You want to know about my staying in America, right? Well, to tell you the truth,it is really an eye-opening experience to 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, Connecticut. 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  _ . 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 was also surprised by how hardworking US students are . In China, schoolwork is almost everything, so we study hard and that's it. But here, a "good" student gets good grades, does a lot of work 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. Which of the following is NOT true ?
The writer is now in US. American girls love to have white skin. US students are talented and hard working. The writer regrets  that he gave up playing the piano.
