看美剧学英语习语：It's on me

Fannie

It's on me: This means that the person speaking will pay the whole amount, used typically when something purchased is shared between two or more people - such as a resturant meal. As in No, you paid for dinner last time - this is my treat.

中文释义：在和朋友一起吃完饭，需要买单时，对方或许会有礼貌地推脱，但是如果你想表明请客的立场，可以使用短语 " It's on me "，意思是“算在我头上；这顿我请”，其中的on代表的是会为...付账（埋单）。该短语既简单又实用，在美剧中出现频次较高。另外也有几个类似意思的表达方式：It's my treat（My treat！）我请客；I'll get the check我来买单；Let me pay the bill 我来付账。
