6G is     1     sixth generation of wireless technology. A 6G network follows up 4G and 5G,     2     (use) higher frequency bands and cloud-based technology to deliver record-breaking speeds.

6G takes technology originally meant for mobile phones and applies it     3     a much wider set of uses, including transportation, healthcare and smart-home networks. Distant oceanic farming and autonomous driving are potential areas     4     6G technology can be adopted.

Technically, 6G doesn’t exist yet,     5     the race for 6G is on. As an     6     (extreme) important national strategy, 6G has been at the core of China’s efforts for technological breakthroughs, given its wide industry applications.

The     7     (construct) of China’s 5G network is advancing steadily, and the network coverage capability continues to improve. The number of 5G base stations     8     (reach) 2.312 million last year, accounting for more than 60 percent of the world. The solid foundation of 5G applications makes     9     possible for China to continue to lead in the development of the next-generation technology standards for broadband networks.

It is said that China will develop a clear 6G vision this year and start its standardization by 2025. The development of other pioneering     10     (field) such as humanoid robots, the metaverse and quantum (量子) technology will also be accelerated.

China plans to expand its space station to six modules(舱)from three in coming years, a researcher at the China Academy of Space Technology said on Wednesday.

The space station will play     1     important role as “space home port”,     2     (provide) an alternative platform for near-Earth missions as the International Space Station (ISS) nears the end of its lifespan(寿命). The ISS     3     (expect) to be decommissioned (退役) after 2030. The lifetime of the Chinese space station will be more than 15 years. It is longer than the 10 years the country     4     (previous) announced.

China’s self-built space station, also     5     (know) as Tiangong, or Sky Palace in Chinese, has been     6     full operation since late 2022. And it hosts a maximum of three astronaut s at an orbital altitude of up to 450 kilometers.

It will have a weight of 180 tonnes after expansion, about 40 percent of the mass of the ISS,     7     has been in orbit for over two decades.

Regarding the expansion, another module is also in the plan. Other plans, including the development of large space telescopes, 3D printers, intelligent robots     8     a warning system, are also underway.

Chinese state media said last year that China would be matchless as the ISS was approaching     9     (retire), and added that China had been requested by several countries     10     (send) their astronauts to the Chinese station.

On December 9^th, Chinese astronauts, Zhai Zhigang, Wang Yaping, and Ye Guangfu,     1    (conduct) the science lecture 400 kilometers above Earth, as they orbited in the Tiangong space station.

They showed viewers     2     they lived and worked inside the space station. In response to     3     Hong Kong student’ s question about water, Wang said the water they drank was recycled, noting that there was no difference in taste between regular and     4    (recycle ) water. “With a water recycling system, every drop of water     5    (make) full use of” she said.

Wang said the astronauts might look     6    (fat) than they were on earth as the microgravity in space can affect blood circulation. Zhai introduced the     7    (special) designed uniform Ye was wearing during the class. According to Zhai, it is called a “penguin jumpsuit” and it has multiple elastic bands inside to help the astronauts maintain their muscle     8    (strong).

Ye demonstrated experiments related to cell growth in the weightless environment in space, during     9     he compared the growth and shape of cells in artificial gravity and zero-gravity so as     10    (study) their changing rules and mechanisms.
