be did do dose 一般都怎么用啊
一些词性比如什么表语啊又什么动词形容词之类的我也不是很明白

这些都是动词.
1.be 是状态动词,它根据主语不同可以变化：
I am a student.
He is a student.
We/You/They are students.
否定句直接在后面加not,也可用省略形式：
I am not a ...
He isn't ...
We aren't ...
疑问句：
Are you a ...
Is he a ...
2.do是原形,does是第三人称单数（he,she,it)形式；did是过去式：
I/we/you/they do homework in the morning.
He/She/Xiao Ming does homework in .
We/THey/You/I/She/He did homework yesterday.
do 还可以是助动词,即帮助主要动词构成否定、疑问和时态等.
I don't know.
He doesn't know.
Did they kow ...
You didn't know ...

did do和dose do的区别 chilren用do还是dose Do you know where he lives?do did dose后面动词不是用原形吗?为什么要用lives加 she has two basketballs.改为一般疑问句时应该用do提问还是dose提问为什么? do did does怎么用? do did does 怎么用? 陈述句变一般疑问句时.do does did怎么区分 do/did/dose、can/could 后面有两个或两个以上的动词时,所有动词都要保持原形吗? 英语中一般疑问句怎么看用什么助动词提问啊?怎么看是用be动词还是do? 疑问词is are dose do 要怎么用?用在那? do you`````和are yuo怎么用,还有is he ````和dose he````` 一般疑问句什么时候用Are,Do,Did,Is提问
