三、阅读理解-阅读选择（共2小题；共18分）
阅读下列短文，根据短文内容，从短文后各题所给的选项中，选择最佳选项。
Hundreds
of
years
ago,
life
was
much
harder
than
it
is
today.
People
didn't
have
modern
machines.
There
was
no
modern
medicine,
either.
Life
today
has
brought
new
problems.
One
of
the
biggest
is
pollution.
Water
pollution
has
made
our
rivers
and
lakes
dirty.
It
kills
our
fish
and
pollutes
our
drinking
water.
Noise
pollution
makes
us
talk
louder
and
become
angry
more
easily.
Air
pollution
is
the
most
serious
kind
of
pollution.
It's
bad
to
all
living
things
in
the
world.
Cars,
planes
and
factories
all
pollute
our
air
every
day.
Sometimes
the
polluted
air
is
so
thick
that
it
is
like
a
quilt
over
a
city.
This
kind
of
quilt
is
called
hate
(雾霾).
Many
countries
are
making
rules
to
fight
pollution.
Factories
must
now
clean
their
water
before
it
is
thrown
away,
and
they
mustn't
blow
dirty
smoke
into
the
air.
We
need
to
do
many
other
things.
We
can
put
waste
things
in
the
dustbin
and
not
throw
them
on
the
ground.
We
can
go
to
work
by
bus
or
with
our
friends
in
the
same
car.
If
there
are
fewer
people
driving,
there
will
be
less
pollution.
Rules
are
not
enough.
Every
person
must
help
to
fight
pollution.
26.
Hundreds
of
years
ago,
life
was
much
harder
than
it
is
today
because
_____.
A.there
were
not
any
modern
machines
B.there
was
no
modern
medicine
C.both
A
and
B
D.there
were
not
many
people
27.
The
most
serious
kind
of
pollution
is
_____.
A.noise
pollution
B.air
pollution
C.water
pollution
D.A,
B
and
C
28.
From
the
passage
we
know
that
_____.
A.a
few
years
ago,
there
was
no
haze
at
all
B.today
people
don't
have
to
talk
to
each
other
in
a
loud
voice
C.we
can
drink
water
from
the
polluted
rivers
and
lakes
D.people
are
making
rules
in
order
to
fight
pollution
The
population
of
the
Earth
is
growing
faster.
It
is
important
that
we
look
after
the
Earth.
We
need
it!
The
Earth
gives
us
a
lot
of
things.
We
also
give
the
Earth
a
lot,
but
some
of
the
things
are
not
good.
In
nature,
when
something
dies,
other
animals
and
plants
get
food
from
it.
Every
animal
or
plant
gives
food
for
other
animals
or
plants.
However,
animals
can't
get
food
from
many
of
the
things
that
we
'give'
the
Earth.
Animals
and
plants
can't
eat
metal,
plastic
and
glass.
These
things
will
stay
in
the
ground
for
many,
many
years.
Some
rubbish
is
very
dangerous
for
plants
and
animals.
In
some
places,
many
animals
live
together.
One
animal
makes
food
for
many
more
animals.
If
we
put
rubbish
and
chemicals
in
the
water,
the
plankton
(浮游生物)
can
die.
If
there
isn't
any
plankton,
many
animals
have
nothing
to
eat.
So
what
can
we
do?
Don't
leave
any
rubbish
in
the
countryside!
Don't
make
so
much
rubbish!
29.
The
Earth
gives
us
_____.
A.food
B.rubbish
C.chemicals
D.pollution
30.
When
something
dies
in
nature,

and
grass
are
polluted
B.plastic
and
wood
become
food
C.other
animals
and
plants
get
food

and
glass
stay
in
the
ground
31.

must
_____
to
look
after
the
Earth.

in
the
ground

more
wood

frogs
in
the
water

less
rubbish
