Question

【題目】閱讀理解。

When a computer works on a group of programs, it can get very hot. Cooling the computer can cost a lot. So some scientists wonder what would happen if the heat from the computer could be used.

Large Internet companies (公司) such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems (系統(tǒng)). These systems send the heat into the air.

A company in Holland (荷蘭) thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a specialdevice—the e-Radiator.

Boaz Leupe, head of the company, says that e-Radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer and that the users don’t have to pay to cool their computers.

Five homeowners in Holland are testing the heating system in their homes.

“We pay for the computer using, so, in that way, homeowners get heating for free,”Boaz says.

Jan Visser is one of the homeowners. “If you use the computer more, the e-Radiator producers more heat, ”he says, “It cannot provide enough heat if you don’t use your computer often.” But he is ready to try it. It’s a great help for his family.

The company says e-Radiators produce heat temperatures of up to 55℃. It says the system could save its users about $440 a year.

【1】Before the e-Radiator appears, usually the heat of a computer ______.

A. is sent into the air B. helps the five homeowners

C. is used twice D. makes the computer work better

【2】The e-radiator is mainly used _____.

A. to drive the computer B. to help Microsoft

C. to heat the computer D. to provide heat

【3】The Chinese meaning of the word “device” in this passage is probably “____”.

A. 節(jié)能 B. 實驗

C. 儀器 D. 開關(guān)

【4】The best title of the passage may be “_____”.

A. An Environment Problem B. A New Way to Heat Homes

C. The Future Computers D. The Energy to Be Wasted

Answer 1

【答案】

【1】A

【2】D

【3】C

【4】B

【解析】試題分析：本文主要講述了科學家研究者們通過研制一種設(shè)備儀器，利用電腦運轉(zhuǎn)過程中所散發(fā)出來的熱量來提供熱能，從而達到循環(huán)利用能源，節(jié)省能源的目的。

【1】細節(jié)理解題。根據(jù)第二段中的最后一句These systems send the heat into the air，可知A選項的意思與之相符。故選A。

【2】細節(jié)理解題。根據(jù)第四段中的e-Radiator works as a heating system，可知應選C。

【3】詞義猜測題。分析device一詞所在的語境，可知在此詞后有一個破折號，而其后再介紹了這種新的發(fā)明，因此可推它的意思是：設(shè)備或儀器。故選C。

【4】標題判斷題�？v觀全文，可知本文主要講述了科學家研究者們通過研制一種設(shè)備儀器，利用電腦運轉(zhuǎn)過程中所散發(fā)出來的熱量來提供熱能，從而達到循環(huán)利用能源，節(jié)省能源的目的，故選B。
