IV.阅读理解
A
Due
to
climate
changes，Arctic
ice
is
breaking
up
earlier
in
the
spring，and
its
area
is
decreasing.This
is
creating
problems
for
polar
bears
that
make
their
homes
off
northern
Alaska
and
in
Hudson
Bay.
Polar
bears
off
Alaska
normally
hunt
and
raise
their
young
on
ice
sheets
that
float
on
the
ocean.But
as
the
ice
has
melted，the
polar
bears
have
been
forced
to
spend
more
time
on
land.There，they
have
begun
to
frequent(常去)
beaches，feeding
on
the
remains
of
whales
caught
by
native
hunters.For
polar
bears，this
food
is
less
nutritious
than
seals
that
they
normally
catch
on
ice
sheets.The
shrinking(减少)
ice
has
also
forced
more
polar
bears
into
the
ocean.In
the
past，they
only
had
to
swim
short
distances
between
ice
sheets.But
as
the
ice
has
shrunk，polar
bears
have
been
forced
to
swim
longer
and
longer
distances
in
the
open
ocean.This
poses
a
severe
danger
during
rough
weather，and
an
increasing
number
of
drowned
polar
bears
have
been
observed.
In
Hudson
Bay，the
ice
breaks
up
three
weeks
earlier
in
the
spring
now
than
it
did
20
years
ago.Polar
bears
on
Hudson
Bay
fast(绝食)
during
the
summer，waiting
for
ice
to
form
in
the
fall
to
hunt.Every
year，the
summer
gets
longer，and
the
bears
get
skinnier.Over
the
past
25
years，the
average
weight
of
the
female
bears
has
dropped
68
kg.This
loss
affects
their
ability
to
reproduce，and
already
the
number
of
births
has
dropped
by
15
percent.Unless
the
bears
can
learn
to
survive
these
climate
changes，these
giants
of
the
ice
may
one
day
disappear.
1．What
is
Arctic
ice
doing
earlier
each
year?
A．It’s
freezing.
B．It’s
hardening.
C．It’s
melting.
D．It’s
expanding.

is
TRUE
of
polar
bears
that
are
spending
more
time
on
land
in
Alaska?
A．Their
young
are
dying.
B．Their
diet
is
changing.
C．Their
health
is
improving.
D．Their
families
are
growing.
3．What
does
the
writer
imply
about
female
polar
bears
in
Hudson
Bay?
A．They
are
having
fewer
young
now.
B．They
suffer
from
various
sicknesses.
C．They
don’t
need
stronger
protection.
D．They
can’t
find
enough
good
males.
4．In
which

would
you
most
likely
find
this
passage?
A．Medical
News.
B．Society
Today.
C．Wildlife
Journal.
D．Design

【语篇解读】本文讲述了气候变化对于北极熊的生存及繁殖带来的不利影响。
1．答案C
解析：细节理解题。根据第一段第一句中的“Arctic
ice
is
breaking
up
earlier
in
the
spring”可知，北极冰川每年春天较早时候就开始融化。
2．答案B
解析：细节理解题。根据第二段可以看出北极熊正常情况下吃在冰面上可以捕捉到的海豹，但现在由于冰的减少，它们只能以当地猎人捕捉的鲸的残余物为食了。
3．答案A
解析：细节理解题。从最后一段第四和第五两句可知，北极熊的出生率已经下降了15%。
4．答案C
解析：文章出处题。通读全篇可以发现文章叙述的是全球气候的变化给北极熊带来的负面影响，而北极熊属于野生动物，所以推断这篇文章最有可能摘自《野生动物杂志》。

The
world
celebrates
Earth
Day
every
year
on
April
22.But
one
school
in
Potomac，Maryland
tries
to
honor
Earth
Day
every
day.Very
young
children
are
learning
about
the
environment
and
taking
action
to
show
their
love
for
the
Earth.
A
child’s
world
is
the
world
of
playing.They
love
being
outside
in
the
open
air，running，sliding
and
swinging
on
playground
equipment.But
children
at
St.James
Children’s
School
also
add
to
that
fun
by
picking
up
rubbish
in
the
school.Inside，they
learn
to
save
water
and
electricity.They
also
recycle
and
reuse
things.And
every
spring
they
get
the
soil
ready
to
plant
flowers
and
vegetables
in
the
school
garden.
The
children
at
St.James
range
from
six
weeks
to
six
years
old.The
environmental
study
begins
at
age
two.Rebecca
Boker
teaches
the
children
the
importance
of
taking
care
of
the
Earth.Boker
says
every
day
at
St.James
is
Earth
Day.She
points
to
books
in
all
the
classrooms
and
in
the
library.Most
contain
materials
that
urge
children
to
do
something
to
help
the
environment
and
protect
the
Earth.
St.James
children
observe
the
growth
of
plants
from
seeds
to
sprouts(苗，芽)
in
cups
kept
in
the
classroom.Then
they
watch
the
plants
continue
to
grow
after
placing
them
in
the
garden.The
students
also
observe
the
lifecycle
of
some
insects.After
that，they
know
it
is
their
job
to
respect
their
home
just
like
they
want
others
to
respect
theirs.
But
do
these
very
young
children
really
get
the
message
that
their
teachers
try
to
communicate？Ms
Boker
says
yes.On
April
22
the
kids
at
St.James
will
go
out
to
the
school’s
garden
for
the
yearly
clean?up.But
for
them，Earth
Day
will
continue
for
the
school
days
ahead
as
well.

