Question

I heard that some patients who had undergone laser eye surgery experienced sudden losses of vision,_____?
A.didn’t I B.hadn’t they C.didn’t they D.isn’t it
为什么选 C

Answer 1

此题考查反意疑问句.陈述部分是宾语从句时
1 主句主语为第一人称（I We）
① 谓语为suppose ,think ,believe ,expect ,imagine ,heard等词,与从句保持一致,并且要注意否定转移
② 谓语为其他动词,与主句保持一致
I suppose father’s sleeping ,isn’t he
I don’t think you are right ,are you
I said that I would come back soon ,didn’t I
2 主句主语为其他人称,与主句保持一致
they think that English is useful,didn,t they?
反意疑问句表示提问人的看法,没有把握,需要对方证实,所以某些主语是第一人称的从句,需要对从句的反意.有些事发生在自己脑子里,别人不能证实,think,image,suppose,believe,heard等都是些自己的信念,看法什么的词,不能问我是这样想的吗?我是这样认为的吗?我听过吗?这只有你自己知道,别人哪知道啊!
