Recently, students in our class have had a discussion on whether space is worth exploring.30% of us think space exploration is not worthwhile. They think space istoo far away from us and our daily life. And the money spent on space exploration ca n be used to solve the earth’s problems such as starvation and pollution.On the other hand, 70% think space is worth exploring because we have benefited a lot from it, such as using satellites for communication andweather forecast. What’s more, with further space research, we may solve the population problem by moving to other planets one day. Also, space researchwill enable us to find new sources to solve the problem of energy shortages on the earth.翻译：最近，我们班的学生们就太空是否值得探索进行了讨论。
