34页60.The book was so interesting that he had read it for three hours -------he realized

34页60.The book was so interesting that he had read it for three hours -------he realized
A.when B.until C.after D.before 为什么

Answer 1

正确答案应该是until，在他明白这本书非常有趣之前，他已经读了3个小时了

或者说，当他读了3个小时后他才明白这本书很有趣

你把后面那句放到前面就明白了：

He realized the book was so interesting until he had read it for 3 hours

或者是He had read the book for 3 hours until he realized it was so interesting

因为他意识到的东西只能是“这本书很有趣”而不可能是“他已经读了3个小时了”如果选before,那么前面那句的强调结构变成了因果关系，那么那句"he realized"再加在句子后面就明显不合理了

Answer 2

选D，我不是很明白，when一般表示一种伴随状态，after跟时间吧，untill嘛，一般是要怎么样之后才能怎么样的时候用，我学的也不好，呵呵

Answer 3

选：D。意为：这本书是那么有趣以至于在他意识到。。。之前，他已经看了3个小时。

Answer 4

选D 按照意思来分析 在她意识到之前

若是选B的话 前面要有 NOT
