My job
I open the doors of the teaching building in the morning everyday every morning. I sleep in the entrance guard room in the entrance of the dormitory. I blow the whistle at thirty past six (or: six-thirty) (six-thirty sounds more natural to me). Students run at seven o'clock, eat breakfast at thirty past seven (more natural: seven-thirty). They read books aloud. Classes are beginning begin at eight. I will be ready for my class. We eat lunch at twelve.
Comments: How do you get ready for your class? Is this at a university or a high school?
