2025年成考專升本英語試題及答案解析詞匯與語法結(jié)構(gòu)（共15小題；每小題1分，共15分）從每小題的四個(gè)選擇項(xiàng)中，選出最佳的一項(xiàng)。1.Thenewhospitalisreported____lastmonth.A.tohavebeencompletedB.tobecompletedC.havingbeencompletedD.havingcompleted答案：A解析：本題考查非謂語動詞?！癰ereportedtodosth.”是固定用法，表示“據(jù)報(bào)道做某事”。根據(jù)時(shí)間狀語“l(fā)astmonth”可知，醫(yī)院是在過去已經(jīng)被建成，所以要用完成式的被動語態(tài)“tohavebeencompleted”。選項(xiàng)B是一般式的被動，不能體現(xiàn)動作的完成；選項(xiàng)C和D的形式不符合“bereportedtodo”的結(jié)構(gòu)。2.Sheistheonlyoneofthegirlswho____passedtheexam.A.haveB.hasC.areD.is答案：B解析：本題考查定語從句中主謂一致。在“oneof+復(fù)數(shù)名詞+定語從句”結(jié)構(gòu)中，如果one前有theonly等限定詞修飾，定語從句的謂語動詞要用單數(shù)形式。本句中先行詞是“theonlyone”，所以定語從句的謂語要用第三人稱單數(shù)形式“has”。選項(xiàng)A是復(fù)數(shù)形式；選項(xiàng)C和D不符合定語從句表達(dá)“已經(jīng)通過考試”的語境。3.Itwasnotuntilmidnight____theyreachedthecampsite.A.thatB.whenC.whileD.as答案：A解析：本題考查強(qiáng)調(diào)句。強(qiáng)調(diào)句的基本結(jié)構(gòu)是“Itis/was+被強(qiáng)調(diào)部分+that/who+其他部分”。本句強(qiáng)調(diào)的是時(shí)間狀語“notuntilmidnight”，所以要用“that”引導(dǎo)。選項(xiàng)B“when”用于引導(dǎo)時(shí)間狀語從句；選項(xiàng)C“while”表示“當(dāng)……時(shí)候”，強(qiáng)調(diào)兩個(gè)動作同時(shí)進(jìn)行；選項(xiàng)D“as”可表示“當(dāng)……時(shí)候”“因?yàn)椤薄半S著”等含義，均不符合強(qiáng)調(diào)句的結(jié)構(gòu)。4.____,healwaystrieshisbesttocompleteitontime.A.HoweverthetaskishardB.HoweverhardthetaskisC.ThoughhardthetaskisD.Thoughthetaskishard答案：B解析：本題考查讓步狀語從句?！癶owever”引導(dǎo)讓步狀語從句時(shí)，結(jié)構(gòu)是“however+形容詞/副詞+主語+謂語”。選項(xiàng)A語序錯誤；選項(xiàng)C“though”引導(dǎo)讓步狀語從句時(shí)，正確的語序應(yīng)該是“Thoughthetaskishard”，“Though”引導(dǎo)讓步狀語從句時(shí)一般不用倒裝；選項(xiàng)D雖然表達(dá)正確，但“however”引導(dǎo)的讓步狀語從句語氣更強(qiáng)，更符合語境。5.Hehasmadeanotherwonderfuldiscovery,____ofgreatimportancetoscience.A.whichIthinkisB.whichIthinkitisC.IthinkwhichisD.ofwhichIthinkitis答案：A解析：本題考查非限定性定語從句?！皐hich”引導(dǎo)非限定性定語從句，在從句中作主語，“Ithink”是插入語，不影響句子結(jié)構(gòu)。選項(xiàng)B中“it”多余，因?yàn)椤皐hich”在從句中已經(jīng)作了主語；選項(xiàng)C定語從句的引導(dǎo)詞“which”應(yīng)放在句首；選項(xiàng)D結(jié)構(gòu)錯誤。6.Idon'tthinkitadvisablethatTom____tothejobsincehehasnoexperience.A.isassignedB.willbeassignedC.beassignedD.hasbeenassigned答案：C解析：本題考查虛擬語氣。在“itisadvisable/necessary/important等+that從句”結(jié)構(gòu)中，從句要用虛擬語氣，即“should+動詞原形”，“should”可以省略。本句中“Tom”和“assign”之間是被動關(guān)系，所以要用“beassigned”。選項(xiàng)A是一般現(xiàn)在時(shí)的被動語態(tài)；選項(xiàng)B是一般將來時(shí)的被動語態(tài)；選項(xiàng)D是現(xiàn)在完成時(shí)的被動語態(tài)，均不符合虛擬語氣的要求。7.Themanagerpromisedtokeepme____ofhowourbusinesswasgoingon.A.informedB.informingC.toinformD.havinginformed答案：A解析：本題考查非謂語動詞作賓語補(bǔ)足語。“keepsb.informedofsth.”