III、非谓语动词 非谓语动词在句中不可单独作谓语，不受主语的人称和数的影响，但是可用作其他句子成分。非谓语动词有三种，即不定式，动名词和分词。 不定式和动名词的区别： 不定式和动名词都可作主语,表语和宾 语，有时二者可互换。但按照传统语法，二者的区别表现为： 动名词表示：笼统、泛指的意思 / 抽象或 经常性的动作 / 已成为过去或经验之谈 不定式表示：一时性的具体的或特定的动 作 / 现在或将来的动作 资料：例子 补充 :A postman’ duty is delivering mails. Your task this morning is to deliver the papers to Professor Smith. 二、非谓语动词的句型 (1) It takes sb. + some time + to do = sb. spend some time (in) doing It took me three hours to finish my assignment. I spend three hours ( in) finishing my assignment. (2) It is + adj. + for sb. + to do 不定式可以有自己的逻辑主语，通常有两种形式： for sb. + to do / of sb. + to do It is very difficult for us to finish the task . (3) It is + adj. + of sb. + to do (常用的形容词有：kind, nice, considerate, thoughtful, stupid, wise, brave，good, careful, polite, rude, clever等.)表示人物性格，特征等形容词之后，常用of 引出不定式的在逻辑主语 It was very nice of you to think so much of us. 练习题52 （4），（5）看资料 (6) have difficulty (trouble, fun, a hard time, a good time) + (in) + doing sth.
