关于太空探险的意义的英语作文``

Dear Editor,
　　We had a discussion over whether it’s necessary to carry out the
outer space explorations at a class meeting the other day. Some of us
think it important to research the outer space. First, people can get a
better understanding of the outer space through their explorations.
Second, new resources can be found there for humans to use. Third,
explorations can possibly bring about new living space for human life.

　　However, others don’t believe so. They say this kind of exploration
costs too much money. And it’s very dangerous for astronauts to do such
work.

　　I think people should do the explorations and therefore such explorations into the outer space are worth trying out.

　　Yours,
　　Zhou Yong
