Answer 2

人称代词： 我 你（们） 他 她 它 我们 他们(她们)
主格：I you he she it we they
宾格：me you him her it us them
主格作主语： I am a boy. You are a girl. He is a student. She is a nurse.
We are Chinese They are red.
宾格作宾语： Look at me. I like them.( I 是主语，them 是宾语）
I am tall. They like me. ( they是主语， me是宾语）
注意：you 有两个意思：你，你们 You are a girl. You are girls.
Be动词 --- be am is are was were being been
be是动词原形，am is are 是现在形式， was were 是过去式 另两个可能你还没见过。
being 现在分词 been 过去分词
它们的用法看主语：主语是上面的七个人称代词是用法如上，背会就行。
其他主语，单数用is，复数用are
This is a book. Tom is a boy.
These are books. Tom and Danny are brothers.
已经是最简单了，多研究几遍，你会懂得。
英语就是背诵，别想得太多，一句一句的背诵。
