burst of high-intensity exercise. In short, a brisk 30-minute walk will burn fat while a 100-yard sprint will burn glycogen.[A] positive [B] additional [C] duration [D] effective[E] shed [F] physical [G] food [H] functions[I] participated [J] rely [K] cut [L] repeatedly[M] uses [N] little [O] obviousPassage 2Questions 47 to 56 are based on the following passage.The comparatively treeless plains of North Africa have suffered a progressive drying up, both 47 and man-made, but the region was 48 so rich in fertile soil that the district we now know as the Libyan Desert was, in the old days, part of the granary (粮仓) of the Roman Empire, and the centre of the Sahara 49 a busy trading population for a long period. That was when there were 50 in plenty and the fields were the traditional “fields of the woods” —clearings in the forest—and therefore always tree 51 .It is the trees that lift the water and send 52 into the air so that it may fall as dew or rain further on. Trees reduce the speed of the wind, and provide shelter and shade; the roots 53 minerals in the soil and these are carried to the leaves which, when they have fulfilled their function, return to the earth, giving the soil the combination of minerals that plants require.But through the ages Africa has been 54 . Successive invaders have felled the forest to provide grazing lands for their flocks and herds. With the removal of the essential tree cover, the water 55 was broken, the earth became feverish and sick, and in course of time was unable to support those who had broken the 56 of life by removing the earth’s green mantle—the trees.A) moisture B) cycle C) water D) rhythmE) contain F) trap G) once H) surroundedI) fed J) exploited K) social L) naturalM) forest N) usually O) treesPassage 3Questions 47 to 56 are based on the following passage.Rock and roll is a genre of popular music that evolved in the United States in the late 1940s and early 1950s. Its 47 lie mainly in blues, rhythm and blues, country, folk, gospel, and jazz. The style subsequently spread to the rest of the world and developed further, leading ultimately to 48 rock music.The term “rock and roll” now covers at least two different meanings, both in common usage. The American Heritage Dictionary and the Merriam-Webster Dictionary both 49 rock and roll as synonymous with rock music.50 , defines the term as referring specifically to the music of the 1950s.Classic rock and roll is 51 played with one or two electric guitars, a string bass or an electric bass guitar, and a drum kit. In the 52 rock and roll styles of the late 1940s, either the piano or saxophone was often the lead instrument, but these were generally 53 or supplemented by the guitar in the middle to late 1950s.The massive popularity and eventual worldwide view of rock and roll gave it a 54 social impact. Far beyond simply a musical style, rock and roll, as seen in movies and in the new medium of television, 55 lifestyles, fashion, attitudes, and language. It went on to spawn various sub-genres, often without the initially 56 backbeat, that are now more commonly called simply “rock music” or “rock”.A) define B) characteristic C) unique D) rootsE) usually F) Basically G) earliest H) influencedI) followed J) modern K) explanation L) ConverselyM) replaced N) prepare O) seldomPassage 4Questions 47 to 56 are based on the following passage.There’s no question that the Earth is getting hotter. The real questions are: How much of the warming is our fault, and are we 47 to slow the devastation by controlling our insatiable 48 for fossil fuels?Global warming can seem too 49 to worry about, or too uncertain—something projected by the same computer 50 that often can’t get next week’s weather right. On a raw winter day you might think tha t a few degrees of warming wouldn’t be such a bad thing anyway. And no doubt about it: Warnings about 51change can sound like an environmentalist scare tactic, meant to force us out of our cars and restrict our lifestyles.Comforting thoughts, perhaps. Unfortunately, however, the Earth has some discomforting news. From Alaska to the snowy peaks of the Andes the world is heating up right now, and fast. Globally, the 52 is up 1°F over the past century, but some of the coldest, most remote spots have warmed much more. The results aren’t pretty. Ice is 53, rivers are running dry, and coasts are 54, threatening communities.The 55 are happening largely out of sight. But they shouldn’t be out of mind, because they are omens of what’s in store for the 56 of the planet.[A]remote [B]techniques [C]consisting [D]rest[E]willing [F]climate [G]skill [H]appetite[I]melting [J]vanishing [K]eroding [L]temperature[M]curiosity [N]changes [O]skillfulPassage 5Questions 47 to 56 are based on the following passage.Shopping habits in the United States have changed greatly in the last quarter of the 20th century. Early in the 1900s most American towns and cities had a Main Street. Main Street was always the 47 of a town. This street was lined on the both sides with many 48 businesses. Here, shoppers walked into stores to look at all sorts of merchandise: clothing, furniture, hardware, groceries. In addition, some shops offered 49 . There shops included drugstores, restaurants, shoe repair stores, and barber or hairdressing shops. But in the 1950s, a change began to 50 place. Too many automobiles had crowded into Main Street while too few parking places were 51 to shoppers. Because the streets were crowded, merchants began to look with interest at the open spaces outside the city limits. Open space is what their car driving customers 52 . And open space is what they got when the first shopping centre was built. Shopping centers, or rather malls, 53 as a collection of small new stores away from crowded city centers. Attracted by hundreds of free parking space, customers were drawn away from 54 areas to outlying malls. And the growing 55 of shopping centers led in turn to the building of bigger and better stocked stores. By the late 1970s, many shopping malls had almost developed into small cities themselves. In addition to providing the 56 of the stop shopping, malls were transformed into landscaped parks, with benches, fountains, and outdoor entertainment.[A]designed [B]take [C]heart [D]needed[E]though [F]convenience [G]services [H]fame[I]various [J]popularity [K]cosmetics [L]started[M]downtown [N]available [O]cheapnessPassage 6Questions 47 to 56 are based on the following passage.Have you ever been afraid to talk back when you were treated ____47 ___? Have you ever bought something just because the salesman talked you into it? Are you afraid to ask someone for a date.Many people are afraid to assert(表现)themselves. Dr. Alberti thinks it's because their self-respect is low. "Our whole ____48 ___ is designed to make people distrust themselves," says Alberti. "There's always '____49 ___' around-a parent, a teacher, a boss-who 'knows better'. These superiors often gain when they chip(削弱) away at your self-image."But Alberti and other scientists are doing something to help people ____50 ___ themselves. They ____51 ___ "assertiveness training" courses-At for short. In the AT courses people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be more ____52 ___ without hurting other people.In one way. learning to speak out is to ____53 ___ fear. A group taking a course will help the timid person to lose his fear. But AT uses an even stronger ____54 ___-the need to share. The timid person speaks out in the group because he wants to tell how he feels.Whether or not you speak up for yourself depends on your self-image. If someone you face is more "important" than you, you may feel less of a person. You start to ____55 ___ your own good sense.You go by the other person's ____56___ . But, why should you? AT says you can get to feel good about yourself. And once you do, you can learn to speak out.[A] doubt [B] active [C] system [D] offer[E] unfairly [F] unfortunately [G] motive [H] image[I] peace [J] demand [K] ask [L] superior[M] overcome [N] confidence [O] roarPassage 7Questions 47 to 56 are based on the following passage.Perhaps like most Americans you have some extra pounds to 47 .

