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

65.Howshouldwetreatourrivalsafterasuccessfuldebate?

A)Trytomakepeacewiththem.

B)Trytomakeupthedifferences.

C)Invitethemtotheringnexttime.

D)Acknowledgetheircontribution.參照答案：

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“這種舒適會讓你意識不到你可以擴(kuò)大你的企業(yè)和事業(yè)”，對應(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”對應(yīng)“purpose”，背面跟的即為答案：“isnottowinbuttogetthetruththatwillallowyoutomovefaster,farther,andbetter.”，對應(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”對應(yīng)到最終一段的“sparringpartners”，原文給出“讓他們懂得對他們的付出你很感謝”，對應(yīng)D選項(xiàng)“肯定他們的付出”，為同義替代關(guān)系。PassageOne

Passage

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?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
