PART V READING COMPREHENSION [25 MIN]In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer.TEXT AWe can begin our discussion of "population as global issue" with what most persons mean when they discuss "the population problem": too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ the analogy that likened demographic growth to "a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes."To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 BC.till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2000 there will be 6.2 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world's population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.1.Which of the following demographic growth pattern is most suitable for the long thin powder fuse analogy?A.A virtually stable or slightly decreasing period and then a sudden explosion of population.B.A slow growth for a long time and then a period of rapid, dramatic increase.C.Too many people on earth and a few rapid increase in the number added each year.D.A long period when death rates exceeds birthrates and then a short period with higher fertility and lowermortality.2.During the first period of demographic history, societies were often in danger of extinction because .A.only one in ten persons could live past 40.B.there was higher mortality than fertility in most places.C.it was too dangerous to have babies due to the poor conditions.D.our ancestors had little enthusiasm for more children.3.Which statement is true about population increase?A.There might be an increase of 2.2 billion persons from now to the year 2000.B.About 50,000 babies are born every six hours at present.C.Between 8000 BC and the present, the population increase is about 80,000,000 persons each year.D.The population increased faster between 8000BC and 1650 than between 1650 and the present.4.The author of the passage intends to .A.warn people against the population explosion in the near future.pare the demographic growth pattern in the past with that after 1650.C.find out the cause for rapid increase in population in recent years.D.present us a clear and complete picture of the demographic growth.5.The word "demographic" in the first paragraph means .A.statistics of human.B.surroundings study.C.accumulation of human.D.development of human.TEXT BChinese Americans today have higher incomes than Americans in general and higher occupational status. The Chinese have risen to this position despite some of the harshest discrimination and violence faced by any immigrants to the United States in the history of this country. Long confined to a narrow range of occupations they succeeded in those occupations and then spread out into other areas in later years, when opportunities finally opened up for them. Today much of the Chinese prosperity is due to the simple fact that they work more and have more (usually better) education than others. Almost one out of five Chinese families has three or more income earners compared to one out of thirteen for Puerto Ricans, one out of ten among American Indians, and one out of eight among Whites. When the Chinese advantages in working and educational are held constant, they have no advantage over other Americans. That is in a Chinese Family with a given number of people working and with a given amount of education by the head of the family, the income is not only about average for such families, and offer a little less than average.While Chinese Americans as a group are prosperous and well-educated Chinatowns are pockets of poverty, and illiteracy is much higher among the Chinese than among Americans in general. Those paradoxes are due to sharp internal differences. Descendants of the Chinese Americans who emigrated long ago from Toishan Province have maintained Chinese values and have added acculturation to American society with remarkable success. More recent Hong Kong Chinese are from more diverse cultural origins, and acquired western values and styles in Hong Kong, without having acquired the skills to proper and support those aspirations in the American economy. Foreign-born Chinese men in the United States are one-fourth lower incomes than native-born Chinese even though the foreign-born have been in the United States an average of seventeen years. While the older Hong Kong Chinese work tenaciously to sustain and advance themselves, the Hong Kong Chinese youths often react with resentment and antisocial behavior, including terrorism and murder. The need to maintain tourism in Chinatown causes the Chinese leaders to mute or downplay these problems as much as possible.6.According to the passage, today, Chinese Americans owe their prosperity to .A.their diligence and better education than others.B.their support of American government.C.their fight against discriminations.D.advantages in working only.7.The passage is mainly concerned with .A.chinese Americans today.B.social status of Chinese Americans today.C.incomes and occupational status of Chinese Americans today.D.problems of Chinese Americans today.8.Chinatowns are pockets of poverty, as is probably associated with .A.most descendants of Chinese Americans are rebelling.B.most descendants of Chinese Americans are illiterate.C.sharp internal difference between Chinese coming from different cultural backgrounds.D.only a few Chinese Americans are rich.9.Which of the following statements is not true according to this articleA.As part of the minority, Chinese Americans are still experiencing discrimination in American today.B.Nowadays, Chinese Americans are working in wider fields.C.Foreign-born Chinese earn lower income than native-born Chinese Americans with the similar advantagesin the U.S.D.None of the above.10.According to the author, which of the following can best describe the older Hong Kong Chinese and theyoungerA.Tenacious; rebellion.B.Conservative; open-minded.C.Out-of-date; fashionable.D.Obedient; disobedient.TEXT CA controversy erupted in the scientific community in early 1998 over the use of DNA (deoxyribonucleic acid ) fingerprinting in criminal investigations. DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a pattern seen in their DNA, the molecule of which genes are made. DNA is present in every cell of the body except red blood cells. DNA fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. However, it is in the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to trove guilt, not just establish innocence. When used in criminal investigations, a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime. A match between the two DNA samples can be used as evidence to convict a suspect.The controversy in 1998 stemmed form a report published in December 1991 by population geneticists Richard C. Lewontin of Harvard University in Cambridge, Mass., and Daniel L. Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone. In particular, they argued that the current method cannot properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group. Lewontin and Hartl called for better surveys of DNA patterns methods are adequate.In response to their criticisms, population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K.Kidd of Yale University in New Haven, Conn., argued that enough data are already available to show that the methods currently being used are adequate. In January 1998, however, the federal Bureau of Investigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples form various ethnic groups in an attempt to resolve some of these questions. And, in April, a National Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories.11.efore DNA fingerprinting is used, suspects .A.would have to leave their fingerprints for further investigationsB.would have to submit evidence for their innocenceC.could easily escape conviction of guiltD.cold be convicted of guilt as well12.DNA fingerprinting can be unreliable when .A.the methods used for blood- cell calculation are not accurateB.two different individuals of the same ethnic group may have the same DNA fingerprinting patternC.a match is by chance left with fingerprints that happen to belong to two different individualsD.two different individuals leave two DNA samples.13.To geneticists like Lewontin and Hartl, the current method .A.is not so convincing as to exclude the likelihood that two DNA samples can never come from twoindividualsB.is arguable because two individuals of the same ethnic group are likely to have the same DNA pattern.C.Is not based on adequate scientific theory of geneticsD.Is theoretically contradictory to what they have been studying14.The attitude of the Federal Bereau of Investigation shows that .A.enough data are yet to be collected form various ethnic groups to confirm the unlikelihood of two DNAsamples coming from two individual membersB.enough data of DNA samples should be collected to confirm that only DNA samples form the same personcan matchC.enough data are yet to be collected from various ethnic groups to determine the likelihood of two differentDNA samples coming form the same personD.additional samples from various ethnic groups should be collected to determine that two DNA samples areunlikely to come from the same person15.National Academy of Sciences holds the stance that .A.DNA testing should be systematizedB.Only authorized laboratories can conduct DNA testingC.The academy only is authorized to work out standards for testingD.The academy has the right to accredit laboratories for DNA testingTEXT DMost of us are taught to pay attention to what is said—the words. Words do provide us with some information, but meanings are derived from so many other sources that it would hinder our effectiveness as a partner to a relationship to rely too heavily on words alone. Words are used to describe only a small part of the many ideas we associate with any given message. Sometimes we can gain insight into some of those associations if we listen for more than words. We don't always say what we mean or mean what we say. Sometimes our words don't mean anything except " I'm letting off some steam. I don't really want you to pay close attention to what I'm saying. Just pay attention to what I'm feeling." Mostly we mean several things at once. A person wanting to purchase a house says to the current owner, "This step has to be fixed before I'll buy." The owner says, " It's been like that for years." Actually, the step hasn't been like that for years, but the unspoken message is: " I don't want to fix it. We put up with it. Why can't you?" The search for a more expansive view of meaning can be developed of examining a message in terms of who said it, when it occurred, the related conditions or situation, and how it was said.When a message occurs can also reveal associated meaning. Let us assume two couples do exactly the same amount of kissing and arguing. But one couple always kisses after an argument and the other couple always argues after a kiss. The ordering of the behaviors may mean a great deal more than the frequency of the behavior.A friend's unusually docile behavior may only be understood by noting that it was preceded by situations that required an abnormal amount of assertiveness. Some responses may be directly linked to a developing pattern of responses and defy logic. For example, a person who says "No!" to a serials of charges like "You're dumb," "You're lazy," and "You're dishonest," may also say "No!" and try to justify his or her response if the next statement is "And you're good looking."We would do well to listen for how messages are presented. The words, "If sure has been nice to have you over," can be said with emphasis and excitement or ritualistically. The phrase can be said once or repeated several times. And the meanings we associate with the phrase will change accordingly. Sometimes if we say something infrequently it assumes more importance; sometimes the more we say something the less importance it assumes.16.Effective communication is rendered possible between two conversing partners, if .A.they use proper words to carry their ideas.B.they both speak truly of their own feelings.C.they try to understand each other's ideas beyond words.D.they are capable of associating meaning with their words.17."I'm letting off some steam" in paragraph 1 means .A.I'm just calling your attention.B.I'm just kidding.C.I'm just saying the opposite.D.I'm just giving off some sound.18.The house-owner's example shows that he actually means .A.the step has been like that for years.B.he doesn't think it necessary to fix the step.C.the condition of the step is only a minor fault.D.the cost involved in the fixing should be shared.19.Some responses and behaviors may appear very illogical, but are justifiable if .A.linked to an abnormal amount of assertiveness.B.seen as one's habitual pattern of behavior.C.taken as part of an ordering sequence.D.expressed to a series of charges.20.The word "ritualistically" in the last paragraph equals something done .A.without true intention.B.light-heartedly.C.in a way of ceremony.D.with less emphasis.答案：1-5 ABADA 6-10 ACCCA 11-15 CBABB 16-20 DBABC。

以下是店铺为大家搜索整理大学英语专业四级试题阅读理解模拟测试，希望对正在关注的您有所帮助!Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood.Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily. Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.?1. The stone chip is thought to be the most important tool because it ______.A. was one of the first toolsB. developed human capabilities?C. led to the invention of machinesD. was crucial to the development of mankind2.

