1 . 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.”

2 . 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 |
3 . Each year there are at least five million people around the world who develop serious flu (流感), and almost half a million deaths. When someone we know gets the flu virus, we expect them to be very careful not to pass it on to others. Doctors and nurses working with flu patients also need to protect themselves from the virus. But what is the best way to do this? This is the question that flu expert Professor Jonathan
Van-Tam at Nottingham University is trying to answer. He wants to find out how flu is transmitted, so that he can stop doctors and nurses getting sick.
Van-Tam explains their method, "There are 41 volunteers in my experiment. Some healthy volunteers are made to get flu first. When they show symptoms (症状 ) , other volunteers, usually called recipients(接受者), enter the house. Everyone lives together in the small space for four days. Some of the recipients wear face masks, and wash their hands every 15 minutes, but some have no protection. In this way we can study who catches the flu and which ways of transmitting flu are important. During the four days when they are in contact with the virus, and for the ten days after that, the flu recipients are checked regularly."
The experiment is not simple and it is very expensive. It is difficult to design correctly, and it is also difficult to plan and carry out. Just one study like this takes about 18 months to organize and needs hundreds of people working on it. But Van-Tam believes it is worth because the results will help to decide what type of protection is needed for people working in hospitals with large numbers of flu patients around the world. And perhaps it could reduce the number of deaths from flu each year.
