英语语法分析

Lines at the grocery store might become as obsolete as milkmen, if a new tag that seeks to replace bar codes becomes commonplace.

一旦这种新型标签取代条形码并渗入人们生活中，那么杂货店里条形码扫描线可要像送奶工一样“退居二线”了。

Home milk delivery has almost gone extinct in China now, also gone with it are the milkmen, who once delivered bottled fresh milk door-to-door.

如今，送奶到户的服务在中国已经基本上销声匿迹了，同样随之消失的还有送奶工，他们曾经挨家挨户地递送瓶装的新鲜牛奶。
