题目内容
【题目】Not until she took off her glasses ______ she used to be my neighbor.
A. I realized B. I had realized
C. had I realized D. did I realize
【答案】D
【解析】
试题分析:考查部分倒装句型。该句为倒装句型,原句为:I didn't realize she was a famous film star until she took off her dark glasses.时间状语“not until+时间”结构提前到句首时,主句部分倒装.再根据主从句时态判断,得提前表过去的助动词did.句意为直到他取下眼镜我才意识到他曾经是我的领居。故选D。
