问题: 高一英语

A haven't you B didn't you C mustn't you
D mustn' have you

Asell B sells C are sold D is sold
解答:
you must have seen him last night,______?
A haven't you B didn't you C mustn't you
D mustn' have you
虚拟语气的翻译疑问句
如果有具体的表示过去时间状语就要用B
如果没有，如you must have seen him (可以+there等不是表示具体时间的状语，也可以不加)，____?就用A
Books of this kind ___well.
Asell B sells C are sold D is sold
选A 此处sell表示“卖得……”，sell well就是“卖得好”
还有类似的smell badly:（东西）闻起来不好闻，write smoothly（笔等）写起来顺畅等等
books是复数所以用sell不加s
