答案A
解析标题归纳题。文章主要讲述了两个孩子在保护环境方面取得的成就,他们是保护地球的英雄。
C
About
20,000
years
ago,much
of
Europe,Asia,North
and
South
America
was
covered
by
huge
sheets
(片)
of
ice,each
many
kilometres
thick.Since
then,the
ice
has
gradually
melted
and
the
ice
sheets
have
retreated.Today,the
only
ice
sheets
on
Earth’s
land
masses
are
found
in
Antarctica
and
Greenland.Some
ice
also
occurs
as
glaciers
in
mountainous
regions
and
as
floating
ice
floes
(浮冰块)
in
the
Arctic
Ocean
and
around
Antarctica.
At
first
sight,these
remote
left-overs
from
the
last
Ice
Age
seem
of
little
importance
for
most
of
us
today.However,nothing
could
be
further
from
the
truth.Many
scientists
believe
that
our
planet
is
warming
as
a
result
of
the
greenhouse
gases
that
we
are
pumping
into
the
atmosphere.If
the
planet
becomes
warmer,the
ice
sheets
will
start
to
melt,causing
sea
level
to
rise
perhaps
several
metres
by
the
end
of
this
century.Such
a
rise
would
cause
widespread
flooding
of
low-lying
coastal
areas
and
threaten
many
large
cities.
Observations
from
space
suggest
that
parts
of
the
major
ice
sheets
are
beginning
to
melt
more
rapidly.Meanwhile,recent
satellite
images
have
also
shown
that
unusually
large
areas
of
sea
ice
have
been
melting
during
the
Arctic
summer.Although
sea
level
will
not
be
affected
by
the
melting
of
the
floating
ice,there
will
be
other
important
environmental
changes.For
example,ice
sheets
act
like
a
mirror,reflecting
sunlight
and
cooling
Earth.If
the
ice
disappears,Earth
is
likely
to
become
warmer
and
major
climate
changes
could
occur.Wildlife
living
in
the
polar
regions
may
also
be
destroyed.

28.What
does
the
underlined
word
“retreated”
in
Paragraph
1
probably
mean?
A.Grown.
B.Reduced.
C.Formed.
D.Disappeared.
答案B
解析词义猜测题。由第一段的描述以及该段中的“theicehasgraduallymelted”和“theonlyicesheetsonEarth’slandmassesarefoundinAntarcticaandGreenland”可知,冰逐渐融化,冰原也变小了,两万年前,欧洲、亚洲、北美洲和南美洲大部分被巨大的冰覆盖着,而现在地球陆地上的冰原只存在于南极洲和格陵兰岛。
29.What’s
most
common
people’s
attitude
towards
the
ice
sheets?
A.Optimistic.
B.Critical.
C.Sincere.
D.Unconcerned.
答案D
解析观点态度题。由第二段中的“Atfirstsight,theseremoteleft-oversfromthelastIceAgeseemoflittleimportanceformostofustoday”可知,乍一看,这些从冰河时代留下来的冰原对我们大多数人来说似乎意义不大,由此可推断,大多数人并不关心冰原的存在。
30.What
would
happen
if
the
greenhouse
gases
continue
to
increase?
A.Vast
amounts
of
land
will
be
flooded.
B.Large
cities
in
the
world
will
disappear.
C.The
sea
level
will
drop
to
its

