阅读理解训练（39）‎ Passage 1‎ How many things can you see in the night sky? A lot! On a clearnight you might see the Moon, some planets, and thousands of sparkling stars.‎ ‎ You can see even more with a telescope. And with bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more detail.‎ ‎ But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year.‎ ‎ That's because they're invisible. They're the mysterious dead stars called black holes.‎ ‎ You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years.‎ ‎ As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die.‎ ‎ As the star cools, the outer layers of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe.‎ ‎ Imagine if the Earth were crushed until it was the size of a tiny marble. That's how tightly this dead star, a black hole, is packed. What pulls the star in toward its center with such power? It's the same force that pulls you down when you jump--the force called gravity. A black hole is so tightly packed that its gravity sucks in everything--even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness.‎ ‎ So next time you stare up at the night sky, remember: there's more in the Sky than we can see! Scattered in the silent darkness are black holes--the great mystery of space.‎ ‎1. According to the article, what causes a star to die?‎ ‎ A. As its gases run out, it cools down. B. It has a collision with other stars.‎ C. It can only live for about a million years. ‎ D. As it gets hotter and hotter, it explodes.‎ ‎2. Which of the following statements is NOT true?‎ ‎ A. Black holes are dead stars.‎ ‎ B. Black holes have gravity.‎ ‎ C. Black holes are invisible.‎ ‎ D. There is nothing as mysterious as a black hole.‎ ‎3. W. hat happens AFTER a star dies?‎ ‎ A. It becomes invisible. B. It fails to Earth.‎ ‎ C. It burns up all of its gases. D. It becomes brighter and easier to see.‎ ‎4. Why can't you see light when you look at a black hole?‎ ‎ A. Because most black holes are so far away.‎ ‎ B. Because the gravity of a black hole is so strong that it sucks the light inward.‎ ‎ C. Because as the star's gases burn, it stops giving off heat and light.‎ ‎ D. Because as a star cools, its outer layers pull in toward its center. ‎ 答案 ADAB Passage 2‎ Every day from the time we wake up until the time we go to bed, we are bombarded with information from all sides, from TV, radio, newspapers and books; from family, friends, and colleagues. As a new cable television subscriber, I am absolutely amazed at the quantity and varying levels of information quality on cable television. Including the networks, there are eight TV "news" organizations vying to provide us with all the information we can possibly absorb. Newspaper, magazines, books, radio, the Internet, email, snail mail, and the telephone all compete for our attention and our minds. At the office conversations around the water cooler and coffee maker serve to spread even more items of information. 　　There is valuable information out there about the world we live in, on topics as varied as health, safety, traffic, nutrition, business, finance, philosophy, nature, science, weather, history and the human condition. There is also a large amount of misleading and outright false information, not just on controversial subjects such as politics and religion but on any topic one can think of, including all of the topics mentioned above. 　　With all this information coming at us from all directions, how does one sift through it all to sort out the facts from the fiction, the truth from the lies, the more important from the less important? Should we turn off the TV, cancel our newspaper subscriptions, disconnect our phones and modems to become information "hermits"? Probably not. 　　A better method of sifting through the information wave without being overwhelmed and confused is to become a skeptical inquirer-or skeptic-with regard to the surrounding world. By "skeptic"-I do not mean a cynic-a person who rejects new ideas simply because they are new. A skeptic is one who questions the validity of a particular claim by calling for evidence to prove or disprove it. Skepticism is a method, not a position. It is a provisional approach to all factual claims. In terms of processing information, a skeptic needs to be able to grasp reality and acquire knowledge about the environment that agrees with reason, logic, and evidence. In other words, as skeptics, when we hear a claim that may or may not be fantastic, we should say, "That's nice, prove it."‎ ‎5．