3、ls and wishing each other“Merry Christmas！”归纳用法一、v.ing形式作定语1单个动词的ing形式作定语位于被修饰名词的前面，既可以表示被修饰者的作用或功能，也可以表示被修饰者的动作或状态。(1)说明被修饰名词的用途和性能。building materialsmaterials for building建筑材料a reading rooma room for reading阅览室(2)表示所修饰的人或物的动作或状态，在意思上接近一个定语从句，可以表示正在进行的动作，也可表示经常性动作或当时的状态。a puzzling problema problem

7、e here yesterday will give us a lecture.昨天来的教授将要给我们做一个讲座。动词ing形式的完成式一般只用作状语，不作定语。误The temple having been destroyed by the earthquake will be rebuilt soon.正The temple(which has been)destroyed by the earthquake will be rebuilt soon.被地震毁坏的庙宇很快就要重建了。二、v.ing形式作表语ving形式作表语可分为两种情况：现在分词和动名词。现在分词作表语主要表示主语的性质
8、和特征，而动名词作表语则主要是对主语内容的进一步说明和解释。My job is interesting.我的工作很有趣。My job is teaching.我的工作是教书。提示现在分词和动名词作表语时的区别：第一句中的interesting为现在分词，它表示“工作”的特征；第二句中的teaching为动名词，它是对“工作”内容的进一步说明。正因为如此，动名词作表语时可与主语交换位置，而现在分词作表语则不可与主语交换位置。误：Interesting is my job.正：Teaching is my job.即学即练完成句子1你告诉正在那边玩耍的孩子们别制造噪音了吗？Did you tell
