译林牛津版选修六Unit1 Laughter is good for you语法练习含答案
II 要点分析(本单元主要涉及非谓语动词作主语、定语和宾语补足语的情况)
1. 动名词和不定式作主语时的区别
1） 动名词作主语表示一般的抽象的习惯性的行为
2）不定式作主语表示具体的、一次性的或特指的动作
Playing with fire is dangerous. (泛指玩火)玩火是危险的。
To play with fire will be dangerous. (指某一具体动作)玩火将很危险。
【注意】to do 和 doing 会在不同的特定句式中充当主语
It is + adj. + to do (不定式做主语)
但是在以下句型中，主语由doing（动名词）充当。
It is useless/ no use/ no good doing sth.
It is no good arguing with him. He never listens to others.
和他争论没好处，他从不听别人的。
2. 不定式和动名词作宾语的区别
1）通常跟不定式作宾语的词有：afford, agree, want, wish, hope, refuse, manage, ask, offer, promise, pretend, decide, learn, determine, expert, beg, choose, force, intend attempt, fail, claim, long(v.), plan, prepare, would like(love, prefer), mean, seek等
He asked to be sent to work in Tibet. 他请求被派往西藏工作。
He refused to accept the job. 他拒绝接受这个工作。
2） 通常跟动名词作宾语的词有：acknowledge, admit, appreciate, avoid, consider, delay, dislike, enjoy, escape, excuse, feel like, finish, forgive, imagine, include, keep, mention, mind, miss, practise, resist, risk, suggest, stand, involve等。
Would you mind my opening the window? 你介意我开窗吗 ？
3）有些动词的后面可用不定式或动名词作宾语，但是意义差别很大。这些词有：forget, remember, regret, mean, stop, try, can’t help, go on等。
