2026年中考时文阅读之神舟二十一号太空小鼠后代健康成长专题英语练习（含答案）

神舟二十一号太空小鼠后代健康成长专题英语练习 话题介绍 神舟二十一号任务中，中国科学家首次将实验小鼠送入太空进行长期生物学研究。令人振奋的是，这些太空小鼠返回地球后成功繁衍后代，且后代小鼠健康成长，这一突破性成果为人类深空探索和太空生命科学研究提供了重要数据。这项研究不仅证明了哺乳动物在太空环境下的生殖能力，也为未来人类在太空长期居住的可能性提供了科学依据。 一、阅读理解（共5小题，每小题2分，满分10分） Passage A In November 2024, China's Shenzhou-21 spacecraft carried a special group of passengers - 12 laboratory mice. This was the first time that live mammals had been sent into space for such a long duration on a Chinese mission. The mice spent 30 days aboard the Tiangong space station, where they were closely monitored by scientists on Earth. The main purpose of this experiment was to study the effects of microgravity on mammalian reproduction and development. After returning to Earth, the mice were carefully examined and then allowed to breed. To everyone's amazement, all the female mice successfully gave birth to healthy offspring. These "space babies" have been growing normally, showing no significant differences from mice born under normal conditions. This groundbreaking research has important implications for future space exploration. It suggests that mammals, including humans, might be able to reproduce in space environments. The data collected from this experiment will help scientists develop better strategies for long-term space missions, such as those to Mars or beyond. Questions: How many laboratory mice were sent into space on Shenzhou-21 A. 6 B. 8 C. 10 D. 12 Where did the mice stay during their space mission A. Shenzhou spacecraft B. Tiangong space station C. International Space Station D. Lunar module What was the main purpose of sending mice into space A. To test spacecraft safety B. To study mammalian reproduction in microgravity C. To find new animal species D. To prepare for space tourism How long did the mice stay in space A. 15 days B. 20 days C. 25 days D. 30 days What does this research suggest about future space exploration A. Space travel will become cheaper B. Humans might be able to reproduce in space C. Mars missions will be cancelled D. Space stations will be larger 重点短语和句式解释： laboratory mice (实验小鼠) microgravity (微重力) groundbreaking research (突破性研究) long-term space missions (长期太空任务) "This groundbreaking research has important implications..."
