Ada looked through the observation window at the kids below, all waiting in line to get into the pool. She turned to her mother with an angry expression on her face. “Mom, they’re all little kids! I’m 15 already! This is ridiculous, isn’t ?”
“I know, Ada,” replied her mother, “but you’re a beginner, too, and you have to start somewhere!”
Ada had never been to a swimming lesson in her life. Between schoolwork and helping on her grandfather’s farm, she hadn’t had time for lessons. The closest swimming pool Ada had been to was the inflatable (充气的) alligator pool her mother bought her when she was five. Now that Ada was older, her mother had found a new job in the city, and Ada faced a new challenge — school field trips to the local pool.
The first day that Ada went with her class to the pool, she had no idea what she was in for. What could be so difficult about swimming? Ada confidently slipped(溜) into the water and held onto the side of the pool, expecting to be able to touch the bottom with her feet. But when Ada let go of the side of the pool, she slipped under the water—the whole pool was one big deep end! Ada threw her arm toward the side of the pool and grabbed (抓住) the ledge (池壁), out of breath. “I really can’t swim! Everyone’s going to laugh at me!” she thought to herself in a panic.
On the next field trip to the pool, Ada sat on the side of a bench, frozen with fear. She huddled (蜷缩) with a towel over her shoulders, too embarrassed to try again. When she came home, her mother noticed right away that Ada was upset. “Honey, I want you to take Bella’s swimming lessons at the local pool. Soon you’ll learn how to swim just like everyone else,” she convinced Ada, showing photos of Bella with her prize-winning students. Ada felt doubtful whether the lessons would help, but she had to overcome her fear.