It was started to 1 the importance of working women and bring their problems to 2 . However, 3 the day is not a one-day agenda. The real challenge lies in the natural flow of feelings----honoring and celebrating womanhood on a particular March 8 only to forget its importance the next day is 4 . In countries like South Africa, the people celebrate the national Women’s day on August 9 every year with a variety of events. Wom en’s Day on August 9 marks the day, in 1956, when 20,000 women 5 on the Union Buildings in Pretoria to protest against one of the cornerstones of apartheid (种族隔离) -----the passed laws.

But the environment must also have a profound effect, since if competition is important to the parents, it is likely to become a major factor in the lives of their children. One place where children soak up A characteristics is school, which is, by its very 2 , a highly competitive institution. Too many schools adopt the win at all costs moral standard and measure their success by sporting achievements. The 3 passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B type fellows. Being too keen to win can have dangerous consequences: remember that Pheidippides, the first marathon runner, dropped dead seconds after saying: “Rejoice, we conquer!”By far the worst form of competition in schools is the disproportionate emphasis on examinations. It is a rare school that allows pupils to concentrate on those things they do well. The merits of competition by examination are somewhat 4 , but competition in the certain knowledge of failure is 5 harmful.Obviously, it is neither practical nor 6 that all A youngsters change into B’s. The world needs types, and scho ols have an important duty to try to fit a child’s personality to his possible future employment. It is top management.If the preoccupation of schools with academic work was 7 , more time might be spent teaching children surer values. Perhaps selection for the caring professions, especially medicine, could be made less by good grades in chemistry and more by such considerations as 8 and sympathy.

