单选题下列带点的字解释错误的是( )

单选题There were a thousand reasons not to stop. I was running late for a very important...well, whatever it was that I was running late for that day. Surely the Highway Patrol would be along soon, and it"s their job to help stranded(搁浅的) motorists, isn"t it? Let"s see—that makes 1, 004 reasons not to stop. And here"s 1, 005th: I am the world"s worst auto mechanic. The first time I tried to change my car"s oil myself I did fine—until I forgot to put the new oil in. The boys down at the garage had a big laugh over that. I was not sure how much it would have helped that lady who was stranded by the side of the freeway if I had pulled over and given her a hand. So I drove on, just like hundreds of other drivers on the freeway that day. But I felt guilty about it. So I turned off at the next exit and made my way back to see if I could at least give her a lift or something. But by the time I got back to her, a Hispanic(西班牙的) gentleman had pulled in behind her, and was tinkering(修补) her car"s engine. "Is there anything I can do to help?" I asked. "No! Thank you," the lady replied, "this nice man says he can fix it." At that moment, a voice from under the hood shouted, "OK, try it now!" The woman reached for the key and turned it. The engine started beautifully. The woman tried to give him some money, but he declined and waved as she drove off. It wasn"t until we started walking toward our cars that I noticed he had five more reasons not to stop than I did: his family was sitting in the station wagon, waiting patiently. "Do you stop and help people like this often?" I asked. He shrugged. "Somebody has to," he said, "what"s she going to do if nobody helps?" And for him, that reason was enough.
