3. 带逻辑主语的动名词
　　动名词可以有逻辑主语，其构成形式为“名词或代词的所有格+动名词”。带逻辑主语的动名词又称为动名词的复合结构，在句中用作主语,宾语,表语和介词的宾语。在非正式语体中，如果动名词的复合结构在句中作宾语，也可以宾格来充当动名词的逻辑主语。但考生需注意的是，在各种英语测试中，专家们仍坚持在正式语体中用代词的所有格来作动名词的逻辑主语。

　　Your driving a car to New York took longer than I expected.
　　I appreciated her devoting herself to the cause of education.
　　Your mother will be astonished at your coming home so late.
　　What we felt uneasy about was Li Ming’s having too much confidence in himself.
