英语 you must have read this book, didn't you 为什么用didn't
you must have read this book, didn't you
为什么用didn't,而不是mustn't you?
haven't you?
don't you?
有mustn't you的说法吗?

have read 中,read是过去分词（read-read-read）
是过去完成时
首先排除mustn't you?mustn't 只能表禁止
don't you?时态不对
这里must表示猜测,这时反意疑问句问must后面的部分.
You must have done that,haven't you?
haven't you?也可以
