A fourth-grade teacher was giving her pupils a lesson on logic.

　　"Here is the situation," she said. "a man is standing up in a boat in the middle of a river, fishing. He loses his balance, falls in, and begins splashing and yellin
g for help. His wife hears the commotion, knows that he can't swim, and runs down to the bank. Why do you think she ran to the bank?"

　　A girl raised her hand and asked, "to draw out all of his savings?"

　　逻辑推理

　　小学四年级的教师正在给学生们上一堂逻辑课。她举了这么一个例子：“有这样一种情况，一个男人在河中心的船上钓鱼，突然失去重心掉进了水里。于是他开始挣扎并喊救命。他的妻子听到了他的喊声，知道他并不会游泳，所以她就急忙跑向河岸。谁能告诉我这是为什么？” 一个女生举手答道，“是不是去取他的存款？”

　　[注]bank在英语中除了我们平时很熟悉的“银行”之外，还有“河岸”的意思。
