英语新闻视频：二维码让你的生活有腔有调

You've probably bought groceries and seen the cashierscan an item to get its price. It works because each product has a code that's a shortcut¹. It prevents the cashier from having to look up each item.

　　你应该买过东西，也应该看过收银员通过扫描商品读取价格，商品上的条码便是读取信息的快捷途径。这样一来，收银员再也不用翻看价目表了。

　　Well, these days new kinds of codes are appearing that are scannable with camera phones. And like a cashier scanner, they create shortcuts² to all kinds of information.

　　现今又出现了能用手机相机扫描的新型码。与收银机的扫描设备一样，通过读取此码就能获得所有信息。

　　This is QR Codes Explained by Common Craft.

　　本期的原来如此介绍的是二维码。

　　In our online world, everything is linked together. You visit a website, and click a link to visit another site, send a message, view a photo or downloada video. A simple click makes everything possible.

　　网络世界里，所有的东西都是连接在一起的。你访问一个网站，点击链接进入另一个网站，发一条信息，浏览图片或是下载视频，所有的操作，只需轻击鼠标即可实现。

　　On the other hand, our physical world is what you see walking down the street. The problem is: nothing is clickable. You can't click a URL on a containerto see recipes. You can't click a statue to read about it on Wikipedia. So, you end up having to type in a link, take notes or just keep walking. But that's starting to change.

　　这就好比现实生活中，你在一条街上边走边看，但问题是：没链接给你点击。你不能在罐头上点击URL查看配方，你也不能点击雕塑在维基百科上查看详情。所以，你得自己输入地址，或记录下来或就此作罢。但现在可不一样了。

　　You may have seen codes like these. They're called QR or "quick response" codes and they mean your camera phone can now be a little like a cashier's scanner.

　　你可能看过这样的码，这叫作“二维码”（QR），有了它们，你手机上的相机便成了收银机似的扫描仪啦。

　　Once you have a QR reader app on your smartphone, you can point your camera phone at these codes and immediately grabuseful information.

　　你的智能手机一旦安装了二维码识别软件，你就可能拿手机对着这些码拍照，即刻获取有用信息。

　　Let's say you're running errands and walk by a sign that says "New Show Coming Soon" and there's a QR code. You can just open your QR reader app, point your camera phone at the code and the app will automatically give you options.

　　比如你外出办点事，遇见一海报写着“新节目即将播出”，旁边印有二维码。你可以打开QR识别软件，给二维码拍照，软件会自动列出选项等你操作。

　　No links to remember, no notes, just point your phone at the QR code and the real world becomes clickable.

　　不用记网址，不用记录信息，只需对准二维码拍照即可，现实世界也有链接啦。

　　But that's just the beginning. Imagine visiting a landmark³ and using a QR code to watch a video about it, or scanning a QR code in a newspaper or magazine to email a link to a friend, or scanning one to follow your local bakeryon Twitter.

　　这还只是冰山一角。想象一下，去某地标游玩，可以用二维码观看相关信息；扫描报纸或杂志上的二维码与朋友分享；通过二维码在推特上寻找当地的面包房。

　　QR codes are important because, for the first time, they make the real world clickable.

　　二维码很重要，因为它开创了现实世界网络化的先河。
