     Every year millions of people travel by plane without difficulty. I don't   1   very often, but I always seem
to   2   into trouble. Trouble seems to like me; it goes with me   3   a friendly dog! Last year, for example, I
wanted to come home   4   a winter vacation in Miami, Florida. I had to   5   a plane to Atlanta and then take
another plane home. We left Miami on a Sunday morning. The   6   there was warm and sunny. We arrived
in Atlanta at 12:30 p.m. but then it   7   to snow. In the next three hours,ten inches of snow fell.   8   the plane
could not leave. After twenty-four hours at the Atlanta airport, I was able to   9   my journey! I arrived home
and went to  10  .
     "You look tired," the people at work said. "You need a vacation!" 
     This year I had to go to Washington D.C. for an important business meeting.  11  the plane journey, I
wore sports clothes; they were old, but I felt  12  in them. My good clothes for the meeting were in my
suitcase (手提箱). That was a very  13  idea! I  14  in Washington, but my suitcase didn't. Maybe it went
to London or  15  to San Francisco, I didn't know, but it didn't arrive in Washington  16  me! I went to my
important meeting  17  my tennis clothes. Now that is not a good way to  18  business! People in Washington
wear suits to business meetings, not shorts and tennis shoes. My meeting did not  19  well. That was two
weeks ago. Now I am home again, and I am  20  waiting for my suitcase.
