    B
    Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep a problem that couldn’t be solved the night before can often appear more manageable, although the evidence（证据）until now has been personal experience. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can improve insight（洞察力）and problem-solving.
    “If you have some newly-got memories in your brain, sleep acts on these memories and rebuild them, so that after sleep the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist（神经病学专家）at the university. To test the theory, they taught volunteers two simple rules to help them turn some numbers into a new order．There was also a third，hidden rule，which could help them increase their speed in solving the problem．The researchers divided the volunteers into two groups：half were allowed to sleep after the training while the rest were forced to stay awake．Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group．“Sleep helped，”Born said in a telephone interview．“The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep，so it can act on the problem．”But Born admitted that he and his team don’t know how rebuilding of memories occurs or what governs it．Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can help develop creative thinking．Although the role of sleep in human creativity will still be a mystery，the research gives people good reason to fully respect their periods of sleep，they added．
    60．The underlined phrase“sleep on it”in Paragraph 1 probably means_________．
    A．to delay deciding something until the next day
    B．to get as much sleep as possible
    C．to go on sleeping without being disturbed
    D．to sleep till after the time you usually get up in the morning
    61．Jan Born and his team carried out the experiment through________．
    A．comparison    B．interview        C．survey          D．imagination
    62．It can be inferred from the passage that___________．
    A．people should sleep so long as they have time
    B．sleep is the only way to solve hard problems
    C．people have various periods of sleep   D．people know how sleep rebuilds memories
    63．What would be the best title for the passage?
    A．How Sleep Works．               B．Sleep Helps Solve Problems．
    C．No Evidence，But Well Founded．   D．Born’s Discovery on Sleep．

    .Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn't matter where you live--in the middle of a modern city, or a faraway village--the chances are that you' 11 be disturbed by jet planes, transistor radios, oil - powered engines, etc. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they' re working.
    Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.
    One recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn't change too much(music, for example) may even help people to concentrate.
    56. According to this passage, the noise pollution __
    A. has become the worst in the countryside  B. has become better in big cities
    C. has spread from cities to villages      D. has been controlled in modern cities
    57. What does background music refer to?
    A. Music played while people are working.   
    B. Music played in the backyard.
    C. Noise that continues while you' re listening to other noises.
    D. Music used to help people to concentrate.
    58. Some people have their hearing harmed __
    A. while listening to pop music            B. in complete silence
    C. when speaking loudly                  D. while watching TV
    59. Which of the following isn't included among the things causing noise?
    A. trucks           B. motorcycles   C. electric engines   D. jet planes
    60. Scientists have discovered that what prevents people from concentrating on something is
    A. all kinds of noise                   B. great changes in the level of noise
    C. background noise                  D. popular music

    One reaction to all the concern about tropical deforestation（砍伐森林） is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
    The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
    Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks ,disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
    Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
    Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
    Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realize the severe effects of tropical deforestation, it will be 20 years too late.
    Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
    58．The underlined word "synthetics" probably means a kind of _________.
    A．natural rubber   B．tropical material   C．man-made material   D．tropical tree
    59．In the last paragraph the author tries to__________.
    A．tell people how to avoid the tropical deforestation
    B．show us how important it is to protect the tropical forests
    C．persuade people to buy something synthetic
    D．let people realize the effect of tropical deforestation
    60．The author's attitude towards the tropical deforestation is____________.
    A．puzzling        B．cold        C．supporting       D．opposed