compositions
C．enrich
the
children’s
knowledge
in

V.完形填空
Conservationists
are
breeding(饲养)
lions
in
the
Southern
African
nation
of
Zimbabwe.The
wildlife
experts
hope
to
increase
the
lion
population
to
keep
the
great
cats
from
1
.
In
some
areas，lions
and
human
beings
are
2
control
of
land.Researchers
believe
something
must
be
done
quickly
to
3
the
animals.
The
African
Lion
and
Environmental
Research
Trust(ALERT)
has
more
than
100
4
in
its
breeding
program.Antelope
Park
Farm
is
one
of
two
sites
ALERT
operates
in
Zimbabwe.
Gary
Jones
heads
the
Antelope
Park
Farm.He
says
ALERT
has
become
involved
5
a
sharp
drop
in
the
number
of
lions.His
group
believes
this
has
been
6
mainly
by
humans.There
are
more
people
moving
to
this
area
every
year.The
lions
have
7
land
on
which
to
live.
Gary
Jones
says
the
decrease
in
the
lion
population
affects
the
whole
8
.He
adds
that
other
African
nations
are
also
seeing
the
9
effects
of
this.
There
are
countries，
10
in
central
and
north
Africa，where
the
lion
population
has
reached
a(n)
11
level.Burundi，a
country
of
east?central
Africa，for
instance，does
not
have
lions
in
its
national
parks.
It
12
wants
to
have
lions
reintroduced
back
into
its
national
parks.The
reason
is
that
when
you
take
the
lion
out
of
the
equation(平衡)，suddenly
you
get
all
13
things
start
happening
with
the
balance
of
14
.For
example，you
get
too
many
prey(猎物)
species，like
giraffes
and
zebras.
The
United
Nations’
Food
and
Agriculture
Organization
says
15
animals
are
threatened
when
farmers
try
to
16
their
plants
or

Rene
Czudek
works
for
the
UN

says
his
organization
has

that
some

IV.阅读理解
A
Due
to
climate
changes，Arctic
ice
is
breaking
up
earlier
in
the
spring，and
its
area
is
decreasing.This
is
creating
problems
for
polar
bears
that
make
their
homes
off
northern
Alaska
and
in
Hudson
Bay.
Polar
bears
off
Alaska
normally
hunt
and
raise
their
young
on
ice
sheets
that
float
on
the
ocean.But
as
the
ice
has
melted，the
polar
bears
have
been
forced
to
spend
more
time
on
land.There，they
have
begun
to
frequent(常去)
beaches，feeding
on
the
remains
of
whales
caught
by
native
hunters.For
polar
bears，this
food
is
less
nutritious
than
seals
that
they
normally
catch
on
ice
sheets.The
shrinking(减少)
ice
has
also
forced
more
polar
bears
into
the
ocean.In
the
past，they
only
had
to
swim
short
distances
between
ice
sheets.But
as
the
ice
has
shrunk，polar
bears
have
been
forced
to
swim
longer
and
longer
distances
in
the
open
ocean.This
poses
a
severe
danger
during
rough
weather，and
an
increasing
number
of
drowned
polar
bears
have
been
observed.
In
Hudson
Bay，the
ice
breaks
up
three
weeks
earlier
in
the
spring
now
than
it
did
20
years
ago.Polar
bears
on
Hudson
Bay
fast(绝食)
during
the
summer，waiting
for
ice
to
form
in
the
fall
to
hunt.Every
year，the
summer
gets
longer，and
the
bears
get
skinnier.Over
the
past
25
years，the
average
weight
of
the
female
bears
has
dropped
68
kg.This
loss
affects
their
ability
to
reproduce，and
already
the
number
of
births
has
dropped
by
15
percent.Unless
the
bears
can
learn
to
survive
these
climate
changes，these
giants
of
the
ice
may
one
day
disappear.
1．What
is
Arctic
ice
doing
earlier
each
year?
A．It’s
freezing.
B．It’s
hardening.
C．It’s
melting.
D．It’s
expanding.

