In January, cameras were on hand to film the jaw-dropping sight of the world’s first 5G remote surgery on a lab animal. It was a human’s turn on March 16, 【小题1】 a doctor in the Chinese city of Sanya put a device into the brain of a patient nearly 1,900 miles away in Beijing. At this point, you would 【小题2】(forgive) for thinking you were watching a sci-fi film set sometime in 【小题3】 future, but this is actually present-day surgery, thanks to 5G technology.

Until now, remote surgery 【小题4】(use) wireless networks has been impossible, because the time lag (间隔) between input and output lasts around a quarter of a second, sometimes as long as 2 seconds—a delay potentially 【小题5】(harm), possibly deadly, to a patient. Now, 5G promises 【小题6】(change) all that, with its time lag 【小题7】 (reduce) to 2 milliseconds between devices. The speed ensures surgeons can operate at a much greater distance 【小题8】the operating room.

The technology will apply to both “tele-presence,” where a surgeon can 【小题9】 (mere) follow an operation on a video connection and offer expert support, and “tele-surgery,” where he or she actually 【小题10】       (operate) the surgical device from far away. Such technology has the potential to transform the wider surgical industry, with huge benefits for patients.

Nearly two decades【小题1】 (pass) since China sent the first Beidou satellite into space in 2000. During that time, more Beidou satellites were sent into orbit (轨道), 【小题2】 (form) the Beidou Navigation Satellite System (BDS). In late 2012, it began providing positioning, navigation, timing and messaging 【小题3】 (service) to people in China and other parts of the Asia-Pacific region. At the end of 2018, BDS started to serve users worldwide. Now with two more Beidou satellites 【小题4】 (launch) on Dec 16, 2019, BDS has 53 satellites in orbit.

China launched the Shenzhou-17 manned spaceship from the Jiuquan Satellite Launch Center in northwest China on Thursday, 26^th October, 2023.

A Long March-2F carrier rocket, carrying the Shenzhou-17 spacecraft with three Chinese astronauts, 【小题1】 (know) as taikonauts, on board, blasted off at 11:14 a.m. Beijing Time. About 10 minutes after the launch, the spaceship separated 【小题2】 the rocket and entered its pre-determined orbit with the crew in good condition, 【小题3】 (mark) the launch as a complete success, announced the China Manned Space Agency (CMSA). This is 【小题4】 30th flight mission of China’s manned space program, all of 【小题5】 are successful, and the 12th manned mission of the program. The Shenzhou-17 crew, with Tang Hongbo as the commander and Tang Shengjie and Jiang Xinlin as the 【小题6】 (operator), is scheduled to stay in orbit for about six months. The trio is known as the country’s 【小题7】 (young) lineup by average age-with Commander Tang at 48, Operator Tang at 34, and Jiang at 35, since the space station’s 【小题8】 (construct) began.

The Shenzhou-17 crew 【小题9】 (undertake) a series of tasks, and continue to evaluate the 【小题10】 (function) performance of the space station assembly.
