今天妈妈带我去买尺子时，我把商店门口的“旱冰鞋”读成了“早冰鞋”，商店里的阿姨哈哈笑了起来，我认真地看了又看，才知道读错了，是“旱冰鞋”，这才不好意思地低下了头。
Today, when my mother took me to buy a ruler, I read "roller skates" at the door of the store as "morning skates". The aunt in the store laughed. I read and read carefully, and then I knew that it was "roller skates". I lowered my head embarrassed.
这件事情让我懂得了做任何事情都要认真、仔细，不能马马虎虎。
This has taught me to be serious and careful in everything I do, and not to be careless.
