【解析】
【详解】考查定语从句和强调句型。句意:秘密会议是在他曾经住过的那所房子里举行的。分析句子结构可知,第一空为定语从句,先行词为house,从句中不缺主宾表,缺少地点状语,所以用where,去掉it is和第二空,结构依然完整,所以第二空为强调句型,强调会议举行的地点,其基本结构为it is+被强调部分+that+其余部分,所以用that,故D项正确。
【点睛】分析定语从句关键抓住两点:第一、找准先行词;第二、看先行词在定语从句中所作的成分。先行词往往为名词或代词,如本题中先行词为名词house,再分析先行词house在定语从句中所作的成分,将先行词house带到从句中可知,从句中不缺少主语、宾语和表语,缺少地点状语,故确定第一空用关系副词where。判断强调句型的关键是去掉it is…that…意思依然清楚,结构依然完整,本题若去掉it is…that…即为In that house where he used to live the secret meeting was held,意思清楚,结构依然完整,所以第二空为强调句型,故确定第二空用that。
