什么句子里用be动词
如 I play basketball 和 I am play basketball 什么时候应该加be动词啊?

当然是I play basketball是正确的“我打篮球”,BE动词是play.
一句话中只能有一个BE动词的.
I am play basketball 这句话没法翻译了“我是打篮球”,两个动词,动词是做谓语的.
把play去掉从语法和表达上来说也都是对的,I am basketball,我是篮球
或者把play变成动名词的语也可以正确,
I am playing basketball,我正在打篮球
再问： play不应该是动词吗？怎么会是be动词。play不应该做谓语吗？
再答： BE 动词有三种形式，am is are 这三种。但一句话中只能有一个动词或BE动词做谓语。只能有其一
