    I once had a teacher whose husband died suddenly of heart attack. About a week after
his death, she   1   some of her thoughts with a classroom of students. As the late
afternoon sunlight shone   2   the classroom windows, and when the class was nearly over,
she   3   a few things aside on the edge of her desk and sat down.
    With a   4   look on her face, she paused and said, "  5   class in over, I'd like to
share with all of you a deep   6   which I feel is very important. Each of us is put here
on   7   to learn, share, love, appreciate and give of ourselves.   8   of us knows when
this fantastic experience will   9  . It can be taken away at any moment. Perhaps this is
the God's  10  of telling us that we must make the  11  of every single day."
    Her eyes were beginning to  12 , but she went on, "So I would like you all to make me
 13 : From now on, on your way to school, or on your way home, find something beautiful

bread floating out of someone's house, or it could be the sound of the soft  16  rustling
(使发出沙沙声) the leaves in the trees…Please look for these things, and  17  them, for
at anytime they can all be taken away…"
    The class was completely  18 . We all picked up our books and went out of the room
silently. That  19 , I observed many more beautiful things on my way home from school than
usual.
    Remember: Life is not  20  by the number of breaths we take, but by the moments that
take our breath away.
