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.

听力原文：When you have a dog it is necessary to care for it very carefully. In return you will be loved by your dog.
The most important part of dog-care is cleanliness. Not only does the dog have to be kept clean, but his environment should also be clean. The bed he sleeps in can be made with anything like a rug or a dog mattress.
Proper feeding is also important for your dog's health. A dog should be fed in the same place and on a regular schedule. If your dog refuses to eat, don't force him. Remove his food and don't feed him again until his next regular feeding. Food should never be left before a dog for more than 30 minutes.
One important thing that many dog owners forget is exercise for the dog. Vigorous exercise helps build strength and keeps the dog healthy. A regular walk at a fixed time of the day is enough to help a smaller dog live a healthier end happier life. Large dogs, though, require a run in an open fid&
There are other things that are also important for a dog's health — things like bathing, care of the teeth and nails, keeping them away from insects as much as possible. But if you observe the three main points covered above, your dog will give you a great amount of pleasure.

Two People，Two Paths You must be familiar with the situation：Dad’s driving，Mum’s telling him where to go.He’s sure that they need to turn left But she says it’s not for another two blocks.Who has the better sense of direction？ Men or women.
They both do, a new study says.but in different ways.Men and women.Canadian researchers have found，have different methods of finding their way.Men look quickly at landmarks(地标)and head off in what they think is the right direction.Women, however, try to picture the whole route in detail and then follow the path in their head.“women tend to be more detailed,”said Edward Cornell.who led the study,“while men tend to be a little bit faster and …a little bit more intuitive(直觉感知的).”
In fact, said Cornell,“sense of direction”isn’t one skill but two.
The first is the“survey method”.This is when you see all area from above, such as a printed map.Y0u can see，for example，where the hospital is，where the church is and that
the supermarket is on its right.
The second skill is the“route method”This is when you use a series of directions.You start from the hospital，then turn left，turn fight，go uphill——and then you see the
supermarket.
Men are more likely to use the survey method while women are more likely to use one route and follow directions.
Both work, and neither is better.
Some scientists insist that these different skills have a long history. They argue it is because of the difference in traditional roles.
In ancient times，young men often went far away with the older men to fish or hunt.The trip took hours or days and covered unfamiliar places.The only way to know where you were was to use the survey method to remember landmarks—them ountains, the lakes and so on.
The women，on the other hand，took young girls out to find fruits and plants.These activities were much closer to home but required learning well-used paths.So, women’s sense of space was based on learning certain routes.
第41题：When finding his way, Dad tends to rely on
A．his intuitive knowledge.
B．his book knowledge．
C．Mum’s assistance.
D．the police’s assistance．
