I was driving an eyesore（丑陋的东西）that could only be 36 as a “ car ” by someone who was either a shameless liar or a good friend . It was 37 to drive the car because you had to keep your fingers and toes crossed to keep the engine running . I tried to imagine I was driving a huge clumsy 38 ; that way I didn’t 39 the slow speed . That night I must have uncrossed my fingers to scratch something . The car 40 in the middle of a four-lane stretch of Oak Street . I 41 for a place to turn off（拐弯）, but the street was lined with parked cars . There I sat , in 42 traffic , as tons of vehicles screamed by . In my rearview mirror（后视镜）I saw a car 43 behind me . I knew what was coming . Soon the horn would start and someone would be 44 at me . But I was 45 . A stranger got out of the car and came to my 46 .
