My good friend is a beautiful girl called Betty, who is 12 years old now. She was born in England but these years she lives in Nanjing. She looks very tall and slim, and she wears long black hair. She studies in the 7th grade at Nanjing No.1 secondary School, in Class 1. She loves reading, and every Friday afternoon is her time for a reading club. What's more, she likes singing.She listens to the music at weekends, too. She is polite and helpful, and everyone likes her very much.你稍做刪改就行了
