作文：I am a girl born in a small city. The year I was 18, I left my hometown and came to a big city where I am going to study and spent my five-year campus life there. I have learnt to do everything by myself and enjoy good relationship with classmates in the college, which I used to be so much worried about. Be more confident and independent, I really look forward to enjoying a campus life in America. There’s no doubt that I’ll learn much more from the friendly people and culture there where is neither in my hometown nor my country.
I major in Urban Planning in my university, which is a dream for me when I was young. I try my best to learn more about it, and do pretty well in architecture. In addition, I really go for in art designing and painting. The interests and hard-working help me get the first price in a designing competition. When I learnt that my dreaming subject, Landscape Architecture is just available in UC Davis, I was so happy.
Urban Planning is a subject requires various knowledge, science and art, internal and external. And if I get the chance to go abroad means I get the chance to know more. It’s certain that the rich experience will help a girl get closer to her goal, which is to be a qualified expert in Urban Planning. In the near future, I plan to put my knowledge into practice. Teachers and Books teach me what other countries do with city development, but I never really know what it is like. So during the time I study abroad, I want to complete a cognitive map of UC Davis, have a study of image space on small scale.
