（2022·陕西宝鸡·一模）Whether frm news reprts r scial media articles, yu may knw that 5G is cming.
5G is the 5th generatin netwrk. It is a new netwrk after 1G, 2G, 3G and 4G. It can cnnect everyne and everything tgether. 5G netwrks will cver many cities in China sn. 5G means super-fast data speed. One can dwnlad a tw-hur mvie fr fewer than 10 secnds, and it is making ur lives mre and mre cnvenient.
5G will make self-driving cars pssible. Fr safety, self-driving cars need super-fast data transmissin (传输) t cmmunicate with their nearby envirnment. 5G is just what makes self-driving cars achieve this. Even airplanes will becme “smart” in the near future. Passengers will be able t use 5G netwrks in the air t cnnect t the Internet and can rder fr fd and drinks.
5G will be a big help fr students wh take nline classes. Many peple live in pr areas in the wrld where there are n schls. But with 5G, this will change. Students all ver the wrld will be able t see places like the Great Wall withut leaving their rms.

These days, bth augmented reality (AR)* and virtual reality(VR)* are still smething new and they are just tys because f their high cst and data usage. Hwever, nt t lng frm nw, 5G will make them much mre cmmn bth at wrk and in ur hmes. Yu might see peple wearing AR glasses r VR headsets* while waiting fr the bus r sitting in the ffice.
One f the mst expected changes will be VR and AR’s influence n the gaming industry. Nwadays, mst VR games are limited when cmpared t the latest cnsle games*. With the pwer f 5G, VR gamers will be able t see, hear, and feel virtual envirnments withut waiting. What’s mre, if yu want t play a game using a VR headset, yu need a machine such as a PC r a gaming cnsle that has a large amunt f strage. This means yu usually have t stay in ne place while playing VR games. The arrival f 5G means we will be able t mve advantages and disadvantages away frm the PC and int the clud s that we nly need a headset. Yu will be able t play VR games anywhere in real time with a headset.
Such headsets and ther 5G wearables will als bring great changes t the wrkplace. In 5G smart factries, fr example, all f the equipment is cnnected t a single netwrk. Wrkers can use 5G headsets when slving prblems. Using AR headsets, they can be infrmed abut a prblem and shwn hw t fix it thrugh a heads-up display.

（2022·陕西宝鸡·一模）If yu lk at the tp f yur phne, yu’ll usually see a little symbl that says 3G r 4G. The “G” stands fr the “generatin” f yur mbile netwrk. But the symbls will becme things f the past after 5G netwrks fully arrive.
Shanghai vice-mayr Wu Qing made the first 5G vide call n a Huawei Mate X Smartphne. Shanghai has als becme the first city in China t start testing 5G netwrks. Abut 100 times faster than 4G netwrks, 5G will let peple dwnlad and uplad data faster than ever befre. But 5G wn’t just bring faster mbile Internet. Peple can use it fr many ther things as well.
Fr example, 5G will help t make self-driving cars safer. Tday’s self-driving test cars have ne prblem-when they fund smething in frnt, that is t late t stp at nce. When the car “sees” smething in frnt, it sends this infrmatin t a data center and receives instructins. Hwever, it will be sme time befre it sends and receives this infrmatin. With this kind f lag(滞后), the cars might crash because they dn’t receive instructin in time. With 5G, this lag will be greatly lwed, making the cars safer.
5G culd als be used t pwer the Internet f Things(IOT), that is, a large nline netwrk that cnnects all things and peple. Fast Internet speeds will be the key t develping this technlgy. The IOT culd be used in a lt f ways. Fr example, with IOT, yur refrigeratr culd autmatically place an rder nline fr eggs when it finds that there are n eggs left inside.

In 1987 a small cmpany named Huawei was started in Shenzhen. After mre than 30 years f develpment, the cmpany has nw beaten Apple and becme the wrld’s secnd largest maker f smartphnes. It has als becme the wrld’s supplier (供应者) f 5G. In China and even in the wrld, Huawei is a wnder. Althugh it started prducing mbile phnes nt many years ag, it has becme ne f the mst famus phne cmpanies.
But recently, Huawei faces sme difficulties. The US gvernment made a law t stp its sales in America. American fficials said Huawei gave infrmatin that it cllected t the Chinese gvernment. At the same time, the US gvernment planned t stp selling parts and services t Huawei. They believed that Huawei’s business wuld be hurt this way.
“We have never received such a request frm the Chinese gvernment and we have never tried t get int ther systems t cllect infrmatin,” Ren Zhengfei, Huawei’s president said. “The law wuld have little effect n ur cmpany. Huawei has enugh ability t deal with the prblems,” Ren added.
In an interview several years ag, Ren Zhengfei said, “I started Huawei with nly £4000 at the beginning, but nw it has becme a 100 billin cmpany. The experience was nt as rmantic as yu imagine.”
Facing the law f the US, Huawei is grwing. Huawei’s smartphne sales arund the wrld rse 50 percent cmpared with a year earlier in the first three mnths f 2019. At the same time, sales frm bth Samsung and Apple fell. S far Huawei has grwn int the wrld’s largest telecmmunicatin equipment supplier (供应商), selling in 170 cuntries.

（2022·广东·秀全中学一模）Sme peple like the freedm f driving their wn cars. But thers find driving t be incnvenient r even dangerus. Frtunately, the driverless cars we've seen in mvies and TV shws are n the way here.
The first driverless car t hit the screen was Herbie, a cute talking car frm the 1968 cmedy The Lve Bug. Herbie culd drive by himself and even talk t his human friends He didn't have any advanced technlgy—just magic.
KITT was anther driverless car that appeared n the 1980s TV shw Knight Rider. KITT used advanced Al t drive itself and help its rider Michael Knight catch criminals.
While the driverless cars f tday can't talk t us, they d have many similarities t the nes we've seen nscreen. Nearly every majr car cmpany is wrking n their wn autnmus, vehicle（AV）. Tesla, fr example. has develped a driver-assistance system fr its cars called Tesla Autpilt.
Tesla Autpilt can cmplete many f the tasks hat human drivers usually d. It can make sure that yur car is centered in the crrect lane, as well as park itself and stp if it thinks that a crash might happen. Hwever, it is nt fully self-driving.
Ggle's sister cmpany Waym seems t be leading the way in the AV area. Its self-driving cars are already being used fr taxi services in the US city f Phenix. It is the nly self-driving car service that perates withut human backup drivers. It uses cmmn cameras as well as laser radar t determine distance, which allws the cars t get arund withut risk f crashing.
Althugh cmpanies are making great prgress in develping AV. there is still a lt f wrk t be dne. Year after year, cmpanies prmise that fully self-driving cars will becme widely available. But nearly all f these prmises have fallen thrugh.
One f the prblems is that designing a self-driving car that is safe and easy t use is much harder than peple realize. Self-driving cars have t analyze millins f data-pints in rder t prevent accidents and chse the crrect rute. Humans are used t ding this—but designing an Al that can wrk like human mind t make a decisin quickly is very difficult.
Hwever, as new technlgies like 5G develp, fully self-driving cars will cme clser t reality.
67．What were Herbie and KITT?
A．They were interesting TV shws.B．They were driverless cars nscreen.
