在家里打印手机、在一秒钟内下载一部电影、通过你的手控制你的房子……这些都是我们今年可能会看到的先进科技，让我们了解其中的几个吧！
Smart screens（智能屏幕）
This year， smart screens will be big news. They use AI technology and look like a tablet（平板电脑）. 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.
今年，智能屏幕将成为大新闻。它们使用人工智能技术，外形看上去像平板电脑。谷歌的Home Hub就是一个很好的例子，它是一个智能屏幕，从查找视频菜谱到查看家庭照片，人们都可以使用它来完成。还可以通过互联网将其他智能设备连接到Home Hub，通过与Home Hub对话或触摸屏幕上的按钮来打开电灯或电视。
Facebook is also going to have its own smart screen called Portal. With Portal， you can video chat with your friends and family members. When you do video chats on your mobile phone， you always have to hold your phone in your hand. But 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.
Facebook也将拥有自己的智能屏幕，名为Portal，你可以使用Portal通过视频与你的朋友和家人聊天。当你用手机视频聊天时，你必须得把手机拿在手里。而Portal有一个可以跟踪你的摄像头，你可以把Portal放在桌子上，然后在房间里走动，你的聊天伙伴也能一直看得到你。
5G internet（5G网络）
How fast is your mobile phone network（网络）？ 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.
你的手机网络有多快？在3G和4G之后，5G已经在路上了。据《科学日报》报道，美国今年将有望测试5G，而英国将在2020年测试5G。中国已经在北京和河北的一些地区测试了5G。
5G is very fast. Its speed is about 10 to 20 times faster than current（现在的）networks. You can download a whole film in just one second with 5G， according to Xinhua. This used to take a few minutes with 4G networks.
5G网速非常快。它的速度大约是现在网络的10倍到20倍。据新华社报道，你可以在一秒钟内用5G下载一整部电影，这在过去的4G网络中则需要几分钟的时间。
More importantly， with the help of 5G， we can use the internet of things（IoT， 物联网）. IoT connects（连接）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.
