The story was so interesting that she had read it for three hours ___ she realized it.
A.when B.before C.after D.until
这道题的答案是选B，为什么不选A呢？

Answer 1

就是B 这是一个完成时态的句子。had done sth before sb did,在某人还没有来得及做某事之前就已经。。。。。意思是在他还没有意识到之前，他已经读了三个小时了

Answer 2

有语法 这是完成时
学英语语感很重要 语感好的人读这句话就知道选B

Answer 3

WHEN 是个表瞬时状态的时间状语。。但是had read是完成时态 是持续的动作 所以不能选A

Answer 4

翻译出来是~这个故事如此有趣以至于她读了3个小时才意识到。
had read 过去完成时 发生在realized 之前，所以用before~

Answer 5

你根据语义来，she had read it for three hours _she realized it .应该是说在他意识到之前，他已经看了三个小时了。要是选a就应该是she had been read it for....

Answer 6

今天前面已经是过去时了，所以要用before
