doing是非限制性的一种形式,动名词在句子中起名词的作用,如:Reading is important in learning English. 学英语,阅读是很重要的。 Looking after the patient is a nurse's job. 照顾病人是护士的工作。 动名词是由动词原形 + ing 构成,同现在分词形式一样,在句中可作主语, 宾语,表语和定语。 1) 动名词作主语: Talking like that is not polite. 那样谈话不礼貌。 Learning from others is important . 向别人学习很重要。 动名词可以象动词不定式一样,用 it 先行祠代替, 而把动名词写在后面。 It's no use waiting here, let's go home. 在这儿等着也没用,我们回家吧。 2) 动名词作表语 The nurse's job is looking after the patients. 护士的工作是护理病人。 Seeing is believing. 眼见为实。 3) 动名词作宾语 有些动词须用动名词来作宾语,它们是begin, mind, suggest, finish, stop, need, enjoy, miss, keep. Please stop smoking in the house. 请不要在家里抽烟。 I like reading in the forest. 我喜欢在树林里读书。 Do you mind my opening the windows? 你介意我打开窗户吗? 4)动名词作定语 She is studying in the reading room. 她在阅览室学习。 He slept in the sleeping bag. 他在睡袋里睡觉。
