The three astronauts of China’s Shenzhou 16 mission returned to Earth Oct 31, 2023 after completing a five-month mission aboard the country’s space station. Astronauts Jing Haipeng (the mission’s commander), Zhu Yangzhu and Gui Haichao 【小题1】 (touch) down in their Shenzhou 16 spacecraft return capsule at the Dongfeng landing site around 8:10 a.m., according to the China Manned Space Agency (CMSA). The Shenzhou 16 spacecraft separated 【小题2】 the Tiangong space station at 8:37 pm Monday on Monday, CMSA stated. Jing and company had 【小题3】 (early) handed over control of the space station to the Shenzhou 17 crew, who arrived on Oct. 26.

Zhu and Gui were the first 【小题4】 (member) of China’s third astronaut selection group to fly to space, with Gui also being the first payload specialist to fly to Tiangong. Mission highlights included Jing and Zhu conducting 【小题5】 eight-hour extravehicular activity, or spacewalk; cultivating vegetables; and a live, interactive lecture, which notably involved 【小题6】 (light) a match on the space station. Shenzhou 16 was the 【小题7】 (five) crewed mission to Tiangong and China’s eleventh astronaut flight overall. China aims to keep Tiangong operational and 【小题8】 (permanent) occupied for at least a decade. The nation also plans to expand the T-shaped space station, 【小题9】 currently consists of three modules and is about 20% as massive as the 【小题10】 (internation) space station.

The world's first 5G-enabled railway station is 【小题1】 its way! China Mobile Shanghai and tech giant Huawei jointly made 【小题2】 announcement on Monday that they will start the construction of 5G network in Shanghai Hongqiao Railway station, making the station the world's first to build upon a 5G system. It 【小题3】 (expect) to realize a deep indoor 5G coverage inside the station by the end of 2020 when travelers will be able to enjoy 【小题4】(variety) 5G network-based services. 【小题5】 (use) the super fast 5G WiFi, people can download a movie in less than 20   【小题6】 (second) in the crowded station.

A 5G network in the railway station will be part of the effort 【小题7】 (promote) the digital economy development in Shanghai. Just as Peter Zhou, chief marketing officer for Huawei Wireless Network Product Line, once 【小题8】(say), “The railway stations of the future may be more intelligent than we can 【小题9】 (possible) imagine.

While 4G changes our life, 5G will change the society,【小题10】 means using 5G technology to connect everything, such as robotics, cars, and so on. It will make the world fully digitalized and intelligent.

On May 18, it was announced that China 【小题1】 (achieve) success in drilling fire ice, a frozen mixture of water and natural gas, from the South China Sea. 【小题2】 (official) known as methane hydrates (甲烷水合物), fire ice produces a high amount of energy when it is burnt and its chemical reaction produces nothing but dioxide and water.

Fire ice, both clean and energy-intensive, 【小题3】 (consider) the fuel of the future. But, the Chinese team succeeded in 【小题4】 (extract) fire ice for nearly eight successive days, which is a big breakthrough. However, it is too early 【小题5】 (say) a new energy source has been found. The worlds total fire ice reserve is about 21,000 trillion cubic meters，【小题6】, if extracted, could meet the worlds energy need for 1,000 years. But the【小题7】 (success) test drilling of fire ice does not mean it can be extracted for 【小题8】 (industry) use. China has to solve many problems 【小题9】 it can use fire ice as a source of energy.

It’s thought that only by 2025 at 【小题10】 earliest might people be able to look at realistic commercial options.
