Question

— Sally, our monitor, was late for her class this morning.
— ______? As far as I know, she never came late to class.

A．How come

B．What for

C．So what

D．Why not

Answer 1

A

试题分析：考查交际用语：How come=怎么会这样？ so what=这有什么关系？ why not= 为什么不？ what for=why，句意：---sally,我们的班长今天早上上课迟到了。--怎么回事？据我所知，她从不上课迟到的。选A。
点评：交际用语的考查要根据上下文的语境进行，对于一些重要的交际用语要加强识记和理解。本题的四个选项都是常考的交际用语，一定要加强识记。
