【題目】A Cloud of Hope and Danger

A small cloud floats through the air in a hospital operating room. In the room a patient, suffering from cancer, lies on a table. The cloud surrounds(包圍) the patient, covering her body and filling her lungs(). The cloud is not smoke or steam. It is made of millions of microscopic robots called nanorobots(納米機(jī)器人). These tiny robots move from cell(細(xì)胞) to cell in the patient’s body, destroying the cancer.

Fighting cancer with nanorobots is only an idea today, but scientists say that it could be possible in the future. Using nanorobots for good purposes such as fighting disease or repairing the environment may be the solution to many of today’s problems.

However, nanorobots could be a dangerous risk as well. Since nanorobots are so tiny, they will have to work in large teams of many thousands to many millions. For this reason, nanorobots will have to be programmed to build themselves. Scientists will not have the ability to build millions of nanorobots one by one.

This ability to reproduce is making some scientists worried. What if something goes wrong in the programming? Quite a lot of crazy nanorobots would be far worse than any disease. Some people think that if they get out of control, nanorobots could destroy the Earth.

What should be done? Should we continue researching nanorobots or should we search for other methods? This is one of the many difficult decisions that we have to make in the future.

1What is the cloud in the passage, smoke and steam or microscopic robots?

【答案】

1Microscopic robots.

2Fighting disease or repairing the environment.

3Because they are so tiny.

4The ability to reproduce.

5Whether we should research nanorobots or not.

6Any reasonable answer is ok.

【解析】這篇短文給我們講述的是納米機(jī)器人的使用,這是一種先進(jìn)的技術(shù),可以幫助人類治療疾病、修復(fù)環(huán)境。但同時(shí)納米機(jī)器人也有不好的一面:安裝程序之后,他們可以自己再生,如果程序出錯(cuò),就可能會(huì)產(chǎn)生可怕的后果。

1根據(jù)短文第一段中The cloud is not smoke or steam. It is made of millions of microscopic robots called nanorobots(納米機(jī)器人).可知,這團(tuán)云霧不是煙或蒸汽,它是有幾百萬個(gè)微型機(jī)器人組成的,被稱為納米機(jī)器人。故答案為Microscopic robots。

2根據(jù)短文第二段中Using nanorobots for good purposes such as fighting disease or repairing the environment may be the solution to many of today’s problems.可知,我們可以用納米機(jī)器人來戰(zhàn)勝疾病、修復(fù)環(huán)境。

3根據(jù)短文第三段中Since nanorobots are so tiny, they will have to work in large teams of many thousands to many millions.可知,因?yàn)榧{米機(jī)器人很小,所以他們必須在一個(gè) 成千上萬或幾百萬的團(tuán)隊(duì)中工作。由此可知答案。

4根據(jù)短文第三段中For this reason, nanorobots will have to be programmed to build themselves.可知,納米機(jī)器人可以自己建造自己,即reproduce,再生,復(fù)制。

5這篇短文給我們講述了納米機(jī)器人,這種機(jī)器人可以幫助人類治療疾病、修復(fù)環(huán)境,是非常有用的。但是科學(xué)家們同時(shí)也在擔(dān)心,因?yàn)檫@種機(jī)器人可以再生,如果程序出錯(cuò),會(huì)造成可怕的后果。文章的最后一段Should we continue researching nanorobots or should we search for other methods? This is one of the many difficult decisions that we have to make in the future.也提出了這樣的問題,因此這篇短文的題目還可以是Whether we should research nanorobots or not?

6這個(gè)題目問的是在未來你是支持還是反對(duì)使用納米機(jī)器人,是一個(gè)開放性的題目,答案不是固定的。首先我們應(yīng)先回答支持還是反對(duì),然后再給出理由。注意表達(dá)要準(zhǔn)確,給出的理由應(yīng)合理、重復(fù)。例如答語是支持的話,可以回答I am for using nanorobots in the future because it is useful for fighting diseases or repairing the environment.
