含有think, believe的句子如果表示否定的意義，那么否定要轉(zhuǎn)移到think, believe的前面。如：I don’t think you are right. 我認(rèn)為你不對(duì)。I don’t believe you can do it. 我相信你不能做這件事。
1、主語(yǔ)是第一人稱（I,we)；
2、主句謂語(yǔ)動(dòng)詞是一般現(xiàn)在時(shí)；
3、謂語(yǔ)動(dòng)詞是think,believe,suppose,imagine,expect。
另外，這種結(jié)構(gòu)的反意疑問(wèn)句，疑問(wèn)問(wèn)部分要與從句保持一致。

二、句子的否定轉(zhuǎn)移
