反义疑问句中讲“含有think,believe,suppose,imagine,expect等动词后接宾语从句构成的主从复合句
其中有一句:如果主句的时态是过去时等等,疑问句应和主句的人称时态保持一致.
如果主语是第一人称呢?能给一个例子么?
另外must表猜测时,反义疑问句用must后面那个动词开头,那么can't表猜测时,反义疑问句是否也用can't后面那个动词开头呢?
含有think,believe,suppose,imagine,expect等动词后接宾语从句构成的主从复合句,如果主语是第一人称,反义疑问句中根据从句谓语动词形式来使用合适表达.
I think he will come over to help us,won't he?
We don't think it is right to ignore others need,is it?
如果主语是第二三人称,反义疑问句中根据主句谓语动词形式来使用合适表达.
He believes Tom will go for an outing today,doesn't he?
They suppose Jack has finished his omework,don't they?
must表猜测时,反义疑问句:
He must have done his work ,for he is now playing there,hasn't he?
【没有明确表示过去时间的时间状语,用完成时形式】
She must have done her work 【yesterday】,for he is now playing there,didn't she?
【有明确表示过去时间的时间状语,用过去式形式】
He can't do it alone,can he?
祝你开心如意!
