现在完成时和过去完成时疑问句用法是什么

Question

How many times have you got there？
这里是完成时用法的哪一种？影响？

Answer 1

“How many times have you got there？”这应该是现在完成时的疑问句，问的是你去过那个地方几次。
现在完成时强调过去对现在的影响。
过去完成时指动作发生在过去的过去。比如“When he arrived the bus stop, the bus had already gone.” （昨天）当他到达公交车站时，公交早已走了。“走”的这个动作先于“到达”的这个动作，而这两个动作对今天来说都是过去了的，所以“走”的动作可看成过去的过去

你好，很高兴为你解答。
保证正确率~！

【答案】：
现在完成时态的疑问句:Have /has+ 主语+动词的过去分词+...?
现在完成事时态的肯定句式: 主语+have/has+动词的过去分词+...
例如:1. She has finished her homework.
Has she finished her homework?
过去完成时态和现在完成时态的句式结构类似,只需把助动词have/has换成had即可.
例如;The film had been on when we arrived there.
Had she cleaned the room when you got home yesterday?
这两中时态的特殊疑问句式也类似.就是在他们的一般疑问句的基础上加上适当的特殊疑问词.
例如：What has she said to you ?
What had they brought to us when they came yesterday?
