美國流行笑話：What did the sign say? 那標牌上寫的什么字？

What did the sign say? 那標牌上寫的什么字?

In the doctor's waiting room I saw a mother helping her little boy sound out the words on a sign. Finally he mastered it and his mom cheered, “That's great! Now sit there. I'll be back in 15 minutes.” What did the sign say? “Children must not be left unattended.”

在醫(yī)生的候診室里我看到一個母親正在教她的小男孩讀一個標牌上的字。最后，小男孩學(xué)會了。母親高興地說：“太棒了!現(xiàn)在你坐到那兒，我過15分鐘回來。”那標牌上寫的什么字?“孩童不可無人照看。”
