2.直接解题：

1.WhichofIh6「oI]owing（卜'歹ij的，J1次的）statements（陈述）doesnotindicate

（显示，指出）theimportance（重要性）ofwindowsas（如同）described（被描述）

inthefirst（第一的，最初的）twoparagraphs（段落）？

A）Windowscanchange（变化）fromclear（清晰的）todark（暗的，黑色的）tosave

（节约）energy（能量,活力）.

B）Windowshelptosaveenergybylettinglight（光，灯）ni（让...进入）.

C）Windowshelptosaveenergybyproviding（提供）heat（热，加热）.

D）Windowsenable（使能够）peopletohavecontactwith（与...有接触/联系）the

outside（外面的，外面）world（世界）.

1.A.三个被选项均提到了节约能量，因此首先关注前两个段落中涉及到节约能量的句子，

利用被选项中的细节信息结构（A：fromcleartodark,B:light;C:heat;D:theoutside

world）共同作为答案线索，在文章中查找答案相关句：

Windowsnolonly（不但...而目....）leilight（光）inloculdown（砍倒，减

少）anelectricity（电）use（使用）forlighting（照明），butthelightcorning

through（通过）thewindowalsoprovides（提供）heat（热）,However,windowsare

notsomethingpeopletypicallyassociatewithbeingacuttingedge1technology.

Researchers（彳讲究者）arenowwonb力gm（继续研究，设法说月艮）newtechnologies

whatawindowreallyis,“saysClaesGranqvist.He'saprofessorofsolid-state

physicsatUppsalaUniversityinSweden'."It'scontact（接触）withtheoutside

world.Youhavetohavevisualcontactwiththesurroundingworldtofeelwell.”

So,windowsandnaturallightareimportantforimprovingthewaypeoplefeelwhen

they'restuckindoors.

第一段中的答案相关句说：窗户因为让阳光进入房间，并且为房间提供热源，所以节约了能

源。第二段中的答案相关句说：窗户使人们能接触外部世界。所以B、C和D都说明了

窗户的重要性。所以A是错误的说法。

2.Whenarewindowstheweak（弱的，无力的）link（联系，连接，连接物）inabuilding

（建筑物）？

A）Inthecold（寒冷的）winter（冬季）.

B）Inthehot（热的）summer（夏季）.

C）Whenairconditioners（空调）/rolui、nodon（打开）.

D）BothAandB.

2.D.细节题。利用被选项中的细节信息词（A：coldwinter;B:hotsummer;C:air

conditioners）作为答案线索，在文章中查找答案相关句：顺着上一题的答案位置往下查找

答案相关句：

（第——题答案相关句）Windowsnotonlyletlightintocutdownanelectricity

useforlighting,butthelightcomingthroughthewindowalsoprovidesheat.However,

windowsarenotsomethingpeopletypicallyassociatewithbeingacuttingedge1

technology.（第一题答案相关句）Researchersarenowworkingonnewtechnologiesthat

enableawindowtoquicklychangefromcleartodarkandanywhereinbetweenwith

a「lipof'上switch".

“Ittookusalongtimetofigureoutwhatawindowreallyis,“saysClaes

Granqvist.He'saprofessorofsolid-statephysicsatUppsalaUniversityinSweden3.

（第一题答案相关句）"II'$c/onlac-lwithihooi心idoworld.Youhavetohavevisual

areimportantforimprovingthewaypeoplefeelwhenthey'restuckindoors.

（第3段）Yet,windowsar。theweaklink（问逊句中的核心词）inabuildingwhon

itcomesto（当提至.）energy（能量）andtemperature（温度）control（控制，管

理）.Inthewinter,coldair（空气）leaks（渗透，漏）in.Whenit'shotandsunny

（阳光充足的），sunlight（阳光）stroams（流淌，溪，河流）in.Allofthissunlight

carrieslotsofheatandenergy.Andallofthisextraheatforcespeopletoturn

ontheirairconditioners.Producingblastsofcoldair,whichcanfeelsorefreshing,

actuallysuckupenormousamountsofelectricityinbuildingsaroundtheworld.

