Question

【題目】

If you look at the top of your phone，you'll usually see a little symbol that says 3G or4G． The"G"stands for the"generation"of your mobile network．But these symbols will become things of the past after 5G fully arrives．

On March 30th，2019，Shanghai vice﹣mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone，CGTN reported．Shanghai has also become the first city in China to start testing 5G networks．

Now，4G takes about 100 to 200 milliseconds（毫秒）to send and receive data（數(shù)據(jù)）．But 5G will get it down to 1 millisecond or less．This big change will not only make our mobile Internet faster．It can be used in many other ways as well．

For example，5G will help to make self﹣driving cars safer．Today's self﹣driving test cars have one problem﹣lag．When the car"sees"an obstacle（障礙物），it sends this information to a data center and receives instructions．However，it takes time to send and receive this information．With this kind of lag，the cars might crash（撞擊）because they don't receive instructions in time．With 5G，this lag will be greatly lowered，making the cars safer，according to CNN．

5G could also be used to power the Internet of Things（IOT）．This refers to a large online network that connects all things and people．Fast Internet speeds will be the key to developing this technology．For example，with IOT under 5G，your refrigerator could automatically（自動(dòng)地）place an order online for eggs when it finds that there are no eggs left inside．

All in all，5G will shape every type of technology that it touches．And you won't have to wait too long for that to happen．

【1】From Paragraph ②，we can know that　 　．

A. 5G is widely used in ShanghaiB. it took lots of efforts to test 5G

C. China is working on its 5G networksD. 5G would make it possible to take videos

【2】Compared with 4G，5G could be　 　．

A. cheaperB. fasterC. saferD. busier

【3】The underlined word"lag"probably means"　 　"in Chinese．

A. 延遲B. 迷路C. 暫停D. 耗電

【4】The refrigerator is mentioned to　 　．

A. describe the importance of IOTB. encourage people to try the new product

C. introduce how to use the Internet of ThingsD. show 5G would make IOT more powerful

【5】Which of the following would be the best title of the passage？　 　

A. Can 5G Go Far？B. How is 5G Changing Our Life？

C. 5G is on the WayD. China is Leading the World in 5G

【解析】

本篇文章難度適中，主要講述5G時(shí)代已經(jīng)到來，并且講述5G與以前比較，它的速度更加快以及講述5G的用途。

【1】推理判斷題。根據(jù)On March 30th，2019，Shanghai vice﹣mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone，CGTN reported．Shanghai has also become the first city in China to start testing 5G networks“2019年3月30日，上海副市長吳青用MateX智能手機(jī)打了第一個(gè)5G電話，CGTN報(bào)道，上海已經(jīng)成為中國開始測試5G網(wǎng)絡(luò)的第一個(gè)城市”可知，本段主要介紹了上海已經(jīng)開始測試5G網(wǎng)絡(luò)，即中國已經(jīng)開始致力于自己的5G網(wǎng)絡(luò)．故選C。

【2】細(xì)節(jié)理解題。根據(jù)Now，4G takes about 100 to 200 milliseconds（毫秒）to send and receive data（數(shù)據(jù)）．But 5G will get it down to 1 millisecond or less“現(xiàn)在，4G傳送和接收數(shù)據(jù)需要大約100﹣200毫秒．但是5G將降低至1毫秒甚至更短”可知，與4G相比，5G更快，故選B。

【3】詞義猜測題。根據(jù)When the car"sees"an obstacle（障礙物），it sends this information to a data center and receives instructions．However，it takes time to send and receive this information．With this kind of lag，the cars might crash（撞擊）because they don't receive instructions in time“當(dāng)汽車遇到障礙物時(shí)，它發(fā)送這個(gè)信息到數(shù)據(jù)中心并且接收指令．然而，傳送和接收信息需要時(shí)間．汽車可能會撞因?yàn)樗麄儧]有及時(shí)接收信息”可知，lag意為延遲．故選A。

【4】推理判斷題，to表示目的，題目意為文中提到冰箱是為了……。根據(jù)5G could also be used to power the Internet of Things（IOT）“5G也可以被用于推動(dòng)物聯(lián)網(wǎng)”可知，為了顯示5G對物聯(lián)網(wǎng)更有影響力，故選D。

【5】主旨大意題。根據(jù)All in all，5G will shape every type of technology that it touches．And you won't have to wait too long for that to happen“總而言之，5G將會影響涉及科技的每個(gè)領(lǐng)域，你不會等太久的，它會發(fā)生的”可知，5G正在路上。故選C。

解答詞義猜測題時(shí)，可以使用如下技巧：1、根據(jù)上下文來猜測詞義；2、通過同義詞或近義詞來猜測詞義；3、通過構(gòu)詞法來猜測詞義；4、通過定義或釋義來猜測詞義；5、通過句法功能來猜測詞義；6、通過轉(zhuǎn)折和因果關(guān)系來猜測詞義；7. 通過生活常識來猜測詞義。對于這類題采取“代入法”也非常有效，即將備選答案逐一代入文中，哪一個(gè)選項(xiàng)能使句子的意思通順、連貫，且與上下文的內(nèi)容一致，哪一個(gè)選項(xiàng)就是該題的正確答案。

例如第3題。根據(jù)When the car"sees"an obstacle（障礙物），it sends this information to a data center and receives instructions．However，it takes time to send and receive this information．With this kind of lag，the cars might crash（撞擊）because they don't receive instructions in time“當(dāng)汽車遇到障礙物時(shí)，它發(fā)送這個(gè)信息到數(shù)據(jù)中心并且接收指令．然而，傳送和接收信息需要時(shí)間．汽車可能會撞因?yàn)樗麄儧]有及時(shí)接收信息”可知，lag意為延遲．故選A。
