选择题
The _______ look in her face suggested that she ________ it before.
A．surprising; wouldn’t know
B．surprised; hadn’t known
C．surprising; hadn’t known
D．surprised; shouldn’t know
答案
答案：B
考查词义辨析及时态。Surprising令人惊讶的，意外的，指物；surprised出人意料的，指人；句意：她脸上意外的表情显示她以前不知道这件事。表情为非人类的事物，故用surprising。从句描述的是过去某个时间点前已经完成的动作，故用过去完成时态。选B。
