(2025·太原高三年级模拟考试)Many peple encurage cmpetitin and fcus n success.“ Giving up” is frwned upn.We are verjyed at stries f peple wh persevered and succeeded.Friends and clleagues always encurage yu t keep trying.“If at first yu dn’t succeed，try，try again.” “Fllw yur dream！ Winners never quit！”
Perseverance is indeed imprtant，t a limit.Hwever，never take it t far.Fr ne thing，gals and dreams might be beynd reach.Stries f achieving childhd dreams thrugh perseverance might be uplifting，but they suffer frm “selectin bias”.Put simply，they are nt infrmative，because nbdy tells stries abut the many peple wh persevered but failed after wasting a gd part f their lives.It is indeed frustrating if yu fllw an unrealistic dream.Fr anther，every rad taken means anther rad is nt taken.An unrealistic gal means missing ut n ther pprtunities.What if everybdy with the childhd dream f becming an astrnaut persistently kept trying frever？ Winners always wisely chse what t quit and what t pursue.
Recent studies have shwn that being able t give up sme gals and dreams and redirect yur energy tward mre reasnable nes is imprtant fr mental well-being and leads t higher quality f life in the lng term.The psychlgical term is “gal disengagement”.If yu are currently devting t much time and effrt t an unattainable gal，here are sme hints that might help.
First，d nt tie a gal t yur identity.Nbdy can be defined by a single gal r interest.Besides，disengage frm a gal but keep sme f the effrt.It’s called “turning it int a hbby”.Few stamp and cin cllectrs desire t becme prfessinals，yet many enjy cllecting.Last and mst imprtant，d nt think f giving up as a failure，but as a chice.Yur time is limited.Try new activities，rediscver previus interests，and revise yur ambitins.Be hnest with yurself abut yur chances，and chse the gals that best suit yu.And remember that，when yu give up a gal，yu d nt fail.Yu make a chice t free up yur time fr ther pssibilities.
[语篇解读]本文是说明文。坚持不懈固然重要，但不能过度，因为有些目标可能遥不可及，坚持不切实际的目标意味着错过其他机会。研究表明，能够放弃一些目标并将精力转向更合理的目标对心理健康和提高生活质量很重要。
1.What result may “selectin bias” bring t peple？
A.Setting self-limitatin.
B.Giving up mre easily.
C.Misjudging the situatin.
D.Ignring successful stries.
C [推理判断题。根据题干中的“selectin bias”将答案定位在第二段。第二段的“Stries f achieving childhd dreams thrugh perseverance might be is indeed frustrating if yu fllw an unrealistic dream”讲通过坚持不懈实现童年梦想的故事可能会令人振奋，但这存在“选择偏倚”；简单来说，这些故事并没有提供有用的信息，因为没人会讲述许多人浪费了生命中相当一部分时间去坚持却最终失败的故事，如果你追随一个不切实际的梦想，那确实会令人沮丧。这意味着“选择偏倚”会让人们只看到成功的故事，从而错误判断形势，认为只要坚持就能成功，故选C。]
2.Hw can peple benefit frm “gal disengagement”？
A.By mtivating their desire fr success.
B.By gaining a sense f self-satisfactin.
C.By telling easy gals frm difficult gals.
D.By saving energy t fcus n practical gals.
D [细节理解题。根据题干中的“gal disengagement”将答案定位在第三段。第三段前两句讲最近的研究表明，能够放弃一些目标和梦想，将精力转向更合理的目标对心理健康很重要，从长远来看会带来更高质量的生活，这在心理学上叫“目标脱离”。所以人们通过节省精力专注实际目标从“目标脱离”中受益，故选D。]
3.Which f the fllwing may the authr agree with？
A.Accepting failure with ease des make sense.
B.One can make a hbby ut f an unattainable gal.
C.Turn t prfessinals when realizing persnal gals.
D.Chsing a gal is mre challenging than realizing it.
