读后续写原文：
“Ada! Milk!”Mama called.
Milk. It was Ada's turn to get it. Ada sighed and shut her first-aid book. Her head hurt from reading in the dim morning light, but how else was she going to learn?
Ada tied the cow close to a tree. Somewhere down the mountain, some volunteer doctors were teaching medical skills to village nurses. Ada heard Betty drive off hours ago. “She should have taken me with her. She thinks I'm too young, but she's wrong. I am already 16!” Ada thought.
Ada carried the milk back to Mama, then wandered up the road. Roy, a village boy, had gotten a donkey, and some kids had gathered around to see it. Roy was always doing something to get attention. Like now: he was trying to stand on the animal's bare back.
“No wonder they don't trust kids with anything important,” Ada thought, sighing. She had just turned away when she heard a thud and a few screams. Roy lay on the ground nearby moaning in pain. The donkey stood several meters away. “Roy!” The kids nearby ran towards him.“Get Betty,” one said. Ada shook her head. “Betty's gone to the city.” The other kids seemed frozen in place.
Ada ran to where Roy was lying. She dropped to her knees on the dusty road. “Roy! Can you hear me?” Roy moaned in agony. Ada saw that one of his leg was crooked, bent a little sideways between the knee and the ankle. A broken leg!
She remembered what the first-aid book had said about broken legs: if there is no ambulance, straighten the bone before moving the victim. There certainly wouldn't be any ambulance here. Ada looked back up the road. The other kids were still standing there, watching. “Victor!” Ada called to one of the boys. “Go get Roy's mama, and find someone with a truck.” She turned to the others. “Give me your shirts. We need something to tie his leg with.”
