Question

ÔĶÁÀí½â ¡¡¡¡She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday£® ¡¡¡¡When it comes to long life, Jeanne Calment is the world¡¯s record holder£®She lived to the ripe old age of 122£®So is 122 the upper limit to the human life span(ÊÙÃü)?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 surprise 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 much 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 120£®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 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 us kicking until about 120£®Researchers are working on treatments that lengthen the life span of mice by 50 percent at most£®So, if the average human life span is about 80 years, says Miller, ¡°adding another 50 percent would get you to 120£®¡± ¡¡¡¡So what can we conclude from this little disagreement among the researchers?That life span is flexible(Óе¯ÐÔµÄ), 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¡¯s never going to live 150 years£®¡± Of course, if you became a new species(ÎïÖÖ), one that ages at a slower speed, that would be a different story, he adds£® ¡¡¡¡Does Martin really believe that humans could evolve(½ø»¯)their way to longer life? ¡°It¡¯s pretty cool to think about, ¡±he says with a smile£® (1) What does the story of Jeanne Calment prove to us? [¡¡¡¡] A£® People can live to 122£® B£® Old people are creative£® C£® Women are sporty at 85£® D£® Women live longer than men£® (2) According to Steve Austad at the University of Texas, ________£® [¡¡¡¡] A£® the average human life span could be 110 B£® scientists cannot find ways to slow aging C£® few people can expect to live to over 150 D£® researchers are not sure how long people can live (3) Who would agree that a scientist will become famous if he makes the wildest guess at longevity? [¡¡¡¡] A£® Jerry Shay£® B£® Steve Aust C£® Rich Miller D£® George Martin (4) What can we infer from the last three paragraphs? [¡¡¡¡] A£® Most of us could be good at sports even at 120£® B£® The average human life span cannot be doubled£® C£® Scientists believe mice are aging at a slower speed than before£® D£® New techniques could be used to change flies into a new species£®
