关于现在分词的完成式
现在分词的被动形式:being+动词过去分词
现在分词的完成形式:having+动词过去分词
现在分词完成式的被动式:having been+动词过去分词
这样我就想问几个问题.首先
现在分词的完成形式与Have/has+动词过去分词有什么区别??能不能给个例句对比下(最好有中文翻译)
还有Having been shown around the school, we had a rest.这句话我想用的应该是现在分词完成式的被动式.是以前发生的.既然是以前发生的为什么要用现在分词的完成式?也就是为什么要用having.
其实我关键就是不明白.现在分词的完成式到底是怎么回事.因为我是这么想的.现在分词一般都是现在正在进行的.而完成是过去..这两个放一起.很晕!~希望有人能给我解释下哈,谢谢大家~
参考答案:现在分词的完成式主要用在状语中，表示这个动作在谓语所表示的动作之前完成。
【例如】
Having succeeded in the last examination, she was more confident of another success in the coming one. 已经在上次的考试中成功,她对即将到来的考试有成功的信心!
Having found the cause, they were able to propose a remedy.找到了原因,他们能够准备救助措施.
Having finished his homework, the boy went to play computer game.完成了家庭作业后,男孩去玩电脑游戏了.
Not havings made adequate preparations, they thought it better to postpone the excursion till next week.
没有作好充分地准备,他们认为最好把旅行延期至下周.
独立结构中也可以用现在分词的完成形式。
【例如】
His parents having died, the orphan is now taken care of by the government.他的父母去世了,这个孤儿现在由政府照料.
The guests having left, they resumed their discussion.客人们走了,他们恢复(继续)了他们的讨论.
