五、閱讀理解
Shenzhou 14’s return capsule (太空艙) landed successfully at the Dongfeng landing site at 8：09 p．m on Dec. 4th. Chinese astronauts onboard the Shenzhou 14 spacecraft have returned with the world’s first rice seeds (種子) produced in space. They were in space for 183 days. During that time, they watched and directed the finish of China’s Tiangong space station and several life science experiments. While there have been other rice experiments in space, the goal of the experiment made on Tiangong is to produce the complete life cycle of the plant. Because it begins with a seed and ends with a fully grown and developed plant which produces new seeds. The experiment began on July 29, and after 120 days in space, they successfully produced new seeds.
Since the 1980s, China has been taking rice seeds and other crops to space to help them mutate (變異) and produce more rice once they were planted on Earth. But growing rice in space is a difficult challenge because of the worst conditions of space, such as microgravity (微重力) and so on.
The new seeds have been passed to many national technology and science centers in Beijing. They will also be sent to labs in Shanghai for further study.

6．D　解析：本題考查固定用法。句意：——多棒的飛機模型??！——多謝夸獎。我自己用3D打印機做的。by oneself為固定用法，意為“自行，獨自”。故選D。
7．C　解析：本題考查固定句型。句意：直到晚上11點他才完成作業。not...until...直到……才……，故選C。
