（二）动名词（doing）
1、动名词的语法功能
（1）作主语
Swimming is never as fast as running.
注意：动名词（或动名词短语）作主语时，有时句中使用形式主语it，如：
It is no use talking about it.
谈论此事并无用处。
注意：
不定式和动名词都可以做主语，在意义上区别不大。
例如：
It is impossible to get there before dark.
It is impossible getting there before dark.
但在下列固定结构中，只能用动名词做主语，不能用不定式：
It is no good doing…
It is no use doing…
It is worthwhile doing…
It is a waste of time doing…
例如：
It is no good objecting反对没有用。
It is no use crying哭没有用。
It“s worthwhile reading the book.读这本书很值。
（2）作宾语（动词或介词的宾语）
Would you mind waiting for a moment？
有少数动词用动名词作宾语，如下所示：
acknowledge承认　admit 承认　appreciate 感激
avoid避免　delay延迟　deny否认
escape逃避　keep保持　mind 介意
permit 允许 postpone延迟 resist抵抗
risk冒险 prevent阻止　quit放弃停止
recommend 推荐 suggest建议