大学英语四级阅读模拟题及答案阅读1空调的危害Although many of us may feel air-conditioners bring relief from hot,humid or polluted outside air,they pose many potential health hazards.Much research has looked at how the movement of air inside a closed environment---such as an office building---can spread disease or expose people in the building to harmful chemicals.One of the more widely publicized dangers is that of Legionnaire’s disease,which was first recognized inthe1970s.This was found to have affected people in buildings with air-conditioning systems in which warmair pumped out of the system’cooling towers was somehow sucked back into the air intake(通风口),in mostcases due to poor design.The warm air,filled with bacteria,was combined with cooled,conditioned air andwas then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.Large air-conditioning systems add water to the air they circulate by means of humidifiers(湿度调节器).Inolder systems,the water used for this process is kept in special reservoirs,the bottoms of which providebreeding grounds for bacteria which can find their way into the ventilation (通风)system.The risk to human health from this situation has been highlighted by the fact that the immune systems(免疫系统)of approximately half of workers in air-conditioned office buildings have developed the ability to fight off the organisms found at the bottom of system reservoirs. But chemicals called“biocides”are added to reservoirs to make them germ-free,and they are dangerous in their own right in sufficient quantities,as they often contain compounds strongly linked to cancers.Finally,it should be pointed out that the artificial climatic environment created byair-conditioners canalso affect us.In a natural environment,whether indoor or outdoor,there are small variations in temperature and humidity.Indeed,the human body has long been accustomed to these normal changes.In an air-conditioned living or working environment,however,body temperatures remain well under37℃,our normal temperature.This leads to a weakened immune system and thus greater exposure to diseases such as colds and flu.练习题：Choose correct answers to the question:1.What do we know about Legionnaire's disease from the passage?A.It was the most widely concerned office hazard.B.It can affect people both inside and outside the building.C.It happens only in air-conditioned office buildings.D.It does not develop in well-designed buildings.2.In the old air-conditioned systems,bacteria first develop______.A.in the reservoirsB.in the ventilation systemc.in the humidifiersD.in the air intake3.The fact that about half of workers developed the ability to fight off the bacteria may__.A.relieve people’s worry about the danger caused by the bacteriaB.help people find an effective way to get rid of the bacteriaC.reflect the serious danger brought by the bacteriaD.cause serious disease such as cancers to people4.The author most probably wants the readers to treat biocides with an attitude of_.A.cautionB.trustC.enthusiasmD.criticism5.The last paragraph implies that our immune system can be weakened when_•A.we live in an artificial climatic environmentB.there are variations in temperature and humidityC.our body temperatures often remain not high enoughD.we are often exposed to diseases such as colds and flu答案解析：1.[B]事实细节题。

听力（略）Part II Reading ComprehensionDirections: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D), and you should decide which is the best choice. (40 points)Passage 1Questions 26 to 30 are based on the following passage:The United States is full of automobiles. There are still many families without cars, but some families have two or even more. However, cars are used for more than pleasure. They are necessary part of life.Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. Farmers have to drive into the city in order to get supplies. Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile from the school. When the children are too young to walk that far, their mothers take turns driving them to school. One mother drives on Mondays, taking her own children and neighbors' children as well. Another drives on Tuesdays, another on Wednesdays, and so on. This is called forming a car pool. Men also form car pools, with three or four men taking turns driving to the place where they all work.More car pools should be formed in order to put fewer automobiles on the road and to use less gasoline. Parking is a great problem, and so is the traffic in and around cities. Too many cars are being driven. Something will have to be done about the use of cars.26. Many families in the U.S. own cars because ________.A) cars are a source of pleasure for themB) they need a car to form a car poolC) they live more than a mile away from the schoolD) cars form necessary part in their life27. Which of the following groups is NOT mentioned though they certainly drive cars?A) Office workers.B) Police and mail carriers.C) Salesmen and farmers.D) Factory workers.28. Paragraph 3 suggests that in the United States ________.A) children have to walk to schoolB) school buses take all the children to schoolC) mothers drive children to schoolD) families usually live within a mile from the school29. "A car pool" most probably means ________.A) a number of people sharing the use of a carB) a place for parking carsC) a group of tourists driving alternativelyD) a place for learning to drive30. What is the author's advice about the use of cars?A) To provide larger parking spaces.B) To build better roads.C) To produce fewer automobiles.D) To form more car pools.Passage 2Question 31 to 35 are based on the following passage:Recent fires have destroyed much of Indonesian forests and pose the latest threat to the survival of the endangered orangutans（红毛猿）. Thirty orangutans fleeing their burning forest home have been killed by villagers, who see the animals as crop raiders. Orangutan mothers have been killed so that their young can be captured and sold into the illegal wildlife pet trade. Orangutan experts continue to receive orangutan infants whose mothers have been killed while searching for food in plantations and fields.The fires, caused by drought and coupled with fire-setting methods to clear forests, have destroyed more than two million acres. When fire gets into the rainforests' layer of dry peat (partly decayed plant material which covers the soil), it can burn slowly