英语时态提问：大哥大姐们帮我看看下面这句话的时态,搞不清楚了.
The inspector pointed out that on the morning of the murder,the 8 o'clock train did not run at all,as it had broken down at Ferngreen station and had been taken off the line.为什么：the 8 o'clock train did not run at all 不用过去完成时?为什么：as it had broken down at Ferngreen station and had been taken off the line.在主句使用一般过去时的情况下,从句使用过去完成时,主句和从句是同时发生的呀?

这里只是阐述一个过去的事实＂8点钟火车就停止运行了＂不使用完成时大家也默认已经发生了.
as引导的从句表示原因 正是这个原因导致主句的火车应该停运 不知道上下文如何 单平这两句话我认为从句发生在主句之前 因此过去完成时是过去的过去
