备战中考英语阅读理解热点话题+体裁分类训练(中考真题+各地模拟题)专题5G技术Passage 1（2021·四川达州·中考真题）In 1987 a small company named Huawei was started in Shenzhen. After more than 30 years of development, the company has now beaten Apple and become the world’s second largest make r of smartphones. It has also become the world’s supplier (供应者) of 5G. In China and even in the world, Huawei is a wonder. Although it started producing mobile phones not many years ago, it has become one of the most famous phone companies.But recently, Huawei faces some difficulties. The US government made a law to stop its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the US government planned to stop selling parts and se rvices to Huawei. They believed that Huawei’s business would be hurt this way.“We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information,” Ren Zhengfei, Huawei’s president s aid. “The law would have little effect on our company. Huawei has enough ability to deal with the problems,” Ren added.In an interview several years ago, Ren Zhengfei said, “I started Huawei with only £4000 at the beginning, but now it has become a 100 billion company. The experience was not as romantic as you imagine.”Facing the law of the US, Huawei is growing. Huawei’s smartphone sales around the world rose 50 percent compared with a year earlier in the first three months of 2019. At the same time, sales from both Samsung and Apple fell. So far Huawei has grown into the world’s largest telecommunication equipment supplier (供应商), selling in 170 countries. It may beat Samsung as the largest smartphone maker in the near future.1．How many kinds of smartphones are mentioned in total in this passage?A．One. B．Two. C．Three.

It is a new network after 1G, 2G, 3G and 4G. It can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data speed. One can download a two-hour movie for fewer 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 and can order 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 our life and the world. The same will surely be true of 5G.

Three companies from China were included in the top 10 list of 5G Standards-Essential Patents(SEPs) family owners. Huawei rainked first. ZET Corp. and China Academy of TelecommunicationsTechnology ( CATT) grabbed fifth and ninth places, respectively.Chinese companies topped the list for most 5G SEPs applications in communication systems by the end of April 2019, a ccounting for 34 percent of the world’s total. Chinese tech giant Huawei has taken a leading role by owning 15 percent of SEPs, according to the试卷第4页，共11页report Who Is Leading the 5G Patent Race?5G SEPs are patents that any company will have to use when carrying out 5G technology 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 on ly with 5G’s higher bandwidth can a number of applications be more advanced(尖端的) and used by most consumers.” Said Niclole 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. 15．What does “taking the crown ” probably mean in Paragraph 1?A．becoming the next king B ．finishing the task betterC．being in the first place D．wearing the hat of the king 16．Which one was NOT on the top 10 list of 5G SEPs?A．Canalys.

