China, a proud surname, has a long history. From ancient ancestors Yan Di and Huangdi to modern civilization, * * * has experienced more than 4,000 years. Among them, I don't know how many China heroes have emerged: the patriotic general Yue Fei, a generation of arrogant Genghis Khan, Hua Mulan who joined the army for her father, Zhao Jun who fought for peace between the two countries, and Mu, who was brave and good at fighting. Many great inventions in history are the crystallization of our ancestors' wisdom: Cai Lun's improved papermaking, Zhang Heng's seismograph, Hua Tuo's hemp boiling powder, and the great mathematician Zu Chongzhi's discovery of pi have all made great contributions to the development of science today. Today's "China" economy is very developed, the economy is increasingly prosperous, and people's living standards are getting better and better. Especially in the past 20 years of reform and opening up, every household has become rich, both in urban and rural areas. In the city, almost every family has a computer, and many families have bought cars. Every holiday, the city is brightly lit and bustling. The changes in the countryside are even greater. Farmers have learned to plant scientifically, and their annual income is several times, ten times or even hundreds times that of the past. Many families built small buildings, bought fashionable furniture and used modern facilities, and the farmers laughed from ear to ear. Many large companies not only develop well at home, but also enter foreign markets and set up branches abroad. Many well-known foreign enterprises are also optimistic about the China market and have set up multinational companies in China. With the improvement of living standards, people's quality has also improved. Since bidding for the Olympic Games, people have learned English again, so foreigners should see the friendliness of China people at the 2008 Olympic Games. Nowadays, people who can't speak English are semi-illiterate, and learning a foreign language seems to be a fashion. China is constantly developing and progressing. Teenagers in China also have the spirit of progress and hard work. As far as the Olympic Games just ended, China sent many young athletes to participate. Although many of them are competing for the first time and are very young, they are brave enough to fight, and the strength of their opponents has aroused their fighting spirit. No matter whether you are ahead or behind, you win without arrogance and lose with grace. They fought hard and won 32 gold medals for China, ranking second in the world. Watching the five-star red flag rise again and again in Ran Ran, Athens, my heart also rises again and again with the five-star red flag. I feel very proud and excited. I think: As teenagers in China, we should all have the spirit of tenacious struggle and not giving in to difficulties. Whether in the Olympic Games or in a certain test of life, we should give full play to the enterprising spirit of young people in China. Teenager is a dynamic term. Yes, we are teenagers, we are teenagers in China, we are flowers and hopes of the motherland, and we have plenty of time and energy. In China, a country with a long history, civilization, high quality, developed economy and leading technology, what a great task we shoulder, but I believe we will live up to expectations, work hard and make continuous progress. Now, we should cherish the precious study time at school, strive to learn scientific and cultural knowledge well, and contribute our own strength to the construction of the motherland in the future. Yes, my last name is China, and I am very proud of my name.
