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.
It will be als easier fr dctrs t treat patients remtely by 5G. It means caring fr patients frm far away.
The facts listed abve are nly a part f what 5G will make pssible and ppular. Just as in the early days f the Internet in the 1990s, few culd see hw it culd change ur life and the wrld. The same will surely be true f 5G. With 5G, many things d nt seem like dreams any mre. Nw let’s get ready t say gdbye t 4G and welcme the cming f 5G.

Chinese cmpanies lead in glbal 5G patent applicatins with Huawei taking the crwn, accrding t a reprt by IPlytics, an authrized patent data cmpany. Three cmpanies frm China were included in the tp 10 list f 5G Standards-Essential Patents (SEPs) family wners, Huawei ranked first. ZTE Crp and China Academy f Telecmmunicatins Technlgy (CATT) grabbed fifth and ninth places.
Chinese cmpanies tpped the list with mst 5G SEPs applicatins in cmmunicatin systems by the end f April 2019, accunting fr 34 percent f the wrld’s ttal. Chinese tech giant Huawei has taken a leading rle by wning 15 percent f SEPs, accrding t the reprt “Wh Is Leading the 5G Patent Race?”
SG SEPs are patents that any cmpany will have t use when carrying ut 5G and n ne can avid them.
Different frm 3G and 4G technlgies, 5G technlgy will influence varius industries and encurage the appearance f many new prducts, services and industries.
The autmtive sectr will mst likely be ne f the first industries t depend n 5G, which will cnnect vehicles t ther vehicles, radsides, traffic lights buildings and the Internet accrding t the reprt.

39．What des Nicle Peng think f 5G?
A．Varius industries will be helpful fr 5G a lt.B．Many applicatins will make 5G mre advanced.
C．5G will be used by many mst advanced cnsumers.
D．5G will make great prgress in cmmunicatin systems.

（2021·江苏盐城·二模）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 these symbls will becme things f the past after 5G fully arrives.
On March 30th, 2019, Shanghai vice-mayr Wu Qing made the first 5G vide call n a Huawei Mate X smartphne, CGTN reprted. Shanghai has als becme the first city in China t start testing 5G netwrks.
Nw, 4G takes abut 100 t 200 millisecnds t send and receive data. But 5G will get it dwn t 1 millisecnd r less. This big change will nt nly make ur mbile Internet faster. It can be used in many ther ways as well.
Fr example, 5G will help t make self-driving cars safer. Tday’s self-driving test cars have ne prblem—lag. When the car “sees” an bstacle (障碍物), it sends this infrmatin t a data center and receives instructins. Hwever, it takes time t send and receive this infrmatin. With this kind f lag, the cars might crash because they dn’t receive instructins in time. With 5G, this lag will be greatly lwered, making the cars safer, accrding t CNN.
5G culd als be used t pwer the Internet f Things (IOT). This refers t a large nline netwrk that cnnects all things and peple. Fast Internet speeds will be the key t develping this technlgy. Fr example, with IOT under 5G, yur fridge culd autmatically (自动地) place an rder nline fr eggs when it finds that there are n eggs left inside.
All in all, 5G will shape every type f technlgy that it tuches. And yu wn’t have t wait t lng fr that t happen.
