今天，轮到做事细心的小红、全班成绩最好的兰兰和手脚笨拙的笨笨做值日了。瞧，她们做得多认真呀！兰兰用心地扫着地，生怕漏扫了一个角落。小红把窗户擦得干干净净，都可以照出人影了。笨笨看见讲台上很脏，于是拿来起抹布擦了起来。
Today, it's the turn of Xiao Hong, who is careful, LAN LAN, who is the best in the class, and the clumsy one who is clumsy. Look, how seriously they do it! Lan Lan carefully sweeps the ground for fear of missing a corner. Xiao Hong cleans the windows so that people can be seen. Benben saw that the platform was dirty, so he took a rag and wiped it.
在擦讲台的时候，笨笨的抹布碰到了墨水瓶，只听“嘣”的一声，墨水瓶被打翻了。她们仨人都吓得目瞪口呆。过了一会儿，他们才回过神来，笨笨见势不妙就跑去叫老师了。兰兰拿起抹布想要用抹布擦掉墨水，可墨水太多了，抹布都被染黑了，还是擦不干净。小红灵机一动心想：“海绵的吸水性不是很好吗，用它来擦一定行。”于是，小红拿来海绵擦起来。可这事也真神了，小红两三下就把墨水擦干净了。他们又用拖把把地上的墨水拖干净。看着干净的讲台和地面，她们心中的一块石头才落了地。
While cleaning the platform, the stupid rag touched the ink bottle, and only heard a "bang". The ink bottle was knocked over. All three of them were stunned. After a while, they came back to their senses. They were stupid and ran to call for the teacher. Lan Lan picked up the dishcloth and tried to wipe off the ink with the dishcloth, but there was too much ink, and the dishcloth was dyed black, which was still not clean. Xiaohong thought: "isn't the water absorption of sponge very good? It's OK to wipe it with it." So Xiao Hong took a sponge and wiped it. But it's amazing. Xiao Hong wipes the ink two or three times. They mop up the ink on the ground again. Looking at the clean platform and the ground, a stone in their heart fell to the ground.
这时，老师和笨笨也走进了教室，老师望望讲台，又望望地面，奇怪地问：“讲台不是好好的吗？哪有什么墨水瓶被打翻的痕迹呢？”听了这名话，小红和兰兰低下头，偷偷笑了。
At this time, the teacher and Benben also came into the classroom. The teacher looked at the platform and the ground, and asked strangely, "isn't the platform good? Where are the marks of the ink bottle being knocked over? " Listening to this, Xiao Hong and LAN LAN look down and smile secretly.
