第二部分 阅读理解(共两节,满分40分)
第一节(共15小题;每小题2分,满分30分)
阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项，并在答题卡上将该项涂。
A
Scientists have discvered a "mnster black hle" s massive that, in thery, it shuldn't exist
It’s a stellar black hle---the type that frms after stars die, cllapse, and explde. Researchers had previusly believed that the size limit was n mre than 20 times the mass f ur sun because 8S these stars die, they lse mst f their mass thrugh explsins that expel matter and gas swept away by stellar winds
This thery has nw been tppled by LB-1, the newly discvered black hle. Lcated abut 15.000 light years away, it has a mass 70 times greater than ur sun, accrding t a press release frm the Chinese Academy f Sciences.
The findings were published by Chinese researchers in the jurnal Nature n Wednesday.
"Black bles f such mass shuld nt even exist in ur galaxy, accrding t mst f the current mdels f stellar evlutin," said Liu Jifeng, head f the team that made the discvery. "LB-1 is twice as massive as what we thught pssible. Nw therists will have t take up the challenge f explaining its frmatin."
Scientists are nw scratching their heads at hw LB-1 gt s huge.
The Chinese team has prpsed a number f theries. LB-1' sheer size suggests that it “was nt frmed frm the cllapse f nly ne star," the study said--- instead, it culd ptentially be tw smaller black hles rbiting each ther.
Anther pssibility is that it frmed frm “fallback supermva.” This is when a supernma---the last stage f an explding star---ejects material during the explsin, which then falls back int the supernva, creating a black hle.
This fallback frmatin is theretically pssible, but scientists have never been able t prve r bserve it. If this is hw LB-1 frmed, then we may have "direct evidence fr this prcess” fr the first time, the study said.
There are several types f black hles and stellar black hles like LB-1 are n the smaller side, accrding t NASA．Supermassive black hles are much bigger---they can be billins f times the mass f ur sun,
Scientists believe supermassive black hles may be cnnected t the frmatin f galaxies, as they ften exist at the center f the mass star stems but it is still nt clear exactly hw, r which frm first.
21．Why des the writer write the article?
A．T reprt the great achievement Chinese scientists have made in black hle thery,
B．T infrm the readers f the basic knwledge abut the black hle,
C．T share with the readers the new develpment f the black hle discvery,
D．T demnstrate the significance f discvering new black hles fr science.
22．Which f the fllwing abut LB-1 is true t the passage?
A．It is the biggest black hle ever discvered,
B．It lst nly a small part f its mass thrugh explsin.
C．It culdn't have been frmed frm the cllapse f ne star,
D．Its discvery may lead t sme breakthrugh in the “fallback frmatin thery".
23．Which f the fllwing is right accrding t the passage?
A．If the sun in ur galaxy dies sme f its mass will be taken away by stellar winds.
B．A massive supernva will be frmed and then explded if the sun in ur galaxy dies.
C．"The Milky Way" was frmed after a supermassive black hle cllapsed and explded.
D．If “the Milky Way" dies, a supermassive black hle will be frmed after its death.

Plants d nt listen t the radi. But a team f researchers in Greece recently fund a way t turn lemns int very small “radi statins” that can bradcast infrmatin abut their trees’ misture cntent t a smartphne—the first step tward creating what the researchers call an “Internet f plants.”
Scientists had previusly attached sensrs t trees t measure their water use, but “n ther team had created a wireless radi netwrk amng plants, sending infrmatin while cnsuming nly a few micrwatts and csting just a few dllars,” says prject leader Aggels Bletsas, a prfessr f electrical and cmputer engineering at the Technical University f Crete.
The netwrk cnsists f several basic cmpnents: an existing FM radi statin, an antenna (天线) attached t a lemn grwing n a tree, a humidity (湿度) sensr in the lemn, a transistr cnnected t an antenna and an FM receiver. First, the antenna picks up the signal frm the FM statin, and then passes the signal t the transistr, which is mdulated by the humidity sensr. The sensr switches the transistr n and ff at a rate dependent n the plant’s misture level: if the sil is wet r if the atmsphere is humid, that rate is lwer; if it is dry, the rate is higher. Finally, the antenna bradcasts this infrmatin t the radi receiver n a mbile phne.
