5）

在复合宾语中，用it作形式宾语，将动名词短语放在后面。例如：

+ doing”结构中作主语，it为形式主语。例如：

4）

动名词在“There is(was) no + doing”结构中作主语。例如：

3. 动名词的被动式

动词need, require, want, deserve后，用动名词的主动形式表示被动意义。其用法相当于不定式的被动结构。例如：

The watch needs repairing. (=The watch needs to be repaired.)

The problem deserves thinking about. (=The problem deservers to be thought about.)

2）

在（be）worth后面只能用动名词的主动态来表示被动意义。例如：

His suggestion is worth considering.

4.总结动名词的用法，写6个句子或一篇小短文，真正把动名词的用法理解和运用。
