完形填空（共20小题，20分）
The sun was shining when I got on No. 151 bus. We passengers sat jammed in heavy clothes. No one  36 . That’s one of the unwritten rules  37 we see the same faces every day, we prefer to  38 behind our newspapers. People who sit so close together are using them to keep  39  distance.
As the bus came near the Mile, a  40 suddenly rang out, “Attention! This is your  41 speaking.” We looked at the back of the driver’s head. “Put your  42 down, all of you.” The papers came down. “Now, turn and  43 the person next to you.”
Surprisingly we all did it. Still no one smiled. I faced an old woman. I saw her  44 every day. We waited for the next  45 from the driver. “Now repeat after me. Good morning, neighbor!”
But our voices were a little  46 . For many of us, this was the  47 word we had spoken that day. When we said them together, like  48  to people beside us, we couldn’t help  49 . There was the feeling of relief. Moreover, there was the sense of ice being  50 . To say the three words was not so  51 after all.
The bus driver said nothing more. He didn’t  52 to. Not a single newspaper went back up. I heard laughter, a  53 sound I had never heard before in this bus.
When I  54 my stop, I said goodbye to my seatmate, and then  55 the bus. That day I was starting happily.
