动名词做主语和宾语 .

主语是执行句子的行为或动作的主体，如Байду номын сангаас“我写字”中的“我”，就是主语，它做出 “写”这个动作。
宾语是动作、行为的对象，是动作的 承受者。“字”是接受谓语“写”这 个动作的对象，它因此被称为宾语。
Examples:
———————
Smoking is harmful to your health. 吸烟有害健康。 (smoking在句中作主语。)
2. 动词接V-ing或to do 做宾语的区别 （意义差别很大）
1.时间不同 Frogs(蛙)是“两栖”，不是“过去”，就是 “将来” F ------------------ r -------- -------- og ----------- s forget remember / regret go on stop
It is/ was hardly/ scarely worth doing... 做...是不值得的。 It is hardly worth helping him. Helping him is hardly worth.
It is/ was useless doing... 做...是没有用处的。
2.意义不同 try + doing + to do mean + doing + to do
can't help to do 不能帮着做... can't help doing 禁不住做...
“试着做某事” “尽力做某事” “意味着” “想做某事”
b. 还有一类动词（短语）可接V-ing形 式或不定式做宾语，但意义区别较大。
3. V-ing做真正宾语，it做形式宾语的句型
用it做形式宾语，真正的宾语是V-ing短语，其 结构如下： think consider + it find feel like useless no use no good ...
It is no use waiting here．在这儿等是 没用的。(It为形式主语，waiting here 为真正的主语) waiting here is no use.
It is no good smoking. 吸烟是没有好处的。 (It为形式主语，smoking为真正的主语) smoking is no good.
②其他:can’t help （情不自禁)/insist on/put off(推迟)/can’t bear/ stand（不能 忍受） feel like/ succeed in/depend on /be fond of/be worth/ in addition to/have difficulty in doing
避免 错过 (少) 延期 avoid miss delay / postpone 建议 完成 (多) 练习 suggest / advise finish practise
喜欢 想象 禁不住 enjoy / appreciate imagine resist / can’t help
承认 否定 (与) 嫉妒 admit deny 逃脱 冒险 (莫) 原谅 escape risk pardon / excuse 忍受 保持 (不) 在意 stand keep/keep on mind
d. 注意: 在allow, advise, forbid, permit后 直接跟动名词作宾语，如果有名词或代 词作宾语，则构成“allow／advise／ forbid／permit ＋名词／代词＋不定式 (宾语补足语)”之形式。如： We don't allow smoking． We don't allow anybody to smoke． I wil permit doing so. to do so I will permit him ________.
