并且解释一下什么时候用must's she来做,谢谢!
Key: isn't she?
用法讲解:
must与 be 连用,表示猜测、推测,在使用中要注意这个情态动词短语的两个方面。
1、反意疑问句:主语 must be..., be not 主语(代词)?类似的用法还有may be。
eg. They must be late, aren't they?
It may be in your pocket, isn't it?
2、否定句:must be 与may be 的否定形式为 can't be.
eg. They must be late. --(否定)They can't be late
It may be in your pocker. --(否定)It can't be in your pocket.
must 与行为动词连用,在变为反意疑问句的时候,就可以直接使用mustn't 。
eg. He must finish it at once, mustn't he?
is't she?
对BE动进行反意疑问
isn't she?
must在这里只是情态动词,表示可能性很大,但是没有实际意义."她肯定在她房间里,难道不是吗?"所以,真正的动词是be,反意疑问句时,针对be否定就可以了。
isn't she?
真正的动词是be,对be否定就可以了
isn't she ?理由同上
