(单选题)

______ which way to take, the little boy behaved like a real gentleman who comforted his sister from time to time.

A.Leaving to wonder

B.Left wondering

C.Having left to wonder

D.Left to wonder

参考答案：B

参考解析：

考查过去分词作状语和现在分词作主语补足语。句意：这个小男孩不知道该走哪条路，他表现得像个真正的绅士，不时地安慰他的妹妹。leave用过去分词作伴随状语，与主语是被动关系，故用过去分词left，wondering是主语补足语，说明主语当时的状态。原句= the boy was left wondering which way to take, and he behaved like a real gentleman. 选项A、C是现在分词作状语，与主语是主动关系，故排除。选项D用不定式作主语补足语，表示的将要发生的事，与本句意思不符合。故选B。
