An rchestra is attempting t bring peple living with dementia (痴呆) back int the present. The wrk being dne by Manchester Camerata has never been mre imprtant, given that there are abut 900,000 peple with the cnditin in the UK, a number that is predicted t nearly duble by 2040.
Peple with dementia ften find listening t music can reignite ld memries frm lng ag. Much mre verlked, thugh, is the impact that making music can have n the present. While sme with dementia can ften feel trapped in the past, sme researchers believe the act f creating music—as well as listening t it—can help t recnnect then t the here and nw.
A new BBC dcumentary—Dementia, Music and Us—fllws the wrk f Manchester Camerata and its principal flautist (长笛手) Amina Hussain. wh, als a prfessinal music therapist, leads classes acrss the nrth-west f England that have been described as life-changing. Classes fr the cmmunity cnsist f imprvisatin (即兴创作), singing, and writing their wn music.
Keith, 62, was diagnsed with dementia when he was 53. Like many, he really struggled t cme t terms with his new reality. He fund the sessins t be genuinely life-changing. “I think the thing that saved us was the first ever music grup we went t because frm that grup it pened ther grups up fr us.” he said. “The wrkshps make yu smile, enjy life and it just brings the best ut f yu.”
Researcher Dr Dwlen is seeking t better understand the “in the mment” benefits f music-making fr peple with dementia. She believes the imprvisatinal music wrkshp experience allws peple t “create smething that is held nw in the mment.” She added, “Imprvisatinal music-making is particularly imprtant fr peple with dementia, especially when it cmes t building their cnfidence and their self-esteem.”

In the 1950s, British histrian Nrtheaster Parkinsn came up with a cncept which was later knwn as Parkinsn’s Law f Triviality. It states that the amunt f time spent discussing an issue in an rganizatin is ppsitely assciated with its actual imprtance.
Parkinsn’s Law f Triviality is als knwn as “bike-shedding (车棚)”, after the stry Parkinsn uses t illustrate it. He asks readers t imagine a financial cmmittee meeting t discuss a three-pint agenda. The pints are as fllws: A prpsal fr a￡10 millin nuclear pwer plant; A prpsal fr a￡350 bike shed; A prpsal fr a￡21 annual cffee budget.
What happens? The cmmittee ends up running thrugh the nuclear pwer plant prpsal in little time. It’s t advanced fr anyne t really dig int the details. The discussin sn mves t the bike shed. Here, everyne’s an expert. In the end, the cmmittee runs ut f time and decides t meet again t cmplete their analysis.
Bike-shedding happens because the smaller a matter is, the mre peple will have an pinin n it, even when there is n genuine value t add. When smething is utside f ur circle f cmpetence, like a nuclear pwer plant, we dn’t even try t express an pinin. But when smething is cmprehensible, everyne wants t shw that they knw abut the tpic at hand.
Hw can we avid bike-shedding? The main thing yu can d is t have a clear purpse. Priya Parker, the authr f The Art f Gathering: Hw We Meet and Why It Matters, says that any successful gathering needs t have a fcused purpse. “Specificity,” she says, “is a crucial element.”
When it cmes t chsing yur list f invitees, Parker writes, “if the purpse f yur meeting is t make a decisin, yu may want t cnsider having fewer cks in the kitchen.” Getting the result yu want - a thughtful, educated discussin abut that pwer plant - depends n having the right peple in the rm.
5．What is Parkinsn’s purpse f presenting the imaginary meeting?
A．T state a fact.B．T clarify a cncept.
C．T make a predictin.D．T make a cmparisn.

A grup f Dexter cws fitted with mini-ludspeakers playing beats arund their necks has been gathered t graze (吃草) arund Little Dward Hill Frt (山堡), which was built in the 5th century BC, in the Wye Valley.
Grazing cws help supprt sil health, spread seeds and stp the plants frm grwing wildly, and the Wdland Trust hpes they will help restre the 820,000 square meters f wdland.
But t get rid f the need fr unsightly fences made f wden psts and rails which can prevent cws wandering ff, they are using new technlgy instead. A small device n a slar-pwered cllar will play a musical sund as the cws apprach a virtual fence tracked by a psitining system which als allws the Wdland Trust t change the grazing area the cws can enter when necessary.
“Little Dward is a really ancient and special site with nt nly the frt which lks ver the beautiful Wye Valley, but ancient wdland as well,” said Richard Brwn, Wdland Trust site manager. “It is a bit f a battle t prtect the frt frm plants and we have turned t grazing a small grup f friendly Dexter cws.” The wds cntain several rare species f wildlife, including the endangered Csnard’s net-winged beetle, a kind f insect. The site still cntains a significant number f ancient and dead trees which prvide deadwd fr its rare species.
“Fr nature and restratin the cws are ideal grazers acrss a wide range f species that help spread seeds thrugh their waste and gently mve the sil arund but withut destructin,” said Mr Brwn. “Fr the frt itself they are able t stp plants cmpletely surrunding it and the virtual fencing technlgy, with an app, helps us t mve the cws arund-in effect, mve the fence.” “The cws are very friendly t, s if peple d visit, dn’t be scared-they may just want t cme up t yu and say hell!”

