Sarah decided to spend her summer vacation learning how to swim. She signed up for swimming lessons at the local pool. Every morning, she would practice her strokes and improve her technique. After a few weeks, Sarah was able to swim the length of the pool without stopping. She was very proud of her progress. On the last day of her lessons, her instructor awarded her a certificate for completing the course. Sarah felt a great sense of accomplishment and was excited to continue swimming in the future.