The writer implies that if we want to make some judgments about some information, the first thing that we should do is to . A. ask for the information B. cut off all channels of information C. receive and go through the information D. become information "hermits"‎ ‎6. What does the author say is the more reasonable approach to processing the information ‎ wave? A. A skeptical approach. B. A subjective approach. ‎ C. A cynical approach. D. A philosophical approach.‎ ‎7. What can we conclude from the difference between a skeptic and a cynic? 　　 A. Skeptics are reasonable but cynics are too optimistic. 　　 B. Skeptics are reasonable but cynics are too pessimistic(opposite of optimistic). 　　 C. Skeptics take a position but cynics are extreme in their attitude. 　　 D. Skeptics reject all new ideas but cynics only reject some of them. 　 8. When faced with an incredible or fantastic claim, what shall we do according to the author? 　　 A. Ask questions and look for proof. B. Ignore the information and its source. 　　 C. Change the subject immediately. ‎ D. Try to consult an expert who knows the truth.‎ 答案 CABA Passage 3‎ China’s government has been trying all measures to reduce pollution in the past few years. Now people can enjoy a fresh environment everywhere. The following two graphs are adopted from the column of “City Information” on the webpage of Beijing Review.‎ Graph 1: Olympic Cities Air Quality Report City Date API Major Pollutant Air Quality Degree Quality Condition Beijing Sep. 8‎ ‎37‎ N/A Ⅰ Very good Qinhuangdao Sep. 8‎ ‎52‎ PM10‎ Ⅱ Good Qingdao Sep. 8‎ ‎68‎ PM10‎ Ⅱ Good Shanghai Sep. 8‎ ‎67‎ PM10‎ Ⅱ Good Shenyang Sep. 8‎ ‎88‎ PM10‎ Ⅱ Good Tianjin Sep. 8‎ ‎54‎ PM10‎ Ⅱ Good Graph 2: Chinese National Standard API Values Levels of health concern Colors When the API is in this range:‎ ‎...air quality conditions are:‎ ‎...as symbolized by this color:‎ ‎0 to 50‎ Very good Blue ‎51 to 100‎ Good Green ‎101 to 150‎ Slight pollution Yellow ‎151 to 200‎ Moderate pollution Orange ‎201 to 250‎ Medium pollution Red ‎251 to 300‎ High pollution Purple ‎301 to 500‎ Hazardous Brown Notes:‎ ‎ **API stands for Air Pollution Index(指数).‎ ‎ **Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment.

If you are, you have got phobia (a very strong feeling of being afraid of something). Of all human fears, phobias may be the most uncontrollable. They are most often caused by a particular situation or object. In general, phobias can mainly be divided into three varieties. To begin with, agoraphobia is a fear of staying in strange surroundings, for example, an unfamiliar place, or an open area．Social phobia refers to the anxiety people show when they have to stay or perform on social events, for instance, speaking in front of the class. Lastly, there are a wide range of specific phobias. People suffering from this kind of phobia are terrified of specific objects or creatures. such as spiders, perhaps to your surprise, clowns. Besides, there are about six hundred and fifty phobias having been listed by psychologists(心理学家)as yet.‎ Faced with their phobias, many people choose to do nothing but just escape the situations or objects they fear. Psychologists, however, warn that if not treated properly, this kind of anxiety will get worse, so that it may disturb the sleep pattern, cause physical symptoms, and finally affect ‎ their daily activities. As for treatment, clinical research has discovered that medicine for anxiety is not successful in curing phobias. However. the anxiety disorders can be efficiently treated through cognitive behavioral therapy (认知行为疗法), through which patients are led to inspect the connections between their own fear und the situation or object, and then actively choose the acceptable treatments. Also, other treatments proved effective in reducing phobias are Meditation(quiet thought that can help people relax), listening to calming music, and so on. ‎ ‎13．Phobias are mainly caused by .‎ ‎ A．anxiety B．animal attacks ‎ ‎ C．terrible dreams and imagination D．a certain situation or thing ‎ ‎14．Which do psychologists NOT use for effective treatment of phobias? ‎ ‎ A．To take medicine for anxiety ‎ ‎ B．To listen to comforting light music ‎ ‎ C．To lose oneself in a peaceful environment ‎ ‎ D．To understand the very source of one's own anxiety ‎ ‎15．Which of the following statements about phobias is CORRECT? ‎ ‎ A．Actors call help people to cure their phobias. ‎ ‎ B．Phobias can be divided into six hundred and fifty types. ‎ ‎ C．Those suffering from phobias may not sleep well or work normally. ‎ ‎ D．Cognitive behavioral therapy demands little participation from patients. ‎ ‎16．