1. D 根据“Have you ever dreamed of becoming an astronaut?”并结合备选项可知，此处应是引出下文，应表示怎样成为宇航员，因此 D 项“中国宇航员是怎么做到的呢？”符合语境。故选 D。
易错警示 忽略上下文逻辑
上文提到“Have you ever dreamed of becoming an astronaut?”，这是一个关于成为宇航员的梦想的问题。下文开始解释成为宇航员的条件，因此这里需要一个过渡句，引出如何成为宇航员的主题。可能会错选 C. Health is important.，但 C 句更适合放在具体解释健康要求之前，而不是作为过渡句。
2. C 根据“To be an astronaut, you need to be healthy.”并结合备选项可知，此处应表示健康方面，因此 C 项“健康很重要。”符合语境。故选 C。
3. B 根据“Become stronger with hard training.”与“You will wear a 200-kilogram suit and do tasks underwater for 6 or 7 hours without eating or going to the toilet.”并结合备选项可知，此处应指训练方面，因此 B 项“当你成为一名后备宇航员时，你将开始训练。”符合语境。故选 B。
4. A 根据“Learn science.”以及“Astronauts complete over 60 courses to get ready for a mission, including Maths, English, spaceship design, physics and many more.”并结合备选项可知，此处应说明宇航员的学习方面，因此 A 项“他们还可以在太空中做科学实验。”符合语境。故选 A。
5. E 根据“Even if you qualify as a backup astronaut”并结合备选项可知，此处表示转折，应表示“即使你有资格成为一名后备宇航员，也有可能去不了太空”，因此 E 项“你有可能永远去不了太空”符合语境。故选 E。
