问题描述：

I saw him ___the key ___the lock,turn it and open the door A.pointing；in B.put; in C.putting ;to
D.point ;to

答

put,in
put是一个省掉to的动词不定式，是及物动词see的复合宾语。see后面的不定式必须要省掉to,这是语法规则。
从整个句子看，就是一个普通的一般过去时。用动词不定式是地道用法。选putting则是误人子弟,怎么能被选为满意答案呢？

答

C see sb doing sth 看见某人正在做某事（see sb do sth 看见某人做某事的全过程）
the key to the lock 固定用法类似的还有 the answer to the question

I saw him ___the key ___the lock,turn it and open the door A.pointing；in B.put; in C.putting ;toD.point ;to
