【题目】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 (系统). These systems send the heat into the air.

A company in Holland (荷兰) 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 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.节能

B.实验

C.仪器

D.开关

【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

【答案】

【1】A

【2】D

【3】C

【4】B

【解析】

试题解析:本文主要讲述了科学家研究者们通过研制一种设备仪器,利用电脑运转过程中所散发出来的热量来提供热能,从而达到循环利用能源,节省能源的目的。

【1】细节理解题。根据第二段中的最后一句These systems send the heat into the air,可知A选项的意思与之相符。故选A。

【2】细节理解题。根据第四段中的e-Radiator works as a heating system,可知应选C。

【3】词义猜测题。分析device一词所在的语境,可知在此词后有一个破折号,而其后再介绍了这种新的发明,因此可推它的意思是:设备或仪器。故选C。

【4】标题判断题。纵观全文,可知本文主要讲述了科学家研究者们通过研制一种设备仪器,利用电脑运转过程中所散发出来的热量来提供热能,从而达到循环利用能源,节省能源的目的,故选B。

【题目】根据短文内容的理解,选择正确答案。Tuesday, Jan. 6, 9:50 p.m.
We were sitting in our warm living room. The TV was on, and everything was peaceful. Suddenly the light went on and off for a few times and then went out completely. Then the rain started, and everything went black. We found the flashlight and some candles and went to bed.
Wednesday, Jan. 7, 7:30 a.m.
My first thought after waking up was that it was pretty cold in my bedroom. Clearly, the power (电力供应) didn't come back. After I looked out of the window, I felt even sadder: it was still raining heavily. The room was becoming colder and colder. We had no idea when the power would come back, so my wife started a fire in the fireplace.

The snow started. The poor trees now had to carry the heavy snow. The storm seemed to last (持续) and we had nothing to do but stay at home.

Still no power. Even though we lit (点燃) a few candles, it was still difficult to do anything in their weak light. I was sitting near several candles, but I had trouble reading.
Saturday, Jan. 10, 1:00 p.m.
The storm stopped this morning, and I drove my car to look for an open store. The trees along the roads were broken. I only bought the most necessary things: bread, some fruit, more drinking water and batteries (电池) for the flashlight. On my way home, the power came back and people were very happy.

【题目】根据短文理解,选择正确答案。
Some people remember the things by writing notes to themselves. Then they leave the notes in obvious(明显的) places, such as on the table or on the floor in the middle of the living room. I don't think I like to write notes to myself. Most of the time I lose them or forget to look at them until it's too late. I prefer to use an alarm clock to tell me what I should do. I have ten alarm clocks in my house. They could tell me about things. For example, if I have to make a telephone call at a certain time, I'll set an alarm clock to go off a few minutes early and put the clock by the telephone. Or if I want to watch a certain television program, I'll set an alarm clock at the right time and put the clock on top of the TV set. I can remember almost anything if I use my clocks. However, sometimes an alarm clock goes off and I don't know what it means. I always remember setting it, but I do not know why I set it. If the clock is by the telephone, I know I may have set it to tell me to call someone, but I can't be sure. I might have set it to tell myself that somebody was to call me at a certain time.