In this way, plants can tell farmers if they are thirsty. “We can literally ‘listen’ t the misture f the plant, using ur mbile FM radi with a $3.4 sensr,” Bletsas says. “Tw f these sensrs fr every acre n any given farm might change the way we cnduct agriculture and ‘understand’ plants.” He ntes that mre sensrs may be needed fr the best pssible results. Such real-time infrmatin culd enable better cntrl f air and sil misture.
Why g thrugh all this truble and nt just use already cmmn wireless technlgy, such as Bluetth? “Nt nly is ur technique less cmplex, as we are just brrwing signals in the envirnment,” Bletsas says, but “a Bluetth-based sensr csts abut $25. Our final aim is t launch sensrs nt the market csting less than $1.”
“Bletsas and his team are cmpletely changing the way f envirnmental sensing using very simple equipment and surprisingly little pwer,” says Alexandrs Dimakis, an assciate prfessr f electrical and cmputer engineering at the University f Texas at Austin, wh was nt invlved in the research. “Their wrk culd be a transfrmatinal Internet f Things technlgy fr agriculture and fr mnitring the envirnment.”
Bletsas and his clleagues have already applied fr a patent fr their innvative technlgy in America.

They may have extra skills, and be n hand t help ut with the day-t-day prblems. And an alternate pint f view may help t braden yur mind and aid the risk f mistakes being verlked.
Everybdy knws Samsung’s Galaxy Nte 7.When the phne was launched in 2016,custmers praised it fr its strage, design and usability, and it may well have been a hit if it weren’t fr the fact that it ccasinally caught fire and explded. It was sn banned immediately frm flights, and Samsung had n chice but t recall the entire mdel. The shrtcming reprtedly cst the cmpany $1 billin, and a further $17 billin in lst sales. But remember, based n the lessn, the Galaxy Nte 8 and the Galaxy Nte 9 are well received in the wrld! Nw we knw that failing is part f business success.
One thing that all great cmpanies have in cmmn is that they have failed many times—and luckily, they bunced back. Take Sarah Blakely, funder f shapewear brand Spanx fr example. She credits her business success specifically t her failures. “I’d get kicked ut f buildings all day lng, “she remembered. “Peple wuld tear up my business card in my face. But my friends and I knew I culd sell and I knew I wanted t sell smething I had created. I learned that ‘n’ desn’t always mean ‘n’ ,and that yu may get 30 ns befre yu get the ne yes. Peple tld me n with Spanx fr tw years. “Spanx is wrth just ver $1 billin—it was a cmpany that Blakely wh tk a degree in a law schl started with just $5 000!
28．What can we learn frm the examples in Paragraph 1?
A．Tw heads are better than ne.B．Cnstant drpping wears the stne.
C．Gd helps thse wh help themselves.D．All things are difficult befre they are easy.
29．Why des the authr mentin Samsung’s Galaxy Nte 7,8 and 9?
A．T suggest custmers shuld fllw the new trends.
B．T prve Samsung is respnsible fr custmers.
C．T shw Samsung paid fr its prduct failure.
D．T explain that failures dn’t spell the end.

Peple wrry that develpments in Artificial Intelligence, r A．I., will bring abut a pint in histry when A．I. vertakes human intelligence, leading t an unimaginable revlutin in human affairs. Or they wnder whether instead f ur cntrlling artificial intelligence, it will cntrl us.
The situatin may nt arise fr hundreds f years t cme, but this desn’t mean we have nthing t wrry abut. On the cntrary, The A．I. prducts that nw exist are imprving faster than mst peple realize and prmise t fundamentally transfrm ur wrld, nt always fr the better. They are nly tls, nt a cmpeting frm f intelligence. But they will reshape what wrk means and hw wealth is created.
