备战2023年高三英语阅读理解热点话题分类训练
(2022·陕西·长安一中高一期末)5G wireless networks are ready to power the cities of tomorrow. However, exact implementation (实施) of 5G will vary from city to city, with each city having its own unique set of priorities, requirements, and objectives.
Since 5G enables countless service possibilities, cities must develop strategies around their specific needs. Business and civic leaders play a decisive role in this process, helping to drive smart city initiatives and ensuring that key infrastructure (基础设施) elements are in place.
Several urban areas, including Los Angeles, Dallas, Houston, Atlanta, and Chicago, are early to benefit from 5G. For operators, these large urban centers offer a critical mass of solid infrastructure to support 5G’s complex technology requirements.
Now, regional and local governments play a critical role in positioning their cities to become early 5G adopters. They have a growing responsibility to streamline the permitting process, change fee structures, and minimize regulator hurdles in order to enable greater 5G implementation.
Efforts are already in full force by industry players to overcome challenges for a smooth build out in areas where 5G is needed first. As business leaders take a more active role in ensuring that they are well positioned to better 5G services, they also increase their ability to transform their organizations into smart companies. Peter Linder, head of 5G marketing for North America at Ericsson, emphasizes the critical role individual leaders can play in making 5G and smart cities a reality.“5G will be introduced in urban areas first, driven by consumer and business’s needs,” he says.“Proactive city leaders appreciate the potential value of 5G for developing smart city solutions and will partner with service providers to speed up vital network development.”
The role of business and civic leaders as stimulators for encouraging 5G adoption is decisive to creating smarter, safer, and cleaner cities. The time is right for urban leaders and business executives (执行官) to work together toward making smart cities a reality.
1.What’s the key factor in 5G implementation
A.Promising values.
B.Solid infrastructure.
C.Individual leadership.
D.Leaders’ promoting role.
2.What should a concerning government do for 5G
A.Establish more smart companies.
B.Tap the value of 5G application.
C.Meet the needs of 5G adoption.
D.Collect money from local residents.
3.Which of the following words can best replace the underlined word in paragraph 5
A.Vital. B.Smart. C.Minor. D.Serious.
4.What is the author’s attitude towards 5G implementation
A.Negative. B.Positive. C.Uncaring. D.Doubtful.
(2022·全国·高三)All networks like 3G and 4G will be things of the past, because 5G will be reachable in the near future. So, what’s so special about a 5G future First of all, its download speed can be as fast as 20GB/s, which is 100 to 200 times that of 4G. But what’s more impressive is 5G’S low delay rate. Now, 4G takes an average of 200 milliseconds (毫秒) to send and receive information. But 5G will get it down to 1 millisecond.
5G is a great breakthrough (突破). It’s going to change the way equipment connects to the Internet, and more importantly, to each other. And self-driving cars may be one of the biggest breakthroughs to come out of 5G. Human reaction time is 200 milliseconds, yet we still have accidents every day. The self-driving car under a 5G network could react and communicate its reaction to hundreds of cars around it, all within 1 millisecond. It’ll play a great role in preventing car accidents and ending traffic jams completely.
5G can benefit us in many other ways. Operations could be performed by robots controlled by experts from the other side of the world. Therefore, more lives will be saved in time. Factories can be staffed by robots that can communicate their tasks to each other, and they can do more work efficiently over a 5G network. Imagine a group of drones (无人机) flying over a field of crops, using sensors (传感器) on the ground to sort, pick, feed, and water plants all on their own. Then farmers won’t have to work so hard anymore.
But, 5G is not perfect. One major disadvantage has to do with why it’s so fast. 5G uses the millimeter waves, while 4G uses the 15 to 40 centimeter-long waves. And shorter waves go fast but not very far. On 4G networks, the signal can go 10 kilometers. But the 5G signal can go at most 300 meters, and it can’t even go through walls or rain. So, what does that mean Having such a short signal distance means we need to build a lot of transmitters (信号发射塔) in the future.
5.How does the author show us 5G’s advantages in Paragraph 1
A.By giving examples of the uses of 5G.
B.By making comparisons between 4G and 5G.
C.By explaining the scientific principles of 5G.
D.By analyzing 5G’s development from 4G.
6.According to the author, the self-driving cars will ______.
A.cause more car accidents
B.slow down 5G’s development
C.ran without being connected to the Internet
D.have a much faster reaction speed than humans
7.What does the underlined part “be staffed by robots” in Paragraph 3 mean
A.Be built by robots.
B.Have robots as workers.
C.Offer employees home robots.
D.Produce more medical robots.
8.What is the main idea of the text
A.The development of 5G is challenging.
B.Some disadvantages of 5G network remain to be improved.
C.5G network could be applied to hospitals, factories and drones.
D.5G is a great breakthrough and can benefit people in many ways.
(2022·浙江·嘉兴市第五高级中学高三期中)We have recently heard some interesting ways that 5G technology might change our lives in the future. 5G promises internet speeds between 50 to 100 times faster than 4G systems. Such improvements are sure to be popular with 5G users worldwide. While it is set to start only in just a few areas of the United States this year, much of the rest of the world is not expected to receive this service until 2023.
One project in Britain, though, is already testing this superfast technology, but not on humans. Instead, the experimental subjects are an unlikely group of internet users – cows. The system connects the animals to 5G in an effort to automate (使自动化) the milking process.
The project was developed by American technology company Cisco Systems. Testing areas were set up at farm in three rural (农村的) areas of England. The cows are equipped with 5G-connceted devices (设备) that link up to a robotic milking system. The system uses sensors and machine learning to fully automate the process.
System designers say technology takes over after a cow feels ready to be milked and walks toward an automatic gate. The device is designed to recognize each cow. It then positions equipment to the right body position for milking. During the process, machines offer food for the cow as a reward.
One of the test areas is in the town of Shepton Mallet in southwest England. There, about 50 of the farm’s 180 cows are fitted with 5G smart collars and ear sensors(传感器). Project officials say the devices do not harm the cows and the sensors help farmers immediately find problems or health concerns.
Duncan Forbes, the project leader, told Reuters that so far, he thinks the project shows the farm’s cow operations can be greatly improved with 5G technology.
Forbes added that the experiment provides strong evidence that 5G technology can be widely used in the future “not just on farm, but in rural communities right across the country.”
9.What do we know about 5G technology from the first two paragraphs
A.It has changed our lives. B.it has more users than 4G.
C.It has not been widely used. D.It has been used on cows in the US.
10.What is paragraph 4 mainly about
A.The introduction of 5G devices. B.The milking process with 5g technology.
C.The purpose of system designers D.The way machines provide cows with food.
11.Why are some cows equipped with ear sensors
A.To recognize every cow. B.To judge the position of the cow.
C.To reduce the harm from devices. D.To find health problems in cows.
(2022·全国·高三)Do you know 5G It is the fifth generation of mobile network technology. These new networks are coming.
China just issued commercial licenses for 5G on June 6, 2019. This means that China’s telecom companies will be able to offer 5G networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What’s special about 5G
5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.
This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.
5G + entertainment
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.