What do those with agoraphobia feel terrified and anxious about? ‎ ‎ A．Staying on a square. ‎ ‎ B．Touching insects, like spiders.‎ ‎ C．Being harmed by virus. ‎ ‎ D．Giving a speech in presence of many people.‎ 答案 DACA Passage 5‎ A new study suggests that the more teenagers watch television, the more likely they are to develop depression（沮丧；抑郁）as young adults. ‎ The researchers used a national long-term survey of adolescent health to investigate （调查）the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000. ‎ As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV. ‎ Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one. ‎ The researchers say they did not find any such relationship with the use of other media such ‎ as movies, video games or radio, etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use. ‎ The study didn’t explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression. ‎ Last December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University‎ of ‎Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active to read, to attend religious services and to vote. ‎ ‎17. The best title for this passage should be . ‎ A. Teens, Television and Depression ‎ B. Men Develop Depression Easier than Women ‎ C. Media Use is Harmful to Adolescents ‎ D. Take Great care of Teenager’s depression ‎ ‎18. The result of the research seems to prove . ‎ A. teenagers are more likely to develop depression than adults ‎ B. other media uses do no harm to adolescents ‎ C. TV probably causes teenagers to grow up with depression ‎ D. those who watch no TV will not develop depression ‎ ‎19. We can learn from the survey that of all the media use . ‎ A. computer games are teenagers’ favorite ‎ B. most teenagers prefer to listen to the radio ‎ C. teenagers enjoy watching TV very much ‎ D. newspaper is not included in the survey ‎ ‎20. According to the passage, what kind of activity may help prevent depression? ‎ A. Playing computer games. B. Taking part in sports. ‎ C. Listening to the radio. D. Watching movies. ‎ ‎21. We can conclude that a teenager should . ‎ A. play more video games instead of watching TV ‎ B. be active in taking part in outdoor activities ‎ C. be more active in watching educational TV programmes ‎ D. attend religious services and care for politics ‎ 答案 ACCBB ‎ Passage 6‎ It is hard to go after the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and sightings with bare eyes are too unreliable to give real insight into its behavior. ‎ So biologists were delighted early this year when, with the help of the Navy, they were able to track a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater detecting（探测）devices across the oceans. ‎ Tracking whales is but one example of an exciting new world just opening to civilian（平民的）scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential（潜在的）enemies. ‎ Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption（爆发）for the first time and that they plan similar studies. ‎ Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. ‎ The speed of sound in water is roughly one mile a second－slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope（听诊器）does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low—frequency ones, can often travel thousands of miles. ‎ ‎22. The passage is chiefly about . ‎ A. an effort to protect an endangered sea species ‎ B. the civilian use of a military system ‎ C. the introduction of a U. S. Navy top-secret weapon ‎ D. a new way to look into the behavior of blue whales ‎ ‎23. The underwater listening system was originally designed . ‎ A. to detect and locate enemy boats ‎ B. to monitor deep—sea volcanic eruptions ‎ C. to study the movement of ocean currents ‎ D. to replace the global radio communications network ‎ ‎24. What is the closest meaning of the underlined word “to track” in the second paragraph? ‎ A. to study B. to fight against ‎ C. to follow D. to try to kill ‎ ‎25. It can be inferred from the passage that . ‎ A. new radio devices should be developed for tracking the endangered blue whales ‎ B. blue whales are no longer endangered with the use of the new listening system ‎ C.opinions differ as to whether civilian scientists should be allowed to use military technology ‎ D. military technology has great potential uses outsides. the military forces ‎ ‎26. Which of the following is true about the U. S. Navy underwater listening net work? ‎ A. It is now partly accessible to civilian scientists. ‎ B. It has been replaced by a more advanced system· ‎ C. It became useless to the military after the cold war. ‎ D. It is a must in protecting endangered species. ‎ 答案 BACDA Passage 7‎ Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.