English Original
The teacher asked her students in class: "If there are five flies on your desk and you kill one, how many will remain?"
"One," shouted a boy, "the dead one."
The teacher said: "You should know that there are still four not dead."
The boy replied: "I know, but they have flown away."
He is right. Arithmetic is one thing, but logic is another.

老师在课堂上问学生:“如果你的书桌上有五只苍蝇,你打死了一只,还剩下几只?”
“一只,”一个男孩大声说道,“就是死了的那只。”
老师说:“你应该知道还有四只没死啊。”
男孩回答说:“我知道,但它们已经飞走了。”
他是对的。算术是一回事,但逻辑是另一回事。
