初一否定句-一般疑问句和特殊疑问句讲解

肯定句、否定句、一般疑问句和特殊疑问句的详解

有be 动词（am, is, are ）的句子，

1. 肯定句变否定句：在am, is, are 后面加上not,其余按顺序照抄。 例如：I am a student. → I am not a student. (I am not=I’m not) He is a boy. → He is not a boy. (is not= isn ’t) They are cars. → They are not cars. (are not= aren ’t)

2. 肯定句变一般疑问句：把 am, is, are 提前放到句首并大写 Is, Are,其余照抄，句号变问号。(Am 变为Are ，I 变为you ，We 变为you, My/ Our 变为 your ) 肯定回答 / 否定回答 例如：I am a student. → Are you a student? -Yes, I am./ No, I ’m not. He is a boy. → Is he a boy? -Yes, he is./ No, he isn ’t. They are cars. → Are they cars? -Yes, they are./ No, they aren ’t. We are students. → Are you students? -Yes, we are./ No, we aren ’t. My dad is a teacher. → Is your dad a teacher? -Yes, he is./ No, he isn ’t.

Miss Wang is our English teacher. → Is Miss Wang your English teacher?

(回答时，原句的某人，王老师，爸爸，简，康康等要用人称代词替换。)

-Yes, she is./ No, she isn ’t.

Jane is a good girl. → Is Jane a good student? -Yes, she is./ No, she isn ’t. The dog is his. → Is the dog his? –Yes, it is./ No, it isn ’t. 3.肯定句变特殊疑问句（就划线部分提问）：分3步骤

第一步：先变一般疑问句 第二步：找合适的特殊疑问词代替划线部分

第三步：特殊疑问词提前放到句首，并大写，其余按顺序照抄，省略划线部分。 注意：1.一定先变一般疑问句。但是，如果问的是主语或主语的定语时，语序不变，

为"特殊疑问词(+主语)+陈述句"。 如： Li Ming 's not here.—1.Is Li Ming not here? —2.Is who not here? —3.Who is not

here today? 今天谁没来？

Kangkang is from China. — 1.Is Kangkang from China ? —2.Is Kangkang from where ?—3.Where is Kangkang from? 康康来自于哪里？ It ’s pink . —1.Is it pink ? —2.Is it what color ? —3.What color is it? 它是什么颜色？

没有am, is, are 的句子，含有实义动词

1.肯定句变否定句：在主语后面加上do not 或者does not,其余按顺序照抄，动词

用还原成原形。

三单时用doesn ’t + 动词原形 非三单时用don ’t+动词原形 例如： He has big feet. → He doesn ’t have big feet. 第三人称单数 She knows my dad. → She doesn ’t know my dad. Jane looks like her mom. → Jane doesn ’t look like her mom.

（ 非三单）所有其它人称： I like English. → I don ’t like English. You have two knives. →You don ’t have two knives. We want to buy a cap. → We don ’t want to buy a cap. They have red hair. → They don ’t have red hair. Dogs have four legs. → Dogs don ’t have four legs. 1. 肯定句变一般疑问句：在句首加do 或者does 并大写,其余照抄。注意：动词还原成原形。 三单时借助Does 放句首，句中动词还原为原形 非三单时借助Do 放句首 例如： He has big feet. → -Does he have big feet? ( 肯定回答 / 否定回答:) -Yes, he does./ No, he doesn ’t. She knows my dad. → -Does she know your father ?

-Yes, she does./ No, she doesn ’t. 第三人称单数 Jane looks like her mom. → -Does Jane look like her mom?

-Yes, she does./ No, she doesn ’t. The cat likes fish . → -Does the cat like fish?

-Yes, it does./ No, it doesn ’t. The girl gives a letter to her. → -Does the teacher give a letter to her?

- Yes, she does./ No, she doesn ’t. （ 非三单） 所有其它人称： 肯定回答 / 否定回答

I like English. → Do you like English? -Yes, I do./ No, I don ’t. You have two knives. → Do you have two knives? -Yes, we do./ No, we don ’t. We want to buy a cap. → Do you want to buy a cap? -Yes, we do./ No, we don ’t.
