关于探索太空的英语作文

Man has been fascinated by outer space for thousands of years. It has been
almost over forty years since mans first landing on the moon. Now, some people
believe that space exploration is a sheer waste of time and money. They point
out the fact that it cost billions of dollars to carry on the space research,
but a little information was brought back.
　　 However, every coin has two
sides. There are still a majority of other people who believe that space
exploration has more advantages. And I agree with those people. Many new
products, such as weather and communication satellites, are also products of
space programs, and they have benefited people all over the world. And whats
more, scientific knowledge about outer space has been acquired by mankind.
We believed that it wi!/bring more benefits in the future, which we can not
even imagine now. Space exploration is a challenge to human beings. Thats why
several nations try hard to carry out space exploration continuously.（英语作文）
　　翻译：
　　 我们是否需要太空探索
人类对外部空间着迷已有上千年的历史了。从人类第一次登上月球起至今已有四十多年了。现在，有些人认为空间探索完全是浪费时间和金钱。他们指出，数百亿美元用于太空研究，但收获甚微。

然而，任何事物都具有两面性。仍有大多数人认为进行空间探索利大于弊，我也非常赞同他们的观点。许多新产品，如气象、通讯卫星都直接得益于空间研究，使全球受益匪浅，而且人类从中获得了不少关于太空的知识。
我们相信，将来它会带给人类更多的好处，有些甚至是我们现在无法想象的。太空探索对我们人类来说是个挑战，这也是为什么许多国家不断进行探索的原因之一。
