16、动词动作发生时，不定式的动作正 在进行。 Eg. Some students pretended to be reading English when the teacher came in. 不定式完成式由 to have + V-ed 构成，用来表示动作发生在谓语动作之前。 Eg. 2005 年江苏卷 No.25 - Is Bob still performing? - Im afraid not.

26、utting up C. making up D. showing up 答案为 C 作定语 动名词可作前置定语，表示所修饰的词的用途或目的，可用 for 改写；而现在分词作定语 时，可用定语从句改写。 swimming pool waiting room walking stick a sleeping car=a car for sleeping a sleeping child= a child who is sleeping 作同位语 eg. Thats the queens full-time job, laying eggs. 这就是蚁后的专职工作产卵。 2动名词的逻辑主语 人称代
27、词做逻辑主语时应用所有格，即形容词性物主代词。 Eg. Do you minding my smoking here? 逻辑主语是不定代词或指示代词时，很少用所有格，而用普通格。 Eg. He was awakened by someone knocking the door. Theres no need for that being done. 逻辑主语是名词时，用所有格，但是如果名词为无生命物体时，则用普通格。 Eg. Marys laughing made Tom angry. There is no hoping of the factory making profit. 在口语中，
