否定转移的形式与用法
一、动词的否定转移 
1. 形式上否定主句的谓语，实际上是否定从句的谓语 
当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”的主语是第一人称，谓语动词为没有任何副词修饰的一般现在时，它们的否定式实际上是对宾语从句的否定。表示说话者提出一种委婉的看法或主张。如： 
I think that he will help us.——I don’t think that he will help us. 我认为它不会帮助我们。 
I believe that he is right.——I don’t believe that he is right. 我认为他不对。 
I suppose that he likes it.——I don’t suppose that he likes it. 我想他不喜欢它。 
2. 形式上否定谓语动词，实际上否定复合宾语
当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”、“find”的主语是第一人称、谓语动词为没有任何副词修饰的一般现在时，它们前面的否定式实际上是对复合宾语的否定。表示说话者所提出的一种委婉的看法或主张。如： 
I think math difficult. — I don’t think math difficult. 我认为数学不难。 
I find the story interesting. — I don’t find the story interesting. 我认为这个故事没有趣。 
I expect so. —I don’t expect so. 我认为不会。 
注意：动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”在下列情况下，否定不转移： 
（1）这些动词跟其他另一个动词一起做并列谓语时，否定不转移。如： 
I believe and hope he won’t do that. 我相信并且也希望他将不会那样做。 
I feel and admit that we are not foolish. 我觉得并且也承认我们并不愚蠢。 
（2）用于疑问句时，否定不转移。如： 
Do you think it is not going to rain? 你认为天不会下雨吗？ 
Don’t you believe that he has done a good thing? 难道你不相信他做了一件好事？ 
（3）用作插入语时，否定不转移。如： 
Li Lei, I think, won’t be angry with you. 我想李蕾不会生你的气。 
Tom, I suppose, won’t be against it. 我猜想汤姆不会反对。 
Mike, I believe, hasn’t seen the film. 我认为迈克没有看这场电影。 
（4）动词前有其他副词修饰时，否定不转移。如： 
I really don’t think it’s necessary for us to go there now. 我的确不认为我们有必要去那儿。 
I feel strongly that he shouldn’t do such a thing. 我强烈地认为他不应该做那样的事。 
（5）动词为非一般现在时或主语不是第一人称时，否定不转移。 
I thought that he wouldn’t come back soon. 我原以为他不会回来得这么快。

He thinks that he isn’t fit for the job. 他认为他不适合这件工作。 
He doesn’t believe that what we told him is true. 他不相信我们告诉他的事是真的。 
（6）当宾语从句中含的否定为“not……at all”、“not a little”、“not a few”、“not enough”、“can’t help”等固定搭配时，否定不转移。如： 
I think that he doesn’t know it at all. 我想他对那一点也不知道。 
I suppose that it is not enough to remember the words if you want to learn the language well. 我认为如果你想把这门语言学好，那么只记单词是不够的。

（7）当宾语从句中含“no”、“nothing”、“nobody”、“nowhere”、“hardly”、“seldom”、“little”、“few”等否定词或半否词时，否定不转移。如： 
I believe that nothing can make me give it up. 我想任何事情也不能使我放弃。
