问题描述:

It _____ we had stayed together for a couple of weeks___I found we had a lot in common.
第一空
A.was until B.wasn't until
第二空
A.when B.that
并说明原因谢谢

第一空选择B
Not until 固定搭配,意为直到...才
第二空选择B
此句若删除It was...that变为not until we had stayed together for a couple of weeks,I found we had a lot in common.仍成句,故为强调句,不是定语从句.
