Question

Do you want to live another 100 years or more? Some experts say that scientific progress will one day help humans to last tens of years longer than what is now seen as the natural limit（限制）of the human life span（壽命）.
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate（保守估計）.”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said progress in using genes as well as nanotechnology（納米技術）makes it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who research into aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also disagree on what kind of life the super aged might live. “It remains to be seen whether you could be healthy enough to have good quality of life when you pass 120.” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”

Answer 1

 
【小題1】C
【小題2】D
【小題3】B
【小題4】A

解析試題分析：本文講述的是科學家在研究人類是否能夠活得更長更健康，以及不同的人對此問題的不同的反應。
【小題1】C 推理題。根據本句we are knocking at the door of immortality (永生),指我們敲響了永生的門，說明我們已經了解到了一些關于永生的秘密，結合第一段內容可知C正確。
【小題2】D 細節題。根據第二段最后3行“ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years說明他認為人類永生是有可能的，故D正確。
【小題3】B 推理題。這里的it就是指上一段里的“ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.活的時間超過現在的預測。故B正確。
【小題4】A 主旨大意題。本文討論的主要就是人類在未來是否可以活的更久一點，故A項正確。
考點：考查科普類短文閱讀
點評：對于人類是否可以活得更為久遠，文章中給出了答案。屬于科普類的短文，此類文章的最大的障礙是詞匯以及考生對閱讀內容的不熟悉，需要考生在閱讀的時候有足夠的耐心。要養成在上下文串聯中猜測詞義的能力，根據上下文中出現的同義詞，近義詞，反義詞，以及詞義的解釋來理解生詞。同時要抓住文章的中心，不要受其他信息的影響。要根據題目及選項以及文章的上下文串聯合理的判斷推理。
