1.must have read 表示:一定是做了某事.表达的是已经存在和发生的事情,而且你的句子里还有long ago,很显然是过去的事情.
2.mustn't you是你必须(干某事)吗?意思不对.
3.当have用作助动词时,就可以用Bhaven't you .如they have finished it,haven't they?

如果没有must 那就选B

这主要跟must have done有关 这是对过去事情的猜测,用这个句型,反问的时候用 didn't 这是规定的,而且做题目的时候多数前面会给一个过去的时间作为标志
当句子侧重强调这个动作,而不是表示猜测的时候使用B,其实跟上面的那个用法很难区分,上面的用法以时间为标志,以这个作为区分吧,另外考试主要考的是上面那种用法...

收起

这道题是一般过去时,因为must 情态动词,所以前面是原型。若想用b 就要把must和long ago去掉,在现在时态才可以。

但是这个呢You must have seen her , ___you ? A mustn't B didn't第二个答案不对的。 must表示推测不可以用mustn't 来反问。 mustn't
