Traveling to the outer space has brought to such popular attention that a large number of countries place it on the agenda as an important matter. Some people believe that space exploration could not bring many changes to people’s life. However, I disagree with it to some extent.It is admittedly true(意思重复) that the changes that space travel brings may not be so obvious that anyone in the world could reap many benefits. Most of results, as every outsider saw, are just some rocks and sand from the moon. Even, some opponents of the space travel point outthe fact that there are an increasing number of matters confronted by(好像没有这种用法,我的建议是改成——people are confronted with an …) people, which should be considered first. The money and efforts now being wasted on space travel could be wisely spent on other more essential matters, such as environmental protection, solving the problems of housing shortage.However, the benefits that space exploration brings should not be overlooked. A large number of great inventions, some of which even play significant parts in saving people’s lives, are the direct or indirect results of space exploration. For instance, neither heart pacemaker nor freeze-dried foods could be invented without space program. Furthermore, the exploration of the outer space is an essential way for people on earth to find another planet for them to live, for the environment on earth has been destroyed to such a serious extent that human beings may be unable to rely on. Lastly, the supporters of the space programs point to the scientific knowledge that could be obtained from the outside world.In conclusion, the space research could bring enormous positive changes not only on practical benefits but also on theoretical knowledge. Therefore, space travel is of great necessity to people living on the earth. 嘻嘻!进步挺大的~~ |
