Early in the morning, I walked in the park with my head down. I'm tired of weekend homework. There are too many math problems, so I choose to give up.

As always, the sun shines everywhere, and it is not dim because of my giving up. It seems that I was right to give up. The sunlight reflected on a smooth stone wall, and the subtle bright spots aroused my curiosity: what is that? I walked quickly past.

A small snail, accompanied by sunshine, moved its small body and rushed to the top of the stone wall. It went on quietly and failed once, twice and again. I stared at this little shell silently and shook it. He should give up, but I can't stop it. What a fool! Doesn't it feel that the sun is laughing at it mercilessly? "This will never work," I thought silently as I walked home. "Like me, I will never succeed."

At night, I flew out of the house and couldn't wait to see how the snail was and whether its little shadow had given up. I hurried to the stone wall and looked for it carefully, but I couldn't see the shadow of the snail. It seems that it really gave up. I turned around and my eyes suddenly saw the shiny shell, which was on the top of the stone wall. Suddenly, I realized that I was wrong. The sunshine didn't support me or laugh at me. It always regards sunlight as the driving force.

As the sun sets, the sun shines on the snail for the last time. She slowly climbed into the grass and entered the end of her dream. I seem to see its imprint and sweat. It turns out that this is the snail's way that I have been learning. I walked home with my head held high. Here I am, a math problem. Even without sunshine, I won't be defeated by you.