Many experts have praised AI’s grundbreaking ptential t help peple becme way mre efficient at their jbs, and a lt f educatrs have been trying it ut fr themselves, including me.
I’ve used ChatGPT, an AI-pwered tl that can instantly answer seemingly any instructin, in my jb. Of curse, there are ptential dwnsides t the new technlgy. It can prduce inaccurate r ne-sided respnses based n faulty data it cllects, and it has the ptential t cause huge data privacy prblems. Despite thse risks, I have used such AI-pwered tls t plan lessns, prvide feedback n student assignments, and respnd t parent emails. And I’m lking fr ther ways t use the technlgy t make my jb easier.
Take tw ther teachers, fr example. Mike Kerr, a high schl English teacher in Tennessee, uses ChatGPT t reduce Lexile levels-the measure f an individual’s reading ability and the difficulty f a text -fr his students. High schl students are ften required t read relatively cmplex classic nvels. The reading hmewrk “can be a real big task fr an English learner in their first cuple f mnths here”. T help them, Kerr uses ChatGPT t give summaries f wrks f literature, which saves him frm having t read all the assigned literary wrks, s he can have mre time t better guide them thrugh the text.
April Edwards, a 6th grade scial studies teacher in Texas, shares ways that she uses AI in her instructin n a scial media platfrm. “I use AI t help create lessn plans, presentatins, t write emails, and t create checklists.AI is a great resurce t use as a starting pint fr a task r t give yu ideas,” Edwards said. She has nt intrduced AI t her students, because she wants t fully understand it befre allwing students t use it in the classrm. “My gal is t shw them hw t use AI respnsibly and effectively and demnstrate that t my students. If I am using AI irrespnsibly, then s will they,” Edwards said.

Since 2001, rbtic tls have revlutinized the practice f surgery. They have greatly reduced the stress and physical demands nrmally placed n surgens and have made certain prcedures pssible.
One example is “keyhle surgery”, r minimally invasive (微创) surgery, which nrmally requires surgens t stand at awkward angles and make difficult mvements with their hands t make a cut inside the patient. But in June 2022, surgen James Ansell used 3D glasses and tw sticks t cntrl fur rbtic arms t perfrm a prcedure t remve a cancerus tumr. “My clleague said... that this feels like cheating,” Ansell said t The Guardian.
Anther area f surgery that has had majr technlgical breakthrughs in recent years is telesurgery. Nrmally, telesurgery relies n a wired cnnectin due t cncerns f harming the patient shuld a wireless cnnectin drp during surgery, but China made several advancements in wireless telesurgery based n 5G technlgy.
China achieved the first 5G-based remte peratin in March 2019 invlving a brain surgery prcedure between a surgen in Sanya and a patient in Beijing, a distance ttaling nearly 3,000 kilmeters. Mre recently, a team f surgens successfully cmpleted remte micrn-level eye surgery n rabbits lcated in a different city. The rabbits were at the Sun Yat-sen University in Guangzhbù, Guangdn g prvince, whereas the surgical team wh perated n them via a 5G rbt were at the Hainan Eye Hspital in Haiku, Hainan prvince.
Lking t the future, peple hpe that remte surgery culd becme cmmnplace t help heal injured sldiers n the battlefield while keeping surgens at a safe distance. Sme even believe that rbtic systems, cmbined with AI, culd ne day exceed human surgens.
But, given current technlgical limitatins and the high csts f these rbts which can cst millins f dllars, the cmplete rbt takever f surgery may still be a while ff.

