I think he will succeed. 和 I don't think he will succeed. 這類句子的反意疑問句，原則上與從句的主語和謂語相呼應(yīng)，但由于主句的否定式實(shí)際上是否定從句謂語的，所以反意疑問句要用肯定式。如：　　

I think he will succeed, won’t he?

I don't think he will succeed, will he?

主從復(fù)合句的反意疑問句原則上“看主句”。如：　　

She said that I did it, didn't she? 她說是我干的，是嗎？　　

She didn’t say that she liked it, didn't she? 她沒說她喜歡它，是嗎？　　

They know how much it cost, don't they? 他們知道這花了多少錢，是嗎？(　　

但是，當(dāng)陳述部分為I think (believe, suppose) that...等時(shí)。反意問句通常視從句的情況而定(注意否定的轉(zhuǎn)移)。如：　　

I think that he is wrong, isn't he? 我認(rèn)為他錯(cuò)了，是嗎(他錯(cuò)了嗎)?　　

I don't think he likes it, does he? 我認(rèn)為他不喜歡它，是嗎(他喜歡嗎)?　　

I don't suppose he will come, will he? 我想他不會(huì)來了，是嗎?　　

注意，這類用法主要限于主語為第一人稱且think等動(dòng)詞為一般現(xiàn)在時(shí)的情形。
