One hot summer afternoon, I was 42 down the highway to New York when another car suddenly 43 into my lane(車道). My car was in the far right lane,so it ran onto the roadside. As a(n) 44 driver,I moved my car quickly and skillfully back onto the highway without causing any accident.
I was 45 with that driver,but I thought that he just did not pay attention to(注意) the lane change, and he 46 did not do that on purpose(故意).The car ran away 47 after cutting me off. Very soon it disappeared from sight. After a while,I came around a curve(彎道) and found the 48 car. The driver was walking along the roadside. He was an elderly man and looked 49 . As there was no telephone nearby and the nearest services were twenty miles away, I decided to 50 and see what the problem was.
