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 confused(不知所措). 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(晒黑). However, in China, girls try every possible way to get their skin paler, or “whiter”.
I was also surprised by how hard-working 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 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.
【小题1】According to the writer, textbook English is ______ everyday English.

When I was ten, my mother worked all day so I had to take care of my younger brother. At that time my little brother was about four years old and he missed mum all the time.
One day, after I had given him his dinner, he started crying for mum.He was so young and really needed mum. So I dressed him, put on his shoes, carried him on my back and walked out. Soon he fell asleep. About half an hour later, I found that he had lost a shoe while sleeping. I took him off my back and put him down. I knew we needed to find that shoe, for our mother couldn’t afford new shoes. We had to go back to find it, so I told my brother to wait right there. A man heard it and stopped me just before I walked off. He asked me, “You are leaving your brother here to find the shoe? What would you do if he is not here when you return?” I did not know how to answer that question. He continued, “It’s OK if you can’t find the shoe, but it is not OK to lose your brother.” Then he sent us to mum’s workplace by taxi.
My whole life I have depended on the kindness of many strangers, I feel regretful that I cannot find them and say thank you. I do not even remember what the man’s face looked like, but he taught me a lesson—people are more important than things.
