【题目】

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(宽带), low latency(低延时), 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,物联网). 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.

Every single day, our technology seems to shift up a level. Some big companies like Huawei and Samsung have started to deliver. 5G products. 5G technology is becoming reality, It will make some unimagined changes. Let’s wait and see what it brings.

这篇短文主要讲述了5G网即将投入使用，文中讲述了5G网的优点及给人们的生活带来的变化。

【1】细节理解。根据文中“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.” 据《科学日报》报道，预计美国将于2019年开始5G测试，英国将于2020年开始5G测试。中国已经在10个大城市进行了5G测试，并宣布今年开始实施5G。可知，中国、美国和英国预计将在2019年和2020年启动5G。故选A。

【2】段落大意。根据文中“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,物联网). loT connects everyday devices to the Internet.”可知，它可能使许多新的用途是不可能在旧的网络。例如，你可以在3秒内下载一部电影。在4G网络中，这通常需要几分钟的时间。此外，将有足够的容量（容量）供每个人在社交媒体上聊天和在手机上看电影。科学家说，5G将有助于开发自动驾驶汽车和“5G类人机器人”。最重要的是，5G将帮助我们构建物联网（IoT）。可知，主要讲述了5G可能会带来许多新用途。故选A。

【3】细节理解。根据文中“Most importantly, 5G will help us build the Internet of things(IoT,物联网). loT connects everyday devices to the Internet.” 最重要的是，5G将帮助我们构建物联网（IoT）。loT将日常设备连接到互联网。故选C。

【4】推理判断。A. In a picture book在一本图画书里； In a science magazine. 在一本科学杂志上；In a page of sports. 在体育版上； In a book review. 在书评里。通读整篇短文可知，这篇短文主要讲述了5G网即将投入使用，文中讲述了5G网的优点及给人们的生活带来的变化。可知从科技文章中看到。选项B符合题意。故选B。
