过去分词与现在分词被动式的区别

问题描述:

过去分词与现在分词被动式的区别

过去分词在被动的同时,还表示完成,而现在分词被动式在被动的同时,还表进行.
Built in 1501,the bridge is over 500 years old.这座桥建于1501年,已有五百多年的历史.
Who is the woman being operated on?正在动手术的女人是谁?
但有时它们也可表示相同的意思.如:
Written in haste,the book has many mistakes.这书因写得仓促,所以错误不少.
Being written in haste,the book has many mistakes.这书因写得仓促,所以错误不少.
Having been written in haste,the book has many mistakes.这书因写得仓促,所以错误不少.
有时虽然所表示的时间概念相同,但有细微区别:
Having been show the lab,we left.被领着看了实验室后,我们就离开了.
Shown the lab,we left.被领着一看完实验室,我们就离开了.(有一种急促感)
