Question

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".

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（納米技術(shù)）make 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 specialize in ageing 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 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(老齡學(xué)) Center. "At present people who could get to that point are not in good health at all."

A．they believe that there is no limit of living

B．they are sure to find the truth about long living

2.Donald Louria's attitude towards long living is that ________.

A．people can live from 120 to 180 years

B．it is still doubtful how long humans can live

C．the human body is designed to last about 120 years

D．it is possible for humans to live longer in the future

3.The underlined "it"（paragraph 4）refers to ________.

A．a(chǎn) great push

B．the idea of living beyond the present life span

C．the idea of living from 200 to 300 years

D．the conservative estimate

4.A

【解析】

試題分析：本文是一篇科技說明文。文章就“人的壽命是否可以更長”科學(xué)家發(fā)表了不同方面的意見。

1.C推理判斷題。第二段Michaed Zey教授說 “我認(rèn)為我們正在敲擊永生之門，保守的估計(jì)，到2075年我們就會(huì)看到它的曙光”。由此可知他們有關(guān)于長生不老的一些想法。

2.D推理判斷題。由第三段可知Donald Louria 對待長生的態(tài)度是樂觀的，他認(rèn)為在將來人們有長壽的可能�？梢曰�120～180歲甚至更久，200～300歲。A項(xiàng)表述得太具體。

3.B 詞義猜測詞題。文章的前三個(gè)自然段講述一些專家認(rèn)為利用納米和基因技術(shù)可以延長人類壽命，第四段則以However, many scientists who specialize in aging are doubtful about it…一句開頭，轉(zhuǎn)折說明許多科學(xué)家對此提出質(zhì)疑，所以這個(gè)it指的是上文提出的觀點(diǎn)。

4.A主旨大意題。通讀短文可知全文都在談?wù)撊祟愂欠窨梢愿�長壽的問題。部分專家學(xué)者很樂

觀，也有部分專家并不這樣看好。A項(xiàng)正好概括了這兩個(gè)方面。文章雖提到了科學(xué)，技術(shù)，但它們只

是作為人類可以長壽的論據(jù)出現(xiàn)的。因此B項(xiàng)不對。C項(xiàng)只是部分人的觀點(diǎn)。
