A supermarket club card is a new way for people to save money on items they buy. People used to cut out coupons (赠券)to(S1) save money. Now they use a card that looks like a(S2)credit card when they pay for items. Only people with cards can get the(S3)lower price.
　　To get a card, people must give out their name, address, and other(S4)personal information. Everything club card-users buy is (S5)stored on a computer in a file with their name on it.

Stores that use club cards have promised to keep the information private. (S10)Some people are afraid the stores might change their minds if companies offered enough money. Some people say the information is worth as much as treasure.

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 11 to 15 are based on the following passage.
　　The predictability of our mortality rates is something that has long puzzled social scientists. After all, there is no natural reason why 2,500 people should accidentally shoot themselves each year or why 7,000 should drown or 55,000 die in their cars. No one establishes a quota for each type of death. It just happens that they follow a consistent pattern year after year.
　　A few years ago a Canadian psychologist named Gerald Wilde became interested in this phenomenon. He noticed that mortality rates for violent and accidental deaths throughout the Western world have remained oddly static throughout the whole of the century, despite all the technological advances and increases in safety standards that have happened in that time. Wilde developed an intriguing theory called “risk homeostasis”. According to this theory, people instinctively live with a certain level of risk. When something is made safer, people will get around the measure in some way to reassert the original level of danger. If, for instance, they are required to wear seat belts, they will feel safer and thus will drive a little faster and a little more recklessly, thereby statistically canceling out the benefits that the seat belt confers. Other studies have shown that where an intersection is made safer, the accident rate invariably falls there but rises to a compensating level elsewhere along the same stretch of road. It appears, then, that we have an innate need for danger.
　　In all events, it is becoming clearer and clearer to scientists that the factors influencing our lifespan are far more subtle and complex than had been previously thought. It now appears that if you wish to live a long life, it isn’t simply a matter of adhering to certain precautions … eating the right foods, not smoking, driving with care. You must also have the right attitude. Scientists at the Duke University Medical Center made a 15-year study of 500 persons personalities and found, somewhat to their surprise, that people with a suspicious or mistrustful nature die prematurely far more often than people with a sunny disposition. Looking on the bright side, it seems, can add years to your life span.

　　A) wearing seat belts does not have any benefits from the statistic point of view
　　B) deaths from wearing seat belts are the same as those from not wearing them
　　C) deaths from other reasons counterbalance the benefits of wearing seat belts

　　Passage Two
　　Questions 16 to 20 are based on the following passage.
　　In California the regulators, the utilities and the governor all want the Federal Energy Regulatory Commission to cap spot (现货的) market prices. The Californians claim it will rein in outrageous prices. Federal regulators have refused. The battle is on.
　　Governor Gray Davis says,“I’m not happy with the Federal Regulatory Commission at all. They’re living in an ivory tower. If their bills were going up like the people in San Diego, they would know that this is a real problem in the real world.”
　　As part of deregulation, price caps were removed to allow for a free market. Timing is everything; natural gas prices had already skyrocketed. Demand was high from California’s booming economy. No new power plants had been built here in ten years, and power producers had the right to hike prices along with demand. And hike them they did.
　　Loretta Lynch of the Public Utilities Commission says,” This commission and all of California was beating down the door of federal regulators to say‘help us impose reasonable price caps to help to keep our market stable.”
　　Federal regulators did ask for longer-term contracts between power producers and the utilities to stabilize prices. The federal commission, unavailable for comment on this story, released a recent statement defending its position not to re-regulate.
　　Federal Energy Regulatory Commission Dec. 15, : “The commissions intention is to enable the markets to catch up to current supply and demand problems and not to reintroduce command and control regulation that has helped to produce the current crisis.”
　　Some energy experts believe that, without temporary price caps, the crisis will continue.
　　Severin Borenstein of the U.C. Energy Institute says,“Some federal regulators have a blind commitment to making the market work and I think part of the problem is they really dont understand whats going on.”
　　Gary Ackerman of the Western Power Trading Forum says,“He’s dead wrong about that. The federal regulators understand far better than any individual state that, though it might be painful and it certainly is painful in California, price caps don’t work. They never work.”
　　16. The battle between Californians and federal regulators is about .
　　A) control over the price of power
　　B) necessity of removing price caps
　　C) hiking the energy prices in California
　　D) a regulation concerning power supply
　　17. Governor Gray Davis was dissatisfied with the Federal Regulatory Commission because .
　　A) they did not know what the real problem was
　　B) they were living an easy life in an ivory tower
　　C) they could not experience the life in San Diego
　　D) they turned a blind eye to the situation in California
　　18. The Federal Commission uncapped the energy price with the intention to .
　　A) help California’s economy booming steadily
　　B) prevent power price from going up any further
　　C) enable the market to deal with supply and demand problems
　　D) have contracts signed between power producers and the utilities

　　B) the current crisis is partly attributed to previous command and control policy
　　C) price caps can temporarily solve energy problems an individual state meets with
D) they do understand what is going on in California and will take proper measures

　　Passage Three
　　Questions 21 to 25 are based on the following passage.
　　Another cultural aspect of nonverbal communication is one that you might not think about: space. Every person perceives himself to have a sort of invisible shield surrounding his physical body. When someone comes too close, he feels uncomfortable. When he bumps onto someone, he feels obligated to apologize. But the size of a person’s “comfort zone” depends on his cultural ethnic origin. For example, in casual conversation, many Americans stand about four feet apart. In other words, they like to keep each other “at arms length”,people in Latin or Arab cultures, in contrast, stand very close to each other, and touch each other often. If someone from one of those cultures stands too close to an American while in conversation, the American may feel uncomfortable and back away.
　　When Americans are talking, they expect others to respond to what they are saying. To Americans, polite conversationalists empathize by displaying expressions of excitement or disgust, shock or sadness. People with a “poker face”, whose emotions are hidden by a deadpan expression, are looked upon with suspicion. Americans also indicate their attentiveness in a conversation by raising their eyebrows, nodding, smiling politely and maintaining good eye contact. Whereas some cultures view direct eye contact as impolite or threatening, Americans see it as a sign of genuineness and honesty. If a person doesn’t look you in the eye, American might say, you should question his motives—or assume that he doesn’t like you. Yet with all the concern for eye contact, Americans still consider staring—especially at strangers—to be rude.
　　21. What the author discussed in the previous section is most probably about .
　　A) classification of nonverbal communication
　　B) the reasons why people should think about space
　　C) the relationship between communication and space
　　D) some other cultural aspects of nonverbal communication
　　22. How far people keep to each other while talking is closely associated with their .
　　A) origin B) culture C) custom D) nationality
　　23. When an Italian talks to an Arabian on informal occasions,.
　　A) he stands about four feet away
　　B) “comfort zone” does not exist
　　C) keeping close enough is preferred
　　D) communication barriers may emerge
　　24. A “poker face” (Line 3,Para. 2) refers to a face which is .
　　A) attentive B) emotional C) suspicious D) expressionless
　　25. In a conversation between friends, Americans regard it as sincere and truthful to .
　　A) maintain direct eye contact
　　B) hide emotions with a deadpan expression
　　C) display excitement or disgust, shock or sadness
D) raise their eyebrows,nod and smile politely

　　Passage Four
　　Questions 26 to 30 are based on the following passage.
　　We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provi
