今天上午我上数学课的时候我的牙掉了，所以我把它吐出来放到手里，我跟蔺老师说：“老师，我牙掉了”，蔺老师说，掉就掉吧，也该换新牙了。我看了看，我感觉我的牙太小了，而且我看着牙有点白，突然，牙掉到地上找不到了，我把我的牙弄丢了，我希望我能长出更漂亮的牙。
I lost my teeth in my math class this morning, so I spit it out and put it in my hand. I said to Lin, "teacher, I lost my teeth." Lin said, "just drop it, and it's time to replace it.". I saw it. I felt that my teeth were too small, and I saw that they were a little white. Suddenly, my teeth fell to the ground and I couldn't find them. I lost my teeth. I hope I can grow more beautiful teeth.
