辨析: 一.动名词与现在分词当定语时的辨析: ★动名词:说明它所修饰的名词的作用和用途。
★现在分词:表示它所修饰的名词正在进行的动作，与所修饰的词有逻辑上的主谓关系,相当于一个定语从句. 例如: There is a swimming pool in our school. (动名词,表用途,作用) = There is a pool for swimming in our school. ★I found a sleeping baby on the bed. (现在分词,表正在进行的动作) = I found a baby who is sleeping on the bed. ★The boy standing there is my classmate.(现在分词，表正在进行的动作。)= The boy who is standing there is my classmate
