     You want to know about my staying in America, right? Well, to tell you the truth, it is really an

eye-opening experience study here.

      In China, I had English classes five times a week since fifth grade. However, I didn't know how

different textbook English could be from everyday English until I came to Hotchkiss School, Conmecticut.

     When I first studied English, I was told to say,"I am fine." when people say "How are you?" But in

the US, I found that people say, "I am good." or "I'm tired."

     One day, someone greeted me with "What's up?" It made me confused. I thought for a moment and

then smiled because I didn't know what to say.

     Since then, I have discovered more and more differences between Chinese and US cultures.

     To my surprise, US girls spend a lot of time in the burning sun to get a tan. However, in China, girls

try every possible way to get their skin paler, or "whiter."

      I also surprised by how hard-working.US students are. In China, schoolwork is almost everything,

so we study hard and that' it. But here, a "good" student gets good grades, does a lot for the public and

plays sports or music.

     The kids here are so talented, I am starting to be sorry that I gave up playing the piano at an early

age and that I have never thought about sports.
