一、阅读理解
Passage A
For decades,scientists believed that trees in a forest were solitary creatures,competing with each other for
sunlight and nutrients.This view has been dramatically overturned by the research of forest ecologist Dr.
Suzanne Simard,who discovered that trees are far more social and cooperative than previously imagined.
What she found was a complex underground network that connects trees,allowing them to communicate,
share resources,and even warn each other of danger.
At the heart of this network lies the mycorhizal fungi,microscopic organisms that form symbiotic
relationships with tree roots.These fungi act as the intemet cables of the forest,transmitting chemical
signals from one tree to another.Through this web,older trees known as"mother trees"can send carbon,
nitrogen,and water to younger seedlings struggling in the shade.In one remarkable experiment,Simard
showed that a birch tree,when injected with radioactive carbon,transferred the carbon to a nearby fir tree
that was being shaded.The fir tree,in tumn,later retumned the favor when the birch was leafless in winter.
The implications of this discovery are profound.When a tree is attacked by insects,it releases chemical
distress signals through the fungal network,warning neighboring trees to boost their chemical defenses.
This early warning system can save entire groves from devastation.Furthermore,the network allows trees
to recognize their own offspring-mother trees favor their kin by sending them more nutrients through
the fungal connections.
This understanding challenges our conventional notions of competition and survival in nature.Rather
than viewing forests as collections of individuals fighting for survival,Simard suggests we should see
them as superorganisms,where the health of each individual is tied to the health of the whole.When we
cut down a mother tree,we not only lose that individual but potentially damage the entire network that
has been nurturing the next generation.
The research has significant implications for forestry practices.Clear-cutting,a common logging method
that removes all trees from an area,disrupts this fungal network entirely.Simard advocates for selective
logging that preserves mother trees and maintains the integrity of the underground communication system
She argues that by treating forests as communities rather than timber factories,we can develop more
sustainable approaches to foresty that protect both the ecosystem and our long-term interests.

A.enemies
B.competitors
C.family members
D.parasites
()5.What is the author's attitude toward clear-cutting?
A.Strongly supportive
B.Cautiously optimistic
C.Generally critical
D.Completely indifferent
Passage B
As urbanization accelerates globally,with more than half of the world's population now living in cities,
the importance of green spaces within urban environments has become a subject of intense scientific
investigation.Parks,community gardens,tree-lined streets,and even small patches of vegetation are
proving to be far more than aesthetic enhancements-they are essential components of public health
infrastructure
A landmark study conducted by researchers at the University of Exeter Medical School analyzed data
from over 10,000 urban dwellers over a period of 18 years.The findings were striking:individuals living
in neighborhoods with more green space reported significantly lower levels of mental distress and higher
life satisfaction.What made this study particularly compelling was that the positive effects were observed
regardless of income level,suggesting that access to nature benefits everyone,not just those who can
afford homes in affluent green suburbs.
The mechanisms behind these benefits are multifaceted.Exposure to natural environments has been
shown to reduce cortisol levels,the hormone associated with stress.Even brief encounters with green
spaces-as short as five minutes-can lower blood pressure and improve mood.Additionally,natural
settings promote what psychologists call"soft fascination,"a gentle form of attention that allows the
brain's directed attention system to rest and recover.This is particularly important in urban environments,
where the constant demands of traffic,advertising,and digital screens can lead to mental fatigue.
Beyond individual well-being,green spaces foster community cohesion.Parks and gardens provide
venues for social interaction,where neighbors can meet,children can play,and community events can
take place.Research from the University of Illinois found that residents living near green spaces reported
stronger social ties and a greater sense of belonging to their community.In neighborhoods with well-
maintained green areas,residents were more likely to know their neighbors and to help each other in
times ofneed.
The COVID-19 pandemic underscored the critical role of urban nature.During lockdowns,parks became
vital sanctuaries for physical exercise,mental respite,and safe social contact.Cities that had invested in
accessible green spaces saw their residents cope better with the stresses of isolation and uncertainty.This
has led urban planners to reconsider the design of cities,with many now advocating for the"15-minute
city"concept,where every resident can access a park within a 15-minute walk from home.
However,disparities in access to green spaces remain a pressing concern.Low-income neighborhoods
and communities of color often have fewer parks and trees,a phenomenon described as "green
gentification."Addressing these inequities is not merely a matter of environmental justice but a public
health imperative.As cities continue to grow,ensuring equitable access to nature will be one of the
defining challenges of urban planning in the 21st century.
()1.What does the University of Exeter study primarily demonstrate?
A.Wealthy people benefit more from green spaces.
B.Green spaces improve mental health across all income levels.
C.Urban dwellers rarely use parks for recreation.
D.Income determines access to natural environments.
()2.According to paragraph 3,what is "soft fascination?
A.A state of intense concentration
B.A way to recover mental energy
C.A negative response to nature
D.A type of physical exercise
()3.How do green spaces contribute to community cohesion?
A.By increasing property values
B.By providing opportunities for social interaction
C.By reducing the need for public services
D.By attracting tourists to the area
()4.What does the "15-minute city"concept refer to?
A.A city where all services are within 15 minutes
B.A city that limits car use to 15 minutes daily
C.A city with parks within 15 minutes walk for residents
D.A city designed for 15-minute work commutes
()5.What challenge does the passage identify regarding urban green spaces?
A.Maintaining parks is too expensive.
B.Access to green spaces is unevenly distributed.
C.Parks attract too many visitors.
D.Green spaces reduce housing availability.

