英語詩歌:To Waken an Old Lady

Old age is
    a flight of small
    cheeping birds
    skimming
    bare trees
    above a snow glaze.
    Gaining and failing
    they are buffeted
    by a dark wind --
    But what?
    On harsh weedstalks
    the flock has rested --
    the snow
    is covered with broken
    seed husks
    and the wind tempered
    with a shrill
    piping of plenty.
