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 Space: The Final Frontier Para1:People are curious about space Task3:Structure : Dream Reality Future Title: Introduction: Body: Conclusion: 23 Sample Writing Everyone gets excited by the news of the most recent space flights, and I too share in people’s sense of awe. However, I cannot understand spending all this money on expensive research and experiments. Some people argue that the world will be made impossible to live in through pollution. This seems silly. When your house gets dirty, you spend the time and money to clean it up. You don’t move house simply because you need to clean the floor. It makes more sense to use our time and money to take care of our planet, rather than look for a new home. In closing, it just does not seem a very wise investment to go to space, since we have so many needs here on the earth to meet. topic opinion Argument Supporting details/Evidence Conclusion Ever since space research began, it has been criticized as a huge waste of money and other resources. In my opinion, despite the disadvantages and potential dangers, the advantages are far greater. Exploring space has already made a difference in the fight against world hunger. The scientists have discovered a new agricultural model, Space Farm, to grow crops, which can improve the output and quality of crops. What’s more, sending astronauts into space has helped people to think about the world’s current problems and even to find ways to solve them. In closing, exploring space contributes not only to the improvement of quality of human life, but also to our understanding of all the creatures. Sample Writing topic opinion Argument 1 Supporting details/Evidence Argument 2 Conclusion Do you know it’s hard to hear in the space? Stardust is silent. But the every step we take sounded in the universe. The sound you make can be heard in space. $$
