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.
This modern solution comes thanks to an agreement signed on Friday by the museum and Huawei Co., the telecommunication giant, to build a “smart network” using 5G technology. 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 the handling of a huge number of cultural relics,such as when the priceless painting “Along the River During the Qingming Festival” is exhibited 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 scenario to happen again,” Shan said. “Our operation 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 safeguard the museum’s precious relics. More than 1.86 million of them are housed 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 evil ideas threatens these treasures ” Shan said. “After adopting the internet of things, we can instantly detect any motion involving the relics to prevent such threats.”
The 5G network also will be used to improve remote meeting through webcams, which will discuss with scholars to jointly find the best answers for repair and store issues.
1．What do we know about the Palace Museum
A．Its visitors won't have to queue up for the bathroom.
B．It has served as China’s royal palace for over 500 years.
C．It will cooperate with Huawei to promote its management.
D．It will set up advanced television cameras only for the purpose of safety.
2．What does the underlined word “scenario” in Paragraph 3 mean
A．disaster B．situation C．operation D．exhibition
3．What are the figures in Paragraph 4 intended to show about the Palace Museum
A．It is better than any other museums. B．It has a rich collection of cultural relics.
C．It enjoys great popularity all over the world. D．It faces a tough challenge of protecting relics.
4．With the 5G network, the Palace Museum can ________

If you look at the top of your phone, you can see a little symbol that says 3G or 4G. The “G” stands for “generation (代)” of your mobile network. But the symbols will become things of the past after 5G networks fully arrive.
On March 30, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call. Shanghai has also become the first city in China to start testing 5G networks.
About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won’t just bring faster mobile Internet. People can use it for many other things too.
For example, 5G will help to make self-driving cars faster. Today’s self-driving test cars have one problem—the lag (时间间隔). When the car “sees” an obstacle (障碍物), it sends this information to a data center and receives instructions. However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
5G could also be used to optimize (使最优化) the Internet of Things ( IoT ), that is, a large online network that connects all people and things. Fast Internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your fridge could automatically (自动地) place an order online for eggs when it finds that there are no eggs left inside.

Your Internet experience is terrible when the net speed is too slow—it takes so long to open a web page and the film you’re watching stops every few minutes. That can be very annoying. But it could be a thing of the past. In the near future, major telecom carriers will start to provide 5G services.
What is 5G What difference will it really make to our lives The “G” in “5G” refers to the generations of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster. Now 5G promises much faster data download and upload speeds, and ore stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chat with your friend, there is generally a 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond, which is almost real time.
5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid dangers. Meanwhile, 5G-enabled wearable devices will keep doctors updated on the health status of their patients, so doctors can give patients advice immediately if there’s something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not “travel” far. On 4G networks, you can be 10 kilometres away from the nearest transmission base and barely lose signals. But 5G will only cover about 300 metres, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are currently expensive.
1．What does the “G” in “5G” refer to
A．Games. B．Groups. C．Grades. D．Generations.
2．What is the main idea of Paragraph 3
A．The advantages of 5G. B．The disadvantages of 5G.
C．The price of 5G products. D．The advanced technologies.
3．Which of the following is NOT true
A．3G gave us mobile data and the Internet. B．5G will allow driverless cars to run more safely.
C．5G will cover about 300 metres to 1,000 metres. D．5G will make the VR games feel even more real.
4．Where is the article possibly from
A．A diary. B．A magazine. C．A storybook. D．A novel.
【答案】1．D 2．D 3．C 4．B
【导语】本文是一篇说明文,主要介绍了5G技术的影响和能够带来的改变及仍然存在的问题等.
1．细节理解题.根据第二段中“The “G” in “5G” refers to the generations of mobile network technologies.”(“5G”中的“G”指的是第几代移动网络技术)可知,G指的是“第几代”.故选D.
2．细节理解题.根据“5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment.”(5G将能够改进许多先进技术,如无人驾驶汽车、可穿戴设备和娱乐.)可知第三段主要讲了先进的技术.故选D.
3．细节理解题.根据最后一段“But 5G will only cover about 300 metres, meaning that we will need more transmitters so that we can get signals.”(但5G只能覆盖约300米,这意味着我们需要更多的发射机才能接收信号)可知,C选项“5G将覆盖约300至1000米”表述不正确.故选C.
4．推理判断题.根据第一段“Your Internet experience is terrible when the net speed is too slow—it takes so long to open a web page and the film you’re watching stops every few minutes. That can be very annoying. But it could be a thing of the past. In the near future, major telecom carriers will start to provide 5G services.”(当网速太慢时,你的上网体验很糟糕——打开一个网页需要很长时间,你正在看的电影每隔几分钟就会停止.这很烦人.但这可能是过去的事了.在不久的将来,主要电信运营商将开始提供5G服务.)及结合文章,可知主要介绍了5G技术的影响和能够带来的改变以及仍然存在的问题等.可推知,文章可能来自一本杂志.故选B.

