添反义疑问句,为什么?尽量扩充一下关于这两个知识点里没写到的
还有we had to stay at home,(

题目都发错了,学英语的心态很重要哇,建议买一本语法方面的书,语法什么时间都不过时

I don't think you are here, are you?主句是我、我们时,谓语是“想或认为”时,应对从句提问。另要考虑否定的转移。(你原句的know 应是think)
He used to go to work by bus, didn't he.\ usedn't he?
He did not use to go to work by bus, did he?\used he?
We had to stay at home,didn't we?

I do not know you are here ,(are you
He used to go to work by bus ( didn't he)?
he did not used to go to work by bus ,( did he
we had to stay at home,( didn't we
反义疑问句遵循前肯都否的原则.
