1、postman的复数形式其实是postmen，将后面的"man"变成"men"就是复数了。postman：名词，邮递员，邮差的意思。
2、常见句型：邮递员给你送来了一个包裹：The postman has brought a parcel for you.今天我们的狗又扑咬了邮递员：Our dog went at the postman again this morning.这条狗咬了邮递员的腿：The dog has nipped the postmen on the leg.
3、词汇搭配：邮递员的投递路线：postman's route；派递邮差：delivery postman；邮差长：Head Postman；邮差包：Postman bag
