"You have found your lost umbrella,haven't you?" "Yes,I found it behind the door this morning."为什么答语中"found"不用"have found"?

问题描述:

"You have found your lost umbrella,haven't you?" "Yes,I found it behind the door this morning."
为什么答语中"found"不用"have found"?

答语中有个this morning的时间状语,用一般过去时表示在过去的某个时间发生的事情。have found是现在完成时,不能和过去的时间状语连用。可以说I had found it behind the door this morning.但言语中有些不耐烦或高傲

答语中的this morning是过去的时间,故用一般过去时,而不用现在完成时.
