be动词的否定用法
I wasn't answer the phone
I wasn't answering the phone
这两句话语法都对吗
如果都对的话,
再问个很菜的问题，我总是搞不清助动词BE及DO的用法，就是哪种情况下用be，哪种情况下用do,例如：do you speak english 还是are you speak english,do you live here or are you live here

e动词和一般动词否定是不一样的,be动词的否定式是直接在be动词后面加not,一般动词后面不能直接加not,需要借助于助动词do、does、did再加not,助动词后面一定用的是原形动词,如：
I didn't answer the phone.
I wasn't answering the phone.
助动词be与现在分词、过去分词构成进行时和被动语态,助动词do与动词原形,构成一般现在时、一般过去时的否定句、疑问句和倒装结构.如：
Are you eating your lunch?
No,I am not eating my lunch.
Did he do his homework?
He didn't do his homework.
Often does he give me some useful advice.
希望我能帮助你解疑释惑.
