Question

3(2015 重庆，D) 

       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 informa?tion,they produce lots of heat,so they need huge cooling systems ( 系统) .These systems send the heat into t.he air.

        A company in Holland (荷兰) thinks paying to make the com?puters work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-Radiator.

       Boaz Leupe,head of the company,says the 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 produces 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°Csays 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 prob?ably "

   A. 节能  B.实验   C. 仪器   D. 开关

4. The best title of the passage may be  

   A. An Environrnenl Problem   

    B. A New Way to Heat Homes   

    C. Tlie Future Computers   

    D. The Energy to Be Wasted

Answer 1

1. A 2. D 3. C 4. B

Passage 3

[语篇解读]这是一篇科普说明文。本文介绍了荷兰一家公司发明 了一种特殊仪器，它能充分利用电脑使用过程中散发出的热量，为家 庭供暖。

1. A细节理解题。由第二段最后一句可知答案。

2. D细节理解题。由第七段的If you use the computer more,the e-Ra-diator produces more heat 可知答案。

3. C 词义猜测题。由第四段的 the e-Radiator works as a heating system and saves money可知应该是一种特殊的仪器。

4. B主旨大意题。A. —个环境问题;   B. —种为家庭供暖的新方法;   C. 未来的电脑;   D. 将被浪费的能源。根据文章内容可知应选B.

[长难句] So some scientists wonder what would happen if the heat from the computer could be used.所以一些科学家想知道如果来自电脑的热 量能被利用起来将会发生什么事情。这是一个复合句。wonder后为what引导的宾语从句。if引导条 件状语从句。