off and on for months or years after the original fire. These fires continue until heavy rainfall soaks the peat through and through. Orangutans once numbered in the hundreds of thousands, but their population has dropped to roughly 25 000 due to fire, the destruction of forests from felling trees for timber and agriculture, and losses linked to the live-animal trade. Before the fires, only 40 percent of the orangutans' original habitat remained, and now, their habitat has become even smaller.31. What can be the best title for this passage?A) Fires Drive Orangutans to Danger.B) Orangutans Are Precious Animals.C) Fires in Indonesia Keep on Flaming.D) Orangutans Endanger the Crops of Indonesia.32. Which of the following is true about villagers?A) They set fire in order to kill orangutans for food.B) They are ignorant of wild life pets trade.C) They dislike orangutans because they destroy crops.D) They continue to receive orangutans infants.33. According to this passage, fires in Indonesia ________.A) will not end until it starts to rainB) will be eventually put out by human effortC) will die out when the winds stop blowingD) will only stop when the peat is totally wet34. Some people buy orangutans because ________.A) they want to save orangutansB) they want to keep orangutans as petsC) they want to build new homes for orangutansD) they want to take care of orangutan infants35. Which of the following is NOT a reason for the decreasing of orangutans in Indonesia?A) The forests have been burned to make land for agriculture.B) Most of orangutans' forests have been destroyed.C) Mother orangutans have been caught and sold in pet-animal market.D) Trees have been cut down for human profits.Passage 3Question 36 to 40 are based on the following passage:Don't try kicking the tires on a very modern and strange car developed by students at Coventry University. Not only does the car have no tires, it has no steering wheel, either.The Coventry Concept Car, as it is called is a completely new design that looks more like a snail（蜗牛）than an automobile. No working model, or functional form of the vehicle exists yet, but its designers recently introduced a life-sized model and explained how a real one would work. Electric motors would move rapidly undulating pad（形成波浪状气垫）underneath the car; moving the vehicle in any direction at speeds up to 480 km per hour. The motion would be a much faster way of crawling ? the way snails move. (Muscles in the bottom of a snail's flat foot contract （收缩）in waves that push the snail along the ground.)Steering of the snail car would be handled automatically by an onboard computer, which would receive signals from orbiting satellites. Those signals would help guide the snail car along a preprogrammed route.Even the car's color could be computer-controlled, the student designer suggested. Instead of a painted out appearance, the snail car would sport an electronically sensitive film that changes color according to its surroundings.36. The Coventry Concept Car is designed mainly based on ________.A) the appearance of a snailB) the movement of a snailC) the life-size of a snailD) the behavior of a snail37.

Which of the following might be the best title for the passage?A) A Car at a Speed of a SnailB) A Computer-Controlled Electronic VehicleC) A Car Without Tires and Steering WheelD) A Car with No Functional FormPassage 4Question 41 to 45 are based on the following passage:Have you ever been afraid to talk back when you were treated unfairly? 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 themselves（坚持自己的权利）. Dr. Alberti, author of Stand Up, Speak Out, and Talk Back, thinks it's because their self-respect is low. "Our whole set-up is designed to make people distrust themselves," says Alberti. "There's always a 'superior' around: a parent, a teacher, a boss who 'knows better'."But Alberti and other scientists are doing something to help those people assert themselves. They offer "Assertiveness Training" courses ? AT for short. In the AT course 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 aggressive without hurting other people.In one way, learning to speak out is to overcome fear. A group taking an AT course will help the timid person to lose his fear. But AT uses an even stronger motive ? 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 doubt your own good sense. You go by the other person's label. But, why should you? AT says you can get to feel good about yourself. And once you do, you can learn to speak out.41. The problem the writer talks about is that _______.A) some people buy things they don't wantB) some people are afraid of arguing for themselvesC) there are too many "superiors" around usD) there is too much pressure from our society42.

The set-up of our society often _______.A) makes people distrust themselvesB) makes things more favorable for "superiors"C) keeps people from knowing as much as their "superiors"D) helps people to learn to speak up for their rights44. A T is one solution to the problem in this passage, but one thing AT doesn't promote is to help people ________.A) to share their feelingsB) to have a right to be oneselfC) to overcome their fear before othersD) to be more aggressive45. The title for this passage could be ________.A) Assertiveness TrainingB) Loss of Self-respectC) The Importance of Human RightsD) Share Your Feelings with OthersPart III Vocabulary and StructureDirections: There are 20 incomplete sentences in this part.

(67) This marketing plan involves two parts: you have to figure out who the market is; and you have to make the product or service known to that market. These two work together.It is a rare case in marketing when a product has appeal to everyone regardless of sex, age, income level or special interests. (68) The more typical case is that a product will appeal to a limited group of people who are willing to put down their hard-earned dollars to buy what you have to sell.(69) The basic question to keep in mind as you develop your marketing plan is: Who would want to buy the type of product I make and how can I develop it to be saleable to these special people? Once you define your market, you often have to modify your product to fit that market. Sometimes the answer to this question is clear and logical. Often, however, a business person has to do some research and experimentation to find the answer.

