1、Unit 4 Space Exploration-Reading and Thinking（Space:The Final Frontier）Are we alone?Whats out there?People have always looked up at the stars and wondered about space.Today,scientists design vehicles to carry astronauts into space to make important discoveries.Space exploration has come a long way,a
2、nd we now hope to discover other planets that are suitable enough to support life.“我们是孤家寡人吗?外面还有什么呢?”一直以来，人们仰望星空，对太空充满了遐想。如今，科学家们研制出飞行器，将宇航员送入太空，去获得重大发现。太空探索已经取得长足的发展，而现在，我们希望发现能够维持生命存在的其他行星。Before the mid-20th century,most people felt travelling into space was only a dream that could never come tru
3、e.However,scientists were determined to realise that dream.After many experiments,they succeeded in making rockets that could escape Earths gravity.On 4 October 1957,the Sputnik 1 satellite was launched by the USSR and successfully orbited around Earth.Afterwards,the USSR focused on sending people i
4、nto space,and on 12 April 1961,Yuri Gagarin became the first person in the world to enter space.二十世纪中叶之前，大部分人认为在太空旅行是一个永远无法实现的梦。然而，科学家们下定决心要实现这个梦想。无数次实验之后，他们终于成功研制出能够摆脱地心引力的火箭。1957年10月4日,“旅伴一号”人造卫星在苏联发射升空，并成功环绕地球运行。之后，苏联专注于载人太空飞行。1961年4月12日，尤里加加林成为世界上进入太空的第一人。B.1.Yuri Gagarin became the first person

10、能够持续在太空中开展工作。Although scientists try to make sure nothing goes wrong,accidents can still happen.For example,all the astronauts on the Soyuz 11,Challenger,and Columbia spacecrafts died during their missions.However,while such disasters brought much sadness and disappointment,the desire to explore the
11、 universe did not die.This is because people believe in the importance of carrying on space exploration despite the huge risks.虽然科学家们极力确保万无一失，但事故仍时有发生。例如，“联盟11号”“挑战者号”和“哥伦比亚号”宇宙飞船上的宇航员们在执行任务时全部遇难。然而，尽管这样的悲剧使人倍感伤心与失望，探索宇宙的渴望永不磨灭。这是因为哪怕风险巨大，人类还是坚信太空探索极为重要。Chinas space programme started later than thos

13、 Chinese spacewalk,followed by the vehicle Jade Rabbit being sent to the moon to study its surface.中国的太空项目起步晚于俄罗斯和美国，但在短时间内发展迅速。2003年，杨利伟乘坐“神舟五号”宇宙飞船成功环绕地球运行，中国成为世界上第三个能够独立将人类送入太空的国家。之后，“神舟六号”和“神舟七号”分别完成了第二次载人环绕地球飞行和中国人的第一次太空漫步。紧接着，“玉兔号”月球车飞抵月球，开展月球表面研究。On 23 July 2020,China sent Tianwen 1 to explor

15、.This modern space station will allow astronauts to conduct many important experiments,greatly furthering our understanding of the universe.2020年7月23日，中国发射“天问一号”探测火星表面。它于2021年2月抵达，随后发回大量有价值的信息。从2021年到2022年，中国完成了多次火箭(发射)任务，建立了自己的空间站。2022年“梦天”太空舱的发射标志着天宫空间站基本建成。这个现代化的空间站使得宇航员们能够开展很多重要实验，从而大大加深我们对宇宙的了解
16、。The future of space exploration remains bright.Many countries have plans to further study planets like Mars and Jupiter.Despite the difficulties,scientists hope to make more valuable discoveries that will enable the human race to survive well into the future.太空探索的未来仍然是光明的。很多国家都已制订计划，将进一步研究火星、木星等行星。
17、尽管困难重重，科学家们希望获得更多有价值的发现，让人类延续生存，直到未来。1.抬头看 2.做出重大发现 3.适合做某事 4.实现 5.下定决心 6.实现梦想 7.成功的 8.逃离地球引力 9.绕地轨道 10.专注于 11.踏上月球 12.传输数据 13.确保一切正常 14.相信 15.继续 16.晚于 17.取得重大进展 18.送回 1.抬头看 _2.做出重大发现 _3.适合做某事 _4.实现 _5.下定决心 _6.实现梦想 _7.成功的 _8.逃离地球引力 _9.绕地轨道 _look up atmake important discoveriesbe suitable to docome t
