Part Ⅱ 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 tricky10 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 stress—it 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 memorable11 message. Women’s magazines ran headlines like “Stress causes illness?” If you want to stay physically12 and mentally healthy? the articles said? avoid stressful events.   But such simplistic advice is impossible to follow. Even if stressful events are dangerous? many—like the death of a loved one—are impossible to avoid. Moreover? any warning to avoid all stressful events is a prescription13 (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 we’re 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 vigor14 than they had before. We also know that a long time without change or challenge can lead to boredom15? 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 1970’s led to ____ .   
A? widespread concern over its harmful effects   
B? great panic over the mental disorder16 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 1?Para.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-mindedness—forgetting where you left something or wondering why you just entered a room-are caused by a simple lack of attention? says Schacter. “You’re supposed to remember something? but you haven’t 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 don’t pay attention to what you did because you’re involved in a conversation? you’ll probably forget that the phone is in the jacket now hanging in your wardrobe (衣柜). “Your memory itself isn’t failing you?” says Schacter. “Rather? you didn’t 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 table—don’t 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 you’re 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 you’ll 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 considerably17   
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 reminder18 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 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 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 Navy’s formerly19 top-secret system of underwater listening devices spanning the oceans.   Tracking whales is but one example of an exciting new world just opening to civilian20 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 volcanic21 eruption22 (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 relatively23 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 marine24 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 vessels25   
B? to monitor deep-sea volcanic eruptions26   
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 capability27 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 aerobic28 exercise (有氧操). Millions of individuals became engaged in a variety of aerobic activities? and literally29 thousands of health spas developed around the country to capitalize (获利) on this emerging interest in fitness? particularly aerobic dancing for females. A number of fitness spas existed prior to this aerobic fitness movement? even a national chain with spas in most major cities. However? their focus was not on aerobics30? but rather on weight-training programs designed to develop muscular mass? strength? and endurance in their primarily male enthusiasts31. These fitness spas did not seem to benefit financially from the aerobic fitness movement to better health? since medical opinion suggested that weight-training programs offered few? if any? health benefits. In recent years? however? weight training has again become increasingly popular for males and for females. Many current programs focus not only on developing muscular strength and endurance but on aerobic fitness as well.
  Historically? most physical-fitness tests have usually included measures of muscular strength and endurance? not for health-related reasons? but primarily because such fitness components32 have been related to performance in athletics34. However? in recent years? evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well. The American College of Sports Medicine now recommends that weight training be part of a total fitness program for healthy Americans. Increased participation35 in such training is one of the specific physical activity and fitness objectives of Healthy People 2000? National Health Promotion36 and Disease Prevention Objectives.   

36. The word “spas”Line 3?Para.1? most probably refers to ____.   
A? sports activities
C? recreation centers   
B? places for physical exercise
D? athletic33 training programs.

试卷二  
Part Ⅳ Short Answer Questions 15 minutes?  
Directions? In this part there is a short passage with five questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words not exceeding 10 words?.

  As researchers learn more about how children’s intelligence develops? they are increasingly surprised by the power of parents. The power of the school has been replaced by the home. To begin with? all the factors which are part of intelligence—the child’s understanding of language learning patterns curiosity—are established well before the child enters school at the age of six. Study after study has shown that even after school begins? children’s achievements have been far more influenced by parents than by teachers. This is particularly true about learning that is language-related. The school rather than the home is given credit for variations in achievement in subjects such as science.

  In view of their power it’s sad to see so many parents not making the most of their child’s intelligence. Until recently parents had been warned by educators who asked them not to educate their children. Many teachers now realize that children cannot be educated only at school and parents are being asked to contribute both before and after the child enters school.

  Parents have been particularly afraid to teach reading at home. Of course children shouldn’t be pushed to read by their parents but educators have discovered that reading is best taught individually—and the easiest place to do this is at home. Many four and five-year-old who have been shown a few letters and taught their sounds will compose single words of their own with them even before they have been taught to read.   

Questions? (注意:答题尽量简短,超过10个词要扣分。每条横线限写一个英语单词,标点符号不占格。)   
S1. What have researchers found out about the influence of parents and the school on children’s intelligence﹖
S2. What do researchers conclude about children’s learning patterns﹖
S3. In which area may school play a more important role﹖
S4. Why did many parents fail to make the most of their children’s intelligence﹖
S5. The author suggests in the last paragraph that parents should be encouraged to

Passage Two   
Did you know that there’s a kind of bird that can sew﹖ This called the tailor bird uses its mouth as a needle. It sews leaves together in the shape of a cup? then it adds a layer of straw to the inside of the cup and lays its eggs there. Each bird species builds its own special kind of nest. The most common materials used for nests are grasses? branches and feathers. A bird must weave these materials into a nest. Just imagine building a house without cement or nails to hold together?  
Another bird is called the weaver53 bird. The weaver bird builds a nest that looks like a basket? the nest shaped like a pear with a hole in the middle. The hole is the door of the nest. A third bird is called the oven bird. The oven bird makes a nest that is very solid. The nest is made of mud. The oven bird forms the mud into the shape of an oven and then let it dry in the sun. The sun bakes the mud making it very hard. Not all birds make their homes in branches. Some birds build their nests on the ground? while others bury their eggs under the ground. And some birds do not build nests at all. So when you look for nests and eggs in branches of the trees and bushes? remember that some nests may be right your feet.   

14. What does the nest built by tailor bird look like ﹖  
15. Why is there a hole in the weaver bird’s nest ﹖  
16. What is the oven bird’s nest made of ﹖  
17. What might surprise us about birds’ nests according to the speaker ﹖  

Passage Three   
  You can tell the age of a tree by counting its rings? but these records of trees’ life really say a lot more. Scientists are using tree rings to learn what’s being happening on the sun’s surface for the last ten thousand years. Each ring represents a year of growth. As the tree grows? it adds a layer to its trunk taking up chemical elements from the air. By looking up the elements in the rings for a given year? scientists can tell what elements were in the air that year. Doctors Stevenson is analysing one element——carbon-14 in ring from both living and dead trees. Some of the rings go back almost ten thousand years to the end of the Ice Age. When Stevenson followed the carbon-14 trail back in time? he found carbon-4 levels change with the intensity of solar burning. You see? the sun has cycles. Sometimes it burns fiercely and other times it’s relatively calm. During the sun’s violent periods? it throws off charged particles in fast moving strings54 called solar winds. The particles interfere55 with the formation of carbon-14 on earth. When there’s more solar wind activity? less carbon-14 is produced. Ten thousand years of tree rings show that the carbon-14 level rises and falls about every 420 years. The scientists concluded that the solar wind activity must follow the same cycle.

18. What is the purpose of the scientists in studying tree rings ﹖  
19. What affects the amount of carbon-14 on earth ﹖  
20. What do we learn from the passage about the solar wind activity ﹖
