Duglas Smith, n gardener frm Hertfrdshire. the U.K., recently set a new Guinness Wrld Recrd fr the mst tmates grwn n a single stem (茎), 1,269.
Up until last summer, the recrd fr the mst tmates grwn n a single stem had std unchallenged fr ver a decade. Then English farmer Duglas Smith set his sight n breaking it, thinking that he culd grw mre than 488 fruits n s single stem. He prved that last year, when he managed t break the ld recrd by grwing 839 tmates n a greenhuse -grwn plant. It was quite an achievement, but he was nly getting started, as nly a few weeks later Duglas Smith brke his wn recrd by grwing n less than 1,269 tmates n a single stem.
Is Duglas Smith a gardening addict? He spends up t fur hurs a day in his back garden tending his plants, and has been wrking hard n becming the best pssible gardener the wrld has ever seen. T maximize his chances f setting a new wrld recrd, he read varius scientific papers and even tk sil samples t be tested in a labratry. And in the end, they all paid ff.
“I am ver the mn,” Duglas said. “This year was nly meant t be an experimental year t see which varieties wuld prduce the mst fruits and we had t fight with early blight (疫病), which put paid t a number f ther tmat plants. I’m amazed by hw many tmates were n the plant in the end.”
Grwing 1,269 tmates n a single stem is nly Duglas Smith’s latest achievement. In 2020, he grew a 20-ft-tall sunflwer, and als set a new natinal recrd fr the heaviest tmat, with a 3.106 kg tmat. He likes t run little experiments n ther vegetables and crps, and he is currently experimenting n peas, aubergines and ptates.

2．Which f the fllwing can describe Duglas Smith best?
A．Strict and tlerant.B．Attractive and brave
C．Patient and hard-wrking.D．Friendly and humrus.
3．What may be a challenge fr Duglas Smith t break the ld recrd?
A．A lack f mney.B．Skill shrtages.
C．Building a labratry.D．Dealing with the blight.
4．What is the last paragraph mainly abut?

Just as the shiny brchure prmised, frm the mment I set ft n the Harvard campuslast fall, I was expsed t an exciting andenlightening new wrld.
I was brn and raised 1, 500 miles away, in a small apartment in Jacksn, Mississippi. I am the nly child, s my mther verpwered me with her lve. Fr smene wh sees s much beauty in the wrld, she wrked awfullyhard t prtect me frm it. Televisin, rap music, and even basketball with the kids n the blck was beynd cnsideratin. It left me a bit bitter as a teenager, but I grew t appreciate her enrmus sacrifices(牺牲) — walking me t the library every afternn, labring at multiple jbs t keep fd n the table, and telling me stries late int the night.
When I annunced the summer befre my senir year f high schl that I had decided t apply t Harvard, I nticed her hesitant lk befre a warm smile envelped her face. I pretended nt t see, but I was never able t frget it. I tried t explain my reasns fr wanting t leave-t prve I was smart enugh, fear f taking the path f least resistance, the classic teenage feeling f being trapped — but the wrds just made me sund shallw and ungrateful.
Nevertheless, I began t wrk n the cllege applicatins-an early ne fr Harvard and rughly a dzen thers standing by. I knew the chance f getting int Harvard was nt in my favr. T my jy, I was infrmed f my acceptance int Harvard three days befre my birthday. That night, after all f the celebratry texts and hugs, I sat in my rm and began t cry uncntrllably.
Over the curse f this year, I have changed in ways I never anticipated. I think I knw nw why my mther let me g. Harvard has frced me t grw and take a fair lk at the wrld, and at myself. Needless t say, I wuld nt trade the experience fr anything.

