My school is so beautiful. It is in a small village in Germany. There's a special activity in my school. And I'm sure you've never heard about it. It is called Abi-Ulk. It's the favourite day for us.
Every summer in our school, we have the Abi-Ulk day. On that day, students will no longer take lessons in classrooms but rush onto the playground. They can play games together and have fun for a whole school day. How about the teachers? They have to sit in an obstructed(堵住的) area to ensure that they can't control the students on the other side of the playground.
Last year's Abi-Ulk impressed me a lot. I still remember that it was a hot day. We all went to the playground. But this time, we didn't just play games but had a water fight！Everyone had a water gun. We ran after each other and tried to shoot others with water. The fight was so exciting！After an hour, we all got wet. Then, the school band started to play. Teachers came from their "obstructed area" and joined us. We danced and sang. What a fun day!
