雅思写作
一些科学家认为，智能生命形式是有可能在其它星球上的，并且有一部分人想要把我们的信息传递给他们，在上世纪80年的时候，已经达成共识不再对外太空传递我们地球的信息，针对这种操作，有些人认为这是一个坏主意，因为或者其他生命形式太危险。讨论两种观点并给出你的意见。
Some scientists believe that intelligent life forms may exist on other planets and some want to send messages to contact them. Others think it is a bad idea because these life forms may be too dangerous. Discuss both views and give your opinion.
段落1: 转述题目，提出两种观点。
For decades scientists have searched for proof of intelligent life forms on other planets. Some believe that we should try to contact them, whereas others believe it is too risky. This essay will discuss both views and offer my own opinion.
段落2：对于正反双方的观点分别论述
正方：外星有先进的科技----解决地球上的现存问题；人类在太空生存
反方：外星生物可能对人类造成伤害----先进的武器；与人类无法交流沟通
Scientists have warned for many years that at some point Earth will become uninhabitable. Many believe intelligent life forms would have technology far beyond our human capabilities, which could offer us solutions to many of the issues we face today, such as global warming, over-population and dwindling natural resources. Furthermore, their technology may even show how life on other planets could be viable. Conversely, it is this same knowledge that could prove harmful to humans. Intelligent life forms could use their technology as weaponry against humans. Moreover, it is also important to acknowledge that we most likely would not share a common language, which could lead to catastrophic misunderstandings.
段落 3：自己的观点
更认同反方观点----强调联系外星人可能带来的风险----传染病，破坏地球等
In my opinion, though it is exciting to consider the existence of intelligent life forms elsewhere, it is more pertinent to consider the risks of such a venture. The human body is vulnerable, and contact with aliens could open us up to disease and infection that we do not have the capabilities to cure. Moreover, though humans may have good intentions, the civilisations we contact may not necessarily have our best interests in mind. We should bear in mind our own history of colonisation, and consider that it may be that we ourselves could be colonised or destroyed by aliens. Lastly, even if intelligent bodies do exist elsewhere, they may not wish to be contacted by humans.
段落 4： 结论
寻找外星人的研究要以人类的安全为基础
To discover life elsewhere would be a giant step in scientific advancement, but we need to consider whether it is the safest choice we can make.
