SPACE：THE FINAL FRONTIER
“Are we alone？What's out there？” People have always looked up at the stars and wondered about space．[1] Today，scientists design vehicles① to carry astronauts into space to make important discoveries．
Space exploration has come a long way，and we now hope to discover other planets that are suitable enough to support life．
［1］本句是简单句，and连接的是并列谓语。
Before the mid-20th century，most people felt travelling into space was only a dream that could never come true．[2]However，scientists were determined② to realise that dream．After many experiments，they succeeded in making rockets that could escape Earth's gravity．On 4 October 1957，the Sputnik 1 satellite was launched by the USSR and successfully orbited around Earth．Afterwards，the USSR focused on③ sending people into space，and on 12 April 1961，Yuri Gagarin became the first person in the world to enter space．[3] Over eight years later，on 20 July 1969，American astronaut Neil Armstrong stepped onto the
moon，famously saying，“That's one small step for [a] man，one giant④ leap⑤ for mankind．[4]” Following this，there were many more important space achievements．For example，on 5 September 1977，America's NASA space agency launched Voyager 1 to study deep space，and it still transmits⑥ data to this day．And the International Space Station (1998) has provided a continuous human presence in space，with astronauts from many different countries on board⑦．
[2]本句是复合句。felt后是省略了that的宾语从句，该从句中动词-ing形式短语travelling into space作主语，that could never come true为定语从句。
[3]该句中the first person in the world to enter space为“the＋序数词＋名词＋动词不定式”结构。
[4]这是1969年美国宇航员尼尔·阿姆斯特朗登月成功时所说的一句名言，充分表达出这次登月成功是人类太空探索的重要里程碑。
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 desire⑧ to explore the universe did not die．[5]This is because people believe in⑨ the importance of carrying on⑩ space exploration despite the huge risks ．
[5]该句中while引导让步状语从句，不定式短语to explore the universe作desire的后置定语。
China's space programme started later than those of Russia and the US，but it has made great progress in a short time．China became the third country in the world to independently send humans into space in 2003，when Yang Liwei successfully orbited Earth in the Shenzhou 5 spacecraft．Then Shenzhou 6 and 7 completed a second manned orbit and the first Chinese spacewalk，followed by the vehicle Jade Rabbit being sent to the moon to study its surface．On 23 July 2020，China sent Tianwen 1 to explore the surface of Mars．It arrived in February 2021 and then sent back lots of valuable information．And from 2021 to 2022，China completed a number of rocket missions to establish its own space station．In 2022，the launch of the Mengtian module signaled the basic completion of the Tiangong Space Station．This modern space station will allow astronauts to conduct many important experiments，greatly furthering our understanding of the universe．
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：最后的边境
“我们是孤家寡人吗？外面还有什么呢？”人们总是仰望星空，对太空充满好奇。今天，科学家们设计运载工具将宇航员送入太空，期待取得重大发现。太空探索已经取得了长足的进步，我们现在希望能发现其他适合生命生存的行星。
二十世纪中叶之前，大部分人认为在太空旅行只是一个无法实现的梦。然而，科学家决意要实现这个梦想。无数次实验之后，他们终于成功研制出了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。八年多之后，美国宇航员尼尔·阿姆斯特朗于1969年7月20日踏上月球，说出了那句名言：“对一个人来说，这是一小步；对人类来说，这是一大步。” 此后，还有许多更重要的太空成就。例如，1977年9月5日，美国国家航空与航天局发射了“旅行者一号”来研究外太空，直到今天它还在传输数据。国际空间站(1998年)使得人类能够持续在太空中开展工作，站内的宇航员来自不同国家。
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”的宇航员们在执行任务时全部遇难。然而，尽管这些悲剧使人倍感伤心与失望，探索宇宙的愿望并没有破灭。这是因为人们坚信继续探索太空的重要性，哪怕面临巨大的风险。
中国的太空项目起步晚于俄罗斯和美国，但在短时间内已经取得了巨大进步。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。此后，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以及中国人的第一次太空行走。紧接着，“玉兔”月球车飞抵月球，开展月球表面的研究工作。2020年7月23日，中国发射了“天问一号”探测火星表面。它于2021年2月抵达火星，之后发回了许多有价值的信息。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，梦天实验舱的发射标志着天宫空间站的基本建成。这个现代空间站将允许宇航员进行许多重要的实验，极大地促进了我们对宇宙的了解。
太空探索的未来仍然是光明的。许多国家计划进一步研究火星、木星等行星。尽管困难重重，科学家们希望做出更多有价值的发现，使人类能够在未来生存得更好。
