32、确选项都经过了命题人对原文信息的语义转换，两者存在表达上的差异。解答间接细节理解题时要仔细阅读题干，通过题干和选项中的关键词及其所提供的信息从原文中找到相应的信息(即定位)，然后把选项中的信息与原文中的信息进行比较和分析，准确理解，作出选择。在做间接细节理解题时，要做到“两关注”“一防范”。“两关注”是指关注正确选项的两个特征：一是同义词替换或释义，即把文中语言(词汇和句型结构)改头换面，来表达相同的意思；二是对文章信息的归纳和概括。“一防范”是指防范干扰选项的迷惑性，错误选项常使用诸如张冠李戴、无中生有、曲解文意、断章取义、颠倒是非、正误参半等方式来造成句意的改变。例如上文第9题中选项C中的was laughed at，是对文章信息When students in her class started calling Prisilla a boy的同义替换，同时要防范错选曲解文意的D项。
