为什么选don't we而不是mustn't we?
一般的动词都是用don't/do we 回答,在这里,have to 虽然和must都是不得不,但have 对应的助动词是do,所以在这里只能用don't we。
而若该句子改为Night has fallen,we must stay here for the night,__就填needn't we.mustn't表示的是禁止。
反义疑问句的题目啊……具体的你可以参照语法书。
陈述部分有have to +v. (had to + v.),疑问部分常用don't +主语(didn't +主语)。
We have to get there at eight tomorrow, don't we?
这些语法是约定俗成的,就像中文里“心里想”,当然不可能是“心”想,而是脑想,记住就可以了
mustn't 不再是助动词形式,他是禁止的意思
没有MUST干吗用它提问呀
和have to 对应
虽然陈述句和简略问句的情态动词或助动词一般要保持一至,但也有特殊情况: Have(进行某一动作)----Don't Have to(不得不)----Don't
