didn'tyou反义疑问句
反意疑问句中,后面为什么是didn't you,而不是didn't he? -
应该是didn't he 反义疑问句前后主语有一致。正确的是He had to leave the city, didn't he？
这是个反义疑问句，一般疑问句是Did you get there in time?不过，不论是反义疑问句还是一般疑问句，它们的回答是一样的。肯定回答都是Yes , I did.否定回答都是No, I didn't.

有明确的过去时间状语，must表过去推测时，反义疑问句用过去时，即句子中的didn't you?但是，你后面那个句子中，没有过去的时间状语，所以用完成时hasn't he?
对于情态动词加现在完成时的反义疑问句，看时间状语，有现在完成时提示词的，跟完成时走，用have 助动词，对于是过去式时间状语的，跟过去式走，助动词用did
...的反义疑问句是You used to be short,didn't you 对吗? -
正确说法是You used to be short, weren't you?楼主注意了问的时候已经有了be动词be short used to是一个词组表示以前，过去的状态所以的确要用过去时态但要反问的不是一个动作或说动词所以不用do/did/does来问short是个形容词不管是正问反问都要用be动词啊即am is are, aren't是什么。
You have finished your work, havent' you?The train will soon arrive, won't it?He had no money, didn't he? (这里had是实义动词“有”，不是助动词）He had never lived in China, hadn't he? （这句前半部分的had是助动词，帮助表示时态）希望对你理解反义疑问句有所帮助。

1、陈述部分用must(may, might) + have + V-ed表示推测时，若句中带有明显的过去时间的状语，问句部分动词用过去时形式。如：①He might have forgotten his pen in the classroom yesterday, didn’t he?(不用mightn’t he?/ hasn’t he?)②You must have got up late this morning, didn希望你能满意。
didn't you 因为首先前面的句子You said she wouldn't come是一个复合句，而且主句中主语为you而不是I，所以后面的主动词形式要和主句中的主语you一致，根据反义疑问句的规则，前面主句为肯定后面就否定，所以用didn't you 有关反义疑问句的详细知识请看?
