　　“二维码”和“扫码重视”可能如今咱们每天都会听到，尤其是走在大街上会有推行某种商品的人说“扫码重视，免费送耳机”等。假如想真正学好英语，但凡咱们常常听到的，提到的，看到的，想到的，都值得思考如何用精确的英语表达出来。今日咱们就来看一下“二维码”和“扫码重视”对应的英语。

　　二维码是二维条码(也叫二维条形码)的简称，英文是two-dimensional barcode。微信上用的二维码叫QR code，属二维条码的一种，它是Quick Response Code的缩写，意思为“迅速呼应码”。

　　dimensional这个词信任咱们不会生疏，咱们常常说的3-D(影片)，即是three-dimensional的缩写。

　　此外，barcode也可写作bar code，意思为“条码”，也叫“条形码”，和二维码不一样，它是一维的。bar是“(长)条”的意思，如“长铁条”是a long iron bar，“一条巧克力”是a bar of chocolate。

　　总结一下：

　　QR code (微信的)二维码

　　scan a QR code to follow 扫码重视

　　0:19"二维码"和"扫码重视"

　　QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached.
