"你是老师，对吧？"英语说成 You are a teacher, aren't you? 这种"前半句陈述 + 后半句反问"就是反义疑问句。
基本规律：前肯后否，前否后肯
- You are a student, aren't you?
- She can swim, can't she?
- He didn't go, did he?
- They won't come, will they?
后半句的助动词/be 动词，跟着前半句的时态和主语走，缩写成否定或肯定。
几个特殊情况
I am 开头：尾巴用 aren't I
- I'm late, aren't I?
祈使句：尾巴用 will you / won't you
- Open the door, will you?
- Let's go, shall we?（Let's 用 shall we）
前半句有 never / hardly / no one：算否定，尾巴用肯定
- He never smokes, does he?
回答看事实，不看问句
- You aren't a teacher, are you?
- 事实是老师：Yes, I am.（不，我是。）
- 事实不是老师：No, I'm not.（对，我不是。）
中文翻译 Yes/No 要按事实倒一下，别按问句翻。
口诀：前肯后否前否后肯，时态主语跟着前半句走；Let's 用 shall we，回答按事实来。
