Question

Every human being, no matter what he is doing, gives off body heat. The usual problem is how to get rid of it. But the designers of the Johnstown campus (校园) of the University of Pittsburgh set themselves the opposite problem — how to collect body heat. They have designed a collection system which uses not only body heat, but the heat given off by such objects as light bulbs and refrigerators as well. The system works so well that no fuel is needed to make the campus’s six buildings comfortable.

Some parts of most modem buildings — theaters and offices as well as classrooms, are more sufficiently heated by people and lights and sometimes must be air-conditioned (使用空调的) even in winter. The technique of saving heat and redistributing (再分配) it is called “heat recovery”. A few modern buildings recover heat, but the University’s system is the first to recover heat from buildings and reuse it in others.

Along the way, Pittsburgh has learned a great deal about some of its producers. The harder a student studies, the more heat his body gives off. Male students send out more heat than female students, and the larger a student is, the more heat he produces. We may conclude that the hottest prospect for the Johnstown campus would be a hard working overweight mate genius.

1.The heat in the heating system of the Johnstown campus is supplied ________.

A. by human bodies

B. by both human bodies and other heat-giving objects

C. by both human bodies and commonly used fuel

D. by human bodies, commonly used fuel and other heat-giving objects

2.According to the passage, the technique of heat recovery is used ________.

A. to find the producers of heat

B. to provide heat for the hot water system

C. to make the campus more beautiful

D. to collect heat and reuse it

3.The underlined phrase “the hottest prospect” in this passage refers to ________.

A. the person who suffers most from heat

B. the person who needs more heat than others

C. the person who gives off most heat

D. the person who makes better use of heat

4.Which of the following may be the best title for this passage?

A. A New Heat Recovery System in Pitt

B. Modern Building’s Heat System

C. Body Heat and Its Producers

D. Ways of Heating Building

Answer

1.B

2.D

3.C

4.A

【解析】本文是一篇说明文。主要介绍了Pittsburgh大学通过收集人体以及其他物体释放出的热量，并将收集到的热量进行再分配来对建筑进行供暖的技术。

1.细节理解题。根据第一段They have designed a collection system which uses not only body heat, but the heat given off by such objects as light bulbs and refrigerators as well.可知，这种收集系统不仅使用人体的热量，还使用由像灯泡和冰箱这种物体释放出的热量。故选B。

2.细节理解题。根据第二段The technique of saving heat and redistributing (再分配) it is called “heat recovery”可知，“热回收”这种技术是储存热量，然后在重新分配热量。故选D。

3.词义猜测题。根据最后一段We may conclude that the hottest prospect for the Johnstown campus would be a hard working overweight mate genius.可知，前文对释放热量多的特征进行了说明，所以我们可下结论，Johnstown校园的the hottest prospect将是个勤奋学习、身材臃肿的男性天才，由此可知the hottest prospect的意思是“释放最多热量的人”。故选C。

4.主旨大意题。根据全文可知，通篇文章都是在介绍Pittsburgh大学的一种“热回收”系统，这种系统可以收集人体以及其他物体释放出的热量，然后将这种热量重新分配用于建筑的供暖。A项“Pittsburgh大学的新型热回收系统”最适合作文章题目。故选A。
