Question

    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.

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 system(系統(tǒng)) Thes 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 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°C. It says the system could save its users about$ 440 a year.

53. The e-Radiator is mainly used .

   A. to drive the computer

   B. to help Microsoft

   C. to heat the computer

   D. to provide heat

54. The Chinese meaning of the word "device" in this passage is probably "".

   A. 節(jié)能   B. 實(shí)驗(yàn)   C. 儀器   D. 開關(guān)

55. The best title of the passage may be""

   A. An Environmental Problem

   B. A New Way to Heat Homes

   C. The Future Computers

   D. The Energy to Be Wasted

Answer 1

53. D 54. C 55. B

[閱讀D篇短文大意]本文是關(guān)于e-Radiator的介紹。這是 荷蘭的一家公司研發(fā)出來的一種特殊的儀器，它能夠把電腦散發(fā) 出來的熱量充分利用，用它來使家里變得暖和。

53. D 由第四段中的"... the e-Radiator works as a heating system

and saves money "以及第七段中的"... the e-Radiator produces more heat” 可推斷答案為D.

54. C通讀第三段可知，e-Radiator是這家公司研發(fā)出來的一種特殊的儀器，故答案為C.

55. B通讀全文可知，適合本文的最佳標(biāo)題是B項(xiàng)。
