Mrs Brown went to visit one of her friend and carried a small box with holes punched in the top.

　　

　　" What's in your box?" asked the friend.

"A cat," answered Mrs Brown. "You see I've been dreaming about mice at night and I'm so scared! This cat is to catch them."

　　

　　"But the mice are only imaginary," said the friend.

　　

　　"So is the cat," whispered Mrs Brown.

　　

　　布朗太太去看朋友时，拎了个小盒子，盒顶上扎了些洞眼儿。

　　

　　“你这盒里装的啥呢？”朋友问。

　　

　　“一只猫。”布朗太太说，“你知道不？我晚上总梦见老鼠，特别害怕！这猫是用来抓老鼠的。”

　　

　　“可这老鼠只不过是想像中的呀。”朋友说。

　　

　　“这猫也是。”布朗夫人悄声地说。
