Do you want to know about my staying in America? It was really an eye-opening experience. In China, I had English classes five times a week. However, I didn't know how different textbook English was from daily English until I went to Hotchkiss School, Connecticut. When I first studied English, I was told to say "I'm fine" when people say "How are you?" But in America, I found that people said "I'm 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. To my surprise, American girls spend a lot of time in the burning sun. However, in China, girls try every possible way to get their skin whiter. I'm also surprised by how hard-working American students are. In China, schoolwork is almost everything, so we study hard. But in America, a good student gets good grades, does a lot for the public and plays sports or music. Which of the following is NOT true according to the passage?
The writer has returned from America. American girls love to have white skin. Schoolwork is almost everything for Chinese students. American students are hard-working.
