Question

【题目】You have to explain________.

A.that you didn’t go to school yesterdayB.why you didn’t go to school yesterday

C.where did you go yesterday

Answer 1

【答案】B

【解析】

句意：你必须解释你昨天为什么不去上学

考查宾语从句。由空前explain可知，空处是宾语从句。that引导宾语从句无词义，选项A“你昨天没上学”不符合句意，故排除；宾语从句应用陈述句语序，选项C是疑问句语序，故排除。选项B是疑问词why引导宾语从句，意为“你昨天为什么不去上学”，符合句意。故选B。
