Step2: persentation （一）v-ing的基本用法

V-ing具有名词性质，可在句中做主语、宾语、表语、定语、宾语补足语和状语，但不能单独做谓语。

（二）v-ing作主语的用法 1. v-ing置于句首做主语，往往表示经常性、习惯性的动作。

Eg. Painting is his hobby. 2.

it做形式主语，v-ing充当真正的主语放在后面。

It is useful / useless It is worthwhile It is no use

doing sth. It is no good It is no pleasure It is a waste of time Eg. It is useless trying to argue with Shylock. It is a waste of time arguing about it. 3.

There is no use / point doing sth. （三）v-ing做宾语的用法

1.

当v-ing短语做宾语，后面有宾语补足语时，常用it做形式宾语，v-ing短语放在后面。
