Question

【题目】I wonder ________ at 9:00 last night? You didn't answer my telephone．

A.what were you doingB.what did you do

C.what you were doingD.what you are doing

Answer 1

【答案】C

【解析】

句意：我想知道昨晚九点你在做什么？你没接我的电话。

考查宾语从句语序。what were you doing你正在做什么，过去进行时的疑问句形式；what did you do你在做什么，一般过去时的疑问形式；what you were doing你在做什么，用于过去进行时宾语从句；what you are doing你在做什么，用于现在进行时的宾语从句。根据时间状语“at 9:00 last night”，可知是过去进行时。选项A和C都是过去进行时，按照宾语从句的陈述语序，选项C符合题意，故选C。
