1 . Whether from news reports or social media articles, you may know that 5G is coming. 5G is the 5th generation (代) network. It is a new network after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data (数据) speed. One can download a two-hour movie in less than 10 seconds, and it is making our lives more and more convenient.

5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet or place orders for food and drinks.

5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.

It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.

The facts listed above are only a part of what 5G will make possible and popular. Just as in the early days of the Internet in the 1990s, few could see how it could change or lie around the world. The same will surely be true of 5G. With 5G, many things do not seem like dreams any more. Now let’s get ready to say goodbye to 4G and welcome the coming of 5G.

3 . When visitors to the Palace Museum feel a need to sit down for a cup of tea or find a bathroom without a long line, they soon will be able to turn to their smart phones for the information they need.

Thanks to an agreement signed on Friday by the museum and Huawei, this modern solution will use 5G technology to build a “smart network”. Under the agreement, 5G Wi-Fi signals will cover the Palace Museum, China’s royal palace from 1420 to 1911.

“It’s important to always stay close to the latest technology to better serve the public,” said Shan Jixiang, former director of the Palace Museum. Shan said there is still much room for improvement in dealing with a large number of cultural relies(纪念物), such as when the priceless painting “Along the River During the Qingming Festival” is exhibited(展览) again in the future. When it was last exhibited in 2015, visitors stood in long lines until 3 am to have a look. The museum ended up preparing fast food to serve the hungry visitors. “I don’t want that situation to happen again,” Shan said. “Our work can be done in a more scientific way.”

The new system will also make use of the closed-cameras that are set up all over the Palace Museum to protect the museum’s valuable relics. More than 1.86 million of them are stored at the museum, which recorded nearly 20 million visits from the public last year. “How can we make sure no single visitor who might have bad ideas endangers these treasures?” Shan said. “After using the Internet of things, we can notice any movement about the relics at once to prevent such danger.”

The 5G network also will be used to improve tele-meeting through webcams, in which scholars will discuss together to find the best answers to repair and store issues.

8 . One after another, telecommunications giants such as Huawei, Samsung and Qualcomm have announced their latest fifth generation（5G）products with Huawei’s Mate X and Samsung’s Galaxy Fold attracting most eyeballs.

The telecom giants have also announced that 5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. Yet, when reporting about 5G, many reporters have described it as a “much faster” technology than 4G without mentioning any of its other advantages. As a result, the common public idea about 5G is that they could “download a huge 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 3GPP, an international standardization organization, 5G technology can be used for at least three purposes-for connecting everything, reliability（可靠性）of connections, and removing delays.

“Connecting everything” is a proper slogan for 5G technology, without which the Internet of Things would be impossible, For example, self-driving cars contain several kinds of sensors, such as radar, computer vision, and GPS to identify driving routes, obstacles and road signs. 5G technology will link all the elements of a transportation system, such as traffic lights, CCTV cameras and, of course, cars to build up perfect coordination so they can avoid obstacles and move on driving routes, which will help strengthen self-driving technology.

Reliability of connections is another key characteristic of 5G technology, whose use can be spread to other fields where high safety standards are required. For example, in certain surgeries（外科手术）, doctors put nano-robots inside a patient’s body and have to keep constant control over the robots to ensure they work well and do not cause any harm to the patient. This is an area where 5G technology can be of great help, as it can build up reliable and continuous connections between the monitor and the nano-robots.

And removing delays might come in handy especially in online games. Even long after 4G technology was introduced, players continued to complain about losing games because of low speed. This problem can be solved with 5G technology, because it will ensure continuous high speed.

And for those people who think that 5G costs will be very high, they need not worry. The cost problem can be solved in two ways.

First, factories can produce more micro base stations, which not only occupy less space but also cost less. And second, many more terminals（终端）can use a 5G base station compared with a 4G base station. The more terminals using a 5G base station, the lower cost each of them have to pay. Therefore, 5G technology won’t be as costly as you thought.

1. How does 5G technology help improve self-driving technology?

A．It clears me obstacles for the cars.

B．It connects every part of a transport system.

C．It makes the self-driving car run much faster.

D．It controls the traffic lights and CCTV cameras.

2. What is the use of 5G technology in certain surgeries?

A．It ensures high speed for the robots.

B．It helps the robots do the surgeries without doctors.

C．It enables doctors to put nano-robots inside a patient’s body.

D．It makes the connection between the monitor and the robots better.

3. Factories can produce more micro base stations so that _________.

A．people can pay less for 5G	B．5G can be compared with 4G
C．the “5G epoch” can come sooner	D．more terminals can use a base station

4. What’s the best title for the passage?

A．The “5G Epoch” is Coming	B．5G-Less Cost with Higher Speed
C．The Latest Fifth Generation Products	D．5G Technology is more than about High Speed
