In order to study deep space and explore the mysteries of the universe, Chinese scientists have developed advanced space probes. The Shenzhou series spacecrafts, which are designed to carry astronauts to the space station, have completed numerous successful missions. Astronauts need to undergo rigorous training to adapt to the harsh environment in space. They carry out scientific experiments in space to help humans better understand the universe. The Tianwen-1 probe was launched to explore Mars, and it successfully landed on the red planet, making China the second country to achieve this great feat. 1. 逐句标注不定式的成分与用法 ① Yang Liwei was the first Chinese person to go into space in 2003... ———不定式to go into space作定语 解析：修饰名词短语the first Chinese person，说明“进入太空的第一人”，不定式作定语常置于被修饰名词之后，此处与被修饰词为主动关系。 ② In order to study deep space and explore the mysteries of the universe, Chinese scientists have developed advanced space probes. ———不定式to study...and explore...作目的状语（in order to表目的） 解析：说明主句动作“研发先进太空探测器”的目的是“研究深空、探索宇宙奥秘”，in order to引导的目的状语可置于句首或句末。 ③ The Shenzhou series spacecrafts, which are designed to carry astronauts to the space station, have completed numerous successful missions. ———不定式to carry astronauts to the space station作定语 解析：修饰先行词The Shenzhou series spacecrafts，补充说明飞船的功能是“将宇航员送往空间站”，此处为被动含义（被设计用于承载），不定式作定语与被修饰词为动宾关系。 ④ Astronauts need to undergo rigorous training to adapt to the harsh environment in space. ———不定式to undergo rigorous training作宾语（need to do固定搭配）；不定式to adapt to...作目的状语 解析：第一个不定式作need的宾语，符合“need+to do”固定用法；第二个不定式说明“接受严格训练”的目的是“适应太空恶劣环境”。 ⑤ They carry out scientific experiments in space to help humans better understand the universe. ———不定式to help...作目的状语 解析：表主句动作“开展科学实验”的目的是“帮助人类更好地了解宇宙”，此处不定式前无介词，直接置于句末表目的。 ⑥ ...making China the second country to achieve this great feat. ———不定式to achieve this great feat作定语 解析：修饰名词the second country，说明“实现这一伟大壮举的第二个国家”，序数词后常接不定式作定语。 2. 核心词汇与固定搭配总结 ① 核心词汇：exploration（n. 探索）、astronaut（n. 宇航员）、mission（n. 任务）、probe（n. 探测器）、universe（n. 宇宙）、milestone（n. 里程碑）、rigorous（adj. 严格的）、harsh（adj. 恶劣的）、manned（adj. 载 ... ...
