I made up my mind to drive to South Carolina to meet my friends in my used car. Though I had only been there once  36  and did not know the  37  very well, I was on the  38  after I had made some inquiries (询问).
At Ashvelle, there was a crossroad where I could go on along the main road or I could take a short cut. The short cut was to  39  several hills and was dangerous, I hesitated (犹豫)for a little while and then chose the main road, for I wanted to be  40 .
Something strange happened after I drove a long  41  and found it was not the correct road that I wanted to  42 , but the hilly road I decided to avoid. I realized that it was at the  43  that I had made the  44  mistake. “What shall I do?” I asked myself. If I went back to take that road again, it would be very late by the time I got to Columbia. Thinking it  45 , I decided to go on. “If  46  people can go along this road, why can’t I?” I  47  myself
The short cut, to my surprise ,was not that  48 . In fact, it was only a very peaceful country road,  49  up and down two low  50 .There was  51  traffic. On both sides of the road, you could see trees, wild flowers, and  52  with cows and horses. My fear was  53  with the wind. Listening to the beautiful country music over my car stereo (立体声), I drove on and  54  the scenery which was so quiet and so natural. Even my used car forgot to give me  55 . It was just in this light heartedness that I arrived at my destination. My friends, after they heard what had happened to me, all said it sounded like an adventure.