解析推理判断题。由最后一段中的“Iftheicedisappears,Earthislikelytobecomewarmerandmajorclimatechangescouldoccur.Wildlifelivinginthepolarregionsmayalsobedestroyed”可知,地球上冰层的融化和消失将会带来灾难性的后果。
D
Like
colorful
corals,they
rocked
gently
in
the
ocean
current.Only
these
were
not
beautiful
natural
reefs
grown
over
centuries.They
were
plastic
bags,stuck
to
the
Aegean
Sea
floor
since
a
waste
site
slid
into
the
water
eight
years
ago.
A
team
of
divers
and
environmentalists
pulled
thousands
of
plastic
bags
from
the
water
near
Greece’s
Andros
Island
this
month.The
workers
described
what
they
found
as
a
“gulf
full
of
plastic
corals”.
Seas
polluted
with
plastic
have
become
one
of
the
most
shocking
signs
of
human
damage
to
the
planet.“It
was
a
very
scary
thing
to
see,”said
Arabella
Ross,a
volunteer
diver
with
Aegean
Rebreath.The
group
carries
out
underwater
and
coastal
clean-ups.“It
really
shook
me
and
I
think
it
really
shook
everyone
who
saw
it,”she
added.
The
Mediterranean
is
among
the
seas
with
the
highest
levels
of
plastic
pollution
in
the
world,the
World
Wildlife
Fund
(WWF)
said
in
a
report
in
June.Greece
produces
about
700,000
tons
of
plastic
waste
a
year,or
about
68
kilos
per
person.About
11,500
tons
enter
its
seas
every
year.Almost
70%
of
that
returns
to
the
Greek
coast,one
of
the
longest
in
the
world.The
sea
pollution
off
Andros
is
thought
to
date
back
to
2011,when
heavy
rain
caused
a
waste
site
to
collapse.Most
of
the
waste
fell
into
the
sea.
Aegean
Rebreath
divers
removed
blue,black
and
yellow
plastic
bags
caught
between
reefs
and
among
fish.It
was
“like
the
paradise
of
the
Caribbean
Sea,where
you
find
coral
reefs
everywhere
of
every
color.It
was
the
exact
same
thing,but
instead
of
corals
it
was
bags,”diver
Arabella
Ross
said.
The
team
managed
to
remove
only
a
small
part
of
the
plastic
waste
they
found.They
also
pulled
up
300
kilograms
of
old
fishing
traps—known
as
“ghost
nets”—from
Andros.In
a
separate
operation
in
June
off
Salamina,a
small
island
near
Athens,they
removed
two
tons.
“If
people
are
wondering
where
their
rubbish
ends
up,we
see
it
each
time
we
go
into
the
water,”Ross
said.
【语篇解读】不久前,潜水员发现在希腊安德罗斯岛附近的爱琴海海域积累了大量的塑料垃圾。从远处望去,潜水员仿佛看到了一个色彩缤纷、随着洋流缓缓流动的海底世界。然而,在希腊安德罗斯岛的海床上,人们并没有发现任何植物——取而代之的是数万吨的塑料废物,在这里堆积如山,形成了一种“珊瑚礁”。
32.What
does
the
underlined
word“it”(Para.3)
most
probably
refer
to?
A.The
Aegean
Sea.
B.Plastic

D.The

答案B
解析代词指代题。根据上文的“Seaspollutedwithplastichavebecomeoneofthemostshockingsignsofhumandamagetotheplanet.”可知,此处的it指的是上文提到的塑料污染。
33.What
is
believed
to
be
the
start
of
the

A.Collapse
of
a

B.Extremely
bad

C.Waste
thrown
away
by

produced
by
the
Greeks.
答案A
解析细节理解题。根据第四段的“TheseapollutionoffAndrosisthoughttodatebackto2011,whenheavyraincausedawastesitetocollapse.Mostofthewastefellintothesea.”可知,污染的开始是垃圾场的坍塌。
34.Where
does

according
to
Ross?
A.The
oceans.
B.In
the
fields.
C.In

D.The
waste
treatment

答案A
解析推理判断题。根据Ross所说的话“Ifpeoplearewonderingwheretheirrubbishendsup,weseeiteachtimewegointothewater”可知,垃圾最终进入了海里。
35.What

