The master, to impress on his pupils the need of thinking before speaking, told them to count fifty before saying anything important, and one hundred if it was very important.

老师为了让学生记住先思考后发言，告诉他们在说出重要事情之前先数到50，如果是特别重要的事情，要先数到100。

The next day he was speaking, standing¹ with his back to the fire, when he noticed several lips moving rapidly. Suddenly the whole class shouted: Ninety-eight, ninety-nine, a hundred. Your coat is on fire, sir!

第二天，当老师背靠着火炉讲课时，发现好几个学生的嘴唇在很快地不停地动。突然，全班学生一起喊道：“九十八，九十九，一百。老师，您的大衣着火了！”
