完型填空（共15小题，每小题1分，满分15分） School was over and I felt quite tired. I sat at the very 1 of the crowded bus because of my anxiety to get home. Sitting there makes me 2 out like a shiny coin in a pile of dull pennies. Janie, the driver , tries to break the uncomfortable atmosphere by striking the match of conversation . I tried to mind my manners and 3 listen, but usually I am too busy thinking about my day. On this day, 4 , her conversation was worth listening to. “My father’s sick,” she said to no one in 5 ,I could see the anxiety and fear in her eyes. “What’s wrong with him?” I asked. With her eyes wet and her voice tight from 6 the tears, she answered, “Heart trouble.” Her eyes 7 as she continued. “I have already lost my mum, so I don’t think I can stand losing him.” I was 8 . My heart ached for her. And this reminded me of the great 9 that my own mother was thrown into when her father died. I saw how hard it was, and still is, for her. I wouldn’t like anyone to 10 that.

I realized I had only thought of people as 12 as what their purposes were in my life. I paid no attention to Janie 13 she was a bus driver. I had 14 her by her job and brushed her off as unimportant. For all I know, I’m just another person in someone else’s world, and may not even be 15 . I should not have been so selfish and self-centered. Everyone has places to go, people to see and appointment to keep. Understanding people is an art.