One f the mst cmmn beliefs amng researchers is that humans first arrived in Nrth America 16,000 years ag. Accrding t a recent fssil discvery, that might nt be true. The new finding suggests that humans might have arrived in Nrth America far earlier.
In 2013, a damaged mammth (猛犸象) skull and ther bnes that lked “deliberately brken” were fund. The damage t the bnes suggested that humans were the nes wh caused it t make tls. Carbn- dating analysis suggested the pieces are rughly 37 ,000 years ld. This discvery culd shift ur understanding f humans ‘earliest existence in Nrth America. These fssils suggest humans killed animals in the area much earlier than 16, 000 years ag.
Previus research led scientists t believe the first humans that settled in Nrth America belnged t the Clvis culture. This was a grup f peple wh left behind carefully made tls 16,000 years ag. Hwever, carbn-dating analysis f the mammth bnes indicates that the site is arund 36, 250 t 38, 900 years ld. That means it’s the ldest knwn site left behind by ancient humans in Nrth America.
“That’s nt the nly interesting thing abut the discvery,” said Timthy Rwe, a prfessr at the University f Texas. “The similar findings supprting an earlier date fr human arrival have been mstly ignred. This is because they have cntradicted previus research.”
Nw, hwever, he thinks there’s a gd chance that researchers will find evidence f humans farther back in time.
The early humans shaped bnes int sharp blades, which were used t take apart animals’ remains, accrding t Rwe. There are als signs that they cked the animal bnes ver a fire t melt ff the fat. “The real evidence that we have has t d with the breakage patterns, and hw thrugh they are. They must have used rcks r hammer stnes t bust the skeletn apart... These peple wuld use whatever they culd,” Rwe tld USA Tday.
1．What can be learnt abut the earliest humans in Nrth America?
A．They arrived there 16,000 years ag.B．They caused mammth t disappear.
C．They belnged t the Clvis culture.D．They culd make tls with bnes.
2．Why are the findings similar t the new ne ignred?
A．They lack a gd chance.B．They fail t draw attentin.
C．They disagree with earlier research.D．They aren’t studied scientifically.
3．Hw des Rwe find the new discvery?
A．Inspiring.B．Annying.C．Puzzling.D．Embarrassing.
4．What can be a suitable title fr the text?
A．The Earliest Humans’ Settling in Nrth America

The universe is incredibly vast. The diameter (直径) f the bservable universe is estimated t be abut 93 billin light years acrss. With just ur eyes, we can generally nly see a few thusand light years wrth f distance thugh there are sme bjects we can see that are much further away. The farthest bject we can see with ur eyes is Andrmeda Galaxy (仙女座星系) lcated 2.5 millin light years away, and yet it is nly visible if there is little light pllutin. In rder t see farther int space, we must rely n telescpes. Hw far can we see using the mst pwerful telescpes?
The Hubble Space Telescpe (HST) was the recrd hlder fr the farthest visible distance in space until the launch f the James Webb Space Telescpe (JWST) in 2021. JWST is nw the mst pwerful telescpe ever built, and it is able t see the universe as it was nly 200 millin years after the Big Bang. That means that JWST is able t piece tgether an additinal 300 millin years f universal histry cmpared t HST. JWST will be able t study sme f the first galaxies t frm after the Big Bang.
The farthest physical distance we can see is the Csmic Micrwave Backgrund Radiatin (CMBR). CMBR can be thught f as the ech (回声) f the Big Bang as it is the leftver radiatin frm the birth f the universe. The CMBR itself is the farthest pssible distance humans can see as it represents the mment that the universe became transparent t light. Althugh light did exist befre CMBR, gas and dust were simply t dense fr light t crss space. CMBR frmed nly 380,000 years after the Big Bang, and s we are seeing the universe prir t the frmatin f even the first stars.

