In the early morning of winter, a father and son climbed Yandang Mountain to watch the sunrise. The child is very young and will get tired if he doesn't walk for a while. At this time, there is still a distance from the top of the mountain, so the father took off his coat, carried the child on his back (bè i bê i) and carried the child up the mountain. The biting cold wind blew violently, and my father climbed to the top of the mountain step by step. Father is like a wall, blocking all the cold wind.

Finally reached the top of the mountain, and the golden sun was rising slowly from the east. The child fell asleep in the turbulence, and his father gently woke him up and said excitedly, "Come on, look forward!" " The child woke up from a dream and looked up reluctantly. Ah! He saw the round sun ahead, and the whole world was a rose-like red!

That child is me, and suddenly I have become a middle school student. "Looking forward" is my father's request and my father's hope. I got 99 points in a math exam, ranking second in my class. I am very proud. My father found out and patiently enlightened me: "There is no end to learning, and knowledge is never too old to learn." [] You did well in the exam this time, [] is only the second in your class. "I was a little unconvinced and said," The last question is too difficult. The teacher said that you can do an additional question without doing it. " Father seemed a little angry, but he restrained himself and said (angrily and coldly), "Why can't you do what others can do?" "You have to work hard, there are mountains outside the mountain, and there are people outside the person. Even if you win the first place, you will only be in the class and look forward. "

The sentence "look ahead" reminds me of my father carrying me up the mountain to watch the sunrise when I was a child. ...

Yes, looking forward, there is hope and a bright future like the sun.
