D

We all wish we could get by on less sleep, but one father and son actually can—without suffering any health consequences and while actually performing on memory tests as well as,or better than, most people.

To understand this rare ability, researchers at the University of California, San Francisco, first identified a genetic mutation(基因突变）-in both individuals-that they thought might deserve the credit. Then the scientists intentionally made the same small genetic spelling mistake in mice. The mice also needed less sleep, remembered better and suffered no other ill effects, according to a study published recently in Science Translational Medicine.

But according to Jamie Zeitzer, an associate professor at Stanford University, although a medication with the same benefits will not be available anytime soon- and might never come true-the idea is incredibly appealing: take a pill that copies whatever the father and somebody does and sleepless, with no negative effects. But he also worries that even if a drug like this could be produced without causing significant side effects, it would still have social consequences. Some individuals might be forced or pressured to take medication so they could work more hours. Even if people will not need as much sleep, they will still need to have a rest, he insists.

The study's senior author, Ying-Hui Fu, a professor at U. C. S. F. says it is far too early for such fantasies. Instead she is interested in better understanding the mechanisms(机制) of healthy sleep to help prevent diseases ranging from cancer to Alzheimer’s. “These people sleep more efficiently ,” she says of the father-son pair.” Whatever function sleep is doing for us, it takes us eight hours to feel rested, but it takes them six or four hours. If we can figure out why they are more efficient, we can use that knowledge to help everybody to be more efficient."

12.Why do the scientists make the research in mice?

A. To invent a kind of new pill.B. To test the functions of the pill.

C. To identify the cause of the rare ability.

D. To find out the side effects of the rare ability

13.What does Zeitzer think of the idea of producing the drug?

A. It's bound to come true.B. It's a great brainstorm.

C.It's absolutely unrealistic .D. It's a double-edged sword.

4.What's the benefit of studying the mechanisms of sleep?

A. Curing some diseases.B. Changing sleep patterns.

C. Keeping off some diseases.D. Improving the working efficiency.

15.What can we infer from the text?

A. The drug will soon be in produced.

B. The research still has a long way to go.

C. The process of producing the drug is rather complicated.

D. The reason why the father-son pair need less rest has been figured out.
