Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins. Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes. "This is the first indication that these effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C.. No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says. If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective. But Spindler isn't sure the trade-off is worth it. "The mice get less disease, they live longer, but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'." Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction.

We must consider that of desires some are natural, others vain, and of the natural some are necessary and others merely natural; and of the necessary some are necessary for happiness, others for the repose of the body, and others for very life. Unhappiness comes either through fear or through vain and unbridled desire; but if a man curbs these, he can win for himself' the blessedness of understanding. Of desires, all that do not lead to a sense of pain, if they are not satisfied, are not necessary, but involve a craving which is easily dispelled, when the object is hard to procure or they seem likely to produce harm. Wherever in the case of desires which are natural, but do not lead to a sense of pain, if they are not fulfilled, the effort is intense, such pleasures are due to idle imagination, and it is not owing to their own nature that they fail to be dispelled, but owing to the empty imaginings of the man. The disturbance of the soul cannot be ended nor true joy created either by the possession of the greatest wealth or by honour and respect in the eyes of the mob or by anything else that is associated with causes of unlimited desires. We must not violate nature, but obey her; and we shah obey her if we fulfil the necessary desires and also the natural, if they bring no harm to us, but sternly reject the harmful. The man who follows nature and not vain opinions is independent in all things. For in reference to unlimited desires even the greatest wealth is not riches but poverty. Insofar as you are in difficulties, it is because you forget nature; for you create for yourself unlimited fears and desires. It is better for you to be free of fear lying upon a pallet, than to have a golden couch and a rich table and be full of trouble. What does "greater discomfort accrues to us" in Paragraph 1 mean here？ A．We get greater discomfort over a period of time. B．We are tortured by greater discomfort. C．Greater discomfort exists in our body. D．Greater discomfort makes us miserable.

Other people feel sure that the present trend is towards too little sleep. To quote one medical opinion, "Thousands of people drift through life suffering from the effects of too little sleep; the reason is not that they can't sleep. Like advancing colonists, we do seem to be grasping ever more of the land of sleep for our waking needs, pushing the boundary back and reaching, apparently, for a point in our evolution where we will sleep no more. This in itself, of course, need not be a bad thing. What could be disastrous, however, is that we should press too quickly towards this goal, sacrificing sleep only to gain more time in which to jeopardize our civilization by actions and decisions made weak by fatigue. Then, to complete the picture, there are those who believe that most people are persuaded to sleep too much. Dr. H. Roberts, writing in Every Man in Health, asserts it may safely be stated also. It would be a pity to retard our development by holding back those people who are gifted enough to work and play well with less than the average amount of sleep, if indeed it does them no harm. If one of the trends of evolution is that more of the life span is to be spent in gainful waking activity, then surely these people are in the van of this advance. The author seems to indicate that ______. A．there are many controversial issues like the right amount of sleep B．among many issues the right amount of sleep is the least controversial C．people are now moving towards solving many controversial issues D．the right amount of sleep is a topic of much controversy among doctors

It's always a good idea to put on your seat belt when you're in a car. Why？ Think about this example: You put an egg on a skateboard(滑板) and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break. Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying. It will stay safely on the skateboard. Volvo, a famous Swedish carmaker, was the first to use seat belts in 1949. Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most newer cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly--in less than one second--to keep the people inside safe. B-21. We have to be careful in driving a car mainly because it could be _____. A、little fun B、a pleasure C、a lot of trouble D、a great danger B-22. The example of an egg on a skateboard is used to show that _____. A、eggs break easily on a moving skateboard B、cars should not be stopped suddenly C、seat belts are important to safety D、driving is a dangerous act B-23. Which of the following statements is TRUE？ A、People with seat belts tied will always be safe in cars. B、Volvo was the first carmaker to use seat belts in cars. C、Air bags will come out before the cars hit something. D、All cars have air bags in front of the seats. B-24. According to the passage, air bags are another device that _____. A、adds safety to car driving B、is going to replace seat belts C、comes out slowly to function D、prevents cars from running too fast B-25. The best title for this passage is _____. A、Buy a Volvo with Air bags B、Make a Car Safe Inside C、Fasten Your Seat Belts D、Add Air Bags to Cars
