Print（打?。゛ mobile phone at home. Download（下載）a film in just one second. Control your house from your hand. These are just a few of the technologies（科技）that we may see this year.Lets take a look at a few of them.

在家里打印手機、在一秒鐘內(nèi)下載一部電影、通過你的手控制你的房子……這些都是我們今年可能會看到的先進科技，讓我們了解其中的幾個吧！

Smart screens（智能屏幕）

This year， smart screens will be big news. They use AI technology and look like a tablet（平板電腦）. Google Home Hub is a good example. It is a smart screen that people can use for everything from looking up video recipes（菜譜）to looking at family photos. You can also connect your other smart devices（設(shè)備）to Home Hub through the internet. You can turn on lights or the TV simply by speaking to Home Hub or touching a button（按鈕）on the screen.

今年，智能屏幕將成為大新聞。它們使用人工智能技術(shù)，外形看上去像平板電腦。谷歌的Home Hub就是一個很好的例子，它是一個智能屏幕，從查找視頻菜譜到查看家庭照片，人們都可以使用它來完成。還可以通過互聯(lián)網(wǎng)將其他智能設(shè)備連接到Home Hub，通過與Home Hub對話或觸摸屏幕上的按鈕來打開電燈或電視。

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也將擁有自己的智能屏幕，名為Portal，你可以使用Portal通過視頻與你的朋友和家人聊天。當(dāng)你用手機視頻聊天時，你必須得把手機拿在手里。而Portal有一個可以跟蹤你的攝像頭，你可以把Portal放在桌子上，然后在房間里走動，你的聊天伙伴也能一直看得到你。

5G internet（5G網(wǎng)絡(luò)）

How fast is your mobile phone network（網(wǎng)絡(luò)）？ 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.

你的手機網(wǎng)絡(luò)有多快？在3G和4G之后，5G已經(jīng)在路上了。據(jù)《科學(xué)日報》報道，美國今年將有望測試5G，而英國將在2020年測試5G。中國已經(jīng)在北京和河北的一些地區(qū)測試了5G。

5G is very fast. Its speed is about 10 to 20 times faster than current（現(xiàn)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網(wǎng)速非?？?。它的速度大約是現(xiàn)在網(wǎng)絡(luò)的10倍到20倍。據(jù)新華社報道，你可以在一秒鐘內(nèi)用5G下載一整部電影，這在過去的4G網(wǎng)絡(luò)中則需要幾分鐘的時間。

More importantly， with the help of 5G， we can use the internet of things（IoT， 物聯(lián)網(wǎng)）. IoT connects（連接）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（空調(diào)）while you are on your way back home. All of these things need very fast internet speeds. And 5G is the key.

更重要的是，在5G的協(xié)助下，我們可以使用物聯(lián)網(wǎng)。物聯(lián)網(wǎng)將日常設(shè)備連接到互聯(lián)網(wǎng)上。人們可以利用物聯(lián)網(wǎng)在遙遠的地方控制家里的設(shè)備。例如，在炎熱的夏日，你可以在回家的路上打開家里的空調(diào)。所有這些操作都需要非?？斓幕ヂ?lián)網(wǎng)速度，而5G是關(guān)鍵。

3D metal（金屬）printing（3D金屬打印）

3D printing isnt new. It first came out in the 1990s. But it isnt commonly used in everyday life. 3D printers are expensive， each costing thousands of dollars. In addition， they can only print plastics（塑料）and other basic materials（材料）.

3D打印并不新奇，它最早出現(xiàn)在上世紀(jì)90年代，但它在日常生活中并不常見。3D打印機非常昂貴，每臺都要花費數(shù)千美元。加之，它們只能印刷塑料和其他基本材料。

But now， some 3D printers can print metal. HP can print some small metal parts for cars， such as key rings and gear sticks（操作桿）.

但如今，一些3D打印機可以打印金屬了。惠普3D打印機就可以打印一些小型汽車金屬零件，如鑰匙環(huán)和操作桿。

People can use 3D printing to make things like toys and jewelry（珠寶）. But what if people could print electronic devices（電子設(shè)備）at home？ This would help to save time and money. So more people might think about buying their own 3D printers.

人們可以使用3D打印來制作玩具和珠寶之類的東西。但是如果人們可以在家里打印電子設(shè)備呢？這將有助于節(jié)省時間和金錢，所以更多的人可能會考慮購買一臺屬于自己的3D打印機。
