【正文】 he 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? Shay. Austad. Miller. Martin.（4）What can we infer from the last three paragraphs? of us could be good at sports even at 120. average human life span cannot be doubled. believe mice are aging at a slower speed than before. techniques could be used to change flies into a new species【答案】 （1）A（2）D（3）C（4）B 【解析】【分析】本文是一篇說明文，介紹了科學(xué)家對長壽的不同觀點(diǎn)和對延長人的壽命的不同理解。 （1）考查細(xì)節(jié)理解。根據(jù)第二段中的“Jeanne Calment is the world39。s recordholder. She lived to the ripe old age of 122. ”說明人們可以活到122歲，故選A。 （2）考查細(xì)節(jié)理解。文章第四段中 的“People can live much longer than we think.”可知人類能活多長仍是未知數(shù)，故選D。 （3）考查細(xì)節(jié)理解。根據(jù)第五段中的“Usually the scientist who picks the highest number gets his name in Time magazine.，可知Rich Miller認(rèn)為科學(xué)家們，只要瘋狂的想法找機(jī)會(huì)成名，因此選C。 （4）考查推理判斷。最后三段提到了在老鼠身上做的實(shí)驗(yàn)，證明生命是可以通過抗老技術(shù)延長的，但同時(shí)又提到生命是有限度的?？茖W(xué)家通過試驗(yàn)證實(shí)人類平均壽命的跨度不能翻倍，故選B。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇健康類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。8．閱讀理解 We may be living in the digital age but reading books is still a big part of growing up. When they39。re in primary school, children read books that really challenge them. But once they reach secondary school, the level of difficulty doesn39。t change much. Secondary school students tend to read books which are also read by upper primary students. They are not challenging themselves enough. To discover these trends, I analyzed data collected by Accelerated Reader (AR) software, which asks pupils to check their understanding of the books they39。ve chosen to read. The difficulty — which I call readability. I also created two lists of books: one for the books that most secondary pupils had chosen to read, and another for the books they had voted as their favorites. According to the readability, these students39。 favorite books tend to be much more advanced than the other books they chose, but they could still understand them. The rest of the books most often chosen by them are quite simple. You might think that students who read harder books might make more mistakes and understand them less well. But students39。 quality of prehension does not depend on the difficulty of the book, no matter what year of secondary school they39。re in. Having an interest is the most obvious factor here — if you like the book, you try hard to really understand it. As children bee teenagers, they listen less to advice from adults and more to advice from kids of their age. So, rather than trying to lecture young people on the benefits of Jane Austen, we should make the nature of the problem clear to them. Students should challenge each other to read more difficult books. Adults could help by setting up noticeboards or organizing social media networks for young people to share their remendations. And teachers can lend a hand by setting aside time for reading in school. Young people will realize the problems that e when they don39。t challenge themselves to read difficult books.（1）What can we learn from the first paragraph? spend little time on afterclass reading school students seldom read tough books39。s reading interest tends to decrease as they grow up students have difficulty choosing good reading materials（2）The author made use of AR software to ________. children39。s different reading styles the average time children spend on reading out the causes of children39。s reading difficulties clear the difficulty levels of books read by children（3）What can we infer about secondary school students from the readability scores? find some advanced books interesting often make mistakes during advanced reading prefer to read books remended by their parents can hardly improve their scores on reading prehension（4）According to Paragraph 4, what is vital for improving reading prehension? knowledge skills（5）What does the author want to express in the last paragraph? relatively difficult textbooks is necessary students39。 reading is a shared responsibility technology should be used in reading reaching should be encouraged to read more literary works【答案】 （1）B（2）D（3）A（4）C（5）B 【解析】【分析】本文是一篇議論文，作者通過對初中生閱讀能力的一項(xiàng)調(diào)查討論了如何提高他們的閱讀能力—興趣動(dòng)力。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的“But once they reach secondary school, the level of difficulty doesn39。t change much. Secondary school students tend to read books which are also read by upper primary students. They are not challenging themselves enough.”但是一旦他們進(jìn)入中學(xué)，學(xué)習(xí)的難度并沒有太大的變化。中學(xué)生喜歡讀小學(xué)高年級學(xué)生也讀的書。他們沒有足夠的挑戰(zhàn)自己，可知，初中生在閱讀難度方面沒有提高。故選B。 （2）考查細(xì)節(jié)理解。根據(jù)第二段中的“To discover these trends, I analyzed data collected by Accelerated Read
