(1.)Every human being, no matter what he is doing, gives off body heat. The usual problem is how to dispo of it. But the designers of the Johnstown campus of the University of Pittsburgh t themlves 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-u it in others.
开放式问题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 f
emale 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.

(2.)America is in no immediate danger of “running out of water”. People in the Wes
t have been 世博演艺中心aware that water is a precious commodity and must be conrved. In the damp East, an excess of water led to complacency until two factors created concern over our water supply. First, the periods of drought from the 1961 to 1966 in the Northeast affected crop production and ud up the surface and ground water supplies. Second, attention was called to rapid increas in the rates of pollution of the waters resulting from incread urban and industrial growth. As a result, there is an increasing awareness of the need for conrving the quantity and quality of our nation’s water supplies.
Water is a renewable resource, but it is not exhaustible. When ud for municipal, industrial, or agricultural purpos, it is not destroyed, but generally finds its way back into our water supply. This ud water now carries some waste materials. The dirty waters are often dumped into large bodies of water or are dispod of on land. In the latter instance, evaporation concentrates some of the wastes on the soil surface. On the other hand, water moving through the soil will eventually carry some of the wastes down into the ground water supplies, Eventually, all water evaporates and later returns to the earth as rain or snow in a relatively purer state.
Through this never-ending cycle, there is just as much water in this country now as there ever was. The amount, however, does not increa. Our rapid population growth and our agricultural and industrial expansion have caud our water needs to soar. By withdrawing water from streams too quickly, we have in some instances upt the balance of nature’s built-in renewal process for conrving water. As a result, some of our streams and lakes have become “wet derts.” There is still plenty of water in them, but its water is so polluted that it supports almost no life at all.
