188. Is it difficult for you to get up in the morning？ Do you sometimes oversleep？ Are you often late for work or school？ Yes？ Then Hiroyuki Sugiyama of Japan has a special bed for you. Hiroyuki’s bed will get you up in the morning! Here is how it works: The bed is connected to an alarm clock. First, the alarm clock rings. You have a few minutes to wake up. Next, a tape recorder in the bed plays soft music or other pleasant sounds. A few minutes later, a second recording plays. The second recording can be loud music or unpleasant sounds. If you don’t get up after the second recording, you’ll be sorry. A mechanical “foot” is in the bed. The mechanical foot kicks you in the head. Then the bed waits a few more minutes. What! You’re still in bed! Slowly, the top of the bed rises higher and higher. The foot of the bed goes lower and lower. Finally, the bed is vertical. You slide off the bed and onto the floor. You are awake and out of bed. Hiroyuki made his bed because he wanted to win a contest. He works for Honda Motor Company. Once every two years, Honda has a contest—the “All Honda Idea Contest”. In 1996 Hiroyuki won a prize for his bed. [共5题] (1) The purpose of the passage is ________.

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．They appear to demonstrate parasitic behavior. B．Their behavior. can be both harmless and helpful. C．They derive various benefits from their hosts. D．Researchers have inadequate observational equipment.

A.People don"t pay attention to their health. B.Few people are willing to support travel medicine. C.Most travellers firmly believe that they will be safe. D.Health comes last compared with others.

There was a certain artist who was always very careful to pay the proper amount. One year, after posting his check as usual, he began to wonder if he had paid enough, and after a lot of work, with a pencil and paper, he decided that he had not.He believed that he owed the government something. He was just writing another check to send to the tax-collector when the postman dropped a letter into the box at the front door.Opening it, the artist was surprised to find inside it a check for five pounds from the tax-collector.The official explained that too much had been paid, and that therefore the difference was now returned to the taxpayer. 21.It is mentioned in the passage that one has to pay tax according to().
