今天，我在做手工的时候，把纸丢在地上。妈妈摇摇头的说：“乱丢垃圾是不好，不仅破坏环境，还养成了一个坏习惯。”我听妈妈的话马上把纸捡了起来扔进垃圾桶。
Today, when I was doing the handwork, I left the paper on the ground. Mother shook her head and said, "it's not good to litter. It's not only damaging the environment, but also forming a bad habit." I picked up the paper and threw it into the dustbin.
妈妈说：“ 这才是我的好孩子嘛！”我高兴的笑了。我心里想我一定要做个讲卫生的好孩子……
