2025全國(guó)英語(yǔ)等級(jí)考試（PETS）四級(jí)試卷：語(yǔ)法知識(shí)鞏固與應(yīng)用試題考試時(shí)間：______分鐘總分：______分姓名：______一、單項(xiàng)選擇這一部分啊，我可得好好給你講講。咱們英語(yǔ)四級(jí)考試?yán)?，單?xiàng)選擇可是個(gè)重頭戲，它主要考察的是你對(duì)英語(yǔ)基礎(chǔ)知識(shí)的掌握程度，尤其是語(yǔ)法這塊兒。我當(dāng)年教學(xué)生的時(shí)候，發(fā)現(xiàn)很多同學(xué)在這塊兒都容易丟分，要么就是模棱兩可，要么就是完全蒙的。所以，這一部分啊，一定要引起重視，不能輕視。我給你出個(gè)例子吧，比如這個(gè)句子："Theboyisenoughsmarttosolvetheproblem."你覺得這句話對(duì)不對(duì)？很多同學(xué)一看，覺得好像沒什么大問題，就選了。但你要是仔細(xì)分析一下，就會(huì)發(fā)現(xiàn)不對(duì)勁。這里的"enough"是副詞，應(yīng)該放在形容詞"smart"的前面，才符合英語(yǔ)的語(yǔ)法規(guī)則。所以，正確的句子應(yīng)該是"Theboyissmartenoughtosolvetheproblem."這個(gè)小細(xì)節(jié)啊，往往就是區(qū)分高分和低分的所在。好了，那現(xiàn)在我就給你出幾道題，你好好做做，看看自己掌握得怎么樣。每一道題都有四個(gè)選項(xiàng)，你只需要選出最符合語(yǔ)法規(guī)則的那個(gè)選項(xiàng)就行。記住，不要緊張，慢慢來，仔細(xì)分析每個(gè)選項(xiàng)的語(yǔ)法結(jié)構(gòu)，相信你一定能做對(duì)的。1.Thecompanyislookingforsomeone______hasgoodcommunicationskills.A)whichB)whoC)thatD)whom2.IfI______you,Iwouldapologizetoher.A)amB)wereC)beD)was3.Sheistheonlyone______canfinishtheprojectontime.A)whoB)thatC)whomD)whose4.Thebook______Iborrowedfromthelibraryisveryinteresting.A)whoB)whichC)thatD)whom5.Nobodyknowstheanswer______.A)whichB)thatC)whatD)whom6.Theman______Ispoketoyesterdayismynewboss.A)whoB)whomC)whoseD)which7.Thisisthepark______weusedtoplaywhenwewerechildren.A)whichB)thatC)whereD)when8.Thegirl______livesnextdoorisafamoussinger.A)whoB)whomC)whoseD)which9.Themovie______wewatchedlastnightwasveryscary.A)whichB)thatC)whoseD)whom10.Theteacher______Ihavealotofrespectforisverypatient.A)whoB)whomC)whoseD)which二、改錯(cuò)題改錯(cuò)題啊，也是咱們英語(yǔ)四級(jí)考試?yán)锏囊淮箅y點(diǎn)，很多同學(xué)一看到這種題就頭疼。其實(shí)啊，改錯(cuò)題也沒那么難，只要你能掌握一定的技巧，就能輕松應(yīng)對(duì)。我給你講講我當(dāng)年是怎么教學(xué)生做改錯(cuò)題的。我一般會(huì)告訴學(xué)生，做改錯(cuò)題的時(shí)候，要逐行看，不要跳過任何一行的任何一個(gè)單詞。因?yàn)橛袝r(shí)候，錯(cuò)誤可能就藏在一個(gè)很小的細(xì)節(jié)里。你還得注意上下文的關(guān)系，有時(shí)候一個(gè)單詞的錯(cuò)誤，可能會(huì)影響到整個(gè)句子的意思。我當(dāng)年有個(gè)學(xué)生，就因?yàn)榘?their"寫成了"there"，結(jié)果整句話的意思就變了，你說逗不逗？好了，那現(xiàn)在我就給你出一篇短文，里面有一些錯(cuò)誤，你需要找出并改正它們。每一行只有一個(gè)錯(cuò)誤，多找或少找都不行。記住，改錯(cuò)題啊，考驗(yàn)的是你的細(xì)心和耐心，一定要認(rèn)真對(duì)待。1.Shedon'thaveacar,sosheusuallygoestoworkbybus.1.______2.IfIhaveenoughmoney,Iwilltravelaroundtheworld.1.______3.Thechildrenareplayinginthegardensinceitisasunnyday.1.______4.Hedidn'tgotothepartybecausehefeltunwell.1.______5.Theyhavelivedinthistownforfiveyears.1.______6.Mysisterisadoctorandsheworksinahospital.1.______7.Wewouldhavegonetotheconcertifwehadknownaboutit.1.______8.Thebookisveryinteresting,itkeepsmereadingallnight.1.