Question

【題目】閱讀理解
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】本文主要內容：我們知道電腦在工作的時候，會產生很多熱量，原來這些熱量都是直接散發(fā)到空氣中。但是后來荷蘭的一個公司研制了一種新型散熱器，它一方面可以給電腦散熱，另一方面，它能把電腦散發(fā)的熱量再次使用，給家庭供暖。
（1）A考查語境理解題�！締栴}】在電子散熱器出現(xiàn)之前，通常計算機產生的熱____________。根據(jù)短文前兩段中These systems send the heat into the air.可知，由于電腦在工作的時候會發(fā)熱，所以一些大型的計算機公司需要冷卻系統(tǒng)，使計算機冷卻下來，把熱量發(fā)送到空氣中。由此可知選A。
（2）B考查語境理解題。【問題】電子散熱器主要用于__________。根據(jù)短文第三段的內容可知，e-radiator是電子散熱器，它是一個加熱系統(tǒng)，一方面給家里提供熱量。另一方面可以使計算機冷卻。由此可知選B。
（3）D考查語境理解題�！締栴}】這個系統(tǒng)可以一個月節(jié)省用戶多少錢？根據(jù)最后一段最后一句It says the system could save its users about $440 a year.可知一年節(jié)約用戶440元，一個月節(jié)約用戶440/12=36$；故選D。
（4）C考查主旨理解題�！締栴}】這篇文章的題目是“_____”。這篇短文給我們講述的是一種新型的散熱器，它一方面可以給電腦散熱，另一方面，它能把電腦散發(fā)的熱量再次使用，給家庭供暖。因此B選項A New Way to Heat Homes供暖的新方法這個題目比較能概括短文大意，故選C。
