two-by-fours
问题描述：
two-by-fours
原文：My frustration was exacerbated when I realized that many of my fellow Home Depot shoppers,some of whom had seemed to me to have the intellectual capacity of the two-by-fours they were buying,were effortlessly tackling and successfully completing projects far more complex than mine.
答
two-by-four 这里虽没说单位,不过,去建材商店买木材的朋友,应该知道,木材是以多宽和多厚为规格的,因此这里不可能是英尺,而是
4英寸宽 x 2英寸厚
我们中文一说表达是 2 x 4 寸方材
一楼朋友的思路正确,只是单位给错了,没有说几尺的,长度才以尺为单位吧,不过,在美国,一般以码为长度单位
