do和be动词的区别

因为这是被动式，be+过去分词链带，
is
not
passed
on
=这是不被传递
这个句子所核岩用的is就是be，不改唤御关系动词（be)或者助动词（do）的事儿是因为它是被动所以要用be
用一个的简单的方法去分辨一个句子应不应该是is
or
be
一个句子里没有动词就用be《在正常的句子里，像被动式那些就另当别论了》
eg.
he
is
a
teacher.
他是个老师
she
is
lovely.
她很可爱
一个句子里动词是不可能跟be一起出现的，那就用do
eg。he
doesn't
like
to
eat
ham.
他不是喜欢吃火腿。
like
和eat
是动词
i
don't
feel
well.
我不怎么觉得舒服
fell是动词

do
和be都可以作实意动词和助动词。如果句子中的动词是毕激实意动词,一般用助动词do进行提问,或者变为否定句。助动词do可以构成疑问句、否定句、倒装句、或者强调祈使句。系动词be后跟表语（形容词、作表语的副词、名词、代燃物词、数词、介词短语、分词、不定式、动名词、表语从句等）,

be