‎ Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.‎ For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙).They speed the heart rate, raise blood pressure, or sugar into the blood, etc．In general the person feels excited and ready to act.‎ Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.‎ Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”‎ Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. They said that laughter is much healthier than anger.‎ ‎27． “Damaging emotion” means that _________. ‎ ‎ A．the emotion is harmless B．the emotion is harmful ‎ ‎ C．the feeling is very strong D．the feeling is hard ‎28. What statement is right? ‎ A．Were you angry, you would be cancered (得癌症). ‎ B．Once you are angry, you must be cancered.‎ C．Angry as you are often, you can't be cancered, ‎ D．Anger may cause you a cancer. ‎ ‎29. Expressing anger violently _________ repressing it according to some scientists.‎ ‎ A．is just the same as B．is more harmful than ‎ ‎ C．is no better than D．is much better than ‎ ‎30．According to the author, you'd better _________. ‎ ‎ A．never be angry ‎ ‎ B．cool it down before you express it ‎ ‎ C．laugh and laugh when you get angry ‎ ‎ D．admit you are wrong when you are angry ‎31. The passage may be taken from _________.‎ ‎ A. the advertisement B. a travel book C. a magazine D. the diary 答案 BDCBC Passage 8‎ Beyond two or three days, the world’s best weather forecasts are doubtful, and beyond six or seven they are worthless. ‎ The Butterfly Effect is the reason. For small pieces of weather—to a global forecaster, small can mean thunderstorms and blizzards (暴风雪)—any prediction becomes worse rapidly. Errors and uncertainties increase, from dust devils and storms up to continent-size eddies (旋涡) that only satellites can see.‎ The modern weather models work with net-like points sixty miles apart, and even so, some starting data have to be guessed, since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart, rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature, pressure, humidity (湿度), and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02, then 12.03… the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations (波动) that the computer will not know about. By 12.01, those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale, and so on up to the size of the globe.‎ ‎32．A weather forecast ______ in the world.‎ A．is reliable within one or two days ‎ B．is doubtful beyond 24 hours C．becomes useless beyond two or three days ‎ D．is still worthwhile in seven days ‎33．Usually there is a weather sub-station ______.‎ A．in every city B．every 60 miles C．between two cities D．every one foot ‎34．Which of the following statements is true? ‎ A．People have not placed sensors one foot apart in the atmosphere.‎ B．Scientists have already put sensors one foot apart in the world.‎ C．Every sensor gives perfectly accurate data a weatherman wants.‎ D．Ground weather stations and satellites can see every place on earth.‎ ‎35．Our computer will not be able to know about fluctuations because ______.‎ A．the sensors are not good enough ‎ B．they are hidden by the spaces between the sensors C．they are too far away ‎ D．they move very fast ‎ 答案 32.A 33.B 34.A 35.B Passage 9‎ In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don’t stop at 100! By comparison, in America only 3 people in 100, 000 reach 100. But these Russian old people aren’t alone．The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too．‎ ‎ These people remain healthy in body and spirit despite the passage of time．While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren．Even the idea of aging is foreign to them．When asked “at what age does youth end?” most of these old people had no answer．Several replied, “Well, perhaps at age 80．”‎ ‎ What accounts for this ability to survive to such old age, and to survive so well? First of all, hard physical work is a way of life for all of these long-lived people．They begin their long days of physical labor as children and never seem to stop．For example, Mr. Rustam Mamedov is 142 years of age．His wife is 116 years old．They have been married for 90 years．Mr. Mamedov has no intention of retiring from his life as a farmer．“Why? What else would I do?” he asks．‎ ‎ All these people get healthful rewards from the environment in which they work．They all come from mountainous regions．They live and work at elevations of 1,660 to 1,000 meters above sea level．