13、独的吗?那里是什么?”人们一直想更多地了解太空，而且科学家在努力工作寻求答案，为了查明字宙的秘密他们制做了交通工具把那些勇敢的人带到太空找出宇宙的秘密。他们也真的希望能发现其他适合生命生存的行星。在20世纪中期以后，绝大多数人认为太空旅行是不可能的。然而，一些科学家决意要帮助人类实现探索太空的梦想。经过多次实验之后，他们成功地造出了能够逃脱地球引力的火箭。在1957年10月4日，苏联成功发射了 Sputnik1号卫星，且成功地实现了让卫星绕地球运转。后来苏联专注于研究送人类进入太空(这个问题)并且在1961年4月12日，尤里加加林成为世界上进入太空的第一人.八年之后，也就是在1969年7月20
14、日，美国宇航员尼尔阿姆斯特朗登上月球，说了一句著名的话，“对一个人来说，这是一小步;对人类来说，这是一大步。”随之而来的是，许多目标都实现了。例如，为了研究外层空间，美国航空航天局在1977年9月5日发射了航行者1号，时至今日它仍然在传送一些数据。虽然科学家竭力确保不出任何错误，但事故仍然可能发生。在执行任务期间，在苏联的联盟者11号和美国的挑战者(飞船上)的所有宇航员全部遇难。这些灾难让每个人感到悲伤和失望，但是(人们)探索字宙的渴望从未泯灭。这是因为人们坚信太空探索的重要性，哪怕面临巨大的风险。这种继续努力的一个例子就是国际太空站。它绕地球运行，允许来自不同国家的字航员搭乘，让入类持续不断
15、地出现在太空中。中国的太空计划开始得比俄国和美国都晚。但是在短时间内取得了很大进步，在2003年，中国成为世界上第三个独立自主把人类送入太空的国家，当时杨利伟在神舟五号字宙飞船里成功地绕地球运行。此后神舟六号和七号分别完成了第二次载人飞行以及中国人的第一次太空行走，紧接着月球探测车玉兔也被发射到月球去研究其表面。之后中国把天宫二号太空实验室送入太空，并且与天舟号实现对接。这标志着中国未来建立空间站的计划又前进了一步。最近，为了做好测量和观测，中国已经发射了嫦娥四号去探测月球离我们较远的那一边的表面。字航探索的未来充满光明，欧洲、美国和中国都有计划要进步研究和探索像火星和木星这样的行星。尽管困难
16、重重，科学家们希望未来的发现不仅能够使我们了解字宙的起源，而且还帮助我们更好地走向未来。Unit4 Reading for Writing (P44)IS EXPLORING SPACE A WASTE OF TIME OR MONEY?Countries around the1._(地球；世界；地球仪)arespendingbillionsofdollars and lots of time2._various spacemissions,whetherto Mars3._ other planetsmuch 4._(far) away.

26、然而，其他人则认为这是一个肤浅的观点，没有意识到探索太空对我们的帮助。 首先，探索空间在在消除世界饥饿的斗争中发挥了作用。它直接影响现在绕地球飞行的许多卫星。许多卫星记录着陆地和天气模式的数据。然后，这些数据被传送到地球上的科学家。经过仔细分析，科学家们可以为农民提供有用的建议。因此，太空技术帮助农业努力种植足够的食物来养活地球上不断增长的人口。 其次，太空探索促进了造福于我们所有人的技术进步。由于先进的技术首次被提出以满足太空探索的需求，因此现在世界各地的高端产品都达到了更高的标准。例如，空间技术有助于研究和开发不同类型的新材料。它们还帮助公司制造了更好的心脏检测仪和医生经常使用的其他仪器。如今，太空技术已广泛应用于各个行业，并且诸如全球定位系统、记忆泡沫枕头和智能手机相机之类的日常用品正在改变我们的生活。 最后，将宇航员送入太空帮助人们思考世界上的问题，甚至找到了解决问题的方法。看到我们的星球在黑海中作为一个岛屿的照片让人们意识到我们星球的资源是有限的。为了满足如此迅速增长的人口，科学家们正在努力寻找其他行星，这些星球将来可能成为我们的新家。目前最受关注的是火星，因为它离地球更近。在未来，人类可能生活在两个星球上。 最后，探索太空为世界带来许多不同的好处。因此，它应该继续下去，以便为人们的短期和长期问题提供新的和更好的解决方案。5学科网（北京）股份有限公司
