My next vacation will be wonderfully for me. I will go to Maryland to visit my friends. I have known her for eleven years since I am in high school. Right now, she is studying English at the University of Maryland. When I visit her, she will have to go to her classes, but we will have lots of free time together either. When we went high school together, she didn’t study very much hard. She wasn’t getting very good grades. And now she is a very good student in American. She know that she should study hard to success. We will have a great time together this summer.
