题型:问答题 简答题


I’d been travelling for long hours on a lonely country road when I had a flat tyre. So I had to        and get the tools to fix the problem. It certainly wasn’t        doing this with a white shirt and suit on.
Nightfall was approaching. Suddenly a car pulled up beside me. A man got out and offered to        me. Seeing tattoos (纹身) on his arm, I became        as thoughts of robberies flashed through my mind. But        I could say anything, he had already begun to take the tools to change the        . While watching him, I happened to look back at his car and noticed someone sitting in the passenger seat. This        me.
Then, without warning, it began to rain. He suggested that I wait in his car because my car was unsafe. As the rain increased, I unwillingly agreed. When I settled into the back seat, a woman’s voice came from the front seat. I replied with much        when seeing an old woman there. It must be his mother, I thought. To my surprise, the old woman was a neighbor of the man who was helping me. “Jeff insisted on stopping when he saw you        the tyre.” “I am grateful for his help,” I said. “Me too!” she said with a smile. He helped drive her to see her husband twice a week in a nursing home. She also said that he        at the church and taught disadvantaged students for free.
Finally, Jeff helped me change the tyre. I tried to offer him money and of course he refused it. As we shook hands to say goodbye I apologized for my stupid        at the first sight of him, and this incident warned us that we shouldn’t judge people by the way they       .
