Last year，I lived in Chile for half a year as an exchange student with the American Field Service.I lived with a Chilean family and had the responsibilities of 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 the urban middle-class American I was accustomed to.There were lots of dogs on the streets，and there was no downtown，few smoothly paved streets，and little to do for entertainment.Rain was not seen very often.Earthquakes and windstorms were frequent.
   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 barely able to communicate and needed one person to whom I could explain my shock.I couldn't speak the thoughts in my head-and there were so many.
   Most exchange students experience this like me.Culture shock presents itself in everything from increased aggression towards the people to lack of appetite.I was required to overcome all difficulties.
   As time passed，everything changed.I began to forget the words in English and to dream in Spanish and love Chilean food.I got used to not depending on expensive things for fun.Fun in Chuquicamata was being with people.And I took math，physics，chemistry，biology，Spanish，art，and philosophy.
   But the sacrifices（犧牲） were nothing compared to the gain.I learned how to accept and to succeed in another culture.I now have a deeper understanding of both myself and others.
