Outer Space Explorations，YES or NO
We had an argument over whether it is necessary to carry out outer space explorations at a class meeting the other day. Different students have different attitudes towards it.
Some of us think it’s important to research the outer space. First of all，people can get a better understanding of the outer space through their exploration. Secondly, new resources can be found there for human being. Thirdly, this exploration can possibly bring about new living space for human life in the near future. However, others are strongly against it.They believe that it takes so much money to do this kind of exploration, which is not worth the value. Besides, it is very dangerous for astronauts to do such work in the outer space.
In my opinion, people should be pioneering, and therefore such explorations into the outer space are worth trying out.
