Few doctors believe any longer that it is simply a question of will power. And for those people that continue to view addicts as merely "weak", recent genetic research may force a rethink. A study conducted by Jacqueline Vink, of the Free University of Amsterdam, used a database called the Netherlands Twin Register to analyze the smoking habits of twins. Her results, published in the Pharmacogenomics Journal, suggest that an individual's degree of nicotine dependence, and even the number of cigarettes he smokes per day, are strongly genetically influenced. The Netherlands Twin Register is a voluntary database that contains details of some 7,000 pairs of adult twins (aged between 15 and 70) and 28,000 pairs of childhood twins. Such databases are prized by geneticists because they allow the comparison of identical twins (who share all their genes) with fraternal twins (who share half). In this case, however, Dr. Vink did not make use of that fact. For her, the database was merely a convenient repository of information. Instead of comparing identical and fraternal twins, she concentrated on the adult fraternal twins, most of whom had completed questionnaires about their habits, including smoking, and 536 of whom had given DNA samples to the register. The human genome is huge. It consists of billions of DNA "letters", some of which can be strung together to make sense (the genes) but many of which have either no function, or an unknown function, To follow what is going on, geneticists rely on markers they have identified within the genome. These are places where the genetic letters may vary between individuals. If a particular variant is routinely associated with a particular physical feature or a behavior. pattern, it suggests that a particular version of a nearby gene is influencing that feature or behavior. Dr. Vink found four markers which seemed to be associated with smoking. They were on chromosomes 3, 6, 10 and 14, suggesting that at least four genes are involved. Dr. Vink hopes that finding genes responsible for nicotine dependence will make it possible to identify the causes of such dependence. That will help to classify smokers better (some are social smokers while others are physically addicted) and thus enable "quitting" programs to be customized. Results such as Dr. Vink's must be interpreted with care. Association studies, as such projects are known, have a disturbing habit of disappearing, as it were, in a puff of smoke when someone tries to replicate them. But if Dr. Vink really has exposed a genetic link with addiction, then Mark Twain's problem may eventually become a thing of the past. Mark Twain is mentioned in the passage in order to show that A．he is a man with very Strong will power. B．it is easy to give up smoking temporarily. C．famous writers are often heavy smokers. D．only few people have his determination.

A．people will become isolated B．interpersonal relation will disappear C．people will be controlled by network D．there will be too many social activities

A perversely B adversely C inversely D diversely

A．Because it is considered by psychologists to be an undesirable trait. B．Because it is not a trait associated with social animals. C．Because our ancestors were not shy, so we should be like them. D．Because shy people could not have survived in early human society.

I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a grocery store in the neighborhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and I began to remember vaguely the incident he was de scribing. I was about eight years old at the time, and I had gone into the store with my mother to do the weekly grocery shopping. On that particular clay, I must have found my way to the dairy food department where the incident tool place. (80) There must have been a special sale on eggs that day be cause there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together; so I went to work. The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees inspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was culprit(罪犯). He severely scolded me and wanted me to pay for any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not. How old was the author when he wrote this article？ A．About 8. B．About 18. C．About 23. D．About 15.

But, there's another side. SARS is a reminder of how fragile (脆弱的)life can be. Suddenly, it's not just the old people who are thinking about death. Everyone now realizes there might not always be a tomorrow. Li Ping, a Senior 3 student in Taiyuan, Shanxi Province, came into contact(接触)with a suspected(疑似)SARS patient in mid-April. He was told to stay at home for at least two weeks. "Watching TV about more and more SARS patients dying, ! never knew that death could be so close. Life is Valuable and I am going to treasure every single day." he said. SARS teaches people to be grateful, not only for their own lives, but also for others. Doctors and nurses, for example, have to spend all their time with infected(被感染的)patients. As a result, more than 20 percent of SARS cases in China are medical workers. Liu Yu, a Senior 2 student of Beijing No. 5 Middle School, wants to be a doctor when he grows up. "Although they certainly know of the dangers, doctors and nurses remain bravely dedicated(致力于)to saving people's lives. I was deeply moved by what they have done. I think they are real heroes." he said. SARS also teaches sympathy(同情). The past few weeks have been terrible for Chinese people. But there are far worse things than SARS in this world, such as war, earthquakes and murders. Think of the Iraqis, who have been living terrible lives for 20 years. Think of how the Americans felt on 9. 11. And finally, SARS offers the chance to grow. All different types of people and government officials are joining together to cope with this difficult time. When this passes, China and its people, will have learned great lessons. The story of Li Ping is given in this passage mainly to ______. A．tell us the hardship of life B．tell us the fragility of life C．tell the cruelty of SARS D．tell us the joy of life
