Section 3　Grammar—动词­ing形式作主语 语法图解 观察句子 1．It was foolish of you to lie to your teacher. 2．It's no use trying to persuade him to change his mind. 3．This is an English－speaking country. 4．In order to arrive there on time, I got up early. 我的领悟 1．句1、2中黑体部分在句中均作主语。 2．根据句1、2可知，动词不定式和动词­ing形式作主语时，可以用it作形式主语。 3．句3中的动词­ing作定语，句4中的不定式作状语。 一、非谓语动词 1．概念 非谓语动词是指在句子中不作谓语的动词。 2．结构形式 时态形式 主动式 被动式 不定式 一般式 to do to be done 完成式 to have done to have been done 进行式 to be doing — 动词­ing形式 一般式 doing being done 完成式 having done having been done 动词­ed形式 一般式 — done 二、句法功能：在句中充当除谓语之外的其他成分(主语、宾语、表语、定语、状语等)。 过去分词done不能充当主语和宾语；having (been) done不能作主语或定语。 1．动名词/to do作主语 动名词作主语表抽象的习惯性的动作；不定式作主语表示具体的、某一次的行为。 ①Climbing mountains is a good way to keep fit. 爬山是保持健康的好方法。 ②To complete the work needs time. 完成这个工作需要时间。 2．动名词/to do作主语，常用it作形式主语，用于以下结构中： (1)It's no use/good/fun/pleasure doing sth It's no use complaining that you don't have an opportunity to land an ideal job. 抱怨没有机会得到一份理想的工作是没有用的。 (2)It's＋adj.＋(for/of sb)＋to do sth 能搭配of或者for的形容词有哪些？归纳如下，请牢记！ It's kind/brave/polite/careless/honest/clever of you to do...＝You are kind/brave/polite/careless/honest/clever to do... It's important/difficult/necessary/easy for you to do...(不能说You are important/difficult/necessary/easy to do...) ①It's brave of you to rescue the child from the burning house. 你真勇敢，从着火的房子里救出了那个孩子。 ②It's difficult for me to handle the problem. 我很难处理这个问题。 【小练】　单句语法填空 ①It is no use bothering (bother) about those who always stand still and refuse to make progress. ②In many countries, shaking(shake) one's head means “no” and nodding means “yes”． ③It is easy for me to learn how to drive. ④It is impolite of him to say so. 3．动名词的复合结构 逻辑主语是有生命的名词：作主语时，须用名词所有格或形容词性物主代词；作宾语时，也可用普通格或人称代词宾格。 ①Tom's (His) coming is what we have expected. 汤姆的(他的)到来是我们预料之中的。 ②She didn't mind Jack/Jack's (him/his) coming here. 她不介意杰克(他)来这里。 用所给词的适当形式填空 1．Walking (walk) is a good form of exercise for both young and old. 2．To_master (ma
