题目内容
When asked to explain ________ made his lessons so exciting, the teacher kept silent.
A. what it was thatB. that what it was
C. what was it thatD. that what was it
A
【解析】
试题分析:句意:当被要求解释是什么让他的课使学生这么兴奋的时候,这个老师保持沉默。这句话中explain后面是宾语从句,宾语从句后缺成份,并且是做主语的物(做主语、宾语、表语,),那要用what引导(如不缺成份用that),而且是强调句的特殊问句:is/was it…that…,那宾语从句中的疑问句要用陈述语序,因此是A。
考点:考查宾语从句和强调句
