写作思路：可以从人类为什么探索太空这个角度出发进行阐述，中心要明，语言要通顺等等，比喻语法使用错误。

正文：The purpose of human development of science and technology is to obtain more power and resources from nature. Improve their living conditions.人类发展科技的目的是什么，就是为了从自然界获取更大的力量，更多的资源。

改善自己的生存条件。

After all, the earth is only that big. The development direction of human technology must be the universe. We need to fly farther and faster to other planets and the universe. This is our direction and our goal.地球毕竟只有那么大，人类的技术发展方向必然是宇宙，我们需要飞得更远，更快，到其他星球上去，到宇宙中去。

这是我们的方向，是我们的目的。

As for the fact that the development of aerospace technology can drive the development of other technologies, for example, Apollo program has brought us a non stick pot, which is only incidental, not the main purpose and motivation of aerospace development.至于说，宇航技术的发展可以带动其他技术的发展，比如说阿波罗计划为我们带来了不粘锅，那只是附带的，不是宇航发展的主要目的和动机。
