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. (     )1. A. however