(2022·湖北·高二期末)China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration (渗透) by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.
The GSMA said that China’s three major mobile operators—China Unicorn, China Mobile, and China Telecom—are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
One of the most distinguishing factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China’s seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation’s total connections will be 5G, according to GSMA.This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent.

(2022·江西抚州·高三期末)We have heard some interesting ways that 5G wireless technology might change our lives in the future. 5G technology promises the internet speeds between 50 to 100 times faster than 4G systems. Despite used in some limited areas of America this year, 5G is not widely used until 2023.
One project in Britain, however, is already testing this super-fast technology on an unlikely group Internet users—cows. The project was developed by American technology company Cisco Systems, Inc. It also receives money from the British government. Cisco says the program wants to enlarge the future of 5G in countryside areas around the world.
Testing areas were set up at farms in 3 countryside areas of England. The cows are equipped with 5G devices (装置) that connect to a robotic milking (挤奶) system, which uses sensors (传感器) and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks towards an automatic gate. During the milking, machines give food for the cow as a reward.
Other technology tools powering the 5G smart farms include automated brushes that turn on when the cow rubs up (蹭) against them. Sensors also control the amount of light to the cows living areas depending on the weather. And, an automatic feeding system makes sure the animals always have enough to eat.
Duncan Forbes, head of a government-funded agricultural engineering organization, told Reuters that the project shows the farm’s cow operation can be greatly improved with 5G technology and that the experiment provided strong evidence that 5G technology can be widely used in the future, not just on farms in Britain, but in countryside across the world.

(2021·甘肃·民勤县第四中学高三期中)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 more 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.
29.What does the “G” in “5G” refer to
A.Games. B.Groups. C.Grades. D.Generations.
30.What question does Paragraph 4 answer
A.How much does 5G cost in real time. B.Why will 5G reduce the delay.
C.How will 5G improve the driverless cars. D.What changes will 5G bring us
31.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.
32.Where is the article possibly from
A.A diary. B.A magazine. C.A storybook. D.A novel.
