Thursday, May 1st

The weather was fine today. I went to the beach for a trip with my classmates. There were many people there on vacation. They were friendly to each other. At first, we swam happily in the sea. Then we played beach volleyball. When we were tired, we lay on the beach and relaxed. At noon, we felt a little hungry, so we went to have some seafood. It was very delicious!

　　All of us had a great time!
