One after another, telecommunications giants (通信巨头) have announced their latest fifth generation (5G) products. They have also claimed that 5G technology would be used on a massive scale by 2020. Yet, when reporting about 5G, many domestic media outlets have described it as a “much faster” technology than 4G without mentioning any of its other advantages. As a result, the common public view about 5G is that they could “download a high-density movie within one second”. Beyond that, most people know nothing about 5G.
Actually, 5G technology has many more advantages than 4G apart from speed. According to the criteria of 3GPP, an international standardization organization, 5G technology can be used for at least three purposes—for connecting everything, reliability of connections, and eliminating delays.
“Connecting everything” is an appropriate slogan for 5G technology, without which the Internet of things would be impossible. 5G would enable one server to connect to multiple terminals (终端) and thus establish high-speed coordination among them, and help the chips inside the terminals to timely react to meet people’s needs. Take for example, autonomous vehicles, which are mature technology products. Self-driving cars combine a variety of sensors, such as radar, computer vision, and GPS to identify navigation paths and obstacles. 5G technology will link all the elements of a transportation system, such as traffic lights, cameras and, of course, cars to establish perfect coordination so they can avoid obstacles and move on navigation paths, which will help strengthen self-driving technology.
Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required. For instance, in certain surgeries, surgeons insert nano-robots inside a patient’s body and have to maintain constant control over the robots to ensure they perform their functions and do not cause any harm to the patient. This is an technology can be of great help, as it can establish reliable and continuous connections between the monitor and the nano-robots.

On March 25, 2010, Kate and David Ogg heard the words every parent fears: Their newborn son wasn’t going to make it. Their twins—a girl and a boy—were born two minutes apart and 14 weeks premature, weighing just over two pounds each. Doctors had tried to save the boy for 20 minutes but saw no improvement. His heartbeat was nearly gone, and he’d stopped breathing. The baby had just moments to live.
“I saw him gasp (喘气), but the doctor said it was no use,” Kate said. “I know it sounds stupid, but if he was still gasping, that was a sign of life. I wasn’t going to give up easily.”
Still, the Sydney couple knew this was likely goodbye. In an effort to treasure her last minutes with the tiny boy, Kate asked to hold him.
“I wanted to meet him, and for him to know us,” Kate told Today. “We’d resigned ourselves to the fact that we were going to lose him, and we were just trying to make the most of those last, precious moments.”
Kate unwrapped the boy, whom the couple had already named Jamie, from his hospital blanket and ordered David to take his shirt off and join them in bed. The first-time parents wanted their son to be as warm as possible and hoped the skin-to- skin contact would improve his condition. They also talked to him.
"We were trying to attract him to stay.” Kate said. “We explained his name and that he had a twin that he had to look out for and how hard we had tried to have him.”
Then something miraculous happened. Jamie gasped again—and then he started breathing. Finally, he reached for his father’s finger. The couple’s lost boy had made it.

Dear Ms Smith,
I’m writing to ask whether you could do me favor. I’ve just finished an essay naming “Differences between traditional Chinese and Western festivals”, so I’m not sure whether it is well written. To be honestly, I’m not that familiar with some traditional Western festivals. That’s because I’m turning to you for help. I’d appreciate it if you could spare some time to look into my essay for possible mistakes and polish them. Also, I’m looking forward to your valuable advices. My essay has been sending to you along with this email. I hope it won’t cause you too much more trouble.
Thank you in advance.
