A meager diet may give you health and long life, but it's not much fun—and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don't start to diet until old age.
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.
According to the passage, which of the following is NOT true？
A．Eating less than usual might make us live longer.
B．If we go on a diet when old, we may keep healthy.
C．Dieting might not be needed. ~
D．We have to begin dieting from childhood.

Even a carefui motorist may have the misfortune to...
Even a carefui motorist may have the misfortune to commit a motoring__ 21__ .In due course. having received a summons (传票), he will appear in a police court. In the court,the motorist hears his name called by the clerk of the court, and cormes forward to_ 22__himself. The magistrate (地方法官) then calls for the policeman who_ 23__ the offender and asks him to give evidence. The officer takes the oath to tell the truth, the whole truth, and nothing but the truth. He also is expected to give an account__ 24 __what happened when the offence was committed and to mention any special circumstances. For instance the offence__ 25__partly due. to the foolishness of another motorist, It would be unwise for the accused motorist to exaggerate this. It will not help his case to try to blame__26_ for his own mistake. The magistrate, __27_ hearing that some other motorist is invoived, willl doubtless say:What is being done about this man？ "Case coming up later this afternoon, may_ 28_ be the answer. __29__ you are guilty, it is of course wise to plead and apologize for committing the offence and__ 30__ the court&39;s time, Magistrates are not heartless and a motorist may be lucky enough to hear one say:"There are mitigating circumstances, __31__ you have broken the law and I am obliged to impose a fine. Pay five pounds. Next case ". __32_ many of-fences,if you wish to plead guilty you may do so by post and ,avoid__33__ the court at all. Some. shor-tempered people forget that both policemen and magistrates have a public duty to_34 _and arerude to them. This does not pay :and rightly so! A magistrate wil not let off an offender 35 because he is respectable, but the courteous (有礼貌的) lawbreakers may certainly hope that the magistrate will extend to him what tolerance the law permits.
