Today is the first day of my summer vacation. The weather was sunny and warm. I woke up early and had a delicious breakfast. In the morning, I went to the park with my friends. We played basketball and had a lot of fun. In the afternoon, I stayed at home and read some English books. It was a great way to improve my language skills. In the evening, my family and I went to the beach. We enjoyed the beautiful sunset and had a picnic. I had a wonderful day and can't wait for more adventures this summer.