Nearly 10 millin peple wrldwide live with Parkinsn’s disease. While Parkinsn’s is incurable, sme f its wrst symptms can be relieved and cntrlled using medicatins. A majr prblem f getting effective treatment at the right time is identifying the disease sn enugh, befre patients experience the symptms brught n by irreversible(不可逆转的)neurn lss.
But scientists might have just the thing t change the situatin. And it invlves a nse. In a study published in the jurnal ACS Omega, researchers frm China’s Zhejiang University created an “e-nse, ”a prtable device that can detect bdy smells specific t Parkinsn’s patients.
It may cme as a surprise t learn Parkinsn’s patients have their wn smells. But after a retired nurse in Sctland made headlines in 2015 fr a heightened sense f smell that led t her wn husband’s Parkinsn’s diagnsis, scientists have been trying hard t create a device that culd smell the disease befre physical symptms start t shw.
Over the years, scientists have fund peple with Parkinsn’s tend t prduce mre sebum (皮脂)than the average persn. This sebum mixes with ther verprduced substances t prduce certain, unique smells.
T track dwn these smells, the Zhejiang University researchers swabbed(用拭子擦拭)the upper backs f 31 Parkinsn’s patients and 32 healthy vlunteers. Using machine-learning sftware, they were able t identify three smell cmpunds that healthy vlunteers lacked. The researchers then tested the e-nse n sebum taken frm 12 Parkinsn’s patients and 12 healthy peple. The device was fund t be abut 71 percent accurate in distinguishing healthy sebum frm Parkinsn’s sebum.
These are encuraging findings, but befre the e-nse is ready fr clinical use, the team needs t test it n many mre peple t imprve the accuracy f the mdels. They will als need t test whether factrs like race affect the e-nse’s perfrmance in any way. But fr nw, as the number f peple living with Parkinsn’s in the U. S. is expected t rise t 1.2 millin by 2030, a nse might be the best ptin t detect this disease.
1．What makes it difficult fr Parkinsn’s patients t get effective treatment?
A．Its medicatins are in shrt supply.
B．It invlves irreversible neurn lss.
C．Its early signs are nt easy t ntice.

A．Her husband’s bdy gave ff a strange smell.
B．Her husband had a heightened sense f smell.
C．A smell caused her husband t suffer frm a disease.
D．A smell culd relieve her husband’s Parkinsn’s symptms.
3．What will the researchers d cncerning their inventin?
A．Put it int clinical use.
B．Cnduct a brader test.
C．Create mre lab mdels.
D．Expand its market utside the U. S.
4．What is the best title fr the text?
A．This e-nse can smell Parkinsn’s

【文章大意】这是一篇说明文。文章主要讲的是患有帕金森病的患者在获得有效的救治之前往往很难发现早期的症状，针对于这个问题研究人员研发出了一种可以检测出患者在身体症状出现之前的特有气味的便携式设备——“电子鼻”。
1．推理判断题。根据文章第一段“A majr prblem f getting effective treatment at the right time is identifying the disease sn enugh, befre patients experience the symptms brught n by irreversible(不可逆转的)neurn lss.(在正确的时间获得有效治疗的一个主要问题是，在患者经历不可逆的神经元损失带来的症状之前，尽快确定疾病。)”可知只有尽快确定疾病，帕金森患者才能在正确的时间里得到有效的救治，所以可以推断出早期症状的难以发现使帕金森患者得到有效救治变得困难。故选C项。
2．细节理解题。根据文章第三段“But after a retired nurse in Sctland made headlines in 2015 fr a heightened sense f smell that led t her wn husband’s Parkinsn’s diagnsis(但2015年，苏格兰一名退休护士因为她敏锐的嗅觉帮助其丈夫被诊断出帕金森病而上了头条。)”可知这名苏格兰退休护士发现她丈夫的身体发出一种特殊的气味。故选A项。
3．细节理解题。根据文章最后一段“These are encuraging findings, but befre the e-nse is ready fr clinical use, the team needs t test it n many mre peple t imprve the accuracy f the mdels. They will als need t test whether factrs like race affect the e-nse’s perfrmance in any way.(这些都是令人鼓舞的发现，但在电子鼻投入临床使用之前，研究小组还需要在更多的人身上进行测试，以提高模型的准确性。他们还需要测试种族等因素是否会以任何方式影响电子鼻的性能。)”可知为了提高模型的准确性，在电子鼻投入临床使用之前，研究小组还需要进行更广泛的测试。故选B项。
4．主旨大意题。文章第一段主要讲的是电子鼻出现的背景——帕金森病人在得到正确救治之前很难发现其症状，第二、三、四和五段主要围绕着电子鼻的研发，测试及功效展开，最后一段“These are encuraging findings, but befre the e-nse is ready fr clinical use, the team needs t test it n many mre peple t imprve the accuracy f the mdels. They will als need t test whether factrs like race affect the e-nse’s perfrmance in any way. But fr nw, as the number f peple living with Parkinsn’s in the U. S. is expected t rise t 1. 2 millin by 2030, a nse might be the best ptin t detect this disease.(这些都是令人鼓舞的发现，但在电子鼻投入临床使用之前，研究小组还需要在更多的人身上进行测试，以提高模型的准确性。他们还需要测试种族等因素是否会以任何方式影响电子鼻的性能。但目前，美国帕金森患者的数量预计将上升到120万。到2030年，电子鼻可能是检测这种疾病的最佳选择。)”向我们展示了电子鼻的使用前景，对全文进行总结。纵观全文，文章都是在围绕着一种能够测出帕金森患者身上特有气味的电子鼻展开，所以A项This e-nse can smell Parkinsn’s作为文章的标题最为合适。故选A项。