B [观点态度题。第四段的“disengage frm a gal but keep sme f the effrt.It’s called ‘turning it int a hbby’”讲从一个目标中脱离出来，但仍保留一些努力，这被称为“把它变成一种爱好”，接着作者以集邮者和钱币收藏者为例来进行说明。所以作者可能同意一个人可以把无法实现的目标变成一种爱好，故选B。]
4.Which f the fllwing is the best title fr the text？
A.Identity Crisis：Be True t Yurself
B.Gals r Hbbies：Make Yur Chice
C.Never Say Never：The Key t Success
D.Winners D Quit：Be Wise Abut Yur Gals
D [主旨大意题。文章开篇提到人们鼓励竞争和坚持，接着指出坚持要有限度，过度坚持不切实际的目标会带来问题，然后说明“目标脱离”的重要性，并给出相关建议。所以文章主要讨论的是要明智地对待目标，懂得放弃不切实际的目标，故D项“成功者会放弃：明智地对待你的目标”最适合作本文标题。]

(2025·武汉高中毕业生四月调研)Heidi Tait，c-funder f Tangara Blue Fundatin，an rganizatin cmmitted t beach cleaning，was puzzled when she and her teammates started finding strange tire-shaped capsules washed ashre alng the Cape Yrk cast，near Australia’s nrtheastern tip.But Tait eventually cnnected with Satlink—a Spanish satellite cmmunicatins cmpany.Satlink’s CPS-enabled buys (浮标)，the nes the beach cleaners kept finding，help cmmercial fishers track their nets，lines etc.Tait had a brainwave that wuld see the buys nt just recycled but reused.
Fr mre than a decade，bat crews wrking farther west，in Australia’s Gulf f Carpentaria，had been telling Tait abut hw abandned fishing nets were circling the gulf，hurting sea creatures.These s-called ghst (幽灵) nets had either brken free frm cmmercial fishing bats and gtten lst，r were cut lse by fishers after getting caught n rcks.Weighing a few tnnes each，the nets that bat crews had chanced upn in the gulf were ften t big fr them t pull ut f the water.They’d typically reprt the finds t the authrities，but by the time anyne with an apprpriately equipped bat culd head ut t get ne，the mass f messy rpe had ften gne frm sight.
Hwever，nce ne f the GPS-enabled buys is attached，it sends its lcatin every few hurs t a website，which lets Tangara Blue Fundatin mnitr the nets’ mvements and warns the rganizatin f danger.S far，the reused GPS trackers have helped Tangara Blue Fundatin recver three ghst nets frm Australian waters.
Tangara Blue Fundatin’s idea t track ghst nets isn’t entirely new； researchers with the Cmmnwealth Scientific and Industrial Research Organisatin (CSIRO)，Australia’s natinal science agency，suggested it a decade ag.Taking the idea n bard，the authrities tried using battery-pwered trackers t mnitr a few ghst nets.Tangara Blue Fundatin’s apprach differs in that its recycled buys are slar-pwered and require less upkeep.
[语篇解读]本文是说明文。Tangara Blue Fundatin组织将原本被冲到岸上的带有全球定位系统功能的浮标回收再利用，用其来追踪幽灵渔网，从而保护海洋生物。
5.What were the tire-shaped capsules riginally used fr？
A.Remving beach waste.
B.Recycling vehicle tires.
C.Lcating fishing equipment.
D.Strengthening satellite signals.
C [细节理解题。文章第一段首句提到Tait和她的队友们在海岸上发现了一些奇怪的、轮胎形状的小塑料容器，接着Tait联系了西班牙卫星通信公司Satlink，得知这些小塑料容器是Satlink的产品，即带有全球定位系统功能的浮标。根据第一段的“Satlink’s GPS-enabled buys(浮标) cmmercial fishers track their nets，lines etc”可知，这些浮标帮助商业渔民追踪他们的渔网、鱼线等设备，故选C。选项中的Lcating对应文中的track，“fishing equipment”对应文中的“their nets，lines etc”。]
6.What des the authr intend t d in Paragraph 2？
A.Illustrate a future pssibility.
B.Describe a technical prcess.
C.Present a practical slutin.
D.Frame a prblem cntext.
D [推理判断题。第二段主要讲在澳大利亚的卡奔塔利亚湾，废弃的渔网，即幽灵渔网，在海湾中转圈，伤害海洋生物，而且这些渔网太大以至于船员们无法将其从水中拉出，在报告给官方后，等有人带着合适设备的船去打捞时，渔网往往又不见了。作者在第二段描述了幽灵渔网造成的问题以及处理这些问题所面临的困境，也就是构建了一个问题背景，故选D。]
7.Hw d Tangara Blue Fundatin’s buys utperfrm earlier trackers？
A.They need less maintenance.
