Question

The goods you shipped against our order NO.121 is better than ...请问这句的against该怎么理解?用在这句是否恰当?期待你的及时解答,

Answer 1

against有几个解释,是
1、以…为交换条件,以…为交换对象,用…交换,以…报答：
to trade one thing against another以物易物
2、以…为标准；根据：
I checked my watch against GMT.我以格林尼治时间对表.
这两个可以解释句子中against our order NO.121 ,就是“依照121号订单”的意思
