16、ght. A Although scientists try to make sure nothing goes wrong, accidents can still happen. All the astronauts on the USSRs Soyuz 11 and Americas Challenger died during their missions.

17、ause 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. Main idea: Despite

18、the huge risks, humans still desire to explore space. Chinas 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 orbite

19、d 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.

20、This signalled one step further in Chinas plan to establish a space station in the future. More recently, China has sent Change 4 to explore the surface of the far side of the moon to make measurements and observations. _ Europe, the US, and China all have plans to further study and explore planets

21、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. C.