答案A
解析主旨大意题。通读全文可知,潜水员在水下仿佛看到了一个色彩缤纷、随着洋流缓缓流动的海底世界。但是,在希腊安德罗斯岛的海床上,人们并没有发现任何植物——取而代之的是数万吨的塑料废物,在这里堆积如山,形成了一种“珊瑚礁”。由此可知,A项可作为本文的标题。
第二节(共5小题;每小题2.5分,满分12.5分)
阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
Our
planet
is
always
changing
and
its
systems
are
constantly
working
together
to
keep
a
kind
of
balance. 36 .?
All
living
things
are
connected
to
each
other
in
ecosystems
by
food
chains
and
food
webs. 37 .Herbivores
(species
that
don’t
eat
meat)
get
energy
by
eating
plants.Carnivores
(species
that
eat
meat)
get
energy
by
eating
herbivores.This
is
how
energy
flows
through
all
ecosystems—starting
from
the
sun.?
38 ,the
survival
of
the
entire
system,along
with
every
living
thing
that
depends
on
it
for
survival,hangs
in
the
balance.For
example,if
someone
decides
to
spray
a
poisonous
pesticide
on
plants
to
keep
bugs
from
eating
them,then
lizards
may
accidentally
take
in
that
poison
when
they
eat
the
plants
and
cats
may
be
poisoned,too,when
they
catch
and
eat
the
lizards. 39 .Rats
carry
diseases
that
are
even
more
dangerous
for
humans.?
40 .If
the
eruption
is
very
big,it
could
do
a
lot
of
damage
besides
killing
thousands
of
people.A
volcanic
eruption
spreads
huge
amounts
of
ash
and
gases
into
the
atmosphere
and
around
the
globe,which
could
cause
temperatures
worldwide
to
fall.And
when
temperatures
change
dramatically
like
this,it
affects
crop
patterns
and
could
lead
to
massive
food
shortages.?
A.Plants
get
energy
from
the
sun
B.Another
example
is
when
a
volcano
erupts
C.When
any
one
part
of
an
ecosystem
chain
breaks
D.If
we
don’t
take
measures
to
protect
our
environment
E.With
no
cats
around,the
rat
population
could
explode
F.All
forms
of
life
depend
on
this
balance
for
their
existence
G.These
gases
help
keep
the
world
from
being
too
hot
or
too
cold
答案与解析
【语篇解读】我们的星球总是在变化,它的系统总是在一起工作以保持某种平衡。当生态链的任何一部分断裂时,整个生态系统就会受到威胁。
36.F 上文提到“我们的星球总是在变化,它的系统总是在一起工作以保持某种平衡”,F项“所有的生命形式为了生存都依赖于这种平衡”可承接上文。
37.A 上文提到“所有生物都通过食物链和食物网相互连接在生态系统中”,下文应是举例说明,A项便是举例说明。
38.C 根据下文所提到的内容来看,所填的句子是当生态链的任何一部分断裂时所发生的状况,所以选C项。
39.E 上文提到猫,下文提到老鼠。所以所填的是承接上下文的句子,E项“没有猫,老鼠就会泛滥”可承接上下文。
40.B 根据“Iftheeruptionisverybig...”可知,此处是以火山爆发为例子,所以选B项。

45
his

46
a

likes
me.I
hope
to
have
a
second
47 .I
can
prove
what
a
good
friend
I
can
be.”?

48
a
map
showing

way
from
the
church
to
the
hospital,walked
to
the
window,and
let
the
balloon
fly
away,carrying
his
49
into
the
sky.The
balloon
was
heading
straight
to
a
telephone
pole,but
a
gentle
50
blew
it
away
just
in
time.Soon
it
disappeared
out
of
51 .?
The
next
day,a
girl
he
had
52
met
before
came
to
visit
him.“I
find
the
balloon,”
she
said.“You
are
lonely?”
He
just
nodded
his
head,too
53
to
talk.“I
am
lonely
too.My
family
come
from
Afghanistan
and
I
can’t
speak
English
well.”
She
smiled.“I
bring
a
gift
to
you.”
She
handed
him
a
box
of
54 .?
Normally,he
would
have
made
fun
of
her
55
English
and
her
long,brown
robe
(长袍),but
he
knew
better.He
smiled
and
offered
her
the
first
chocolate.?

