You'll have to get off here.的句子成分.

问题描述:

You'll have to get off here.的句子成分.
句中的will是助动词?have to 是情态动词?get off是实义动词短语?这三种动词能同时出现?还是我理解错了.

主语You
谓语:will have to get off
状语:here
will have to
有些书说have to是情态动词,但个人觉得不是,因为它有人称和数的变化
在这里will have to类似于must/should的意思,表示命令的.

I will have to go.表示“必须”的.
won't have to=needn't