    C
    Sometimes we cry because we are sad and sometimes because we are extremely happy．An irritant(刺激物)，such as onion(洋葱) smell or grains of sand in the eye，can also make cry．In this case tears perform an obvious role in getting rid of substances that might harm the surface of the eye．
    Dr．William Frey of the Dry Eye and Tear Research Center at St．Paul in Minnesota，USA，believes that tears from emotional causes may perform a similar role．He thinks that crying could get rid of emotional stress by washing away a chemical in the blood caused by strong emotions. To prove his theory, he hopes first to identify this chemical and then see if it is found in tears of sadness or happiness．  
    So far, Dr．Frey has failed to find out the difference between emotional tears and tears caused by an irritant in the eye．This may be because these substances themselves cause a degree of stress and emotion．What he has identified in all tears is a variety of biochemicals(生化物)which are one of the causes of stress．A more detailed study may help us understand why sufferers from stress-related disorders cry less often than healthy people．Dr．Frey is also very interested to see if there are any physiological(生理学的)explanations for why women，in general，cry five times more often than men，on average．
    64. The main purpose of Dr．Frey’s study of tears is to           
    A. show that there are two types of tears，caused by irritants and by emotions
    B. find out the cause of stress-related problems and emotional disorders
    C. explain why women cry more often than men
    D. prove that tears can remove a chemical in the blood caused by strong emotions
    65. Which of the following is true according to the passage?
    A. Tears fail to help get rid of emotional stress．
    B. Irritants in the eye result in tears without causing stress and emotion．   
    C. Healthy people cry more often than those with stress-related problems．
    D. The biochemical identified by Dr．Frey has nothing to do with stress．
    66. We can learn from the passage that __________．
    A. crying does us more harm than good
    B. inner feelings don’t affect our bodies
    C. sorrow may cause some chemicals in our blood
    D. emotional tears are different from tears caused by irritants in the eye
    67. Dr．Frey believes that tears from emotional causes may play a role in getting rid of ______．
    A. emotional stress by washing away a chemical in the blood
    B. onion smell or grains of sand
    C. sufferings from irritants
    D. substances that might not harm the surface of the eye

    Gorillas are born with an international sign language of gestures that they use to communicate，says a new study from the University of St Andrews in Scotland.
    From beating their chests to putting objects on their heads，shaking their arms，and even bouncing on all fours，the animals use more than 100 gestures to communicate with each other
    Professor Richard Byrne，a psychiatrist involved in the research，says it was hard to figure out the meanings of the gestures.
    “We don't really know what the animals are thinking. Often the gestures have more than one meaning，depending on the context，”says Byrne.
    The study showed that the gorillas did not learn the ges­tures from each other，as had been expected，but performed them instinctively (本能地).
    “Everyone had assumed different groups of gorillas would learn different gestures，”he says. “But that's not what we found. The more sites we went to ,the more we saw the same gestures being used. They seem to be naturally equipped with a pretty complex system of communication.”
    The study also found that gestures were performed with close attention to the potential audience，so that silent sig­nals，for example， were only given when other apes could see them. Other gestures，such as the "disco arm shake" were only ever seen directed towards humans.
    Byrne believes that the findings may explain how the human language developed.
    “There has always been speculation（猜测）that the origins of the human language might lie in gestures，”he says.
    “Many researchers have therefore studied the gestural communication of the great apes for clues to the evolution­ary origins of human gestures，”he adds.
    Several studies have shown that great apes are capable of imitating gestures. However，the scientists found that what appeared to be copies of human actions were actually gestures the apes were already able to make themselves. They're “reusing” gestures from their own repertoire，not learning new ones.
    64.According to the passage，Richard Byrne's research has found      .
    A. different groups of gorillas would learn different gestures
    B. gorillas know the sign language from birth
    C. how gorillas learn from each other
    D. gorillas develop a variety of languages when growing up
    65.Why can't the researchers really know the meanings of gorilla gestures?
    A. Because gorillas possess the ability of making many kinds of gestures.
    B. Because they haven't made deep research into the animal.
    C. Because a gorilla gesture may have different meanings.
    D. Because gorillas can't exactly express their thoughts.
    66.If a gorilla wants to make a silent gesture towards another gorilla，he      .
    A. needs to know how many other gorillas are watching him
    B. needs to make noise first in order to draw attention
    C. will first make sure his gesture can be seen
    D. will first consider whether he can carry out his gesture
    67.According to the passage，many scientists study the sign language of great apes in order to      .
    A. find the origins of the human language
    B. find ways for people to communicate with apes
    C. learn how animals communicate
    D. discover the meanings of animal gestures
