Every human being, no matter what he is doing, gives off body heat. The usual prob-lem 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 de-signed a collection system which utilizes not only body heat, but also the heat given off by such objects as light bulbs and refrigerators as well. The system works so well that no con-ventional fuel is needed to make the campus’s six buildings comfortable.
Some parts of most modern buildings-theaters and offices as well as classrooms-aremore 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, Pitt has learned a great deal about some of its heat producers. The harder a student studies, the more heat his body gives off.
Male students emit more heat than female students do, and the larger a student is, the more heat he produces.
It is tempting to conclude that the hottest prospect for the Johnstown campus would be a hard-working, overweight male genius.
Which of the following is true of the heating system of the Johnstown campus?
选项
A、The heat is supplied by human bodies only.
B、The heat is supplied by both human bodies and other heat-emitting objects.
C、The heat is supplied by both human bodies and conventional fuel.
D、The heat is supplied by human bodies, other heat-emitting objects, and con-ventional fuel.
答案
B
解析
答案在第一段的第四和第五句中。他们设计了一种收集系统,它不但利用人体的热,还收集由灯泡、冰箱等散发出来的热。有了这两种热能,作者指出在校园中已无需任何conventional fuel。
