Sample 1:Recently, students in our class have had a discussion on whether space is worth exploring. On the one hand,30% of us think that space exploration is not worthwhile. They think space is too far away from us and our daily life. And space exploration will waste a lot of money, which can be used to solve the problems such as starvation and pollution. On the other hand, 70% think space is worthy to be explored . As we all know, satellites have been used for communication as well as weather forecast, which make our lives more convenient. Besides, if resources are found on other planets, the problem of energy shortages on our earth can be solved.