One f the mst cmmn beliefs amng researchers is that humans first arrived in Nrth America 16,000 years ag. Accrding t a recent fssil discvery, that might nt be true. The new finding suggests that humans might have arrived in Nrth America far earlier.
In 2013, a damaged mammth (猛犸象) skull and ther bnes that lked “deliberately brken” were fund. The damage t the bnes suggested that humans were the nes wh caused it t make tls. Carbn- dating analysis suggested the pieces are rughly 37 ,000 years ld. This discvery culd shift ur understanding f humans ‘earliest existence in Nrth America. These fssils suggest humans killed animals in the area much earlier than 16, 000 years ag.
Previus research led scientists t believe the first humans that settled in Nrth America belnged t the Clvis culture. This was a grup f peple wh left behind carefully made tls 16,000 years ag. Hwever, carbn-dating analysis f the mammth bnes indicates that the site is arund 36, 250 t 38, 900 years ld. That means it’s the ldest knwn site left behind by ancient humans in Nrth America.
“That’s nt the nly interesting thing abut the discvery,” said Timthy Rwe, a prfessr at the University f Texas. “The similar findings supprting an earlier date fr human arrival have been mstly ignred. This is because they have cntradicted previus research.”

5.【2025届青海省西宁市高三上学期一模】
Israeli researchers say they have invented a reusable face mask that can kill the crnavirus with heat by drawing pwer frm a mbile phne charger.
The disinfecting (消毒) prcess takes abut half an hur—and users shuld nt wear the mask while it is plugged in, said Prfessr Yair Ein-Eli, wh led the research team at Technin University in Haifa. The new mask has a USB prt that cnnects t a pwer surce such as a standard cell-phne charger that heats an inner layer f carbn fibres t 70 degrees Celsius, high enugh t kill viruses.
Ein-Eli said dispsable masks were nt ecnmically r envirnmentally friendly. “Yu have t make it reusable and friendly, and this is ur slutin,” he said.
Prfessr Alln Mses, an infectius diseases expert at Jerusalem’s Hadassah Medical Center, said there was “n questin” that a half hur’s expsure t 70-degrce heat wuld kill the crnavirus. But he cautined that repeated heating culd “damage the mask’s paper r fabric and spil its ability t prtect frm diseases in the future”.
During testing, the prttype was expsed t 20 heating cycles, each fr half an hur, with n impact n durability, Ein-Eli said. “We can guarantee it up t a few dzen cycles, withut any risk,” he added.
The prttypc lks like a standard N95 face mask, with a valve (阀) at the frnt and bands t hld it in place arund the head. The researchers submitted (递交) a patent fr the mask in the United States in late March and say they are discussing cmmercializing the prduct with the private sectr.
