【文章导读】本文介绍了我国在太空中研究涡虫等动物，以探究太空环境对生命再生与健康的影响。研究成果将为保障航天员健康和支持未来太空探索提供重要帮助。
On 24 April, 2025, China launched(发射) Shenzhou-20 into space. It carried planarians(涡虫) into space for the first time.
Planarians are special because they can regrow their bodies when their bodies are cut. And this can happen again and again. This “superpower” makes them wonderful for scientific studies. Scientists will watch how planarians regrow in space. They want to see how space changes this ability.
Studying planarians has important meaning. Scientists hope to learn how space changes the way planarians regrow and how gravity(重力) affects their growth. All of these will finally help people understand more about body aging and regrowth of living things.
But that’s not all! China will do more studies on different ▲ in space. In April last year, China sent four zebrafish(斑马鱼) to the Tiangong space station. Studies on these zebrafish taught people much about how to keep astronauts healthy in space. Besides, Chinese scientists will study mice in space. That will help scientists better prepare for sending humans to the moon one day.
All these studies show the importance of space exploration. By studying these animals in space, scientists can discover new ways to help people live healthier lives.
()1. Why are planarians special for scientific studies?
A. Their bodies age slowly.
B. They can live without gravity.
C. Their bodies change easily in space.
D. They can regrow again after being cut.
()2. What does the third paragraph mainly talk about?
A. The ways to do scientific studies.
B. The future space programmes of China.
C. The meaning of studying planarians.
D. The reasons for using zebrafish in studies.
()3. Which of the following can be put in “▲”?
A. animals
B. plants
C. vegetables
D. fruits
()4. What did studies on zebrafish in space teach people?
A. How to feed fish well in space.
B. How to stop aging in space.
C. How to send humans to the moon.
D. How to keep astronauts healthy in space.
()5. How does the writer feel about China’s space studies on animals?
A. Relaxed.
B. Hopeful.
C. Worried.
D. Nervous.

解析
【分析】
本题为英语阅读理解题，围绕中国太空动物研究展开，涵盖细节理解、主旨大意、推理判断三类题型。解题思路：先通读全文把握核心主旨，再针对每道题的题型，定位原文对应关键信息，逐一分析选项排除错误答案，最终选出符合原文的正确选项。
【解析】
1. 第1题（细节理解题）：根据文章第三段第一句“Planarians are special because they can regrow their bodies when their bodies are cut. And this can happen again and again.”可知，涡虫的特殊之处在于被切割后可反复再生身体，对应选项D。
2. 第2题（主旨大意题）：第三段首句“Studying planarians has important meaning.”为主题句，后文围绕研究涡虫的重要意义展开，对应选项C。
3. 第3题（推理判断题）：空格后提到“sent four zebrafish（斑马鱼）”“study mice（老鼠）”，斑马鱼和老鼠均属于动物，因此空格处应填animals，对应选项A。
4. 第4题（细节理解题）：根据第四段“Studies on these zebrafish taught people much about how to keep astronauts healthy in space.”可知，太空斑马鱼研究教会人们如何在太空中保持宇航员健康，对应选项D。
5. 第5题（推理判断题）：文章最后一段指出太空动物研究能帮助人们找到更健康的生活方式，体现作者对该研究持充满希望的态度，对应选项B。
