Fish babies in space? What surprising news! In a space study on zebra fish, Chinese scientists have set a new record. They successfully got four zebra fish to live and grow healthily in a closed water world.
The zebra fish went to China's space station on the Shenzhou ⅩⅧ spaceship on 25th April, 2024. After that, they lived in a closed fish tank（缸）with some plants. The fish grew up and had babies in 43 days. It means that the fish completed a whole life stage, from growth to development and giving babies.
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 special needle（针头）.
Such a closed environment is important for future studies in space. It means that plants and animals can live in space more easily.
The scientists also found the zebra fish acted differently in space. For example, they often swam on their backs in space. The low gravity（重力）in space is a big reason. However, on Earth, gravity pulls everything to the Earth's centre, and animals can find their way easily. Gravity also makes their bodies work harder and become stronger.
It isn't the first time fish have been sent into space. Zebra fish were earlier sent to the space station in 1976. Why do scientists choose zebra fish? Humans and zebra fish share 70 per cent of the same genes（基因）. So the new finding will help scientists better understand human health and human diseases.
21. (
A. There were more than four zebra fish at last.
B. It took scientists less than one month to finish the study.
C. It took place in an open fish tank.
D. Scientists from different countries did it together.
22. (
23. (
A. Human bodies get stronger.
B. Animals can easily find their way.
C. The zebra fish often swim on their backs.
D. The zebra fish swim in the same direction.
24. (
A. The importance of the study.
B. The ways of the space study.
C. Further studies on zebra fish.
