Polish your writing Thank you Is exploring space a waste of time and money? 1 Countries around the globe are spending billions of dollars and lots of time on various space missions, whether to Mars or other planets much further away. Some people argue that we should stop wasting time and money exploring space. Instead, we should feed the world's poor and find immediate solutions (to other problems), such as pollution and fatal diseases. However, others feel this is a shallow view which fails to realise how exploring space helps us. 全球各国正投入数十亿美元和大量时间开展各类太空任务，无论是前往火星还是更遥远的行星。一些人认为我们应该停止浪费时间和金钱去探索太空，而应该去养活世界上的贫困人口，并立即解决其他问题，比如污染和致命疾病。然而，另一些人则认为这种观点很肤浅，没有意识到探索太空对我们有何帮助。 2 Firstly, exploring space has already made a difference in the fight against world hunger. It has directly resulted in the many satellites that now orbit Earth. A number of the satellites record data on land and weather patterns. Then the data is transmitted to scientists on Earth. After careful analysis, the scientists can provide useful recommendations and advice for farmers. As a result, space-based science has helped farming in its efforts to grow enough food [to feed Earth' s increasing population]. 首先，太空探索已经在对抗世界饥饿的斗争中发挥了重要作用。它直接促成了如今环绕地球运行的众多卫星。其中不少卫星负责记录陆地和天气模式的数据，随后这些数据会被传回地球上的科学家。经过仔细分析后，科学家们能为农民提供实用的建议和指导。因此，基于太空的科学技术帮助农业提高了粮食产量，以满足地球上不断增长的人口需求。 3-1 Secondly, space exploration has already promoted technological improvements that benefit us all. High-end products around the world are made to a higher standard now[ because of advanced technology which was first created to meet the requirements for space exploration]. 其次，太空探索已经推动了惠及我们所有人的技术进步。由于最初为满足太空探索需求而研发的前沿技术，如今全球的高端产品都达到了更高的制造标准。 3-2 For example , space technologies have helped the research and development of different types of new material. They have also helped companies make better heart monitors and other machines that doctors regularly use. Today, space technologies are widely used in all kinds of industries, and everyday products, such as GPS, memory foam pillows, and smartphone cameras, are changing our lives. 例如，太空技术助力了各类新材料的研发，还帮助公司制造出更优质的心脏监护仪及其他医生日常使用的医疗设备。 如今，太空技术已广泛应用于各行各业，像GPS导航、记忆海绵枕头、智能手机摄像头等日常产品，正在悄然改变我们的生活。 4 Finally, sending astronauts into space / has helped people to think about the world's problems and even to find ways (to solve them). Seeing pictures of our planet as an island in a black sea /made people realise/ that our planet's resources are limited. In order to provide for such a rapidly increasing population, scientists are trying to find other planets that could one day be our new home. The greatest attention at present is on Mars because it is closer to Earth. In the future, humans may live on both planets. 最后，将宇航员送入太空帮助人们思考全球性问题，甚至找到解决办法。当看到地球如黑海中的一座孤岛的照片时，人们意识到地球资源是有限的。为了养活如此快速增长的人口，科学家们正努力寻找有朝一日能成为我们新家园的其他星球。目前最受关注的是火星，因为它离地球更近。未来，人类或许能在两个星球上生活。 Seeing pictures of our planet as an island in a black sea /made people realise/ that our planet's resources are limited. 当看到地球如黑海中的一座孤岛的照片时，人们意识到地球资源是有限的。 5 In closing, exploring space provides the world with many different benefits. Therefore, it should continue [so as to provide new and better solutions to people's short-term and long-term problems.] 总之，探索太空为世界带来了诸多益处。因此，我们应当继续推进太空探索，从而为人们短期和长期面临的各种问题提供更新、更好的解决方案。 $
