The bell rang and the class was over. The classroom became noisy. Some students went out of the classroom. I was just chatting with some of my classmates when Li Hong came to me. She smiled and said to me, "What"s four minus four? Do you know?" "It"s zero. That is easy." answered I.
But Li Hong shook her head and said "It"s wrong. It"s eight." "Why? That"s impossible!" "You will understand if you cut down four corners of a desk." said Li Hong. "Is that a joke?" "Oh, yes." We all laughed. During the class break, we had a good rest. We often have a pleasant break.
铃声响了，下课了。教室变得嘈杂。一些学生走出教室。我只是和我的一些同学聊天，当李洪来到我的时候。她笑着对我说：“四减四？你知道吗？这是零。“很容易。”我回答说。
但李洪摇了摇头，说：“这是错误的。八，为什么？这是不可能的！”如果你把桌子的四角剪下来，你会明白的，“李洪说。”那是个笑话吗？”哦，是的，“我们都笑了。课间休息时，我们休息得很好。我们经常有一个愉快的休息。
