这是我的自我介绍,看看有没有语病,thanks……帮忙改一下吧
Hello,every one.I am a student in Wen Hai Middle School.My name is VV,and you also call me Mandy.I am not a clever girl,so I can’t speak English very well.At school,my favorite subject is Math.Many people thank it’s too difficult,bat I don’t thank so,I think it’s so easy and interesting.
I like dolphins very much,because they are very clever.And I like bees too,because they are very selfless.So I’d want to be a Candidate,I’d like to present a copy of my power to all purpose.
The Olympic Games it’s held in Beijing,it’s Chinese’s dream,on August 8th in 2008,it was achieved at last.
“One world,One dream.” We hold and close congenital dream,it sails to the Olympic Games.