Shabati Devi grws rice and vegetables in the village f Ddhghat in Uttar Pradesh, India. One night, flds drwned her fields. Thankfully, she’d planted a special type f rice. Scientists had imprved its DNA t cntain a specific bit f genetic (基因的) material called SUB1A, which helps rice plants survive being cmpletely drwned fr tw weeks. Indeed, after the fld went away, rughly half f Devi’s rice crp was still alive. Nw sme scientists dn’t just want t help crps survive climate change. They’re lking t develp crps that actively fight climate change.
During phtsynthesis (光合作用), plants turn CO₂ frm the air int the carbn-rich sugar and xygen they need. Plants als send carbn int the sil thrugh their rts. Hwever, plants “can’t use all the sunlight when full sun is shining n the leaves,” ntes Krishna Niygi, a bilgist at UC Berkeley. Actually, t much sunlight can damage plant cells. T guard against this, plants have smething like a safety valve (阀). If it culd react t changing light faster, plants culd get mre sun energy, Niygi says.
Three prteins cntrl the pening and clsing f thse safety valves. T increase the levels f these prteins, Niygi’s team added three genes int tbacc plants. The result was that plants grew 14-20% larger than usual. This is imprtant as larger plants stre mre carbn.
Encuraging phtsynthesis t pull mre CO₂ frm the air is a great start t ward helping farms fight climate change, but this remval is shrt-term. When a plant dies, micrbes in the sil eat it. Thse micrbes then put ff CO₂ and ther greenhuse gases, which return t the air. The deeper plant rts grw int the sil, thugh, the lnger it takes that carbn t make its way back ut again. “The rts are the vehicle t actually stre the carbn and take it ut f the atmsphere,” says Wlfgang Busch, a bilgist at the Salk Institute in San Dieg, Califrnia.
Frm rt surveys and ther studies, Busch has identified arund 50 genes that help plants grw deeper, bigger rts.
21．What helped Devi’s crps survive the fld?
A．The enugh sunlight.B．The crps’ big rts.
C．A certain gene.D．Scientists’ immediate help.
22．Why did Niygi’s team try t increase the levels f the three prteins?
A．T ffer leaves’ safety valves mre prtectin.
B．T quicken a plant’s respnse t changing light.
C．T make it easier t add the genes int the plants.
D．T develp a certain plant with healthier leaves.

A．It is hard fr rts t take carbn ut f the atmsphere.
B．Remving carbn thrugh phtsynthesis is an easy prcess.
C．The sil undergrund plays a crucial rle in absrbing carbn.
D．Plants with deeper rts can be better fr lng-term carbn strage.
24．What can be a suitable title fr the text?
A．Crps Are Being Engineered t Handle Changing Climate

A new Wrld Bank reprt warns that children wh d nt get enugh gd fd in the first tw years f life suffer lasting damage. They may be underdevelped r under-weight. They may suffer frm pr health r limited intelligence. Besides, these children are mre likely t drp ut f schl and earn less mney as adults.
The reprt ntes that t little fd is nt the nly cause f pr nutritin. Many children wh live in hmes with plenty f fd suffer fr ther reasns.
The study als cnnects malnutritin (营养不良) t ecnmic grwth in pr cuntries. A lack f nutritin in early childhd can cst develping natins up t three percent f their yearly earnings. Many f these cuntries have same ecnmic prblems that are grwing at a rate f tw t three percent yearly. The study suggests that pr cuntries culd pssibly duble their ecnmic grwth if they imprved nutritin.
Africa and Suth Asia are affected the mst by pr nutritin. The study says abut half f all children in India d nt get enugh gd fd. The Wrld Bank study als ntes that rates f malnutritin in Suth Asia are almst duble thse in central and suthern Africa. . Other parts f the wrld are als seriusly affected, including Indnesia, Uzbekistan, Yemen, Guatemala and Peru.
The study recmmends that develping cuntries change their ways t deal with malnutritin. Instead f directly prviding fd, the study suggests educatinal prgrams in health and nutritin fr mthers with yung babies. It als recmmends cleaner living cnditins and imprvements in health care.
The Wrld Bank nutritin specialist Meera Shekar said the perid f life between pregnancy (怀孕) and tw years is very imprtant. Gvernments shuld take direct actin t imprve nutritin fr children during this perid.

