和其他人一起出去吃饭时就会遇到到底谁付账的问题：是请客呢还是AA制呢？今天我们来聊聊英语中关于请客和AA制的表达，下次和老外出去吃饭时就能用上啦！
“请客”怎么说？
A: Let's eat out, shall we?
A: 咱出去吃吧？
B: I'm broke. I've gone through my paycheck for the week already.
B: 俺没钱了，这礼拜的工资都花光了。。。
A: Don't worry about it. It's my treat.
A: 没事啦，我请客。
B: You're sure? You're so generous!
B: 真的吗？你好大方呀！
在这段对话里我们可以注意一下几个表达：
① I'm broke.
Broke 作为形容词可以理解成“破产的，一文不值的”，所以 I'm broke. 就是指“我身无分文”。
② go through
我们知道go through有“经历”的意思，例如：We went through hell while working on this project.（做这个项目的过程中经历了炼狱般的考验）；还能表示“详细检查”：go through the students' papers（批改学生的试卷）。但在对话里它是表示“花光（钱）”。
③ It's my treat.
说到今天的重点了，请客怎么说，这就是最常用的表达之一。同样常用的还有：I will treat you. / It's on me. 此外再给大家介绍一个比较少见的表达：I'll shout you. 它只用于英格兰、澳大利亚和新西兰，所以不要对美国朋友讲哟~~来简单看段对话：
A: Do you want to go out for drinks tonight?
B: No thanks, I'll pass. I don't have any money.
A: Come on! I'll shout you!
B: Shout me?
A: Yeah! It's on me.
基本意思大家都懂了吧，注意一下其中的"I'll pass."是指“这回不去了”。
“AA制”怎么说？
A: Thanks for inviting me out today. I was feeling kind of sad. There's nothing better than grabbing a bite to eat with a good friend to make you feel better.
A: 谢谢你邀请我出来。我正好有些情绪低落，没啥比和好朋友出去吃点东西更能让人振作起来的了。
B: No problem. It's for your birthday, so it's on me.
B: 没事。今天是你生日，所以我请客。
A: Oh, I thought no one remembered, but you don't have to treat me. We can go Dutch.
A: 噢，我还以为没人记得我生日呢。不过不用你请了啦，我们AA制吧。
① to grab a bite to eat
这个短语的意思是“匆忙地、简单吃点什么”，和正式吃顿饭有很大不同。来看段对话帮助理解：
A: I am hungry!
B: So am I, but I only have an hour before my next class.
A: Well, let's grab a bite to eat at that Chinese takeout (外卖).
② go Dutch
严格说来“AA制”有2种：自己付自己吃饭用掉的钱；所有的钱大家平摊。
前者的话在英语里就可以说：go Dutch / Dutch treat，例如：My boyfriend and I always go Dutch.（我和男友吃饭经常是AA制）；The office outing is always a Dutch treat.（办公室的同事一起出去吃饭往往会采用AA制）不过有时大家也不会把到底是平摊还是各付各的分那么清楚，所以在比较随意的情况下，go Dutch / Dutch treat 也能指平摊。
Split the bill，按照字面意思就知道它是指“平摊费用”，例如：Shall we split the bill? 也可以简单说：We'll split. / Let's split. “平摊”还有个说法叫：go halves/halfers，例如：Let's go halves/halfers on lunch today. 不过这种说法对于有些老外来说比较陌生，用split相对比较保险啦。
