考点名称：否定句

• 否定句：
  表示否定的句子。必须有否定词。
  否定句的构成形式：
  a. 谓语为be动词时，“be+not "一名学生。
  b. 谓语为实义动词而且没有情态动词和助动词时，“do/ does/ did+not"构成否定。 
  例：I do not like dancing. 我不喜欢跳舞。 
        He does not want to go to school. 他不想去上学。
  c. 谓语为“情态动词+实义动词”时，“情态动词+not”构成否定。 
  例：You must not smoke. 你千万不要吸烟。 
         I can not catch it. 我抓不住它。

• 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。
  
  二、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：
