合结构就是在动名词前加上其逻辑主 语，其形式是：名词所有格('s) +doing 或形容词 性物主代词(one's )+doing . 这种结构可以在句中 做主语或宾语。
1. The president's attending the meeting himself gave them a great deal of encouragement. （主语） 2. I would appreciate your calling back this morning. （宾语）
1. I appreciate____me during the debate. A. of your supporting B. you to support C. your supporting D. to your supporting 2. We were surprised at ____ the exam. A. him not pass B. his passing not C. his not passing D. him not to pass
。
但是，在口语中，当动词-ing的复合结构在句中 做宾语，特别是当它做介词的宾语时，其复合 结构中的名词所有格可用名词的普通格代替， 形容词性的物主代词可以用代词的宾格形式代 替。
1. He thought of passenger('s )waiting for help.
2. He insisted on me going to help her.
