题目内容
Not until he left his home _____ to know how important the family was for him.
A.did he begin B.had he begun C.he began D.he has begun
【答案】
A
【解析】
试题分析:句意:直到他离开家,他才意识到家庭对于他来说是多么的重要。这里not until放在句首句子,这里的主句用部分倒装。根据主句的谓语动词用的是过去式可知这里空格处也应该用过去式,故选A。
考点:考查倒装的用法。
点评:本题难度适中。倒装句是高中阶段必须掌握的语法项目,它分为部分到装和全部倒装,情况复杂,需要考生熟记它们的用法。
即学即练:—How was the weather then?
—Hardly_____off the plane,when it started to rain.
A.I had stepped B.had I stepped
C.I stepped D.did I step
解析:B。hardly, seldom等否定副词位于句首作状语时,后面要用部分倒装,再由句意可知,选B。