Tests and interviews with hundreds of people born in a single week in 1958 1 illustrated the handicap of educational underachievement. The effects were seen in unemployment, low incomes, depression and social 2 .Those who left school at 16 with poor basic skills had been employed for up to four years less than good readers at the time they reached 37. Professor John Bynner of City University, who 3 out the research, said that today’s 4 people would face even greater problems because the supply of manual jobs had 5 up. Poor readers were twice as likely to be on a low 6 and four times as likely to live in a household where neither partner worked. Women in this position were five times as likely to be classified as 7 , while both sexes tended to feel they had no control over their lives, and to be 8 of others. Those with low literacy and numeracy skills were seldom involved in any 9 organization and much less likely than others to have 10 in a general election. There had been no improvement in the level of interviewees since the sample was surveyed at the age of 21.

Many people 1 believe the term drug refers only to some sort of medicine or an illegal 2 taken by drug addicts. They don't realize that familiar substances such as alcohol and tobacco are also drugs. This is why the more 3 term substance is now used by many physicians and psychologists. The phrase substance abuse is often used instead of drug abuse to make clear that substances such as alcohol and tobacco can be just as 4 misused as heroin and cocaine.We live in a society in which the medicinal and social use of substances (drugs) is pervasive; an aspirin to quiet a headache, some wine to be 5 , coffee to get going in the morning, a cigarette for the nerves. When do these socially acceptable and apparently constructive uses of a substance become misuses? First of all, most substances taken in excess will produce 6 effects such as poisoning or intense perceptual distortions. Repeated use of a substance can also lead to physical addiction or substance dependence. Dependence is marked first by an increased tolerance, with more and more of the substance required to produce the 7 effect, and then by the appearance of unpleasant withdrawal symptoms when the substance is 8 .Drugs (substances) that affect the central nervous system and alter perception, mood, and behavior are known as psychoactive substances. Psychoactive substances are commonly grouped according to whether they are stimulants, depressants, or hallucinogens (致幻剂). Stimulants initially speed up or 9 thecentral nervous system, whereas depressants slow it down. Hallucinogens have their primary effect onperception, distorting and altering it in a variety of ways including producing hallucinations (幻觉). These are the substances often called psychedelic (迷幻药) (from the Greek word meaning “mind manifesting”) because t hey seemed to radically 10 one's state of consciousness.A) destroy B) harmfully C) mistakenly D) certainlyE) sociable F) alter G) chemical H) stimulusI) negative J) activate K) neutral L) desiredM) popular N) discontinued O) disappearedC G K B E I L N J F(六)The majority of people, about nine out of ten, are right-handed. Up until recently, people who were left-handed were considered to be 1 , and once children showed this tendency they were forced to use their right hands. Today left-handedness is generally 2 , but it is still a 3 in a world where most people are right-handed. For example, most tools and 4 are still designed for right-handed people.In sports, by 5 , doing things with the left hand or foot, is often an advantage. Throwing, kicking, punching or batting from the “wrong” side may result in throwing off many opponents who are more 6 to dealing with the majority of players who are right-handed. This is why, in many games at a professional level, a higher proportion of players are left-handed than in the population as a whole.The word “right” in many languages means “correct” or is 7 with lawfulness, whereas the word associated with “left”, such as “sinister”, generally have 8 associations. Moreover,among a number of primitive peoples there is a close association between death and left hand.In the past, in most Western societies, children were often forced to use their right hands, 9 to write with. In some cases the left hand was 10 behind the child’s back so it could not be used. If, in the future, they are allowed to choose, they will certainly be more left-handers, and probably fewer people with minor psychological disturbances as a result of being forced to use their right hands.A) tied B) abnormal C) comparison D) contrastE) accustomed F) negative G) connected H) minorityI) implements J) illegal K) especially L) speciallyM) disadvantage N) opposed O) acceptedB O M I D E G F K A（七）Perhaps like most Americans you have some extra pounds to 47 . You may even have tried a fad diet or two, but found yourself right back where you started. The key to weight loss is regular 48 activity. And surprisingly, you don't have to give up eating or make the gym your second home to see long-term, 49 effects.You body needs a certain amount of energy to maintain basic 50 such as breathing, blood circulation and digestion. The energy required to keep your organs functioning is referred to as the resting or basal metabolic rate.Any time you are active, 51 energy is required. It is obtained from glycogen and fat stored in the blood, liver, and muscles. The key to losing weight is to draw on the fat rather than on the carbohydrate reserves.Which of the two energy sources you use depends on the intensity and 52 of your activity.