大学英语四级阅读模拟练习题附答案
大学英语四级阅读模拟练习题附答案It came as something of a surprise when Diana, Princess of Wales, made a trip to Angola in 1997, to support the Red Crosss campaign for a total ban on all anti-personnel landmines. Within hours of arriving in Angola, television screens around the World were filled with images of her comforting victims injured in explosions caused by landmines. I knew the statistics, she said. But putting a face to those figures brought the reality home to me; like When I met Sandra, a 13-year-old girl who had lost her leg, and people like her.The Princess concluded, with a simple message: We must stop landmines. And she used every opportunity during her visit to repeat this message.But, back in London, her views were not shared by some members of the British government, which refused to support a ban on these weapons. Angry politicians launched an, attack on the Princess in the press. They described her as very ill-informed and a loose cannon (乱放炮的人).The Princess responded by brushing aside the criticisms: Thisis a distraction (干扰) we do not need. All Im trying to do is help. Opposition parties, the media and the Public immediately voiced their support for the Princess. To make matters worse for the government, it soon emerged that the Princesss trip had been approved by the Foreign Office, and that she was in fact very well-informed about both the situation in Angola and the British governments policy regarding landmines. The result was a severe embarrassment for the government.To try and limit the damage, the Foreign Secretary, Malcolm Rifkind, claimed that the Princesss views on landmines were not very different from government policy, and that it was working towards a worldwide ban. The Defense Secretary, Michael Portillo, claimed the matter was a misinterpretation or misunderstanding.For the Princess, the trip to this war-torn country was an excellent opportunity to use her popularity to show the world how much destruction and suffering landmines can cause. She said that the experience had also given her the Chance to get closer to people and their problems.26. Princess Diana paid a visit to Angola in 1997 ________.A) to voice her support for a total ban of landminesB) to clarify the British governments stand on landminesC) to investigate the sufferings of landmine victims thereD) to establish her image as a friend of landmine victims27. What did Diana mean when she said ... putting a face to those figures brought the reality home to me (Line 5, Para. 1)A) She just couldnt bear to meet the landmine victims face to face.B) The actual situation in Angola made her feel like going back home.C) Meeting the landmine victims in person made her believe the statistics.D) Seeing the pain of the victims made her realize the seriousness of the situation.28. Some members of the British government criticized Diana because ________.A) she was ill-informed of the governments policyB) they were actually opposed to banning landminesC) she had not consulted the government before the visitD) they believed that she had misinterpreted the situation in Angola29.

What did Princess Diana think of her visit to AngolaA) It had caused embarrassment to the British government.B) It had brought her closer to the ordinary people.C) It had greatly promoted her popularity.D) It had affected her relations with the British government.26. A 27. D 28. B 29.A 30. BScratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being ableto quickly tell the two apart. Thats because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three virusesflu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell wheninfants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症)，a rare but serious condition of the liver and central nervous system.There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.11. According to the author, knowing the cause of the misery will help ________.A) shorten the duration of the illnessB) the patient buy medicine over the counterC) the patient obtain cheaper prescription drugsD) prevent people from catching colds and the flu12. We learn from the passage that ________.A) one doesnt need to take any medicine if he has a cold or the fluB) aspirin should not be included in over-the-counter medicinesfor the fluC) delayed treatment of the flu will harm the liver and central nervous systemD) over-the-counter drugs can be taken to ease the misery caused by a cold or the flu13. According to the passage, to combat the flu effectively, ________.A) one should identify the virus which causes itB) one should consult a doctor as soon as possibleC) one should take medicine upon catching the diseaseD) one should remain alert when the disease is spreading14. Which of the following symptoms will distinguish the flu from a coldA) A stuffy nose.B) A high temperature.C) A sore throat.D) A dry cough15. If children have flu-like symptoms, their parents ________.A) are advised not to give them aspirinB) should watch out for signs of Reye syndromeC) are encouraged to take them to hospital for vaccinationD) should prevent them from mixing with people running a fever11. A 12. D 13. C 14.B 15. A。

For questions 8-10, complete the sentences with the information given in the passage.Main Energies for the BodyA balanced diet is one that provides an adequate intake of energy and nutrients for maintenance of the body and therefore good health. A diet can easily be adequate for normal bodily functioning, yet may not be a balanced diet.CarbohydratesCarbohydrates are a rapid source of energy, they are the body's fuel. The bulk of a balanced diet should be made from carbohydrates. If eaten in an excess of the dietary requirements carbohydrates are easily stored as fats in the cells, although carbohydrate is the first source of energy in the body. An average adult requires about 12,000kJ of energy a day, most of this is supplied by the respiration of carbohydrates in the cells.Carbohydrates are used principally as a respiratory substrates, i.e. to be oxidized to release energy for active transport, macromolecule synthesis, cell division and muscle contraction. Carbohydrates are digested in the duodenum and ileum and absorbed as glucose into cells. Sources of carbohydrates such as starch are rice, potatoes, wheat and other cereals. Sugars are also carbohydrates, sources of sugars are refined sugar - sucrose, which is a food sweetener and preservative and fruit sugars - fructose. If the diet lacks carbohydrate stores of fat are mobilized and used as an energy source.ProteinsProtein is not a direct source of energy in the body, it is used primarily for growth and repair of body tissues while remaining an energy source as a last resort. Proteins fulfill a wide variety of roles in the body. They are broken down in the stomach and intestines to amino acids which are then absorbed. The body can only form 8 amino acids to build proteins from, the diet must provide Essential Amino Acids (EAAs) which are synthesized into proteins which can be structural, i.e. collagen in bone, keratin in hair, myosin and actinin muscle; metabolic enzymes, hemoglobin, protective antibodies and communicative hormones.Sources of protein include meat, fish, eggs and pulses. The diet needs to provide 8 EAAs as the body is unable to synthesis proteins without these molecules. 