knocked at the door again and again 未完成的动作knocked at the door again and again 与but on one reponded.是并行事件

敲门是作为一个动作出现的,并不是一个状态.而且but前后的knock和respond动词是相对应的,时态应该一致.不妨假设按过去完成时做下调整,大概你也会看着别扭了吧I had knocked at the door again and again ,but on one had reponded.个人观点,日常英语不是说什么什么一定不行,只不过可能有更好的选择罢了.大陆的英文教育也就那么回事.