我的进攻已经持续了三天，但是我们并没有取得多少进展。

师长命令我们营绕到敌人后方，在夜间发动突然袭击。

为此我们要穿过沼泽地，和我们很多人担心会陷入泥潭之中。

我们营长决定赌一把。

幸运的是，由于严寒天气使沼泽结冰，我们到达我们的目的地在黎明前，从敌人后方发起进攻。

这就扭转了战局。

敌人，猝不及防，很快就投降了。

The offensive had lasted three days, but we had not gained much ground. The division commander instructed our battalion to get around to the rear of the enemy at night and launch a surprise attack. To do this we have to cross a marshland, and many of us were afraid we might get bogged down in the mud. Our battalion commander decided to take a gamble. Luckily enough, thanks to the severely cold weather which had made the marshland freeze over, we arrived our destination before dawn and began attacking the enemy from the rear. This had turned the tide of the battle. The enemy, caught off guard, soon surrendered.好的开始，成功的一半，俗话说。

Unit EightPassage 2When a person feels low, blue, or down in the clumps, it usually means he has been hurt, disappointed, or saddened by something that causes a confused and listless feeling. There is 11 a type of music called "the blue", a low, mournful, sad sound to 12 these universal human feelings.Depression is another name for this mood. Feeling depressed is a normal and natural 13 to experiences of loss, failure, and undeserved bad luck. Indeed, it has been pointed out that without depression, we would 14 much of the world's great tragic literature, music, and art.In some cases, however, depression becomes something more than just 15 feelings of blues or letdown. A large number of people suffer from what psychiatrists call "depressive illness. " Depressive illness is more 16 and lasts longer than common listless feelings. Sometimes a serious 17 of depression can begin with the loss of a loved one or a change of job. Many times, in very18 cases, there doesn't seem to be any circumstance serious enough to have caused the depression.Some psychiatrists suggest that the key feature in depression is change. The person becomes different from the way before the onset of his depression. He may even become the opposite of his usual self. There are many examples: the businessman who becomes a wanderer, the mother who wants to 19 her children and herself. Instead of seeking satisfaction and pleasure, the depressed person 20 it.A growing world population and the discoveries of science may 11 this pattern of distribution in the future. As men slowly learn to master diseases, control floods, prevent famines, and stop wars, fewer people die every year; and in 12 the population of the world is 13 increasing. In 1925 there were about 2,000 million people in the world; by the end of the century there may well be over 4,000 million.When numbers rise the 14 mouths must be fed. New lands must be I bought under cultivation, or land already farmed made to 15 larger crops. In some areas the accessible land is largely so intensively 16 that it will be difficult to make it provide more food. In some areas the population is so dense that the land is parceled out in units too 17 to allow for much improvement in farming methods. Were a larger part of this farming population drawn off into industrial occupations, the land might be farmed much more productively by modern methods.There is now a race for science, technology, and industry to keep the 18 of food rising faster than the number of people to be fed. New strains of crops are being developed which will thrive in 19 climates; irrigation and dry-farming methods bring poor lands under the plough, dams hold back the waters of great rivers to 20 water for the fields in all seasons and to provide electric power for new industries; industrial chemistryprovides fertilizers to suit particular soils; aero planes spray crops to destroy insects and many plant diseases.A. ensureB. violentlyC. alterD. harmfulE. cultivatedF. uniqueG. transplantedH. yieldI. consequenceJ. outputK. extraL. steadilyM. tinyN. unfavorableO. produceUnit TenPassage 2In the United States, it is not 11 to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11: 00 p. m. . If someone receives a call during sleeping hours, he 12 it's a matter of life and death. The time chosen for the call 13 its importance.In 14 life, time plays a very important part. In the U. S. A. , guests tend to feel they are not highly regarded if the 15 to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in 16 because plans which are made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts of the world. Thus, misunderstandings 17 between people from cultures that treat time differently.Promptness is valued 18 in American life, for example. If people are not prompt, they may be regarded as impolite or not fully responsible. In the U. S. no one would think of keeping a business 19 waiting for an hour, it would be too impolite. A person who is 5 minutes late is 20 to make a shortapology. If he is less than 5 minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence.A. highlyB. engagementC. customaryD. socialE. informF. invitationG. advanceH. absenceI. heavily J. associate K. expected L. assumesM. habitual N. arise O. communicatesUnit ElevenPassage 2Personality is, to a large extent, inherent—A-type parents, usually bring about A-type children. But the environment must also have a 11 effect, wince if competition is important to the parents it is likely to become a major 12 in the lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools 13 the " win at all costs" moral standard and measure their success by sporting achievements. The current 14 for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being 15 keen to win can have dangerous consequences: remember that Pheidippides, the first marathon runner, dropped dead seconds after saying; "cheers, we conquer!"By far the worst form of competition in schools is the extreme 16 on examinations. It is a rare school that allows pupils to 17 on those things they do well. The merits of competition by examination are somewhat 18 , but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither 19 nor desirable that all A youngsters change into B's. The world needs types, andschools have an important duty to try to 20 a child's personality to his possible future employment.

