The original text is as follows

My grandmother died when I was in primary school. My grandmother loved me the most before her death. I can't rule out my sadness. I run round and round on the school playground every day, so tired that I fall to the ground and cry on the lawn.

That sad day lasted for a long time, and my parents didn't know how to comfort me. They know that instead of lying to me that grandma is asleep, they might as well tell me the truth: grandma will never come back.

"What is never coming back?" I asked.

"Everything in time will never come back. Your yesterday has passed, it will become yesterday forever, and you can never go back to yesterday. Dad used to be as young as you, and now he can't go back to your childhood. One day you will grow up, you will be as old as your grandmother, one day you will spend all your time, and you will never come back like your grandmother. " Dad said.

Dad told me a mystery, which made me feel terrible than "an inch of time is worth an inch of gold, and an inch of time is hard to buy with an inch of gold", and gave me an unspeakable taste than "time flies, the sun and the moon fly like a shuttle".

After that, I went home from school every day and watched the sun sink inch by inch in the courtyard, and I knew that the day was really over. Although there will be a new sun tomorrow, there will never be today's sun.

I see birds flying into the sky. How fast they fly. Tomorrow they will fly over the same route, and it will never be today. Maybe it's not the old birds that fly this route tomorrow, but the birds.

Time flies so quickly that my cautious eyes are not only anxious, but also sad. One day when I came home from school, I saw that the sun was going down, and I made up my mind to say, "I want to go home faster than the sun." I ran back and stood in the courtyard panting when I saw that the sun was still half exposed, and I jumped up with joy. I beat the sun that day. I often play such games in the future. Sometimes I race with the sun, sometimes I compete with the northwest wind, and sometimes I finish my homework in ten days in a summer vacation. At that time, I was in the third grade, and I used to do my brother's homework in the fifth grade. Every game beats time, and I am so happy that I don't know how to describe it.

in the next twenty years, I benefited a lot from it. Although I know that people can never run beyond time, they can run one step faster than before, and sometimes they can run several steps faster if they work harder. Although those steps are very small, they are very useful.

If I have anything to teach my child in the future, I will tell him that if you keep racing against time, you can succeed.
