More Exercise
1. Physical fitness is the result of many factors－good medical and dental care, proper nutrition, adequate rest and relaxation, and sensible personal habits. But these are never enough. An essential factor is regular physical activity－exercise for a body that needs it to function well.
2. All of us know that ordinary movements－things like running, jumping, and bending－are made by muscles. Muscles also do many other things. They suck air into your lungs, push food along your digestive tract, and tighten your blood vessels to raise blood pressure when you need more pressure for an emergency. Your heart is a muscular pump.
3. When your muscles are not used, or are not used enough, they do not develop and grow properly. They soon become flabby and weak, shrink in size, and lose the ability to do the jobs they were meant to do.
4. Recent studies showed that the average high school student spends fifteen to thirty hours a week watching television and only two hours a week in organized play or exercise. That is one reason why one-third of the 200,000 pupils tested for the Presidents Council on Physical Fitness failed a simple test of strength, stamina, and flexibility. Some of the boys and girls could not raise themselves to a sitting position without using their hands!
5. Cars and buses, elevators and escalators, TV and push-button machines all tend to reduce strenuous physical activity. But our bodies still need exercise. Without it they soon become weak, ineffective, and unattractive.

Computer
There is no denying that students should learn something about how computers work, just as we expect them at least to understand that the internal combustion engine （内燃机） has something to do with burning fuel, expanding gases and pistons （活塞） being driven. For people should have some basic idea of how the things that they use do what they do. Further, students might be helped by a course that considers the computers impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy （读写能力）; it is a trade skill that should not be taught as a liberal art.
Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers. But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun, and while our society needs some people who are experts at it, the same is true of auto repair and violin-making.
Learning how to use a computer is not that difficult, and it gets easier all the time as programs become more "user-friendly". Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen. What does the phrase "learning to use a computer" mean? It sounds like "learning to drive a car", that is, it sounds as if there is some set of definite skills that, once acquired, enable one to use a computer.
In fact, "learning to use a computer" is much more like "learning to play a game", but learning the rules of one game may not help you play a second game, whose roles may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program and generally that is easily accomplished.
