2023 年中考英语时事热点阅读专练 热点 64 认识 5G 及其广泛用途 一、阅读理解 1 There has been a lot of news recently about 5G,but what is this technology(技术)and how might it change our lives?What is 5G?5G stands for the next step in the development of technology to replace 4G system.Earlier“G”systems were designed to improve mobile communication operations.The new 5G system is expected to allow more users to do more things at a faster speed.It will move well beyond mobile network technology to influence many more industries than other“G”systems.When will 5G be in use?Before we can all use 5G,wireless companies and phone makers will have to complete a whole new system.New phones and communication equipment(设备)must be built.China is expected to put 5G onto the market sometime in 2020,while European nations are likely to build their systems more slowly over time.In the USA,the first 5G-ready phones can be found in the market in the first half of this year.The first 5G iPhone,however,is not expected until 2020.4G phones will work on 5G networks,but not at 5G speeds.What can 5G do?Wireless industry groups say 5G will help the development of the future“smart cities”.5G is also expected to connect self-driving cars and support new technologies.Higher 5G speeds could also help doctors to commonly do remote operations(远程操作).Factories and businesses could use 5G technology to increase automation(自动化)and improve the collection of information._ Many more kinds of data(数据)will be traveling across 5G networks.Much of the data could include personal details about people,businesses or government organizations.The increased data flow would give internet attackers a lot more possibilities to steal and misuse data.Whats more,the wider use of a 5G wireless network means any breakdown of the system would have more serious results.Such difficulties could influence public safety as well as world economic activity.For example,a failure during a doctors remotely guided operation could lead to the death of a patient.Or a network breakdown could cause self-driving cars to crash.1.The writing purpose of the passage is to_.A.introduce“smart cities”B.introduce the new 5G technology C.tell us 5G technology is not safe D.encourage more people to buy 5G phones 2.Which of the following expressions can be the subtitle of paragraph 5?A.How will 5G systems change the world?B.How will the data be used?C.What are the safety risks?D.What kind of data can networks collect?3.Which of the following expressions is Not True according to this passage?A.Users can do many things at a faster speed on 5G networks.B.5G networks do not support 4G phones.C.5G technology can be used to collect a large amount of information.D.5G develops more slowly in European countries than in China.4.What can we infer(推断)from the passage?A.The network breakdown may lead to some serious results.B.People can buy the first 5G Phone in 2020 in America.C.The new 5G system will influence public safety as well as world economic activity.D.5G technology may improve peoples self-driving experience.2 China is running ahead in 5G.In March,2019,the Shanghai Hongqiao Railway Station became worlds first 5G railway station.Now,it takes only 20 seconds to download a long movie there.We are moving closer and closer to the 5G world.However,the new technology is still strange to most of us.What is 5G,after all?At first,5G is fast.5G will be much faster than todays 4G networks!The first 5G modem(猫，调制解调器)of the IT company Qualcomm supports speeds of up to 5 Gigabytes(千兆字节)per second.Most of us have never experienced anything close to that speed.And we are only talking about the first generation(一代)of 5G modems.Future models are likely to be even faster.But 5G is not all about speed.Have you ever been to a large event where your data(数据)connection slowed down?That is because 4G networks can only support a certain number of devices(设置)per square meter.5G networks will be able to do much better.They can support up to a million devices per square kilometer.Now,you begin to understand why 5G is a huge change over 4G.The technology is not just for the smart phones.It has a strong influence(影响)on every connected device.With 5G,self-driving cars will be able to communicate with the world around them as quickly as possible.Wearables,Pcs and smart home devices will be able to improve as well.Are you looking forward to that 5G world now?5.Each of the following is mentioned about 5G EXCEPT_.A.the first place where 5G is used in the world B.the speed of using 5G to download C.the way of 5G spreading 6.Paragraph 4 shows the advantages of 5G by_.A.using different advice B.comparing 5G with 4G C.some data of 5G networks 7.How many fields of using 5G does the passage tell

