【題目】

How fast might your mobile phone network be in the future? After 3G and 4G, 5G is on the way. 5G (from “the fifth-generation mobile networks”) is the latest generation of mobile communications, including extreme high bandwidth(寬帶), low latency(低延時(shí)), and high density(高密度) connections. According to Science Daily, 5G tests are expected to start in 2019 in the US and by 2020 in the UK. China has already tested 5G in10 big cities and announced the start of 5G this year.

As a result of the increased size of networks, data transfer will be much faster and more reliable.5G is expected to be 10 to 100 times faster than the average speed of the current 4G network. It may enable many new uses that are impossible on older networks. For example, you can download a film within just 3 seconds. This used to take a few minutes with a 4G network. In addition, there will be enough capacity(容量) for everyone to chat on social media and watch movies on their phones. Scientists say 5G will help the development of self-driving cars and the “5G man-like robot”as well. Most importantly, 5G will help us build the Internet of things(IoT,物聯(lián)網(wǎng)). loT connects everyday devices to the Internet. People can control their devices remotely. For example, on a hot summer’s day, you could tum on your air conditioning with loT before you go home. All of these things need very fast Internet speeds.5G will be the key.

China has already tested 5G in10 big cities and announced the start of 5G this year.” 據(jù)《科學(xué)日?qǐng)?bào)》報(bào)道,預(yù)計(jì)美國(guó)將于2019年開(kāi)始5G測(cè)試,英國(guó)將于2020年開(kāi)始5G測(cè)試。中國(guó)已經(jīng)在10個(gè)大城市進(jìn)行了5G測(cè)試,并宣布今年開(kāi)始實(shí)施5G?芍,中國(guó)、美國(guó)和英國(guó)預(yù)計(jì)將在2019年和2020年啟動(dòng)5G。故選A。

Most importantly, 5G will help us build the Internet of things(IoT,物聯(lián)網(wǎng)). loT connects everyday devices to the Internet.”可知,它可能使許多新的用途是不可能在舊的網(wǎng)絡(luò)。例如,你可以在3秒內(nèi)下載一部電影。在4G網(wǎng)絡(luò)中,這通常需要幾分鐘的時(shí)間。此外,將有足夠的容量(容量)供每個(gè)人在社交媒體上聊天和在手機(jī)上看電影?茖W(xué)家說(shuō),5G將有助于開(kāi)發(fā)自動(dòng)駕駛汽車和“5G類人機(jī)器人。最重要的是,5G將幫助我們構(gòu)建物聯(lián)網(wǎng)(IoT)?芍饕v述了5G可能會(huì)帶來(lái)許多新用途。故選A

3細(xì)節(jié)理解。根據(jù)文中“Most importantly, 5G will help us build the Internet of things(IoT,物聯(lián)網(wǎng)). loT connects everyday devices to the Internet.” 最重要的是,5G將幫助我們構(gòu)建物聯(lián)網(wǎng)(IoT)。loT將日常設(shè)備連接到互聯(lián)網(wǎng)。故選C。
