AFor 30 years, Randy J. Murphy drove without being stopped by the police—and without a driver’s license (驾驶执照).The 46-year-old man’s luck came to an end last May. On his way home from his job as a dishwasher, he turned up the radio in the car.“I just turned the corner, and there was Mark,” Murphy said of the police officer who has since made such a difference in his life.Officer Mark Taylor had stopped the car as he heard the blaring (震耳的) music. When he asked for a driver’s license, Murphy said that he didn’t have one.Murphy told Taylor he couldn’t read well enough to tale the written part of the licensing test. “He said people just don’t help anymore. I told him if he was willing, I’d help him,” said Taylor. He gave Murphy his phone number. That afternoon Murphy called the officer.For the next three months, the men met several times a week to review the questions which might appear in the test. When Murphy took the test, Taylor went with him. Murphy passed on his sixth attempt (尝试). He then sailed through the road test. On September 5, he got his license.Taylor’s act of kindness won him the Officer of the Month award(奖) from the Knoxville Police Department. “People should help each other if they can,” Taylor said. “Randy did all the work. I just guided him along.”Although Murphy has overcome the difficulty that kept him from getting a driver’s license, he hasn’t stopped there. “We still meet once a week to read,” Taylor said. “We’ve also become friends.”
