be not是系动词的否定,用于主系表结构,后面接形容词或者名词；
do not是动词的否定,用于主谓宾结构,后面接动词原型；或者疑问句,
比如：Don't you think so?
not````是不想缩写了就写出来的
smoking那个嘛`这个是被动语态,吸烟是被禁止而不是主动禁止,其实是smoking isn't allowed by sb`,省略后面的,翻译是禁止吸烟.
被动语态和这些情况差不多,就是强调一个“被”字,基本结构式be done.

比如
I don't want to go to school today.
I'm not happy.
It isn't your fault.
don't 后面一般接动词
not 后接形容词和名词
isn't不就是be动词加not吗
其实就是do后面接动词，be后面接名词或形容词
这样说其实没什么意义，你还是多读些句子慢慢体会...
