The early 5G roll-outs are more like a public test than a final product.AT&T,Verizon,and T-Mobile are all using technologies that only travel about 800 feet from a cell site,which means there isn't much coverage.All four carriers are waiting for upgrades()to their base stations that will improve coverage,speed,and reliability.Around the end of this year,AT&T,Verizon,and T-Mobile all intend to launch 5G networks that use the existing 4G spectrum()which will have slower speeds but broader coverage. We've tested AT&T in Dallas and Las Vegas;Sprint in Dallas and New York;Verizon in Chicago,New York,and Providence;and T-Mobile in New York.Every month,we've been seeing better performance and more new devices.It's messy.It's very early days.And if you like new technology,it's very exciting. In previous mobile transformations,we've seen most of the big changes happening years after the first announcement.Take 4G,for instance.The first 4G phones in the US appeared in 2010.But the sorts of 4G applications that changed our world didn'tappear until later.So following that plan,while we're getting a little bit of 5G right now,you should expect the big 5G applications to crop up. 5G stands for fifth-generation cellular(wireless,and the initial standards of it were set at the end of 2017.But a set of standards doesn't mean that all 5G will work the same-or that we even 8

D.By following time order. 答案 D 解析推理判断题。根据第一段中的“He moved to London in 1895 and finished his basic education.Fleming entered the medical field in 1901,studying at St.Mary’s Hospital Medical School.While at St.Mary’s,he won the 1908 gold medal as the top medical student.”,第二段中的“During World War Ⅰ,Fleming served in the Royal Army Medical Corps.”,第三段中的“Returning to St.Mary’s after the war,in 1918...”,第四段中的“In September 1928...”和最后一段中的“Penicillin finally came into use during World War Ⅱ and Fleming won the Nobel Prize in 1945.”可判断出,作者是按时间顺序组织 文章的。故选 D 项。 C The race to 5G is on.All four major US carriers now have some form of 5G wireless,although it’s all limited roll-outs in only a few cities,mostly using expensive phones that won’t support future nationwide 5G network.We’re tracking the roll-outs monthly on our Race to 5G page. The early 5G roll-outs are more like a public test than a final product.AT&T,Verizon,and T-Mobile are all using technologies that only travel about 800 feet from a cell site,which means there isn’t much coverage.All four carriers are waiting for upgrades(升级) to their base stations that will improve coverage,speed,and reliability.Around the end of this year,AT&T,Verizon,and T-Mobile all intend to launch 5G networks that use the existing 4G spectrum(频谱),which will have slower speeds but broader coverage. We’ve tested AT&T in Dallas and Las Vegas;Sprint in Dallas and New York;Verizon in Chicago,New York,and Providence;and T-Mobile in New York.Every month,we’ve been seeing better performance and more new devices.It’s messy.It’s very early days.And if you like new technology,it’s very exciting. In previous mobile transformations,we’ve seen most of the big changes happening years after the first announcement.Take 4G,for instance.The first 4G phones in the US appeared in 2010.But the sorts of 4G applications that changed our world didn’t appear until later.So following that plan,while we’re getting a little bit of 5G right now,you should expect the big 5G applications to crop up. 5G stands for fifth-generation cellular(蜂窝状的) wireless,and the initial standards of it were set at the end of 2017.But a set of standards doesn’t mean that all 5G will work the same—or that we even

A.Initial exploration. B.Great improvement. C.Wide application. D.Extensive promotion. 含案A 解标细节理解题。根据第二段内容,尤其是The early5Grol-outs are more like apublic test than a final product...only travel about 800 feet from a cell site,which means there isn't much coverage.All four carriers are waiting for upgrades to their base stations”和第三段中的It's messy.lIt's very early days.” 可知,目前,美国的5G技术处于开发运用的入门阶段,即初期探索时期,故选A项。 29.Why does the author take 4G for example? A.To persuade carriers to give up 5G. B.To remind people of 4G's importance. C.To prove 5G takes time to make a greater difference D.To show 5G has failed to meet expectations. 含案c 解析推理判断题。根据第四段中的“we've seen most of the big changes happening years after the first announcement,So following that plan..to crop up”可知,作者以4G为例,是为了证明5G会像4G一样, 需要时间来发挥更大的作用,运用于更广泛的领域。 30.What's the author's attitude to 5G? A.Cautious. B.Skeptical. C.Concerned. D.Objective. 答案D 解析观,点态度题。作者在文中客观地介绍了美国5G的现状,并拿4G为例子让人们正确地看待5G, 即现在不要对5G抱太大期待,因为它更广泛的应用要过几年才能出现。由此可推知,作者对5G是抱 着客观的态度的。故选D项。 31.What's the best title for the text? A.Race to 5G B.5G is coming C.How fast is 5G?D.What is 5G? 答案B 解析标题归纳题。通读全文可知,本文主要介绍了美国5G的情况,让人们了解5G的现状以及5G的 前景,5G当下处于初期探索时期,还需要一些时间才能实现更广泛的应用,故B项“5G正在到来”作本 文标题最佳。 D 9
