Translation of Dunkelgrün

Grammar exercises give the teachers and the students different ideas. We discussed the need for exercises in my previous email, but unfortunately I did not receive any further feedback since then.
I hope that I will have time to go skiing. Maybe it is even better to go at the end of the season. The doctor, however, did not give his diagnosis yet. If I cannot go I will have to find an alternative.
I like music very much too. I prefer classic music, but rock is also good. When you come to my Berlin we need to out to concerts together and visit a few bars. They are all close to the center.