During the 2020 Olympics in Tky, there was a lt f talk abut the envirnmental effrts taken. Athletes slept n beds made frm recycled cardbard. The medals were prduced ut f ld appliances such as smartphnes and laptps. Over 90% f Japanese cities, twns and villages participated in the tw-year effrt t cllect recycled materials t prduce 5000 medals. Eighty tns f small electrical devices were cllected t make this prject successful.
With the 2024 Olympics Games underway in Paris, new envirnmental effrts are cming int play. Observers will sit n chairs made f plastic recycled frm lcal bins. This decisin was made due t a lack f unused raw materials t make new seats, s the ec-cnstructin firm Le Pave turned t make the seats ut f waste. Arund 11,000 seats will be made frm recycled materials.
The plastic cllectin fr Paris 2024 has been carried ut in the regin’s schls, and ver five millin clured bttle caps have been recvered. Mrever, 80% f the 100 tns f recycled plastic needed t make the seats cme frm the yellw bins cllectins. This is all part f the Paris 2024 “zer waste” strategy t limit single-use plastic usage and encurage a circular ecnmy.
The Olympic Games rganizers are planning t make the Paris 2024 Games the greenest Olympic Games yet. They intend t emply a carbn-neutral apprach that will lessen the climate impact f the Games by predicting, aviding, reducing and balancing emissins and encuraging thers t get invlved. The Summer Games have emitted 3.6 millin tns f carbn emissins in previus years. The Paris 2024 Games has set a carbn budget f 1.5 millin tns which includes the emissins frm cnstructin, transprtatin and peratins f the Games.
These plans are ambitius but are achievable. If Paris 2024 successfully reduces emissins and prmtes a circular ecnmy, it might set the standard fr future Olympic and Paralympic Games, regardless f where they are held.
29．What were the 2020 Olympics medals made frm?
A．Raw metal.B．Recycled cardbard.

Cmmercial fishing is taking away life frm ur ceans. Mre than a third f glbal fish stcks were classified as verfishcd in 2017, and the Eurpean Unin (EU) is hping that investing in technlgy can help fix the prblem in its waters. It is funding a prject called SmartFish H2020, led by Nrwegian cmpany SINTEF Ocean, t design equipment t reduce the industry’s impact n sea life.
Amng the innvatins it is testing is a new kind f fishing net called SmartGear. It makes sunds and uses LED lights f different clrs and intensities t attract nly target species t the net, encuraging ther fish t swim away. “We want t make life easier fr the fishers,” Rachel Tiller, senir research scientist at SINTEF Ocean, says. “The prblem is that we dn’t have data. We dn’t knw hw many fish are in the cean and we need t find this infrmatin.”
Anther technlgy being trialed is CatchScanner. It prduces a 3D clr image f the fish, which is analyzed using AI t estimate the weight and identify the species. CatchScanner can als help tackle rule-breaking; sme fishing bats catch mre fish than EU qutas (MA) allw, as well as fish f the wrng size and species. CatchScanner can prevent this by autmatically cllecting catch infrmatin in a database and making it available t authrities such as natinal castguard agencies.
The EU cannt frce member states t adpt the SmartFish innvatins, and their success will depend n market demand. Hwever, Tiller says that many fishing cmpanies acrss Eurpe have shwn interest. “Sme f these technlgies can be very expensive,” she says. “S in rder fr the fishers t want t have them n bard, they need t see the benefit.”
Fisherman Aitr Larranaga will sn test SmartGear ff the cast f Spain. He’s enthusiastic abut smart tech and believes the fishing industry needs t innvate t becme mre sustainable. “The wrld mves n,” he says. “We can’t wrk like we did 200 years ag.”
33．What d we knw abut SmartGear?
A．It catches fish by physical means.
B．It uses AI t track fish escaping frm the net.
C．It wrks t find ut the number f fish in the cean.
D．It aims t prduce 3D images f different fish species.
34．What functin can CatchScanner serve?
A．It can direct fishers t waters full f fish.B．It can identify wrng-sized fishing bats.
C．It can reprt fishers’ unruly behavir.D．It can catch nly target fish species.
35．What may make fishers use the SmartFish innvatins?
A．The innvatins are affrdable fr them.B．The EU frces them t adpt the innvatins.
C．Fishing cmpanies ask them t g green.D．The innvatins help them make mney.
36．What is Aitr Larranaga’ s attitude tward the SmartFish innvatins?

Carried by the wind, dust particles (微粒) frm places such as the Sahara Desert can flat halfway arund the wrld befre settling t the grund. As the plastics abandned by humans break dwn int tiny pieces in the envirnment, they, t, travel thrugh the atmsphere. Nw scientists are a step clser t understanding hw these micrplastics travel in the glbe — bth lcally and n lng-distance flights.
Researchers spent mre than a year cllecting micrplastics frm 11 natinal parks and wilderness areas in the western U.S. They examined the particles that settled n dry days and thse that fell alng with rain r snw. In additin t making clear hw micrplastics mve arund, the results, published n Thursday in Science, reveal the seriusness f the prblem: mre than 1 millin kilgrams f micrplastics — the weight f 120 millin t 300 millin plastic water bttles — fall n prtected lands in the cuntry’s western regin each year.
The new findings add t scientists’ cncern ver micrplastic pllutin’s ptential impacts n the envirnment and human health. “We’re nt suppsed t breathe in this material,” says Steve Allen, a micrplastics researcher at the University f Strathclyde in Sctland, wh was nt invlved in the new study. “Plastics in the envirnment “carry all srts f pesticides (农药), heavy metals and all the ther chemicals that we’ve made ver time,” he adds. “They’re ging t carry them directly int ur lungs.”
Since their discvery in ceans in the 1970s, micrplastics — which can be as large as a grain f rice r smaller than a particle f dust — have been fund nearly everywhere researchers have lked: in cities, in Arctic snw, n remte muntaintps. Their presence in areas distant frm the place where human live has pinted t them being carried by winds.

