23、。The room needs/requires/wants cleaning.The room needs/requires/wants to be cleaned.=1、动名词带上自己的逻辑主语，这便构成了动名词的复合结构。2、其逻辑主语一般由物主代词、名词所有格、人称代词的宾格和名词来充当。在口语中，物主代词和名词所有格可分别由人称代词的宾格和名词的通格代替。e.g.:Do you mind my/me opening the door?I cant imagine Marys/Mary marrying such a young man.动词-ing形式的复合结构3、在下列情况下二者不

25、ing with fire?The father insisted on John and Marywalking to school.3)当逻辑主语是this,that,somebody,someone,nobody,none,anybody anyone时用其通格形式。He disapproved of that being said about John.The teacher dislikes anyone being late.He insisted on this being true.动名词的构成：时态语态一般时完成时主动式（not)doing(not)having+done被动
