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. 鈴壹響，下課了。教室裏熱鬧起來，壹些學生出了教室。當李紅向我走來時，我正和壹些同學聊天。她笑著對我說：“妳知道4減4等於幾嗎?”我回答：“等於零，太簡單了。”但李紅播著頭說：“不對，是8。”“為什麽?不可能。”李紅說：“妳砍掉桌予的4個角，就明白了。”“這是笑話嗎?”“喚，是的。”我們都笑-了。課間我們放松了。我們經常度過愉快的課間。
