【题目】 Have you heard of 5G? It is the fifth generation of mobile network technology. If the past few years were about testing and developing of 5G technology, it’s time to show some real applications ( 应用) this year. What changes will 5G bring to us?

First, 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. Also, VR games will become more popular with 5G. The short delay of 5G will make the games more real.

This big change will not only make our mobile Internet faster. It will also change every industry like health care in telemedicine and self-driving cars. These cars can send signals to each other. They also “talk” to traffic lights and road sensors (传感器). 5G will show cars to react even faster than human drivers.

5G also makes the Internet of Things (IoT 物联网) possible. IoT is a large network that connects everything to the Internet. Smart homes are part of it. For example, your toaster could automatically ( ) start making breakfast after your alarm rings.

Though 5G makes our lives more convenient, it will not be perfect. For one thing, 5G will not “travel” far. On 4G networks, we can be 10 kilometers away from the nearest transmission base (传输基地) and barely lost signal. But 5G will only cover about 300 meters, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are presently expensive.