The air has less oxygen and is pollution-free．This reduced-oxygen environment makes the heart and blood vessel system stronger．‎ ‎ Another factor that may contribute to the good health of these people is their isolation．To a great extent．They are separated from the pressures and worries of industrial society．‎ ‎ Inherited factors also play some role．Most of the longest-lived people had parents and grandparents who also reached very old ages．Good family genes may, therefore, be one factor in living longer．‎ ‎ It is clear that isolation from urban pressures and pollution, clean mountain air, daily hard word, moderate diets, good genes, and a youthful approach to life all contribute to the health and long life of all these people．‎ ‎36．In the Causasus region of Russian, how many people can reach the age of ‎100 in 10,000?‎ ‎ A．5 B．‎3 ‎ C．50 D．10,000‎ ‎37．The example of Mr and Mrs Mamedov implies that ___________．‎ ‎ A．some Caucasians aged 100 to 140 become weak．‎ ‎ B．some Caucasians aged 100 to 140 are too old to work in the fields．‎ ‎ C．physical work contributes a lot to their long life．‎ ‎ D．some Caucasians aged 100 to 140 are still working in the fields besides their great- great ‎ -grandchildren．‎ ‎38．What is the main way of life for all of these long-lived people? ‎ ‎ A．Retiring from their lives as farmers B．Having been married for 90 years ‎ C．Hard physical work D．No intentions ‎39．At elevations of 1,220 to 1,000 meters above sea level, the air ______‎ ‎ A．has less oxygen B．is pollution ‎ C．is pollution-free D．both A and C ‎40．The following factors except _________ contribute to the health and long life of all these people．‎ ‎ A．clean mountain air B．daily hard work ‎ C．stress and pressure D．good genes 答案 ACCDC Passage 10‎ China is going green. In order to reduce air pollution and oil-shortages, automobile manufacturers have announced their plans to develop hybrid vehicles(混合燃料汽车) for the Chinese market. Toyota’s hybrid car Prius will be ready to drive in China this week. Let’s have a look at the new car.‎ Any vehicle is hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery(电池) and gasoline(汽油). Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising(巡航). A specially designed battery motor provides extra power for running up hills or when extra acceleration(加速) is needed.‎ Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car’s gasoline engine is dormant(休眠). The electric motor will provide power until the car reaches about ‎24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.‎ The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over ‎24 km/h, when you step on the gas pedal(油门), you are actually telling the computer how fast you want to go.‎ The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator(发电机) and produce electricity to recharge the batteries. As a consequence, the car’s batteries will last for around 200,000 miles.‎ ‎41．The author writes this passage mainly to .‎ A．teach people how to drive a hybrid car ‎ B．introduce a new kind of “green”car C．show how to save their gasoline when driving a car D．announce plans to develop hybrid vehicles for China ‎42．The first sentence probably refers to .‎ A．there will be more and more green land in China B．China is still young and lacking experience C．China’s new cars are combinations of different green models D．China has started producing environmentally friendly cars ‎43．Which of the following is NOT true?‎ A．The hybrid cars reduce air pollution and oil-shortages.‎ B．The car’s gasoline engine doesn’t work until it reaches about ‎24 km/h.‎ C．This kind of car is completely controlled by an onboard computer.‎ D．A specially designed battery motor provides extra power when needed.‎ ‎44．What is the most important feature of hybrid cars?‎ A．They are powered by both a rechargeable battery and gasoline.‎ B．They are much quieter than traditional cars.‎ C．They only use 99 percent of their power to run up hills.‎ D．They have smaller engines than traditional gasoline ones.‎ 答案 BDCA Passage 11‎ Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water — whether for drinking, agriculture, industry or the raising of fish will always have to be met . Given that premise (前提), there are two basic routes we can go: more equal access to water or better engineering solutions.‎ Looking at the engineering solution first, a lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal changes of the river — the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the near future, governments will have no excuse for their ignorance.