情态动词变反意疑问句怎么变
情态动词变反意疑问句怎么变
按照反意疑问句的格式,主要注意情态动词肯定与否定的对应:
Must - Needn't
Need - Needn't
Ought to - Oughtn't
Have to - Don't
Will - Won't
Would - Wouldn't
Shall - Shan't
Should - Shouldn't
Must have 表示对过去动作的推测,应该用didn't.
如果是以否定形式开头的句子,变成反意疑问句则相应用肯定形式,也会有一些特殊变化,建议找一本语法书,会有情态动词的用法这一类的.内容不会很多,容易记.
另外,反意疑问句中否定形式一定不能分开写.
