阅读理解(10分)
Leaves
are
nature’s
food
factories.
Plants
take
water
from
the
ground
through
their
roots.
They
take
a
kind
of
gas
called
carbon
dioxide
(CO2)
from
the
air.
Plants
use
sunlight
to
turn
water
and
CO2
into
glucose.
Glucose
is
a
kind
of
sugar.
Plants
use
glucose
as
food
for
energy
to
grow.
The
way
plants
turn
water
and
CO2into
glucose
is
called
photosynthesis.
That
means
“putting
together
with
light”.
A
chemical
called
chlorophyll
helps
make
photosynthesis
happen.
Chlorophyll
is
green.
It
gives
plants
their
green
colour.
As
summer
ends
and
autumn
comes,
the
days
get
shorter
and
shorter.
This
is
how
the
trees
“know”
to
begin
getting
ready
for
winter.
During
winter,
there
is
not
enough
light
or
water
for
photosynthesis.
The
trees
will
rest,
and
live
on
the
food
they
have
stored
during
the
summer.
They
begin
to
close
their
food-making
factories.
The
chlorophyll
disappears
from
the
leaves.
Then,
we
begin
to
see
yellow
and
orange
colours.
A
few
of
these
colours
stay
in
the
leaves
all
the
time.
We
just
can’t
see
them
in
summer,
because
they
are
covered
up
by
the
green
chlorophyll.
Red
and
purple
colours
we
see
in
leaves
are
made
mostly
in
autumn.
In
some
trees,
like
maples(枫树),
glucose
is
stored
in
the
leaves
after
photosynthesis
stops.
Sunlight
and
the
cool
nights
of
autumn
turn
this
glucose
into
red.
The
brown
colour
of
trees
like
oaks(橡树)is
made
from
wastes
left
in
the
leaves.
