Part Reading Comprehension 35 minutes Directions: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. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Passage One: Questions 21 to 25 are based on the following passage In the 1960s medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like “serious illness of a family member” were high on the list but so were some positive life-changing events like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stressit only shows how much you have to deal with. And we now know that the way you handle these events dramatically affects your chances of staying healthy. By the early 1970s hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Womens magazines ran headlines like “Stress causes illness” If you want to stay physically and mentally healthy the articles said avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous manylike the death of a loved oneare impossible to avoid. Moreover any warning to avoid all stressful events is a prescription (处方) for staying away from opportunities as well as trouble. Since any change can be stressful a person who wanted to be completely free of stress would never marry have a child take a new job or move. The notion that all stress makes you sick also ignores a lot of what we know about people. It assumes were all vulnerable (脆弱的) and passive in the face of adversity (逆境). But what about human initiative and creativity Many come through periods of stress with more physical and mental vigor than they had before. We also know that a long time without change or challenge can lead to boredom and physical and mental strain. 21. The result of Holmes-Rahe's medical research tells us _ . A the way you handle major events may cause stress B what should be done to avoid stress C what kind of event would cause stress D how to cope with sudden changes in life 22. The studies on stress in the early 1970s led to _ . A widespread concern over its harmful effects B great panic over the mental disorder it could cause C an intensive research into stress-related illnesses D popular avoidance of stressful jobs 23. The score of the Holmes-Rahe test shows _ . A how much pressure you are under B how positive events can change you life C how stressful a major event can be D how you can deal with life-changing events 24. Why is “such simplistic advice”Line 1Para.3 impossible to follow A No one can stay on the same job for long B No prescription is effective in relieving stress C People have to get married someday D You could be missing opportunities as well 25. According to the passage people who have experienced ups and downs may become _ . A nervous when faced with difficulties B physically and mentally strained C more capable of coping with adversity D indifferent toward what happens to them Passage Two: Questions 26 to 30 are based on the following passage Most episodes of absent-mindednessforgetting where you left something or wondering why you just entered a room-are caused by a simple lack of attention says Schacter. “Youre supposed to remember something but you havent encoded it deeply.” Encoding Schacter explains is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket for example and dont pay attention to what you did because youre involved in a conversation youll probably forget that the phone is in the jacket now hanging in your wardrobe (衣柜). “Your memory itself isnt failing you” says Schacter. “Rather you didnt give your memory system the information it needed.” Lack of interest can also lead to absent-mindedness. “A man who can recite sports statistics from 30 years ago” says Zelinski “may not remember to drop a letter in the mailbox.” Women have slightly better memories than men possibly because they pay more attention to their environment and memory relies on just that. Visual cues can help prevent absent-mindedness says Schacter. “But be sure the cue is clear and available” he cautions. If you want to remember to take a medication (药物) with lunch put the pill bottle on the kitchen tabledont leave it in the medicine chest and write yourself a note that you keep in a pocket. Another common episode of absent-mindedness walking into a room and wondering why youre there. Most likely you were thinking about something else. “Everyone does this from time to time” says Zelinski. The best thing to do is to return to where you were before entering the room and youll likely remember. 26. Why does the author think that encoding properly is very important A It helps us understand our memory system better B It enables us to recall something from our memory C It expands our memory capacity considerably D It slows down the process of losing our memory 27. One possible reason why women have better memories than men is that _ . A they have a wider range of interests B they are more reliant on the environment C they have an unusual power of focusing their attention D they are more interested in what's happening around them 28. A note in the pocket can hardly serve as a reminder because _ . A it will easily get lost B it's not clear enough for you to read C it's out of your sight D it might get mixed up with other things 29. What do we learn from the last paragraph A If we focus our attention on one thing we might forget another. B Memory depends to a certain extent on the environment. C Repetition helps improve our memory. D If we keep forgetting things we'd better return to where we were. 30. What is the passage mainly about A The process of gradual memory loss. B The causes of absent-mindedness. C The impact of the environment on memory. D A way of encoding and recalling.Passage Three: Questions 31 to 35 are based on the following passage It is hard to track the blue whale the oceans 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 visual sightings 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 Navys formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of an exciting new world just opening to civilian 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 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 patients chest to a doctors 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. 31. The passage is chiefly about _ . A an effort to protect an endangered marine species. B the civilian use of a military detection system. C the exposure of a U.S. Navy top-secret weapon. D a new way to look into the behavior of blue whales. 32. The underwater listening system was originally designed _ . A to trace and locate enemy vessels B to monitor deep-sea volcanic eruptions C to study the movement of ocean currents D to replace the global radio communications network 33. The deep-sea listening system makes use of _ . A the sophisticated technology of focusing sounds under water B the capability of sound to travel at high speed C the unique property of layers of ocean water in transmitting sound D low-frequency sounds travelling across different layers of water 34. 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 in civilian use 35. Which of the following is true about the U.S. Navy underwater listening network 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 indispensable in protecting endangered species. Passage Four: Questions 36 to 40 are based on the following passage The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise (有氧操
