Ⅰ.阅读理解【主题：人与自然　太空探索】
　　Have you ever seen fish babies in space In a space study on zebrafish, Chinese scientists successfully got four zebrafish to live and grow in a closed water world.
　　The zebrafish went to China's space station on the Shenzhou-18 spaceship on April 25, 2024. Since then, they have been living in a closed fish tank (罐) with some plants. In their special closed environment, the plants made air for the fish and the fish's waste gave the plants food. The scientists gave the fish food through a piece of special equipment. The fish grew up and had babies in 43 days.
　　Such a closed-loop ecosystem (闭环的生态系统) is important for future studies in space. It means that plants and animals can live in space more simply and easily.
　　The scientists also found that the zebrafish acted differently from how they did on Earth. For example, they often swam on their backs. The low gravity in space is a big reason. On Earth, gravity pulls everything to Earth's centre, and animals can find their way easily. Gravity also makes their bodies work harder and become stronger.
　　Humans and zebrafish share 70 percent of the same genes. So the new finding will help scientists better understand human health.
1．What is paragraph 2 mainly about
A．The Shenzhou-18 spaceship's design.
B．The role of plants in space studies.
C．Zebrafish's life in space station.
D．The importance of closed-loop ecosystems.
2．What made air for the fish in the closed environment
A．The plants.
B．The special equipment.
C．The fish's waste.
D．The water in the open air.
3．(新考向　图片理解题)Which picture shows how zebrafish swam in space
A． B．
C． D．
4．Why is the zebrafish study important
A．It improves spaceship technology.
B．It helps understand human health.
C．It shows fish can have babies in space.
D．It keeps the costs of the space station low.
Ⅱ.阅读表达【主题：人与自然　太空探索】
　　阅读下面短文，简略回答问题。
　　What would it be like to live on Mars The movie The Martian has given us some answers. It follows an astronaut named Mark who is left on Mars for nearly two years. In order to live on Mars, Mark finds a way to grow potatoes in a special room. He wears a spacesuit when he is outside his “home”. However, Mark has to face many difficulties, such as dust storms.
　　In fact, just like in the movie, walking on the surface of Mars without a suit is a bad idea. Your skin would be peeled away like pieces of burning paper; your blood would turn to steam (水蒸气) and you would die within half a minute. There is bad radiation (辐射) and dust storms. So people would most likely live in underground homes. If technology improves, more people and construction (建筑) materials may be sent to Mars. Only then could people build houses on the surface. And life would start to look like that on Earth. On Mars, people could grow crops, such as wheat and potatoes, in special boxes. They could help make oxygen for humans to breathe like trees do on Earth. But it won't be an easy thing.
　　How can people move around Mars People have suggested cars, bikes, trains, cable cars and planes. However, there are no official plans saying exactly what humans will use.
1．What does Mark do to live on Mars

2．How long would a person live on Mars at most without a spacesuit

3．What is oxygen used for according to the passage

4．Where would people most likely live on Mars at first according to the passage

5．Which way of moving around Mars (such as cars, bikes, cable cars) do you like best Why

Ⅰ.【语篇解读】本文讲述了中国科学家在太空斑马鱼研究中的成果，发现斑马鱼能在闭环的生态系统中生存繁殖，且行为与地球不同，这对未来太空研究和人类健康理解有重要意义。
1．C　解析：段落大意题。根据第二段“The zebrafish went to China's space station on the Shenzhou-18 spaceship on April 25, 2024. Since then, they have been living in a closed fish tank (罐) with some plants...The fish grew up and had babies in 43 days.”可知，本段主要介绍了斑马鱼进入太空站后的生活情况，包括它们的生活环境、食物来源以及生长繁殖情况。故选C。
2．A　解析：细节理解题。根据第二段中的“In their special closed environment, the plants made air for the fish”可知，在封闭环境中，植物为鱼制造空气。故选A。
