问题描述:

he vicar has been asked to have the tree cut down,but so far he has refused.
1:上句中:has been asked to...是被动语态吧?
2:have the tree cut down,为什么要加个have,个人觉得这样不就可以了吗?-------cut down the )

1.Yes,是被动语态
2.have sth. done是个固定搭配,意思是“使某物被……”
改成cut down the tree语法上是对的,不过意思有点改变
原句砍树的人不知道是谁,而改后的句子砍树人很可能就是指his vicar了

1.是被动
2.have sth.done是一个句型,表示使sth.被怎么样的意思.这里注意的 是cut是个过去分词的形式,不是原型!
