The G stands for the generation （代） of your mobile network. But the symbols will bee things of the past after 5G networks fully arrive. On March 30, Shanghai vicemayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also bee the first city in China to start testing 5G networks. About 100 times faster than 4G networks, 5G will let people download and upload data（數(shù)據(jù)） faster than ever before. But 5G won39。t just bring faster mobile internet. People can use it for many other things as well. For example, 5G will help to make selfdriving cars safer. Today39。s selfdriving test cars have one problemlag（延遲）. When the car sees an obstacle（障礙物）, it sends this information to a data center and receives instructions, However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don39。t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.5G could also be used to power the internet of things （IoT）, that is, a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically （自動(dòng)地） place an order online for eggs when it finds that there are no eggs left inside.（1）Which city was 5G tested for the first time? A.Beijing.B.Shanghai.C.Shenzhen.（2）What can we infer（推測） according to the passage?.

A.5G will help us buy eggs quickly.B.Robots can help us buy eggs online.C.Our refrigerator can order eggs online for us.【答案】 （1）B（2）B（3）A（4）C（5）C 【解析】【分析】短文大意：當(dāng)人們看手機(jī)上方的時(shí)候，會(huì)看到3G或者4G的小符號(hào)。G代表手機(jī)網(wǎng)絡(luò)的代。但是，當(dāng)5G網(wǎng)絡(luò)全面覆蓋時(shí)，這些符號(hào)將會(huì)成為過去時(shí)。3月30日，上海市長吳清第一次使用華為Mate X智能手機(jī)進(jìn)行視頻通話，上海成為中國進(jìn)行第一個(gè)測試5G的城市。5G將會(huì)在很多方面改善人們的生活。 （1）細(xì)節(jié)理解題。根據(jù) Shanghai has also bee the first city in China to start testing 5G networks。可知，上海是中國第一個(gè)進(jìn)行5G測試的城市。故選B。 （2） 推理判斷題。根據(jù)About 100 times faster than 4G networks， 5G will let people download and upload data（數(shù)據(jù)） faster than ever before。 But 5G won39。t just bring faster mobile internet。 People can use it for many other things well?？芍?G的速度將會(huì)是4G的100倍，人們下載或者上傳數(shù)據(jù)都會(huì)快很多。而且，5G不僅僅是在移動(dòng)網(wǎng)絡(luò)上給人們帶來快捷。在其他方面，人們也可以利用5G。由此可以推斷出，5G將會(huì)使人們的生活便利很多。故選B。 （3） 推理判斷題。根據(jù)…With 5G， this lag will be greatly lowered， making the cars safer?？芍?，5G可以大大減少問題延遲，從而使無人駕駛汽車更安全。作者通過這個(gè)例子來告訴我們5G的告訴怎樣起作用的。故選A。 （4）詞義猜測題。根據(jù)5G could also be used to power the internet of things（IoT）， that is， a large online network that connects all things and people。可知，IoT指的是把所有人和物聯(lián)系起來的一個(gè)巨大的在線網(wǎng)絡(luò)。故選C。 （5）細(xì)節(jié)理解題。根據(jù)For example， with IoT， your refrigerator could automatically （自動(dòng)地 ） place an order online for eggs when it finds that there are no eggs left inside?？芍?，當(dāng)冰箱里沒有雞蛋時(shí)，冰箱可以自動(dòng)在網(wǎng)上下單買雞蛋。故選C。 【點(diǎn)評(píng)】此題考查閱讀理解?？陀^信息題可以從文章中直接找到答案。而主觀判斷題考查的是對(duì)文章的感情基調(diào)等，這類題必須經(jīng)過對(duì)作者的態(tài)度、意圖以及對(duì)整篇文章進(jìn)行深一層的推理等。通過語篇邏輯關(guān)系，研究細(xì)節(jié)的暗示，推敲作者的態(tài)度，理解文章的寓義。對(duì)于詞意猜測題。需要準(zhǔn)確無誤地理解上下文，根據(jù)上下文的聯(lián)系進(jìn)行猜測。找出問題答案。6．閱讀下列短文，從每題所給的A、B、C三個(gè)選項(xiàng)中選出最佳答案。 Few students like homework, but it is an important part of middle school life in the UK. The UK has these rules for homework: Grades7and 8 （ages 11 to 13）: 45 to 90 minutes per day。 Grade 9 （ages 14 to 15）:1 to 2 hours a day. Today, many homework tasks are done on a puter. For example, preparing reports, using the Internet or doing online tasks. So schools are usually open before and after normal hours. In this way, students without puters or the Internet at home can use the schools39。 facilities（設(shè)備）. Sometimes, students are given extended learning tasks. That means they need to do more research and analysis（分析）.But however big a task is, teachers always give feedback反饋）to help students find the areas where they can improve. Some schools send students home with home diaries. They advise parents to check on their Children39。s progress. Sadly, not every parent takes much interest.
