Question

【题目】—Were you worried about your son last night?

—Yes. It was________that I went to bed.

A.until he returnedB.until he did return

C.not until he returnedD.not until did he return

Answer 1

【答案】C

【解析】

考查强调句型。句意：昨晚，你担心儿子吗？是的，直到他回来，我才上床睡觉。通过分析句子结构可知，此处使用强调句型，强调部分为until引导的时间状语从句，因此将not移至until前。故选C项。
