雅思大作文高分范文——科技类

题目

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

范文

　　The issue of whether human beings should look for and make contact with intelligent life forms in outer space has caused heated debate. From my point of view, I believe that by making contact, this may bring about the destruction of Earth

　　With the development of current space technology there have always been experts in the field that have encouraged making contact. They believe that with the evel of modem technologies, such as space travel and astronomic observation, we are ready to make contact with life forms from other planets. This fact, that we are rapidly technologically advancing, pushes us closer to wanting to make the step to establishing a relationship with aliens. Also, some scholars claim that at the rate humans take from the Earth, very soon we will run out of the natural resources we need to survive. By further exploring outer space and making contact with aliens, we can significantly improve our technology for nterplanetary travel and altemative energy resources

　　However, humans looking for life on other planets seems to be an unwise move for the Earth. Firstly, the environmental conditions on other planets can be a problem for humans, but also they may be scientifically and technologically advanced far beyond what we are able to imagine. Then if, for example, they found something which was plentiful on our planet and of great value to them, but they lacked on theirs, it may be quite possible that star wars would go from science fiction to reality. Furthermore their cutting-edge technology and weaponry may put us at a disadvantage. We only need to look at our own history to see that the first contact with other civilisations was not always friendly meeting

　　Overall, human beings intentions towards aliens are cordial and friendly, but this does not mean they would respond with the same feeling. Considering, the current circumstances of our cognitive level of sclence, we should not attempt to make contact with aliens in the best interest of our own planet.

　　究竟人类是否应当主动寻找并联系外太空中的其他智能生命的话题在社会上引起了热烈的讨论。就我来说，我认为这样做可能会带来地球的毁灭。

　　随着当今空间技术的发展，总有些专家提议联系外星人。他们认为现代技术的发展水平已经非常先进了，如字航技术和天体观测技术，我们有把握和外星智能生命进行正面接触。我们的技术突飞猛进这个事实进一步推动了与外星人建立联系的想法。此外，也有一些学者认为考虑到目前的消耗速度，在不远的将来我们赖以生存的资源也终将面临枯竭。通过进一步寻找外太空的生命井与之联系，我们才可以更好地发展空技术用于星际穿越或者可替代能源等目的。

　　但是，寻找外太空智能生命对地球来说不能说是一个明智的举动。首先，不仅外星人所生活的环境对我们来说可能会是一个问题，而且他们所掌握的科技可能是超越人类认知的。比如，有可能在某些星球极其缺乏的某种元素或者材料在地球上却很丰富，那么科幻小说中的星球大战将极有可能变为事实。此外，对方的尖端科技和武器也可能使我们处于劣势。我们只需要看一下历史就会明白，与其他文明的首次接触并不都是非常友好的。

　　综上所述，来自人类的邀请是非常友善的，但这不一定就意味着外星人的回应也是友善的。以目前地球的科学认知水平来看，为了地球的最佳利益，我们不应该试图联系外星人。

环球名师点评

　　第一次看到这道题的时候，我脑子里在想:这道题会把多少考生“逼上绝路”啊!

　　首先，不同于普通的科技类话题，外星人话题太边缘化了很多考生用中文可能都写不出来几个句子。

　　其次，这种话题涉及社会发展、人类文明甚至是非常抽象的道德伦理，对于大多数考生来说，都会觉得比较难把握。

　　最后，这种边缘话题最大的难点就是不熟悉相关词汇想到“星际穿越”“天体观测”“宇航技术”“可替代能源”这类词汇

　　我就可以想象出考生的表情。

　　我的论证思路是:主体段先论述为什么有些专家建议联系外星人，这里面会隐隐透露出他们的无知和自大。此外，地球所处的大环境和面临的些严峻问题也会促使人们联系外星人。

　　接下来的另一个主体段就需要严肃地批评这种观点了，因为我认为寻找外太空智能生命这种行为很危险。解释清楚这个危险性之后，就可以总结了。因此，无论出于什么目的，以现在的情况来看不联系外星人オ是上上策。
