普遍看法是，他们可以“在一秒钟内下载一部高清电 影”。除此之外，大多数人对5G一无所知。文章主要介 绍除了高速，5G技术还有连接一切、连接的可靠性等 特点。 5.D推理判断题。题千问的是以下哪个可以作为“连 接一切”的例子，由题千关键信息“an example of‘con- necting everything'”可定位到第三段。由该段第二句 "5G would enable one server to connect to multiple terminals and thus establish high-speed coor- dination among them,and help the chips (inside the terminals timely react to meet people's needs" 知，5G将使一台服务器连接多个终端，从而在它们之 间建立高速配合，帮助终端内部的芯片及时做出反 应，满足人们的需求。结合选项可知，D项“同时对所 有成员进行在线测试”符合5G的连接一切的特征，可 以作为5G“连接一切”这个特征的例子。故选D。] 6.B[细节理解题。由题千中的“high safety stand ards”可定位至第四段，由该段第一句“Reliability of connections is...high safety

be used for at least three purposes-connecting everything,reliability of connections,and eliminating delays”可知，根据一个 国际标准化组织3GPP的标准，5G技术至少有三方面 的用途，分别是连接一切、连接的可靠性以及消除延 迟。接着第三段以及第四段分别说明了5G连接一切 和连接的可靠性的特征，由此可推知，作者接下来可 能会讨论的是5G技术能够消除延迟这个特征。故 选A。] 8.A「标题归纳题。文章首段先抛出5G这一话题，紧 接着提到公众对5G技术了解甚少：第二段的第一句 提到除了速度之外5G技术比4G技术有更多优势，紧 接着第三段以及第四段分别介绍了5G技术的具体优 势，由此可知，全文主要是在介绍5G技术的特点不仅 仅是高速。结合选项可知，A项正确。]

[综合性] I.阅读理解 A The Internet plays an important part in many people's daily lives.However,not 方法总结 everyone can get access to it,especially those in poor or remote areas. SpaceX,a US aerospace(航空航天) manufacturer founded in 2002 by Elon Musk,is aiming to bring high-speed In- ternet to people in every corner of the world with the Starlink project. Starlink plans to send nearly 42,000 satellites into low orbit around Earth.Re cently,the 12th batch (of 60 Starlink satellites was launched,bringing the total number of Starlink satellites in orbit to more than 700. During the launch,SpaceX officials gave details about the project's abilities. The satellites have shown "super low la- tency(延迟)and download speeds grea- ter than 100 megabytes per second (mb- ps)",the Verge reported.Its download speed is much faster than broadband currently used in most homes,which can reach about 20 mbps to 30 mbps. 59 选择性必修第四册·(BSD) What makes Starlink's download speed so quick? 间 Rather than sending Internet signals 纠错空间 through electric cables(电缆)，which must be physically laid down to reach dis tant places,satellite Internet works by sending information through the vacuum (真空)of space,where it travels47per cent faster than in fiber-optic(光纤)ca ble. "The latency is low enough to play the fastest online video games and our 4444444444444444444 download speeds are fast enough to stream(释放)multiple(多个)HD mov ies at once,Kate Tice,an engineer at SpaceX,said during the launch broadcast. Though the Starlink project,if suc- cessful,could expand people's access to 方法总结 the Internet,some are concerned.For as- tronomers,the light given off by more satellites in orbit could hinder(阻碍) their view. Also,there are about 1,500 active satellites and 3,000 dead satellites cur- rently orbiting Earth.If too many Starling satellites are sent into orbit,the risk of collision(碰撞)could increase. However,if the Starlink project suc- ceeds,it could“forever alter(改变)the landscape of the telecom industry",CNN reported. 1.What is the aim of the Starlink project? A.To draw people's attention to poor areas. B.To spread the access to the Internet. C.To show people the importance of the Internet. D.To tell people the role SpaceX plays in space technology. ·6 英语兰 2.The author tells readers the advantages of Starlink mainly by A.telling a personal experience B.listing numbers C.analyzing some cases D.quoting experts 3.How does Starlink send Internet sig- nals? A.Through electric cables. B.By using signal towers. C.Through the vacuum of space. D.By using fiber-optic cables. 4.What did CNN think of the Starlink project? A.It is not worth the cost. B.It will achieve its goal soon. C.It might do more harm than good. D.It can be helpful to the telecom in- dustry. B One after another,telecommunica- tions giants(电信巨头)have announced their latest fifth generation (5G)prod- ucts.They have also claimed that 5G technology would be used on a massive scale by 2020.Yet,when reporting about 5G,many domestic media have described it as a“much faster'”technology than4G without mentioning any of its other ad- vantages.As a result,the common public view about 5G is that they could "down- load a HD movie within one second".Be- yond that,most people know nothing about 5G. Actually,5G technology