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.爸爸出差回來(lái)給莉莉買(mǎi)了一份禮物，但是爸爸沒(méi)有直接把禮物送給她，而是給她出了道難題。

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?爸爸在桌子上擺了3個(gè)盒子：一個(gè)紅色盒子，一個(gè)綠色盒子，還有一個(gè)黃色盒子。每個(gè)盒子都寫(xiě)著一句話，但只有一句話是真話。你能夠猜出禮物裝在哪個(gè)盒子里嗎？

因?yàn)榧t盒子和黃盒子上的話正好截然相反，所以其中必然有一句是真的，那么綠色盒子上的話就是假的。
