Every human being, no matter what he is doing, gives off body heat. The usual problem is how to dispose(处理) 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 bulbs(灯泡) and refrigerators as well. The system works so well that no conventional(常规的) 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. Male students emit(发出) 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(天才). Which of the following is true of the heating system of the Johnstown campus

Internet use appears to cause a drop in psychological health, according to research at Carnegie Mellon University.Even people who spent just a few hours a week on the Internet experienced more bad feelings and loneliness than those who was online less frequently, the two-year study showed. Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.The fact that Internet use reduces time available for family and friends may account for the drop in psychological health, researchers hypothesized (推测). Faceless, bodiless "virtual"(虚的) communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that exposure(暴露) to the wider world through the Net makes users less satisfied with their lives."But it" s important to remember this is not about the technology, it" s about how it is used," says psychologist Christine Riley of Intel, one of the study" s sponsors (发起人). "It really points to the need for considering social factors in terms of how you design applications and services for technology."
