A. to draw B. to drawing C. drawing D. drew为什莫不选A啊而选C

试题就是考see sb do 的结构

1）感官动词see,watch,smell，notice等在主动语态时后接动词do或者doing

see sb do sth-------------被动式为sb be seen to do。
see sb doing--------------被动式为sb be seen doing。

 see sb do sth表示“看见某人做了某事”，强调看到某人做完了某事（强调结果）

 see sb doing sth表示“看见某人正在做某事”，强调某人正在做某事(强调过程)

比较下列两句：

I saw him repair his bike. 我看见他修了他的自行车。（他已修完了自行车）

I saw him repairing his bike. 我看见他正在修他的自行车。（强调看见正在修车）

2）所以题目The young man was often seen ____ by the lake.
换成主动态： He often saw the young man____by the lake.

显然主动态应该填 draw，句子强调的是看见动作的结果，而不是过程。
被动态就为： be seen to do ,自然选A

be seen to do这个的意思就是说过去被看见做什么事情。已经是过去式。 be seen doing这个是过去被看见正在做什么事情，这个语法是过去正在进行时

see不定代词作宾语补足语，后不加to所以不选A
