Grammar-动词的ing形式作定语、表语和宾语补足语

1、Grammar 动词的-ing形式作定语、表语和宾语补足语1、 作定语：动词的-ing形式作定语时起下列作用：1. 说明被修饰名词的功能或用途，这时，一般是单个 v.-ing 而不是短语，放在被修饰的名词前面。可以转换成“for + v.-ing”短语修饰该名词。这时的v.-ing是动名词。e.g. a sleeping bag = a bag for sleeping 睡袋 a reading room = a room for reading 阅览室 a drinking cup = a cup for drinking 饮用杯 a writing desk = a desk for wr

2、iting 写字台 a washing machine 洗衣机 a swimming pool 游泳池 a dancing hall 舞厅2. 说明名词的动作、特征、或性质。这时的v.-ing 是现在分词，它与被修饰的名词是逻辑上的主动关系。单个的现在分词作定语时放在被修饰名词的前面，常可转换成定语从句。e.g. a sleeping boy = a boy who is sleeping a drinking horse = a horse which is drinking a moving story = a story which moves people a terrifying s

3、ound = a sound which terrifies people an inspiring leader = a leader who inspires people现在分词短语作定语时要后置，即放在被修饰名词的后面。常可转换成定语从句。e.g. The girl swimming in the river (who is swimming in the river) is good at dancing. Do you know the man standing / (who is standing ) at the door? The boy studying / (who is

4、 studying) in the classroom is our monitor. 作定语用的v.-ing 是动名词还是现在分词并不重要。重要的是要掌握v.-ing 做定语的用法。实际上，当代一些著名语法专家已把动名词和现在分词统称为v.-ing 分词而不予细分了。2、 作表语：动词的-ing 形式作表语时起下列作用：1. 说明主语的内容，可换到句首做主语。这时的v-ing 形式是动名词。e.g. The real problem is getting to know the needs of people. Her job is teaching children to dance. =

5、 Teaching children to dance is her job.2. 说明主语的特征。这时的v.-ing 形式是现在分词。它与主语是逻辑上的主动关系，意思是“使人 . 的”e.g. The situation is encouraging. What he said just now is confusing. (confuse). The news is shocking. (shock).能这样用的现在分词最常见的还有：astonishing, amusing, confusing, disappointing, boring, encouraging, inspiring,

6、 moving, tiring, interesting, surprising, charming, exciting, missing, puzzling, frightening.3、 作宾语补足语：动词的-v.-ing形式能跟在宾语后面，对其作补充说明，因此称为宾语补足语，通常简称为“宾补”。1. 这时的v.-ing 形式是现在分词，它与宾语是逻辑上的主动关系。e.g. When I arrived at the reading room, I found many students reading carefully there. Children like to watch the

7、 PLA men training (train) on the drill-ground.

8、eone knocking gently on the window.在see, hear, feel, watch等感官动词后，既可用动词的-ing形式作宾补，也可以用省略to 的不定式作宾补。用动词的-ing 形式时，表示动作正在进行；用省略to 的不定式时，表示动作从开始到结束的全过程。 e.g. I saw a boy getting on the bus. (表示动作正在进行) I saw a boy get on the bus. （表示动作的完成了） Do you hear someone knocking (knock) at the door? ( 表示动作正在进行 ) I

9、heard someone knock at the door three times. ( 表示完整的动作 ) 表示使意义的使役动词：(have, let, keep, get, leave.) + sb./sth. + doing sth. e.g. We kept the fire burning all night long.