2 other amino acids are synthesized from EAAs so if the diet lacks the original EAAs these other two will not be present either. Phenylalanine is converted to tyrosine and methionine is converted to cysteine. Cells draw upon a pool of amino acids for protein synthesis which either come from dietary protein digested and absorbed in the gut and the breakdown of body protein such as muscle. However, unlike fats and carbohydrates there is no store of amino acids for cells to draw on, any amino acid in excess of immediate bodily requirements is broken down into urea and excreted. It is therefore important to maintain the dietary intake of protein everyday. If the body lacks protein, muscle wasting occurs as muscle is broken down.If protein is lacked in a diet a person develops kwashiorkor which is caused when high levels of carbohydrates are eaten to overcome the lack of protein in the diet. One symptom of kwashiorkor is the abnormal collection of fluid around the abdomen due to the lack of protein in the blood. The body cannot retain water by osmosis and fluid accumulates in tissues causing them to become waterlogged.Vitamin CategoriesVitamins cannot be synthesized by the body so must be supplied by diet. Vitamins have no common structure or function but are essential in small amounts for the body to be able to utilize other dietary components efficiently.Vitamins fall into two categories, fat soluble vitamins such as vitamin A, D, E and K which are ingested with fatty foods and water soluble vitamins such as the B group vitamins and vitamin C. Vitamins are known as micronutrients because only small quantities are required for a healthy diet, in fact fat soluble vitamins can be toxic in high concentrations, for example the body stores vitamin A, or retinol, in the liver as it is toxic if kept in high concentrations in the blood stream, a dose of more than 3300mg of vitamin A can be considered toxic. Water soluble vitamins such as vitamin C and B groups vitamins can be excreted in the urine if in excess in the diet.Vitamins AVitamin A is essential to the proper functioning of the retina in the eye and the epithelial tissues. A lack of vitamin A results in dry, rough skin, inflammation of the eyes, a drying or scarring of the cornea - xerophthalmia, which occurs when the secretion of lubricating tears is stopped, the eyelids become swollen and sticky with pus. Mucous surfaces of the eye may become eroded allowing infection to set in, leading to ulceration and destruction of the cornea. Night blindness - an inability to see in dim light can also occur. Rod cells in the retina of the eye detect light of low intensity, they convert vitamin A into a pigment, rhodopsin, which is bleached when light enters the eye. Rod cellsresynthesis rhodopsin, but if there is a deficiency of the vitamin, rod cells can no longer function and the result is night blindness. Epithelial cells use retinol to make retinoic acid, an intracellular messenger used in cell differentiation and growth. Without retinoic acid epithelial cells are not maintained properly and the body becomes susceptible to infections, particularly measles and infections of the respiratory system and gut.Xenophthalmia is common among children who's diets consist of mainly cereals with little meat or fresh vegetables, this is common in Indonesia, Bangladesh, India and the Philippines.Vitamins DVitamin D, or calciferol, is another fat soluble steroid vitamin which functions to stimulate calcium uptake from the gut and its deposition in bone. vitamin D acts as a hormone when converted by enzymes in the gut and liver into an active form of "active vitamin D", which stimulates epithelial cells in the intestine to absorb calcium. vitamin D is therefore essential in growing children's diets to enable the growth of strong bones. Without adequate amounts of vitamin D children can develop rickets, which is the deformation of the legs caused when they lack calcium to strengthen the bones. In adults a lack of vitamin D in the diet can lead to osteomalacia, a progressive softening of the bones which can make them highly susceptible to fracture.Vitamin D is made by the body when exposed to sunlight and is stored in the muscles, however, if the skin is rarely exposed to the sunlight or is dark little vitamin D is produced. Foods such as eggs and oily fish are all rich in vitamin D.Vitamins KVitamin K, phylloquinone, is found in dark green leafy vegetables such as spinach and kale. It is a fat soluble vitamin which is involved in the clotting process of blood. In the intestines bacteria synthesize a number of important clotting factors which need vitamin K. Without vitamin K cuts can fail to heal and internal bleeding can occur.Vitamins CVitamin C is a water soluble vitamin, known chemically as ascorbic acid. It is found in citrus fruits such as oranges and lemons, and also in potatoes and tomatoes. The main function of vitamin C is the formation of connective tissues such as collagen. It is also known to be an antioxidant which helps to remove toxins and aids the immune system. A lack of vitamin C leads to Scurvy, a condition experienced by sailors on long journeys when they did not have fruit in their diets. Scurvy causes painful, bleeding gums. As vitamin C is water soluble, it is not toxic in high doses as it can be excreted in the urine, very high doses can however cause diarrhea.Vitamins BB group vitamins have a wide range of roles acting as co-enzymes in metabolic pathways. They are found in most plant and animal tissues involved in metabolism,therefore foods such as liver, yeast and dairy products are all rich in B group vitamins. Deficiency of B group vitamins include dermatitis, fatigue and malformation of red blood cells.1.

