Hello, my name's Tien. Today, I'm going to tell you about my best friend. Her name is Dan. She is eleven years old. Her address is 116 Le Loi Street. She is tall and strong. She is clever and helpful. She always sloves maths problems and helps me do homework.  She often rides a bike and does her homework at the weekend. She wants to be an English teacher in the future. Thanks for listening. Goodbye! See you soon!
