Tian Hua is a new student at a school in America. She is studying at an American high school for one year. In China, Tian Hua was in Grade 1 at high school, but in America, she is in Grade 10! She did not feel confident at all when she arrived. Her first impression was that English was difficult and people spoke too quickly, but soon she found that if she concentrated on the ideas, not the single words, she could understand! She also made friends and began to explore the city with them. Her new friends were happy to explain things to her after class. Her favourite class is chemistry because the teacher lets the students do cool experiments. Tian Hua is not sure how well she will do at school this year, but she is not nervous any more. She is excited!
