题目内容
【题目】Alice didn’t know ____________ made her lose her patience and shout at her brother at that time.
A. what was it that B. what it was that
C. why was it that D. why it was that
【答案】B
【解析】
试题分析:考查宾语从句和强调句型。根据分析可知know后面接的是一个宾语从句且是一个陈述语气的强调句。陈述句的强调句型:It is/was+被强调部分(通常是主语、宾语或状语)+that/who(当强调主语且主语指人)+其它部分。置于动词、介词等词性后面起宾语作用的从句叫宾语从句, 其通常由连词that和whether(if)、连接代词或连接副词以及关系代词what引导。句意:爱丽丝不知道到底是什么让她在那时失去耐心,对着她的弟弟大叫起来。故选B.
