答案来了！读书论坛上就是高手多。
(From http://www.mreclipse.com/Special/LEprimer.html)
During a total lunar eclipse, the Earth blocks all direct sunlight fro
m the
Moon. Astronauts on the Moon would then see the Earth eclipsing the Su
n. (They
would see a bright red ring around the Earth as they watched all the s
unrises
and sunsets happening simultaneousely around the world!) While the Moo
n remains
completely within Earth's umbral shadow, indirect sunlight still manag
es to
reach and illuminate it. However, this sunlight must first pass deep t
hrough
the Earth's atmosphere which filters out most of the blue colored ligh
t. The
remaining light is a deep red or orange in color and is much dimmer th
an pure
white sunlight. Earth's atmosphere also bends or refracts some of this
light so
that a small fraction of it can reach and illuminate the Moon.
