【英文原文】
What a rat looked like——老鼠是什么样子的
Rodents had overrun a posh private school near New York City. So the headmaster, a friend of mine, asked a health inspector to deliver a slide presentation to teachers and students, showing how to remedy the situation, i.e., stow trash, no food in class, etc.
The following day, a teacher had her very young children write a letter to the inspector, thanking him for the visit. One of the students wrote, "Dear Mr. Johnson, Thank you for coming to my school. Until I saw you, I didn't know what a rat looked like."
