     A woman I know stood on the bathroom scales (浴室磅秤) after two weeks of diet and hard exercise
around the park. The needle was   1  , stuck on the number where she had started. This struck her as   2   
of how things had been going lately. She was destined (注定) never to be happy.
     As she dressed, feeling her tight jeans, she   3   a ten-pound note in her pocket. Then her sister phoned
with a   4   story. When she hurried out to the car-annoyed that she had to get petrol-she discovered her flat
mate had already   5   the tank for her. And this was a woman who thought she'd   6   be happy.
     Every day, it seems, we're   7   with advice about happiness. The cruel message is that there's something
we' re supposed to do to be   8   (make the right choices, or have the right set of beliefs about ourselves.)
     Coupled with this is the   9   that happiness is a permanent condition. If we are not joyful all the time, we
  10   there's a problem.
     Yet what most people  11  is not a permanent state of happiness. It is something more ordinary, a  12  of
what the American writer Hugh Prather once called "unsettled problem, ambiguous  13  and vague (不明确的)
defeats with few moments of clear peace."
     Maybe you wouldn't say yesterday was a happy day,  14 , you had a quarrel with your boss. But weren't
there moments of happiness, moments of  15 ? Now that you think about it.  16 , there a letter from an old
friend, or a stranger who asked where you got such a good haircut? You remember having a bad day, yet
those good moments  17 .
     So in my opinion, happiness is an  18 , not a condition. It's spending a pleasant hour organizing your closet.
It is your family assembled at dinner. It's in the present not in the  19  promise of a "someday when…". How
luckier we are and how much more happiness we experience-if we can fall in love with the life we are  20 .
