放学后，小红走到教学楼旁边，刚好有一块西瓜皮砸到她头上，随后她又看到掉了三块。小红说：“这是谁不爱护环境呀。”她抬头一看302房间的窗户开着，就找到302家问个明白。
After school, Xiaohong went to the teaching building, just a watermelon skin hit her head, and then she saw three pieces fall. Xiaohong said, "who doesn't love the environment?" She looked up and saw that the window of Room 302 was open, and then she found 302 houses and asked them to understand.
听到敲门，小明马上去开门，一看是小红赶快让进屋。问：“有事吗？”小红把西瓜皮放在桌子上说：“是你扔的吗？”小明说：“是的。”小红说：“以后不要这样做了好吗？”小明说：“我知道错了，以后要改正。”
At the knock, Xiao Ming immediately opens the door. At first sight, Xiao Hong lets her in. "What's the matter?" Xiaohong put the watermelon skin on the table and said, "did you throw it?" Xiaoming said, "yes." Xiao Hong said, "don't do this in the future, OK?" Xiaoming said, "I know I'm wrong. I'll correct it later."
小红要走，小明说：“别走啊，吃点西瓜吧。”小红说：“不吃了，我还要回家吃饭呢。”回家后她把这件事告诉了妈妈，妈妈很高兴，夸奖小红董事了，小红心里很高兴。
Xiaohong wants to go. Xiaoming says, "don't go. Have some watermelon." Xiao Hong said, "no, I'm going home to eat." After going home, she told her mother about it. She was very happy. She praised Xiaohong's director. Xiaohong was very happy.
通过这件事，小红和小明成为了好朋友。