However, not too long from now, 5G will make them much more common both at work and in our homes. You might see people wearing AR glasses or VR headsets* while waiting for the bus or sitting in the office.One of the most expected changes will be VR and AR’s influence on the gaming industry. Nowadays, most VR games are limited when compared to the latest console games*. With the power of 5G, VR gamers will be able to see, hear, and feel virtual environments without waiting. What’s more, if you want to play a game using a VR headset, you need a machine such as a PC or a gaming console that has a large amount of storage. This means you usually have to stay in one place while playing VR games. The arrival of 5G means we will be able to move advantages and disadvantages away from the PC and into the cloud so that we only need a headset. You will be able to play VR games anywhere in real time with a headset.Such headsets and other 5G wearables will also bring great changes to the workplace. In 5G smart factories, for example, all of the equipment is connected to a single network. Workers can use 5G headsets when solving problems. Using AR headsets, they can be informed about a problem and shown how to fix it through a heads-up display.AR adds digital elements* to real-world environments through a smartphone or a pair of smart glasses. One example is Nintendo’s AR Pokemon Go game, which uses a phone’s GPS to show Poké mon as if they are actually in the real world. VR is total immersion* in a 3D computer-generated environment. Users can interact with the environment using VR headsets and gloves. VR is typically used for computer games or in exhibitions.20．In Paragraph 1, we know that ________.A．It is common to see people wearing AR glasses nowB．5G will make AR and VR technology more popular试卷第6页，共11页C．VR and AR technologies solved lots of problems in officesD．people will use AR and VR for games only in bus stations21．Why will VR change the gaming industry with the power of 5G? ________. A．Because 5G can improve the VR experienceB．Because 5G will make VR games more expensiveC．Because most console gamers will become VR gamersD．Because console gamers like to use VR technology more22．What do we know about VR games at present? ________.A．Just a headset is enough for VR playersB．Everyone can afford the price of VR games nowC．The players must stay in one place while playingD．Workers can solve problems while playing VR games23．The purpose of this passage is to tell people ________.A．the history of AR and VR B．the benefits that 5G will bring C．how to play AR and VR games D．what the latest console games are Passage 6（2021·江苏盐城·二模）If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G. The “G” stands for the “generation” of your mobile network. But these symbols will become things of the past after 5G fully arrives.On March 30th, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.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 big change will not only make our mobile Internet faster. It can be used in many other ways as well.For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem—lag. When the car “sees” an obstacle (障碍物), it sends this information to a data center and receives instructions. However, it takes time to send and receive 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, according to CNN.5G could also be used to power the Internet of Things (IOT). This refers to a large online试卷第7页，共11页network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your fridge could automatically (自动地) place an order online for eggs when it finds that there are no eggs left inside.All in all, 5G will shape every type of technology that it touches. And you won’t have to wait too long for that to happen.24．The writer uses self-driving cars as an example to ________.A．explain how self-driving cars workB．show us the advantages of self-driving carsC．warn about the possible dangers of self-driving carsD．explain how 5G ’s fast speed can be helpful25．The underlined word “lag” probably means “________” in Chinese.A．延迟B．迷路C．暂停D ．耗电26．The fridge is mentioned to ________.A．describe the importance of IOTB．encourage people to try the new productC．introduce how to use the Internet of ThingsD．show 5G would make IOT more powerful27．Which of the following would be the best title of the passage?A．Can 5G go any further? B．5G has changed our lifeC．5G is on the way D．China is leading the world in 5G Passage 7（2021·广东·秀全中学一模）Some people like the freedom of driving their own cars. But others find driving to be inconvenient or even dangerous. Fortunately, the driverless cars we've seen in movies and TV shows are on the way here.The first driverless car to hit the screen was Herbie, a cute talking car from the 1968 comedy The Love Bug. Herbie could drive by himself and even talk to his human friends He didn't have any advanced technology—just magic.KITT was another driverless car that appeared on the 1980s TV show Knight Rider. KITT used advanced Al to drive itself and help its rider Michael Knight catch criminals.试卷第8页，共11页While the driverless cars of today can't talk to us, they do have many similarities to the ones we've seen onscreen. Nearly every major car company is working on their own autonomous, vehicle（A V）. Tesla, for example. has developed a driver-assistance system for its cars called Tesla Autopilot.Tesla Autopilot can complete many of the tasks hat human drivers usually do. It can make sure that your car is centered in the correct lane, as well as park itself and stop if it thinks that a crash might happen. However, it is not fully self-driving.Google's sister company Waymo seems to be leading the way in the A V area. Itsself-driving cars are already being used for taxi services in the US city of Phoenix. It is the only self-driving car service that operates without human backup drivers. It uses common cameras as well as laser radar to determine distance, which allows the cars to get around without risk of crashing.Although companies are making great progress in developing A V. there is still a lot of work to be done. Year after year, companies promise that fully self-driving cars will become widely available. But nearly all of these promises have fallen through.One of the problems is that designing a self-driving car that is safe and easy to use is much harder than people realize. Self-driving cars have to analyze millions of data-points in order to prevent accidents and choose the correct route. Humans are used to doing this—but designing an Al that can work like human mind to make a decision quickly is very difficult.However, as new technologies like 5G develop, fully self-driving cars will come closer to reality.28．What were Herbie and KITT?A．They were interesting TV shows. B．They were driverless cars onscreen. C．They were cars using advanced AI D．They were owners of driverless cars 29．Tesla Autopilot can________.A．talk to his human friends clearly B．stop to avoid a crash happeningC．do all the tasks as human drivers D．fly for a short while if necessary 30．What does "It" in Paragraph 6 refer to?A．The company of Google. B．The US city of Phoenix.C．The self-driving car service D．A car with backup drivers.31．How might the future of the fully self-driving cars be according to the passage?A．It will be too hard to design a self-driving car that is safe and easy to use试卷第9页，共11页B．Designing an Al that can make a decision like human mind is impossible.C．Fully self-driving cars that are widely used must come to reality years later.D．New technologies will speed up the development of fully self-driving cars.Passage 8（2021·陕西宝鸡·一模）If you look at the top of your phone, you’ll usually see a little symbol that say s 3G or 4G. The “G” stands for the “generation” of your mobile network. But the symbols will become things of the past after 5G networks fully arrive.Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. 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 as well.For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem-when they found something in front, that is too late to stop at once. When the car “sees” something in front, it sends this informatio n 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(滞后), the cars might crash because they don’t receive instruction in time. With 5G, this lag will be greatly lowed, making the cars safer.5G could also be used to power the Internet of Things(IOT), that is, a large online network that connects all things and people. 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 refrigerator could automatically place an order online for eggs when it finds that there are no eggs left inside.32．According to the passage, people in Shanghai ________.A．have used 5G networksB．have tested 5 in Nokia CompanyC．have tested 5G networks under the leadership of WuD．have succeeded in working by 5G33．The writer uses self-driving cars as an example to ________.A．explain how 5G’s fast speed can be helpfulB．warn about dangers of self-driving carsC．explain how self-driving cars work试卷第10页，共11页D．tell us the reason why Shanghai people like to use self-driving by 5G 34．What can we infer(推测) according to the passage?A．5G is widely used in China now.B．5G networks will make our lives more convenient.C．There are no symbols at the top of our phones.D．5G can’t be faster than 4G.35．The last paragraph tells us IOT means________.A．a robot that can do houseworkB．an online store where you can buy everythingC．a large online network that connects things and peopleD．5G can give us free eggs when we have no eggs in our refrigerators参考答案1．C2．B3．A4．D【分析】本文主要介绍了华为在手机在这一产业的发展历程，它现在所面临的困境，以及它能够解决这些困境的决心和前景。

