Not until many years later _____ known.
A. was the whole truth become
B. did the whole truth become
C. the whole truth became
D. the whole truth had become
题目解答
答案
B. did the whole truth become
解析
本题考查倒装句的用法，特别是Not until引导的倒装结构。当not until位于句首时，主句需要使用部分倒装，即助动词/情态动词+主语+谓语动词。解题关键在于识别倒装结构的正确形式，并注意时态的匹配。
选项分析
选项B（did the whole truth become）
- 倒装结构正确：助动词
did提前，主语the whole truth后置，符合部分倒装规则。 - 时态正确：
become为动词原形，与did构成一般过去时，符合句意“多年后才被知晓”。
其他选项错误原因
- 选项A（was the whole truth become）：
become应为过去式became，且was与become搭配不当。 - 选项C（the whole truth became）：未使用倒装结构，不符合语法要求。
- 选项D（the whole truth had become）：
had become为过去完成时，但句中时间状语many years later表明是一般过去时事件，时态错误。
