专题04 5G技术
Passage 1
（2021·宁夏长庆高级中学高一期末） We have heard some interesting ways that 5G wireless(无线的) technology might change our lives in the future.
5G technology promises the internet speeds between 50 to 100 times faster than 4G systems. While 5G is set to be used in some limited areas of America this year, much of the world is not expected to receive widely used service 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 seeks to explore 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 5G technology tools 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 Reauters 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.
1．What is the aim of Cisco Systems Inc’s project?
A．To win financial support from the British government
B．To test the effects of 5G technology on animals
C．To promote its technological development in Britain
D．To expand the future use of 5G in countryside
2．What does the underlined word “it” in paragraph 3 refer to?
A．The project B．The company
C．The technology D．The group
3．What can we learn about 5G according to the text?
A．It is no worse than 4G in terms of speed
B．It is already widely used all over the world
C．It has made improvements in operating the cows
D．It is based on sensors and machine learning
4．In which part of a newspaper may this text appear?
A．Entertainment B．Lifestyle
C．Education D．Technology

【答案】
1．D 2．A 3．C 4．D

Passage 2
（2020·云南丽江市·高一期末） Your Internet experience is ruined when the net speed is too slow – it takes so long to open a web page and a video you’re watching stops every few minutes. That can be very annoying.
But it could be a thing of the past. On June 3, the Ministry of Industry and Information Technology announced that China would issue（颁发）licenses of 5G. It means the age of 5G is coming.
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 means much faster data download and upload speeds, and more stable(稳定的) connections. It also 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 100 to 200 milliseconds(毫秒) delay with 4G, but 5G will reduce the delay to 1 millisecond or less, which is almost real time.
What changes will 5G bring us?
According to the Straits Times, 5G will be able to improve many advanced technologies, such as driverless cars, 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 potential(潜在的) dangers. Besides, VR（虚拟现实） games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
Does 5G have any disadvantages?
According to the BBC, 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 kilometers away from the nearest transmission base（传输基地）and hardly lose signal. But 5G will only cover about 300 meters, meaning that we will need more transmitters（发射器） 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 expensive at present.
5．According to the text, we know that ________.
A．You can surf the Internet with 2G service.
B．You can have a video chat with your friend with 4G service.
C．You can use any mobile phone to experience 5G services.
D．You can download an entire HD movie in seconds using 3G services.
6．In the passage the function of the first paragraph is to ________.
A．introduce the topic of the text.
B．tell readers some feelings.
C．explain what 5G is.
D．make a comment of Internet experience.
7．Why can driverless cars be more safely with a 5G network?
A．Because the short delay of 5G will make driverless cars feel even more comfortable.
B．Because driverless cars will be able to communicate in real time and avoid potential dangers.
C．Because the drivers will be more careful.
D．Because the drivers will hardly lose signal with5G network.
8．Which of the following best explains “travel” underlined in the last paragraph?
A．旅行 B．盛行
C．传输 D．移动

【答案】

Passage 4
（2021·六盘山高级中学高三二模） One after another telecommunications giants 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 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 HD 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—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, and thus establish high-speed coordination among them, and help the chips inside the terminals timely react to meet people’s needs. Take autonomous vehicles for example, they 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 a technology that can be of great help, as it can establish reliable and continuous connections between the monitor and the nano-robots.
13．Which of the following can serve as an example of "connecting everything"?
A．Improvement of smart phone signals. B．Decrease in telecommunication cost.
C．High speed in playing computer games. D．Online tests for all members at the same time.
14．Why can 5G be used in the fields with high safety standards?
A．It can attract most eyeballs on a massive scale.
B．It can provide dependable and constant service.
C．It offers massive machine types of communication.
D．It employs 4G base stations and occupies less space.
15．What will the author most probably discuss in the following paragraph?
A．Eliminating delays. B．5G network capacity
C．Disadvantages of 5G D．Building 5G base stations
16．What would be the best title for the passage?
A．5G Technology: More than about High Speed
B．5G Technology Will Shape the Future of Connectivity
C．Telecom Giants Work Together to Better 5G Technology
D．Advantages and Disadvantages of 5G Technology and Products

