英文语法问题

Did you close the door after you left?
Do you close the door after you have left?
Did you colsed the door after you had left?

I found my wallet after you left
I found my wallet after you had left

I took the books before you arrived
I had taken the books before you arrived

从英文语法上说，以上哪句话是正确的，并说明原因及语法。
这几个题目搞晕我了，请帮忙，谢谢！

Answer 1

以下三句正确：
Did you colse the door after you had left? （关门用了过去时，离开在关门之前发生，所以是过去的过去，用过去完成时）
I found my wallet after you had left. (离开在找到钱包之前发生，找到钱包用了过去时，离开只能用过去完成时)
I had taken the books before you arrived.(你来之前我拿到了书，来用了过去时，在这之前发生的事就要用过去完成时)

你这些句子都是考察对过去完成时的掌握的，过去完成时表示“过去的过去”，即在过去的某一动作之前已经发生或者完成的动作。

Answer 2

Did you close the door after you left? 其实是同时发生，用when比较合适
I found my wallet after you had left 先离开，后发现
I had taken the books before you arrived 先拿书，后到达

Answer 3

Did you close the door after you left?
I found my wallet after you left
I took the books before you arrived
以上正确。
leave（离开）,take（表示拿到的时候）是瞬间动词，不能用完成时，动作一做就完成了，完成时表示一段时间

Answer 4

Did you close the door after you left?连续动作
I found my wallet after you had left.注意after
I had taken the books before you arrived.注意before

Answer 5

Did you close the door after you left? 这句对。。LEAVE是瞬间动词。不能做过去完成的一个状态动词。
I found my wallet after you left。这句对。LEAVE是瞬间动词。不能做过去完成的一个状态动词。可以换成GO。AWAY。等表状态的词。这句是强调你走了。另我告诉你强调我找到的过去完成式。FOUND和LOOK FOR表示找到的过去完成式FOUND可以表示一个状态。找到了就是。。如果换成LOOK FOR 那就不行了。LOOK FOR是瞬间的就是找。不能表示找到的一个状态。其实过去完成时就是过去完成保持到现在的一个完成状态。你拿FOUND和LOOK FOR比比就知道了。。
I had taken the books before you arrived对。。强调在你来之前这个状态。我已经把书带走了。。