Once you are in habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body. Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often 12 to be. A certain amount of stress is 13 to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor 14 and ill health.The amount of stress a person can 15 depends very much on the individual. Some people are not afraid of stress, and such characters are 16 prime material for managerial responsibilities. Others lose heart at the first signs of 17 difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so 18 , but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued 19 to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot 20 stress from our lives(it would be unwise to do so even if we could) , we need to find ways to deal with it.A. cancelB. paceC. extremeD. automaticallyE. removeF. vitalG. performanceH. supposedI. rate J. exposure K. achievement L. unusualM obviously N withstand O harshUnit ThirteenPassage 2What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist, a leader, an active person who 11 life, people and excitement. Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You 12 to be a pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference, as well as the effect that colors have on human beings. They tell us, among other 13 , that we do not choose our favorite color as we grow up—we are born with our preference. If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.Colors do 14 our moods—there is no doubt about it. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is 15 .A black bridge over the Thames River, near London, used to be the 16 of more suicides than any other bridge in the area—until it was repainted green. The number of suicide attempts immediately fell 17 ; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and 18 colors make people not only happier but more active.

In 1985, Regent Beryl Milburn produced a report blasting the University of Texas System administration for not 12 women. The University was rated among the lowest for the system. In a 1587 update, Milburn 13 and praised the progress that was made and called for even more 14One of the positive results from her study was a system-wide program to inform women of available administrative jobs. College of Communication Associate Dean, Patricia Witherspoon, said it is important that woman be 15 when it comes to relocating if they want to 16 in the ranks.Although a woman may face a chilly 17 on campus, many times in order for her to succeed, she must rise above the problems around her and concentrate on her work.Until women make up a greater 18 of the senior positions in the University and all academia, inequalities will exist. "Women need to spend their energies and time doing scholarly activities that are important here at the University. " Spirduso said. "If they do that they will be 19 in this system.

They must act on the belief that all students can learn. They must recognize 13 differences in their students and adjust their practice 14 . They must know that their mission extends beyond developing the cognitive capacity of their students. They must be 15 with their students' self-concept, with their motivation, and with the development of character.Teachers must know the subjects they teach and how to teach them. They must 16 specialized knowledge of how to convey a subject to students. Teachers are responsible for managing and monitoring student learning. They must call on 17 methods to meet their goals, knowing and being able to 18 a variety of instructional skills. Teachers must think systematically about their practice and learn from experience, seeking the 19 of others and drawing on education research and scholarship to improve their practice.As members of learning communities, teachers contribute to school effectiveness by collaborating with other professionals. They take ___20 ofcommunity resources, cultivating knowledge of their school's community as a powerful resource for learning.A. employB. adviceC. quantityD. committedE. commandF. consultedG. manualH. approximatelyI. concerned J. advantage K. multiple L. accordinglyM. individual N. embrace O. qualityUnit SixteenPassage 2If you are looking for information, library shelves are a good place to start. But if you need up-to-the-minute data or have specialized needs, you may find a computerized database more useful, less expensive, and less time 11 .A database, a file of information on one subject or family of subjects, can be stored and 12 in a computer's memory. The speed of the computer then 13 you to recall any item in this file almost 14The three main types of databases are statistical, bibliographic, and full text. Statistical databases store 15 amounts of numerical data, such as wage and price indexes, census information, foreign 16 rates and bond prices. Bibliographic databases store references to and summaries of articles in periodicals and newspapers. Full-text databases offer the complex texts of such 17 as newspaper, magazine, and journal articles.Thousands of databases exist today, and their numbers are growing. Many companies have their in-house database, which is 18 to employees through computer terminals or microcomputers. In addition, several hundred commercial databases are now available to the 19 , with literally millions of items of information readily obtainable.

