一、如果谓语中有情态动词、助动词或be,直接在它们后面加not构成否定句。 I can dance. 我会跳舞。 I can not dance. 我不会跳舞。 He will go there. 他将在那里。 He will not go there. 他不会在那里。 I am a teacher. 我是教师。 I am not a teacher. 我不是教师。 注意:若谓语中不止一个助动词、情态动词或be时,在第一个后加not。如: He has been to Japan. 他去过日本。 He has not been to Japan. 他没有去过日本。 二、如果谓语中没有情态动词、助动词或be,在动词之前加do not (一般现在时第三人称单数用does not,过去时用 did not,并将原来的谓语动词改为原形) 。 You look well today. 你今天气色很好。 You don’t look well today. 你今天气色不好。 She know what to do. 她知道做什么。 She does not know what to do. 她不知道做什么。 I did morning exercises today. 我今天没做早操。 I didn’t do morning exercises today. 我今天没做早操。 注:have做助动词时,在后面加not;作“有”解时也可以在后面加not;不是作“有”解的为行为动词时,其否定式和其他行为动词一样要在前面加do(does、did) not。如: I have finished my homework. 我已经做完作业了。 I haven’t finished my homework. 我还没有做完作业。 I have a car. 我有一辆汽车。 I have not a car. 我没有汽车。 =I don’t have a car. 我没有汽车。 I have lunch at school. 我在学校吃中饭的。 I don’t have lunch at school. 我不是在学校吃中饭的。 He had lunch yesterday. 他昨天吃了中饭。 He didn’t have lunch yesterday. 他昨天没有吃中饭。 本语法为锐超老师归纳整理,更多细节讲解请报名在线微课堂学习。详情请回复【微课堂】 |