【答案】
13．D 14．B 15．A 16．A
【分析】
这是一篇说明文。文章主要介绍除了高速，5G技术还有连接一切、连接可靠性以及消除延迟等特点。
13．推理判断题。根据第三段中“5G would enable one server to connect to multiple terminals and thus establish high-speed coordination among them, and help the chips inside the terminals to timely react to meet people’s needs.( 5G能让一个计算机服务器连接到多个终端，然后在它们之中建立高速协调，并且帮助在终端里面的芯片能够及时做出反应满足人们的需求)”结合选项可推知，选项D表达的是“同时对所有成员进行网络测试”，符合5G的连接一切的特征，可以作为5G连接一切这个特征的具体举例。故选D。
14．细节理解题。根据第四段中“This is an technology can be of great help, as it can establish reliable and continuous connections between the monitor and the nano-robots.(这是一项非常有帮助的技术，因为它能在监控器和纳米机器人之间建立可靠而且持续的连接)”可知，5G技术能够在高安全标准的领域使用，是因为它能提供可靠而且持续的服务。故选B。
15．推理判断题。根据第二段中“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.(根据3GPP，一个国际标准化组织的标准，5G技术能够在至少3个方面使用，分别是：连接一切、连接的可靠性以及消除延迟)”；第三段中““Connecting everything” is an appropriate slogan for 5G technology, without which the Internet of things would be impossible.(连接一切对于5G技术来说是一个合适的口号，没有这个特征因特网的所有事情都将变成不可能)”以及第四段中“Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required.(连接可靠性是5G技术的另外一个基本特征，这一技术的使用可以延申到要求高安全标准的其他领域)”可推知，作者接下来可能会讨论的是5G技术的消除延迟这个特征。故选A。
16．主旨大意题。根据第二段“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—connecting everything, reliability of connections, and eliminating delays.(实际上，除了速度，5G技术比4G有更多的优势。根据国际标准化组织3GPP的标准，5G技术至少可以用于三个目的：连接所有东西、提高连接的可靠性和消除延迟)”结合文章主要介绍除了高速，5G技术还有连接一切、连接可靠性以及消除延迟等特点。可知A选项“5G技术：不仅仅是高速”最符合文章标题。故选A。

Passage 7
（2021·山西忻州市·忻州一中） Beginning 2020, the fifth generation of wireless technology is expected to be widely used throughout the world. The new network, called 5G, promises to give faster speeds and a higher capacity for the use of more devices. However, while some companies are competing to be the first to deliver 5G to the consumer, the environmental influences of the new network are being overlooked.
There is some evidence that the new devices and technologies associated with 5G will be harmful to ecosystems. The main component of the 5G network that will affect the earth's ecosystems is the millimeter waves. The millimeter waves that are being used in developing the 5G network have never been used at such scale(规模)before. Studies have found that there are some harms caused by these new technologies.
The millimeter waves, specifically, had a detrimental effect on birds. In a study, researchers observed that after exposure to radiation from a cell tower for just 5~30 minutes, the eggs of sparrows were disfigured. The disfiguration of birds exposed for such a short amount of time to these frequencies(频率)is significant considering that the new 5G network will have a much higher density(浓度)of base stations(small cells) throughout areas needing connection. The potential dangers of having so many small cells all over areas where birds live could threaten their population's survival.
Additionally, it was found that cellular devices were linked to many disturbances in the ecosystems of bees. In this study, beehives exposed for just ten minutes to 900MHz waves fell victim to colony collapse disorder(蜂群崩坏症候群). Bees are an incredibly important part of the earth's ecosystem. Around one-third of the food produced today is dependent on bees for pollination(授粉), making bees are a vital part of the agricultural system.
The impact that the cell towers have on birds and bees is important to understand, because all ecosystems of the earth are interconnected. If one component of an ecosystem is disrupted the whole system will be affected.
26．What will probably cause the environmental problems with the wide use of 5G network?
A．The lack of the density of base stations.
B．The less mature devices and technologies.
C．The lower capacity for the use of devices.
D．The large amount of use of millimeter waves.
27．Which of the following best explains the underlined word "detrimental" in Paragraph 3?
A．Important. B．Unknown. C．Harmful. D．Potential.
28．Why are bees important in the earth's ecosystem?
A．They play a key role in food production.
B．They can guide some pollinators to work.
C．They are likely to reduce unpleasant noises.
D．They rid disturbances in the agricultural system.
29．What is the best title for the text?
A．Should 5G Be Used in the Future? B．The Influence of 5G on Ecosystem
C．The Research on 5G Technologies D．How Can Ecosystem Survive 5G?

