Every human being, no matter what he is doing, gives offbody heat. The usual problem is how to get rid of it. But the designers of the Johnstown campus of the University of Pittsburgh set themselves the opposite problem — how to collect body heat. They have designed a collection system which[22]utilises not only body heat, but the heat given off by such objects as light bulbs and ice-boxes as well.[23]The system works so well that no general fuel is needed to make the campus’ six buildings comfortable.     Some parts of most modern buildings — theatres and offices as well as classrooms — are more than enough heated by people and lights and sometimes must be air-conditioned even in winter.[24]The technique of saving heat and redistributing it is called "heat recovery". A few modern buildings recover heat, but the University’s system is the first to recover heat from some buildings and reuse it in others.
    Along the way, Pitt has learned a great deal about some of its heat producers.[25]The harder a student studies, the more heat his body gives off. Male students emit more heat than female students, and the larger a student, the more heat he produces. It is concluded that the hottest prospect for the Johnstown campus would be a hard-working, overweight male genius.
22. What do we know about the heat collection system?
23. How many buildings are heated entirely by the heat collection system on Johnstown campus?
24. What does heat recovery refer to, according to the passage?
25. Which of the following kinds of people would produce the least amount of heat?

选项 A、One.
B、Two.
C、Four.
D、Six.

答案 D

解析 细节题。文中明确提到The system(heat collection system)很好用,所以no general fuel is needed(不需要其他燃料)就可以make six buildingscomfortable,由此可知有六座建筑完全用这种集热装置供热,故答案为D)。
