命题意图：本题主要考查连词的语意，但需结合时间，尤其是前后两个动作发生的先后顺序，故难度较大。本题属五星题。
知识依托：as 引导时间状语从句，意思是当……时，since 自从，until直到……，before在……之前。答案选D。
错解分析：错误的原因在于没有了解相关动作发生的先后关系，they hung up发生在I could answer the phone之前，题目的意思是：半夜里有人给我打电话，但我还没来得及接/在我能接电话之前，他们就挂掉了。
解题方法与技巧：解关于从属连词的题首先要了解各自的语意；在处理习题时，还要结合上下文的语境和结构来进行综合确定。
答案：D

●锦囊妙计
1.为使用好连词，首先应了解连词可能出现的情况。并列句和复合句中，尤其是复合句中的连词，他们通常可分为：
从属连词：that(无意）,before,whether, if, after, since,as long as,when
连接代词：who, whom ,which, what, whose
连接副词：when ,why, where ,how
关系代词：who, whom ,whose, which, that
关系副词：when, why ,where
2.状语从句均用从属连词引导。
3.语意理解是关键。
