小学生英语句型转换的方法总结

小学生英语句型转换的方法总结

一、肯定句改否定句的方法—一步法

1、有be动词的句子，在be动词（am ,is, are ，was, were）后加否定词not。如：is not ，are not ，am not，was not，were not；其中is not=isn’t, are not= aren’t, was not=wasn’t, were not=weren’t, 前者为“完全形式”，后者为“缩略形式”。例如：(1) I am a girl. →I am not a girl. (2)You are a student. →You are not a student. →You aren’t a student. (3)This is Tom’s bag. →This is not Tom’s bag. →This isn’t Tom’s bag.

2、有情态动词can、should、will,would 等，在can，should，will，would 等后加not。如：cannot= can’t，should not=shouldn’t，will not＝won’t；例子：（1）He can swim. →He can’t swim. (2) You should listen carefully in class. →You shouldn’t listen carefully in class. (3) They will put these pictures on the wall near the school gate. →They will not( won’t ) put the pictures on the wall near the school gate.

3、上述都没有的，在动词前加助动词do, does, did的否定形式, 动词还原。如：don’t/doesn’t/didn’t。I like dogs. →I don’t like dogs. He likes cats. →He doesn’t like cats. They watched TV last night. →They didn’t watch TV last night.

4、some 改成any。

5、以动词开头的祈使句，在动词前don’t. 例如：Close your eyes,please. →Don’t close your eyes, please.

二、肯定句改一般疑问句的方法—三步法

1、有be动词的句型，把be动词放在句首，剩下的照抄，（some 改成any，I改成you或we，my/our改成your，）句号改成问号。如：I am in the garden. →Are you in the garden? We are from America. →Are you from America? It is an orange. →Is it an orange?

2、有情态动词的句型，把情态动词can，shall，will等放到句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句号改成问号。如：I can ride the horses. →Can you ride the horses? We will go an join them? →Will you go and join them?

3、上述都没有的，在句首请助动词Do/Does/Did帮忙，剩下的照抄，动词要还原。（some 改成any，I改成you，my改成your，）句号改成问号。注意：句首的第一个字母要大写，句尾标点应为“？”例如：（1）They often play basketball on Sundays. →Do they often play basketball on Sundays? （2）She reads English every morning. →Does she read English every morning?（3）My mother picked a lot of apples last Sunday. →Did your mother pick a lot of apples last Sunday?

4、就一般疑问句回答

一般疑问句有两种回答，即：肯定回答和否定回答。其中，肯定回答用yes 当头回答,否定回答用no当头回答。

三、肯定句改特殊疑问句(对划线部分提问)的方法—四步法

1、根据划线部分确定是什么疑问词。（如what、where、who、whose、how、how many、how old、when 等）

2、接着找be动词或情态动词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。请了助动词帮忙，后面的动词要还原成原形。例如：(1)He is under the tree.(对画线部分提问) →Where is he? (2) We can see some birds in the tree. (对画线部分提问) →What can you see in the tree. (3) I like dogs. (对画线部分提问) →What do you like? ( 请助动词do来帮忙的) （4）He usually gets up at six o’clock . (对画线部分提问) →What time does he usually get up ?(请助动词does来帮忙的) （5）They watched a film in the cinema last night. (对画线部分提问) →Where did they watch a film last night? (请助动词did来帮忙的)

3、把some改成any，my/our改成your, we /I 改成you

4、句号改成问号。