Qualcomm produced the first generation of 5G modems.9.Whats the best title for the passage?A.Whats 5G?B.How is 5G used?C.Is 5G good or bad?3 Chinese companies lead in global 5G patent applications with Huawei taking the crown,according to a report by IPlytics,an authorized patent data company.Three companies from China were included in the top 10 list of 5G Standards-Essential Patents(SEPs)family owners,Huawei ranked first.ZTE Corp and China Academy of Telecommunications Technology(CATT)grabbed fifth and ninth places.Chinese companies topped the list with most 5G SEPs applications in communication systems by the end of April 2019,accounting for 34 percent of the worlds total.Chinese tech giant Huawei has taken a leading role by owning 15 percent of SEPs,according to the report“Who Is Leading the 5G Patent Race?”SG SEPs are patents that any company will have to use when carrying out 5G and no one can avoid them.Different from 3G and 4G technologies,5G technology will influence various industries and encourage the appearance of many new products,services and industries.The automotive sector will most likely be one of the first industries to depend on 5G,which will connect vehicles to other vehicles,roadsides,traffic lights buildings and the Internet according to the report.“It is 5G that is going to be a huge jump forward for communication systems because only with 5Gs higher bandwidth can a number of applications be more advanced and used by most consumers,”said Nicole Peng,senior director of the market research company Canalys.As 5G technology has combined various industries and technologies,the number of 5G SEPs rose to more than 60,000 globally by the end of April 2019,the report said.10.Which one was NOT on the top 10 list of

had been used by the end of April 2019.4 The changes in our lives using 5G（使用 5G 给我们生活带来的变化）Do you know 5G?It is the fifth generation（代）of mobile network technology.These new networks are coming.China just issued commercial licenses（发放商用牌照）for 5G on June 6.This means that Chinas telecom companies were soon 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.Whats special about 5G?5G has a very short delay between sending and receiving information.Now,4G takes about 100 to 200 milliseconds(毫秒)to send and receive data.But 5G will get it down to 1 millisecond or lessthis 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(娱乐)5G networks are about 100 times faster than 4G.This means you can download a movie in seconds using 5G.Also,virtual reality(VR)games will become more popular with 5G.The short delay of 5G will make the games feel even more real.5G+transportation 5G will also bring us safer self-driving cars.These cars can send signals(信号)to each other.They also talk to traffic lights and road sensors(传感器).5G will allow cars to react even faster than human drivers.5G+smart homes 5G also makes the Internet of things possible.Internet of things is a large network that connects everything to the Internet.Smart homes are part of it.For example,your toaster can automatically(自动地)start making breakfast after your alarm rings.And if its sensor feels the air becoming dry,a smart sprinkler could water your plants by itself.14.What happened on the sixth day of June according to the passage?A.5G came into use B.China issued commercial licenses.C.Mobile phone users could talk to each other.D.5G delayed between sending and receiving information.15.What does

will change our lives in many ways.D.5G will bring us safer self-driving cars.5 Topic 4G 5G Speed 4G takes about 100 to 200 milliseconds(毫秒)to send and receive information.5G will help cut down the time to 1 milli-second or less.Amusement We can just experience the VR games in special places once in a while.VR games will become more common and exciting with 5G.Traffic Most people cant trust self-driving in 4G because of unexpected problems.5G will make self-driving cars have much faster reaction(反应)than 4G.Smart Homes Just a small part of the house has Blue-tooth to connect in 4G.In smart homes,your home machines can start working ahead of time.5G will not only make our network faster,but change many things in our lives.Although not everyone can use 5G now,China is trying its best to let everyone use 5G as soon as possible.19.When did people use 5G in China?A.On May 30th,2019.B.In June,2019.C.In June,2020.D.Doesnt know.20.How faster is 5G than 4G?A.5G is about 100-200 times faster.B.5G is about 10 times faster.C.4G is as fast as 5G.D.The passage doesnt mention it.21.You can _.A.trust self-driving in 4G totally B.use self-driving cars more safely in 5G C.use

magazine D.a sports newspaper 6 One after another,telecommunications giants such as Huawei,Samsung and Qualcomm have announced their latest fifth generation(5G)products with Huaweis Mate X and Samsungs Galaxy Fold attracting most eyeballs.The telecom giants have also annouced 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 purposesfor 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 patients 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 wont be as costly as you thought.24.How does 5G technology help improve self-driving technology?A.It clears the 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.25.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 patients body.D.It makes the connection between the monitor and the robots better.26.What does the underlined expression“come in handy”in paragraph 6 mean?A.Be fast.B.Be useful.C.Be special.D.Be continuous.27.Factories c
