这题考查的主要是过去分词作状语的用法,
A.puzzled 表示的是动作的完成,已经相当于一个形容词.
而B.being puzzled表示的动作正在进行,是现在分词的被动式.
根据句意,这个小男孩先对这个问题不解,所以才不知道如何回答,动作先生,所以A 是对的.

A
原句应该是the boy,(who was) puzzled at what the question was put.....
who was 被省略了
希望帮到你了!
望采纳!(*^__^*)

这里可以看做是一个定语从句。。。完整的应该是The boy, _who was puzzled__ at what the question was put, didn't know how to answer it.此处省略who was

这里是过去分词做状语
为便于理解 可以还原为 who was puzzled at the......省略 who +be动词(was)
being puzzled表示正在惊讶,而没有被动意味,如果要这样用 句子就有语法错误了 而且也不符合句意
