It is the closest planet to Earth and has the most similar environment to our planet. Scientists believe that studying Mars can help humans know the evolution of planets and find possible signs of life outside Earth. China’s Tianwen-1 mission was launched in 2020. It successfully entered Mars orbit and landed the Zhurong rover on Mars in 2021. The rover has worked steadily on Mars for a long time. It takes clear photos of the Martian surface, checks the soil and weather conditions, and collects various scientific data. The data sent back by Zhurong is very valuable. It helps scientists study whether Mars once had water and living things. It also provides important support for future human Mars exploration plans. Mars exploration is not easy. It takes precise technology, huge investment and countless efforts of scientists. But every progress brings humans closer to the truth of the universe. 31. Why do scientists choose to explore Mars? A. It is the farthest planet from Earth. B. It has similar environment to Earth. C. There are humans living on Mars. D. It has complete water resources. 32. When did Zhurong rover land on Mars? A. In 2020 B. In 2021 C. In 2022 D. In 2023 33. What is the value of Mars exploration? A. It helps humans study planetary evolution. B. It allows humans to live on Mars soon. C. It solves all environmental problems on Earth. D. It reduces the cost of space research. （B） Astronauts’ life in space is far from easy. They face many physical and living challenges in the weightless environment. First of all, daily life is totally different. Without gravity, food, water and even books will float in the air. Astronauts have to eat sealed food and fix all daily supplies tightly. They cannot take a shower as we do on Earth. Instead, they use wet towels to clean their bodies. Secondly, weightlessness does harm to their bodies. After staying in space for a long time, astronauts’ muscles will become weak and their bones will lose calcium. To protect their health, they must exercise for at least two hours every day with special fitness equipment. Thirdly, astronauts face great mental pressure. They stay in a narrow space for months, far away from family and friends. They need strong willpower to keep positive. Although space life is tough, astronauts love their jobs. They devote themselves to space exploration for the development of all mankind. 34. What do astronauts use to clean their bodies in space? A. Showers B. Wet towels C. Clean water D. Special soap 35. Why do astronauts exercise every day? A. To relax themselves B. To kill spare time C. To protect their physical health D. To test space equipment 36. Which of the following is NOT the challenge for astronauts? A. Floating daily supplies B. Body discomfort C. Mental pressure D. Free living space 37. What is the best title for the passage? A. The challenges of space life B. How to be a good astronaut C. The fun of living in space D. The future of space travel （C） Many people don’t realize how much space technology changes our daily life. Almost everyone is enjoying the benefits brought by space exploration every day. Satellite technology is the most common example. Navigation satellites guide our driving, cycling and walking trips, making travel more convenient. Weather satellites monitor global weather changes and help people avoid natural disasters. Medical technology also benefits from space research. The special medical monitoring technology used for astronauts is now widely used in hospital treatment. It helps doctors know patients’ physical conditions more accurately. Besides, lightweight and strong materials developed for spacecraft are used in sports suits, safety helmets and building materials. Even the special food preservation technology for space has been used in ordinary food industry. Space exploration is not only a great exploration of the universe, but also a powerful driving force for social progress. It brings endless benefits to human life. 38. What can navigation satellites help people do? A. Predict weather B. Guide travel C. Treat illness D. Protect buildings 39. Which field does space technology help improve? A. Medical treatment B. Forest protection C. Animal feeding D. Farm planting 40. What does the underlined word “preservation” mean? A. 加工 B. 销售 C. 保鲜 D. 运输 41. What is the main idea of the passage? A. The history of satellite development B. How space exploration is carried out C. Space technology’s influence on daily life D. The difficulties of space research （D） International cooperation plays an important role in modern space exploration. No country can master all space technology and complete all space tasks alone. Cooperation makes space exploration faster and more successful. The International Space Station (ISS) is the most typical example. It is built and used by more than ten countries. Scientists from different countries work together there, carry out experiments and share research achievements. They help each other and make progress together. China’s Tiangong space station is also an open international platform. China has invited foreign scientists to carry out space experiments and provides a fair cooperation environment for all countries. It shows China’s responsibility in the space field. Through international cooperation, countries save research cost, share advanced technology and broaden their horizons. It also promotes peaceful communication and friendship between countries. Space exploration has become a common cause of all mankind. 42. Why do countries cooperate in space exploration? A. To reduce research difficulty and cost B. To compete with other countries C. To occupy more space resources D. To build more space stations 43. Which is a typical example of international space cooperation? A. Mars rover B. International Space Station C. Lunar probe D. Space documentary 44. What can we know about Tiangong space station? A. It only serves Chinese scientists B. It refuses foreign cooperation C. It is an open cooperation platform D. It has stopped running 45. What does the passage mainly tell us? A. The history of space station building B. The importance of international space cooperation C. How to develop space technology alone D. The achievements of China’s space industry 五、阅读填空（共5小题，每小题2分，满分10分） 阅读下面短文，从短文后的A~F六个选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。 Space exploration is a lifelong pursuit for human beings.
