A little girl was failing math. Her mother enrolled her in Catholic school in the hopes to improve her math grades. During the first marking period, her mother was astonished to see that her daughter got an A+ in math. She asked her daughter, “Why the sudden change of attitude about math -- do the nuns punish you?” The girl replied, “No, but when I saw the little man on the wall nailed to the plus sign, I knew that this school is very serious about math!”
要求
一个小女孩数学不及格。她的母亲将她转到天主教学校，希望她的数学成绩有进步。在第一个学期，她母亲很吃惊地看到女儿数学竟得了A+。她问女儿：“为什么数学成绩有如此大的进步——是修女强逼你吗？”女孩说：“不是的，只是当我看到墙上有一个小男人被钉在加号上，我就知道这里对数学要求很严厉。”
nun n. 修女， 尼姑
