小姑娘數(shù)學課本第六單元的內(nèi)容是學習克和千克。一天，克和千克斗起嘴來了，千克對克說：“你看我比你大這么多，像你這么小的單位能比上我嗎？”克不服氣地說：“我可以變成比你大和比你小的數(shù)，還可以變成和你一樣的數(shù)呢，當然是我比你厲害！”它們誰也說服不了對方，吵得面紅耳赤。

Unit 6 of the little girl's math textbook is to learn grams and kilograms. One day, gram and kilogram began to fight. Kilogram said to gram, "look, I'm so much bigger than you. Can a small unit like you compare with me?" "I can become a number larger and smaller than you, and I can also become a number like you, of course, I am more powerful than you!" said Ke They can't persuade each other. They quarrel red in the face.

就這樣一天，兩天，三天，它們吵個不停，可始終沒有結果。它們來到小女孩的桌子上，看見小女孩在作業(yè)本上寫數(shù)學等式：１千克＝1000克，它們都呆住了，原來是這樣的啊。原來它們誰也離不開誰，誰也不會比誰更強一些，應該是平等的。它們覺得又害羞又慚愧，不約而同的說：“對不起，我錯了。”

On such a day, two days, three days, they quarreled incessantly, but there was no result. When they came to the little girl's desk, they saw the little girl write the math equation in her homework book: 1kg = 1000g, and they all froze, so it was. It turns out that no one can be separated from them and no one can be stronger than them. They should be equal. They feel shy and ashamed. They all say, "I'm sorry, I'm wrong."

從此克和千克成了一對好朋友，一起玩耍，一起唱歌跳舞，可開心了。

From then on, Ke and kg became a good friend, playing together, singing and dancing together, which made them happy.
