From all aspects, it is fair     1     (say) that the Shenzhou XIII mission has been a (n)     2     (succeed). In terms of speed, it set a new record. The Shenzhou XII return capsule spent over 24 hours revolving around (绕……旋转) Earth 11 times before returning on Sept 17, 2021. This time the Shenzhou XIII reentry module (返回舱)     3     (dramatic) shortened the orbiting time to about nine hours, going around Earth five times.

The search and rescue team on Earth also demonstrated its     4     (power) capabilities. The Dongfeng Landing Site has a search zone of tens of thousands of square kilometers, which     5     (contain) desert, salt flats, as well as wetlands that make it challenging to find out     6     the reentry module might land. Yet the team finished the job of finding the three astronauts hours earlier     7     expected.

Besides, the return of the crew also signaled that the Chinese space station had finished     8     (confirm) its key technologies. Since 2021, five flight     9     (mission) have been launched. The sixth has now been completed, and has confirmed that the space station can meet all the required standards for operation.

2022 is a key year. Two experimental modules, two manned spaceships carrying six astronauts, and two cargo (货物) spaceships will take     10     this year, pushing the construction process of China’s space station further forward.

Sora, a new AI model developed by OpenAI — creator of chatbot ChatGPT —     1     (become) a global sensation (轰动) since its being launched. Sora can generate high-quality video clips based on given text prompts, in     2     (compare) with ChatGPT, which is only text-to-text.

The model understands     3     the user has asked for in the prompt and how those things exist in the physical world.

Liu Xingliang, director of the Data Center of China Internet, said Sora is     4     (undoubted) a major breakthrough for AI. “It demonstrates AI’s     5     (advance) ability to understand and create complex visual content and brings about unprecedented opportunities and challenges for content creation, entertainment and film and television production industries. The video-generation model will help creators turn their ideas     6     reality at a faster speed and at a lower cost,” Liu said,     7     (add) that AI is expected to play a more important role in the future.

Still, it does not necessarily mean the end of traditional industries, and more effort is needed     8     (explore) new artistic forms and expression methods by integrating AI technology. Meanwhile, experts say using text-to-video AI models raises a lot of     9     (concern) about ethics, copyright protection, personal privacy leakage and data security. Ensuring the authenticity and transparency of the content has become     10     important issue, and we need to set up rules to ensure the healthy development of such technology.

As awareness of the human impact on the environment     1     (increase), people are becoming more willing than ever before, to accept clean lifestyles. But some people aren’t totally sure where to begin. While large steps require planning, smaller steps can    2     (take) right away.
