Here

are

four

people

who

lived

through

failure

before

going

on

to

become

names

known

around

the

world.

Walt

DisneyDisney

began

his

career

by

being

fired

by

a

newspaper

for

not

being

creative

enough.

Later,

his

Mickey

Mouse

cartoons

were

rejected

because

they

were

considered

to

be

"too

scary

for

women".

Also,

The

Three

Little

Pigs

was

turned

down

because

it

only

had

four

characters.

Thankfully,

we

have

the

Disney

Company

today

because

Disney

chose

not

to

listen

to

any

of

his

critics

and

press

forward

towards

his

dreams.

Stephen

KingKing

is

a

best-selling

writer

whose

work

has

been

made

into

several

motion

pictures.

However,

his

first

work

was

rejected

30

times,

which

led

to

King

throwing

it

in

the

trash.

Thankfully,

his

wife

persuaded

him

to

keep

working

at

it,

and

—

from

that

poor

start

—

Carrie

was

born.

Milton

HersheyThe

man

who

blessed

us

with

the

sweet

milk

chocolate

treat

we

all

love

wasn't

a

hit

the

first

time

around.

He

once

worked

for

a

local

candy

factory.

But

when

he

went

out

on

his

own,

he

failed

miserably.

Then

he

returned

to

the

family

farm

and

perfected

the

art

of

making

delicious

milk

chocolate

candy,

which

we

enjoy

today.

Theodor

GeiselThis

author

struggled

to

write

a

novel

that

publishing

companies

would

call

"pure

rubbish"

several

times

—

27

to

be

exact.

The

man

just

wouldn't

quit,

though.

One

fateful

night,

he

ran

into

an

old

friend

who

was

a

children's

literature

editor.

The

friend

agreed

to

publish

Geisel's

work.

Better

known

today

as

Dr.

Seuss,

Geisel

never

perseverance

required

to

done

under

conditions

needs

no

explanation.The

busiest

time

for

Tsering

Chopa

is

between

July

and

August

each

year,

when

students

are

waiting

for

their

admission

letters

from

various

universities.

He

recalls

once

he

had

to

deliver

mail

to

one

student

whose

family

had

already

moved

away.

He

had

to

quiz

neighbors

several

times

to

find

the

new

address.

It

was

summer

and

the

usual

road

to

the

village

was

blocked

because

of

rain.

He

trekked

for

more

than

20

km

and

managed

to

cope

with

shortness

of

breath

all

the

way

to

finally

deliver

the

letter.

"I

don't

mind

the

hardship

because

it

is

not

easy

for

students

from

remote

villages

to

get

college

admissions.

It

is

my

duty

to

deliver

the

mail

on

time,"

he

says.One

night

in

February

2019,

a

local

resident

Nyima

Tsering's

daughter

fainted（晕倒）

and

desperately

needed

help.

Knowing

that,

the

mailman

arranged

for

a

car

right

away

and

sent

her

to

the

county

hospital.

He

also

gave

some

cash

to

the

family

for

the

girl's

treatment.

Nyima

Tsering's

daughter

recovered

soon,

and

Tsering

Chopa

became

an

idol

in

the

village.

"I

will

never

forget

his

kindness,"

says

the

grateful

father.

In

2019,

Tsering

Chopa

received

the

China

Youth

May

Fourth

Medal.

"It

is

an

acknowledgement

of

what

I

do

and

a

token

of

encouragement

as

well,"

he

says.

"And

I

want

to

help

more

people

living

in

remote

areas.

I

want

to

bring

the

world

closer

to

them

and

take

them

[2024山西运城市康杰中学期末考试]There

has

been

a

bitter

argument

within

the

Australian

community

over

a

horse

racing

event

advertised

on

the

Sydney

Opera

House.

While

some

believe

the

Opera

House

is

Australia's

"biggest

billboard（大幅广告牌）"

and

should

be

used

for

economic

gain,

others

are

shocked

that

the

government

has

allowed

the

national

landmark

to

be

polluted

with

branding.

As

a

UNESCO

World

Heritage

Site,

the

Sydney

Opera

House

is

an

important

Australian

building

recognized

all

over

the

world

and

one

of

the

country's

most

frequently

visited

tourist

attractions.

In

the

past,

the

Opera

House

has

been

used

to

promote

a

handful

of

charities,

cultural

festivals,

etc.

However,

these

have

aimed

to

highlight

events

that

bring

advantage

to

ordinary

people,

not

a

single

for-profit

brand.

Some

have

argued

that

promoting

brands

on

the

sails

of

the

Opera

House

is

just

like

advertising

on

any

other

billboard

with

the

power

to

significantly

encourage

tourism

and

economic

growth.

While

this

may

be

true,

if

advertising

continues

to

happen,

the

Opera

House

could

risk

losing

its

reputation,

which

could

devalue（贬低）

the

landmark

and

actually

damage

its

tourism

appeal.

