它包括be动词, do的各种形态，have的各种形态，will等情态动词。

I am watching TV. am 在句子里不能独立做谓语，也没有具体的含义。

二、有的助动词既可以做助动词又可以做行为动词：be动词可以做行为动词,也可以做助动词。

行为动词是有实际意思，表示具体的动作，在句子里能够独立充当句子成分。

助动词是不具有实际意思，在句子里不能独立充当句子成分，只是帮助动词构成各种时态和语态三、学会通过助动词来判断谓语动词，来帮助读懂句子。

1、四类助动词，只有do是包含在谓语动词里的，其它的三个都是在谓语动词前面的。

2、很多助动词既可以做助动词又可以做实意动词。

当做助动词的时候，后面跟动词。

当做行为动词的时候，后面跟名词。

陈述句改为一般疑问句或否定句

一、陈述句改为一般疑问句：1.当句子中含有be动词(am is are was were)或情态动词(can,could,may,might,will,would,must,need,shall,should等）或在完成时态中(has/have/had+过去分词)时，把这些助动词提到句首。

如：①He is a docter.-----Is he a docter? ②They were in the house yesterday.----Were they in……?③Tom can swim.----Can Tom swim? ④He has been to the park.----Has he been to the park? 另外，为符合实际习惯I am/We are..…------Are you…? I was/We were…-----Were you….?I /We can…-----Can you…..? I /We have +过去分词…..------Have you…….?2.当句中含有实义动词时，也就是句子不含上面所提到那些助动词时，必须在句首加DO/Does/Did,具体情况分以下三方面：㈠当句子中含有动词原型时，在句子前加Do, 其中，I+动词。

------Do you…?如：①I like music.---Do you like music? ②They work here.----Do they work here?㈡当句子中含有的动词加S或ES时，即句子是一般现在时，且主语为第三人称单数时，在句子前加Does.如：①He likes music.------Does he like music?②Tom comes from China.-----Does Tom come from China?（注意在此情况下，应把疑问句中的动词变原型。

）㈢当句子中的动词为过去式，在句子前加Did再把动词变原型。

初一英语句型转换陈述句变一般疑问句和否定句

初一英语句型转换陈述句变一般疑问句和否定句1 I can help you. 2 Tom’s T-shirt is five dollars. 3 I often watch TV on Sunday. 一、陈述句变一般疑问句的方法：1．对于助动词、情态动词、be动词作谓语的，动词作谓语的，把把be动词，can，shall， will, may等放在句。

如：首，（some 改成any，my改成your等），句点改成问号。

如：He's a teacher. →Is he a teacher? He c an swim. →Can he swim? He'd like to go there. →Would he like to go there? 2、含有have的一般疑问句,have译为“有”。

一般疑问句式有两种形式: 1.把have/has调到句首。

例如: 陈述句:Tommy has a computer. 一般疑问句:Has Tommy/he a computer? 2.加助动词do/does,第三人称单数用does,其他人称用do，过去式用did。

其句型例如上句可变为: 主语 + have...?例如上句可变为为:Do/Does + 主语Does Tommy have a computer? 3．对于实意动词作谓语的，动词原型借助do，三人称单数借助does，过去式借助did，加在句首，再把谓语改为动词原形，（some 改成any，my改成your等），句点改成问号。

其句型为:Do/Does/did + 主语 + 动词原形+其它如：如：I like him. →Do you like him? He likes me. →Does he like me? I liked him. →Did I like him? 注意：在把肯定句改成否定句或一般疑问句的时候,要注意句中是否有already、some、something、somebody等词，如果有也必须进行改变，already要改成yet，some、something、somebody等分别改成any、anything、anybody等。
