选择题
——Do you know Anna’s telephone number?
——____. As a matter of fact, I don’t know any Anna, either.
A．I think so
B．I’m afraid not
C．I hope so
D．I’d rather not
答案
答案：B
在情境交际中考查替代省略. 为了使交际更加简洁明了，省使用替代省略。I’m afraid not 相当于I’m afraid that I don’t know Ann’s telephone number. 比如：It’s going to rain tomorrow. I think so.="I" think it’s going to rain tomorrow.