Unlike the Industrial Revlutin and the Cmputer Revlutin, the A．I. revlutin is nt taking certain jbs and replacing them with ther jbs. Instead, it is believed t cause a wide - scale eliminatin f jbs -- mstly lwer - paying jbs, but sme higher - paying nes, t.
This transfrmatin will result in enrmus prfits fr the cmpanies that develp A．I., as well as fr the cmpanies that adpt it. We are thus facing tw develpments that d nt sit easily tgether; enrmus wealth cncentrated in relatively few hands and enrmus numbers f peple ut f wrk. What is t be dne?
Part f the answer will invlve educating r retraining peple in tasks A．I. tls aren’t gd at. Artificial intelligence is prly suited fr jbs invlving creativity, planning and “crss - field” thinking. But these skills are typically required by high - paying jbs that may be hard t retrain displaced wrkers t d. Mre prmising are lwer - paying jbs invlving the “peple skills” that A．I. lacks: scial wrkers, barmen, drmen -- prfessins requiring human interactin. But hw many barmen des a sciety really need?
The slutin t the prblem f mass unemplyment will invlve “service jbs f lve.” These are jbs that A．I. cannt d, that sciety needs and that give peple a sense f purpse. Examples include accmpanying an lder persn t visit a dctr, helping at an rphanage and serving as a spnsr at charity rganizatin. The vlunteer service jbs f tday, in ther wrds, may turn int the real jbs f the future.
Other vlunteer jbs may be higher - paying and prfessinal, such as cmpassinate medial service prviders. In all cases, peple will be able t chse t wrk fewer hurs than they d nw.
32．In what aspect is the A．I. revlutin different frm the Industrial r the Cmputer revlutin?
A．The A．I. revlutin will finally becme ne beynd human’s cntrl.
B．A．I. is believed t lead t a pint in histry when it takes ver human intelligence.
C．Higher - paying jbs will take the place f lwer-paying nes in the A．I. revlutin.
D．It may bring abut mass unemplyment t matter hw much emplyees are paid.
33．The underlined wrd “prmising” in paragraph 5 is clsest in meaning t _______.
A．prmtinal B．demanding C．guaranteed D．ptential
34．What des the authr suggest in the face f the A．I. revlutin?
A．It is sensible t encurage peple t take vlunteer jbs.
B．Peple shuld be instructed t d less demanding jbs.
C．The prblem f jb lss can be slved by creating lwer-paying jbs.
D．Jbs requiring knwledge in different fields are suitable fr displaced wrkers.
35．Which f the fllwing may serve as the best title f the passage?
A．The A．I. Revlutin Creates New Jb Opprtunities.
B．Challenges the A．I. Revlutin Brings t Jb Market.
C．A Duble - edged Swrd: the A．I. Revlutin.
D．Interrelatinship between A．I. and Unemplyment.

A
Scientists have discvered a "mnster black hle" s massive that, in thery, it shuldn't exist
It’s a stellar black hle---the type that frms after stars die, cllapse, and explde. Researchers had previusly believed that the size limit was n mre than 20 times the mass f ur sun because 8S these stars die, they lse mst f their mass thrugh explsins that expel matter and gas swept away by stellar winds
This thery has nw been tppled by LB-1, the newly discvered black hle. Lcated abut 15.000 light years away, it has a mass 70 times greater than ur sun, accrding t a press release frm the Chinese Academy f Sciences.
The findings were published by Chinese researchers in the jurnal Nature n Wednesday.
"Black bles f such mass shuld nt even exist in ur galaxy, accrding t mst f the current mdels f stellar evlutin," said Liu Jifeng, head f the team that made the discvery. "LB-1 is twice as massive as what we thught pssible. Nw therists will have t take up the challenge f explaining its frmatin."
Scientists are nw scratching their heads at hw LB-1 gt s huge.
