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﹩440a year．
32．The e-radiator is mainly used___．
A．to provide heat
B．to drive the computer
C．to heat the computer
D．to help Microsoft
33．Before the e-Radiator appears，usually the heat of a computer___．
A．makes the computer work better
B．helps the five homeowners
C．is used twice
D．is sent into the air
34．The Chinese meaning of the word"device"in this passage is probably"___"．
A．节能
B．仪器
C．实验
D．开关
35．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．

32．A 细节题．根据第四段第二句 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 the computers 可知，他解释说这些能量被使用了两次-一次用来加热房间，一次用来冷却电脑，并且用户不用花钱来冷却电脑．由此可知，它主要用来供热．B项意为"用来驱动电脑"，D项意为"用来帮助微软"，C项意为"用来加热电脑"，均不符合题意．故正确答案为A．
33．D 细节题．根据第二段最后一句 These systems send the heat into the air 可知，这些系统将热量释放到空气中．D项意为"释放到空气中"，符合题意．B项意为"帮助五个房主"，C项意为"被使用两次"，A项意为"使电脑更好地工作"，均不符合题意．故正确答案为D．
34．B 猜测词句题．根据上下文可推知，the e-Radiator，即电子散热器是一种仪器、装置．device 指代 the e-Radiator，故可推测其意思为"仪器"．
故正确答案为B．
35．C 主旨题．根据上下文可知，本文主要介绍了一种新的供暖设备 the e-Radiator，即电子散热器，且由第四段第二句 once to heat the home and once to cool the computer and that the users don't have to pay to cool the computers 可知，这些能量一次用来加热房间，一次用来冷却电脑，并且用户不用花钱来冷却电脑．由此可推知，文章围绕这种新的供暖方式来进行叙述．C项意为"一种新的供暖方式"，符合题意．A项意为"一个环境问题"，文章没有提及．B项意为"未来的电脑"，文章只是通过电脑所产生的热量而引出供暖方式．D项意为"被浪费的能量"，文章提到了电脑所产生的热量被浪费掉，但是并没有就此展开，而是引出了新话题 e-Radiator．均不符合题意．故正确答案为C．
