Question

【题目】阅读理解
A computer can get very hot when it works on a lot of programs. It can cost a lot to cool the computer. So some scientists want to know what would happen if the heat from the computer could be used.
Large Internet companies 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. These systems send the heat into the air.
A company in Holland thinks paying to make the computers 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 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 help Microsoft
B.to provide heat
C.to heat the computer
D.to drive the computer
（3）How much could the system save its users a month?
A.About 20 dollars.
B.About 440 dollars.
C.About 36 yuan.
D.About 36 dollars.
（4）The best title of the passage may be “_____”.
A.An Environment Problem
B.The Future Computers
C.A New Way to Heat Homes
D.The Energy to Be Wasted

Answer 1

【答案】
（1）A
（2）B
（3）D
（4）C
【解析】本文主要内容：我们知道电脑在工作的时候，会产生很多热量，原来这些热量都是直接散发到空气中。但是后来荷兰的一个公司研制了一种新型散热器，它一方面可以给电脑散热，另一方面，它能把电脑散发的热量再次使用，给家庭供暖。
（1）A考查语境理解题。【问题】在电子散热器出现之前，通常计算机产生的热____________。根据短文前两段中These systems send the heat into the air.可知，由于电脑在工作的时候会发热，所以一些大型的计算机公司需要冷却系统，使计算机冷却下来，把热量发送到空气中。由此可知选A。
（2）B考查语境理解题。【问题】电子散热器主要用于__________。根据短文第三段的内容可知，e-radiator是电子散热器，它是一个加热系统，一方面给家里提供热量。另一方面可以使计算机冷却。由此可知选B。
（3）D考查语境理解题。【问题】这个系统可以一个月节省用户多少钱？根据最后一段最后一句It says the system could save its users about $440 a year.可知一年节约用户440元，一个月节约用户440/12=36$；故选D。
（4）C考查主旨理解题。【问题】这篇文章的题目是“_____”。这篇短文给我们讲述的是一种新型的散热器，它一方面可以给电脑散热，另一方面，它能把电脑散发的热量再次使用，给家庭供暖。因此B选项A New Way to Heat Homes供暖的新方法这个题目比较能概括短文大意，故选C。