Tday’s Brussels spruts (孢子甘蓝) taste better than yu might remember frm childhd, and that is because a new variety has replaced the riginal vegetable. Yu can thank plant breeders (植物育种家) fr the change. Mdern breeders, armed with new gene-editing technlgy, are lking t reprduce Brussels spruts’ reinventin.
In the late 1990s, scientists discvered specific chemicals which made Brussels spruts taste bitter. Plant breeders started grwing ld seeds, previusly abandned due t pr yields (产量), t lk fr tastier versins with lwer levels f these specific chemicals. Then they crssed these delicius but lw-yield plants with high-yield individuals until they fund a versin that made plenty f tasty spruts, transfrming the vegetable frm a bitter pill int a ppular dish.
But ther vegetables haven’t fared as well. That’s because mst breeding decisins favr plant traits that matter t vegetable grwers, nt vegetable eaters. Fr instance, disease resistance is prbably the majr fcus these days f mst breeding prgrams because that prevents the farmer frm grwing the crp. The taste f vegetables is ignred.
Peple, hwever, are nw becming interested in priritizing the taste f vegetables thanks in part t new genetic technlgy such as the gene-snipping technique CRISPR and DNA sequencing which is cheap enugh t use widely. “There’s never been a better time t be a fruit breeder r a vegetable breeder because we have mre tls and techniques,” says Susan Brwn, an apple breeder at Crnell University.
Sme cmpanies are beginning t use thse tls t deal with the challenge f develping tastier vegetables. One cmpany, Pairwise, is fighting the same cmpunds that trubled Brussels spruts: glucsinlates. But this time researchers are imprving the flavr f salad greens.
All vegetable grwers hpe that mre flavrful prducts n stre shelves will cnvince peple t cnsume the recmmended allwances (推荐量) f fruits and vegetables — and d s better than decades f nutritinal guidance have. “Dn’t waste yur time talking abut trying t educate peple t eat better,” said Harry Klee, a prfessr wh specializes in tmat breeding. “Just give them prducts that taste better and that they want t eat.”

Nuclear energy is ne f the cleanest pwer n earth. It is cleaner than any energy surce except wind. But that desn’t necessarily mean nuclear is the lng-term slutin fr the wrld because nuclear material is perhaps the mst pisnus matter n earth. In additin, uranium, the element mst cmmnly used in nuclear reactrs, is nt in limitless supply. But the biggest prblem is nuclear waste.
Hw can we deal with nuclear waste? The answer is simple—put them smewhere where they can stay, undisturbed, islated, frever. Finland is building just that. This regin is largely lacking in natural disasters. It really desn’t encunter any natural phenmenn that culd damage a nuclear waste strage site, especially if it’s 1, 500 feet undergrund. Beneath an island n the Finnish Baltic Sea cast, the cuntry is digging. They’ re building the very first permanent nuclear waste strage facility in the wrld in the stable bedrck 1,500 feet belw.
Currently they’ re just finishing their dig dwn, then very sn they’ll start filling the facility with nuclear waste. They’ll dig lng tunnels with small hles in which they’ll place nuclear waste then backfill the tunnels with clay t be left frever.
With this system, there’s near zer risk f nuclear material leaking ut int the grundwater and, nce it’s filled in the year 2120, it can just be left, frever. Because the material will be s far dwn and s difficult t get t, n human management will be necessary nce cmpleted.
N security, n maintenance, nthing which means it shuld be truly secure, but befre leaving it, Finland needs t fight against ne thing—human nature. As curius beings, it’s hard t fight a persn’s urge f discvery. If smene finds a mysterius structure frm thusands f years ag, it’d just be natural t want t pen it up, and that’s a prblem fr nuclear waste sites.
We essentially did just that with the pyramids in Egypt. These structures were built as the final, permanent resting places and we pened them up because we were curius. Opening the nuclear strage facilities wuld release radiatin int a future civilizatin, s we have t tell them t leave the sites alne, but that’s easier said than dne.
45．Why is Finland building a nuclear strage site deep undergrund?
A．The tunnels there are easy t dig.B．The supply f uranium is limited.
C．Mdern technlgy makes it pssible.D．N natural disaster can influence the site.

