今天早上数学课上，我们进行了第一次数学考试，我得了98分，没有得到100分，有点遗憾。
In this morning's math class, we had our first math exam. I got 98 points, but I didn't get 100 points. It's a little pity.
在放学的路上，我告诉妈妈今天考试的事情。妈妈问我哪儿做错了，我告诉妈妈后，妈妈没有说我，让我下次要细心点儿。
On the way to school, I told my mother about the exam today. My mother asked me what I did wrong. After I told her, my mother didn't say that I was wrong. Let me be more careful next time.
我一定会努力的。
I will try my best.
