35、寻求答案，为了查明宇宙的秘密他们制做了交通工具把那 些勇敢的人带到太空。他们也真地希望能发现其他适合生命生存的行星。在二十世纪中期以后，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 Sputnik 1号卫星，且卫星成功地绕地球运转。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

36、；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，时至今日它仍然能传送一些数据。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号和美国白挑战者（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）探索宇宙的渴望从未泯灭。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 家的宇航员搭乘，让人类持续不断地出现在太空中。中国的太空计划开始的比俄国和美国都晚。但是在短时间内取得

37、了很大进步，在2003年,中国成为世界上第三个独自把人类送入太空的国家，当时杨利伟在神舟五号宇宙飞船里成功 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，并且与天舟一号实现对接。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。宇航探索的未来充满光明，欧洲、美国和中国都有计划要进一步研究和探索像火星和木 星这样的行星。尽管困难重重，科学家们希望未来的发现不仅能够使我们了解宇宙的起源，

38、而且还帮助我们更好地进入未来。理解课文精研读U表层理解a速读课文，完成下列任务I .单项选择阅读P4041课文内容，选择最佳选项1. What does the scientist do to find out the secrets of the universe?A. Look up at the stars.B.
