[单选题]Passage 2Last year I lived in Chile for half a year as an exchange student with the American Field Service. Compared to most visitors,I didn't travel much. I lived with a Chilean family and had the responsibilities of any Chilean teenager.I went to school every day, in uniform. I had good days andbad days and days that I didn't understand.Chuquicamata, my host community, is a mining camp in the Atacama Desert. There is no disco, no shopping center, no museum or beach. Driveways must be watered daily to keep the dust down.When I arrived here,I was scared. It was so different from the urban middle-class America I was accustomed to.

Culture shock presents itself in everything from increased aggression toward the people to lack of appetite or weight gain and depression.I was required to overcome all difficulties.

Fun in Chuquicamata was being with people. And I took math, physics, chemistry, biology, Spanish, art, and philosophy.But the sacrifices were nothing compared to the gain.I learned how to accept as well as to succeed in another culture.I now know the world is my community and have a much deeper understanding of both myself and others.On arriving in Chile, the author felt frightened because________.
