All big cities are quite similar. Living in a modern Asian city is not very different from living in an American city. But it is different from living on farms however.

In many parts of the world, farmers and their families live in villages or towns. In the United States, however, each family lives on its own fields and often can't see any neighbor. Instead of traveling from a village to the fields every morning. American farmers stay on their land all the week. They travel to the nearest town on Saturdays for shopping or on Sundays for church. The children ride on horses to large schools which serve all of the farm families living in the area. In some areas there are some small schools serving a few families and the children walk to school.

Of course, life keeps changing for everyone including farmers. Today there are cars, good roads, radios and TV sets. And of course, there are modern machines for faming now. All these have greatly changed farmers’ life.

Before, farming in America was often a lonely way of living for a long time. Farmers had to deal with their own problems, instead of getting help from others. They learned to try new ways, and thought of their own ideas instead of following old ways.

You might have noticed that sometimes, when you’re playing mobile games or taking a video call, the picture suddenly freezes because the network speed is too ________. When you try to download a movie on your phone, it seems to take forever.

These annoying things will soon become a thing of the ________, as China just issued commercial licenses (发放商用牌照) for 5G networks on June 6, 2019. This means that China’s telecommunications (电信) companies will be able to offer 5G network speeds for mobile phone users.

The “G” in “5G” ________ generation (of mobile network technology). 1G let us talk to each other. 2G let us send messages. 3G gave us mobile data and internet, and 4G made all of these things faster. So what will 5G bring?

First of all, 5G is so fast that it will allow you to download an entire HD movie in seconds. The delay between sending and receiving data will be shortened. Now 4G takes about 100 to 200 milliseconds (毫秒), while humans have a reaction time of about 200 to 300 milliseconds. But 5G will get the delay down to 1 millisecond or less, which is almost real-time.

Because of this ________ in speed, it will be 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 run more ________ because they can smoothly communicate with each other, traffic lights and road sensors (传感器).

5G also makes the internet of things (IoT, 物联网) possible. IoT is a large network that connects nearly everything. ________, your toaster might be able to automatically start making your breakfast after your alarm clock rings.

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.
