【题目要求】

最近，你班同学就“太空探索是否值得”这一话题展开了一场讨论。请你根据下列提供的信息，用英语写一篇短文介绍讨论的情况。
30%的同学认为太空探索不值得，70%的同学认为值得探索。

Sample Writing
Recently, students in our class have had a discussion on whether space is worth exploring.
30% of us thinkspace exploration is not worthwhile. They think space is too far away from us and our daily life. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.
On the other hand, 70% thinkspace is worth exploring because we have benefited a lot from it, such as using satellites for communication and weather forecast. What’s more, with further space research, we may solve the population problem by moving to other planets one day. Also, space research will enable us to find new sources to solve the problem of energy shortages on the earth..

Sample Writing
Space Exploration is a Waste of Time and Money
Everyone gets excited by the news of the most recent space flightsand I too share in people's sense of awe and wonder at the photos from space that we see. Having said that, it is hard to believe that the high cost of space flight is justified so that we can get some lovely pictures. We should be spending our money more wisely, on what people need.
I cannot understand spending all this money on expensive research and experiments when so many people need food.Around the world, millions of people are hungry and dying of starvation.On the other hand we hear on TV that for as little as a dollar a day a child in Africa can be saved.Considering the billions spent on space travelit just seems a better investment to feed the hungry.
Some people argue that someday we will have to go live in space because the world will be made impossible to live in through pollution.This seems silly.When your house gets dirty, you spend the time and money to clean it up.You don’t move house simply because you need to wash your windows or vacuum the floor.In the same way, it makes more sense to use our time and money to take care of our planet, rather than look for a new home.
Finally, there are a lot of unsolved mysteries on the earth. So why are we going into space to explore? There are still many things to discover in the ocean depths and the Antarctic. But we do not even have to go that far: Science has yet to unlock all the mysteries of the atom, and there are many realms of technology that we are just beginning to understand and explore.
In the end, it just does not seem a very wise investment to go to space.We have too many needs here on the earth to be wasting our effort on space exploration.
