Unit 4 Astronomy: The science of the stars 范文赏析与背诵 你班就“是否应该花费巨大的人力、物力和财力进行太空探索”进行了讨论。 有些人认为太空探索完全是浪费时间和金钱。理由是收效甚微、花费巨大。 但大多数同学认为进行太空探索利大于弊，许多新产品，如气象、通讯卫星都直接得益于太空研究，使全球受益匪浅。 你的观点------ Do we need space exploration? Man has been fascinated by outer space for thousands of years. It has been over forty years since man’s first landing on the room. Now some people believe that space exploration is a waste of time and money. They point out the fact that it cost billions of dollars to carry on the space research, but a little information has brought back. However, every coin has two sides. There are still a majority of other people who believe that space exploration has more disadvantages. And I agree with those people. Many new products, such as weather and communication satellites, are also products of space programs, and the have benefited people all over the world. And what’s more, scientific knowledge about outer space has been acquired by mankind. We believed that it will bring more benefits in the future, which we cannot even imagine now. Space exploration is challenge o human beings. That’s why several nations try hard to carry out space exploration continuously. |
