Every human being, no matter what he is doing, gives off body heat. The usual problem is how to dispose 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 utilizes not only body heat, but the heat given off by such objects as light bubs and refrigerators as well. The system works so well that no conventional fuel is needed to make the campus’s six buildings comfortable.

Some parts of most modern buildings—theaters and offices as well as classrooms are more than amply heated by people and lights and sometimes must be air-conditioned even in winter. 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 re-use it in others.

Along the way, pit has learned a great deal about some of its heat producers. The harder a student studies, the more heat his body gives off. (76) Male students emit more heat than female students, and the larger a student, the more heat he produces. It is tempting to conclude that the hottest prospect for the Johnstown campus would be a hardworking, overweight male genius.

1.C 答案是開頭的第二句：The usual problem is how to dispose of it。Dispose of “處理解決”。

2.B 答案在第一段的第三句中。他們設計了一種收集系統(tǒng)，它不但利用身體的熱，還收集由燈泡、冰箱等散發(fā)出來的熱。有了這兩種熱能，作者指出在校園中已無需任何conventional fuel

3.C 第二段中說：大多數現代化的大樓有些部分—戲院、辦公室以及教室是用人體和燈光的熱來供熱的，有時候甚至在冬天的空調也是由它們來供熱。Even意為“甚至”。

4.D 回收再利用熱能。此題考察學生對全文的總結能力，以及reclaim和re-use的詞義。

5.B 最后一段倒數第二句說：男學生發(fā)出的熱量比女生發(fā)出的熱量多，學生體重越重產生的熱量越多。學習刻苦的比學習不刻苦的產生的熱量多。所以最瘦的女生產生的熱量最少。

A fire drill is，to put it mildly，an inconvenient exercise at the best of times. A fire drill at 2：00 in the morning in terrible weather conditions，like the one we had on Thursday night and Friday morning last，is incomparably more inconvenient. This is why writing this note to thank you all most sincerely for your excellent co-operation and the spirit with which you endured the inconvenience.

A fire drill is not an idle exercise. It is an extremely serious one and can，in fact，save lives in the long run. Last week fire drill has already reyealed a number of important things regarding fire precautions in the Hall. For instance， there seem to exit a number of “deaf spots” in the Hall，namely，the two rooms in Purser House and some rooms in the Bottom corridor. I have no reason to doubt that residents from these areas could not hear the alarm. I shall request an immediate examination of this problem.

I should，also，remind you that it is a requirement that fire drills should be regularly carried out (at least two in every one year)and each resident should be made fully aware of this and obliged to take part. All residents must take fire precautions with the seriousness they deserve. Failure to do so can result bin fines and expulsion(驅逐)from the Hall. Thank you again for your co-operation.