What
makes
the

red
and
causes
thousands
of
fish

die?As
far
back
as
anyone
could
remember,the
blame
was
placed
on
the
“red
tides”.In
1947,scientists
finally
connected
the
red

with
a
microscopic

答案与解析
【语篇解读】这是一篇说明文。主要介绍了微小的海洋生物腰鞭毛虫并阐述了其对海洋产生的影响。
56.called 考查非谓语动词。根据句子结构可知,设空处需用非谓语动词;organism和call构成被动关系,故用过去分词作后置定语。
57.that 考查连词。根据句子结构可知,设空处引导状语从句;so+adj./adv.+that...表示“如此……以至于……”,故填that。
58.a 考查冠词。根据句子结构可知,设空处需用冠词修饰名词drop,由于single以辅音音素开头,故填a。adropofwater“一滴水”。
59.freely 考查副词。设空处修饰动词,故用其副词形式。
60.forms 考查名词复数。根据设空处前的all可知填forms。
61.are 考查主谓一致。全文时态为一般现在时,设空处也需用一般现在时;and连接两个表示不同意义的名词air和water作主语,谓语动词需用复数形式,故填are。
62.amazing 考查形容词。设空处修饰名词speed,故用其形容词形式,表示“令人惊奇的”,所以填amazing。
63.tobecovered 考查非谓语动词。appeartodosth“似乎要做某事”;Thesurfaceofthewater和cover之间构成被动关系。故填tobecovered。
64.for 考查介词。befitfor...为固定词组,表示“适合……”。
65.poisonous 考查形容词。become是系动词,设空处需用其形容词形式作表语,所以填poisonous。

第二节(满分25分)
阅读下面短文,根据其内容写一篇
60词左右的内容概要。
Family
problems
are
a
universal
phenomenon,and
they
can
always
cause
people
pain,especially
around
family-centered
times,like
holidays.However,there
are
ways
to
solve
the
problems.Life
is
too
short
to
waste.How
a
person
approaches
the
family
members
and
what
he
says
can
make
a
big
difference.
If
the
family
members
are
arguing,waiting
until
everyone
calms
down
can
help
deal
with
the
argument.A
person
shouldn’t
discuss
the
family
problem
when
he
is
still
feeling
upset
or
emotional.If
he
waits
even
a
single
night,the
intensity(强度)
of
the
emotion
is
likely
to
calm
down
somewhat,even
if
he
is
still
unhappy.So
it
is
advised
that
he
should
wait
rather
than
react
emotionally.If
he
takes
a
step
back
and
gives
himself
some
time
to
think
before
dealing
with
the
problem,he
will
deal
with
it
wisely.
There
are
lots
of
people
who
want
to
send
off
a
text
or
an
email
and
wish
they
could
take
things
back.Actually,the
tone(语气)
can
be
easily
misunderstood
by
electronic
communication.The
man
who
sends
off
a
text
message
or
email
might
not
think
he
sounds
angry
to
the
person
receiving
it.Instead
of
sending
off
a
text,pick
up
the
telephone,or
better
yet,arrange
in-person
communication.Electronic
communication
means
people
lose
the
true
meaning
of
body
language,which
can
convey
feelings
and
reduce
the
sting(刺痛)
of
a
painful
conversation.
As
the
saying
goes,“Blood
is
thicker
than
water.”
People
can
choose
their
friends,but
not
their
family.You
might
be
able
to
cut
family
members
out,but
it
could
cause
you
more
pain
down
the
road.Understanding
that
family
members
have
faults,but
they
can
still
love
their
families,is
the
first
step
towards
dealing
with
problems.Accept
your
own
faults,too.

