Space travel has been possible for some time. Some people think space tourism would develop in the future. Do you think space tourism is a positive or negative development?

题目来源：2017年6月17日大陆雅思大作文1题目大意太空旅行已经成为可能一些人觉得太空旅行在未来会得到发展你认为发展太空旅行是一个积极的还是消极的趋势？2思路解析这是一道利弊类考题，讨论的是发展太空旅行的利弊。

利弊类文章，需要强调在论证上体现合理性，即在具体的分析中，明确能体现出一边的论述的确是大于另一边，或是利弊均等，而利弊是否有说服力并不取决于观点的数量，而是内容是否有说服力题目理解上不难，但有的同学可能会觉得太空探索距离现实太远想不到观点，这里建议可以往我们比较熟知的科技发展、环境问题、资金成本等内容上靠，下面月半鸭和大家来看下具体观点。

首先来看发展太空旅游的坏处，有三方面一是太空旅游的发展会需要投入大量的资金，当国家预算不足时，开发太空旅游可能会占据了原本能用于农业、医疗等领域的资金而发展前者可能只对少数人有益，但后者却关系到大多数普通人的生活甚至是生存。

二是发展太空旅游伴随着安全性问题，就目前技术来看，一旦发生事故，成员生还的几率几乎为0在难以保证生命安全的情况下，推动太空旅游是不负责任的三是频繁的太空旅游可能会消耗大量的能源，以及产生许多不可回收垃圾，这些垃圾会留在陆地、海洋甚至太空中且难以清除，最终造成环境污染。

再来看发展太空旅游的好处，有两方面一方面，太空旅游能够激发人们对于太空探索的兴趣以及给太空探索带来经济收益，进而有更多资金、人才愿意投入到太空相关领域，这对于整个太空技术发展是有利的，并且能带动许多相关产业发展和创造更多就业岗位。

另一方面，太空旅游发展同时会促进许多相关科技的进步，诸如载人技术、安全技术、更高效的能源使用以及制造飞船所需要的新材料等等，这些科技的进步慢慢能够让太空旅游变得更加安全且成本更低，并且许多技术一旦成熟后会被运用到更多的民生领域，对社会整体有益。

3提纲

4高分范文示例Space tourism has always been a fascinating thing for humans. Just like the other tourism like ecotourism, medical tourism, sports tourism, business tourism, etc., space tourism has become successful in gaining the attention of people worldwide. However, whether it will be a boon or ban in the future has caused a heated debate. In my opinion, there are both positives and negatives. 

The first benefit is the jobs that the industry is going to provide. To be specific, with more and more companies are taking an interest into space tourism, a high number of jobs for researchers, scientists, explorers, pilots, programmers, operators, and many other support staff will be available in next few years. Also, to make a space tourism business, shuttles, planes, and many other things will be needed. Therefore, the demand for the particular manufacturing unit will be there and so as the related jobs to it.

Another advantage of space tourism is going to be its ability to renew interest in space and space exploration. With renewed interest, financial backing will follow, and that will support further innovation in the industry and space exploration in general. In this case, the space program will help to know whether human life is possible on Mars or not and many other things in the future.

However, this is not a perfect picture. Every space tour involves significant risk of catastrophic disasters which can result in a loss of human lives. So, the companies have to take care of all the safety concerns and make every prudent step to ensure a safe journey to space, with the extremely hostile environment of the space anything can happen. Moreover, the space industry also creates environmental problems with the launch of space shuttles, satellites, rockets, and other equipment. It also raises the issue of global warming in the world as there are many no recyclable resources used in space tourism programs.

To conclude, whether to develop the space tourism depends on how we see it and how the industry handles it. If the missions are carried out with extreme precautions of safety and other standards, then it will generate a lot of advantages. On the other hand, if it will be held only for the fundraising and just for the pleasure of the eyes to see the universe, then it may end up with the wrong outcome.
