I've been farming sheep on a hillside for 54 years. I use a small tractor to get about. My dog Don always sits beside me in the passenger scat.
One morning I 1 a lost lamb when I was in the top field，near where a motorway cuts through my land. The lamb had become separated from its 2, so I jumped out of the tractor to 3 it while Don stayed in his scat.
Lamb and mother 4, I turned back to the tractor only to see it move suddenly away from me. This was so 5 because I had put the handbrake on when I jumped out. 6 Don had somehow made the 7move.
My heart froze in my chest as I 8 the tractor heading towards the 9 .I ran desperately but failed to 10. It crashed through a wooden fence and disappeared. The 11 thing I saw was Don's face, looking calmly back at me.
Heart in mouth, I 12 the fence and looked over. The tractor was 13against the crash barrier in the central reservation, having miraculously(奇迹般地) crossed the 14 road with fast-flowing traffic. I couldn't see Don, but as I 15 the tractor he jumped out onto the road, apparently 16, and dashed back to me.
The police 17 and the motorway ran normally again. I couldn't quite believe my 18it turned out no one got badly hurt, but the outcome could have been 19 .Don was given a special 20 that night—I didn't want him thinking I was angry with him.
