50.According to the
passage, human beings are used to living in the
day light.
If humans
were truly at home under the light of the moon and stars, we
would go in darkness happily, the midnight world as visible to us
as it is to the vast number of nocturnal
The benefits of this kind of engineering come
with consequences -- called light pollution -- whose effects
scientists are only now beginning to study. Light polution is
largely the result of bad lighting design, which allows artificial
light to shine outward and upward into the sky. I`ll designed
lighting washes out the darkness of night and completely changes
the light levels-- and light rhythms -- to which many forms of
life, including ourselves, have adapted. Wherever human light
spills into the natural world, some aspect of life is
affected.
In most cities the sky looks as though it has
been emptied of stars, leaving behind a vacant茫然的 haze霾 that
mirrors our fear of the dark. We`ve grown so used to this orange
haze that the original gloty of an unlit night-- dark enough for
the planet Venus to throw shadows on Earth -- is wholly beyond our
experience, beyond memory almost.
We`ve lit up the night as if it were an
unoccupied country, when nothing could be further from truth. Among
mammals alone, the number of nocturnal species is astonishing.
Light is a powerful biological force, and on many species it acts
as a magnet磁铁. The effect is so p[owerful that scientists speak of
songbirds and seabirds being "captured俘获" by searchlights on land
or by the light from gas flares [fleə]烈焰火光
on marine oil platforms. Migrating at night, birds tend to
collide
Frogs青蛙 living near brightly lit highways suffer
nocturnal light levels that are as much as a million times brighter
than normal, throwing nearly every aspect of their behavior out of
joint, including their nighttime breeding
choruses
Living in a glare of our own making, we have cut
ourselves off from our evolutionary and cultural heritage历史传承 --
the light of the stars and the rhythms of day and night. In a very
real sense, light pollution causes us to lose sight of our true
place in the universe, to forget the scale of our being, which is
best measured against the dimensions
51.What does
"it "(Paragrapg 1) most probably refer to?
The
night.
52.The writer
mentions birds and frogs to show how light pollution affects
animals.
53.It is
implied in the last paragraph that human beings should reflect
on反省 their position in the universe.
54.What might
be the best title for the passage?
The
Disappearing Night
