（2022·陕西·长安一中高一期末）5G wireless netwrks are ready t pwer the cities f tmrrw. Hwever, exact implementatin (实施) f 5G will vary frm city t city, with each city having its wn unique set f pririties, requirements, and bjectives.
Since 5G enables cuntless service pssibilities, cities must develp strategies arund their specific needs. Business and civic leaders play a decisive rle in this prcess, helping t drive smart city initiatives and ensuring that key infrastructure (基础设施) elements are in place.
Several urban areas, including Ls Angeles, Dallas, Hustn, Atlanta, and Chicag, are early t benefit frm 5G. Fr peratrs, these large urban centers ffer a critical mass f slid infrastructure t supprt 5G’s cmplex technlgy requirements.
Nw, reginal and lcal gvernments play a critical rle in psitining their cities t becme early 5G adpters. They have a grwing respnsibility t streamline the permitting prcess, change fee structures, and minimize regulatr hurdles in rder t enable greater 5G implementatin.
Effrts are already in full frce by industry players t vercme challenges fr a smth build­ut in areas where 5G is needed first. As business leaders take a mre active rle in ensuring that they are well­psitined t better 5G services, they als increase their ability t transfrm their rganizatins int smart cmpanies. Peter Linder, head f 5G marketing fr Nrth America at Ericssn, emphasizes the critical rle individual leaders can play in making 5G and smart cities a reality.“5G will be intrduced in urban areas first, driven by cnsumer and business’s needs,” he says.“Practive city leaders appreciate the ptential value f 5G fr develping smart city slutins and will partner with service prviders t speed up vital netwrk develpment.”
The rle f business and civic leaders as stimulatrs fr encuraging 5G adptin is decisive t creating smarter, safer, and cleaner cities. The time is right fr urban leaders and business executives (执行官) t wrk tgether tward making smart cities a reality.

（2022·全国·高三）All netwrks like 3G and 4G will be things f the past, because 5G will be reachable in the near future. S, what’s s special abut a 5G future? First f all, its dwnlad speed can be as fast as 20GB/s, which is 100 t 200 times that f 4G. But what’s mre impressive is 5G’S lw delay rate. Nw, 4G takes an average f 200 millisecnds (毫秒) t send and receive infrmatin. But 5G will get it dwn t 1 millisecnd.
5G is a great breakthrugh (突破). It’s ging t change the way equipment cnnects t the Internet, and mre imprtantly, t each ther. And self-driving cars may be ne f the biggest breakthrughs t cme ut f 5G. Human reactin time is 200 millisecnds, yet we still have accidents every day. The self-driving car under a 5G netwrk culd react and cmmunicate its reactin t hundreds f cars arund it, all within 1 millisecnd. It’ll play a great rle in preventing car accidents and ending traffic jams cmpletely.
5G can benefit us in many ther ways. Operatins culd be perfrmed by rbts cntrlled by experts frm the ther side f the wrld. Therefre, mre lives will be saved in time. Factries can be staffed by rbts that can cmmunicate their tasks t each ther, and they can d mre wrk efficiently ver a 5G netwrk. Imagine a grup f drnes (无人机) flying ver a field f crps, using sensrs (传感器) n the grund t srt, pick, feed, and water plants all n their wn. Then farmers wn’t have t wrk s hard anymre.
But, 5G is nt perfect. One majr disadvantage has t d with why it’s s fast. 5G uses the millimeter waves, while 4G uses the 15 t 40 centimeter-lng waves. And shrter waves g fast but nt very far. On 4G netwrks, the signal can g 10 kilmeters. But the 5G signal can g at mst 300 meters, and it can’t even g thrugh walls r rain. S, what des that mean? Having such a shrt signal distance means we need t build a lt f transmitters (信号发射塔) in the future.
5．Hw des the authr shw us 5G’s advantages in Paragraph 1?
A．By giving examples f the uses f 5G.
B．By making cmparisns between 4G and 5G.
C．By explaining the scientific principles f 5G.

（2021·甘肃·民勤县第四中学高三期中）Yur Internet experience is terrible when the net speed is t slw—it takes s lng t pen a web page and the film yu’re watching stps every few minutes. That can be very annying. But it culd be a thing f the past. In the near future, majr telecm carriers will start t prvide 5G services.
What is 5G? What difference will it really make t ur lives? The “G” in “5G” refers t the generatins f mbile netwrk technlgies.
1G let us talk t each ther, 2G let us send messages, 3G gave us mbile data and the Internet, and 4G made all f these things faster. Nw 5G prmises much faster data dwnlad and uplad speeds, and mre stable cnnectins. This means that yu will be able t dwnlad an entire HD mvie in secnds and nly experience a shrt delay between sending and receiving data. Fr example, when yu have a vide chat with yur friend, there is generally a 200 millisecnds delay with 4G, but 5G will reduce the delay t 1 millisecnd, which is almst real time.
5G will be able t imprve many advanced technlgies, such as driverless cars, wearable devices and entertainment. With a 5G netwrk, the shrt delay in infrmatin exchange will allw driverless cars t run mre safely, as they will be able t cmmunicate in real time and avid dangers. Meanwhile, 5G-enabled wearable devices will keep dctrs updated n the health status f their patients, s dctrs can give patients advice immediately if there’s smething wrng. Besides, VR games will becme mre ppular with 5G.The shrt delay f 5G will make the games feel even mre real.
Thugh 5G will make ur lives mre cnvenient, it will nt be perfect. Fr ne thing, 5G will nt “travel” far. On 4G netwrks, yu can be 10 kilmetres away frm the nearest transmissin base and barely lse signals. But 5G will nly cver abut 300 metres, meaning that we will need mre transmitters s that we can get signals. And in rder t use 5G, we will have t buy new prducts specifically designed fr 5G that are currently expensive.
29．What des the “G” in “5G” refer t?
