I found him doing his homework. 2. The teacher found the composition written in very poor English. 3. I saw him come downstairs. 4. Have him do it. 注意:当有“感官动词或使役动词(get 除外)+ 宾语+宾补(不定式)”的句子变为被动语态时，原来不带 to 的不定式需带 to。,（动作已结束）,（将来发生的动作）,（动作已完成或结束，并有被动含义）,（动作同时发生或正在进行）,高考点击: The young man was often seen _ by the lake.(2007) A. to draw B. to drawing C. draw D. drew 2.
