A解析试题分析：考查主语从句。本题中where引导主语从句，并在句中做地点状语。句意：他一句话没有说就离开了家，他去了那里这让很多人很担心。任何一个主语从句都要使用陈述语序，排除BCD三项。故A正确。考点：考查主语从句
点评：所有的名词性从句都要使用陈述语序，在复合句中做主语的从句叫做主语从句，它的位置与陈述句基本结构中的主语相同。引导主语从句的关联词有：连词：that, whether；连接代词：who, whom, whose, what, which；连接副词：when, where, why, how；复合词：whatever, whoever, whomever, when?蛳ever, wherever, whichever, however.解答这类题目，关键在于分析清楚句子结构。通过判断引导词在从句中所作的成分及意义，来选择正确的引导词。