The Chinese team has prpsed a number f theries. LB-1' sheer size suggests that it “was nt frmed frm the cllapse f nly ne star," the study said--- instead, it culd ptentially be tw smaller black hles rbiting each ther.
Anther pssibility is that it frmed frm “fallback supermva.” This is when a supernma---the last stage f an explding star---ejects material during the explsin, which then falls back int the supernva, creating a black hle.
This fallback frmatin is theretically pssible, but scientists have never been able t prve r bserve it. If this is hw LB-1 frmed, then we may have "direct evidence fr this prcess” fr the first time, the study said.
There are several types f black hles and stellar black hles like LB-1 are n the smaller side, accrding t NASA．Supermassive black hles are much bigger---they can be billins f times the mass f ur sun,
Scientists believe supermassive black hles may be cnnected t the frmatin f galaxies, as they ften exist at the center f the mass star stems but it is still nt clear exactly hw, r which frm first.

Plants d nt listen t the radi. But a team f researchers in Greece recently fund a way t turn lemns int very small “radi statins” that can bradcast infrmatin abut their trees’ misture cntent t a smartphne—the first step tward creating what the researchers call an “Internet f plants.”
Scientists had previusly attached sensrs t trees t measure their water use, but “n ther team had created a wireless radi netwrk amng plants, sending infrmatin while cnsuming nly a few micrwatts and csting just a few dllars,” says prject leader Aggels Bletsas, a prfessr f electrical and cmputer engineering at the Technical University f Crete.
The netwrk cnsists f several basic cmpnents: an existing FM radi statin, an antenna (天线) attached t a lemn grwing n a tree, a humidity (湿度) sensr in the lemn, a transistr cnnected t an antenna and an FM receiver. First, the antenna picks up the signal frm the FM statin, and then passes the signal t the transistr, which is mdulated by the humidity sensr. The sensr switches the transistr n and ff at a rate dependent n the plant’s misture level: if the sil is wet r if the atmsphere is humid, that rate is lwer; if it is dry, the rate is higher. Finally, the antenna bradcasts this infrmatin t the radi receiver n a mbile phne.
In this way, plants can tell farmers if they are thirsty. “We can literally ‘listen’ t the misture f the plant, using ur mbile FM radi with a $3.4 sensr,” Bletsas says. “Tw f these sensrs fr every acre n any given farm might change the way we cnduct agriculture and ‘understand’ plants.” He ntes that mre sensrs may be needed fr the best pssible results. Such real-time infrmatin culd enable better cntrl f air and sil misture.
Why g thrugh all this truble and nt just use already cmmn wireless technlgy, such as Bluetth? “Nt nly is ur technique less cmplex, as we are just brrwing signals in the envirnment,” Bletsas says, but “a Bluetth-based sensr csts abut $25. Our final aim is t launch sensrs nt the market csting less than $1.”
“Bletsas and his team are cmpletely changing the way f envirnmental sensing using very simple equipment and surprisingly little pwer,” says Alexandrs Dimakis, an assciate prfessr f electrical and cmputer engineering at the University f Texas at Austin, wh was nt invlved in the research. “Their wrk culd be a transfrmatinal Internet f Things technlgy fr agriculture and fr mnitring the envirnment.”
Bletsas and his clleagues have already applied fr a patent fr their innvative technlgy in America.

Everybdy knws Samsung’s Galaxy Nte 7.When the phne was launched in 2016,custmers praised it fr its strage, design and usability, and it may well have been a hit if it weren’t fr the fact that it ccasinally caught fire and explded. It was sn banned immediately frm flights, and Samsung had n chice but t recall the entire mdel. The shrtcming reprtedly cst the cmpany $1 billin, and a further $17 billin in lst sales. But remember, based n the lessn, the Galaxy Nte 8 and the Galaxy Nte 9 are well received in the wrld! Nw we knw that failing is part f business success.