B.They mnitr brader regins.
C.They receive gvernment funding.
D.They prvide precise tracking data.
A [细节理解题。最后一段讲官方早期使用的追踪器是电池供电的。再根据最后一段的“Tangara Blue Fundatin’s apprach differs in that its recycled buys are slar-pwered and require less upkeep”可知，Tangara Blue Fundatin使用的浮标与早期追踪器的不同之处在于这些回收的浮标是太阳能供电的，且需要更少的维护。故选A。选项中的 maintenance与文中的upkeep是同义词。]
8.What is the best title fr the text？
A.Turning Waste int Treasure： A Fix t Ghst Nets
B.Fighting Threats： The Hidden Harm f Ghst Nets
C.Financing Change： Innvative Ocean Cleanup Plans
D.Prtecting Seas frm Waste： An Activist f Cnservatin
A [主旨大意题。本文主要讲述了Tangara Blue Fundatin 组织使用回收的带有全球定位系统功能的浮标追踪幽灵渔网，故A项“变废为宝：解决幽灵渔网的方法”最适合作本文标题。]

(2025·石家庄普通高中毕业质检)King Shahryar，betrayed (背叛) by his wife，decides t marry a new wman each night and have her killed by mrning t ensure he is never betrayed again.Scheherazade vlunteers t marry the king.Each evening，she begins an engaging stry but stps at dawn，leaving him eager fr mre.Night after night，she keeps him attracted with new tales，and ver 1，001 nights，the king falls in lve with her and abandns his cruel ways.
This ancient tale frm One Thusand and One Nights highlights strytelling’s impact.Our recent research shws that strng strytelling skills can dramatically imprve smene’s well-being.
At its cre，strytelling helps peple find meaning frm life’s chas.Studies shw we shape ur identities by turning experiences int persnal stries.Skilled strytellers excel at tw key skills： They need t cnnect events lgically and they must learn t see the wrld thrugh the eyes f their characters，understanding the “why” f what drives peple.Applying these tw skills t their wn lives，skillful strytellers use the first t identify and pursue what gives their life meaning，while the secnd develps a mindset that priritizes the “why” behind their actins ver just the “hw”.
T illustrate this pint，we cnducted studies with 800 participants.We measured strytelling ability thrugh self-reprts，friend evaluatins and expert reviews n lab experiments where each participant tld ne stry abut himself and the ther with three given randm wrds.In additin t these assessments f strytelling skills，we asked participants questins t get a sense f hw meaningful they fund life and whether they apprached decisins with a “why” mindset rather than a “hw” mindset.
Results cnsistently linked strytelling skills t strnger life meaning and gal clarity.Persnality als mattered： Peple pen t new experiences cllected mre interesting life stries，while shy peple used strytelling t balance ut their limited scial interactin.
A strng “why” mindset cnnects with reduced stress and extended life.Strytelling als builds scial cnnectins.By helping peple express their purpse and build relatinships，stries may indirectly strengthen bth mental and physical health.
Strytelling wrkshps，nw ppular glbally，may d mre than teach cmmunicatin—they culd help participants redefine their life’s directin.

The study，published in the jurnal Science，uncvers genetic mechanisms (遗传机制) behind rt “hydrpatterning”，r hw plant rts branch tward water and avid dry spaces in sil.In particular，the researchers discvered that ethylene，a plant hrmne (激素) knwn t help bananas ripen，als influences hw rts grw t seek water.
Fr this study，the researchers develped a new，simplified way t study water sensitivity in rts.They fund crn varieties adapted t ht and wet regins like Mexic were very gd at making new rt branches tward water and aviding dry areas.In cntrast，the varieties adapted t mderate regins f Nrth America frequently grew rts randmly withut distinguishing between dry and wet areas in the sil.
“Interestingly，the plants that are better at sensing where the water is are als making deeper rt systems，” said lead authr Jhannes Scharwies.“One idea is that if the plant desn’t waste time grwing rt branches int places where it desn’t find any water and nutrients，then it has mre energy t grw deeper dwn where water is mre likely.”
