I had a wonderful vacation this summer because I filled it with several sporty activities. On the first day, I swam in the lake, and I sunbathed on the beach. On the second day, I went sailing with a friend. On the third day, I went fishing; I caught five lake trout. On the fourth day, I hiked in the woods along a babbling stream. To summarize, I enjoyed my sporty vacation, and I’m looking forward to a similar vacation next year.

I love my school very much. I go to school every day to study. My school is located in the center of the commune. My school has 4 buildings. Each building is 5 stories high. They are arranged in a U shape. My school yard has many trees. There are very large tree trunks. One person can’t hug them all. My school has many classes. In addition, my school also has a library to read books, a canteen for us to buy food during recess. My classroom is on the 3rd floor. I like the hallways of my school. The corridor is wide and there are small potted plants to make the space fresher. My school doesn’t have an elevator. Every time there was a class on the 5th floor we would have to walk up. When I was a student, I was attached to this school. I love it so much. I always try to keep the school and classroom clean. My friends and I spread the word not to litter. Every month we will clean the school together to keep the school clean.
