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 to the human life span ? 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 , 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 , one that ages at a slower speed, that would be a different story, he adds. Does Martin really believe that humans could evolve their way to longer life? "It's pretty cool to think about, "he says with a smile. Question: According to Steve Austad at the University of Texas, _ . Options: 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

Read the article and select the best answer. Article: Philip was a nine-year-old boy in a Sunday school class of 8-year-old girls and boys. Sometimes the third graders didn't welcome Philip into their group and usually tricked him. This was not because he was older, but because he was "different". You see, Philip suffered from a _ called Downs's Syndrome. This made him "different", with his facial characteristics, slow responses and mental problems. One Sunday after Easter, the Sunday school teacher gathered some plastic eggs that pulled apart in the middle. The teacher gave one to each child. On that beautiful spring day, the children were to go out and discover for themselves some symbol of "new life" and place it inside the plastic eggs. After the children returned to the classroom, the teacher opened their eggs one by one, asking each child to explain that symbol of "new life". The first opened egg contained a flower. Everyone cheered. In another was a butterfly.... When the teacher opened the last egg, it was empty. "That's stupid," said someone. The teacher felt a pull at his shirt. It was Philip. Looking up, Philip said, "It's mine. I did it. It's empty. I have new life, because the tomb is empty." Not a sound was heard in class at all. From that day on, Philip became a real part of the group. They welcomed him, and whatever made him different was never mentioned again. Philip's family knew he wouldn't live a long life, for there were too many things wrong with him. Question: After Philip explained his new life, _ . Options: A: The class thought he was clever. B: The class fell silent. C: He began to study in the class. D: He felt dying.

B

Read the article and select the best answer. Article: One day,Mr.Arnold was teaching a lesson,and things were going as normally as ever.He was explaining the story of mankind to his pupils.He told them that,in the beginning,men were nomads ;they never stayed in the same place for very long.Instead,they would travel about,here and there,in search of food,wherever it was to be found. And when the food ran out,they would move off somewhere else. He taught them about the invention of farming and keeping animals.This was an important discovery,because by learning to cultivate the land,and care for animals,mankind would always have food steadily available.It also meant that people could remain living in one place,and this made it easier to set about tasks that would take a long while to complete,like building towns,cities,and all that were in them.All the children listening were attracted by this story,until Lucy jumped up: "And if that was so important and improved everything so much,why are we nomads all over again,Mr.Arnold?" Mr.Arnold didn't know what to say. Lucy was a very intelligent girl.He knew that she lived with her parents in a house,so she must know that her family were not nomads;so what did she mean? "We have all become nomads again," continued Lucy."The other day,outside the city,they were cutting the forest down. A while ago a fisherman told me how they fish.It's the same with everyone:when there's no more forest left, the foresters go elsewhere,and when the fish run out, the fishermen move on.That's what the nomads did,isn't it?" The teacher nodded,thoughtfully. Really,Lucy was right. Mankind had turned into nomads. Instead of looking after the land in a way that we could be sure it would keep supplying our needs,we kept developing it until the land was bare.And then off we would go to the next place! The class spent the rest of the afternoon talking about what they could do to show how to be more civilized. The next day everyone attended class wearing a green Tshirt,with a message that said,"I am not a nomad!" And,from then on,they set... Question: In the teacher's opinion,Lucy's argument was _ . Options: A: reasonable B: ridiculous C: puzzling D: shocking