Mst f us trust ur dctrs even when they hand us a prescriptin fr a drug we can’t prnunce. But natural, hlistic (整体的) prducts are fully in vgue nwadays, and the Internet has created a way fr nn-experts t becme as r mre infrmed as their general practitiner when it cmes t bscure treatment methds. “Peple are nw mre willing t take their health and wellness int their wn hands,” says Danielle Hardee, a wellness advcate fr D TERRA Internatinal.
Oddly enugh, until fairly recently, Hardee was nt ne f thse peple. Her first experience with essential ils came in treating her pet bulldg. After seeking suggestins fr the sickly pet n Facebk, a fellw fsterer tld Hardee abut certain ils she culd try applying t the animal’s skin. Pairing her curisity with healthy skepticism, Hardee dve deep int researching the safety f the ils. “I was very happy with everything I fund,” she says. “I started nt just using them n the fster dg, but als ur sn, wh needed the benefits f the respiratry supprt.” While the dg’s recvery was sn apparent, the benefits fr her sn were almst immediate.
The ils in questin are cnsidered “essential” nt due t any prven vitality, but because they cntain the essence f the plants frm which they are extracted. Peppermint, lavender and citruses are amng the mst cmmn n the market tday, but numerus essential ils have been in use fr several centuries.
After seeing hw beneficial the cncentrated liquids were t bth the tw-legged and fur-legged members f her family, Hardee sn fund herself teaching essential il classes. “It became smething I felt s strngly abut, I had t share it,” she says. The classes quickly grew in size and gegraphical span and Hardee sn became an advcate fr dTERRA Internatinal, a natural nutritin and wellness cmpany.
As grwing ppularity pushes essential ils int the brader market, Hardee recmmends curius custmers prceed with cautin cncerning quality and purity. Hardee believes the effects f quality ils will be the evidence that helps them prevail. “I’m nt a hlistic health guru (专家),” she emphasizes. “I’m just seeing it with my wn eyes.”

Here is an astnishing and significant fact: Mental wrk alne cannt make us tired. It sunds absurd. But a few years ag, scientists tried t find ut hw lng the human brain culd labr withut reaching a state f fatigue(疲劳). T the amazement f these scientists, they discvered that bld passing thrugh the brain, when it is active, shws n fatigue at all! If we tk a drp f bld frm a day labrer, we culd find it full f fatigue txins and fatigue prducts. But if we tk bld frm the brain f an Albert Einstein, it wuld shw n fatigue txins at the end f the day.
S far as the brain is cncerned, it can wrk as well and swiftly at the end f eight r even twelve hurs f effrt as at the beginning. The brain is ttally tireless. S what make us tired?
Sme scientists declared that mst f ur fatigue cmes frm ur mental and emtinal attitudes. One f England’s mst all standing scientists, J.A．Hadfield, says,“ The greater part f the fatigue frm which we suffer is f mental rigin. In fact, fatigue f purely physical rigin is rare.” Dr. Brill, A famus American scientist ges even further. He declares,“ One hundred percent f the fatigue f a sitting wrker in a gd health is due t emtinal prblems”.
What kinds f emtins make sitting wrkers tired? Jy? Satisfactin? N. A feeling f being bred, anger, anxiety, tenseness, wrry, a feeling f nt being appreciated—thse are the emtins that tire sitting wrkers. Hard wrk by itself seldm causes fatigue. We get tired because ur emtins prduce nervusness in the bdy.
53．What surprised the scientists a few years ag?
A．Fatigue txins culd hardly be fund in a labrer’s bld.
B．Albert Einstein didn’t feel wrn ut after a day’s wrk.
C．The brain culd wrk fr many hurs withut fatigue.
D．A mental wrker’s bld was filled with fatigue txins.
54．Accrding t the authr, which f the fllwing can make sitting wrkers tired?
A．Unpleasant emtins.B．Challenging mental wrk.
C．Endless tasksD．Physical labr.
55．We can infer frm the passage that in rder t stay energetic, sitting wrkers need t ______.
A．have sme gd fdB．discver fatigue txins
C．exercise regularlyD．enjy their wrk
56．What is the best title fr this passage?

