31、ity (AR)* and virtual reality(VR)* are still something new and they are just toys because of their high cost and data usage. 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

32、 bus or sitting in the office.One of the most expected changes will be VR and ARs 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

33、. Whats 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 a

34、way 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 si

35、ngle 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 Nintendos A

36、R Pokemon Go game, which uses a phones GPS to show Pok 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.20In Pa

37、ragraph 1, we know that _.AIt is common to see people wearing AR glasses nowB5G will make AR and VR technology more popularCVR and AR technologies solved lots of problems in officesDpeople will use AR and VR for games only in bus stations21Why will VR change the gaming industry with the power of 5G?

40、e 6（2021江苏盐城二模） If you look at the top of your phone, youll 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 f

41、irst 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 o

42、ur mobile Internet faster. It can be used in many other ways as well. For example, 5G will help to make self-driving cars safer. Todays self-driving test cars have one problemlag. When the car “sees” an obstacle (障碍物), it sends this information to a data center and receives instructions. However, it

43、 takes time to send and receive this information. With this kind of lag, the cars might crash because they dont 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 t

44、o 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

45、 shape every type of technology that it touches. And you wont have to wait too long for that to happen.24The writer uses self-driving cars as an example to _.Aexplain how self-driving cars workBshow us the advantages of self-driving carsCwarn about the possible dangers of self-driving carsDexplain h

46、ow 5Gs fast speed can be helpful25The underlined word “lag” probably means “_” in Chinese.A延迟B迷路C暂停D耗电26The fridge is mentioned to _.Adescribe the importance of IOTBencourage people to try the new productCintroduce how to use the Internet of ThingsDshow 5G would make IOT more powerful27Which of the

47、following would be the best title of the passage?ACan 5G go any further?B5G has changed our lifeC5G is on the wayDChina is leading the world in 5GPassage 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,

48、the driverless cars weve 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 didnt have any advanced technologyjust magic. KIT

49、T 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.While the driverless cars of today cant talk to us, they do have many similarities to the ones weve seen onscreen. Nearly every major

50、car company is working on their own autonomous, vehicle（AV）. 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, a

51、s well as park itself and stop if it thinks that a crash might happen. However, it is not fully self-driving. Googles sister company Waymo seems to be leading the way in the AV area. Its self-driving cars are already being used for taxi services in the US city of Phoenix. It is the only self-driving

52、 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 AV. there is still a lot of work to be done. Year aft

53、er 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 mill

54、ions of data-points in order to prevent accidents and choose the correct route. Humans are used to doing thisbut 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 reali

56、a short while if necessary30What does It in Paragraph 6 refer to?AThe company of Google.BThe US city of Phoenix.CThe self-driving car serviceDA car with backup drivers.31How might the future of the fully self-driving cars be according to the passage?AIt will be too hard to design a self-driving car

57、that is safe and easy to useBDesigning an Al that can make a decision like human mind is impossible.CFully self-driving cars that are widely used must come to reality years later.DNew 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 o

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. Shangh

59、ai 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 wont just bring faster mobile Internet. People can use it for many other things as well.For example, 5G will h

60、elp to make self-driving cars safer. Todays 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 information to a data center and receives instructions. However, it will be some time before

61、 it sends and receives this information. With this kind of lag(滞后), the cars might crash because they dont 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 conn

For example, with IOT, your refrigerator could automatically place an order online for eggs when it finds that there are no eggs left inside.32According to the pass
