问题     Should we invest money in space research?
选项
答案 For over fifty years, a number of nations have been involved in the exploration of outer space. This research has been very costly. Has this money been well-spent or wasted? Some people believe that the research should be eliminated because of its expense, not only in terms of money, but also in terms of the scientific and human resources. These people point out the fact that it cost billions of dollars to send astronauts to the moon, but they just brought back worthless rocks. These people say that the money and effort could be spent on more important projects right here on Earth, such as providing housing for homeless people, improving the education system, saving the environment, and finding cures for diseases. However, other people believe that space research has provided many benefits. They point out that hundreds of useful products, from personal computers to heart pacemakers to freeze-dried foods, are the direct or indirect results of space research. They say that weather and communication satellites are also products ot space programs. In addition, supporters of the space programme point to the scientific knowledge that has been acquired about the Sun, the Moon, the planets, and even our own Earth as a result of space research. I agree with those people who support space research. Space research has already brought many benefits to humanity. Perhaps it will bring even more unimaginable benefits in the future. Moreover, just as individual people need challenges to make their lives more interesting, I believe the human race itself needs a challenge, and I think that the peaceful exploration of outer space provides just such a challenge.
