小学英语所有句型转换的方法 一般疑问句, 就是将一般疑问词提到句首。 没有一般疑问次(am is are)就加上助动词放在句首。 然后句子中间注意要改变的地方。 比如说,如果是一句以第三人称来写的陈述句。 那一些动词后面会加上es。 如果要改成一般疑问句, 句子里面又必须将助动词does(第三人称单数)放在句首作一般疑问句的话,那改变的时候,动词后面就必须去es。 然后就是some和any的事情, 陈述句用some, 一般疑问句用any。 但是一小部分一般疑问句里面, 看到some, 一般疑问句也是要改some的。 在这句句子是…… 比如说想要什么东西, 一般疑问句里面就要用some。 还有一种是特殊疑问句, 题目一般是划线提问。 根据划线的词语选用特殊疑问词, 放在句首, 进行提问。 特殊疑问词一般是w或wh开头的。 如: what \\how\\ who\\ how many \\how much \\what colour\\ how old\\which\\why…… 等等…… 一、 肯定句改否定句的方法——一步法 1、 在be动词后加not。如:is not , are not , am not, was not, were not; 2、 在can,should, will等后加not。如:cannot, should not, will not; 3、 上述都没有的,在动词前加助动词否定形式don’t/doesn’t/didn’t。 4、 some 改成any。 二、 肯定句改一般疑问句的方法——三步法 1、 把be动词放在句首,剩下的照抄,(some 改成any,my改成your等)句点改成问号。 2、 把can,shall, will等放到句首,剩下的照抄,(some 改成any,my改成your等)句点改成问号。 3、 上述都没有的,在句首请助动词Do/Does/Did帮忙,剩下的照抄,(some 改成any,my改成your等)句点改成问号。 三、 肯定句改特殊疑问句的方法——四步法 1、在一般疑问句的基础上,句首添加一个疑问词即可,可根据划线部分确定是什么疑问词。 2、接着找be动词或can,shall, will等放在疑问词后面,若没有则请助动词do/does/did帮忙,写在疑问词后面,how many除外,必须先写物品,再写be动词等。 3、划线部分去掉后剩下的内容照抄,(some 改成any,my改成your等) 4、句点改成问号。

一.肯定句变成否定句 如果句中有be动词is,am,are 或情态动词must,can等,在其后面直接加not, she is your mother. she isn't your mother 2.如果没有be动词或情态动词,加don't,does't或did't she likes playing football. she doesn't like playing football.二.肯定句变成疑问句 变成一般疑问句如果有be或情态动词动词就把他们提前, she is your mother. Is she your mother? 2.如果没有就在前面加do的某种形式,第三人称用does,过去时用did she likes playing football. Does she like playing football? 变成特殊疑问句, 要具体分析,看是对什么进行提问,简单来说, 1.对人提问用who, she is your sister.Who is your sister? 2.对事物用what, The book is on the desk. what it is on the desk? 3对时间用when, She will come back tomorrow.

肯定句改否定句可大致分为三类:1.有be动词或者情态动词的肯定句变否定句2.没有be动词也没有情态动词,有实意动词(表示动作的动词)的肯定句变否定句3.含有动词have/has的肯定句变否定句以下对上述三种肯定句变否定句的变化规则依次讲解1.有be动词或者情态动词的肯定句变否定句转变方法:在be动词或情态动词后面直接加not例1. I am a student. → Iam nota student.例2. You are sad. → Youare not sad.例3. I can swim. → Ican notswim.例4. You will go to the park.→ Youwill notgo to the park.2.没有be动词也没有情态动词,有实意动词(表示动作的动词)的肯定句变否定句转变方法:借助助动词(do, does, did)来帮助否定①当句中的动词是原形时,加don't。例1.I like English.→ I do not like English.例2.You have dinner.→ You do not have dinner.②当句中的动词是第三人称单数时,加doesn't ,再加动词原形。例1. She likes singing.→She doesn't like singing.例2. She does her homework.→ She does not do her homework.③当句中的动词是过去式时,用didn't,加动词原形例: We had a great time during our holidays.→We did not have a great time during our holidays.3. 动词have/has的特殊说明:①当have表示“某人有什么的时候”,其否定形式为have not/has not例: She has two books.→ She has not two books.②当have作为实意动词时,其否定形式为 do not have/does not have例: You have dinner.→You do not have dinner.③当have在完成时中作为助动词时,其否定形式为have not/has not例: I have seen this film.→ I have not seen this film.4. 一些特殊说明:①肯定陈述句中的some/too,在否定陈述句中应改为any/either。例1.He has some milk.→ He hasn’t any milk.例2.

She has not books,either.②肯定陈述句中若有and连接两个并列的成分,在否定陈述句中通常应改为or。例: There are students and teachers in the classroom.→There are not students or teachers in the classroom.但以下几种状况,不需要改为orA. 句子中出现两个否定词。如: Men cannot live without air and water.B. and列举的成份前都有否定词。如: It has no eyes and no ears.C. and列举的成份在否定词前面。如: Tom and Merry can not write their names.D. and构成的固定词组。如: He did not work day and night.E. and连接两个表示先后发生的动作。如: Don't drink and drive.
