非谓语动词就是不能充当句中谓语的动词。非谓语动词包括动词不定式、动名词、现在分词和过去分词，在句中可以作主语、宾语、表语、定语、状语和补语等。 一、非谓语动词的时态和语态 非谓语形式 主动形式 被动形式 动词不 定式 一般式 to do to be done 进行式 to be doing \ 完成式 to have done to have been done 完成进行式 to have been doing \ 动名词 一般式 doing being done 完成式 having done having been done 现在分词 一般式 doing being done 完成式 having done having been done 过去分词 done \ \ (1)非谓语动词的一般式：其所表示的动作与谓语动词所表示的动作几乎同时发生或发生在谓语动词所表示的动作之后； (2)非谓语动词的完成式：所表示的动作发生在谓语动词所表示的动作之前； (3)非谓语动词的否定形式：在非谓语动词的前面加not，如not to do, not doing, not to be done, not having done。 二、非谓语动词作主语 非谓语动词作主语只能是不定式和动名词这两种形式，分词不能作主语。非谓语动词作主语时，谓语动词通常用单数形式；有时为了保持句子结构平衡，常用it作形式主语，而将非谓语动词后置。 1．动词不定式(短语)作主语 (1)动词不定式(短语)作主语时，多表示具体的、一次性的或尚未做的动作。 ◆To do exercise is beneficial to our health. 锻炼有益健康。 ◆To form a good habit of learning is important for us students. 养成良好的学习习惯对我们学生来说很重要。 (2)it作形式主语的常用句式： ①It is＋adj.＋(of/for sb) to do sth 做某事(对某人来说)是……的 ②It be＋a/an＋名词＋to do sth 做某事是…… ③It takes (sb) some time/courage/patience/...to do sth 做某事花费/需要(某人)一些时间/勇气/耐心/…… ④It's up to sb to do sth 做某事由某人决定；做某事是某人的职责 ◆It is important for you to walk after supper. 晚饭后散步对你很重要。 ◆It is kind of you to take me to the

了解你自己的需要和交流方式与学会表达你的喜爱和情感一样重要。 (2)it作形式主语的常用句式： ①It's no use/good doing sth 做某事没有用 ②It's a waste of time/money doing sth 做某事浪费时间/金钱 ③It's fun doing sth 做某事很有趣 ④It's worth doing sth 做某事是值得的 ◆It is a waste of time arguing with him about the matter. 同他争论这件事真是浪费时间。 ◆It's no use waiting here.You should take action immediately. 在这儿等无济于事。你应该立刻采取行动。 不定式作主语时多数情况下可以用动名词(短语)替换，但在以下情况下不能替换：(1)一些固定说法中；(2)表示较强烈的对比时。 To err is human. 人非圣贤，孰能无过。 To respect others is to be respected. 尊重别人就是尊重自己。 To forgive is to be forgiven. 原谅他人就是原谅自己。 [即时演练1]——单句语法填空