With
global
warming
and
melting
ice,it
isn’t
easy
being
a
polar
bear
anymore.Some
studies
have
predicted
that
polar
bears
could
die
out
by
the
end
of
the
century.The
good
news
is
not
all
researchers
think
the
bears
are
absolutely
disappearing.Scientists
at
the
American
Museum
of
Natural
History
(AMNH)
have
published
a
new
paper
indicating
that
things
might
not
be
as
bad
for
polar
bears
as
some
scientists
expect.
To
understand
the
reason
for
the
researchers’
cautious
optimism,we
must
first
understand
the
factors
that
are
threatening
the
polar
bear’s
existence.Polar
bears
consume
a
diet
of
mainly
young
seals.In
order
to
hunt
these
seals,polar
bears
need
to
rest
at
the
top
of
sea
ice—the
same
ice
that
is
increasingly
melting
for
most
of
the
year
thanks
to
climate
change.In
another
50
years,experts
expect
that
the
Arctic
will
be
too
warm
for
sea
ice
to
form
for
half
of
the
year,leaving
polar
bears
without
a
reliable
food
source
and
in
serious
danger
of
starvation.
As
it
turns
out,alternative
food
sources
for
the
polar
bears
aren’t
completely
out
of
the
question.For
as
long
as
biologists
have
tailed
after
the
animals,they’ve
seen
polar
bears
eating
animals
found
on
land
like
caribou
(驯鹿)
and
snow
geese—as
well
as
the
snow
geese’s
eggs.
Can
polar
bears
actually
survive
on
these
alternative
food
sources
for
long
periods
of
time?To
figure
this
out,researchers
calculated
the
nutrients
that
a
caribou
and
snow
geese
diet
would
provide.They
found
that
even
adult
male
polar
bears
would
be
able
to
obtain
more
calories
than
they
would
burn
in
hunting
these
meals.Moreover,the
food
would
provide
the
food
necessary
to
avoid
starvation
during
the
summer
months.
Unfortunately,not
all
polar
bears
have
tended
to
seek
food
on
land.That
said,the
researchers
expect
that
necessity
would
push
more
polar
bears
to
hunt
on
land
to
avoid
starvation.They
also
expect
that
the
bears
could
learn
from
their
fellow
bears
how
to
hunt
on
land
until
the
practice
becomes
second
nature.

Over
a
hundred
years
ago
in
1911,something
strange
was
found
in
the
glaciers
of
Antarctica.Grilffith
Taylor—an
Australian
geologist,had
discovered
a
blood
red
stream
pouring
out
of
the
ice
cascades
(瀑布)
of
Taylor
Glacier!Popularly
known
as
the
Blood
Falls,scientists
had
not
been
able
to
find
the
reason
behind
the
blood
red
liquid
flowing
through
the
ice—until
recently.The
mystery
of
the
Blood
Falls
had
finally
been
solved.
When
these
falls
were
first
discovered,scientists
had
believed
that
the
red
colour
came
from
a
large
amount
of
red
algae
(海藻)
concentrated
in
the
water.Red
algae
contain
a
pigment
(色素)
which
reflects
red
light,making
the
algae
appear
red.
This
theory
made
sense,until
it
was
later
found
that
algae
do
not
play
a
part
in
the
red
color
of
the
flowing
liquid
at
all.What
really
causes
Taylor
Glacier’s
waters
appear
blood
red,is
the
presence
of
iron
oxide
in
the
liquid.The
waters
of
the
blood
falls
are
rich
in
salt
and
iron
content,and
when
this
water
comes
in
contact
with
the
air,it
turns
red—just
like
rust!The
water
in
these
falls
is
often
referred
to
as
“brine”
by
scientists
because
of
the
high
salt
content
in
the
water.
This
reasoning
behind
the
red
colors
of
the
falls
was
found
back
in
2003.However,the
entire
mystery
had
not
yet
been
solved.How
is
it
then,that
the
Blood
Falls
are
not
frozen?
Researchers
at
the
University
of
Colorado
and
University
of
Alaska
found
that
inside
the
glacier,there
was
a
network
of
channels
and
reservoirs
that
move
the
water
around.Salt
water
has
a
lower
freezing
temperature.In
addition,when
any
substance
undergoes
a
change
in
state,it
gives
off
heat.Therefore,the
brine
actually
warms
itself
up
while
it’s
freezing!How
this
works,is
that
when
the
brine
is
flowing
through
the
Taylor
Glacier,some
of
it
does
freeze.As
a
result
of
changing
state
from
liquid
to
ice,the
brine
gives
off
heat.This
heat
is
enough
to
keep
the
rest
of
the
brine
in
liquid
form,which
is
why
it
flows
out
of
the
glacier.