Night blindness is a disease normally caused by lack of __________.A. fat soluble vitaminsB. water soluble vitaminsC. vitamin AD. innate disability7. The main function of vitamin D is to prevent adults from ________.A. the growth of strong bonesB. fractureC. a progressive softening of the bonesD. calcium uptake from the gut8.

And cognitive neuroscientists have discovered that dreams and the rapid eye movement (REM) that happens while you’re dreaming are __49__ to our ability to learn and remember. Dreaming is a “mood regulatory system,” says Rosalind Cartwright, PhD, chairman of the psychology __50__ at Rush University Medical Center in Chicago. She’s found that dreams help people work through the day’s emotional quandaries. “It’s like having a built-in therapist,” says Cartwright. While we sleep, dreams __51__ new emotional experience to old memories, creating plaid-like patterns of old images laid on top of new ones. As she puts it, “You may wake up and think, What was Uncle Harry doing in my dream? I haven’t seen him for 50years. But the old and new images are __52__ related.” It’s the job of the conscious mind to figure out the relationship. In fact, dream emotions can help real therapists treat patients __53__ traumatic (创伤旳) life events. In a new study of 30 recently __54__ adults, Cartwright tracked their dreams over a five-month period, measuring their feelings toward their ex-spouses.

You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.A few years ago a young mother watched her husband diaper (给…换尿布) their firstborn son. “You do not have to be unhappy about it,” she protested. “You can talk to him and smile a little.” The father, who happened to be a psychologist, answered firmly, “He has nothing to say to me, and I have nothing to say to him.”Psychologist now know how wrong that father was. From the moment of birth, a baby has a great deal to say to his parents, and they to him. But a decade or so ago, these experts were describing the newborn as a primitive creature who reacted only by reflex, a helpless victim of its environment without capacity to influence it. And mothers acceptedthe truth. Most thought (and some still do) that a new infant could see only blurry (模糊旳) shadows, that his other senses were undeveloped, and that all he required was nourishment, clean diapers, and a warm bassinet.Today university laboratories across the country are studying newborns in their first month of life. As a result, psychologists now describe the new baby as perceptive, with remarkable learning abilities and an even more remarkable capacity to shape his or her environment including the attitudes and actions of his parents. Some researchers believe that the neonatal period may even be the most significant four weeks in an entire lifetime.Far from being helpless, the newborn knows what he likes and rejects what he doesn’t. He shut out unpleasant sensations by closing his eyes or averting his face. He is a glutton for novelty. He prefers animate things over inanimate and likes people more than anything.When a more nine minutes out, an infant prefers a human face to a head-shaped outline. He makes the choice despite the fact that, with delivery room attendants masked and gowned, he has never seen a human face before. By the time he’s twelve hours old, his entire body moves in precise synchrony (同步发生) to the sound of a human voice, as if he were dancing. A non-human sound, such as a tapping noise, brings no such response.57. The author points out that the father diapering his first-born son was wrong because________.A) he believed the baby was not able to hear himB) he thought the baby didn’t have the power of speechC) he was a psychologist unworthy of his professionD) he thought the baby was not capable of any response58. According to the passage, which of the following is TRUE?A) A new infant can see only blurry shadows.B) A new infant’s senses are undevelopedC) All a new infant requires is nourishment, clean diapers, and a warm bassinet.D) A new infant is actually able to influence his or her environment59. What does the sentence “He is a glutton for novelty” probably mean?A) The newborn is greedy for new food.B) The newborn tends to overeat.C) The newborn always loves things that are new to him.D) The newborn’s appetite is a constant topic in no vels.60. According to the passage, it’s groundless to think that newbornsprefer________.A) a human face to a head-shaped outlineB) animate things to inanimate onesC) human voice to non-human soundsD) nourishment to a warm bassinet61. What is the passage mainly discussing about?A) What people know about newborns.B) How wrong parents are when they handle their babies.C) How much newborns have progressed in about a decade’s time.D) Why the first month of life is the most significant four weeks in a lifetime.Passage TwoQuestions 62 to 66 are based on the following passage.Mobile office is the mutual product of economic，scientific，and social progress.Mobile office has become a solution that provides users with convenient, prompt, safe, reliable, and reasonably priced communications and office faculty anywhere anytime via the support of mobile interconnection platform(MIP)and its applications systems. Using mobile office and WAP technology, people can do their work anywhere anytime, can send and receive data via terminals such as mobile phone, and palm computer, and