Some scientists believe that intelligent life forms may exist on other planets and some want to send message to contact them. Others think it is a bad idea because these life forms may be too dangerous. Discuss both views and give your own opinion. 20161013

　　10月13日雅思A类大作文考了一个科技相关的题目，在审题之后，都会发现这的确是一个和太空技术有关的题目。题目讨论的关键也的确是人类是否应该和可能存在的外星人联系。这类文章的确可以放开脑洞，天马行空进行想象，写成作文的时候，会发现下笔的确的有些崩溃。来看看环球教育名师杨亮老师的观点吧。

　　Scientists in some space research institutes have been sending message to some corners of the universe since they were able to do that. Possible consequences of doing so, seemingly, have not been carefully analyzed yet.

　　本段的开头算是言简意赅了。其实，众所周知往外太空发信号，绝对不是一天两天的事情了。咱们国家刚刚建成的那个“大锅盖”可不是为了看电视多收几个频道。因此一个简单的背景介绍之后，就是明确地表达了笔者的观点。对此，笔者表示并不乐观。毕竟笔者是看了很多科幻片的。

　　Primarily, building connection with other intelligent species with humans' current technology does require incredibly high cost. This is to say, tremendous fund ought to be utilized for related technology research and establishment of some certain facilities instead of being used for solving some livelihood problems. Even though mankind were setting up connection with aliens who are living in a couple of light years away and are obviously less civilized with less advanced technology, with limited space technology that humans have currently we would be able do nothing further. Investing billions of dollars for saying hi to someone who might not understand at all is definitely not a wise decision.

　　坦言之，在写这道题之前，笔者还真心的思考过这么问题。那是午夜梦回，辗转难眠的夜晚。笔者仰望星空，发现，其实也看不到啥。但是这并不影响笔者对于这个关乎全人类未来的命题的思考。以人类目前的有限的太空技术，和外星人建立联系肯定是大费周章的事情。那么如果被我们联系到的外星人文明程度还不如我们。那将是一个极其尴尬并且非常不经济的局面。耗费大量人力物力只为了和外星人打个招呼，并且对方还不一定能懂。这明显不是一个明智的决定。简言之，这段针对题干当中第一部分的人的观点进行论述。只论证，如果外星生物的智能程度不如我们的情况。为下文留下伏笔。

　　Worse, unknown creatures that receive humans' greeting are more advanced and intelligent ones than inhabitants of the earth. What will happen at that time is more likely to be what people often see in science fiction movies nowadays. "White house is being attacked and Air Force One is shot down by missiles from unidentified flying objects". Intelligent species are not willing to co-exist peacefully or harmoniously with other creatures whose civilization apparently lags way behind. Their greed drives them use wars to make the earth their colony offering whatever they need from this planet. If that happened, humans would extinct and the only survivors would live their life in zoos of aliens.  

　　承接上文，如果被我们联系到的外星生物在文明程度和科技发展领域都完胜地球上这些愚蠢的人类。那么后果不堪设想，在这里请大家自觉脑补各种科幻片里面的破坏场面。请大家放心，首先被袭击的永远是纽约，美国都快被消灭完了，外星人才会发现，原来地球上还有个亚洲。总之，这段直接回答了题干中另外一部分人的观点，并且肯定了他们的想法。

　　As has been mentioned above, possible outcomes of sending message to unknown life in somewhere of the universe are what humans cannot afford or what we cannot accept. Therefore, space telescopes are not what we should spend money on, as paying for risks is never worthy.

　　结尾简要地表达笔者观点。与外星人建立联系，不是徒劳无功就是引狼入室。
