___more attention,the tree could have grown have grown better.

问题描述:

___more attention,the tree could have grown have grown better.
A given B to give C giving D having given 答案是A这道题还原成完整句应该是if the tree had been given more attention,the tree could have grown better 那是不是改成Having been given more attention,.更好点呢?

A Given 是对的.你说得没错,还原成完整句应该If it had been given more attention,the tree could have grown better .但不能改为Having been given more attention,非真实条件句,当从句的主语与主句的主语相同时,...现在分词作状语中 有having done 的形态啊 如having done the homewok,I went to play footballhaving done的形式,只用在时间状语从句中。如你的这句: having done the homewok,I went to play football【俊狼猎英】团队为您解答。祝你进步。请尽快采纳。
