Question

完形填空。
I am a people watcher, a trait magnified when I travel. On the train to and from Tokyo, I realized,   1   , that my fellow riders who were Japanese rarely   2     up and around or used their eyes to interact with other people. This   3  me at first. To my American mind such interaction has the   4    of mutual (相互的) acknowledgement. But  then  I remembered    5   that the Japanese rarely maintain direct eye contact. Perhaps my people watching seemed  6     . I tried to be more subtle (细心的).       I had also read how the Japanese feel     7     to each other as a group by a sense of responsibility.    8     , as a Caucasian Westerner, I was obviously an outsider, I often     9     being a temporary member of the group. Once, sitting at a long stop of a local train, I 10  as several people got up and left the car when a faster train to their  11   pulled into the station. It was cold outside and every person   12  to press the "CLOSE" button as they exited the train doors to help keep out the cold air for the group  13onboard.     I always feel a bit embarrassed at having the unearned good fortune of being a  14   speaker of the language. In Japan I was  15  for the many kind strangers who were willing to use their English to  16   me. And in a country where the Roman alphabet is not used in the local language, the abundant English signage was  17  aimed at helping travelers.      For the most part on this trip, I found that I was left alone until I asked for help.I   18  little curiosity or interest in interacting with me.   When I entered a restaurant or shop, I felt I was   19 as a local resident would be. Welcome is the greeting often shouted out   20  by the staff when customers enter restaurants or stores.
