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 (校園) 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 modern buildings — theaters and offices as well as classrooms, are more sufficiently heated by people and lights and sometimes must be air-conditioned (使用空調(diào)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 male genius.

Ways to save time

We all wish we had just a bit more time. Just think what you could do with an extra hour or two each day: you could finally stick to an exercise routine, or spring-clean the house, or write your novel, or learn the guitar and so on.

1.But I can help you find more hours in your day for the things that really matter.

★Get Out of Bed Earlier.

If you normally get up at 7:30 a.m. try getting up at 7:00 a.m. That half-hour might not sound like much, but it could be time that you use to exercise, to read that book you've been meaning to finish.2.

★Do the Important Tasks First.

Once you get to work, get the important ones done first (not the easy ones, or even the urgent ones). 3.If you work like this, you’ll usually save time. The urgent tasks will still get done, and you won't miss the important ones.

★Reduce Interruptions.

If colleagues have a habit of hanging around your desk to chat, or if the phone is constantly ringing, you might find that it takes you half the day to finish a simple task like writing a letter.4.

★5.

A few minutes chatting, browsing the web, and so on, can easily turn into hours of wasted time over the course of a day. If your concentration is slipping, take a proper break: go and get a glass of water, or stretch your legs a bit. And if you’re facing a difficult task, try breaking it into small steps or stages so that it’s easier to deal with.

A. Stay Focused on Your Work.

B. Take Breaks When Necessary.

C. Would you want me to make your day longer?

D. I can’t magically make all your days 25 hours long.

E. Or simply to get your day off to a calm and organized start.

F. Constant interruptions don’t just eat up time, they also break your concentration.

G. You can afford to spend at least an hour working on big, important tasks rather than on all those little urgent ones.
