(2026·深圳l·二模)This summer I came face-to-face with three deep-rooted fears::heights,bears,and ageing.
Two friends joined me on a four-day wilderness getaway,and since we were all in our seventies,we decided we'd
better go while we still could.Our adventure began with a scary drive up a winding mountain road.
On one hike,I found myself hanging onto a wire on a bridge made of two partly rotten (logs,suspended
high above rushing rapids.I would never have attempted it without our guide ahead,mouthing encouraging words.
Fixing my eyes on her boots,I inched along the shaky logs.Somehow,I made it across,flooded with a rush of intense
excitement and huge relief.
Later,after spotting bear tracks,we were told to make loud noises,which soon became a game once the tension
faded.
Until suddenly,time stood still.
We had just crossed a stream when the guide whispered,"There's a bear."I looked up in disbelief and saw not one,
but two,about ten meters above us-the brown mother in front,her cub behind.
Though scared speechless,I couldn't help noticing how beautiful they looked in their natural setting.I wondered
if it would be my last memory.As they started towards us,we recovered enough to shout and wave our hiking poles.
Taken aback,they stopped,and then slowly turned away.Another fear was overcome!
On our final morning,after a quiet,thoughtful walk through the forest,we were asked to bring back a"meaningful"
stick,rock,and leaf to share what would“stick”with us,.what“rocked,.”and what we would“leaf'behind.The bond of
friendship would stick with me.Women supporting one another truly rocked.And I hoped to leave some fears behind.
Our guide ended by expressing her admiration,praising not only our fitness but also our positive attitude,and
saying she hoped to be like us in another thirty or forty years.Those unexpected words warmed my heart and eased my
fear of being "over the hill."Being valued for what we had accomplished felt like winning an Olympic medal-even if

(2026温州·二模)The room looks like your typical office:white walls,low ceilings,gray carpet worn thin from
years of foot traffic.But for this vacant office outside Dupont Circle in Washington,D.C.,real estate
developers see potential.
Cities across the U.S.are struggling with two problems:too much empty office space and not enough housing.
Nationally,office vacancy rates reached roughly 20%in 2024,after years of employees working from home.At the same
time,the national housing shortage is in the millions.Cities like D.C.,are now betting that by turning empty offices into
homes,one crisis can help solve the other.
A project in D.C.,which broke ground last month,is the largest such conversion (in the city to date.The
overall structure of the buildings will remain the same,but with major additions:a lighter-colored exterior will replace
the gray concrete from the 1960s,and old inefficient windows will be replaced by larger ones that let in more light per
unit.Plans include luxuries such as a pool and a dog park,with projected rent around S4,000 per month.Yet 60 units will
be set aside as affordable housing."We would love to do more,"says Matt Pestronk,the president of a development
company,"but unfortunately,almost all capital seeks a return.This was as much as we could afford to do."
"The scale of the shortage far outpaces what conversions can provide."says Tracy Loh,a fellow at the Brookings
Institution who studies adaptive reuse of old buildings.But she argues that these projects still matter,"It does kill two
birds with one stone,in terms of providing some housing supply."And it tends to create housing in central,
transit-accessible areas that are in high demand.
The decline of manufacturing (in the late 20th century offers a glimpse of what comes next.When shifts
happen in the economy and society,the built environment must change to match contemporary demand.Just as empty
factory floors became trendy apartments,today's empty office spaces are turning into stylish kitchens and bedrooms.
8.What are cities like DC trying to do?
A.Repurpose empty offices.
B.Tear down unused buildings.
C.Build housing in suburbs.
D.Encourage working from home
9.What can be inferred about the project in paragraph 3?
A.It requires structural changes.
B.It targets low-income families.
C.It is funded by the government.
D.It balances profit and social needs.
10.What does Tracy Loh think of the conversion?
A.Realistic.
B.Far-reaching.
C.Demanding.
D.Short-sighted.
11.What can be a suitable title for the text?
A.Cities Are Caught in Crisis
B.Housing Demand Is Crying for More
C.Offices Are Becoming Homes
D.Manufacturing Is Gaining a Second Life
(2026·厦门·二模)Power bills are going up in America and people are angry.They know whom to blame一the
bosses of technology firms thirsting for more juice to fuel artificial-intelligence data centres.However,the AI boom is
not chiefly to blame for the rising costs.
Electricity prices have risen faster than inflation (in recent years (see chart).Data centres are indeed
consuming more power than before and,as Goldman Sachs,a bank,holds,will account for nearly half of the overall
demand growth in America in the coming years.Yet even business forecasts put data centres'share of total demand at

A study conducted last year showed that data-centre load was not the main cause of the rate rises in the five years
to 2024.It fingered grid upgrades and rising costs of power-generating equipment and raw materials.It is
estimated that last year demand for distribution transformers outran supply by 10%.There are also long waiting lists for
essential grid-related equipment.
Many prices started going up in early 2021,nearly two years before the rapid growth AI.They are likely to keep
rising for non-AI reasons.The Edison Electric Institute,which represents private-sector power companies,predicts its
members'total capital spending will reach S1.Itrn between 2025 and 2029.More than half the sum for distribution and
transmission infrastructure (will go on replacing ageing equipment and hardening it against extreme weather
made likelier by climate change.These factors have been ignored for years.Now AI provides an excuse to help win
approval from regulators to pass the cost on to consumers.
Al may even be lowering prices.The tech giants are already investing in their own capacity.Microsoft has signed
a long-term deal to restart a nuclear reactor at Three Mile Island to supply its data centres.Meta has backed a handful of
nuclear startups.The World Resources Institute,another think-tank,notes that in North Dakota rising demand from oil
and gas production,data-centre operators and food-processors led to large price reductions for local electricity users.
Definitely,if Americans want lower electricity bills,they should be shouting for more Al,not less.
12.Why does the author mention public anger in paragraph 1?
A.To highlight a social conflict.

13.What have mainly contributed to the rising electricity prices in paragraphs 3&4?
A.AI Growth and data demand.
B.Big Tech and market shares.
C.Grid upgrades and facility costs.
D.Climate change and capital spending.
14.How does the author develop the last paragraph?
A.By making a contrast.
B.By providing examples.
C.By describing a study.
D.By drawing conclusions.
15.Which can be a suitable title for the text?
A.Hidden Costs:The Impact of Rapid AI Development
B.Going Nuclear:A Potential Solution to Power Shortage
C.Energy Reform:How to Reduce Monthly Electricity Bills
D.Beyond AI:Uncovering the Real Drivers of Rising Power Costs

health issues or financial pressure.You may enter distant places at any moment and leave just as freely.For those
restricted by schedule,health,or income,VR quietly removes barriers that traditional travel often sets in place.
18Travelers wander through unfamiliar streets,sample local dishes,and engage face-to-face with people
shaped by different traditions.Such encounters awaken the senses and create lasting memories.More importantly,they
change how places feel to us,not just how we understand them.
This distinction is clear,because learning about a destination is not the same as being there.Virtual travel offers
designed scenes and programmed sensations,but it remains carefully controlled.Real travel,by contrast,is shaped by
unpredictability.19 In those unplanned moments,understanding becomes lived rather than recorded.
Virtual reality will undoubtedly continue to evolve,enriching how we preview journeys and imagine distant
worlds.Still,it cannot replace actual presence.Travel is not simply about seeing farther;it is also about feeling where
you stand.20
