这种非谓语动词一般用作后置定语,修饰前面的名词,与前面名词之间是被动关系.除了你说的to be done,being done 还有done,总共三种形式,区别在于时间上done 表已发生的动作being done表正在被做的动做to be done表将要被做的动作例:The book written by him (last year) is interesting.他(去年)写的那本书很有趣.The book being written by him (this year) is interesting.他(今年)正在写的那本书很有趣.The book to be written by him (next year) is interesting.他将于(明年)写的那本书很有趣.