‎ The engineers’ ability to control water flows has created new kinds of unpredictability too. Dams in Africa have meant fewer fish, less grazing and less floodplain (洪泛区) agriculture — none of which were expected. And their average economic life is assumed to be thirty years. Dams don’t exist forever, but what will replace them is not clear.‎ The challenge for the future is to find new means of controlling water. Although GM technology (转基因) will allow us to breed better dry-land crops, there is no market for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World? ‎ ‎45．What’s the main idea of this passage?‎ ‎ A．The engineering solutions to water resource and their limitation.‎ ‎ B．The challenge for the future. ‎ ‎ C．The basic means of controlling water.‎ ‎ D．The challenge for developing crops.‎ ‎45．Which of the following statements is NOT true for meeting our basic needs for water?‎ ‎ A．Water resource should be used more reasonably.‎ ‎ B．More dams should be built in river basins.‎ ‎ C．More wetlands should be protected from destruction.‎ ‎ D．More dry-land crops could be developed in Africa.‎ ‎46．The author suggests that governments will have no excuse for their careless ignorance in the future because .‎ ‎ A．the ecological destruction will be known to the public by researchers ‎ ‎ B．the ecological destruction will no longer be a problem in the future ‎ ‎ C．the future is an information age ‎ ‎ D．governments will face greater challenge in the future ‎ ‎47．The author mentions all the problems caused by dams EXCEPT .‎ ‎ A．fewer fish B．less grazing land ‎ ‎ C．less floodplain agriculture D．less farming land ‎48．The last sentence probably implies that .‎ ‎ A．no one will invest in developing locally appropriate crops in Africa ‎ ‎ B．researchers have no interest in developing dry-land crops ‎ ‎ C．research on locally appropriate crops in the Third World may be profitable ‎ ‎ D．There is less water resource in the Third World ‎ 答案 ABCDA Passage 12‎ Britain is facing a sharp rise in its rat population as growing numbers of people leave fast food scraps in the street , an environment group warned . Keep Britain Tidy said the rodents(啮齿动物) were stopping their traditional hunts underground and were roaming the streets ,tempted by discarded burgers ,pizzas and crisps. "The rat population is on the rise and soon it'll be as common to see a rodent on our street as it is to see a dog or a cat," said group Director ,Sue Nelson. The practice of dumping fast food litter and scraps on the street rather than in the trash-with young men the worst offenders-was behind the rise. According to the National Rodent Survey in 2005, Britain's rat population has grown by nearly one quarter since 2000 and is now estimated at 60 million , two million more than the human population. On average a rat can give birth every 24--28 days and just a single pair of rats can produce a colony of ‎2,000 a year. Around 200 people a year get Weil's Disease——an infection which can lead to liver or kidney(肝肾) failure and eventually death and which is arrived in rat's waste. To highlight the issue , Keep Britain Tidy launched a cinema ad entitled "How close do you want them to get?" The advertisement gave a shocking image of a young woman sleeping in a bed of rots, echoing the nightmare scene from ‎ James Herbert's classic horror tale The Rats, in which mutant rodents begin to prey on(捕食)humans.‎ ‎49. Where did the rodents use to search for food?‎ A. In the Street . B. Under the ground.‎ ‎ C. From the trash cans. D. In burger shops.‎ ‎50.

Of course , there's the risk of dehydration (脱水) . But athletes now know they can also get into trouble by drinking too much. Too much water intake can lower levels of sodium (钠) in the blood The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research.‎ ‎ Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight.‎ ‎ One technique for deciding how much water you need is to get the exact numbers. Runners have to weight themselves before and after a run to determine how much water they've lost. If their weight drops by more than 2 percent , they have not drunk enough water.‎ Hypothermia (体温过低) occurs when runners drink so much water that blood salt levels drop off . A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can’t get their rings off , and then they might feel sick. They may not remember where they are. In fact , most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration , the new research has shown that the body is a remarkable machine that actually tells you you need water when you feel thirsty.‎ ‎53.

