答案

1、when he stepped in 做时间状语,修饰hardly had I sat down,when翻译成“当……时“.”then 是“然后”的意思,用于两句话之间的连接或者一句话的两个意思之间连接.你不能说“我还没来得及坐下然后他就进来了”,只能说“当他进来时我还没来得及坐下”.
2、such a thing 是固定搭配,翻译成”这么一个东西“,不能缺少a,固定搭配没有为什么.
3、be feeling表的是现在进行时,而非被动语态,wouldn't 是虚拟语气.被动语态后面应该跟过去分词而非现在分词.
4、本句为虚拟语气,前半句用过去式,后半句用would+现在时.现在完成时和过去完成时均用于对现在有影响的过去的事件,比如：we had accepted their terms, and we go bankrupt.