短文第三段的第一句说：windowsaretheweaklinkinabuilding,接下来是对这句话

分寒冬和炎夏做了说明。所以D是正确选择。

3.Whataresmartwindows,accordingto（根据）Paragraph4?

A）Windowsthatarccoated（被涂层的）.

B）Windowsthatareglazed（被装了窗户的，被上了釉的）.

C）Windowsthecolorofwhichcanbechanged.

D）Windowsthathavemanylayers（有许多层的）.

3.C.细节题。利用被选项中的核心词及细节信息词（A:coat;B:glaze;C:change;D:

manylayers）共同作为答案线索，在文章中查找答案相关句:

Windowsnotonlylet1ightintocutdownanelectricityusefor1ighting,but

thelightcomingthroughthewindowalsoprovidesheat.However,windowsarenot

somethingpeopletypicallyassociatewithbeingacuttingedge1technology.

Researchersarenowworkingonnewtechnologiesthatenableawindowtoquickly

changefromcleartodarkandanywhereinbetweenwithaflipofaswitch2.

“Ittookusalongtimetofigureoutwhatawindowreallyis,“saysClaes

Granqvist.He'saprofessorofsolid-statephysicsatUppsalaUniversityinSweden3.

“It'scontactwiththeoutsideworld.Youhavetohavevisualcontactwiththe

surroundingworldtofeelwell."So,windowsandnaturallightareimportantfor

improvingthewaypeoplefeelwhenthey'restuckindoors.

（第2题答案相关句）Yet,windowsaretheweaklinkinabuildingwhenitcomes

（第4段）Windowshavebeenamajorfocusofenergyresearchforalongtime.Over

theyears,scientistshavecomeupwithavarietyofstrategiesforcoating（对

应选项A中的coat）,glazing（对应选项B中的glaze）,andlayering（对应选项D中

的layer）windowstomakethemmoreenergyefficient.Smarlwindowsgoastepfurther.

Theyuse（使用）chromogenic（发色的）technologies（技术）whichinvolve（包括）

changesofcolor.

第四段告诉我们，多年来，科学家已研究出多种通过窗户节能的办法，而smartwindows

使用的技术使窗户能变换颜色。所以C是正确选择。

4.Tomakeelectrochromic（电致变色的）windowschangecolor,whatisappliedto

（被用于）thewindowglass（玻璃，玻璃杯，眼镜）？

A）Electricity（电,电流）.

B）Tungstenoxide（氧化鸨）.

C）Abattery（电池）.

D）Avoltage（电压）.

4.B.细节题。利用问题句中的细节信息结构（electrochromicwindows,windowglass）

及被选项中的细节信息结构（黑体结构）共同作为答案线索，在文章中查找答案相关句：

Windowsnotonlylet1ightintocutdownanelectricityusefor1ighting,but

thelightcomingthroughthewindowalsoprovidesheat.However,windowsarenot

andlayeringwindowstomakethemmoreenergyefficient.（答案相关句）Sniarlwindows

goastepfurther.Theyusechromogenictechnologieswhichinvolvechangesofcolor.

（第5段）Electrochromicwindows（电致变色的）useelectricitytochangecolor.

Forexample（例如）,asheetof（——片）glasscoatedwiththin（薄薄的）layersof

chomical（化学的）compound（混合物）such8s（例如）tungstenoxide（氧化鸨）works

（「作）abit（二点:/少许）liko（象）abattery（电池）.Tungstenoxideisclear

whentheamountofvoltageisdecreased,thewindowdarkensuntilit'scompletely

darkafteral1electricityistakenaway.Soapplyingavoltagedetermineswhether

thewindowlooksclearordark.

第五段第二句提供了答案。asheetofglasscoatedwiththinlayersofchemicalcompound

suchastungstenoxide中的coated是“涂上一层薄薄的...”的意思。

5.Whatwillbethebenefit（利益，好处）iftheresearchon（关于）smartwindows

lurnsoutlobe（结果证明）successful（成功的），accordingto（根据）thelast
