浙江省宁波市海曙区2019届初中英语毕业生学业模拟考试试卷
Control your house from your hand. Download(下载)a film in just one second. Print a mobile phone at home. These are just a few technologies that we may see this year. Let's take a look at a few of them.
Smart Screens
This year, smart screens will be big news. They use AI technology and look like an iPad. Google Home Hub is a good example. It is a smart screen that people can use for everything from looking up video recipes(菜谱)to 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 or touching a button(按钮)on the screen.
5G Internet
How fast is your mobile phone network? After 3G and 4G, 5G is on the way. According to Science Daily, it is hoped that the US will test 5G this year, while the UK will do so in 2020. China has already tested 5G in some parts of Beijing and Hebei.
5G is very fast. Its speed is about 10 to 20 times faster than networks now, the BBC noted. You can download a whole film in just one second with 5G. This used to take a few minutes with 4G networks.
3DMetal Printing
3D printing isn't new. It first came out in the 1990s. But it isn't commonly used in everyday l life. 3D printers are expensive, each costing thousands of dollars. In addition, they can only print plastics and other basic materials.
But now, some 3D printers can print metal. HP can print some small metal parts for cars, such as key rings and gear sticks(操作杆). People can use 3D printing to make things like toys. But what if people could print these at home? This would help save time and money. More people might think about buying their own 3D printers.
