题目内容
【题目】 --- Whenyou free last week?
--- Well, Ihave a free day because there was too much work.
A. did, didn’t
B. were; didn’t
C. were, wasn’t
D. did, wasn’t
【答案】B
【解析】试题分析：句意：-上周你什么时候有空？-我没有一天有空，因为有很多工作。did 助动词；were是be动词的过去式形式。根据句中的last week可知，这里说的是过去的事情，free是形容词，应跟be动词搭配，故第一个空用were；第二个空后have是实意动词，故用助动词构成否定句。故选B。
