单选题 When asked to explain _____ he did to make his students so fascinated with his lessons, the teacher paused and thought deeply.A.what was it thatB.that what it was C.what it was thatD.what was it

C解析试题分析：考查强调句的特殊问句做宾语从句：强调句的特殊问句结构是：特殊疑问词+is/was+that+其余部分。这里的强调句是做explain的宾语从句，所以语序是陈述句。句意：当被要求解释他做了什么让学生对他的课这么着迷的时候，这个老师停下来沉思。选C。考点：考查强调句的特殊问句做宾语从句点评：强调句型在高考中每年必出，关键是要会判断，平时练习时要有这个意识。it is /was+被强调部分+that/who+…判断方法是去掉it is /was that/who句子不缺成分，即为强调句型。还要熟记强调句的特殊问句和一般问句，再者注意强调句的特殊问句做宾语从句的语序问题。
