Elephants’ important role in maintaining biodiversity and healthy ecosystems has earned them various names including ecosystem engineers and forest gardeners.However，African forest elephants—a species living in the rainforests of central Africa—are increasingly recognized by another name: “climate heroes”.
语篇解读　本文是一篇说明文。文章主要介绍了非洲森林象因有助于提升森林的碳捕获能力从而减缓气候变化而被称作“气候英雄”，以及它们面临的威胁。
Ⅲ.主题语篇阅读
African forest elephants help lessen climate change by increasing carbon storage in their forest habitats，meaning they help remove heat-trapping CO2 from the atmosphere.They do this by influencing the forest structure，including by increasing the diversity and abundance of plant species.It’s estimated that one forest elephant can increase the net carbon capture(捕获) capacity of the forest by almost 250 acres.This is equal to removing from the atmosphere a year’s worth of emissions(排放量) from 2,047 cars.
“As strange as it seems，all that eating and destruction help the forest pull more carbon out of the air，” says Alison Pearce Stevens in the book Animal Climate Heroes！.Elephants eat more than 400 pounds of food a day，so they spend a lot of time searching for food.As they walk through the forest，they do a lot of damage to the surrounding smaller trees，leading to the survival of trees that have the ability to absorb and store more CO2.
In addition，their thirst for fruits also helps to promote forest growth.This is because elephants disperse fruit seeds.In other words，the seeds pass through the elephant bodies until they drop back to the forest floor.
But African forest elephants are seriously endangered and continue to face threats.These mainly come from hunting for the illegal international trade in elephant ivory(象牙)，but also from habitat loss and fewer food sources.The number of forest elephants fell by more than 86% over a period of 31 years，and their habitats are thought to have reduced by 75%.Protecting forest elephants and the forests they depend on means we are safeguarding their ecological contributions that we all rely on.
1.How do African forest elephants help relieve climate change
A.They increase the diversity of wildlife species.
B.They help to maintain the plants of the forest.
C.They take in heat-trapping CO2 from the atmosphere.
D.They promote the net carbon capture ability of the forest.
√
细节理解题。根据第二段中“African forest elephants help lessen climate change by increasing carbon storage in their forest habitats”和“It’s estimated that one forest elephant can increase the net carbon capture(捕获) capacity of the forest by almost 250 acres.”可知，非洲森林象通过提高森林的碳捕获能力来帮助减缓气候变化。故选D。
解析
2.What does the underlined word “disperse” in paragraph 4 mean
A.Consume. B.Preserve.
C.Spread. D.Gather.
√
词义猜测题。根据画线词下文“In other words，the seeds pass through the elephant bodies until they drop back to the forest floor.”可知，水果的种子通过大象的排泄从大象体内回到森林地面，这帮助散播了水果种子，有助于促进森林的生长。故disperse 同spread“传播”意思相近。故选C。
解析
3.What are the threats faced by African forest elephants
A.Illegal hunting and habitat loss.
B.The disturbed balance of the forest ecosystem.
C.Natural disasters resulting from climate change.
D.Competition for water sources with other animals.
细节理解题。根据最后一段中“These mainly come from hunting for the illegal international trade in elephant ivory(象牙)，but also from habitat loss and fewer food sources.”可知，非洲森林象面临的主要威胁是非法狩猎、栖息地丧失和食物来源减少。故选A。
解析
√
4.What can be a suitable title for the text
A.Preserving Forests: Elephants’ Contribution
B.New Role of African Forest Elephants: Climate Heroes
C.Ivory Trade Threatens African Forest Elephants
D.Forest Elephants Are Approaching the Edge of Extinction
√
标题归纳题。通读全文，尤其是根据第一段可知，本文主要讲述了非洲森林象因有助于提升森林的碳捕获能力来缓解气候变化而被称作“气候英雄”，以及它们所面临的威胁；因此，B选项“非洲森林象的新角色：气候英雄”适合作为本文的标题，故选B。
解析
B(此篇精读)
Every year，as many as 3,000 dogs from all over the world gather in New York City to compete in the famous Westminster Kennel Club Dog Show that lasts three or four days.Established in 1877，it’s the oldest show of its kind.It’s also one of the biggest，drawing crowds of① dog lovers.Behind the scenes，Paul Campanella manages the whole operation.
