Nun kommt mein Text :

Dear Sixteen,
There are a few things about German schools that I would like to change f i Could.
For exampel, I don`t like is the short break.
The ten minute aren`t enough.
Another point that should me mentioned is that the classrooms aren`t the wales beautiful.
The food in the canteen isn`t good.
The summer holiday can be longer.

There are some good things too. For example, that our school have two big gymnase .
Some thing good is that we don`t have dresscode.
The schoolyard is often clean and the bus station is exact at the school.

Danke euch.
Euer Quizman