In 2015,a young woman named Wangari Maathai was making her way through the dusty streets of
Nairobi,Kenya.She had just completed her studies abroad and retumed home with a vision that would
(1)
transform her country's landscape.What she saw distressed her deeply:the once lush
hillsides had been stripped bare,their forests(2)
for fuel and farmland.Rivers that had flowed
for centuries were diying up,and the soil was being carried away by the wind.
Maathai's plan was simple but (3):she would plant trees.Not just a few trees,but millions of

三、阅读短文回答问题
Read the following passage and answer the questions in complete sentences.
When we think of plastic pollution,images of floating garbage patches in the ocean or plastic bags caught
in tree branches often come to mind.However,a growing body ofresearch reveals a more insidious form
of plastic contamination that is hidden beneath our feet-microplastics in the soil.
Microplastics,defined as plastic fragments smaller than five millimeters,have infiltrated agricultural soils
across the globe at alarming rates.Scientists estimate that the amount of microplastics in terrestrial
environments may be four to twenty-three times greater than that in the oceans.This finding is particularly
concemning because soil forms the foundation of our food system.
The primary source of soil microplastics is sewage sludge,which is commonly used as fertilizer in
agriculture.When we wash synthetic clothing,tiny plastic fibers are released and eventually end up in
wastewater treatment plants.These facilities are not designed to capture such small particles,so the
plastics accumulate in the sludge,which is then spread onto farmland.Additionally,plastic mulching films
used to retain soil moisture and control weeds degrade over time,breaking down into smaller particles
that become incorporated into the soil.
The consequences for soil health are potentially severe.Microplastics can alter soil structure,reducing its
ability to hold water and nutrients.They can also disrupt the activity ofearthworms and other soil
organisms that are essential for maintaining healthy soil.Larger plastic particles can create pathways for
water to flow too quickly through the soil,canying away nutrients.Even more conceming is the ability of
microplastics to absorb and transport toxic chemicals,potentially introducing harmful substances into the
food chain
Recent studies have detected microplastics in a wide range of food products,including honey,sugar,beer,
and even tap water.While the health implications of ingesting microplastics are not yet fully understood,
early research suggests potential risks,including inflammation,oxidative stress,and the transfer of
chemical additives to human tissues.
Addressing this issue requires action at multiple levels.Individual consumers can reduce their contribution
by choosing natural fibers over synthetics and minimizing the use of plastic in daily life.On a larger scale,
wastewater treatment technologies need to be upgraded to capture microplastic particles.Agricultural
practices must evolve to reduce reliance on plastic mulches and sewage sludge.Policy makers are
beginning to take notice,with the European Union recently proposing limits on microplastic pollution as
part of its broader environmental strategy.
Perhaps the most challenging aspect of this problem is its invisibility.Unlike the plastic bottles floating on
ocean surfaces,microplastics in soil cannot be seen or cleaned up easily.Once they enter the soil,they
persist for centuries,slowly accumulating and potentially affecting ecosystems in ways we are only
beginning to understand.The plastic beneath our feet may tumn out to be one of the most lasting legacies
of our disposable culture.
1.According to the passage,what makes microplastic pollution in soil particularly different from visible
plastic pollution?
2.What are the two main sources of microplastics in agricultural soil mentioned in the passage?
3.How do microplastics affect the ability of soil to support plant growth?
4.Why are the health risks of ingesting microplastics considered"not yet fully understood'?
5.What makes the problem of soil microplastics particularly difficult to solve?

The Nature Around Me
Behind my apartment building lies a small patch of woodland that has become my sanctuary.Every
morning,I walk through the narrow path lined with ancient oak trees,their branches forming a natural
canopy that filters the golden sunlight.The air smells of damp earth and wild mint,and I can hear the
gentle rustling ofleaves and the cheerful songs of hidden birds.
This small woodland has taught me to slow down.In the rush of exams and homework,it reminds me
that life moves at its own pace-the trees grow slowly,the seasons change unhuriedly,and the stream
flows steadily.It has become my place of peace,where I can clear my mind and find perspective.
But this precious piece of nature is fragile.I have seen trash left behind by careless visitors and trees
damaged by thoughtless acts.We must cherish these natural spaces before they disappear.Every small
action counts-picking up litter,planting a tree,or simply respecting the silence of the forest.Let us
protect the nature around us,for it nurtures not only our environment but also our souls.
