    Have you wondered why different animals or pests have their particular colors? Colors in them seem to be used mainly to protect themselves.
    Birds, especially seagulls are very fond of locusts, but birds can’t easily catch locusts because locusts change their colors together with the change of the color of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown color as crops have. Some other pests with different colors from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night.
    If you study the animal life in any part of the world, you will find the main use of coloring is to protect themselves, bears, wolves and other beasts move quietly through forests. They are usually invisible to the eyes of hunters, because they have the color much like the barks(树皮) of trees.
    An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid is over, its enemies cannot find it, and it quickly swims away. Thus, it has existed up to now though it is not powerful at all.
    小题1:This passage mainly talks about ______.
    A．the change of color in locusts
    B．the protective coloration of animals and pests
    C．how a certain sea fish protects itself
    D．animals or pests can dye themselves different colors
    小题2:Locusts are ______ but they aren’t easily wiped out(消灭)by their enemies because _______.
    A．animals; they are powerful enough
    B．beasts; they are dangerous to their enemies
    C．pests; they take on the same colors as crops
    D．birds; they fly very fast
    小题3:What does the underlined word “invisible” in Paragraph 3 mean?
    A．can’t be seenB．can be seenC．can’t moveD．can’t change

    小题1:B
    小题2:C
    小题3:A
    文章主要谈论的是动物使用颜色来保护自己的问题。
    小题1:B 主旨大意题。文章主要谈论的是动物使用颜色来保护自己的问题。
    小题2:C 细节题。根据Birds, especially seagulls are very fond of locusts, but birds can’t easily catch locusts because locusts change their colors together with the change of the color of crops.可知C正确。
    小题3:A 猜测词义题。根据because they have the color much like the barks(树皮) of trees.

    Scientists in Canada say big ocean fish have almost disappeared from the world since the start of industrial fishing in the nineteen-fifties. The scientists found that population of large fish like tuna; swordfish and cod have dropped by ninety percent in the past fifty years.
    The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.
    The scientists say the common method called longline fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be close to one-hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.
    Longline fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one-hundred hooks. The study says longline fishing boats now might catch one fish per hundred hooks.
    The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years.
    Ransom Myers of Dalhousie University in Nova Scotia led the study with Boris Worm of Dalhousie and the University of Kiel in Germany. Mister Worm says the destruction could lead to a complete re-organization of ocean life systems. Mister Meyers says the decreased number of large fish is not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors(祖先). He says not only are there fewer big fish, they are smaller than those of the past.
    American government scientists say even with the best efforts to protect fish populations, decreases are to be expected.
    小题1:Where is the passage probably taken from?
    A．A story book.
    B．A business magazine.
    C．An environment report.
    D．An economic survey.
    小题2:Big fish have gradually been disappearing especially because ________.
    A．longline fishing method is used
    B．sea water is getting polluted
    C．mankind destroys the environment
    D．governments don’t make the best efforts
    小题3:Which of the following shows the fact that the populations of large fish have dropped?
    A．Today’s “large”fish are smaller than those of the past.
    B．Longline boats now might catch fewer fish every one-hundred hooks.
    C．Fish even able to reproduce don’t have the chance to live longer.
    D．Japanese boats could catch about ten fish for every 100 hooks.
    小题4:What can be the best title?
    A．Discoveries Canadian Scientists Have Made
    B．Japanese Fishing Industry
    C．Losses of Big Fish
    D．Modern Fishing Methods
    小题5:When did the researchers begin to survey the decreasing of large fish?
    A．In the 1960s.B．In the 1970s.C．In the 1980s.D．In the 1990s.

    If we were asked exactly what we were doing a year ago，we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day，we should be able to give an answer to the question.
    It is the same in history .Many things have been forgotten because we do not have any written account of them .Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war．Sometimes there was never any written record at all because the people of that time and place did not know how to write．For example，we know a good deal about the people who lived in China 4，000 years ago, because they could write and leave written records for those who lived after them．But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write．
    Sometimes, of course，even if the people cannot write，they may know something of the past．They have heard about it from older people，and often songs and dances and stories have been made about the most important happenings，and these have been sung and acted  and told for many generations, for most people are proud to tell what their fathers did in the past．This we may call  “remembered history”．Some of it has now been written down. It is not so exact or so valuable to us as written history is，because words are much more easily changed when used again and again in speech than when copied in writing．But where there are no written records，such spoken stories are often very helpful．
    小题1:Which of the following ideas is not suggested in the passage?
    A．“Remembered history”，compared with written history，is less reliable
    B．Written records of the past play the most important role in our learning of the human history．
    C．A written account of our daily activities helps US to be able to answer many questions．
    D．Where there are no written records．there is no history．
    小题2:We know very little about the central Africa 200 years ago because ___
    A．there was nothing worth being written down at that time
    B．the people there ignored the importance of keeping a record
    C．the written records were perhaps destroyed by a fire
    D．the people there did not know how to write
    小题3:“Remembered history” refers to ___．
    A．history based on a person’s imagination
    B．stories of important happenings passed down from mouth to mouth
    C．songs and dances about the most important events
    D．both B and C
    小题4:“Remembered history”is regarded as valuable only when ____.
    A．it is written downB．no written account is available
    C．it proves to be timeD．people are interested in it
    小题5:The passage suggests that we could have learned much more about our past than we do now if the ancient people had _____
    A．kept a written record of every past event
    B．not burnt their written records in wars
    C．told exact stories of the most important happenings
    D．made more songs and dances

