回答：1.The lights went _____while we were having a party at my uncle’s
A. off B. over C. out D. away
答案为C,为停电之意,但是A为何不能呢???

语法上两个都对，但如果是自己刻意把灯关掉的就用A，意外断电则用C。按句意属意外，所以是C。

2.Mary was disappointed when she found out they had gone to the ball ____her
A. except B. except for C. without D. besides.
答案为C, 为何 A错呢???

语法上也只有C是对的。大家都去了，却没有把MARY带上的意思，所以MARY失望了。
