Christmas carols 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 materials＝materials for building建筑材料a reading room＝a 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 problem＝a problem that puzzles somebody一个困扰人的问题a surprising result＝a result that is surprising一个惊人的结果developing countries＝countries that are developing发展中国家2．v.­ing形式短语作定语时，放在所修饰的名词之后，并且在意思上相当于一个定语从句。They lived in a room facing the street.＝They lived in a room that faces the street.他们住在一间面朝街的房子。The man standing there is Peter's father.＝The man who is standing there is Peter's father.站在那儿的那个人是彼得的父亲。3．v.­ing形式短语也可以用作非限制定语，相当于一个非限制性定语从句，这时，它与句子其他部分用逗号分开。The apple tree, swaying gently in the breeze, had a good crop of fruit.＝The apple tree, which was swaying gently in the breeze, had a good crop of fruit.那棵苹果树硕果累累，在微风中轻轻摇曳。His brother, working as a teacher, lives in Beijing.＝His brother, who is working as a teacher，lives in Beijing.他的哥哥住在北京，是个老师。[名师点津]　有些情况下，动词的­ing形式不能用来作定语，必须使用定语从句。作定语的v.­ing形式表示的动作要与主句谓语的动作同时发生，如两者不能同时发生的话，则需使用定语从句。[误]The professor coming here yesterday will give us a lecture.[正]The professor who came 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。[即学即练1]　句型转换①The taxi that took us to the airport broke down.→The taxi taking us to the airport broke down.②The problem that is being discussed is about food safety.→The problem being discussed is about food safety.③The student stayed in the room used for reading for an hour.→The student stayed in the reading room for an hour.④That was an experience that frightened everyone.→That was a frightening experience．二、v.­ing形式作表语v．­ing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2]　单句语法填空①It is amazing(amaze) that the boy is able to solve the problem so quickly.②Buying a car is simply wasting(waste) money.③Please stop making the noise—it's getting
