动名词（动词-ing）作主语
基本情况动词­ing形式是动词的一种非谓语形式，包括现在分词和动名词两种。 动词­ing形式在句中的语法作用：动名词在句中作主语、宾语、表语和定语，现在分词在句中作状语、宾语补足语和定语。

【观察例句】1. Saying is ne thing, and ding is anther.说是一回事，而做是另一回事。2. Having a walk every day helps t make ne keep healthy.每天散步有助于一个人保持健康。
【归纳用法】动词­ing形式作主语，往往表示经常性、习惯性的动作，通常置于句首。
形式主语it代替动词­ing形式作主语

【归纳用法】 动词­ing形式和t d都可以作主语。动词­ing形式作主语表示比较抽象的一般行为，t d作主语往往表示具体的或一次性的动作。
