题目内容
6．There used to be a boarding school there，_______？（ ）| A． | don't there | B． | didn't there | C． | isn't there | D． | doesn't there |
分析 过去在那儿有一个寄宿学校，是吗？
解答 答案：B
反意疑问句的构成：助动词/系动词/情态动词+主语（代词），前句是肯定，后句用否定；前句是否定，后句用肯定；根据There used to be a boarding school there，可知句子使用的是一般过去时，used是一个实意动词的过去式形式，所以后面的反意疑问句应该用助动词did，此题前句是肯定，用的是didn't there，故选B．
点评 本题考查反意疑问句，先弄清其构成，再根据前句来确定主语及肯定与否定．
