Dear Mrs. Winthrop,

　　So my first week at college is over! No lectures this morning so I think I’d email you and let you know what things are going.

　　I’m glad to say that anything has worked out fine in the dorm. I remember asking for a room as far away from the lifts as possible and they find me a comfortable one second floor. There are two girls from my course here and I plan to make friend with them so we can help each other on the course work. Everyone else seems very nice and warmly here.

　　Well, I had better to stop now. I’m going to attend mine first lesson this afternoon, for I’ve got some preparation to make, Keep in touch.

　　Best,

Carol
