56.A
此題難度不大,根據(jù)題干中的“SiliconValley”可定位第一段,第一段尾句“istheresomethinguniqueaboutit?”直接把答案引向第二段。精讀第二段“itwouldn’tbesurprisingifitwerehardtoreproduceinothercountries”,可知該句與A選項(xiàng)“Itssuccessishardtocopyanywhereelse.”為同義替代關(guān)系,故選A,其他三項(xiàng)均為無中生有。57.B
此題難度不大,根據(jù)題干中“Miami”可定位至原文第五段,該段表明邁阿密只有有錢人,而缺乏“癡迷于技術(shù)的人”,因此無法成為科技中心,該含義對(duì)應(yīng)B選項(xiàng),為統(tǒng)一替代關(guān)系,選項(xiàng)中的“therightkindoftalents”替代了原文的“nerds”。58.A
此題難度不高,根據(jù)題干中的“Carnegie-Mellon”和“Stanford”,“Berkeley”,“MIT”輕易定位到原文第六段,第六段段位拋出問題,因此順勢(shì)往第七段找答案。第七段中詳細(xì)描述了卡內(nèi)基梅隆大學(xué)所在的匹茲堡的不一樣之處:“Theweatheristerrible”,“richpeopledon’twanttoliveinPittsburghorIthaca”,這些信息都指向了A選項(xiàng),為高度概括關(guān)系。59.D
該題難度較高,根據(jù)題干中的“Boston”可定位至原文的第七段。原文提到Boston的句子為“asthereisinBoston”,as在這裏表對(duì)比,意為“波士頓卻有”,那么前文一定指出了匹茲堡沒有某物,因此關(guān)鍵句在于詳細(xì)是什么,故往前文查找,發(fā)現(xiàn)前文提到的是“andthere’snointerestingoldcitytomakeupforit”,意思是匹茲堡不僅天氣惡劣,并且也沒有有趣的老城區(qū),不過波士頓卻與之相反,固選擇D,表達(dá)“波士頓有著諸多歷史古跡”。60.C
本題難度不高,根據(jù)關(guān)鍵名詞概念“startupinvestors”可定位到原文最終一段,原文清晰地表述了,startupinvestors不僅可以提供資金協(xié)助,還能提供諸多提議,因此C選項(xiàng)“他們不僅能提供資金”是最佳的答案,和原文關(guān)系為高度概括。第二篇

61.C
該題難度不大,根據(jù)“l(fā)ike-mindedpeople”定位到首段,首段指出此類人可以給人信息并令人感到舒適,背面用“unfortunately”表轉(zhuǎn)折,背面的表述“這種舒適會(huì)讓你意識(shí)不到你可以擴(kuò)大你的企業(yè)和事業(yè)”,對(duì)應(yīng)C選項(xiàng),同義替代。62.B
本題不難。根據(jù)關(guān)鍵名詞“l(fā)eaders”定位到第三段,作者給leader的提議是“雖然建立一種自由言論的環(huán)境不輕易,不過俗話說靈感從爭(zhēng)論中迸發(fā)”,意思是領(lǐng)導(dǎo)者需要建立這樣能的環(huán)境,固選擇B項(xiàng),高度概括。63.A
本題難度不大。根據(jù)關(guān)鍵信息“purposeofholdingadebate”定位到原文倒數(shù)第三段,原文“objective”對(duì)應(yīng)“purpose”,背面跟的即為答案:“isnottowinbuttogetthetruththatwillallowyoutomovefaster,farther,andbetter.”,對(duì)應(yīng)A選項(xiàng)。64.D
該題難度較大。根據(jù)關(guān)鍵信息“fiercedebate”定位到原文倒數(shù)第二段,原文給出觀點(diǎn)“用微笑和風(fēng)趣表明這是一種友好的討論,大家的目的都是同樣的”,對(duì)應(yīng)D選項(xiàng),該題強(qiáng)干擾項(xiàng)為B,B選項(xiàng)中的“respect”輕易讓同學(xué)們產(chǎn)生好感從而錯(cuò)選B,而實(shí)際上B選項(xiàng)錯(cuò)在“other’sbeliefs”上,原文并沒有提到尊重他人的信念和觀點(diǎn),屬于無中生有。65.D
根據(jù)題干“rival”對(duì)應(yīng)到最終一段的“sparringpartners”,原文給出“讓他們懂得對(duì)他們的付出你很感謝”,對(duì)應(yīng)D選項(xiàng)“肯定他們的付出”,為同義替代關(guān)系。PassageOne