Genetic analyses reveal tw plant hrmnes，auxin and ethylene，play a rle in hw crn rts respnd t water.While auxin was already knwn t help cntrl this prcess，ethylene’s invlvement was a new discvery.In experiments with thale cress—a mdel plant ften used in research—the researchers fund auxin signaling prmtes rt branch develpment tward water，while ethylene stps branching when the rt is expsed t air.
Further research is needed t better understand the interactin f these genetic pathways befre crn varieties can be develped with mre drught-resistant rt systems，but the findings highlight the significance f studying these lcalized respnses at rt tips，researchers said.

2.What can be inferred frm Jhannes Scharwies’ remarks？
A.Plant hrmnes make a big difference t rt grwth.
B.Nutrients guarantee better water-seeking rt systems.
C.Rt branching cnserves energy fr higher prductin.
D.Strnger hydrpatterning is linked t greater rt depth.
D [推理判断题。根据第四段的“Interestingly，the plants that are better at sensing where the water is are als making deeper rt systems”可知，Jhannes Scharwies说那些更善于感知水源位置的植物，其根系系统也更深。由此可知，植物根系的“向水性模式”越强大，其根越深，故选D。]
3.What des Paragraph 5 mainly talk abut？
A.Mdel plants in research.
B.Hrmnes’ rle in rt grwth.
C.Genetic analysis methds.
D.Findings f previus research.
B [主旨大意题。第五段首句是本段的主旨句，即基因分析显示，两种植物激素——生长素和乙烯——在玉米根系对水分的反应中发挥着作用，接着分别介绍两种植物激素所发挥的不同作用。所以第五段主要讲激素在根系生长中的作用，故选B。]

(2025·郑州高中毕业年级第二次质量预测)Duncan Jurman became interested in butterflies when he was arund 5 years ld.He nticed a cuple f caterpillars (毛虫) in his backyard and was attracted by the different ways that caterpillars can disguise (伪装) themselves t stay safe in ptentially dangerus surrundings.Frm there，he started t learn mre abut caterpillars and butterflies.
Jurman believes that butterflies play a crucial rle in ur ecsystems.They’re very lw n the fd web，s they supprt a lt f different species that rely n them.They’re an indicatr species fr the health f the envirnment.Once they disappear，everything else is sn t fllw.
Jurman’s gal is t transfrm the landscape f Flrida’s Brward Cunty by turning a weedy suburb int a lively butterfly reserve at a time when insect ppulatins are decreasing quickly wrldwide.Jurman believes that every flwer planted is a ptential hme and surce f fd fr caterpillars and butterflies.He eventually develped a butterfly-friendly garden in his backyard by researching the different plants that butterflies prefer.He has already raised and released mre than 5，000 butterflies frm his garden.
Jurman als launched the Bring Butterflies Back campaign t educate peple abut butterflies and invite them t jin his cause f prtecting butterflies.He said that a lt f peple are surprised t learn that insects are declining at such an alarming rate，largely because the decline has been s gradual.This phenmenn helps t explain why peple are unwilling t take meaningful actins t save the envirnment.
In 2018，Jurman helped t build a butterfly garden at his high schl.The garden has had a regenerative effect n the surrunding envirnment—birds，native lizards，and ther insects have returned in great numbers.Other schls have been inspired t start gardens.“I dn’t knw if we can ever reach the pint that we were nce at with butterflies，but I think that if everyne gets invlved and starts their wn garden，they can make their wn impact，” Jurman said.
[语篇解读]本文是记叙文。本文主要讲述了Duncan Jurman在保护蝴蝶方面的努力，包括发起“让蝴蝶回归”的运动，在他的后院开发了一个蝴蝶友好型的花园，在他学校建立蝴蝶花园等。他还呼吁人们都参与到蝴蝶保护中来。
5.What des Paragraph 2 mainly talk abut？
A.The fd chain f insects.
B.The cmpetitin between species.
C.The ptential danger t butterflies.
D.The vital rle f butterflies in nature.
D [主旨大意题。根据第二段内容可知，首句“Jurman believes that butterflies play a crucial rle in ur ecsystems”(Jurman认为蝴蝶在我们的生态系统中扮演着至关重要的角色)为段落主旨句，后面内容(蝴蝶在食物网的位置很低，所以它们养活了很多依赖它们的不同物种。它们是环境健康的指示物种。一旦它们消失，其他的东西很快就会跟着消失)都是对这一句话的解释。所以本段主要讲述了蝴蝶在自然中的重要角色，故选D项。]
6.Why did Jurman create a butterfly-friendly garden？
A.T teach peple abut butterflies.
