Reading and ThinkingSPACE: THE FINAL FRONTIER太空：最后的边境“Are we alone? What’s out there?” Looking up at the stars, people have always wanted to learn more about space, and scientists work hard to find answers. They make“我们是否孤独？太空以外是什么？”仰望星空，人们一直想更多地了解太空，科学家们也在努力寻找答案。
他们制造运载勇敢的人儿进入太空的交通工Before the mid-20th century, most people felt travelling into space was an impossible dream. However, some scientists were determined to help humans realisewas lunched by the USSR and successfully orbited around Earth. Afterwards, the USSR focused on sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to go into space. 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 giant leap for mankind.” Following this, many more goals were achieved. For example, America’s NASA space agency launched Voyager 1 on 5 September 1977 to study deep space, and it still transmits data today.在20世纪中叶之前，大多数人都认为进入太空是不可能实现的梦想。
然功制造出能逃脱地球引力的火箭。
1957年10月4日，苏联发射了人造卫星“旅伴一号”，并成功环绕地球运行。
此后，苏联将重点放在将人类送入太空，1961年4月12日，尤里·加加林成为世界上第一个进入太空的人。
八年后的1969年7月20日，美国宇航员尼尔·阿姆斯特朗登上月球，他说过一句名言：“对一个人来说，这是一小步；对于人类来说，这是一次巨大飞跃。
”在此之后，又实现了更多的目标。
例如，国家航空与航天局于1977年9月5日发射了“旅行者一号”，用于研究外太空，如今它仍在传输数据。
happen. All the astronauts on the USSR’s Soyuz 11 and America’s Challenger died during their missions. These disasters made everyone sad and disappointed , but the desire to explore the universe never died. This is because people believe in the importance of carrying on space exploration despite the huge risks. An example of this ongoing work is the International Space Station. It orbits Earth and has astronauts from different countries on board, providing a continuous human presence in space.尽管科学家努力确保万无一失，但是意外还是可能发生。
苏联“联盟11号”和美国“挑战者”号航天飞机上的所有宇航员都在执行任务时死亡。
这些灾难让每个人都感到悲伤和失望，但是探索宇宙的渴望却从未停止过。
是因为人们坚信太空探索的重要性，哪怕面临巨大的风险。
仍在工作的一个例子是国际空间站。
它绕地球运转，并有来自不同国家的宇航员在宇宙飞船上，为太空提供了持续的人类存在。
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 toindependently 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. After that, China launched the Tiangong 2 space lab into space and Tianzhou1 to dock with it. This signalled one step further in China’s plan to establish a space station in the future. More recently, China has sent Chang’e 4 to explore the surface of the far side of the moon to make measurements and observations.中国的太空计划起步晚于俄罗斯和美国，但中国在短时间内取得了巨大进展。
2003年，杨利伟乘坐神舟五号成功绕地球飞行，中国成为世界上第三个实现载人航天的国家。
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，随后，“玉兔”月球车被送上月球研究其表面。
之后，中国将天宫二号空间实验室送入太空，天舟一号与其交会对接。
这标志着中国在未来建立空间站的计划又向前迈进了一步。
最近，中国发射嫦娥四号探测月球背面，以进行测量和观察。
have plans to further study and explore planets like Mars and Jupiter. Despite the difficulties, scientists hope future discoveries will not only enable us to understand how the universe began, but also help us survive well into the future.星和木星等行星。
尽管困难重重，科学家们希望未来的发现不仅能让我们了解宇宙的起源，而且还能帮助我们更好地在未来生存。
Reading and WritingIS EXPLORING SPACE A WASTE OF TIME AND MONEY?探索空间是否浪费时间和金钱？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.无论是去火星还是其他更遥远的星球，世界各国都在花费数十亿美元和大量时间在各种太空使命上。
有人认为我们应该停止浪费时间和金钱来探索太空。
相反，我们应该为世界上的穷人提供食物，并立即解决其他问题，例如污染和致命疾病。
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。
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，探索空间在在消除世界饥饿的斗争中发挥了作用。