    Water, which covers about 74 percent of the earth’s surface, is man’s most precious resource. Without it we cannot live. Clean water keeps us alive; polluted water means disease and death.Keeping our water pure is by no means an easy task but it is something that must be done.
    Hong Kong once prided herself on being the “Fragrant Harbour”. However, these days, it is not certain if Hong Kong’s harbour could still be called “fragrant”. For, like many other places, Hong Kong has not been spared water pollution. A visit to Tolo and Victoria Harbour, or any of the beaches in Hong Kong is enough to make one aware of the ugly truth that Hong Kong waters are indeed polluted.
    The great threat to our water is bacteria pollution. Another great source of water pollution is poisonous chemicals. These substances, which are found in industrial waste and agricultural pesticides, make up unseen dangers that enter biological food chains.
    Pollution control is a continuing problem for the government. It is believed that the most effective form of control is legislation（立法）. Most importantly, the present laws on pollution should be given more force. On the other hand, no amount of legislation can effectively control pollution unless those concerned are properly educated about the danger posed by pollution.
    While a great majority of Hong Kong citizens and residents seem to be greatly concerned about ways to control water pollution, it is discouraging to note that there are, in our midst, some people who remain apathetic（无动于衷）about the problem. In a recent radio programme conducted on what people in the streets thought about the water pollution problem, one apparently unconcerned person said, “What do I care about water pollution? I don’t drink polluted water. As long as the water I drink is not polluted, I’m not bothered. Water pollution is too big a problem and let’s leave it to the government.”
    If all residents in Hong Kong will take such an indifferent attitude, all the government’s attempts to control pollution, let alone the anti-pollution legislation, will prove useless. The best form of pollution control each citizen can employ is to be aware of his surroundings. We hope that someday, the problem of water pollution in Hong Kong will cease to alarm us.
    小题1:By the underlined sentences, the writer wants to show that ______.
    A．we should not use polluted water
    B．it is our responsibility to keep our water clean and safe
    C．clean water is vitally important to the survival of human beings
    D．water is abundant but very expensive
    小题2:What can you infer from the second paragraph?
    A．Hong Kong indeed deserves the name.
    B．Hong Kong never deserves such a name.
    C．Hong Kong can’t avoid the damage of pollution.
    D．Hong Kong has failed to live up to such reputation.
    小题3:The writer quotes the words in the programme to show us that a block to the solution of the problem is _________.
    A．people’s lack of education
    B．people’s I-don’t-care attitude
    C．people’s wait-and-see attitude
    D．people’s over-dependence on the government
    小题4:In the final analysis, the best approach to the problem of water pollution is ________.
    A．legislation
    B．rapid development of modern science
    C．mass education
    D．everybody taking care of his own surroundings

    We had known for along time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at special time. The question is not as simple as we might think, as recent experiments have shown. In one experiment, flowers were kept in constant (持续的）darkness. We might expect that the flowers ,without any information about the time of the day, did not open as they usually do. In fact, they continue to open at their usual time. This shows that they have some special ways of knowing the time. Their sense(感觉) time does not depend on information from the outside world. It is inside them: a kind of "inner (内部的）clock". This discovery may not seem to be very important. However, it is later found that not just plants but animals have this "inner clock" which control（控制）the working of their bodies and influences their activities. Human beings, then, are also influenced by it. Whether we wish or not, itaffectssuch things in our life as our need for sleep or need for food.

    Does this sound familiar? It’s 3:00 am and you’re still awake and staring at the clock. You can’t sleep , and you’ve already tried all the familiar tricks – taken a warm bath , drunk a glass of heated milk ,tried counting sheep, and read a book –all with no success. If you are such a sufferer, remember you’re not alone. Experts said that one in every four Americans have trouble falling or staying asleep.
    Lack of sleep can hurt your quality of life in so many ways. Short temper, impatience, poor decision-making, and mood swings are common among those with sleeping problems.

However, it makes sense to weigh the available treatments before choosing the one that’s right for you. Other sleep aids may seem like a quick fix, but it turns out that there are many disadvantages of these drugs. For one thing, they may require expensive, time-consuming trips to your physician. They may also be habit-forming or have unpleasant side effects like dizziness( 眩晕) dry mouth, and next-day sleepiness. Plus , they become less effective over time.
