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。
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 dongs family is wealthy， he is usually simply dressed。 he has a dream which is to be a lawyer。
such is my friend， a clever and kind boy。 he is highly praised by the teachers and students。
张东是我最好的朋友。他是上学期来我们班的，他是个男孩。我们两个人都擅长英语，因此我们经常在课余时光用英语聊天。放学后，我们经常在操场上踢足球。他跑得个性快，我追不上他。他是个优秀的学生，他不但各科功课好而且很友善、谦虚。他喜欢流行音乐，也喜欢古典音乐。
他家有三口人，他是独生子。父亲是个医生，母亲是个京剧演员。尽管张东家境比较富裕，但是他的穿着却十分朴素。他有一个梦想，就是将来当个律师。
这就是我的朋友，一个聪明、友好的男孩。老师和同学们都喜欢他。