是固定用法，表示“讓某人了解某事”，“informed”是過去分詞作賓語補(bǔ)足語，與“me”之間是被動關(guān)系，即“我被告知”。選項(xiàng)B“informing”是現(xiàn)在分詞，表主動和進(jìn)行；選項(xiàng)C“toinform”是動詞不定式；選項(xiàng)D“havinginformed”是現(xiàn)在分詞的完成式，均不符合“keepsb.informedofsth.”的結(jié)構(gòu)。8.Theproblem____atthemeetingtomorrowisveryimportant.A.discussedB.tobediscussedC.beingdiscussedD.havingbeendiscussed答案：B解析：本題考查非謂語動詞作后置定語。根據(jù)時(shí)間狀語“tomorrow”可知，問題是將來要被討論，所以要用動詞不定式的被動式“tobediscussed”作后置定語。選項(xiàng)A“discussed”表示過去分詞作后置定語，表被動和完成；選項(xiàng)C“beingdiscussed”表示正在被討論；選項(xiàng)D“havingbeendiscussed”表示已經(jīng)被討論，均不符合“tomorrow”這個(gè)時(shí)間要求。9.NeitherJohnnorhisparents____athome.A.isB.areC.hasD.was答案：B解析：本題考查主謂一致。“neither...nor...”連接兩個(gè)主語時(shí)，謂語動詞要與靠近它的主語保持一致，本句中靠近謂語的主語是“hisparents”，是復(fù)數(shù)，所以謂語要用復(fù)數(shù)形式“are”。選項(xiàng)A是單數(shù)形式；選項(xiàng)C“has”作為助動詞時(shí)，常與過去分詞構(gòu)成完成時(shí)態(tài)，作為實(shí)義動詞表示“有”等含義，不符合語境；選項(xiàng)D“was”是單數(shù)形式的過去式。10.Ican'tstand____withJaneinthesameoffice.Shejustrefuses____talkingwhilesheworks.A.working;stoppingB.towork;stoppingC.working;tostopD.towork;tostop答案：C解析：本題考查非謂語動詞?！癱an'tstanddoingsth.”表示“不能忍受做某事”，所以第一個(gè)空要用“working”；“refusetodosth.”表示“拒絕做某事”，所以第二個(gè)空要用“tostop”。選項(xiàng)A中“stopping”不符合“refusetodosth.”的結(jié)構(gòu)；選項(xiàng)B“towork”不符合“can'tstanddoingsth.”的結(jié)構(gòu)；選項(xiàng)D兩個(gè)空的形式都錯誤。11.Theyoungmanisveryexcellent.Nowheisthe____ofabigcompany.A.directorB.doctorC.dancerD.driver答案：A解析：本題考查詞匯辨析。根據(jù)“abigcompany”可知，這里需要一個(gè)與公司職位相關(guān)的詞匯。選項(xiàng)A“director”表示“董事、經(jīng)理、主管”，符合語境；選項(xiàng)B“doctor”是“醫(yī)生”；選項(xiàng)C“dancer”是“舞者”；選項(xiàng)D“driver”是“司機(jī)”，均不符合在大公司工作的語境。12.Thehouseneeds____,buttheyplantowaituntilnextspringtodoit.A.paintB.topaintC.paintingD.beingpainted答案：C解析：本題考查“need”的用法?！皀eed”作為實(shí)義動詞時(shí)，有兩種用法：“needtodosth.”表示“需要做某事”，主語是人；“needdoing”表示“需要被做”，主語是物，此時(shí)“needdoing”相當(dāng)于“needtobedone”。本句主語是“thehouse”，所以要用“needpainting”。選項(xiàng)A“paint”是動詞原形；選項(xiàng)B“topaint”不符合“needdoing”的結(jié)構(gòu)；選項(xiàng)D“beingpainted”形式錯誤。13.Theprofessorgaveusmanygoodsuggestionsonhowto____ourtime.A.doB.useC.takeD.make答案：B解析：本題考查詞匯搭配?！皍seone'stime”表示“利用時(shí)間”，符合語境。選項(xiàng)A“do”常見搭配有“doone'shomework”“doajob”等，不能與“time”搭配；選項(xiàng)C“take”常見搭配有“taketime”表示“花費(fèi)時(shí)間”，但“take”與“time”搭配時(shí)不能表達(dá)“利用時(shí)間”的意思；選項(xiàng)D“make”常見搭配有“makeuseoftime”，但這里直接用“maketime”不合適。14.She____herhairstyleinherhometownbeforeshecametoChongqingforabetterjob.A.wouldchangeB.haschangedC.changedD.waschanging答案：C解析：本題考查時(shí)態(tài)。根據(jù)“beforeshecametoChongqing”可知，“改變發(fā)型”這個(gè)動作發(fā)生在過去，所以要用一般過去時(shí)。