Among the three members, much attention was 1 to Wu Fei. Wu Fei, born in 1993, is the 2 astronaut to go to space of China. Before becoming an astronaut, Wu Fei worked as an engineer and 3 . He spent years designing and 4 space equipment. These experiences taught him a lot of 5 skills.  Later, he joined China’s third group of astronauts. During the three-year training, he worked very hard. 6 , his efforts made him stand out and get the chance to join Shenzhou-21. In the Shenzhou-21 mission, Wu Fei acts as a flight engineer. 7 main jobs include checking the spaceship’s equipment, helping with scientific experiments and working with other team members. Though it was his first space trip, he 8 calm and finished all tasks well. He said, “Space is amazing.

So far, Wu Fei has 10 a hero for many young people. His story tells us that hard work can make dreams come true. 一、完形填空 In 2025, China’s space station Tiangong (天宫) became a busy place again. Three astronauts (宇航员) arrived to continue scientific work. Among them was 42-year-old Wang Hao, who was making his first space trip. The team spent six months in space. They did experiments in the microgravity (微重力) environment. One of the most exciting moments was the spacewalk. When Wang Hao first stepped out of the capsule (舱), he felt his heart beating fast. Looking down at the Earth, a beautiful blue planet, he was 1 by its beauty. “It’s something you can never 2 from the ground,” he said later. Life in space was not just about work. They celebrated the Lunar New Year together, hanging red lanterns that 3 in the air. They also had video calls with students on Earth, answering questions about space life. Many young people were 4 to learn how astronauts drink water-it floats in little balls! However, the work was not easy. Every task required 5 training and careful planning.

Have you ever dreamed of floating in space? For people in China, that dream is coming true. From film stars to scientists, more than 20 famous people in China have booked seats on the country’s first commercial (商业的) spaceflight. The tickets are sold by a Beijing-based space company. Each seat costs 3 million yuan. That sounds like a lot, but it is much cheaper than a trip with Elon Musk’s SpaceX, which can cost up to 50 million dollars. To save a seat, passengers must pay 10% ahead. The company plans to send its first passengers into space by 2028. The spaceship, called CYZI, can carry 6 people. After launch (发射), it will separate from the rocket at about 70 kilometers above the ground. Then it will cross the Karman Line, the widely accepted edge of space. After that, it will return safely to Earth with parachutes (降落伞). Some of the passengers include Scientist Li Licheng, Poet Lin Xiaoyan, and Actor Huang Jingyu. In a video released by the company, one passenger said, “The world always needs a few people who are a little crazy.” China is supporting commercial space travel more than ever. In 2025, the China National Space Administration announced (宣布) a plan to give companies more passages to rocket test facilities (设施). Aerospace is also listed as a key industry in China’s latest Five-Year Plan. Other Chinese companies are also joining the race. A host from one company even sold 2 tickets during a livestream. Each ticket required a passenger to pay ¥ 50,000 ahead. Space travel may soon become possible for more people in China. Are you brave enough to join them on a trip to the stars? 1．How does the writer introduce the topic? A．By raising questions. B．By listing numbers. C．By giving an example. D．By making a comparison. 2．What does the underlined word “floating” in paragraph 1 mean? A．Flying. B．Surviving. C．Working. D．Racing. 3．How many people can CYZI carry? A．2. B．6. C．20. D．70. 4．What is Li Licheng? A．A poet. B．An actor. C．A scientist. D．A host. 5．What is the writer’s purpose of writing this text? A．To introduce the Karman Line. B．To describe China’s latest Five-Year Plan. C．To explain the ways to book a space ticket. D．To show the progress of China’s space industry. （2026·江苏扬州·中考真题）What if things in your home—your toothbrush, books, desks, even you!—suddenly seemed weightless and began to float? This is what astronauts experience in a space station—microgravity (微重力). Even though the space station and the astronauts inside are in space, Earth’s gravity is still pulling on them, though very weak. Let’s explore the astronauts’ life in space. Though there are some challenges, life in space is a super-fun. Eating and sleeping Need to get from one place to another? Just push off a surface and glide there! Nothing stays put. Imagine turning on a tap. Water would go flying everywhere. Astronauts aren’t allowed to eat anything in the space station that creates crumbs (碎屑). Food crumbs can become a disaster if they get into equipment (设备). That’s why astronauts eat specially prepared meals. There’s no “up” or “down” in space, so astronauts sleep in sleeping bags tied to the wall. Their arms will float in front of them while they sleep. Astronauts have to keep their bodies strong. There’s less stress on bones in space, for gravity is weaker. Muscles (肌肉) aren’t used as much. Their bones and muscles grow weaker. Even astronauts’ hearts can weaken. Every astronaut has to exercise for about two hours a day. Most of the exercise equipment is specially designed to imitate the feel of gravity. Work and play Astronauts spend much of their time working. They do a lot of experiments—from space life science to new spacecraft technologies. Sometimes they do spacewalks to make repairs to the outside of the station. When they have free time, astronauts kick back by reading books and looking down at Earth. 1．According to the text, what may cause danger to the space station? A．Water in special bags. B．Very tiny food pieces. C．Specially prepared meals. D．Sleeping bags tied to the wall. 2．Which of the following should go in the empty box? A．Exercising for a strong heart. B．Moving freely. C．Dealing with space loneliness. D．Staying strong. 3．What does the text mainly talk about? A．Strange changes to astronauts’ bodies in space. B．Astronauts’ fun and challenging life in space. C．How astronauts do experiments in space environments. D．Why astronauts inside the space station can’t stay put.

