Question

【题目】 Print a mobile phone at home. Download a film in just one second. Amazing things like these might come true in 2019 as new technology comes into our lives.

Smart screens

This year, smart screens will be big news. They use AI technology. Google Home Hub is a smart screen that people can use for everything such as looking at family photos. You can also connect your other smart devices (设备) to Home Hub through the Internet. You can turn on lights or the TV simply by speaking to Home Hub. Facebook (脸谱网) is also going to have its own smart screen called Portal. With Portal, you can video chat with your friends and family members. What’s more, Portal has a camera that can follow you around. You can just put Portal on a table and walk around the room. Your chat partner will always be able to see you.

5G Internet

How fast is your mobile phone network? After 3G and 4G, 5G is on the way. 5G is very fast. Its speed is about 10 to 20 times faster. You can download a whole film in just one second with 5G. This used to take a few minutes with 4G networks. More importantly, with the help of 5G, we can use the Internet of things (IoT, 物联网). IoT connects everyday devices to the Internet. People can control their devices from far away with IoT. For example, on a hot summer day, you can turn on your air conditioning (空调) while you are on your way back home. All of these things need very fast Internet speeds, and 5G is the key.

3D metal (金属) printing

3D printing isn’t new. It first came out in the 1990s. But it isn’t commonly used in everyday life. 3D printers are expensive, each costing thousands of dollars. And they can only print plastics and other basic materials. But now, some 3D printers can print metal. And people can use 3D printing to make things like toys and jewelry. What’s more, people could print electronic devices at home. This would help to save time and money. So more people might think about buying their own 3D printers.
