二、动名词用作宾语 动名词作宾语有两种情况。 1. 只能后接-ing作宾语的动词, 常见的有 avoid, consider, enjoy, keep, finish, suggest, dislike, delay, escape, cannot help, imagine, mind, miss, practise, cannot stand, excuse, fancy, give up, put off, risk, insist on, look forward, feel like等。 e.g.
3. 在there be no...结构中作主语, 这种结构 的意思相当于“It is impossible to do… ”。
• There is no sense in doing 做……没有道理 • There is/was no use doing 做……无意义 • There is/was nothing worse than doing
The –ing form 构成: 1.一般情况 rain------raining 2.以e结尾的动词 hope-----hoping 3.重读闭音节的动词
stop-----stopping 4.以ie结尾的动词
die-----dying lie---lying tie----tying
归纳总结:
• In the dream Peter saw himself raunn after by a fierce wolf, and he woke suddenly.
• The wild flowers looked like a soft orange blanket covering the desert.
2. 既可接-ing和to do作宾语的动词, 常见的有:

2. -ing形式作主语时常后置, 此时须用it 作形式主语, 用形容词或名词作表语。 常见的名词或名词短语有: no use,
no good, fun, hard work, a hard / difficult job, a waste of time 等; 形容词有: dangerous, worthwhile, useless等。

Don’t forget to write to your mother. I regret missing the report. I regret to say I can’t take your advice.
