关于be与【过去式：was were 过去分词：been 现在分词：being 第三人称单数：is 】的关系及用法

Question

请不要太书面，阿拉看不懂

Answer 1

be 是动词原形,既可以作系动词构成系表结构;又可以作助动词与现在分词共同构成进行时态,也可以与及物动词的过去分词共同构成被动语态.
be 的现在式:am;is;are. is 是be的第三人称单数 即用在he ,she,it,及其能用he ,she或it 所指代的名词后. 如:I am a student. He is a student. You are a student.
be的过去式:was;were. was是am 和is的过去式 were是 are的过去式 如: I was a student then.
He was a student. You were a student.
be的过去分词:been,可以构成has /have been +名词/形容词 或has /have been +动词的过去分词
be的现在分词:being 可以构成现在进行时的被动语态 am/is/are being done 和过去进行时的被动语态was/were being done
如:She is being punished now.她现在正在被惩罚.
或She was being punished then.她当时正在被惩罚.