Wh has n regrets abut things dne in the past? Wuldn’t it be nice if, smehw, we culd g back t change a cuple f bad decisins? This sunds like science fictin.
The laws f physics prhibit traveling back in time fr many reasns. If we did travel back in time and changed the curse f events, we wuld be altering the curse f histry. An example ften cited is the grandfather’s paradx (悖论): If yur grandfather died when he was still a high schl student, he wuldn’t have met yur grandmther and yur father and yu wuldn’t exist.
Putting humans r cnsciusness traveling back in time aside fr the mment, is there anything in science even similar? Surprisingly, yes. At the level f quantum particles (量子粒子), there is smething called Wheeler’s delayed-chice experiments that shw that actins in the present can influence the past. The experiments use smething called the wave-particle duality (波粒二象性) f light and f matter. The fact that the physical nature f quantum bjects is undetermined until it is measured. In ther wrds, this means that a particle f light r f matter can behave either as a wave (spreading ut in space) r as a particle (staying tgether) depending n the measuring devices. Lng and nging discussins abut the nature f quantum physics are still trying t wrk ut what this actually means. D ur minds determine the nature f physical reality?
Shuld we ffer fd fr thught fr the future r the past? Unfrtunately, these experiments say very little abut hw we culd interfere with the past in events relevant t the human scale. Better t think carefully abut decisins than t try t fix them backwards.
57．What’s the purpse f mentining the paradx?
A．T shw it is interesting.

Every week, Angela lked at her recycling bin, filled with shamp bttles and plastic cntainers, with mixed feelings. Sure, it was a lt f plastic, but it was ging t be recycled. Or s she thught. Then, her husband sent her sme articles revealing that less than 6% f the cuntry’s plastic gets recycled. She was shcked.
Determined t cut back n her plastic cnsumptin, Angela gt a starter kit frm a cmpany selling refillable husehld cleaners (家用清洁器). In it were tablets, cntaining cncentrated hand sap as well as glass and bathrm cleaners, and fur empty cntainers. She filled each ne with tap water, then drpped in a tablet and watched it disslve. If she was happy with the cleaners, she wuld rder mre tablets but reuse the cntainers. N new plastic required.
Given plastic’s harmful effects n the envirnment, nearly three quarters f Americans say they are trying t reduce their reliance n single-use plastic, accrding t Pew Research Center. Since plastic is everywhere and aviding it altgether is extrardinarily difficult, sme, like Angela, have revived a nce-custmary practice: refilling cntainers. Husehld cleaners seem particularly prepared fr a refill revlutin, fr many can be easily cncentrated and recnstituted (with water. If just 10% t 20% f plastic packaging are reused, a reprt frm the Wrld Ecnmic Frum estimates, the amunt f plastic waste entering the cean will be cut in half.

Slar stills (蒸馏器) prvide a clever and simple means f purifying dirty r salty water, but they wrk at a rather slw rate. A new material has been shwn t bst their perfrmance, and it’s made frm fruit waste which wuld therwise be thrwn away.
In its mst basic frm, a cnventinal slar still cnsists f a basin f undrinkable water that is set beneath a cver. The water evaprates (蒸发) as it’s heated by the sun, cndensing (凝结) n the inside surface f the cver. That cndensatin—which is pure, clean water-drps dwn the cver and is cllected in a separate cntainer fr drinking. In rder t warm the dirty/salty water at a faster rate, scientists have develped materials that flat n its surface, transfrming sunlight int heat. They cmmnly use carbn btained frm cal.
T seek a less cstly and mre envirnmentally-friendly alternative, Prf. Edisn and clleagues at Singapre’s Nanyang Technlgical University lked t smething that is free fr the taking—fruit waste. Mre specifically, the scientists tried ut ccnut peels, range peels and banana peels.
In a simple carbnizatin prcess, the fruit waste was heated at 850℃fr a few hurs, and mixed with a kind f chemical substance. Ding s transfrmed the fruit waste int a new material which has a very highlight-t-heat transfrming efficiency.
When tested in a small slar still, this new material prved t be very effective at transfrming sunlight int heat, causing the dirty/salty water t evaprate much mre rapidly. And because the material is full f hles, the waters team is able t rise right thrugh it, subsequently cndensing n the inside f the still’s cver.
Prf. Edisn and his team fund material btained frm the ccnut peels wrked best, as it transfrmed sunlight t heat with an efficiency rate f 94%. They are nw develping the technlgy further, and are seeking industry partners t help with its cmmercializatin.

