Is Space Research a Waste of Money?
提纲
1．有些人认为探索太空的花费是一种浪费。
2．有些人则不这样认为。
3．我支持太空研究。
    For over fifty years, a number of nations have been involved in the exploration of outer space. This research has been very costly, of course. Is this money well-spent or wasted?
    Some people believe that all or most space researches should be stopped because of its incredible expense, not only in terms of money, but also in terms of scientific and humaa resources. Those people point ont the fact that it cost billions of dollars to send astronauts to the moon, but all they brought back were some worthless rocks. However, other people believe that space research has provided many benefits for mankind. They point oat that hundreds of useful products, from personal computers to heart pacemakers to freeze-dried foods, are the direct or indirect results of space research.
    I agree with those people who support space research and want it to continue. Space research, as shown, has already brought many benefits to humanity. Perhaps it will bring even more benefits in the fatare, ones that we can not even imagine now.
