[2026 贵州黔东南州期末]On 24th April, 2025, China successfully launched the Shenzhou-20 spaceship from Jiuquan Satellite Launch Centre. Three astronauts—Chen Dong, Chen Zhongrui, and Wang Jie—flew to China’s space station aboard the Long March-2F rocket. They would live and work in space for about half a year as planned, doing important jobs like science tests, spacewalks, and checking new machines. The team would come back to Earth around October. This launch day was special because it was China’s 10th Space Day, celebrating the country’s first satellite Dongfanghong-1 sent to space on the same date in 1970.
The Long March-2F rocket has been upgraded 32 times since its first flight in 1999. Its new digital system（数字系统）works much faster now. Earlier, flight information was saved in a “black box” and checked after landing. But today, it sends updates to scientists every second—as fast as copying 100 pages of paper per second. This helps experts monitor（监测）the rocket’s journey from Earth. With China’s space station now running smoothly, this rocket will launch twice yearly using smarter digital systems.
During their mission, the astronauts would do over 20 experiments to see how weightlessness affects humans. They would study small animals like the zebra fish to learn how living things regrow body parts in space. This first-ever Chinese experiment in space might teach us how to slow aging or cure diseases on Earth. Nearly 60 other tests about space biology and new technology were planned too. The Shenzhou-20 mission marks another big step in China’s space exploration journey.

16—19 B C A B
16. B 细节理解题。根据 They would live and work in space for about half a year as planned 可知,神舟二十号的航天员按计划将在太空停留约半年,即约6个月。故选B项。
17. C 细节理解题。根据“This launch day was special because ... the country's first satellite Dongfanghong-1 sent to space on the same date in 1970. ”可知,4月24日特殊是因为这一天是中国第一颗人造卫星“东方红一号”发射的日子。故选C项。
18. A 推理判断题。根据“Earlier, flight information was saved ... But today, it sends updates to scientists every second... ”可知,作者通过对比长征二号F运载火箭过去与现在的数据系统工作方式,来体现其新数据系统速度更快。故选A项。
19. B 推理判断题。根据“This first-ever Chinese experiment in space might teach us how to slow aging or cure diseases on Earth. ”可知,太空实验可能会为地球上的人们提供减缓衰老或治疗疾病的方法,由此可推断其是有意义的。故选B项。
