【答案】

A

【解析】

試題分析： 1.當(dāng)Not until位于句首時(shí),句子要倒裝。其結(jié)構(gòu)為:Not until+從句/表時(shí)間的詞+助動(dòng)詞+(主句)主語(yǔ)+謂語(yǔ)+...。故排除BD，realize發(fā)生在had left 之后，故用一般過去時(shí)。 ②Not until next week will the sports meet be held.直到下周才開運(yùn)動(dòng)會(huì)。

考點(diǎn)：部分倒裝。

點(diǎn)評(píng)：當(dāng)Not until位于句首時(shí),句子要倒裝。

即學(xué)即練： It ______ we had stayed together for a couple of weeks ______ I found we had a lot in common.

A. was until; when B. was until; that C. wasn’t until; when D. wasn’t until; that
