　　请看两道题：
　　(1) 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
　　答案为D。此题考查not…until…句式的强调形式——It was not until…that…的用法。注意不要想当然地将其中的that换成when。
　　(2) It was not until she got home _______ Jennifer realized she had lost her keys.
　　A. when B. that