B.T study butterflies’ favrite plants.
C.T increase the number f butterflies.
D.T imprve the beauty f his backyard.
C [推理判断题。根据第三段可知Jurman的目标是改变佛罗里达州布劳沃德县的景观，在全世界昆虫数量迅速减少的时候，把杂草丛生的郊区变成一个令人兴奋的蝴蝶保护区。他最终在他的后院创建了一个蝴蝶友好型的花园。他已经在自己的花园里饲养并放飞了5 000多只蝴蝶。所以可以推测他创建蝴蝶友好型的花园是为了增加蝴蝶数量，故选C项。]
7.Which shws the phenmenn mentined in the text？
A.Peple’s unawareness f envirnmental changes.
B.The impact f human activities n insect habitats.
C.The rapid decline f butterfly ppulatins wrldwide.
D.The prcess f transfrming natural landscapes int reserves.
A [推理判断题。根据第四段内容可知，Jurman说许多人发现昆虫数量正以惊人速度减少时是很惊讶的，主要是因为下降是逐渐的，这种现象帮助解释为什么人们不愿意采取重大行动保护环境。所以推断文中提到的现象是人们没有注意到自然环境的变化。故选A项。]
8.What can be inferred frm Jurman’s wrds in the last paragraph？
A.Mre gardens are built t increase the number f ther insects.
B.Jurman is pessimistic abut the future f the butterfly ppulatin.
C.It’s impssible t restre butterflies’ ppulatin t their previus levels.
D.Peple’s jint effrts can have a great impact n the butterfly ppulatin.
D [推理判断题。根据最后一段Jurman说的话(我不知道我们是否能达到我们曾经对蝴蝶的保护程度，但我认为，如果每个人都参与进来，开始自己的花园，他们就能产生自己的影响)可推知，人们的共同努力可以对蝴蝶种群产生很大的影响。故选D项。]

Scientists at Linköping University in Sweden said that a “brain f gld” might just be what we need t fight nervus system diseases.The plan is t put gld electrdes (电极) int the affected part f the brain.They will act as “telephne peratrs” between nerve cells and electrnic medical devices，enabling cmmunicatin s that the nervus system can functin nrmally.
Treatment plans that invlve cnnecting medical devices t the brain already exist.Hwever，the electrdes used are usually made f hard metals，while the brain is like a jelly that “shakes” at the bdy’s slightest mvement.
“As the bdy is cnstantly in mtin，achieving clse cntact between smething that is hard and smething that is sft and breakable becmes a prblem，” explained Klas Tybrandt，ne f the scientists.
This is why the Swedish scientists are using a new material called “gld nanwires” (金纳米线).As the name suggests，these are lng，extremely thin gld threads—1，000 times thinner than human hair.By putting them int rubber，the scientists have successfully created electrdes that are sft enugh t cnnect cmfrtably with the human brain.
Gld can be made int structures as small as nanwires.Accrding t Live Science，gld can be stretched，pressed r even rlled int all kinds f shapes withut breaking.What’s mre，gld desn’t react with ther chemicals in the human brain，making it a safe chice.Once placed in the brain，gld nanwires can last fr at least three years，which is lnger than many materials currently in use.

10.What can we learn abut gld nanwires？
A.They are harder than rubber.
B.They are as thin as human hair.
C.They can be placed int the brain.
D.They are in the final stage f develpment.
C [细节理解题。第二段讲到方案是把金电极置于大脑的受影响区域；再根据第五段可知，瑞典科学家正在使用一种名为“金纳米线”的新材料，通过将其置于橡胶中，科学家成功创造出了足够柔软的电极(即第二段中的金电极)，可以舒适地与人类大脑连接。所以可知“金纳米线”可以被放入大脑中。故选C项。]
11.Why is gld a safe chice fr use in the brain？
A.It can be stretched by the brain.
B.It can be made int varius shapes.
C.It is being used t create sft electrdes.
D.It has n negative impact n the brain’s functins.
