否定句的使用方法与分类
否定句表示否定的句子，必须有否定词，那么你对否定句的用法了解多少呢?以下是由学习啦小编整理关于否定句的用法的内容，希望大家喜欢!
否定句的用法
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。
She didn’t believe that he became a good boy. 她不相信它变成了一个好孩子。
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。
I believe that you can’t help singing our national anthem when you win the first place in the Olympic Games. 我相信当你在奥运会上获得第一名时你会情不自禁地唱起国歌来。
(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。
I think that no one can escape if the ship sinks in the sea. 我认为如果这艘船沉入海底的话，那么谁也逃不掉。
I suppose that he is a man of few words. 我猜想他是一个言语不多的人。
二、语的否定转移
有些句子形式上否定谓语动词，实际上是对句子后面状语进行否定。如：

Don’t read in the sun. 不要在阳光下看书。
Don’t talk with your mouth full of food. 不要口里含着食物说话。
