Last year,I lived in Chile(智利) for half a year last year. I lived with a Chilean family and had to do the same things as any Chilean teenager. I had good days and bad days I didn't understand.
Chuquicamata, my host community, is a mining camp. When I arrived there,I was scared. It was so different from what I was used to. There were lots of dogs on the streets,and there was no downtown(商业区),few good streets,and little to do for fun. Rain was not seen very often, earthquakes and windstorms happened quite often.
I had studied Spanish for two and a half years and was always one of the best students in my class. But in my first week in Chile,I was not able to communicate and I needed a person to whom I could explain my shock.But I couldn't speak the thoughts in my head and there were so many. Most exchange students experience this like me.And I had to deal with all the difficulties on my own.
However, as time passé, everything changed. I began to forget words in English and started to dream in Spanish and love Chilean food. I got used to not buying expensive things for fun. Fun in Chuquicamata was being with people. I took math, physics, chemistry, biology, Spanish, art, and philosophy in school.
What I lost was nothing compared to what I acquired. I learned how to accept and to succeed in another culture. I now have a deeper understanding of both myself and others.