The “G” stands for the “generation” of your mobile network. But these symbols will bee things of the past after 5G fully arrives.On March 30th, 2019, Shanghai vicemayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also bee the first city in China to start testing 5G networks.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 big change will not only make our mobile Internet faster. It can be used in many other ways as well.For example, 5G will help to make selfdriving cars safer. Today’s selfdriving test cars have one problem—lag. When the car “sees” an obstacle (障碍物), it sends this information to a data center and receives instructions. However, it takes time to send and receive 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, according to CNN.5G could also be used to power the Internet of Things (IOT). 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 IOT under 5G, your fridge could automatically (自动地) place an order online for eggs when it finds that there are no eggs left inside.All in all, 5G will shape every type of technology that it touches. And you won’t have to wait too long for that to happen.41．The writer uses selfdriving cars as an example to ________.A．explain how selfdriving cars work B．show us the advantages of selfdriving carsC．warn about the possible dangers of selfdriving cars D．explain how 5G’s fast speed can be helpful 42．The underlined word “lag” probably means “________” in Chinese.A．延迟B．迷路C．暂停D．耗电43．The fridge is mentioned to ________.A．describe the importance of IOT B．encourage people to try the new productC．introduce how to use the Internet of Things D．show 5G would make IOT more powerful44．Which of the following would be the best title of the passage?A．Can 5G go any further?B．5G has changed our lifeC．5G is on the way D．China is leading the world in 5G参考答案：1．B2．C3．D4．A5．C【分析】本文介绍了5G即将到来。

《Wi-Fi》初中说明文阅读题及答案①Wi-Fi是英文WirelessFidelity的缩写，是一种把以太网和无线通信结合起来的技术，能够让计算机和其它电子设备不用线路连接就可以在局域网中发送和接收高速数据。

这种网络的唯一缺点是通信距离很短，只有几百米。

但是如果使用定向天线来加强无线信号的话，通信距离就可以达到1公里以上。

定向天线的构造十分简单，只要在一个金属圆筒中放入合适的能加强信号的介质就可以了。

②一台装有无线网卡的笔记本电脑，可以在任何一个Wi-Fi基站周围半径300米的范围内实现无线上网。

无线网卡其实是一种带有天线的调制解调器，目前它所提供的上网速度可以达到每秒11Mb。

③连接的Wi-Fi网络可以覆盖公寓楼、校园和整个社区，无须为每栋楼挖开街道以铺设光缆，也不用搭建一座座发射塔，Wi-Fi技术可以既便宜又轻松地扩展网络连接光缆，其覆盖范围可以让所有信息流汇集到高速光纤主干网络的各个节点上。

④不过需要提醒的是，如果Wi-Fi使用不正确，也极可能对人体造成伤害。

那么，作为普通用户，在使用无线路由器时应该注意什么呢?⑤首先，人体接受的辐射量跟频率有关，频率越高，伤害越大。

因此，家中没有必要使用功率过大的无线路由器。

⑥其次，辐射危害大小还跟距离有关，距离越远，危害越小。

如果家中有孕妇、小孩、老人或免疫力低下者，最好让无线路由器与他们的活动范围保持较远的距离。

⑦第三，最好不要将Wi-Fi设备放置在卧室内，尤其是放在床边。

如果不使用Wi-Fi，最好将无线路由器关闭，以降低不必要的风险。

⑧还有，别在腿上使用笔记本电脑，最好将电脑放在桌子或托架上。

20.下面对选文内容的理解与分析，不正确的一项是A.文章第①段运用的说明方法主要有下定义、作比较和列数字。

B.文中⑤-⑧段运用从主到次的顺序说明了在使用无线路由器时的注意事项。

C.文中加点词语“目前”“极可能”是不能删去的，删去后内容与实际情况不符。

这体现了说明文语言的准确性。
