完形填空。 The sun was shining when I got on No. 151 bus. We passengers sat closely in heavy clothes. No one spoke. That's one of the unwritten rules. Although we see the same faces every day, we prefer to 1 behind our newspapers. People who sit so close together are using those newspapers to keep their distance (距离). As the bus came near the Mile, a voice suddenly rang out, 'Attention! This is your driver 2 .' We 3 the back of the driver's head. 'Put your papers down. All of you.' The 4 came down. 'Now, turn and face the person next to you. Go ahead.' Surprisingly we all did it. Still no one smiled. I faced an older woman. her head wrapped (裹) in a red scarf. I saw her 5 every day. Our eyes met. We waited for the next order from the driver. 'Now repeat after me. Good morning, neightbor!' Our voices were 6 . For many of us, these were the 7 words we had spoken that day. But we said them together, like 8 , to the strangers beside us. We couldn't help smiling. There was the 9 of relief (解脱). Moreover, there was the sense of ice being broken 'Good morning, neighbor.' It was not so 10 after all. Some of us repeated it, others shook hands, and many laughed. The bus driver said nothing more. He didn't 11 to. Not a single newspaper went back up. I heard laughter, a 12 sound I had never heard before in No. 151 bus. When I reached my stop, I said goodbye to my seatmate, and then jumped off the bus. That day I was starting off happily.
