核心句型：
Your last shipment wasn't up to scratch.
你上次送去的货不合格。
up to scratch 这个习惯用语起源于九十多年前在室外举行拳击赛的时代。当时人们在泥地拳击场上划出一条线，就叫做scratch，而两名拳击选手在准备开始比赛的那一刻得用脚尖抵着这条线面对面站着，这样才合乎比赛规定。现在人们把这个习语应用到与拳击无关的地方，表示：“合乎标准，达到标准”。因此，当美国人说"Your last shipment wasn't up to scratch."时，他/她要表达的意思就是:"Your last shipment wasn't up to par."、"Your last shipment didn't meet the standards."。