If you look at the top of your phone, you’ll usually see a small symbol that shows 3G or 4G. The “G” means the “generation” of your mobile network. But they will become history after the 5G network fully arrives.
In recent years, China makes great achievements in 5G. Now it’s making efforts to popularize the business use of 5G. Shanghai is the first city in China to start testing the 5G network. On March 30, 2019, Wu Qing, one of the leaders of Shanghai, made the first 5G video call with Huawei Mate Smartphone.
5G allows people to download and upload data faster than ever before. It is 100 times faster than the 4G network. But 5G doesn’t just bring faster mobile Internet. People can use it for many other things as well. For example, 5G can make self-driving cars safer. Today’s self-driving cars have one problem — time lag. When a self-driving car “sees” an obstacle(障碍物), it sends the information to data center and receives instructions. However, it takes time to do that. That’s the time lag. With this kind of lag, the car might have an accident because it doesn’t receive instructions in time. But with 5G, the self-driving car can receive instructions in a shorter time.
5G can also be used to power the Internet of Things(物联网). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with the Internet of Things, your smart fridge could order eggs online when it notices that there are no eggs left inside.

Take a look at your parents’ mobile phone. Can you see a small “5G” at the top Do you know what is it 5G means “5th generation mobile network (第五代移动通信技术)”.
Each mobile network generation is faster and more powerful (有力的) than the one before it. In 1980s, with 1G, we made phone calls for the first time. Around ten years later, 2G let us send messages. Then in 2000s, using the Internet, listening to music and sending emails appeared in people’s life for 3G. Later, we could watch films and even buy things in 2010s with 4G. To our surprise, 5G is coming now. What’s special about 5G
Do you have online classes at home With 5G, you can have classes outside your home. The class can go as well as the ones you have at home. Students from poor areas (地区) can have the chance to study just like you do.
In some movies, you might see cars that can drive by themselves—you tell them where you want to go, and they take you there as fast as possible. With 5G, cars like this may appear in our life. It makes self-driving cars safer. These cars can send messages to each other. They can also “talk” to traffic lights. 5G will make cars move even faster than human drivers.
5G networks are about 100 times faster than 4G. This means you can download (下载) a movie in seconds using 5G, and makes your video calls clearer. What’s more, VR games will become more popular with 5G. It will make the games feel even more real.
All in all, 5G will change the way people live and make our life more comfortable and convenient (方便的) than ever before. You won’t have to wait too long to enjoy it. Now you can buy a new mobile phone to use 5G networks. 5G phone cost 8,000 yuan right now. But experts say that about one and a half years later, the price could go down to around 2,000 yuan. Why not try 5G

With the rapid development of wireless technologies, the Fifth Generation (5G) mobile communication system started to come. Although the development of 5G network technology in the international community is still in the research stage, a number of foreign countries and organizations are working on it. China started late in network technologies. In order to catch with the times, China also needs to have its own place in such a competitive environment.
There are some quick changes in China’s telecom space. With the 4G network now widely used, China is now preparing to enter 5G age. China has started research and development on the 5G network and plans to finish the network testing by around 2019.
It’s expected that just one standard will be used globally (全球的) with the 5G technology. “Under the identical standard, different companies can be connected, and form a competitive environment. Therefore, we can make sure that companies can gain reasonable profits (利润), and at the same time provide faster, better, more convenient and cheaper services to people.” Wu Ku, Director of Dept. of Science &Tech., MIIT said.
Wu Hequan from Chinese Academy of Engineering said, “5G will make it possible to connect one million devices to the so-called Internet of Things within one square meter. In the future, it will also be used on high-speed trains moving as fast as 500 kilometers per hour. In the area of the Internet of Vehicles (汽车), it can be used in unmanned vehicles, assisted driving and the management of smart cities.” Wu Hequan believes China’s future Internet will be faster, more intelligent and safer.
Chinese government pays more attention to the development of 5G and in more open to it. With the shared effort of the industry, China will play an increasing important role in the global 5G development.