選項(xiàng)A“wouldchange”表示過去將來時(shí)；選項(xiàng)B“haschanged”是現(xiàn)在完成時(shí)，表示過去發(fā)生的動作對現(xiàn)在造成的影響或結(jié)果；選項(xiàng)D“waschanging”是過去進(jìn)行時(shí)，表示過去某個(gè)時(shí)間正在進(jìn)行的動作，均不符合語境。15.—I'msorryIbroketheglass.—____.A.That'srightB.Itdoesn'tmatterC.NoproblemD.Withpleasure答案：B解析：本題考查日常交際用語。當(dāng)別人為做錯事而道歉時(shí)，應(yīng)該表示原諒。選項(xiàng)A“That'sright”表示“那是對的”；選項(xiàng)B“Itdoesn'tmatter”表示“沒關(guān)系”，符合語境；選項(xiàng)C“Noproblem”通常用于回答別人的請求，表示“沒問題”；選項(xiàng)D“Withpleasure”用于回答別人的請求，表示“樂意效勞”。閱讀理解（共15小題；每小題3分，共45分）閱讀下列短文，然后根據(jù)短文的內(nèi)容從每小題的四個(gè)選擇項(xiàng)中選出最佳的一項(xiàng)。Passage1Inmodernsociety,stressisacommonphenomenon.Peopleofdifferentagesandoccupationsarefacingvariouskindsofstress.Stresscancomefromwork,study,family,andsocialrelationships.Forstudents,thestressmainlycomesfromstudy.Theyhavetodealwithalargenumberofcourses,exams,andassignments.Highpressureexamscanmakethemfeelextremelynervous.Forexample,duringthecollegeentranceexaminationperiod,manystudentssufferfromstressrelatedproblemssuchasinsomniaandlossofappetite.Workersalsohavetheirownstress.Theymayfaceheavyworkloads,tightdeadlines,andintensecompetitionintheworkplace.Asalesman,forinstance,hastomeetthesalestargeteverymonth.Ifhefailstodoso,hemaybecriticizedbyhisbossorevenlosehisjob.Familylifecanalsobeasourceofstress.Maritalproblems,financialdifficulties,andtheresponsibilityoftakingcareofchildrenorelderlyparentscanallputpressureonpeople.Socialrelationshipscanaddtothestressaswell.Peoplemayfeelstressedwhentheyhavetodealwithdifficultpeopleortrytofitinwithanewsocialgroup.However,stressisnotalwaysabadthing.Acertainamountofstresscanbemotivating.Itcanpushpeopletoworkharderandachievebetterresults.Butifthestressistoointenseandlastsforalongtime,itcanhavenegativeeffectsonpeople'sphysicalandmentalhealth.16.Whatisthemainideaofthispassage?A.Stressisacommonphenomenononlyamongstudentsandworkers.B.Stresscomesfromvarioussourcesandhasbothpositiveandnegativeeffects.C.Familylifeisthebiggestsourceofstressforpeople.D.Stressonlyhasnegativeeffectsonpeople'shealth.答案：B解析：本題考查文章主旨。文章開篇指出壓力是現(xiàn)代社會的常見現(xiàn)象，接著分別闡述了壓力來自學(xué)習(xí)、工作、家庭和社會關(guān)系等不同方面，最后說明壓力并非總是壞事，一定的壓力有激勵作用，但過度和長期的壓力會對身心健康有負(fù)面影響。選項(xiàng)A中“onlyamongstudentsandworkers”錯誤，文中提到不同年齡和職業(yè)的人都面臨壓力；選項(xiàng)C“Familylifeisthebiggestsourceofstress”在文中未提及；選項(xiàng)D“onlyhasnegativeeffects”錯誤，文中明確提到壓力有積極作用。17.Accordingtothepassage,whichofthefollowingisNOTasourceofstress?A.Highpressureexamsforstudents.B.Heavyworkloadsforworkers.C.Havingagoodtimewithfriends.D.Maritalproblemsinfamilylife.