has many more advantages than 4G apart from speed.According to the criteria of 3GPP, an international standardization organization, 巴课时作业 5G technology can be used for at least three purposes-connecting everything,reliability of connections,and eliminating delays. “Connecting everything”is an appro priate slogan(标语)for5 G technology, without which the Internet of Things would be impossible.5G would enable one server to connect to multiple termi- nals(终端)and thus establish high-speed coordination among them,and help the chips(芯片)inside the terminals timely react to meet people's needs.Take auton- omous vehicles for example,they are ma ture technology products.Self-driving cars combine a variety of sensors,such as radar,computer vision,and GPS to iden- tify navigation paths and obstacles.5G technology will link all the elements of a transportation system,such as traffic lights,cameras and,of course,cars to es- tablish perfect coordination so they can avoid obstacles and move on navigation paths,which will help strengthen self- driving technology. Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required. For instance,in certain surgeries,sur- geons insert nano-robots inside a patient's body and have to maintain constant con- trol over the robots to ensure they per- form their functions and do not cause any harm to the patient.This is a technology that can be of great help,as it can estab- lish reliable and continuous connections between the monitor and the nano-ro- bots. ·6 UNIT 12 INNOVATION 5.Which of the following can serve as an example of“connecting everything”? 空 A.Improvement of smart phone sig- nals. 纠错空间 B.Decrease in telecommunication cost. C.High speed in playing computer games. D.Online tests for all members at the same time. 6.Why can 5G be used in the fields with high safety standards? A.It can attract most eyeballs on a massive scale. *41444414444 B.It can provide dependable and con- stant service. C.It offers massive machine types of communication. D.It employs 4G base stations and oc- cupies less space. 7.What will the author most probably 方法总结 discuss in the following paragraph? A.Eliminating delays. B.5G network capacity. C.Disadvantages of 5G. D.Building 5G base stations. 4+:404++40+0+++ 8.What would be the best title for the passage? A.5G Technology:More than about High Speed B.5G Technology Will Shape the Future of Connectivity C.Telecom Giants Work Together to Bet- ter 5G Technology D.Advantages and Disadvantages of 5G Technology and Products Ⅱ.阅读填句 In American history,Benjamin Franklin was famous for his proverbs. Franklin lived in the 1700s.He was a leader of the American Revolution.He was also a scientist,inventor and writer. 选择性必修第四册·(BSD) For many years,Franklin published a book called Poor Richard's Almanack. 间 He introduced many proverbs that he had 纠错空间 heard or created.1 Like this one: "Early to bed and early to rise makes a man healthy,wealthy and wise. Franklin is also remembered for oth- er i proverbs like,"A penny saved is a penny earned.”2 Here are other examples of proverbs that Americans use.3 Some people say,“All is fair in love and war..”They 44444444444444444444 mean that anything you do in a relation- ship or in battle is acceptable.4 In other words,when you are in love with someone,you may refuse to see anything bad about that person. Some people are only interested in having a relationship with someone who is 方法总结 very good-looking.You might tell them that“Beauty is only skin deep.”Your girlfriend may be lovely to look at,but she may also have some bad qualities. 5 Your boyfriend is a wonderful per son,but not good-looking.So what a per- son looks like is not really important. Another proverb is true in love and war or other situations:"Actions speak louder than words."It means that what you do is more important than what you say. A.Or the opposite may be true. B.The first ones are about love. C.Some of them are still used today. D.Another proverb says,“Love is blind.” E.A proverb is a short,well-known say- ing. F.This means that money should not be wasted. G.Another proverb about love is,"Ab- sence makes the heart grow fonder." 6 英语兰 Ⅲ.语法填空 Edison was one of the greatest 1. (invent)that greatly shaped mod- ern society.
