1.she was ——for work by accide.
be late for 是固定用法 记住就可以了

后半句“she was reading” was 就告诉了我们,时态是过去时
所以用了lied,而不用lies
3.listen!who is ——on the door.
这个开头的"listen!" 有正在进行的意味,就是说明事情正在进行,所以用的进行时knocking

have 加过去分词 是现在完成时,表描述从过去某时到现在为止这一段时间中发生的情况 【 也就是说“我们一直认识了这么多年” 】所以是known,不是know

struggled to stand on his feet
A分开的过去时/单独的

例子

study的动作发生在said之前
