三、阅读理解
In
the
last
50
years,
sea
surface
temperatures
around
Antarctica
have
risen
by
1—2°C,
which
is
more
than
twice
the
global
average.
Loss
of
species
Global
warming
could
basically
change
the
ecosystem,
leading
to
the
loss
of
some
species.
Sharks
are
going
to
arrive
in
Antarctica
as
long
as
the
warming
trend
continues,
a
bit
more
slowly
than
crabs—crabs
are
going
to
get
there
first,
but
once
they
do
get
there
they
are
able
to
eat
the
organisms
that
live
there.
???
Professor
Wilga
said
the
arrival
of
sharks
and
shell-crushing
bony
fishes
would
lead
to
great
changes
in
the
number
and
proportions
(比例)of
species
found
there.
Shrimp,
ribbon
worms
and
brittle
stars
are
likely
to
be
the
most
attackable
to
population
declines.
Animals
living
in
shallow
waters
in
Antarctica
are
unique
on
Earth
today
because
they
evolved
(进化)
in
a
very
cold
environment
over
tens
of
millions
of
years.
Extreme
conditions
In
the
course
of
a
process
we
call
Antarctic
cooling
that
started
about
40
million
years
ago,
all
major
seafloor
predators
such
as
sharks
and
crabs
went
extinct
in
Antarctica
because
they
were
not
able
to
deal
with
these
extreme
conditions.
However,
today
global
warming
is
removing
barriers
to
invasions
and
we've
seen
recently
that
crabs,
especially
king
crabs,
are
on
the
doorstep
of
Antarctica—they
can
potentially
re-invade
the
shallow
waters
if
warming
continues.
Urgent
local
and
global
actions
are
needed
to
protect
this
last
environment
and
measures
are
needed
to
stop
alien
species
being
brought
in
through
ships.
Strange
creatures
Animals
that
live
on
the
seafloor
of
Antarctica
are
some
of
the
strangest
creatures
on
Earth.
The
extreme
cold
and
darkness
has
presented
huge
challenges
to
marine
life
over
the
passage
of
time,
leading
to
the
evolution
of
fish
equipped
with
anti-freeze
proteins
in
their
blood.
1.
How
will
these
alien
species
affect
the
ecosystem
in
Antarctica?
A.
They
will
change
the
extremely
cold
conditions
in
Antarctica.
B.
They
will
change
the
numbers
and
proportions
of
species
in
Antarctica.
C.
The
sea
surface
temperature
of
Antarctica
will
rise
more
quickly.
D.
The
number
of
shrimp
and
ribbon
worms
will
increase
in
Antarctica.
2.
How
does
the
author
feel
about
the
alien
species'
invasion
to
Antarctica?
A.
Worried.
B.
Doubtful.
C.
Satisfied.
D.
Excited.
3.
Which
is
the
best
title
of
this
passage?
A.
Creatures
in
Antarctica
Are
Unique
B.
The
Extreme
Conditions
in
Antarctica
C.
Alien
Species
Are
Not
Found
in
Antarctica
D.

Antarctic
Ecosystem
四、语法填空
??
Macquarie
Island
was
a
beautiful
place?①_____
its
native
inhabitants,
including
royal
②_____
(penguin),
king
penguins,
and
elephant
seals,
existed?③_____
harmony
with
their
natural
habitat
for
thousands
of
years.
However,
in
1810,
humans
④_____
(arrive)
on
the
island
with
rats
and
mice.
They
quickly
took
over
the
island,
eating
birds'
eggs
and
⑤_____
(attack)
baby
birds.
Cats
⑥_____
(bring)
to
control
the
rats
and
mice,
but
they
also
liked
eating
birds.
Meanwhile,
the
exploding
rabbit
population
provided
food
for
cats,
meaning
that
the
number
of
cats
also
increased
⑦_____
(rapid).
This
in
turn
led
to
more
cats
hunting
birds.
The
end
result
was
that
parakeets,
once
large
in
number
and
native
to
the
island,
died?⑧_____
in
1891.
???
A
vims
⑨_____
(release)
onto
the
island
caused
rabbits
to
decrease,
but
the
cats,
without
enough
rabbits
to
eat,
killed
native
birds
for
food.
Although
all
the
cats
were
caught
in
2000,
rats
and
mice
exploded
once
again.
Besides,
the
rabbits'
⑩_____
(dig)
caused
some
land
to
collapse
and
killed
many
penguins.
???
A
programme
was
started
to
tackle
those
problems.
This
intervention
is
a
long
process,
but
we
humans
owe
it
to
the
island
to
give
it
a
happy
ending.

2.推理判断题。根据倒数第二段可知,需要采取紧急的地方和全球性措施来保护南极洲的环境。由全文中作者介绍和议论外来物种侵入南极洲生态的后果可推知,作者对此感到担忧。故选A项。
3.标题归纳题。文章通篇都是讲述外来物种入侵给南极洲带去的后果,故D选项“外来物种可能改变南极洲的生态系统”适合做文章标题。故选D项。
四、答案：①

②考查名词复数。根据后面的penguins和seals可知，应填penguin的复数形式。
③考查介词。in
harmony
with与……协调一致，故应填in。
④考查动词的时态。句意:然而，在1810年，人类带着大老鼠和老鼠来到了岛上。根据时间状语in
1810可知，本句时态应为一般过去时。
⑤考查非谓语动词。此处应用attacking与eating并列作伴随状语。
⑥考查时态和语态。句意:猫被带来控制大老鼠和老鼠，但它们也喜欢吃鸟。根据上下文可知，应用一般过去时，且Cats与bring之间为被动关系，故应用一般过去时的被动语态。
⑦考查副词。设空处修饰动词increased,应填副词形式，故填rapidly。
⑧考查固定短语。die
out灭绝。
⑨考查非谓语动词。句意:一种病毒被释放到岛上，导致兔子数量减少，但是猫没有足够的兔子吃，就杀当地的鸟类作为食物。根据句意和句子结构可知，
release和virus之间是被动关系，应用过去分词形式作后置定语。
⑩考查动名词。设空处作主语，应用动名词形式，故填digging。
