His name is James,but people call him Rocky.The name fits.He’s big,over six feet tall,and he’s tough when he needs to  be.James “Rocky” Robinson lives and works in New York City’s Bedford­Stuyvesant district,one of the poorest and most dangerous neighborhoods in the United States.Yet it is here in Bed­Stuy that he is saving lives and reviving a community.

In 1966,when Rocky was twenty­six years old,his seven­year­old niece was struck by a car on the street of Bed­Stuy.Had someone at the scene known first aid or CPR,she might have lived.But by the time she reached a hospital,she was dead.

His niece’s unnecessary death was one reason why Rocky became a paramedic (护理人员).Working for the Emergency Medical Service of New York City,he realized that more than half the city’s emergency calls came from high­crime areas.According to Rocky,residents of crime­plagued minority neighborhoods like Bed­Stuy sometimes had to wait as long as 26 minutes after calling 911 for an ambulance while calls in richer white communities were answered in_a_fraction_of_the_time.

Rocky decided to find out more about the problem.His research showed that the richer communities had organized their own ambulance corps (特殊部队) to improve city services because the city was overwhelmed with calls.“If that’s the key to success,”he told his friend and EMT (Emergency Medical Technician) colleague,Joe Perez,“we’ll start our own corps in Bed­Stuy!”

In 1988,Rocky had no idea that he and Joe would be attempting to establish the first minority­run ambulance service in the country,or just how creative he would have to be to overcome the difficulty.The pair’s first challenge was to find a location for the headquarters.They took over an abandoned building that was commonly used by drug dealers.Because there was no electricity or running water (except for the leaks in the roof),the two men worked during daylight hours.They used a two­way radio to receive emergency calls.

Although they could make do with their new headquarters,Rocky and Joe still lacked the most important component of an ambulance service:an ambulance.An old Chevrolet (雪佛兰) got them to the scenes of accidents,fires,shootings,and stabbings.But the car didn’t always start.At times,they were forced to strap (用带捆绑) their trauma kits and oxygen tanks to their backs and run on foot to the emergencies.Everyone laughed,except the victims who were still alive when  Rocky and Joe arrived.