of
polar
bears
that

time
on
land
in
Alaska?
A．Their
young
are
dying.
B．Their
diet
is
changing.
C．Their
health
is
improving.
D．Their
families
are
growing.
3．What
does
the
writer
imply
about
female
polar
bears
in
Hudson
Bay?
A．They
are
having
fewer
young
now.
B．They
suffer
from
various
sicknesses.
C．They
don’t
need
stronger
protection.
D．They
can’t
find
enough
good
males.
4．In

The
world
celebrates
Earth
Day
every
year
on
April
22.But
one
school
in
Potomac，Maryland
tries
to
honor
Earth
Day
every
day.Very
young
children
are
learning
about
the
environment
and
taking
action
to
show
their
love
for
the
Earth.
A
child’s
world
is
the
world
of
playing.They
love
being
outside
in
the
open
air，running，sliding
and
swinging
on
playground
equipment.But
children
at
St.James
Children’s
School
also
add
to
that
fun
by
picking
up
rubbish
in
the
school.Inside，they
learn
to
save
water
and
electricity.They
also
recycle
and
reuse
things.And
every
spring
they
get
the
soil
ready
to
plant
flowers
and
vegetables
in
the
school
garden.
The
children
at
St.James
range
from
six
weeks
to
six
years
old.The
environmental
study
begins
at
age
two.Rebecca
Boker
teaches
the
children
the
importance
of
taking
care
of
the
Earth.Boker
says
every
day
at
St.James
is
Earth
Day.She
points
to
books
in
all
the
classrooms
and
in
the
library.Most
contain
materials
that
urge
children
to
do
something
to
help
the
environment
and
protect
the
Earth.
St.James
children
observe
the
growth
of
plants
from
seeds
to
sprouts(苗，芽)
in
cups
kept
in
the
classroom.Then
they
watch
the
plants
continue
to
grow
after
placing
them
in
the
garden.The
students
also
observe
the
lifecycle
of
some
insects.After
that，they
know
it
is
their
job
to
respect
their
home
just
like
they
want
others
to
respect
theirs.
But
do
these
very
young
children
really
get
the
message
that
their
teachers
try
to
communicate？Ms
Boker
says
yes.On
April
22
the
kids
at
St.James
will
go
out
to
the
school’s
garden
for
the
yearly
clean?up.But
for
them，Earth
Day
will
continue
for
the
school
days
ahead
as
well.
5．Which
might
be
the
best
title
for
the
passage?
A．Earth
Days
at
St.James
Children’s
School
B．How
to
Celebrate
Earth
Day
C．How
to
Protect
the
Environment
D．Young
Children’s
Love
and
Respect
for
the
Earth
6．When

children
start
the
environmental
study?
A．At
the
age
of
six
weeks.
B．At
two
years
old.
C．At
age
six.

Conservationists
are
breeding(饲养)
lions
in
the
Southern
African
nation
of
Zimbabwe.The
wildlife
experts
hope
to
increase
the
lion
population
to
keep
the
great
cats
from
1
.
In
some
areas，lions
and
human
beings
are
2
control
of
land.Researchers
believe
something
must
be
done
quickly
to
3
the
animals.
The
African
Lion
and
Environmental
Research
Trust(ALERT)
has
more
than
100
4
in
its
breeding
program.Antelope
Park
Farm
is
one
of
two
sites
ALERT
operates
in
Zimbabwe.
Gary
Jones
heads
the
Antelope
Park
Farm.He
says
ALERT
has
become
involved
5
a
sharp
drop
in
the
number
of
lions.His
group
believes
this
has
been
6
mainly
by
humans.There
are
more
people
moving
to
this
area
every
year.The
lions
have
7
land
on
which
to
live.
Gary
Jones
says
the
decrease
in
the
lion
population
affects
the
whole
8
.He
adds
that
other
African
nations
are
also
seeing
the
9
effects
of
this.
There
are
countries，
10
in
central
and
north
Africa，where
the
lion
population
has
reached
a(n)
11
level.Burundi，a
country
of
east?central
Africa，for
instance，does
not
have
lions
in
its
national
parks.
It
12
wants
to
have
lions
reintroduced
back
into
its
national
parks.The
reason
is
that
when
you
take
the
lion
out
of
the
equation(平衡)，suddenly
you
get
all
13
things
start
happening
with
the
balance
of
14
.For
example，you
get
too
many
prey(猎物)
species，like
giraffes
and
zebras.
The
United
Nations’
Food
and
Agriculture
Organization
says
15
animals
are
threatened
when
farmers
try
to
16
their
plants
or
animals.
Rene
Czudek
works
for
the
UN
agency.He
says
his
organization
has
17
a

tool
kit(成套工具)
that
some
countries
are
using
to