Modern holistic medicine is an approach that treats the whole patient, not just the disease. It is a way to maintain good health rather than cure illness . The most important influences on today's holistic medicine are ancient Chinese medicine and Indian Ayurvedic medicine, both of which promoted whole body health.‎ ‎ Holistic medicine usually combines diet ,physical exercise and meditation, together with other alternative techniques such as massage(按摩)and acupuncture(针灸). Herbal treatment, a practice of treating illness by using plants, is influenced by the writings of Culpeper as well as Chinese and Ayurvedic medicine. Homeopathy(顺势疗法)is one of the forms of holistic medicine which is widely practiced in Europe and the USA. Homeopathy began in Germany in the early 1800s, when Samuel Hahnemann described how very tiny doses(剂量)of a drug had an effect On his patients. According to Hahnemann, the more the drug was diluted(稀释), the stronger its effects . The substance selected would produce similar effects to the disease itself if given in large doses. In the UK homeopathy is regarded as a non-traditional but just about acceptable treatment.‎ ‎ Meditation and contemplation have an important role in holistic medicine. They were brought to Europe by Indian teachers who combined Indian Ayurvedic medicine with Western beliefs. Transcendental meditation (超脱静坐)is one of the best known of these techniques. People repeat words inside their heads to reach a state of deep relaxation.‎ ‎ The holistic movement has made many doctors look at the whole patient, not just the disease. Life-style, emotional problems and diet are just some of the factors that can affect a person's health. Holistic medicine emphasizes good diet, exercise and fresh air, all of which contribute to health . Some clinics now offer holistic medicine along with traditional treatments, so that their patients can choose a combination of treatments that suits them. One problem with holistic ‎ medicine is that it is difficult for people to be sure a doctor is reliable. To solve this, many countries want alternative doctors to form professional bodies.‎ ‎56.

One is that they do it like honeybees and remember visual clues, but experiments showed ants can travel in the dark. Another theory is that because ants run at a steady pace, they could time how long it took them to get to and fro. Other studies have shown that once ants find a good source of food, they teach other ants how to find it.‎ The ant “pedometer” technique was first proposed in 1904, but it remained untested until now. Scientists trained desert ants to walk along a straight path from their nest entrance to a feeder 30 feet away. If the nest or feeder was moved, the ants would break from their straight path after reaching the expected spot and search for their goal.‎ Try that on stilts. They glued stilt-like extentions to the legs of some ants to lengthen stride. The researchers shortened other ants’ stride length by cutting off the ants’ feet and lower legs,‎ ‎ reducing their legs to stumps.‎ The ants on stilts took the right number of steps, but because of their increased stride length, marched past their goal. Stump-legged ants, meanwhile, fell short of the goal. After getting used to their new legs, the ants were able to adjust their pedometer.‎ ‎61. What is the passage mainly about? ‎ A. Ants’ marching depends on counting their steps ‎ B. Desert ants know how to look for food ‎ C. The secret for ants’ marching is known to all ‎ D. Ants know how far their food is ‎62. Apart from counting their steps, how can ants find their way?‎ A. By smelling B. By communicating ‎ C.By hearing D. By recognising wind ‎63.About the ant pedometer, we know that______.‎ ‎ A. the technique is a recent discovery ‎ B. ants always walk along a straight path ‎ C. ants often change their nest to keep the pedometer ‎ D. the pedometer needs changing depending on new situations ‎64. According to the passage, the “stump-legged ants”_______.‎ ‎ A. have longer legs than ones on stilts B. have longer legs than the common ones ‎ C. need more steps to reach their goal D. can arrive at their goal as usual 答案 ABDC ‎
