Ⅵ.閱讀理解

• 18．You might have noticed that sometimes，when you're playing mobile games or making a video call，the picture suddenly freezes（卡頓） because the network speed is too slow.When you try to download a movie on your phone，it seems to take forever.
     These annoying things have become things of the past，as China issued commercial licenses（發(fā)放商業(yè)牌照） for 5 G networks on June 6，2019.This means that China's telecommunication（電信） companies are able to offer 5 G network speeds for mobile phone users.
     The "G" stands for generation（代）.1 G let us talk to each other，2 G let us send messages，3 G gave us mobile data and Internet，and 4 G made all of these things faster.So what does 5 G bring？
     First of all，5 G is so fast that it allows us to download an entire HD movie in a second.The delay（延時(shí)） between sending and receiving data is shortened.Now，4 G takes about 100 to 200 milliseconds（毫秒），while humans have a reaction time of about 200 to 300 milliseconds.But 5 G gets the delay down to 1 millisecond or less，which is almost real-time.
     Because of this increase in speed，it is possible to create and use new kinds of technology.Robots will be used to do operations because doctors will be able to control them from somewhere else without any delay.Self-driving cars will be able to drive more safely because they can smoothly communicate with other cars，traffic lights and road sensors（傳感器）.5 G also makes the Internet of Things （IOT，物聯(lián)網(wǎng)） possible.
     All in all，5 G may shape every type of technology that it touches.And you won't have to wait too long for that to happen.
