成为班干 To be a Class Leader

Last week, my teacher told us that she would choose some students to be our class leaders and the students could run for it. I wanted to be a class leader and practice myself. But I was too shy to say a word. After struggling for a few days, I decided to run for the job and I made it. I was so happy. 
上周，我的老师告诉我她想要选一些学生成为班干，学生可以为此进行竞选。我想成为一名班干，并且锻炼自己。但是我讲话太害羞了。经过了一段时间的挣扎以后，我决定竞选班干，我成功了。我很开心。
