Hello everyone,My name is Jinming.Today,I am going to talk about China.Because I live in China and I am a Chinese.I am proud of being a Chinese.Because China has five thousand years of civilization.I know a lot about China.I know the Great Wall and the Beijing-Hangzhou Grand Canal.I know the Yellow river and the Yangtze river I know the four great inventions made by our ancestors,the papermaking skill and three other inventions.Who says the Yellow River Civilization has vanished?Who can ignore the fact that we have established a great country?we have our own Science and Technology,that we have successfully sent Yang Liwhei into space,and that our GNP ranks is the No.7 in the world.Ancient China has undergone lots of dynasties most notably the Tang Dynasty and the Han Dynasty,China has experienced many upheavals,most notably the Three Kingdoms Period.We also have experienced the plundersby other nations But now,China still stand in the world!We are unyielding and unconquerable!
I know an American said,“China has a history of five thousand years,but the US only has a history of 200 years.Five thousand years ago,China took the lead in the world,and now it is the US that is leading.” This remark astounded me.But it is true that we're still a developing nation,but it doesn't mean that we can despise ourselves.We have such a long-standing history,we such have abundant resources,we have such intelligent and diligent people,and we have enough to be proud of.We have reasons to say proudly：we are sure to take the lead in the world in the future again,for our problems are big,but our ambition is even bigger,our challenges、are
great,but our will is even greater.
I am Chinese.I have inherited black hair and black eyes.I have inherited the virtuesof my ancestors.I have also taken over responsibility.I am sure,that wherever I go,whatever I do,I shall never forget that I am Chinese!
I love you China!Thank you for listening carefully!