Ocean temperature extremes are nw nrmal, a new study reprts. It has analyzed cean surface temperatures fr the past 150 years. It reveals that by 2019, 57 percent f the cean’s surface was warming t temperatures rarely seen 100 years ag.
Eclgists wanted t learn hw ften mdern extreme heat events ccur. They als wanted t see hw lng they last. Kisei Tanaka was ne f thse eclgists. He nw wrks fr the Natinal Oceanic and Atmspheric Administratin (NOAA) in Hnlulu, Hawaii. Tanaka teamed up with Kyle Van Hutan, wh wrks at the Lggerhead Marinelife Center. The tw analyzed mnthly sea surface temperatures cllected frm 1870 thrugh 2019. Then they mapped where and when extreme heat events had shwn up, decade by decade.
By lking at mnthly extremes instead f annual averages, the tw fund that ver time, mre and mre patches (区域) f water were reaching extreme temperatures. Then, in 2014, the entire cean hit a pint f n return, Van Hutan says.
Heat waves harm cean ecsystems. They can lead seabirds t starve... And animals—frm fish and whales t turtles—may have t swim lng distances in search f cmfrtable temperatures.
In May 2020, NOAA annunced that it was updating what climates it nw cnsidered “nrmal”. These values are what the agency uses t put daily weather events in a histrical cntext. The average values frm 1991 t 2020 are nw higher than thse frm 1981 t 2010, NOAA fund.
Van Hutan says his new study shws extreme cean warming is nw the nrm. Much discussin n climate change, he ntes, has been abut future events, and whether r nt they might happen.

Research has fund that using wd fr cnstructin instead f cncrete and steel can reduce emissins. But Tim Searchinger at Princetn University says many f these studies are based n the false fundatin that harvesting wd is carbn neutral (碳中和). “Only a small percentage f the wd gets int a timber (木料) prduct, and a part f that gets int a timber prduct that can replace cncrete and steel in a building,” he says. Efficiencies vary in different cuntries, but large amunts f a harvested tree are left t be divided int parts, used in shrt-lived prducts like paper r burned fr energy, all f which generate emissins.
In a reprt fr the Wrld Resurces Institute, Searchinger and his clleagues have mdelled hw using mre wd fr cnstructin wuld affect emissins between 2010 and 2050, accunting fr the emissins frm harvesting the wd. They cnsidered varius types f frests and parts f wd ging twards cnstructin. They als factred in the emissins savings frm replacing cncrete and steel.
Under sme circumstances, the researchers fund significant emissins reductins. But each case required what they cnsidered an unrealistically high prtin f the wd ging twards cnstructin, as well as rapid grwth nly seen in warmer places, like Brazil. In general, they fund a large increase in glbal demand fr wd wuld prbably lead t rising emissins fr decades. Accunting fr emissins in this way, the researchers reprted in a related paper that increasing frest harvests between 2010 and 2050 wuld add emissins equal t rughly 10 percent f ttal annual emissins.
Ali Amiri at Aalt University in Finland says the reprt’s cnclusins abut emissins frm rising demand are prbably crrect, but the stry is different fr wd we already harvest. “Bsting the efficiency f current harvests and using mre wd fr lnger lived purpses than paper wuld cut emissins,” he says. “We cannt just say we shuld stp using wd.”

Elephants eat plants. That’s cmmn knwledge t bilgists and animal-lving, schlchildren alike. Yet figuring ut exactly what kind f plants they eat is mre cmplicated.
A new study frm a glbal team that included Brwn University cnservatin bilgists used innvative methds t efficiently and precisely analyze the dietary habits f elephants in Kenya. Their findings n the habits f individual elephants help answer imprtant questins abut grup fd searching behavirs, and aid bilgists in understanding the cnservatin appraches that best keep elephants nt nly sated (饱的) but satisfied.
“When I talk t nn-eclgists, they are surprised t learn that we have never really had a clear picture f what all f these large animals actually eat in nature,” Kartzinel, an expert btanist wh has cnducted field research in Kenya, said. “The reasn is that these animals are difficult and dangerus t bserve frm up-clse, they mve lng distances, they feed at night and in thick bush and a lt f the plants they feed n are quite small.”
Then the team cmpared the diets f individual elephants thrugh time. In their analysis, they shwed that dietary differences amng individuals were ften far greater than what had been previusly assumed, even amng family members that ate tgether n a given day.
This study helps address a classic paradx (悖论) in wildlife eclgy. Kartzinel said: “Hw d scial bnds hld family grups tgether in a wrld f limited resurces?” In ther wrds, given that elephants all seemingly eat the same plants, it's nt bvius why cmpetitin fr fd desn't push them apart and frce them t search fr fd independently.
“The simple answer is that elephants vary their diets based nt nly n what’s available but als their preferences and physilgical needs,” said Kartzinel. These findings help infrm theries f why a grup f elephants may search fr fd tgether: The individual elephants dn't always eat exactly the same plants at the same time, s there will usually be enugh plants t g arund.
These findings may ffer valuable insights fr cnservatin bilgists. T prtect elephants and create envirnments in which they can successfully grw their ppulatins, they need a variety f plants t eat.