语篇解读　本文是一篇记叙文。文章主要讲述了WKC犬展运营总监Paul Campanella将童年对狗的热爱转化为职业动力的故事。
Campanella is senior director of event operations for the Westminster Kennel Club(WKC).In 2025，show events were held at Madison Square Garden and the Jacob Javits Convention Center，both in New York City.Campanella’s team worked with the venues(活动的场所) to determine everything from lights to decorations to floral(花卉) arrangements，while working closely with the television networks that broadcast the show.The competition takes place once a year.Planning for the following year begins the moment the show ends.One of Campanella’s biggest responsibilities is handling the budget(预算).Since the WKC is a non-profit② organization，it’s important to stick to a budget.
Campanella started working for the WKC on a part-time basis as head of security in 2001.At the time，he worked for the New York City Police Department.When he retired in 2013，the WKC hired him full-time.His job was to create two new events for the annual show.For Campanella，this was more than a career move.It was a dream opportunity.He’s loved dogs and dog shows since he was 12，when his parents gave him a dog named Starr.Today，he serves as a judge for other events and also shows his dog，Nigel.
Although Campanella majored in criminal(刑事的)justice as a college student，he believes a business degree is the best foundation for a career in event operations.Success in the field also requires specific skills.“You have to be very organized and be able to organize other people，” Campanella says.He also notes③ it’s important to know how to “work with numbers” to discuss contracts(合同) with the different companies hired for the event.
5.What can we learn about the Westminster Kennel Club Dog Show
A.It belongs to Campanella.
B.It is held annually.
C.It lasts over a week.
D.It is a local event.
细节理解题。根据第一段中“Every year，as many as 3,000 dogs...lasts three or four days.”以及第二段中“The competition takes place once a year.”可知，该犬展每年举办一次。故选B。
解析
√
6.Which best describes Campanella’s 2025 event operations
A.They were flexible.
B.They were cost-ineffective.
C.They required careful planning.
D.They lacked local support.
√
推理判断题。根据第二段中“Campanella’s team worked with the venues(活动的场所) to determine everything...it’s important to stick to a budget.”可知，Campanella的团队需要确定从灯光到装饰到花卉安排的一切，同时与转播这场演出的电视网络密切合作，此外在演出结束的那一刻就要开始计划下一年的演出，Campanella最大的职责就是处理预算，因此可推知活动运营需要周密计划。故选C。
解析
7.What was Campanella’s childhood dream
A.Attending dog shows.
B.Becoming a policeman.
C.Learning criminal justice.
D.Judging animal contests.
细节理解题。根据第三段中“For Campanella，this was more than a career move.It was a dream opportunity.He’s loved dogs and dog shows since he was 12，when his parents gave him a dog named Starr.”可知，Campanella的童年梦想是参与犬展。故选A。
解析
√
8.What does the text focus on concerning Campanella
A.His love for animals.
B.His job responsibilities.
C.His charity events.
D.His unique personality.
推理判断题。根据全文尤其第二段可知，文章介绍了Campanella的职责(统筹灯光、装饰、花卉和电视网络等各方面活动、管理预算、创设下一年演出新活动等)及职业历程。由此推知，文章重点介绍了他的工作职责。故选B。

Saving Seeds for Next Year’s Flower Garden
Just like vegetable seeds，you can save flower seeds from your garden this year to plant in the following year.
语篇解读　这是一篇说明文。文章主要介绍了为来年的花园保存种子的方法。
Ⅳ.七选五阅读
If you want the same kind of flower or plant for next year’s garden，collect only the seeds from plants marked as “heritage”. 1 Hybrid(杂交的) seeds with a mixture of two different parents will produce new plants，but they will only look like one of the parents.Therefore，you are taking a risk with planting hybrid seeds.

Elephants’ important role in maintaining biodiversity and healthy ecosystems has earned them various names including ecosystem engineers and forest gardeners.However，African forest elephants—a species living in the rainforests of central Africa—are increasingly recognized by another name: “climate heroes”．
African forest elephants help lessen climate change by increasing carbon storage in their forest habitats，meaning they help remove heat-trapping CO2 from the atmosphere.They do this by influencing the forest structure，including by increasing the diversity and abundance of plant species.It’s estimated that one forest elephant can increase the net carbon capture(捕获) capacity of the forest by almost 250 acres.This is equal to removing from the atmosphere a year’s worth of emissions(排放量) from 2,047 cars.
“As strange as it seems，all that eating and destruction help the forest pull more carbon out of the air，” says Alison Pearce Stevens in the book Animal Climate Heroes！.Elephants eat more than 400 pounds of food a day，so they spend a lot of time searching for food.As they walk through the forest，they do a lot of damage to the surrounding smaller trees，leading to the survival of trees that have the ability to absorb and store more CO2.
