word can only be used once.

A. accurate
F. enormously
K. prediction

Beyond
two
or
three
days,
the
world’s
best
weather
forecasts

are
based
on
guesswork, and beyond six or seven they are worthless.

The Butterfly Effect is the reason. For small pieces of weather
—
and to a global
forecaster,
small
can
mean
thunderstorms
and
snowstorms
—

any
___41___
fails
rapidly.
Errors
and
uncertainties
___42___,
gathering
upward
through
a
chain
of
unstable
features,
from
dust
devils
(
尘旋风
)
and
windstorms
up
to
continent-size
eddies
(
旋风
) ___43___ satellites can see.
The modern weather models work with a network of points of the order of sixty
miles apart, and even so, some ___44___ data has to be guessed, since ground stations
and
satellites
cannot
see
everywhere.
But
suppose
the
earth
could
be
covered
with
sensors spaced one foot apart, rising at one-foot ___45___ all the way to the top of the
atmosphere. Suppose every sensor gives perfectly ___46___ readings of temperature,
pressure, dampness, and any other quantity a
meteorologist
(
气象工作者
) would want.
Exactly at
noon a(n) ___47___ powerful
computer takes
all the data
and ___48___
what will happen at
each point at 12.01, then 12.02, then 12.03 …

The computer will still be unable to predict whether Princeton, New Jersey, will
have sun or rain on a day one month away. At noon the spaces between the sensors
will ___49___ alterations that the computer will not know about, tiny variations from
the ___50___. By 12.01, those alterations will already have created small errors one
foot away. Soon the errors will have multiplied to the ten-foot scale, and so on up to
the size of the globe.

Rain forests, found in Earth’s temperate and
tropical
(
热带的
) zones, are some
of the most biologically varied ecosystems on the planet. All rain forests share certain
___41___ features, including a closed canopy, thedensevegetation of thetop branches
that
forms
a
roof
above
the
forest
floor,
a
damp
and
warm
climate,
and
___42___
constant temperatures throughout the year. Most of the forest’s insect and animal life
grows wel
l in the canopy’s leafy and sunlit environment. The forest’s groundcover, by
comparison, is small. Less than 2 percent of the sun’s light makes its way through the
canopy and the darkness below. This darkness, along with the poor quality of the soils,
___43___ plant growth.

Rain forests are a(n) ___44___ part of Earth’s total ecology. Huge amounts of
water
are
absorbed
into
tree
roots
and
___45___
into
the
atmosphere
from
the
tree
leaves
through
a
process
called
transpiration

(
蒸发
).
Tree
roots
also
fix
the
soil
in
place
and
slow
the
runoff
of
rains
into
rivers
and
oceans.
Through
the
process
of
photosynthesis
(
光合作用
), rain forests absorb more carbon dioxide and give off more
oxygen than any other ecosystem.

The
rain
forests
are
___46___
shrinking
at
a
rapid
rate
as
a
result
of
the
profitable
ventures
of
farming,
logging,
and
mining.
When
tropical
rain
forests
are
___47___
in
order
to
raise
cattle
and
crops,
the
nutrient-poor
soils
are
quickly
