what did you do three hour ago 是过去进行时吗？ what were you going at 8 o'clock yesterday 这句呢

what did you do three hour ago 是过去进行时吗？ what were you going at 8 o'clock yesterday 这句呢

第一句不是，第一句是过去式。
第二句是过去进行时。追问为什么第一句不是呢？
what did you do three hour ago
也是问过去的某个时刻，你在做什么啊？为什么第一句不是呢？
what did you do three hour ago
也是问过去的某个时刻，你在做什么啊？追答不是问的某个时刻，问的是三小时以前，不是一个精确的时间点，你不需要这么死抠。你就看句子里面用的词你就知道了，did就是过去式，was doing就是过去进行时。追问谢谢，我还有个问题请教一下
I went to your house at 8:30 yesterday morning to find you
（to find you为什么要放在句后面呢，不是时间放后面吗 ）
I went to your house to find you at 8:30 yesterday morning追答都可以。这个没有硬性的规定。
