新素材 太空养鱼 Fish babies in space! In a space study on zebrafish, Chinese scientists have set a new record. They successfully made four zebrafish live and grow in
a
closed water world.The zebrafish first
went
（go）to China's space station on the Shenzhou-18 spaceship on April 25, 2024. The four fish grew up and had their babies in a closed fish tank with some plants in 43 days. And one year later, another six zebrafish were sent into space on Shenzhou-20 on April 24.So
how
did the special closed environment work? In fact, the plants made air for the fish and the fish's waste（排泄物）gave the plants food. The scientists used a special needle（针管）to feed
（feed）the fish.Such a closed-loop ecosystem（封闭生态系统）is important for future studies in space. It means that plants and animals can live in space more
simply
（simple）.The scientists also found that the zebrafish's behaviour（行为）in space was different
from
that on Earth. They often swam on their backs. That's because
the low gravity（重力）in space made it possible. On Earth, gravity pulls everything to Earth's centre, and animals can find their way easily. Gravity also makes their bodies work harder
（hard）and become stronger. Considering that humans
（human）and zebrafish share 70% of the same genes（基因）, the new finding will allow scientists to understand
（understand）human health better.1.

解析：
【解析】
1. 空格后是可数名词单数world，此处表示“一个封闭的水环境”，closed以辅音音素开头，填不定冠词a。
2. 根据时间状语on April 25, 2024可知句子为一般过去时，go的过去式是went。
3. 后文介绍了封闭环境的运行原理，此处是询问“这个特殊的封闭环境是如何运作的”，填疑问词how。
4. 此处是固定结构use sth. to do sth.，表示“用某物做某事”，填不定式to feed。
5. 此处修饰动词live，需用副词形式，simple的副词是simply。
6. 此处是固定搭配be different from，表示“与……不同”，填介词from。
7. 前文提到斑马鱼在太空仰泳的现象，后文是解释该现象的原因，填because。
8. 根据后文的stronger可知此处暗含比较含义，表示重力让身体更努力运作、变得更强壮，hard的比较级是harder。
9. 此处表示泛指人类，用human的复数形式humans。
10. 此处是固定结构allow sb. to do sth.，表示“允许某人做某事”，填不定式to understand。