【答案】
26．D 27．C 28．A 29．B
【分析】
本文是一篇说明文。主要介绍了5G网络技术使用的毫米波对环境的破坏，影响了鸟类、蜜蜂等的飞行，从而影响了地球的整个生态系统。
26．细节理解题。根据第二段“The millimeter waves that are being used in developing the 5G network have never been used at such scale(规模) before. Studies have found that there are some harms caused by these new technologies.( 用于开发5G网络的毫米波以前从未以如此规模使用过。研究发现，这些新技术造成了一些危害。)” 可知，5G 网络的问题是大量使用毫米波会影响生态环境。故选D。
27．词句猜测题。根据划线词后“In a study, researchers observed that after exposure to radiation from a cell tower for just 5~30 minutes, the eggs of sparrows were disfigured.( 在一项研究中，研究人员观察到，麻雀的卵在暴露于基站辐射5~30分钟后外形就会被毁。)”可推断，毫米波对鸟类有不利影响。画线词的意思与harmful“有害的”的意思最为接近。A. Important.重要的；B. Unknown未知的；C. Harmful有害的；D. Potential有潜力的。结合各选项的意思，故选C。
28．细节理解题。根据第四段“Bees are an incredibly important part of the earth's ecosystem. Around one-third of the food produced today is dependent on bees for pollination(授粉), making bees are a vital part of the agricultural system.( 蜜蜂是地球生态系统中极其重要的一部分。今天生产的食物有三分之一依赖蜜蜂授粉，使得蜜蜂成为农业系统的重要组成部分。)” 可知，蜜蜂可以授粉，所以它们在食物生产过程中起着重要的作用。故选A。
29．主旨大意题。通读全文，尤其是文章第一段“However，while some companies are competing to be the first to deliver 5G to the consumer, the environmental influences of the new network are being overlooked.( 然而，尽管一些公司正在竞争成为第一个向消费者提供5G的公司，但新网络的环境影响却被忽视了。)”及第二段“There is some evidence that the new devices and technologies associated with 5G will be harmful to ecosystems.( 有证据表明，与5G相关的新设备和技术将对生态系统有害。)”可知本文主要介绍了 5G 对生态系统的影响。结合选项可知选项B. The Influence of 5G on Ecosystem(5G对生态系统的影响)概括较为全面准确。故选B。
Passage 8
（2021·山西） It’s easy to forget what communications life was like before 4G. Since its introduction around 2010, mobile subscribers using 4G have enjoyed excellent connectivity.

Passage 9
（2021·浙江高二月考） With 4G still being used in many parts of the world, 5G mobile technology is on its way-and the effect will likely cover more areas beyond the telecoms(电信) industry. With more devices (设备)being connected and different players entering the field, it becomes difficult to set a global standard. The question is what a 5G network will look like.
The race is on to provide an answer. Last month America's largest two mobile operators said they would begin testing. Japan wants a 5G network in place for the Olympics Games in 2021. Recently a series of new 5G cooperation was announced. Devices makers such as China's Huawei presented devices and technology.
There is no lack of enthusiasm, or willingness to make large investments(投资). Nor is there a shortage of demand, as rapid growth in data traffic increases pressure for a better wireless network. There is, however, a lack of agreement on various issues, for example which band of wireless technologies to use, and what standards to set for network devices and handset makers. Until now the telecoms industry has agreed only on general set of requirements about connection speeds and response times. The matter grows more complex as more types of players enter the field. Media companies want generous bandwidth for streaming. Internet firms want low power consumption. The online gaming companies are worried about response times.
Most important of all are the big technology firms. Companies need to sell more smart phones and other mobile devices. They also want to make a lot of money. Even Google has also shown an interest in 5G. One of the biggest questions is how 5G could change the industry's structure. Some say that further relief is unavoidable. 5G could bring about the long-expected combination of computer and telecoms devices makers.
34．What can we learn from the first two paragraphs?
A．5G technology is being used in most countries.
B．The competition in 5G technology is being heated up.
C．The telecoms industry set up a global standard for 5G network.
D．Huawei will provide sports devices for the 2021 Olympics Games.
35．Which word best describes the author's attitude towards 5G technology?
