I was on the 3 after I had made some inquiries (询问). At a shvelle, 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 4 several hills and was dangerous ,I hesitated for a little while and then chose the main road, for I wanted to be 5 . Something strange happened after I drove a long 6 and found it was not the correct road that I wanted to 7 , but the hilly road I decided to avoid .I realized that it was at the 8 that I had made the 9 mistake.
