写一篇英语作文，详情看问题补充，急啊，中午就要。。

Dear Miss Wang,
I'm Kathy. I used to be short and shy when I was in Grade Seven. Now I am taller and outgoing. I was weak in English in Grade Seven , but now I am good at English because I have good ways of learning English and I study harder and harder. I often get up early and memorize the words and the articles for more than ten minutes in the morning. I aiso study grammar and take grammar notes every day. I like listening to English programs and watch English movies. When I have problems in English, I often ask my teacher and classmates for help. I try as hard as possilbe in English learning so I can get good grades now.
yours
Kathy
