三、阅读理解
??
It
is
true
that
quite
a
few
most
respected
scientific
authorities
have
confirmed
that
the
world
is
becoming
hotter
and
hotter.
There
is
also
strong
evidence
that
humans
are
contributing
to
the
warming.
Countless
recent
reports
have
proved
the
same
thing.
For
instance,
a
2012
summary
about
the
climate
science
by
the
Royal
Society
noted
that,
"The
global
warming
over
the
last
half-century
has
been
caused
mainly
by
human
activity."
???
You
may
not
believe
that
humans
could
change
the
planet's
climate,
but
the
basic
science
is
well
understood.
Each
year,
billions
of
tons
of
greenhouse
gases
are
released
into
the
atmosphere
because
of
human
activity.
As
has
been
known
for
years,
these
gases
hold
heat
that
would
otherwise
escape
to
space,
wrapping
the
planet
in
an
invisible
blanket.
???
Of
course,
the
earth's
climate
has
always
been
changing
due
to
"natural"
factors(因素)
such
as
volcanic
eruption
or
changes
in
solar,
or
cycles
concerning
the
Earth's
going
around
the
sun.
According
to
the
scientific
research,
however,
the
warming
observed
by
now
matches
the
pattern
of
warming
we
would
expect
from
a
build-up
of
greenhouse
gas
in
the
atmosphere—not
the
warming
we
would
expect
from
other
possible
causes.
???
Even
if
scientists
did
discover
another
reasonable
explanation
for
the
warming
recorded
so
far,
that
would
give
birth
to
a
difficult
question.
As
Robert
Henson
puts
it,
"If
some
newly
discovered
factor
is
to
blame
for
the
climate
change,
then
why
aren't
carbon
dioxide
and
the
other
greenhouse
gases
producing
the
warming
that
basic
physics
tells
us
they
should
be?"
???
The
only
way
to
prove
with
100%
certainty
that
humans
are
responsible
for
global
warming
would
be
to
run
an
experiment
with
two
identical
Earths—one
with
human
influence
and
one
without
That
obviously
isn't
possible,
and
so
most
scientists
are
careful
not
to
state
human
influence
as
an
absolute
certainty.
1.
In
most
scientists'
opinion,
the
global
warming
is
mainly
caused
by
_____.
A.
solar
activities
B.
volcanic
activities
C.
natural
factors
D.
human
factors
2.
The
passage
is
developed
by_____.
A.
giving
typical
examples
B.
following
the
order
of
space
C.
analyzing
a
theory
and
arguing
it
D.
comparing
and
finding
differences
3.
We
can
reasonably
know
from
the
passage
that
_____.
A.
"natural"
factors
also
contribute
to
changes
of
earth's
climate
B.
greenhouse
gases
also
have
some
benefits
to
the
earth
C.
there
is
another
planet
that
is
exactly
the
same
as
the
earth
D.
increasing
temperature
cannot
be
proved
with
100%
certainty
4.
Which
of
the
following
can
be
the
best
title?
A.
Are
All
the
Scientists
Really
Scientific?
B.
Where
Is
Global
Warming
Leading
Us
to?
C.
Are
Humans
Definitely
Causing
Global
Warming?
D.
What's
Relation
of
Global
Warming
and
Greenhouse
Gases?
四、语法填空
The
polar
bear
is
found
in
the
Arctic
Circle
and
some
big
land
masses
as
far
south
as
Newfoundland.
While
they
are
rare
north
of
88°,
there
is
evidence
①_____
they
range
all
the
way
across
the
Arctic,
and
as
far
south
as
James
Bay
in
Canada.
It
is
difficult
to
figure
out
a
global
population
of
polar
bears
as
much
of
the
range
has
been
②_____
(poor)
studied;
however,
biologists
calculate
that
there
are
about
20,000—25,000
polar
bears
worldwide.
Modern
methods
③_____
tracking
polar
bear
populations
have
been
employed
only
since
the
mid-1980s,
and
are
expensive
④_____
(perform)
consistently
over
a
large
area.
In
recent
years
some
Inuit
people
in
Nunavut
⑤_____
(report)
increases
in
bear
sightings
around
human
settlements,
leading
to
a
⑥_____
(believe)
that
populations
are
increasing.
Scientists
have
responded
by
⑦_____
(note)
that
hungry
bears
may
be
congregating(聚集)
around
human
settlements，
leading
to
the
illusion(错觉)
that
populations
are

(high)
than
they
actually
are.
Of

nineteen
recognized
polar
bear
subpopulations，

三、答案：1-4DCAC
解析：1.细节理解题。根据第一段第二句和最后一句可知,人类因素是气候变暖的主要原因。故选D项。
2.篇章结构题。纵观全文,第一段提出人类活动因素是全球气候变暖的主要原因。接着分析讨论为什么说人类活动可以导致气候变暖。文章按照先分析理论再论证的方式行文。故选C项。
3.推理判断题。根据第三段第一句可推断出A项。
B和C找不到相应信息点;根据文章首句和文章最后一段可知D项也不符合。地球变暖是早已经被证实的,不能完全证实的是全球变暖是否是因为人类的活动。故选A项。
4.标题归纳题。文章开始提出人类活动因素导致了全球气候变暖,然后分析讨论为什么人类活动会导致全球气候变暖。文章通篇都贯穿“人类的活动”。C项“的确是人类造成了全球气候变暖吗?”适合做文章标题。故选C项。
四、答案：①that;
②poorly;
③of/for;
④to
perform;
⑤have
reported;
⑥belief;
⑦noting;
⑧higher;
⑨the;
⑩are
解析：①考查同位语从句。根据句子结构分析可知,空格后为同位语从句,解释说明中心词evidence的内容,故填that。
②考查副词。根据句意和分析结构可知,此处用副词poorly修饰谓语动词“has
been
studied”，
poorly意为
“不好地”。故填poorly。
③考查介词。method
of/for
doing
sth.意为
“做……的方法”,为固定结构。故填of/for。
④考查非谓语动词。句意:追踪北极熊数量的现代方法从二十世纪八十年代中期才开始被使用,并且在如此大区域内持续使用是昂贵的。主系表结构之后常用不定式做原因或目的状语。故填to
perform。
⑤考查时态和主谓一致。根据上下文语境,尤其是时间状语“In
recent
years”可知,主句用现在完成时,主语some
Inuit
people为复数意义,故填have
reported。
⑥考查名词。根据其前不定冠词和其后的同位语从句可知,空格处用名词形式,故填belief。
⑦考查非谓语动词。根据其前介词“by”可知,
此处用动名词做宾语,故填noting。
⑧考查形容词比较级。根据其后“
than
they
actually
are”可知,此处为形容词的比较级,故填higher。
⑨考查定冠词。此处为特指,意为“在已识别的十九个北极熊亚种群中”,故填the。
⑩考查时态和主谓一致。根据"three
are
declining"可知此处要用复数谓语,时态为一般现在时,故填
are。
