    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.

材料二：乾隆皇帝在给英王乔治二世的信中说：“天朝物产丰盈，无所不有，原不籍外夷货物以通有无，特因天朝所产茶叶、丝帛为西洋各国及尔国必须之物，是以加思体恤。”