Disability is not just something that happens to other people: as we get older, many of us will become less 13 , hard of hearing or have failing eyesight. Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many 14 disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form of a mental illness. All are affected by people's attitude towards them.Disabled people face many 15 barriers. Next time you go shopping or to work or to visit friends, imagine how you would 16 if you could not get up steps, or on to buses and trains. How would you cope if you could not see where you were going or could not hear the traffic? But there are other barriers; 17 can be even harder to break down and ignorance 18 represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through, so it is important to 19 attention to these barriers and show that it is the individual person and their ability, not their disability, which 20A. inevitablyB. evaluationsC. estimatesD. manageE. aloneF. countsG. prejudiceH. physicalI. mobile J. indifferently K. withdraw L. progressiveM. regular N. accounts O. drawUnit EighteenPassage 2Social customs and ways of behaving change. Things which were considered impolite many years ago are now11 . Just a few years ago, it was 12 impolite behavior for a man to smoke on the street. No man who thought of himself as being a gentleman would make a 13 of himself by smoking when a lady was in a room. Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it 14 ? What about table manners? Should you use both hands when you are eating? Should you leave one in your lap, or on the table?The Americans and the British not only speak the same language but also 15 a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a woman or offer their seat to a woman, and so will most Americans. 16 is important both in England and in America. That is, if a dinner invitation is for 7 o'clock, the dinner guest either arrives 17 to that time or calls up to explain his 18The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable— 19 if they are your guests. There is an old story about a man who gave a formal dinner party. When the food was served, one of the guests started to eat his peas with a knife.

Despite 11 alarms, the country escaped any postwar depression and lived in a 12 of boom. An economic survey of the year 1955, a typical year of the 1950's, may be typical as 13 the rapid economic growth of the decade. The national output was 14 at 10 percent above that of 1954(1955 output was estimated at 392 billion dollars). The production of manufactures was about 40 percent more than it had 15 in the years immediately following World War I . The country's business spent about 30 billion dollars for new factories and machinery. National income 16 for spending was almost a third greater than it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day, or about twenty-five million dollars every hour, all round the 17 . Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them. Only agriculture 18 that it was not sharing in the boom. To some observers this was a sad reflection of the mid-1920's. As farmers' share of their products 19 , marketing costs rose. But there were, among the observers of the national economy, a few who were not as confident as the majority.

There may still be a trillion barrels of recoverable oil in the Middle East. But the oil crisis of 1974 has 11 to renewed interest in coal and to a search for12 sources of energy. Solar, geothermal, and nuclear energy will play a large role in the years to come.Solar energy is available in 13 forms. Buildings can be heated and cooled by direct use of solar radiation, crops and trees, which are the most efficient converters of sunlight into energy, can be grown for their energy potential, wastes can be burned as 14 , sunlight can be converted into DC (direct current) electricity, electric power can be 15 from the sun-warmed surface waters of the ocean, and lastly, solar radiation can be converted into heat that will drive electric power generators. Serious problems still remain as to 16 and storage of solar energy.Geothermal energy is the energy contained within the earth. Heat is abundantly available deep in the earth's core and is constantly being produced. However, this heat is usually located at too deep a level for 17 exploitation. In short, very little is known on the use of geothermal energy, and it has 18 been exploited.Nuclear energy is produced in nuclear power plants. At these plants atoms of uranium are split, thus 19masses of energy. Another source of energyunder development is the nuclear fusion of certain atoms of hydrogen. This could eventually 20 natural gas as a source of energy.A. rarelyB. transformationC. fuelD. replaceE. ledF. alternativeG. commercialH. brieflyI. derived J. various K. relieving L. releasingM. transportation N. financial O. describedUNIT 21Like most parents, geologist Brain Atwater worries about his daughter's safety. But these days, he has an unusual concern; The public school she 11 in Seattle has unreinforced brick walls, a 12 being easy to collapse during earthquakes. The same 13 of walls crushed hundreds of thousands of people during the 1976 Tangshan quake in China.A decade ago, Atwater would have paid little notice to schoolroom walls. But over the last several years, he and other scientists have found 14 signs that the Pacific Northwest has experienced giant quakes in the distant past and that the area may be headed for a destructive shock in the near future.At a meeting of the American Geophysical Union in December, researchers discussed the 15 uncovered evidence of quake potential in the Pacific Northwest. While some remain unconvinced that huge earthquakes—with magnitudes of 8 or higher—do indeed 16 this region, a growing number consider such shocks a serious possibility.What's worrisome, they say, is that northwestern cities such as Portland, Seattle and Vancouver have not prepared for earthquakes of this magnitude, which could shake the region's 17 centers with enough force to make the recent San Francisco area damage seem 18 in comparison."I think it's quite true to say that nothing has really been designed with one of these earthquakes in mind," says seismologist Paul Somerville of Woodward.

