Powered by Microwaves

(微波动力飞机)

Canadian Scientists have successfully tested an unusual airplane. The airplane is not powered by fuels. It is powered by microwaves. Microwaves can be produced by equipment on earth. When the microwaves hit the bottom of the plane’s wings, instruments’ change them into a more usable form of energy—electricity. The electricity powers the plane’s engine.

　　  The plane was developed by the Canadian government and the University of Toronto. The plane is called the Sharpfire. The Sharpfire is much too small to carry people or equipment. It was built only to see if the technology would work. Sharpfire is made of light weight wood．Its wings are about three and one half meters across. In its first public test, the Sharpfire flew eighty meters above the ground for almost four minutes. A future microwave plane will be much larger than the Sharpfire. The main reason for using microwave energy to power an airplane is to end the plane’s need to carry fuel. An American researcher says this technology will be very common in the next century.

    Then why am I able to write about computers? I can write on this subject because of these shortcomings. The last two years of learning have been a hard test for me. By hard work I have managed to learn enough to use computers fairly well, and to work with people who know a great deal more than I. Since I have learned all this at such personal cost, I would like to share my knowledge with others. More and more people want to know about computers, and want to know quickly.

    The best way to learn is to take a course. However, many people do not have the time for this. They will have to find some other way to get some basic information. I hope to be able to help them by writing about some of the things I have learned myself.

    I have a home computer on which I’ve learned in my own time. I have used it like a home study course. I have sat down with it day after day, night after night. I have forced it to give up some of its secrets. Now I can use it to do some of the work that I get paid for. And I can do this work in my own home, instead of in an office. Many people may soon be working in a computer at home, just as many now take in other people’s typing.

    Some things about computers are easier than you may fear. First computers are logical. Things that at first seem difficult will make sense to you after you learn the rules. Second, it is really not hard to learn enough to use today’s machines. You do not need to be a great brain. But you do have to learn to think in new ways. And you do have to keep a good bit of information in your head. Finally, there are many people around who are really enthusiastic (热心的) about computer. These people are always happy to be of help.

    Are American youngsters as physically fit as the Russian youngsters? No, says the President’s council(委员会) on Physical Fitness and Sports.
