六、阅读理解
Fish babies in space? In a space study on zebrafish(斑马鱼), Chinese scientists set 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 ⅩⅧ spaceship on April
25, and then they 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
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 backs. The low gravity (重力) in space is a big reason. On earth,
3gravity pulls everything to the 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% 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?
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.
2.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 backs.
D.The zebrafish swam in different directions.
4.What does the underlined word “waste” in paragraph 3 mean?
A.饵料 B.食物 C.排泄物 D.残渣
5.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.

六、【主旨大意】本文介绍了中国在太空进行的一项关于斑马鱼的研究。
1.A 细节理解题。根据“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项。
2.B 推理判断题。根据“In their special closed water world, the plants made air for the
fish and the fish’s waste gave the plants food.”可知, 鱼的排泄物为植物提供食物, 在B项
中,鱼指向植物的箭头表示鱼的排泄物为植物提供养分。故选B项。
3.C 细节理解题。根据“The scientists also found that the zebrafish acted differently ...
they often swam on their backs. The low gravity in space is a big reason.”可知, 太空低重力
导致斑马鱼经常仰着游。故选C项。
4.C 词义猜测题。由原文可知, 这种waste可作为植物的养分, 由此可推知, waste是指
斑马鱼的“排泄物, 粪便”, 故选C项。
5.C 主旨大意题。根据“Humans and zebrafish share 70% of the same genes. 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, 能对科学家更好地理解人类健康有帮助, 强调的是太空研究的意义。故选C项。
