问题补充：
--Why didn’t you take part in the school reunion （团聚、重聚）yesterday?
--I’m sorry, but not until last night of it.
A. did I tell
B. was I told
C. I was told
D. I had told
答案：
A. did I tell
(答案→)B. was I told
C. I was told
D. I had told
解析：考查时态及主谓倒装。句意：昨天你为什么不参加学校团聚呢？——抱歉，直到昨晚才有人告诉我。结合语境可知下文描述的是过去的状态，故用过去时态。我是被告知对象故用被动语态的，当not until位于句首时，主句用部分倒装，故选B。
