Recently, our students from grade three to grade six took a math test. I only got 92.5 points in this exam. Carelessness made me do a lot. You're right. It's not that I can't. It was careless. There are often some size problems. Without these problems, I would be better. There is a saying: "The first mistake may be excusable, but the second mistake shows that you are a' fool'." Maybe I am this "idiot". My grades are like an olive. Olives hang from the cliff. If you are not careful, you will "bump into …" and fall down.

Achievement depends not on thinking high, but on hard work. An ideal without action is a fantasy. As Nietzsche said, the value of a thing sometimes depends not on people's income, but on people's efforts-on how much you have paid for it. This sentence is correct. Wisdom does not lie in profound knowledge. We can't know everything. Wisdom lies not in knowing as much as possible, but in knowing what we need most and what we don't need to know.

Through this exam, I not only tested what I have learned recently, but also exposed many shortcomings of myself, so that I can correct them in time in my future study.
