关于after的过去完成时用法
"Mr Hussein also denied a report in the Wall Street Journal that the plane had sent engine data to the ground for more than four hours after it lost contact with air traffic control."
其中“ after it lost contact with air traffic control”为什么lost不是用过去完成时,而是过去时?

答案

在含有after或before的时间包括状语从句的句子中,一般是可以用一般过去时代替过去完成时的.
如：
The film began before he went into the cinema.
=The film had begun before he went into the cinema.
He laughed after he heard the story.
=He laughed after he had heard the story.
