当主句谓语动词是think,believe等动词时,宾语从句的否定意义要放到主句中.

这叫做否定转移,限于否定转移的动词不多,常用的包括think, believe, suppose, imagine, expect等少数几个表示“看法”的动词.否定转移后尽管从句变成肯定形式,但还是要将其视为否定意义,所以下列情况必须要与否定句一致：
1. 用yet不用阿already；用either不用too,用any不用some,等等；如：Idon't believe Mary has finished her work yet.
2. 反意译问句的简略问句要用肯定,如：
I don't inagine he will learn from this lesson, will he?
