46、 Cwhat Dwhen 答案与解析：B考查同位语从句的用法。由于句中出现插入语，导致判断失误。可以把句子语序调整为“But believe it or not，I still remember the story _ we got lost on a rainy night”，这样就容易判断出“_ we got lost on a rainy night”是解释story的具体内容，是同位语从句，不是定语从句，可以排除A和D。同位语从句句子成分齐全，所以选择B。本题容易误选其他答案，主要是对句子结构没分析到位。 19A man who purchased _ he thought was an expensive dog was shocked to learn recently that this pet was actually an arctic fox. Athat Bwhich Cit Dwhat 答案与解析：D考查名词性从句。根据题意：一个人买了只狗，原以为是名贵品种，最近却惊讶地得知，这只宠物狗实际上是一只北极狐。what引导的宾语从句作purchase的宾语，在从句中作主语成分。本题的迷惑点是he thought，作插入语，对整个句子成分没有影响。that在引导名词性从句时，在从句中不作成分，所以不能选A。
