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 bulbs 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 reuse 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 more heat than female students, and the larger a student, the more heat the produces. It is tempting to conclude that the hottest prospect for the Johnstown campus would be a hardworking, overweight male genius.
The phrase “heat recovery” refers to a____.( )

由文章开头的第二句“The usual problem is how to dispose of it”可知C项正确。
I worked for a short time as a cashier at a restaurant a few months ago. I also helped to clean up the tables when it was very busy. One night, just before Christmas, I found a large black wallet on the floor near one of the tables. I guessed I should check it to find out who was the owner, but I was very busy at the time. And I imagined that if there was something valuable in the wallet, the owner would be back. Sure enough, an hour later a man came up to the counter and asked if anyone had found a wallet. l asked him to describe the lost wallet, and after he described it exactly, I gave him the wallet. He expressed his thanks when I handed it to him. He asked me if I had opened it, and when I told him “no”. At once he opened it and showed that it had nearly $800 in cash. He took out a twenty-dollar bill and handed it to me and I was amazed at this. “A reward for your honesty,” he said and then turned and walked away.
Thinking about it later, I began wondering whether I would have been honest if had known what was in the wallet! I thought that if I had no way to find the owner and no one returned to get it, I might keep it. But it also came into my mind that I actually saved someone's Christmas plans by finding and returning the wallet. The good feeling it gave me was worth more than anything could buy.
Which of the following is NOT true?( )

由于作者并未打开钱包,更没有从中取出什么,所以说“Nothing in the wallet was missing”。
Interact 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 Internet 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 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.”
