9 . A snowboarder was feeling lucky to be alive yesterday after a helicopter rescue(直升机营救).
Ben Akintola, 30, was snowboarding in the French Alps under a clear blue sky in the afternoon when a large amount of snow fell down the side of the mountain. He didn’t have time to escape(逃脱) and it hit him with full force and knocked him senseless.
He woke in the night in total darkness. He was lying on an icy rock. Amazingly, he still had a mobile phone signal(信号), so he called a friend a thousand kilometers away in Britain. His friend called the French rescue services.
“I was waiting for what seemed like hours on that rock. I was beginning to give up hope when I heard the sound of a helicopter. It was circling around in the darkness, looking for me. I was trying my best to wave my mobile around. Fortunately the helicopter pilot saw the light.”
“I was overjoyed when the helicopter headed my way. It stayed above me and began lowering a rope.”
Ben was in hospital last night but he was not being treated for any serious injuries. He’s looking forward to going home today.
The French rescue services said: “We were very pleased that we were able to save Ben. The risk of snow slide off-piste(非滑雪场地的) is much higher at this time of year. All snowboarders and skiers should stay on the ski runs and not go off-piste. Ben was very lucky.”

10 . There have been a lot of comments recently surrounding 5G, the next generation of wireless technology.
5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity (容量).
However, technology experts say there is a major way that 5G is different from the earlier systems.
5G will help fuel future “smart cities” by connecting sensor networks. 5G is also expected to connect self-driving cars and support new technologies involving virtual reality (虚拟现实). Higher 5G speeds could also permit doctors to commonly perform remote medical operations. Factories and businesses could use 5G technology to increase automation and improve the collection of information.
| A．Why is 5G so popular |
| B．What is this technology |
| C．Every coin has two sides |
| D．The new 5G system promises more of the same |
| E．It will move beyond mobile network technology |
| F．A breakdown of 5G networks may cause economic losses |
| G．A failure during a doctor's remote operation could lead to death |