答案：C解析：本題考查對文章細(xì)節(jié)的理解。文章中提到學(xué)生的壓力來自學(xué)習(xí)，如高壓考試；工人的壓力來自工作，如繁重的工作量；家庭生活中的壓力包括婚姻問題等。選項(xiàng)A、B、D均在文中有提及。而選項(xiàng)C“Havingagoodtimewithfriends”是愉快的社交活動，不會帶來壓力，不符合文章中關(guān)于壓力來源的描述。18.Whatcanwelearnfromthepassageaboutstress?A.Allstressisbadforpeople.B.Stresscan'tmotivatepeopleatall.C.Acertainamountofstresscanmakepeopleworkharder.D.Stressonlyaffectspeople'smentalhealth.答案：C解析：本題考查對文章中關(guān)于壓力影響的理解。文章提到“acertainamountofstresscanbemotivating.Itcanpushpeopletoworkharderandachievebetterresults”。選項(xiàng)A“Allstressisbadforpeople”錯誤，文中明確說明一定壓力有積極作用；選項(xiàng)B“Stresscan'tmotivatepeopleatall”與原文不符；選項(xiàng)D“Stressonlyaffectspeople'smentalhealth”錯誤，文中提到壓力會對人們的身體和心理健康都有影響。19.Whydosalesmenfeelstressedaccordingtothepassage?A.Becausetheyhavetotakecareofelderlyparents.B.Becausetheyhavetomeetthesalestargeteverymonth.C.Becausetheyhavetodealwithalargenumberofcourses.D.Becausetheyhavetofitinwithanewsocialgroup.答案：B解析：本題考查對文章中具體例子的理解。文中提到“Asalesman,forinstance,hastomeetthesalestargeteverymonth.Ifhefailstodoso,hemaybecriticizedbyhisbossorevenlosehisjob”，說明銷售人員感到壓力是因?yàn)槊吭乱瓿射N售目標(biāo)。選項(xiàng)A“takecareofelderlyparents”是家庭方面的壓力；選項(xiàng)C“dealwithalargenumberofcourses”是學(xué)生面臨的壓力；選項(xiàng)D“fitinwithanewsocialgroup”是社交關(guān)系方面的壓力，均不符合銷售人員壓力的來源。20.Whatwillhappenifthestressistoointenseandlastsforalongtime?A.Peoplewillbecomemoremotivated.B.Peoplewillworkevenharder.C.Itwillhavenegativeeffectsonpeople'sphysicalandmentalhealth.D.Itwillhavenoeffectonpeople'slives.答案：C解析：本題考查對文章中關(guān)于過度壓力影響的理解。文章最后提到“Butifthestressistoointenseandlastsforalongtime,itcanhavenegativeeffectsonpeople'sphysicalandmentalhealth”。選項(xiàng)A“becomemoremotivated”和選項(xiàng)B“workevenharder”是一定壓力的積極作用；選項(xiàng)D“havenoeffectonpeople'slives”與原文不符。Passage2TheInternethasbecomeanimportantpartofourlives.Ithaschangedthewaywelive,work,andcommunicate.WiththeInternet,wecanaccessavastamountofinformationinashorttime.Wecansearchforanythingwewanttoknow,fromhistoryandsciencetoentertainmentandfashion.Inadditiontoinformationseeking,theInternetalsoprovidesvariousservices.Wecanshoponline,paybills,booktickets,andeventakeonlinecourses.Onlineshoppinghasbecomeverypopular.Wecancomparepricesandproductsfromdifferentsellerswithoutleavingourhomes.Thissavesustimeandmoney.SocialmediaisanotherimportantaspectoftheInternet.PlatformslikeFacebook,Twitter,andWeChatallowpeopletoconnectwithfriends,family,andevenstrangers.Wecanshareourthoughts,photos,andexperienceswithothers.Socialmediahasmadethewor