can surf the Internet.When you leave your office to attend meetings or travel on business，what would happen to your business routine?Of course, faxes and e-mails would be still sent to your fax machine or e-mail box, but you cannot read them and make prompt reaction timely. When your clients need you to make some urgent modifications on your work and you are neither in the office nor carrying relevant documents, what can you do?Maybe you have to say “sorry” to the clients. But, your business will be affected，the clients will be unhappy and disappointed because of your delay，and you will lose a lot of business opportunities.In fact, very frequently, you need to check, reply, distribute, modify, or read some materials when you are not in your office. You must get out of this dilemma. The best solution to normally handle your business anywhere anytime and not to disappoint your clients is to let your office “move” with you. With the development of communications technology, mobile office has become simpler and smaller, and even can be realized via one mobile phone with data communications function. Thus, mobile office has already been put into your pocket, and office mobility has been realized.Mobile office has provided people with convenient, casual working environment, but at the same time it still has some unsatisfactory aspects such as mismatching equipment interface and inadequate battery. Nevertheless, we believe that with technical progress, people can certainly overcome all kinds of difficulties. Mobile office will realize the dream of completely free communication. Users will enjoy more colorful life and better working environment, and users’ living standard, working efficiency, and even enterprises’ production efficiency will certainly be immensely raised.注意：此部分试题在答题卡2上作答62.

When you let your office “move” with you, you __________ .A) will never let your clients downB) you don’t have to stay at office anymoreC) you then find the best way to handle your business anywhere anytimeD) you no longer face the dilemma between work and life65.

大学生英语四级阅读模拟练习题及答案大学生英语四级阅读模拟练习题及答案Of all the ponents of a good night's sleep, dreams seemto be least within our control. Indreams, a window opens into a world where logic is suspended and dead people speak. Acentury ago, Freud formulated his revolutionary theory that dreams were the disguisedshadows of our unconscious desires and fears; by thelate 1970s, neurologists had switched tothinking of them as just "mental noise"-the random byproducts of the neural repair work thatgoes on during sleep. Now researchers suspect that dreams are part of the mind's emotionalthermostat, regulating moods while the brain is "off line." And one leading authority says thatthese intensely powerful mental events can be not only harnessed but actually brought underconscious control, to help us sleep and feel better. "It's your dream," says RosalindCartwright, chair of psychologyat Chicago's Medical Center, "if you don't like it, change it."he link between dreams and emotions shows up among the patients in Cartwright's clinic. Mostpeople seem to have more bad dreams early in the night, progressing toward happier onesbefore awakening, suggesting that they are workingthrough negative feelings generatedduring the day. Becauseour conscious mind is oupied with daily life we don't always thinkabout the emotional significance of the day's events-until, it appears, we begin to dream.And this process need not be left to the unconscious. Cartwright believes one can exerciseconscious control over recurring bad dreams. As soon as you awaken, identify what isupsetting about the dream. Visualizehow you would like itto end instead; the next time itours, try to wake up just enough to control its course. With much practice people can learnto, literally, do it in their sleep.At the end of the day, there's probably little reason to pay attention to our dreams at all unlessthey keep us from sleeping or "we wake up in panic," Cartwright says. Terrorism, economicuncertainties and general feelings of insecurity have increased people's anxiety. Thosesuffering from persistent nightmares should seek help from a therapist. For the rest of us, thebrain has its ways of working through badfeelings.Sleep-or rather dream-on it and you'll feelbetter in the morning.1.By saying that “dreams are part of the mind'semotional thermostat," (Lines 4-5, Para. 1) the researchers mean that .A.we can think logically in the dreams tooB.dreams can be brought under conscious controlC.dreams represent our unconscious desires and fearsD.dreams can help us keep our mood paratively stable2.What did Cartwright find in her clinic?A.Most bad dreams were followed by happier ones.B.Divorced couples usually have more bad dreams.C.One’s dreaming process is related to his emotion.D.People having negative feelings dream more often.3.Cartwright believed with much practice，we can learnto .A.control what dreams to dreamB.sleep well without any dreamsC.wake up in time to stop the bad dreamsD.identify what is upsetting about the dreams4.The author points out that a person who has constant bad dreams shouldA.learn to control his dreamsB.consult a doctorC.sleep and dream on itD.get rid of anxiety first5.The author most probably thinks that controlling dreams is .A.a good practiceB.a new discoveryC.helpful for everyoneD.not essential for everyone1.[D] 词义理解题。
