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 所以请各位详细说明一下 谢谢啦
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 ...
