【要义详析】　　动词-ing由“动词原形+-ing” 构成。动词-ing形式可在句中作主语、宾语、表语、定语、宾语补足语和状语, 但不能单独作谓语。
1. 动词-ing形式作定语如果是单个的动词-ing形式作定语, 常放在被修饰词前作前置定语; 如果是动词-ing形式短语作定语, 则放在被修饰词后作后置定语。*Make less nise. There’s a sleeping child. 不要发出太大声音, 有个正在睡觉的孩子。
*He asked me an embarrassing questin. 他问了我一个令人尴尬的问题。*The yung man sitting between Jhn and Mary is the editr f the campus newspaper. 坐在约翰和玛丽之间的那个年轻小伙子是校园报的编辑。
*The man being questined is cnnected with the traffic accident. 正在被提问的那个人和这起交通事故有关。*The patient has stayed in the waiting rm fr half an hur. 那个病人在等候室里已经待了半小时。
*There is a swimming pl behind the beautiful garden. 在这个美丽的花园后面有一个游泳池。
【易错精点】1. 表示感情的动词-ing形式作定语时, 表示“令人……的”, 此类动词-ed形式作定语时, 表示“感到……的”。2. 动词-ing形式作定语如果与被修饰的词之间是被动关系, 且强调动作正在进行就用动词-ing形式的被动式, 即being dne的形式。
【知识延伸】动词-ing形式作定语的两种作用1. 用来说明被修饰的名词a waiting rm = a rm fr waiting等候室a walking stick = a stick fr walking拐杖a sleeping car=a car fr sleeping卧铺
2. 指所修饰的名词正在进行的动作, 与被修饰词之间是主动关系, 可以换成定语从句的形式a man waiting at the stp= a man wh is waiting at the stp在停车点等候的人 a sleeping child = a child wh is sleeping正在睡觉的孩子
【即学活用】句型转换(1)The taxi that tk us t the airprt brke dwn. →The taxi ______us t the airprt brke dwn. (2)The prblem that is being discussed is abut fd safety. →The prblem ______________is abut fd safety.  
being discussed
(3)The student stayed in the rm used fr reading fr an hur. →The student stayed _________________fr an hur.  (4) That was an experience that frightened everyne. →That was _____________________.  
in the reading rm
a frightening experience
2. 动词-ing形式作表语一种表示主语的特质、特征和状态, 其作用相当于形容词; 另一种具体说明主语的内容, 即主语等同于表语, 两者可互换。*The music they are playing sunds s exciting. 他们演奏的音乐听起来令人激动。
*The result is disappinting. 结果令人失望。*Our jb is playing all kinds f music. 我们的工作就是演奏各种音乐。*Seeing is believing. 眼见为实。
