Experts say that students usually need eight to ten hours' sleep at night，but more Chinese students do not get enough sleep．Some Chinese parents are usually glad to see their children studying late．They will think their children work very hard．But not all parents are happy about this．Once a mother told us that every morning her 10-year-old boy put up one finger with his eyes still closed，begging(央求)for one more minute to sleep．Like thousands of student“early birds” in China，he has to get up before six every morning．
A report shows that without a good night's sleep，students seem to be weaker than they should be．Many students have fallen asleep during class at one time or another．Too much homework is not the only reason why students stay up late．Some watch TV or play the computer games late into the night．
Experts have ever said that students should develop good study habits．So some clever students never study late，they are able to work well in class．

Television is good．You'd like to watch it all day and all night．But don't! Too much TV is a very bad thing, especially for kids．
Scientists(科学家)found that kids who watch too much TV may have more trouble learning to read than other kids．They can't focus(集中)on their work．
Kids learn language skills best by reading, talking and playing with others．If they spend too much time watching TV, they'll have less time for those things．It may make it harder for them to get on with others when they grow up．

Jeanne Calment took up skating at age 85, made her first movie appearance at age114．and held a concert in the neighborhood on her 121 st birthday．
When it comes to long life, Jeanne Calment is the world’s recordholder．She lived to the ripe old age of 122．So is 122 the upper limit(限制)to the human life span(寿命)?If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150－or beyond?
Researchers don't entirely agree on the answers．“Calment lived．to 122, SO it wouldn't sul33rise me if someone alive today reaches 130 or 135,”says Jerry Shay at the University of Texas．
Steve Austad at the University of Texas agrees．“People can live longer than we think．”he says．“Experts used to say that humans couldn’t live past 110．When Calment blew past that age, they raised the number to 1 20．So why can’t we go higher?”
The trouble with guessing how old people can live to be is that it’s all just guessing．“Anyone can make up a number．”says Rich Miller at the University, of guessing
Michigan．“Usually the scientist who picks the highest number gets his name in Time magazine．”
Won’t new anti－aging techniques keep us alive for centuries?Any cure, says Miller, for aging would probably keep most of HS living until about 120．Researchers are working on treatments that make the life span of mice longer by 50 percent at most．
So, if the average(平均)human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120．”
So what can we learn from this little disagreement among the researchers?That life span is flexible(有弹性的), but there is a limit, says George Martin of the University of Washington．“We can get flies to live 50 percent longer．”he says．“But a fly'snever going to live 150 years．”Of course, if you became a new species(物种), one that ages at a slower speed, that would be a different story, he adds．
Does Martin really believe that humans could evolve(进化)their way to longer life?“It’s pretty cool to think about．”He says with a smile．

few people can expect to live to over 150
D．
experts aren’t sure how long one can live
(3)
Who thinks that a scientist will become famous if he makes longevity?
[ ]
A．
Jerry Shay．
B．
Steve Austad．
C．
Rich Miller．
D．
George Martin．
(4)
What can we infer from the last three paragraphs?