The possibility of earning a fixed 12 in a factory or office was more attractive than the possibility of staying on the farm and having one's work 13 by frost, storms, or droughts. Furthermore, thedevelopment of agricultural machinery made it possible for fewer people to do the same 14 of work.Thus, at the same time when the industrial revolution made it possible to produce goods more 15 and more quickly in factories, agricultural revolution also took place. Instead of leaving fields empty every third year, farmers began to plant clover or some other crop that would 16 the soil. Instead of using only animal fertilizer, farmers began to use chemical fertilizers to keep the soil• 150 •rich. These methods have enabled French farmers, for example, to get five times as much wheat as was 17 from the same land two centuries ago.In many countries farmers find it more 18 to raise only one crop or one kind of animal. They choose the kind that gives the best results. Then they sell all that they produce, instead of trying to grow a little of everything and consume what they grow. This is a more feasible type of 19 because modern methods and machinery are adapted to specific animals and specific crops. Therefore, it would be too expensive to do all the work by hand, or to buy the 20 needed for several different kinds of farming.A. salary E. deserted I. equivalent M. destroyedB. freely F. operation J. enrich N. certainC. profitable G.amount K. fruitful O. cheaplyD. obtained H. payment L. equipmentUnit Twenty-ThreePassage 2The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and fill it to the level of a free surface. A gas forms no free surface but tends to diffuse throughout the 11 available; it must therefore be kept in a closed container or held by a gravitational field, as in the 12 of a planet's atmosphere. The distinction was a 13 feature of early theories describing the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be "dissolved" in a vapor without losing its identity, and another theory 14 that the two phases are made up of different kinds of molecules. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in 15 They are both forms of matter that have no 16 structure, and they both flow readily.The fundamental similarity of liquids and gases becomes clearly apparent when the temperature and pressure are 17 somewhat. Suppose a closed container 18 filled with a liquid is heated. The liquid expands, or in other words becomes less dense; some of it evaporates. In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are 19 to it. The combination of temperature and pressure at which the densities become 20is called the critical point.A. addedB. caseC. prominentD. heldE. equalF. partiallyG. exampleH. previous' I. space J, lifted K. permanent L. particularlyM. extended N. raised 0. commonUnit Twenty-FourPassage 2Scientists at Sussex University appear to be on the way to 11 how the mosquito, carrier of diseases such as malaria and yellow fever, homes in on its target. The problem is that they have found that the best way to avoid being bitten is: stop breathing, stop sweating, and keep down the temperature of your immediate surroundings. 12 the first suggestion is impossible and the others very difficult.Scientists have found that there are three 13 stages in a mosquito's assault. Stage one is at fifty feet away, when the insect first smells a man or a animal to 14 . Stage two is thought to come into operation about twenty-five feet from the target, when the insect becomes guided by the carbon dioxide breathed out by the intended victim. Stage three is when the mosquito is only a matter of inches from its 15 the warmth and moisture given off by the victim is the final clue.The researchers then * 16 how repellents interfere with its three-stage attack. They found repellents act more subtly than by just giving off a nasty smell. A Canadian researcher says that repellents appear to 17 mosquitoes first when it is following the carbon dioxide and second during the final approach, where the warmth and moisture are the insect's 18 . Air pervaded by one of the many chemical repellents stops the mosquito reacting to the victim's carbon dioxide, and the repellent seems to affect the tiny hairs with which the insect senses moisture in the air. The sensors are blocked so that the 19 does not know whether it is flying through a moist current, orthe sensors are made to send the 20 signals.。