One thing that all great cmpanies have in cmmn is that they have failed many times—and luckily, they bunced back. Take Sarah Blakely, funder f shapewear brand Spanx fr example. She credits her business success specifically t her failures. “I’d get kicked ut f buildings all day lng, “she remembered. “Peple wuld tear up my business card in my face. But my friends and I knew I culd sell and I knew I wanted t sell smething I had created. I learned that ‘n’ desn’t always mean ‘n’ ,and that yu may get 30 ns befre yu get the ne yes. Peple tld me n with Spanx fr tw years. “Spanx is wrth just ver $1 billin—it was a cmpany that Blakely wh tk a degree in a law schl started with just $5 000!

Peple wrry that develpments in Artificial Intelligence, r A．I., will bring abut a pint in histry when A．I. vertakes human intelligence, leading t an unimaginable revlutin in human affairs. Or they wnder whether instead f ur cntrlling artificial intelligence, it will cntrl us.
The situatin may nt arise fr hundreds f years t cme, but this desn’t mean we have nthing t wrry abut. On the cntrary, The A．I. prducts that nw exist are imprving faster than mst peple realize and prmise t fundamentally transfrm ur wrld, nt always fr the better. They are nly tls, nt a cmpeting frm f intelligence. But they will reshape what wrk means and hw wealth is created.
Unlike the Industrial Revlutin and the Cmputer Revlutin, the A．I. revlutin is nt taking certain jbs and replacing them with ther jbs. Instead, it is believed t cause a wide - scale eliminatin f jbs -- mstly lwer - paying jbs, but sme higher - paying nes, t.
This transfrmatin will result in enrmus prfits fr the cmpanies that develp A．I., as well as fr the cmpanies that adpt it. We are thus facing tw develpments that d nt sit easily tgether; enrmus wealth cncentrated in relatively few hands and enrmus numbers f peple ut f wrk. What is t be dne?
Part f the answer will invlve educating r retraining peple in tasks A．I. tls aren’t gd at. Artificial intelligence is prly suited fr jbs invlving creativity, planning and “crss - field” thinking. But these skills are typically required by high - paying jbs that may be hard t retrain displaced wrkers t d. Mre prmising are lwer - paying jbs invlving the “peple skills” that A．I. lacks: scial wrkers, barmen, drmen -- prfessins requiring human interactin. But hw many barmen des a sciety really need?
The slutin t the prblem f mass unemplyment will invlve “service jbs f lve.” These are jbs that A．I. cannt d, that sciety needs and that give peple a sense f purpse. Examples include accmpanying an lder persn t visit a dctr, helping at an rphanage and serving as a spnsr at charity rganizatin. The vlunteer service jbs f tday, in ther wrds, may turn int the real jbs f the future.
Other vlunteer jbs may be higher - paying and prfessinal, such as cmpassinate medial service prviders. In all cases, peple will be able t chse t wrk fewer hurs than they d nw.
32．In what aspect is the A．I. revlutin different frm the Industrial r the Cmputer revlutin?
A．The A．I. revlutin will finally becme ne beynd human’s cntrl.
B．A．I. is believed t lead t a pint in histry when it takes ver human intelligence.
C．Higher - paying jbs will take the place f lwer-paying nes in the A．I. revlutin.
D．It may bring abut mass unemplyment t matter hw much emplyees are paid.
33．The underlined wrd “prmising” in paragraph 5 is clsest in meaning t _______.
A．prmtinal B．demanding C．guaranteed D．ptential
34．What des the authr suggest in the face f the A．I. revlutin?
A．It is sensible t encurage peple t take vlunteer jbs.
B．Peple shuld be instructed t d less demanding jbs.
C．The prblem f jb lss can be slved by creating lwer-paying jbs.
D．Jbs requiring knwledge in different fields are suitable fr displaced wrkers.
35．Which f the fllwing may serve as the best title f the passage?
A．The A．I. Revlutin Creates New Jb Opprtunities.
B．Challenges the A．I. Revlutin Brings t Jb Market.
C．A Duble - edged Swrd: the A．I. Revlutin.
D．Interrelatinship between A．I. and Unemplyment.
