Daddy bought a gift for Lily after his travel out on business.But her daddy didn’t give the gift to her immediately.He just offered her a puzzle.爸爸出差回来给莉莉买了一份礼物，但是爸爸没有直接把礼物送给她，而是给她出了道难题。

There were three boxes on the table：one is red,another green and still another is yellow.On each box there was a sentence,but only one of them was correct.Could you find out in which box the gift was contained?爸爸在桌子上摆了3个盒子：一个红色盒子，一个绿色盒子，还有一个黄色盒子。每个盒子都写着一句话，但只有一句话是真话。你能够猜出礼物装在哪个盒子里吗？

因为红盒子和黄盒子上的话正好截然相反，所以其中必然有一句是真的，那么绿色盒子上的话就是假的。
