For thousands of years, people looked up at the stars and wondered what was out there. In 1961, Yuri Gagarin became the first human to travel into space. His journey 11_____ the door to a new era of space discovery. Since then, many countries have sent astronauts and satellites into space. One of the most famous projects is the International Space Station (ISS). It orbits the Earth every 90 minutes, allowing scientists to do experiments that are 12____ on Earth. For example, studying how plants grow in zero gravity can help us grow food in space in the future. However, space exploration is not easy. Astronauts face many dangers, such as radiation and the risk of equipment failure. They also have to deal with loneliness, as they are 13____ from their families for months. Despite these challenges, they keep working hard because they believe space research can bring benefits to all humans. In recent years, China has made great progress in space exploration. From Chang'e lunar probes to Tianwen Mars rover, Chinese scientists and engineers have shown the world our 14____. These achievements not only improve our scientific knowledge but also inspire young people to 15____ careers in science and technology. What’s next? Scientists plan to build a lunar research station and even send humans to Mars in the coming decades. Though the road ahead is long and difficult, the spirit of exploration will never stop. As we look up at the night sky, we know that the universe still holds countless secrets 16____ us to discover. Space exploration teaches us that no goal is too far if we work together. It reminds us that humans are curious by nature, and this curiosity drives us to 17____ beyond our limits. Every small step in space leads to giant leaps for mankind. Now, more and more students are interested in astronomy. They join science clubs, watch documentaries about space, and even build model rockets. This growing interest is a good sign—it means the next generation is ready to 18____ the torch of exploration. In conclusion, space exploration is not just about reaching new places; it’s about understanding our place in the universe. It brings people from different countries together and encourages us to protect our own planet while looking 19____ the stars. The journey has just begun, and the best is yet to come.

Its reddish color comes from iron oxide (铁锈) on its surface. For years, scientists have wondered: Is there life on Mars? In 2021, NASA’s Perseverance rover landed on Mars. Its main job is to search for signs of ancient life. The rover collects rock samples from areas that were once riverbeds or lakes billions of years ago. If these rocks contain certain chemicals or fossils, it could prove that tiny life forms once lived on Mars. One challenge is that Mars has a thin atmosphere, which lets in harmful radiation from the sun. This makes it hard for life to survive on the surface today. However, some scientists think life might exist underground, where it’s protected from radiation. Perseverance also tests technology to make oxygen from Mars’ carbon dioxide air. This is important for future human missions—astronauts will need oxygen to breathe and to make fuel for returning to Earth. China’s Tianwen-1 mission, which includes the Zhurong rover, also studies Mars’ surface and weather. Together, these missions help us learn more about our neighbor planet and whether it could support life in the past or future. 21. Why is Mars called the "Red Planet"? A. Because it has red oceans. B. Because of iron oxide on its surface. C. Because it reflects red light from the sun. 22. What is the main purpose of NASA’s Perseverance rover? A. To collect rocks for building materials. B. To search for signs of ancient life. C. To build a base for human living. 23. Where might life possibly exist on Mars today according to the passage? A. On the surface. B. In the atmosphere. C. Underground. 24. How can Perseverance help future human missions to Mars? A. By making oxygen from Martian air. B. By sending water back to Earth. C. By planting trees on Mars. 25. Which of the following is TRUE about the Tianwen-1 mission? A. It only carries the Zhurong rover. B. It studies Mars’ surface and weather. C. It landed on Mars in 2020. Ⅴ. 语法填空 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 The Shenzhou-19 spacecraft successfully launched on October 30th, 2024, sending three astronauts to the Tiangong Space Station. This mission 26____ (last) about six months, during which the astronauts will do many scientific experiments. Life in space is quite different from that on Earth. For example, astronauts must tie themselves to the bed while 27____ (sleep), or they will float around! Food in space is also special—most meals are dried and need to be mixed with water before eating. Fresh fruits and vegetables are rare treats 28____ (send) by supply ships. One of the most important tasks for the Shenzhou-19 crew is spacewalk. During a spacewalk, astronauts wear thick spacesuits to protect 29____ (they) from extreme temperatures and radiation. They use special tools to repair equipment outside the station. Each spacewalk usually lasts 6–8 hours, requiring great physical 30____ (strong) and focus. Exercise is necessary every day in space. Without it, astronauts may lose muscle and bone density quickly in the 31____ (weigh) environment. The station has treadmills and exercise bikes, and astronauts spend at least two hours exercising daily 32____ (keep) fit. The mission also includes educational activities. The astronauts will give live lessons to students on Earth, explaining basic science concepts through fun space experiments. These lessons aim to inspire young people’s interest 33____ space science. Thanks to advanced technology, communication between the space station and Earth is smooth. Astronauts can video chat with their families every week, which helps reduce homesickness. As they orbit the Earth 16 times a day, they see 34____ sunrise every 90 minutes—what an amazing view! The Shenzhou-19 mission shows China’s growing ability in space exploration. It is not only a step forward for science but also a symbol of human curiosity and courage.