______9.Ihavefinishedmyhomework,nowIcanwatchTV.1.______10.Althoughitwasraining,theydecidedtogoforawalk.1.______三、完成句子這一部分啊，我覺得挺有意思的。它不像選擇題那樣有四個(gè)選項(xiàng)給你挑，而是讓你根據(jù)給定的句子開頭或結(jié)尾，補(bǔ)全句子，考察的是你實(shí)際運(yùn)用語(yǔ)法知識(shí)的能力。我當(dāng)年教學(xué)生的時(shí)候，發(fā)現(xiàn)很多同學(xué)在這一塊兒容易犯迷糊，要么就是不知道從哪兒下手，要么就是補(bǔ)的句子語(yǔ)法不對(duì)，意思也跑偏了。所以，這一部分啊，你需要好好思考，不能光靠感覺。我給你舉個(gè)例子吧，比如這個(gè)句子："Althoughheisyoung,______."你覺得應(yīng)該怎么補(bǔ)全？很多同學(xué)可能會(huì)寫"heisverytalented"，但你要是仔細(xì)想想，就會(huì)發(fā)現(xiàn)這個(gè)句子雖然語(yǔ)法沒錯(cuò)，但跟前面的"Althoughheisyoung"搭配起來，意思上就不太連貫。更好的選擇可能是"heknowsalot"，這樣才符合邏輯。這個(gè)例子啊，就是想告訴你，補(bǔ)全句子不光要看語(yǔ)法，還得看意思，得前后呼應(yīng)。好了，那現(xiàn)在我就給你出幾道題，你好好做做，看看自己掌握得怎么樣。每一道題都有兩個(gè)部分，一部分是句子的開頭或結(jié)尾，另一部分是給你的一些提示，你需要根據(jù)這些提示，補(bǔ)全句子。記住，不要緊張，慢慢來，仔細(xì)思考每個(gè)選項(xiàng)的語(yǔ)法和意思，相信你一定能做對(duì)的。1.Shefailedtheexambecause______.a)shedidn’tstudyhardb)shewassickthatdayc)herteacherwasunfaird)shedidn’tunderstandthequestions2.______,Iwouldhavegonetotheparty.a)IfIhadknownaboutitb)IfIknewaboutitc)WhenIknewaboutitd)IfIknowaboutit3.Thebookisveryinteresting,______.a)itkeepsmereadingallnightb)Ithinkit’sboringc)youshouldreadittood)itmakesmesleepy4.Althoughitwasraining,______.a)theydecidedtogoforawalkb)theystayedathomealldayc)theywerehappytoseetheraind)theydidn’tmindtheweather5.Ihavelivedinthistownforfiveyears,______.a)Istilldon’tlikeitb)Imovedherelastyearc)Iwanttomovetoanothercityd)Iloveitmorethananyotherplace6.Hedidn’tgotothepartybecause______.a)hedidn’tlikethemusicb)hehadtoworkc)helosthiswayd)hedidn’twanttogo7.______,shewouldhavepassedtheexam.a)Ifshehadstudiedharderb)Ifshestudiedhardc)Whenshestudiedhardd)Ifshestudieshard8.Thechildrenareplayinginthegardenbecause______.a)itisasunnydayb)theydon’thavehomeworkc)theirparentstoldthemtod)theyareverybored9.Mysisterisadoctor,______.a)sheworksinahospitalb)shedoesn’tlikeherjobc)shewantstobeateacherd)shedoesn’thaveanypatients10.Althoughheisyoung,______.a)heisverytalentedb)heknowsalotc)hedoesn’tunderstandanythingd)heisverylazy四、句子改寫句子改寫啊，也是咱們英語(yǔ)四級(jí)考試?yán)锏囊淮箅y點(diǎn)，很多同學(xué)一看到這種題就頭疼。其實(shí)啊，句子改寫也沒那么難，只要你能掌握一定的技巧，就能輕松應(yīng)對(duì)。我給你講講我當(dāng)年是怎么教學(xué)生做句子改寫題的。我一般會(huì)告訴學(xué)生，做句子改寫題的時(shí)候，要仔細(xì)閱讀原句，理解句子的意思，然后根據(jù)題目要求，用不同的句型或詞匯來表達(dá)相同的意思。改寫的時(shí)候，要注意語(yǔ)法和邏輯的正確性，不能改變?cè)涞囊馑?。我?dāng)年有個(gè)學(xué)生，就因?yàn)楦膶懙臅r(shí)候多加了一個(gè)詞，結(jié)果整句話的意思就變了，你說逗不逗？好了，那現(xiàn)在我就給你出一組句子，你需要根據(jù)題目要求，改寫句子。每一道題都有原句和改寫要求，你需要根據(jù)改寫要求，改寫句子。記住，不要緊張，慢慢來，仔細(xì)思考每個(gè)選項(xiàng)的語(yǔ)法和意思，相信你一定能做對(duì)的。1.Originalsentence:"Sheisa
