4. -ing分词的语法作用

-ing分词一方面具有动词的性质，另一方面也相当于一个名词或形容词、副词，在句中可以作主语、表语、宾语、定语、状语和补语等。

1)–ing分词(短语)作主语：

Laying eggs is the ant queen's full-time job. 产卵是蚁后的专职工作。

Saying is easier than doing. 说比做容易。

在下面两种结构中，-ing分词也作主语。

①为了保持句子平衡，通常用作形式主语，而把真实主语放在句末。如：

①–ing分词作动词宾语。如：I suggest doing it in a different way. 我建议用另一种方法做这件事。

③-ing分词作介词宾语，经常用在一些短语的后面。如：

注：-ing分词作状语时，它的逻辑主语就是整个句子的主语。
