After many experiments, they succeeded in making rockets that could escape Earth’s gravity. Original text： “Are we alone? What's 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. B Before the mid-20th century, most people felt travelling into space was only a dream that could never come true. However, scientists were determined to realise that dream. 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 into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to enter 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, 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 transmits data to this dav. And the International Space Station (1998) has provided a continuous human presence in space, with astronauts frommany different countries on board.A D 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 universe did not die. This is because people believe in the importance of carrying on space exploration despite the huge risks. 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.C 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. Activity 4 Guess the type of the text A. Narrative writing(记叙文) B. Argumentative essay(议论文) C. Popular science article(科普文章) D. Practical writing(应用文) Activity 5 Match the main idea Para.1 People’s dream of space exploration came true in the 20th century. Para.2 People are always be curious about space, and scientists work hard to find answers. Para.3 The future of space exploration remains bright. Para.4 China’s space programme has made great progress in a short time. Para.5 Despite the disasters humans still desire to explore space. Answer to Activity 5 Para.1 People’s dream of space exploration came true in the 20th century. Para.2 People are always be curious about space, and scientists work hard to find answers. Para.3 The future of space exploration remains bright. Para.4 China’s space programme has made great progress in a short time. Para.5 Despite the disasters humans still desire to explore space. Activity 6 Fill in the blank with the correct words. orbit mankind frontier launch gravity board universe _______ is exploring space in the hope of finding out more about the ________. However, exploring space is both dangerous and challenging. One of the most dangerous parts of space exploration is helping people to escape Earth's _________. If there is a mistake during the __________, it can lead to an accident that kills everyone on __________. Getting out of _________ and back to Earth’s surface is also very dangerous. Despite the huge risks though, people will always continue to explore this final _________ so as to learn its secrets. Answer to Activity 6 orbit mankind frontier launch gravity board universe Mankind is exploring space in the hope of finding out more about the universe. However, exploring space is both dangerous and challenging. One of the most dangerous parts of space exploration is helping people to escape Earth’s gravity. If there is a mistake during the launch, it can lead to an accident that kills everyone on board. Getting out of orbit and back to Earth’s surface is also very dangerous. Despite the huge risks though, people will always continue to explore this final frontier so as to learn its secrets. Activity 7 Further thinking Is it worth the time and money to explore space? Activity 8 Homework 1. Try to organize your words about the question in “post-reading” Is it worth the time and money to explore space? 2.
