Question

—What were you and your father doing at 7:00 yesterday evening?

—I was doing my homework ________my father was reading newspapers.

A.when B.as soon as C.while D.if

Answer

C

【解析】

句意：——昨天晚上七点钟的时候，你和你的爸爸正在干什么？——当我在做我的作业的时候，我爸爸正在看报纸。

考查连词辨析。when当……时候；as soon as一……就……；while当……时候，与……同时；if如果。根据句中“I was doing my homework”和“my father was reading newspapers”可知，我写作业和我爸爸看报纸是在同一时间段内发生的延续性动作，所以此处使用while引导。故选C。
