Cooling the servers can becostly. So researchers asked what would happenif the heat created by the servers could be captured and used?Data centers oflarge Internet companies such as Google and Microsoft have thousands ofcomputer servers. As these servers process information, they create largeamounts of heat, so they need huge cooling systems. These systems send the heatinto the air. The Dutch company Nerdalize thinks paying for electricity tooperate the servers and then paying again to cool them is a waste of energy. Soit developed a device called the e-Radiator. It is a computer server that alsoworks as a heating source. Boaz Leupe is the chief executive officer ofNerdalize. He says the e-Radiator saves money because companies don't have topay to cool their servers."The kilowatt（千瓦）hour you are using is usedtwice -- once to heat the home and once to compute the client's task withoutthe cooling overhead." He says five homeowners in the Netherlands aretesting the heating device in their homes. "We reimburse the electricitythe server uses, and that we can do because of the computer clients on theother side, and, in that way, homeowners actually get heating for free, andcomputer users don't have to pay for the overhead of the data center."JanVisser is one of the participants in the year-long experiment. He says theamount of heat produced by the e-Radiator depends on the work being done by thecomputer server. He says it cannot be used as the primary source of heat. Buthe is ready to try it.He says if it provides enough warmth, he will be able touse his home's heating system less, which will save him money. Nerdalize sayse-Radiators create heat temperatures of up to 55℃. It says the devices couldsave users up to $440 in heating costs a year. Why did researchers ask whatwould happen if the heat created by the servers could be captured and used? A.Because computers can get very hot.B. Computer servers is a complex program.C.Cooling computer servers costs a lot of money.2.The computer servers in largeInternet companies such as Google and Microsoft can .A. create large amounts ofinformationB. create large quantity of heatC. manage the huge cooling systems3.Nerdalize developed the e-Radiator because .A. e-Radiator cost less energyB.e-Radiator can cool the servers for freeC. e-Radiator can create cold air forfree4.According to Jan Visser, the amount of heat produced by the e-Radiator.A. depends on the work being processed by PCB. cannot be used as the home'sheating systemC. cannot be used as the main source of heat5.The best title forthis passage is A. The New Way to Heat HomesB. The New Way to Cool HomesC. HotComputers Could Be Used for Free答案:C# B# B# C# A
