Question

【题目】阅读理解

阅读下面的短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet(彗星). When the fragments (碎片) landed in the southern part of the grand planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?

The year is 2094. It had been announced that a comet is heading towards the earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the earth. The news has caused panic.

On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the spend of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.

Millions of people are already dead in the southern part of the earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosion. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.

Could it really happen? It has already happened more than once in the history of the earth. The dinosaur was on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?

【1】Which of the following is NOT true according to the author's description of the disaster in 2094?

A．The whole world becomes extremely cold.

B．All the coastal cities in Africa are destroyed.

C．The whole mankind becomes extinct.

D．The visit of the comet results in wars.

【2】Why does the author mention dinosaurs at the end of the passage?

A．Because they could only live in the warm climate.

B．Because they once dominated the earth.

C．Because their extinction indicates future disasters.

D．Because dinosaurs and humans never live in the same age.

【3】In writing the passage, the author intends to________.

A．give an accurate description of the possible disaster in the future

B．prove that humans will sooner or later be destroyed

C．tell the historical development of the earth

D．warn of a possible disaster in the future

【4】It can be concluded that the passage is most probably part of a(n)_______．

Answer 1

【答案】

【1】C

【2】C

【3】D

【4】D

【解析】 作者通过一段幻想的灾难和一段地球历史上出现过的恐龙绝迹的事实以及科学家们分析恐龙绝迹的原因，来警示人类未来可能发生的灾难。

【1】C 辨别正误题。据第三自然段的描述可知，A、B、D均符合本文所假想的事实，只有C不符。文中“No more than 10 million people have survived”一句意为“只有一千万人幸存下来”，而C项说全人类都灭绝了。显然与文章不符。题干要求找出不对的选项。

【2】C 推理判断题。第三段中，作者描述假想的人类灾难……最后一段提到生活在地球上的恐龙在65 million years ago突然消失(即灭绝)，许多科学家相信地球曾受到过外空星体碎片的袭击，从而导致恐龙绝种。由此暗示人类未来的灾难。

【3】D 观点态度题。本题要求考生推测作者意图。作者通过一段幻想的灾难和一段地球历史上出现过的恐龙绝迹的事实以及科学家们分析恐龙绝迹的原因，来警示人类未来可能发生的灾难。

【4】D 推理判断题。据全文大意，又据文章的性质，可判定D为最佳选项。A、B、C均不太妥当。
