1、

Zhang Dong is my best friend. He entered our class last semester. He is a boy. Both of us are good at English， so we often have a chat in English in our spare time. After school， we often play football together on the playground. He runs so fast that I can not catch up with him. He is an excellent student. He not only gets good marks in all subjects but also is very kind and modest. He loves popular songs and also classical music.

2、　　There are three people in his family and he is the only child. His father is a doctor and his mother is a Beijing Opera actress. Though Zhang Dong's family is wealthy， he is usually simply dressed. He has a dream which is to be a lawyer.

3、　　Such is my friend， a clever and kind boy. He is highly praised by the teachers and students.
