今天，我在家里写作业。突然，本子写完了。我拿着5角钱到商店买本子。
Today, I do my homework at home. Suddenly, the book is finished. I took fifty cents to the store to buy a book.
我一路小跑来到商店，进门我就大声喊道：“拿一个语文本。”售货员阿姨仿佛没有听见，只顾招待其他顾客。这时，我才发现墙上写着“请用礼貌语言”。我立即用柔和的语气对阿姨说：“阿姨，请您帮我拿一本语文本，谢谢！”阿姨微笑地说问：“小朋友，怎么变得这么有礼貌了？”我的脸不由得羞红了。买了本子，我高高兴兴地回家了。
I trotted all the way to the shop, and when I came in I called out," take a Chinese book." The salesgirl's aunt didn't seem to hear it. She just entertained other customers. At this time, I found the words" please use polite language" on the wall. I immediately said to my aunt in a soft voice," Auntie, please help me with a Chinese book, thank you!" The aunt smiled and asked," how can you be so polite, little friend?" I can't help blushing. After buying the book, I went home happily.
回到家，妈妈问：“本子买回来了？”“嗯，买回来了。”我吞吞吐吐地答道。妈妈好奇地问：“怎么了？”我只好一五一十地把事情原原本本地告诉妈妈。妈妈听后抚摸着我的头说：“行，知错就改，就是好孩子。”
When I got home, my mother asked," did you get the book?"" Well, it's back." I replied haltingly. Mother asked curiously," what's the matter?" I had to tell my mother exactly what happened. After listening, my mother stroked my head and said," OK, if you know something wrong, you can change it. It's a good child."
通过这件事，我明白一个道理，知道错了没有关系，重要的是要及时改正错误，才是好孩子。从此，我改掉了不用礼貌用语的坏毛病。
Through this matter, I understand a truth. It doesn't matter if I make a mistake. It's important to correct the mistake in time, so that I can be a good child. From then on, I got rid of the bad habit of using rude language.
