改否定句怎么改
把肯定句改成否定句分以下情况:
1、句中有be动词的,在be动词后加not。
2,句中有情态动词的(can ,should,must ,would),在情态动词后面加not。
3.句中没有be动词和情态动词的,在动词前加don’t或doesn’t 。
① 句中动词为原形的,加don’t .如: I like apples. I don’t like apples.
②句中动词为三单式的,加doesn’t,并将三单式的动词还原成原形。
如:He likes apples. He doesn’t like apples.
4、肯定句中的some在否定句中应改为any。
如:There are some students in the classroom. There are not any students in the classroom.
形式与用法
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。
