A climbing B climb C having climbed D have climbed
请仔细讲解下每个选项,
顺便再问下accustomed to后的非谓语动词有什么特殊规定吗?例如说只能用doing形式

Answer 1

be accustomed to doing 是固定搭配 排除BD
C表示climb的动作在前,习惯在后 不符合题意
because he was accustomed to climbing the steep mountains,he had no difficulty reaching the top,
be accustomed to doing 是固定搭配 唯一的一种用法
