Ron never planned on being a teacher. After 2 , he travelled around the world, living a life 3 of adventures(冒险), but after getting terribly sick, he went back to his hometown, North Carolina. Then he got 4 again and taught at a school there. “From then on it was like magic — I fell in love with teaching.” said Ron. After five years of teaching, he heard that some schools in East Harlem, New York were failing because there were 6 good teachers. “At that moment I had a(n) 6— it was like a calling,” he said. “And so I said, ‘I’m going to do it.”
