甲、乙、丙三人有如下对话，其中每人有一条信息是错误的，甲说：“我23岁，比乙小3岁，比丙大2岁，”；乙说：“我不是年龄最小的，丙和我相差5岁，丙是25岁，”；丙说：“我比甲小，甲24岁，乙比甲大2岁．”由此可以推断：甲______岁；乙______；丙______岁．
甲说甲23岁，而丙说甲24岁，那么两句中有一句错误；
假设甲说：“我23岁，比乙小3岁，比丙大2岁”中甲是23岁是错误的，那么甲比乙小3岁，比丙大2岁；乙就比丙大5岁；
乙说：“我不是年龄最小的，丙和我相差5岁”，中这两条与甲说的话对应，所以假设是正确的；
那么甲就是24岁；
乙是：24+3=27（岁）；
丙是：24-2=22（岁）；
故答案为：24，27，22．
I stood there listening to my father shout at top of his voice. The look on his face said that one of us did something . “Which one of you did this?” We all looked down at the step. There was child’s handwriting in chalk there. I had a lot of . I hoped no one could see it. Would he guess it was me? I was so worried. When he asked me, I lied, “Not me, Dad.” The others denied（否认）it as well. Of course, we all knew that one of must have done it. But as the youngest and smallest of the three, I just couldn’t find the courage to tell the truth. To who had written on the step, Father gave us each a piece of paper and a pencil. “I want each of you to exactly what you see on the step.” I tried my best to write the words . I didn’t want Dad to be able to tell it was me. He our pieces of paper and looked at them. “Since none of you will admit (承认) to have done it, then I will punish (惩罚) you and said nothing. The last thing I wanted was for Dad to me. “I did it.” My sister said she did something that she didn’t. Father grounded her for a month. We didn’t talk about that day for many years. Not until we were all older and I knew it was to finally tell my dad it was really me. I always felt sorry for it. That was the last time I let anyone take the blame (责备) for me.
