Learning is an indispensable thing in our long life. However, what is learning for? Is it for your own glory, for the family's reputation, or for the country's prosperity? Maybe both. But in any case, you should make your own efforts in your study. Only by persistent efforts can you succeed tomorrow. Let's talk about the second semester of the second grade. Our school held a math culture festival with colorful activities, including math tabloid painting, interesting math contest and math fairy tale contest. On second thought, I am not good at writing mathematical fairy tales, let alone competitions, but I am determined to apply for a project. I said to my math teacher, "I want to draw in the math tabloid." The teacher thought for a moment and said, "All right." When I got home, I said to my father, "Our school holds a math culture festival, and I want to participate in the math tabloid painting." Dad said, "What, you usually paint so ugly, and you also take part in the painting competition." I begged my father again and again, and my father finally agreed when he saw that I was so determined. I took out a lot of math tabloids for reference. I looked everywhere. Finally, I know what to do. But I accidentally made a big hole when I was drawing, which was really unlucky. I have to make another one. After writing, I picked up this tabloid with satisfaction. Ah, it's really beautiful. I handed in this illustrated book, "Many things grind", and the result came out. Seeing my name on the bulletin board, I turned my eyes to the right again. It was the second prize! I jumped three feet for joy. When I got home, I told my father the good news, and my father was very happy. I learned a truth from this competition: as long as we persist and work hard towards our goals, we will certainly succeed. My ultimate goal: to contribute to the country and fight the American devils. I believe that students must be familiar with the iphone. Since its launch, it has been favored by many people, even my mother and sister have used iphone. This leads to a thought-provoking question. The iphone was developed in the United States and caused a sensation in China. Why is this? Because of its high technology content, China can only do OEM for it. Therefore, our generation should study hard, explore diligently, strive to improve the level of science and technology, March to the destination, open up a blue sky of their own, and fly freely under the blue sky.
