I don’t think he has finished his work yet,_________?(反义疑问句)
I don’t think he has finished his work yet,_________?(反义疑问句)
答案是;has he
反意疑问句中,陈述部分是宾语从句,主句的主语是第一人称,谓语是think,suppose,believe,suspect,imagine等时,其疑问部分与宾语从句相对应构成反意疑问句.如:
I think he is right,isn't he?
若主语不是第一人称,其疑问部分与主句相对应构成反意疑问句.如:
He thought they were wrong,didn't he?
否定前置时,如:I don't think he is right,is he?陈述部分相当于 I think he is not right 所以,疑问部分用肯定结构,是 is he?
本题中,首先主句是第一人称,谓语动词是think,所以,疑问部分与从句相对应;从句是现在完成时,疑问部分要用现在完成时的助动词has提问;又由于是否定前置,相当于陈述部分是否定,所以疑问部分是肯定.因此,答案是:has he?
