I saw him ( )under a tree ,thinking.求语法讲解.

问题描述:

I saw him ( )under a tree ,thinking.求语法讲解.
A.sat
B.seated
C.seating
D.seat
但我选C,我是这样理解的:I 主语 saw谓语 him 宾语satting under a tree宾补 .然后him和satting是主谓关系(就是主动关系),所以C没错呀!

seat是及物动词,你用seating的话,后面没有宾语,但是可以有被动,seated是落座,就坐
如果是sit,不及物动词,才可以用sitting那seating怎么解释?就是及物动词的角度考虑,用seating,没有跟宾语,不行啊,under the tree是状语,不是宾语 sit不及物,可以不跟宾语
