他现在很累为什么是He is tired now.而不是He is being tired now.

问题描述:

他现在很累为什么是He is tired now.而不是He is being tired now.

He is tired now. 是“主语+be+adj.+时间状语”,表示现在的状态。翻译为“他现在很累”。
He is being tired now.句子结构为:be +being +done 是现在进行时的被动语态。
要说一个人很累,是表示一种状态,用一般现在时就可以了,也不必用被动。
仅供参考

He is tired now表状态,tired是形容词不能用于进行时中
