【正文】 agree on the answers. Calment lived to 122, so it wouldn39。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 couldn39。t live past 110. When Calment blew past that age, they raised the number to 120. So why can39。t we go higher? The trouble with guessing how old people can live to be is that it39。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. Won39。t new antiaging 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(有彈性的), 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 fly39。s never going to live 150 years. Of course, if you became a new species (物種), one that ages at a slower speed, that would be a different story, he adds. Does Martin really believe that humans could evolve (進(jìn)化)their way to longer life? It39。s pretty cool to think about, he says with a smile.（1）What does the story of Jeanne Calment prove to us? can live to 122. people are creative. are sporty at 85. live longer than men.（2）According to Steve Austad at the University of Texas, ______. average human life span could be 110 cannot find ways to slow aging people can expect to live to over 150 are not sure how long people can live（3）Who would agree that a scientist will bee famous if he makes the wildest guess at longevity?

There are ways to help kids eat healthily and avoid involving many fights at the dinner table. Jane E. Brody wrote an article for The New York Times in August 2015. The articled title is Another Approach to Raising Healthy Eaters. In this article, she shares her experience as a child who was a picky eater. She provides some useful views for parents who have children that are very picky about what foods they will eat. It turns out that demanding (要求)that a child eat something doesn39。t really work well. The mand to clean your plate can end up teaching children that it is normal to continue eating after their stomach is full. This habit may continue into adulthood and can lead to overweight bodies or food disorders. Instead, parents can try other methods that might actually influence their children to try new foods. One very simple method is to offer your children a small amount of newly introduced food. A large amount can seem intimidating (令人生畏的).One or two bites might feel less scary to try. Another really easy thing parents can do is to read the ingredients (成分）on food instructions. You might be surprised by the kinds of food that have some form of sugar added to them. One way to be a healthier eater is to reduce the amount of sugar a person eats. Read the ingredient labels, and pick a product that doesn39。t have extra sugar added. Start making your own type of your child39。 s favorite foods at home instead of buying processed (加工過的)ones. Consider organic foods over the popular, wellknown foods that are full of sugar. Sometimes, all it takes to get a child to eat healthily is to offer a food in a different way. Kids that hate raw cauliflower (菜花)might eat it after the vegetable is roasted. It is possible to turn a head of cauliflower into rice. It looks the same and your child may not notice the difference between it and real rice.（1）What do we know about Jane E.
