新素材 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. 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 in space. For example, they often swam on their back. The low gravity(重力) in space is a big reason. On the earth, gravity pulls everything to the earth's center, and animals can find their way easily. Gravity also makes their bodies work harder and become stronger.
Humans and zebrafish share more than 70% of the same genes(基因). So the new finding will help scientists better understand human health.
1. What do we know about the space study on zebrafish?
A. It took place in a closed water world.
B. The zebrafish gave birth to four babies at first.
C. It took zebrafish less than one month to grow up.
D. Scientists from different countries did it together.
2. 新考法·图文转换题 Which picture should be in the circle to show the ecosystem in the fish tank?
3. What was the result of the low gravity in space?
A. Human bodies got stronger.
B. Animals could easily find their way.
C. The zebrafish swam on their back.
D. The zebrafish swam in different directions.
4. What is the last paragraph mainly about?
A. The plan of the space study.
B. The course of the space study.
C. The meaning of the space study.
D. The finding of the space study.

答案
【解题导语】本文介绍了中国在太空进行的一项关于斑马鱼的研究，包括研究的环境、斑马鱼在太空的生存繁衍情况、太空低重力对斑马鱼的影响以及该研究对理解人类健康的意义。
1 A 细节理解题。根据第一段中的“They successfully got four zebrafish to live and grow in a closed water world”可知，这项太空研究是在一个封闭的水环境中进行的。故选A。
2 B 图文转换题。根据第三段中的“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”可知，鱼的排泄物为植物提供食物。
3 C 细节理解题。根据第五段中的“The scientists also found that the zebrafish acted differently in space. For example, they often swam on their back. The low gravity(重力) in space is a big reason”可知，太空低重力导致斑马鱼经常仰着游。
4 C 段落大意题。根据最后一段“Humans and zebrafish share more than 70% of the same genes(基因). So the new finding will help scientists better understand human health”可知，因为斑马鱼和人类基因相似，所以这个新发现有助于科学家更好地理解人类健康，故该段强调的是该项太空研究的意义。
