（2020·浙江7月高考）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 seat.

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 seat.

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    7    move.

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    13    against the crash barrier in the central reservation， having miraculously（奇跡般地） 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     18    it 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.
