我读被这些词弄糊涂了我知道的关系是
am is are 是BE动词
been是be的过去式
am is are 应该都有过去式吧?are的过去式是were.那用be的句子在过去式就用been?那什么情况用be?什么情况用are am is?
有了am is are 为什么要有BE呢 COPY者不用COPY ,我一定不给最佳答复!

1.am is are 的区别
am只用在I 后面,如 I am a girl 我是女孩
第三人称单数后面跟 is 如 He/She/It/Jim/is
其他跟 are,如 They/we/girls/boys are
2.什么情况下用Be?
借助外加助动词如do,did.或者在情态动词如can,will,would,could,should,may,might之后都必须使用be,而不能直接用am is are.例如,要说He can be a teacher.而不能说 He can is a teacher.同样的,He is a teacher 是正确的说法,He be a teacher 就是错误的说法了.

在完成时要用be动词就要用been
Example:
I have been here since last summer.
I have been interested in it for a long time.
在有情态动词的情况下还要用be动词是就要用到be
Example:
I would be here waiting for you....

某些特定语境下 要用Be
其实主要看口语
