题目：
Some people believe that spending money on developing technology for space exploration is unjustifiable as there are more beneficial ways to spend money. To what extent do you agree or disagree? 2018年纸考原题
有些人认为花钱开发太空探索技术是不合理的，因为有更有益的花钱方式。你在多大程度上同意或不同意?
这个题目近来考的三次分别是在：0204广州、0203武汉、0119。
这个话题难度不大，话题最常考的焦点就是太空探索的意义：人类明明知道太空探索有这么多负面的问题，为什么还是要做这件事？
这里主要补充6个优点和5个缺点，再怎么也够考试用了。
而且这些观点素材，都是很简单又贴合生活实际的角度，好理解、好记忆，又扣题。
Pros of Space Exploration
1.It is an opportunity to explore something new.探索新事物
There are so many unanswered questions when we think about space, and there are numerous technological barriers we must cross before we could travel for long distances in the vacuum of space, but we are getting one step closer every day.
太空有太多悬而未决的问题。在太空真空中进行长距离旅行之前，我们必须跨越无数的技术障碍，但我们每天都在向这一目标迈进。
2.It creates numerous employment opportunities in a variety
of fields.创造大量就业
There are more than 18,000 people employed in the United States by NASA, along with countless contractors, freelancers, and specialists not counted in those figures. Then there are the astronauts, engineers, and flight specialists who manage the actual mechanisms of space flight to consider. 承包商、自由职业者、专家、高技能职位、经济领域从业者、管理太空飞行实际机制的宇航员、工程师和飞行专家等
3.It allows us to understand our planet better.更好地了解地球
It gives us a way to track the changes to our environment, study ozone depletion, and measure the impacts of a warming planet. 它为我们提供了一种追踪环境变化、研究臭氧消耗和测量地球变暖影响的方法。
4.It gives us an opportunity to foster international cooperation.
促进国际合作
We work together as the human race to operate the international space station, fund research projects, and look outward beyond the stars to see what is there. 全人类共同运作国际空间站，为研究项目提供资金，并向外看星星之外的世界。
5.It is an effort which requires us to become innovative.不断创新
What we have found in this area of science is that there are numerous discoveries which become possible to improve our lives here at home. 太空领域的发现可以改善我们的生活。
6.It would give us access to new minerals, precious metals,
and other items.获得矿物、贵金属和其他发现
Space exploration gives us an opportunity to access new mineral resources.太空探索使人类有机会获得新的矿产资源。
Cons of Space Exploration缺点
1.It could cause us harm or provide harm to other species in
space.未知伤害
The viruses, bacteria, and potentially unknown invaders could do as much damage to us as we could to do them. 病毒、细菌，以及潜在的未知入侵者，都能造成伤害。
2.It creates high-level pollution.污染
We must consume fossil fuels when we launch rockets into space, which means we’re creating a significant level of pollution every time we expend fuel for exploration purposes. 当我们向太空发射火箭时，我们必须消耗化石燃料，这意味着每次我们为探索目的消耗燃料时，我们都会造成严重的污染。
3.It is expensive to start exploring space.昂贵
Our planet spends about $60 billion per year on this effort. In comparison, the United Nations suggests that it would only take half of that amount to end global hunger permanently. 我们的星球每年在这方面花费大约600亿美元。相比之下，联合国认为只需要这一数字的一半就能永久结束全球饥饿。
4.It will create a large amount of space garbage.产生垃圾
Every item we leave behind creates a future risk for someone else. Should a spaceship encounter that debris, it could be a deadly experience. 我们留下的每一件物品都会给其他人带来未来的风险。如果宇宙飞船遇到这些碎片，那将是一次致命的经历。
5. it may cause our planet to face unknown perils.未知危险
Exploring space could become an invitation for interstellar war. 探索太空可能会引发星际战争。
