看这篇英语自我介绍：
Good morning,teachers and friends:my name is Alen.I'm glad to meet you here.I'm 13 and I'm a humor middle school student.I like many things,such as badmintin,table tennis,violin,books and so on.My best food is the candy,because it can make you drown into its sweetness.And my favourite colour is blue and white because they can give you a feeling of freshment.I have two different characters,sometimes active,while sometimes shy.So this is me,a humor girl!
这里面肯定有错误,而且不止一两处,什么单词、语法方面都有错误,请英语高手们帮我把它修改成一篇完全正确的自我介绍啊!（注意：不要改变文意）
