在名词后的动名词要改成定语从句只要把从句的时态与适当的引导词弄清即可.试举下例子：1 .I know the book costing him ten dollar is interesting(i know the book which costs him ten dollar is interesting)2.maybe you can not imagine how hard it is for us to finish this task wasting our emergy(maybe you can not imagine how hard it is for us to finish this task which is wasting our emergy)..一般引导词都是做从句主语的,那么谓语成分的多种形式等同于动名词原形的多种形式.
