Not until Peter got home ______ that he had lost his keys.A.did he realizeB.he realizedC.had he realizedD.he had realized求区分
答案是A
当Not until位于句首时,句子要倒装.其结构为:Not until+从句/表时间的词+助动词+(主句)主语+谓语+.如: ①Not until the teacher came in did the students stop talking.直到老师进来学生们才停止讲话. ②Not until next week will the sports meet be held.直到下周才开运动会.
而这句话翻译过来就是：知道皮特回到家才发现钥匙丢了.
