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?谢谢!
现在分词作状语中 有having done 的形态啊 如 having done the homewok,I went to play football
追答having 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
