Do you want to live another 100 years
or more? Some experts say that scientific advances will one day enable humans to
last tens of years beyond what is now seen as the natural limit of the human
life span. "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 (保守的估计)." At the conference in San Francisco, Donald
Louria, a professor at New Jersey Medical School in Newark said advances in
using genes as well as nanotechnology (纳米技术) make it likely that humans will bye
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 specialize in ageing are doubtful about it and say
the human body is just not designed to last past 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 differ on
what kind of life the super aged might live. "It remains to be seen if you pass
120, you know; could you be healthy enough to have good quality of life?" said
Leonard Pooh, director of the University of Georgia Gerontology. Centre. "At
present people who could get to that point are not in good health at
all."
单选题
By saying "we are knocking at the door of immortality", Michael Zey means______.
【正确答案】
C
【答案解析】[解题指要] 这个小题考查学生对句子暗含意思的理解。“we are knocking at the door of immortality”中door的意思是“达到或通向某事物的门路或途径”。句子的含义是选项C所表示的 they have got some ideas about living forever.“关于如何能长生不老他们已经有了些认识”。A选项they believe that there is no limit of living的意思是“他们相信生命是无限的”，B选项they are sure to find the truth about long living的意思是“他们一定会找到长寿的真谛”，D选项they are able to make people live past the present life span的意思是“他们能够使人们超越当前的寿命”。这三个选项都与本文论述的人类是否可以长寿这一问题相关，但是都不是本题的答案。
单选题
Donald Louria's attitude towards long living is that______.
【正确答案】
D
【答案解析】[解题指要] 本题问Donald Louria对长寿的态度是怎样的。A选项people can live from 120 to 180的意思是“人们(现在)就可以活120年到180年”，这与原文意思不符。第二段第二句 There is a great push so that people can live from 120 to 180 years的意思是“为了人能活120岁到 180岁，现在开展了大规模的研究工作”。Push有“(对敌人发起)猛攻”的意思。So that引出表示目的的从句。B选项it is still doubtful how long humans can live的意思是“人类到底能活多久还不好说”。这也不是Donald Louria的观点。C选项the human body is designed to last past about 120 years“人类身体是为了能够活120岁以上而设计的”，恰恰与原文many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last past about 120 years相反。本题的答案可以从第二段第一句里找到：Donald Louria… said advances in using genes as well as nanotechnology(纳米技术)make it likely that humans will live in the future beyond what has been possible in the past.意思是“基因运用和纳米技术的发展使人们未来可能比过去活得时间更长”。也就是D选项it is possible for humans to live longer in the future所表达的意思。

What would be the best title for this text?
【正确答案】
A
【答案解析】[解题指要] 这道题问这篇文章的题目会是哪一个，考查的是对文章主旨大意的把握。需要综观全文，A选项Living Longer or Not可以反映这篇文章的主旨，因为所有的讨论都是围绕这个主题展开的。若以B选项Science，Technology and Long Living“科学、技术和长寿”为题，文章讨论的应是这三者的关系。C选项No Limit for Human Life的意思是“人类的生命是无限的”，文章中并没有人持此观点。D选项Healthy Lifestyle and Long Living的意思是“健康的生活方式与长寿”，本文未涉及健康的生活方式的内容，因此不选。