In addition，their thirst for fruits also helps to promote forest growth.This is because elephants disperse fruit seeds.In other words，the seeds pass through the elephant bodies until they drop back to the forest floor.
But African forest elephants are seriously endangered and continue to face threats.These mainly come from hunting for the illegal international trade in elephant ivory(象牙)，but also from habitat loss and fewer food sources.The number of forest elephants fell by more than 86% over a period of 31 years，and their habitats are thought to have reduced by 75%.Protecting forest elephants and the forests they depend on means we are safeguarding their ecological contributions that we all rely on.

Every year，as many as 3,000 dogs from all over the world gather in New York City to compete in the famous Westminster Kennel Club Dog Show that lasts three or four days.Established in 1877，it’s the oldest show of its kind.It’s also one of the biggest，drawing crowds of① dog lovers.Behind the scenes，Paul Campanella manages the whole operation.
Campanella is senior director of event operations for the Westminster Kennel Club(WKC)．In 2025，show events were held at Madison Square Garden and the Jacob Javits Convention Center，both in New York City.Campanella’s team worked with the venues(活动的场所) to determine everything from lights to decorations to floral(花卉) arrangements，while working closely with the television networks that broadcast the show.The competition takes place once a year.Planning for the following year begins the moment the show ends.One of Campanella’s biggest responsibilities is handling the budget(预算)．Since the WKC is a non-profit② organization，it’s important to stick to a budget.
Campanella started working for the WKC on a part-time basis as head of security in 2001.At the time，he worked for the New York City Police Department.When he retired in 2013，the WKC hired him full-time.His job was to create two new events for the annual show.For Campanella，this was more than a career move.It was a dream opportunity.He’s loved dogs and dog shows since he was 12，when his parents gave him a dog named Starr.Today，he serves as a judge for other events and also shows his dog，Nigel.
Although Campanella majored in criminal(刑事的)justice as a college student，he believes a business degree is the best foundation for a career in event operations.Success in the field also requires specific skills.“You have to be very organized and be able to organize other people，” Campanella says.He also notes③ it’s important to know how to “work with numbers” to discuss contracts(合同) with the different companies hired for the event.

[语境猜词]
①crowds of成群的
②non-profit(派)＝non＋profit adj.非营利的；不以营利为目的的
③note 熟义：n.笔记 生义(文义)：v.指出；特别提到
[句式分析]
Campanella’s team worked with the venues to determine everything from lights to decorations to floral arrangements，while working closely with the television networks that broadcast the show.
分析：此句为复合句。“to determine everything”为动词不定式作目的状语；“from lights to decorations to floral arrangements”为介词短语作后置定语，修饰everything；“while working closely with the television networks”为while引导的时间状语从句的省略，省略了Campanella’s team were；“that broadcast the show”为定语从句，修饰the television networks。
翻译：Campanella的团队与活动场馆合作，决定从灯光到装饰到花卉安排的一切，同时还与转播这场演出的电视网络密切合作。
Ⅳ.七选五阅读(共5小题；每小题2.5分，满分12.5分)
Saving Seeds for Next Year’s Flower Garden
Just like vegetable seeds，you can save flower seeds from your garden this year to plant in the following year.
If you want the same kind of flower or plant for next year’s garden，collect only the seeds from plants marked as “heritage”． 1 Hybrid(杂交的) seeds with a mixture of two different parents will produce new plants，but they will only look like one of the parents.Therefore，you are taking a risk with planting hybrid seeds.
2 Wind or insects could bring pollen from one plant to another and accidentally create a mixture.You can avoid this by planting only the plant from which you plan to collect seeds.But if you like surprises，start experimenting! You could create a lovely new plant or flower!
Just like everything else in gardening，timing is important.Collect seeds on a dry，sunny day.Let the seeds grow and fall naturally.When their pods(荚) open，these plants could send their seeds up to 6 meters away.Once on the ground，it is difficult to collect them. 3
For plants like sunflowers，cut the head off the plant and drop it into a paper bag. 4 This will save your fingers!
You can place the seeds in a glass box that can be sealed(封上)．Then store them in a cool，dry area.Make sure to mark your glass box so you do not forget what they are. 5 But you should plant the new seeds the following year for best results.
A．Keep an eye on some flowers.
B．Give the bag a shake to help separate the seeds.
C．When stored with care，seeds are good for several years.
D．These kinds of plants will grow just like their parent plant.
E．In this case，add more seeds to the soil to make sure that some will grow.
F．Even if you expect plants to be the same as their parents，it is not certain.
G．Instead，tie a small bag for seed collection over the pod when it nearly opens.