Have you ever dreamed of floating in space?”，作者通过提出问题的方式引出文章主题。 2．根据第一段短语“floating in space”语境为在太空里漂浮、失重飞行，floating此处和flying含义相近；surviving (生存)、working (工作)、racing (竞速)均不符合太空场景。 3．根据第三段“The spaceship, called CYZI, can carry 6 people.”，CYZI飞船可搭载6人。 4．根据第四段“Some of the passengers include Scientist Li Licheng”，可知Li Licheng是一名科学家。 5．全文围绕中国商业太空旅行展开，介绍飞船、购票、政策扶持、多家航天企业布局，整体展示中国航天产业的发展与进步，其余选项仅为文中局部细节，并非写作核心目的。 （2026·江苏扬州·中考真题）What if things in your home—your toothbrush, books, desks, even you!—suddenly seemed weightless and began to float? This is what astronauts experience in a space station—microgravity (微重力). Even though the space station and the astronauts inside are in space, Earth’s gravity is still pulling on them, though very weak. Let’s explore the astronauts’ life in space. Though there are some challenges, life in space is a super-fun. Eating and sleeping Need to get from one place to another? Just push off a surface and glide there! Nothing stays put.

When they have free time, astronauts kick back by reading books and looking down at Earth. 1．According to the text, what may cause danger to the space station? A．Water in special bags. B．Very tiny food pieces. C．Specially prepared meals. D．Sleeping bags tied to the wall. 2．Which of the following should go in the empty box? A．Exercising for a strong heart. B．Moving freely. C．Dealing with space loneliness. D．Staying strong. 3．What does the text mainly talk about? A．Strange changes to astronauts’ bodies in space. B．Astronauts’ fun and challenging life in space. C．How astronauts do experiments in space environments. D．Why astronauts inside the space station can’t stay put. 【答案】1．B 2．D 3．B 本文是一篇说明文，介绍了宇航员在空间站微重力环境下的生活，包括饮食、睡眠、运动和娱乐等方面的挑战与乐趣。 1．第三段提到“Food crumbs can become a disaster if they get into equipment.”，食物碎屑可能对空间站造成危险。 2．第四段提到“Every astronaut has to exercise for about two hours a day...”，本段讲太空微重力会让骨骼、肌肉、心脏变虚弱，宇航员每天必须锻炼两小时维持身体强健，因此空框处应填“Staying strong”。 3．全文围绕宇航员在太空中的生活展开，介绍了饮食、睡眠、运动和工作等方面的内容，因此主旨是宇航员在太空中有趣而充满挑战的生活。 ( 1 / 6 ) 学科网（北京）股份有限公司 $