Although

landmarks

around

the

world

such

as

the

Eiffel

Tower

and

Moscow's

Red

Square

have

been

used

for

advertising,

they

have

also

caused

some

arguments

among

the

public.

For

instance,

a

major

fashion

brand

placed

a

giant

branded

suitcase

in

the

center

of

Moscow's

Red

Square;

however,

it

was

removed

shortly

afterwards

as

tourists

complained

it

was

so

big

that

it

blocked

views

of

major

landmark

sites.

The

advertisement

has

caused

arguments

among

the

public

and

finally

failed

to

leave

a

positive

impact.

So

what

will

advertising

on

the

Opera

House

look

like

to

international

tourists?

Will

they

be

amazed

and

drawn

to

a

wonderful

country,

or

will

they

see

advertising

as

something

reducing

the

cultural

value

of

a

national

symbol?

We

think

it's

clear

that

our

national

treasures

deserve

the

respect

and

admiration

that

come

with

them,

and

that

advertising

should

be

limited

to

important

causes,

not

campaigns

for

commercial

gain.【解题导语】

考查细节理解。根据第一段中的"There

has

been

a

bitter

argument...advertised

on

the

Sydney

Opera

House"可知，是悉尼歌剧院登的赛马活动的广告引起了澳大利亚人的激烈争论。故选B项。29.What

考查推理判断。根据第二段后两句可知，在过去，悉尼歌剧院曾被用来宣传少数慈善机构、文化节等。这些活动旨在强调为普通人带来好处，而不是为了突出某个营利性品牌。由此可推知，之前在悉尼歌剧院宣传的活动都是为了公众的利益。故选A项。be

考查推理判断。第三段最后一句提及，如果广告活动继续进行，悉尼歌剧院可能会失去声誉，这可能会降低这座地标性建筑的价值，并危害其旅游吸引力；再结合第四段中的"The

advertisement

has

caused

arguments

among

the

public

and

finally

failed

to

leave

a

positive

impact"可知，作者举莫斯科红场的例子是为了说明将地标用于商业宣传，最终会带来负面影响。故选D项。31.What

attitude

toward

the

commercial

act

mentioned

at

the

beginning?(

)

CA.Favourable.

B.Doubtful.

C.Opposed.

D.Objective.【解析】

考查观点态度。根据最后一段最后一句可知，作者认为，我们的国宝值得尊敬和钦佩，利用其做广告应该仅限于重要的事业，而不是为了商业利益。由此可推知，作者对文章开头提到的商业行为（即在悉尼歌剧院进行商业活动宣传）持反对意见。故选C项。favourable"赞同的"；doubtful"怀疑的"；opposed"反对的"；objective"客观的"。D（科技创新│新高考4年3考）[2024山西太原五中期末考试]Soda

bottles

and

sour

cream

containers

—

these

plastics

（and

many

others）

typically

arrive

at

recycling

plants

mixed

together

in

the

same

bin.

But

since

they

are

made

of

different

molecular（分子的）

building

blocks,

called

monomers,

they

must

be

sorted

into

different

types

before

they

can

be

melted

to

make

new

products.

Otherwise,

their

various

monomers

tend

to

separate

from

one

another

like

oil

and

water.

"Until

about

a

year

ago,

everybody

thought

the

only

thing

you

could

do

was

take

a

plastic,

break

it

down

to

a

monomer

and

then

re-form

it,"

says

Sanat

Kumar,

a

chemical

engineer

at

Columbia

University."Now

we've

come

up

with

a

different

way

of

doing

it."

His

team

has

developed

a

process

that

allows

different

kinds

of

plastics

to

be

recycled

together.

Their

findings,

reported

recently

in

Nature,

could

give

new

life

to

many

items

that

end

up

in

landfills.

The

new

process

solves

the

problem

by

adding

chemicals

called

universal

dynamic

cross-linkers

to

the

mix.

Just

as

soap

brings

together

oil

and

water,

these

cross-linkers

form

covalent（共价的）

molecular

bonds

that

tie

the

diverse

monomers

together.

This

process

creates

materials

that

can

keep

certain

useful

properties

of

each

plastic,

such

as

keeping

oxygen

from

passing

through.

These

materials

can

then

be

melted

and

remade

again

and

again

because

the

cross-linkers

can

break

and

re-form

their

bonds.

The

researchers

hope

the

technique

could

eventually

help

repurpose（改变……的用途）

more

plastic

waste,

and

Kumar

says

the

process

consumes

less

energy

than

breaking

plastics

down

into

their

original

monomers

—

but

it's

not

yet

cheap

enough

to

be

widely

used

at

existing

recycling

facilities.

Still,

showing

that

it

works

could

lead

to

profitable

markets

for

less

expensive

recycled

plastics,

which

Kumar

says

would

be

one

way

to

help

recyclers

eventually

address

the

plastic

waste

crisis."The

plastic

problem

is

huge,"

he

says,

"and

you're

going

to

have

to

look

for

multiple

solutions."【解题导语】哥伦比亚大学的化学工程师Sanat
