I believe there are quite a few benefits. First, it will be a good place for scientists 36 (cooperate) and do space research together. New technologies 37 (can develop), tested and operated there, and these technologies can then be used 38 (build) stations on Mars. Second, more resources 39 (find) on the moon in the future. It will just take time for scientists to find 40 (they). Third, people may live and work there, and even 41 (spend) holidays in space! 42 (follow) the example of great scientists, more students will study science hard. Humans have achieved many things that were once only dreams. Building a station on the moon may take 43 (hundred) of years, but our dreams will come true if we keep 44 (try). 45 dreamers never stop, the future will be bright. 02 Space exploration plays an important role in modern science. During 46 15th Five-Year Plan period, China’s National Space Science Center will carry out a series of new satellite tasks, focusing on major frontiers (前沿领域) of space and the origin (起源) of life in the universe. Two key programs are Hongmeng and Kuafu-2. 47 (design) for the far side of the moon, the Hongmeng Program is made up of ten small satellites working together as a powerful team. Kuafu-2 will be the first satellite 48 (fly) over the polar (极地的) areas around the sun to collect valuable space information and send it back to Earth for further study. Since 2011, China’s space science program 49 (launch) eight advanced satellites in total. Great progress has been made in this field, bringing many new 50 (discover) of outer space. China keeps making its space research 51 (good) than before and has changed from “following others” to “keeping pace” in many high-tech fields. International 52 (cooperate) matters greatly in space exploration. Scientists work 53 (close) with research teams from different countries. All countries should unite together 54 space science can develop much faster. More new space projects 55 (carry) out in the near future to help humans explore more unknown secrets of the universe. 03 A piece of spotted (有斑点的) rock on Mars may show that life once existed there. In 2024, NASA’s Mars rover “Perseverance” dug into this rock. It is in 56 old, dry river bed on Mars. Scientists named the rock “Sapphire Canyon (蓝宝石峡谷)”. Perseverance’s job is 57 (find) signs of old life on Mars, collect rocks and soil samples (样品), and get them ready to bring back to Earth. Sending 58 (rocket) to bring the samples back is one of the biggest tasks. The rover looked at Sapphire Canyon and found 59 (mystery) things in the rock. These could be from very old living things. The rock has two special chemicals. On Earth, these chemicals often come 60 small living things or things that rot (腐烂). Scientists call these clues “potential biosignatures (潜在的生物特征)”, 61 these chemicals can also form in other ways, like very high heat. It is 62 (possible) to know for sure what made the spots until we get the rock sample back to Earth. A plan to bring the samples back is called the Mars Sample Return Mission. This mission 63 (require) a lot of hard work, but its details are not ready yet. The mission is very important, so it is being 64 (work) on carefully. We can’t 65 (complete) know if there was life on Mars, but these clues make us want to keep exploring. We hope to learn more about Mars’ past. 04 For a long time, scientists have known that the universe 66 (fill) with stars. In more recent times, however, thousands of “exoplanets” have also been 67 (discover). These are planets that 68 (move) around stars—just like in our own solar system. So far, more than 5,000 exoplanets 69 (be) known to us, and as technology improves, many more 70 (find). Some exoplanets are similar to Earth. They are of a similar size and temperature, and they might have water. Scientists are excited about this. It 71 (think) that if there is water, there might also be alien life! At present, even a journey to the planet Mars 72 (take) around six to nine months. Scientists never stop trying. New technology 73 (develop) right now. In time, however, it seems possible that humans 74 (reach) the stars as people once 75 (dream). 05 Since the Tiangong Space Station was completed, many scientific experiments have been carried out there. It is now well 76 (know) that working in space is both challenging and exciting. Thousands of exoplanets have been 77 (discover) beyond our solar system, and studying them helps us understand the universe better. The Xuntian telescope, which 78 (weigh) about 15,550 kilograms, will play a key role in this research. Astronauts can move around easily by 79 (push) against the walls in the weightless environment. However, living in space is not always easy. During sleep, they must be 80 (tie) to their beds to avoid floating away. All their food is 81 (prepare) on Earth and kept in special bags to prevent it from floating. In the coming years, more advanced telescopes and rovers will be 82 (launch) into space. They will be 83 (require) to take clear pictures and collect data from distant planets. Space equipment must also be regularly 84 (check) by astronauts during spacewalks. Many young people dream of 85 (explore) Mars or the moon one day. With new technology, these dreams may soon become reality. Perhaps one day, humans will find a new home beyond Earth. 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ Unit 6 Beyond Earth 单词词形、词性转换练习 【单句+语篇共85小题，限时60分钟】 一、用所给单词的适当形式填空 1.

It is now well 76 (know) that working in space is both challenging and exciting. Thousands of exoplanets have been 77 (discover) beyond our solar system, and studying them helps us understand the universe better. The Xuntian telescope, which 78 (weigh) about 15,550 kilograms, will play a key role in this research. Astronauts can move around easily by 79 (push) against the walls in the weightless environment. However, living in space is not always easy. During sleep, they must be 80 (tie) to their beds to avoid floating away. All their food is 81 (prepare) on Earth and kept in special bags to prevent it from floating. In the coming years, more advanced telescopes and rovers will be 82 (launch) into space. They will be 83 (require) to take clear pictures and collect data from distant planets. Space equipment must also be regularly 84 (check) by astronauts during spacewalks.
