Passage1
(2023四川成都外国语学校3月模拟)
Imagine driving behind a huge truck shting cluds f smke int the air while yur new fully electric vehicle cleans up its carbn emissins.This dream may sn be a reality.A team f students in the Netherlands have created an electric car that nt nly desn’t prduce carbn dixide when driving,but actually pulls it ut f the air.
The tw-seater sprts car was designed and built in less than a year by a team f 32 students at Eindhven University f Technlgy.Called “ZEM”,which stands fr “zer emissin mbility”,the car is equipped with special devices that remve carbn dixide frm the air as it drives.The team says if ZEM is driven abut 32,000 kilmeters,it can remve 2 kilgrams f carbn dixide frm the air.That’s nt a huge amunt.The team calculates that 10 ZEM cars n the rad fr a year wuld remve as much carbn dixide as a typical tree des during that time.Hwever,they als pint ut that there are ver a billin passenger cars in the wrld that culd be using this technlgy.And if a billin cars were remving carbn dixide instead f prducing it,the result wuld be huge.
ZEM als has several ther innvatins that help t make it mre capable f being sustained:the car’s frame and panels(面板) are 3D printed t reduce waste;it was built using recycled and recyclable materials;and it can be easily taken apart s that many f its parts can be reused.ZEM’s battery is als reusable,and has anther handy feature:it can be charged with slar panels n the car’s rf—and can even be used t prvide pwer fr yur huse when the car isn’t n the rad.
Accrding t the statistics,transprtatin was respnsible fr ver 20% f glbal carbn dixide emissins in 2020—and f thse emissins,cars were respnsible fr 41%.The Eindhven team says its gal is t challenge the electric car industry:If 32 students can build a car like this in less than a year,then surely car manufacturers are expected t adpt these innvatins,t.
1.What is special abut ZEM?
A.It can end the wrld’s CO2 release.
B.It can cut the truck’s CO2 emissins.
C.It can reduce the level f CO2 in the air.
D.It can absrb dirty air as well as CO2.
2.Why des the team run the calculatin f ZEM in paragraph 2?
A.T demnstrate a superb visin f ZEM cars.
B.T explain hw ZEM remves CO2 as trees d.

There is nthing quite like enjying the sights,sunds and culture f a city while tasting a cup f cffee utdrs.But it is nt that enjyable when heat waves sweep the city.An utdr cling system prduced by Kinnk,an Israeli (以色列的) cmpany,began t be tested in Tel Aviv.The sweltering city is a perfect place t try the new technlgy.
With glbal warming heating up the temperature,it will sn be t ht t sit utside in cafes.While utdr cling systems have existed fr a while,mst f them use sme srt f water r misting system t cl the air arund them,cnsuming t much water and pwer.After tw years f develpment,the perfect slutin t the prblem was fund.“We have invented a new generatin f air cnditiner,” Kinnk CEO Leizer said.
As Leizer intrduced,the energy is frm the pressure created between liquid nitrgen (氮) and gas nitrgen.When liquid nitrgen at -196 degrees turns int gas,it prduces a very strng pressure and the pressure is used t run a mechanical engine.It is that mechanical engine that slwly releases freezing nitrgen gas t cl dwn the air arund it.
The technlgy is unique and amazing.Beynd the clness f the cncept,it als has ther advantages.The wrk unit desn’t need t be pwer-driven,and desn’t blw ut harmful warm air as it wrks.As fr the ptential price,it will prbably be n mre expensive than any ther air cnditiner.In additin,the liquid nitrgen cntainer will need t be replaced every seven t ten days,depending n usage.This makes it an affrdable ptin fr all srts f businesses.The cling system is expected t be n the market in 2024.
5.What des the underlined wrd “sweltering” mean in paragraph 1?
A.Warm.B.Dry.
C.Ht.D.Freezing.
6.What prblem des the existing utdr cling systems have?
A.They are wasteful.
B.They verheat easily.
C.They ften break dwn.
D.They are slw t cl the air.
7.What des paragraph 3 mainly explain?
A.What pwers the engine.
B.What turns liquid int gas.
C.Hw the pressure is frmed.
D.Hw the new system wrks.
8.What is the purpse f this text?
A.T prmte a cmpany.
B.T settle an energy crisis.
C.T intrduce a technlgy.
D.T market a misting system.