sunlight.
D.Because
the
air
is
thin
and
rare
in
Antarctica.
答案A
解析细节理解题。根据第三段的第三句可知,因为血瀑布富含盐分和铁,当水接触空气时,就会像铁锈一样变红。
3.What
is
the
main
reason
for
the
Blood
Falls’
not
freezing?
A.The
water
continued
flowing
constantly.
B.There
is

salt
in
the
water.
C.The
brine
gives
off
heat
while
freezing.
D.Temperatures
aren’t
high
enough
for
flowing
water.
答案C
解析细节理解题。根据第五段最后一句可知,当由液态向冰态变化时,盐水放出热量。这种热量足以使其余的盐水保持液态,这就是它不结冰的原因。
4.What
is
the
passage
mainly
about?
A.The
discovery
of
the
blood
glacier.
B.The
birth
of
the
Taylor
Glacier.
C.The
flowing
red
water
in
Antarctica.
D.The
mystery
of
the
Blood
Falls.
答案D
解析主旨大意题。通读全文可知,1911年澳大利亚地质学家在南极洲的冰川中发现了血瀑布。众所周知,科学家一直无法找到冰川中的红色液体不结冰的原因。直到最近,血瀑布的秘密终于被揭开了。D项“血瀑布之谜”最能概括文章的内容,体现文章的主旨。

This
woodland
construction
is
the
world’s
biggest
beaver
dam,which
at
2,790
feet
in
length
and
more
than
twice
the
length
of
the
Hoover
Dam,and
can
be
seen
from
space.
The
mammals
use
trees,mud
and
stones
to
make
a
type
of
moat(壕沟)
where
they
can
use
their
swimming
skills
to
evade(躲避)
any
predators(食肉动物).The
families
of
beavers
live
in
lodges
on
the
dams
and
spend
their
days
adding
to
and
repairing
the
incredible
structures.While
beaver
dams
are
often
found
to
be
around
1,500
feet
in
length,this
one
has
surprised
biologists
because
of
its
length.The
dam
is
located
on
the
southern
edge
of
Wood
Buffalo
National
Park
in
northern
Alberta,Canada.It
is
thought
that
several
beaver
families
joined
forces
to
create
the
big
dam
that
contains
thousands
of
trees
and
must
have
taken
many
months
to
complete.
The
dams
are
an
important
part
of
the
ecology
and
wider
environment,and
climate
change
can
be
judged
by
the
spread
of
the
dams.
Sharon
Brown,a
biologist
from
Beavers:
Wetland
and
Wildlife,an
educational
organisation
in
North
America,said:“Beavers
build
dams
to
create
a
good
habitat.They
are
very
agile(灵活的)
in
the
water,but
they’re
a
bit
slow
moving
on
land.”
“They
create
a
habitat
with
lots
of
water,like
a
moat,around
their
lodges
so
they
can
swim
and
dive,and
keep
one
step
ahead
of
predators.”
“They
also
use
water
to
move
the
trees
they
use
in
their
dams,because
it
is
easier
floating
branches
on
the
water
than
dragging
them
over
land.”
“Their
dams
are
also
beneficial
because
they
slow
the
flow
of
water
leading
to
less
drought
and
less
flooding.And
when
plant
matter
dies
in
water,it
turns
into
peat(泥炭)
and
that
is
one
of
the
best
ways
for
storing
carbon
dioxide.”
