Rex is a dog that lives at the bakery next to our school. He is cute and friendly. Every morning, he stands in front of the school to welcome everybody. We all see Rex as one of us. But one Monday morning, I was surprised that Rex was not there to say hello to us. “Rex is in the hospital. He was hit by a car last night,” my classmate told me. We went to see Rex in the hospital that day after school. Two weeks later, Rex was much better, and we decided to take him for a walk every evening. Because of the exercise, Rex became healthier and stronger. Soon he could happily run and jump again. He is now as handsome and strong as before!
