课堂探究
一、动词的-ing概述
动词的-ing形式作定语在句中通常有两个位置,如果是单个的动词的-ing形式作定语,常放在被修饰词前作前置定语;如果是动词的-ing形式的短语作定语,常放在被修饰词后作后置定语。如:
1) He is an attacking player. 他是一个攻击型的运动员。
2) He asked an embarrassing question. 他提了一个令人难堪的问题。
3) A little child learning to walk often falls. 学走路的小孩常常跌跤。
4) Do you know the number of people coming to the party?你知道来参加晚会的人数吗?
二、动词的-ing的作用
1. 动名词说明被修饰词的性质、特征或用途。
1) They set up an operating table in a small temple. 他们将手术台架设在一座小庙里。
2) He may be in the reading room, for all I know. 据我所知,他说不定在阅览室里。
3) Ladies and gentlemen, please go and wait in the meeting room. 女士们先生们,请去会议室等待。
2. 现在分词与被修饰词为主动关系且表示正在进行的动作。
1) There were about 200 children studying in the art school. 有大约二百个孩子在这所艺术学校学习。
2) Who is the woman talking to our English teacher? 正在和我们英语老师谈话的那位女士是谁?
3. 有些v.-ing形式已经转化成形容词,常作定语用来修饰物,表示“令人……的”。常用的此类词有:exciting,amusing,amazing,astonishing,shocking,puzzling,confusing,disappointing,discouraging,pleasing,striking,boring, tiring,touching,moving,interesting,satisfying,terrifying,frightening等。
1) That must have been a terrifying experience. 那准是一段可怕的经历。
2) The experiment was an amazing success. 那项试验是一个惊人的成功。
注意:作定语的及物动词的现在分词形式为doing和being done。当被修饰的名词与分词之间为主动关系时,用doing;当被修饰的名词与分词之间为被动关系且表示动作正在进行时,用being done。作定语的不及物动词的现在分词形式只有doing。
1) He spoke in a low voice in order not to wake the sleeping child. 为了不吵醒那个正在睡觉的孩子,他说话声音很低。
2) Can you see the star moving in the sky? 你能看见那颗在天上移动的星星吗?
3) The film being shown in the cinema is exciting. 正在电影院上映的那部电影很令人激动。
