五、(2025·盐城亭湖期末)阅读理解。
Fish babies in space? In a space study on zebrafish, Chinese had a new record. They 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 and they then lived in a closed fish tank with some plants. The fish grew up and had babies in 43 days.
In their special closed water world, the plants made air for the fish and the fish's waste(排泄物) gave the plants food. The scientists gave the fish food through a special needle(针管). Such a closed-loop ecosystem(封闭生态系统) is important for future study 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 than on Earth. For example, they often swam on their back. The low gravity(重力) in space is a big reason. On Earth, gravity pulls everything to Earth's center, and animals can find their way easily. Gravity also makes their bodies work harder and become stronger. Humans and zebrafish share 70% of the same genes(基因). So the new finding will help scientists better understand human health.
(
A. It took place in a closed water world.
B. The zebrafish gave birth to four babies at last.
C. It took zebrafish less than one month to grow up.
D. Scientists from different countries did it together.

A. Human bodies got stronger.
B. Animals could easily find way.
C. The zebrafish swam on their back.
D. The zebrafish swam in different directions.

A. The plan of the space study.