Passage
One
Questions
56
to
60
are
based
on
the
followingpassage.
Across
the
rich
world,
well-educated
peopleincreasingly
work
longer
than
the
less-skilled.
Some65%
of
American
men
aged
62-74
with
aprofessional
degree
are
in
the
workforce,
comparedwith
32%
of
men
with
only
a
high-school
certificate.This
gap
is
part
of
a
deepening
divide
between
thewell-educated
well-off
and
the
unskilled
poor.
Rapidtechnological
advance
has
raised
the
incomes
of
thehighly
skilled
while
squeezing
those
of
the
unskilled.
The
consequences,
for
individuals
andsociety,
are
profound.
The
world
is
facing
an
astonishing
rise
in
the
number
of
old
people.
And
they
will
live
longerthan
ever
before.
Over
the
next
20
years
the
global
population
of
those
aged
65
or
more
willalmost
double,
from
600
million
to
1.1
billion.
The
experience
of
the
20th
century,
when
greaterlongevity
(長(zhǎng)壽)
translated
into
more
years
in
retirement
rather
than
more
years
at
work,
haspersuaded
many
observers
that
this
shift
will
lead
to
slower
economic
growth,
while
the
swellingranks
of
pensioners
will
create
government
budget
problems.
But
the
notion
of
a
sharp
division
between
the
working
young
and
the
idle
old
misses
a
newtrend,
the
growing
gap
between
the
skilled
and
the
unskilled.
Employment
rates
are
fallingamong
younger
unskilled
people,
whereas
older
skilled
folk
are
working
longer.
The
divide
ismost
extreme
in
America,
where
well-educated
baby-boomers(二戰(zhàn)後生育高峰期出生的美國(guó)人)areputting
off
retirement
while
many
less-skilled
younger
people
have
dropped
out
of
theworkforce.
Policy
is
partly
responsible.
Many
European
governments
have
abandoned
policies
that
used
toencourage
people
to
retire
early.
Rising
life
expectancy(預(yù)期壽命),
combined
with
thereplacement
of
generous
defined-benefit
pension
plans
with
less
generous
defined-contribution
ones,
means
that
even
the
better-off
must
work
longer
to
have
a
comfortableretirement.
But
the
changing
nature
of
work
also
plays
a
big
role.
Pay
has
risen
sharply
for
thehighly
educated,
and
those
people
continue
to
reap
rich
rewards
into
old
age
because
thesedays
the
educated
elderly
are
more
productive
than
the
preceding
generation.
Technologicalchange
may
well
reinforce
that
shift:
the
skills
that
complement
computers,
frommanagement
knowhow
to
creativity,
do
not
necessarily
decline
with
age.注意:此部分試題請(qǐng)?jiān)诖痤}卡2上作答。56.

TwoQuestions
61
to
65
are
based
on
the
followingpassage.Some
of
the
world’s
most
significant
problems
neverhit
headlines.
One
example
comes
from
agriculture.Food
riots
and
hunger
make
news.
But
the
trendlying
behind
these
matters
is
rarely
talked
about.This
is
the
decline
in
the
growth
in
yields
of
some
ofthe
world’s
major
crops.
A
new
study
by
the
University
of
Minnesota
and
McGill
University
inMontreal
looks
at
where,
and
how
far,
this
decline
is
occurring.The
authors
take
a
vast
number
of
data
points
for
the
four
most
important
crops:
rice,
wheat,corn
and
soyabeans(大豆).
They
find
that
on
between
24%
and
39%
of
all
harvested
areas,
theimprovement
in
yields
that
took
place
before
the
1980s
slowed
down
in
the
1990s
and
s.There
are
two
worrying
features
of
the
slowdown.
One
is
that
it
has
been
particularly
sharp
inthe
world’s
most
populous(人口多的)countries,
India
and
China.
Their
ability
to
feed
themselveshas
been
an
important
source
of
relative
stability
both
within
the
countries
and
on
world
foodmarkets.
That
self-sufficiency
cannot
be
taken
for
granted
if
yields
continue
to
slow
down
orreverse.Second,
yield
growth
has
been
lower
in
wheat
and
rice
than
in
corn
and
soybeans.
This
isproblematic
because
wheat
and
rice
are
more
important
as
foods,
accounting
for
around
halfof
all
calories
consumed.
Corn
and
soyabeans
are
more
important
as
feed
grains.
The
authorsnote
that
“we
have
preferentially
focused
our
crop
improvement
efforts
on
feeding
animals
andcars
rather
than
on
crops
that
feed
people
and
are
the
basis
of
food
security
in
much
of
theworld.”The
report
qualifies
the
more
optimistic
findings
of
another
new
paper
which
suggests
that
theworld
will
not
have
to
dig
up
a
lot
more
land
for
farmin
