高校往年考試題庫及答案一、數(shù)學(xué)學(xué)科（一）選擇題1.函數(shù)\(y=\sinx\)的導(dǎo)數(shù)是（）A.\(\cosx\)B.-\(\cosx\)C.\(\sinx\)D.-\(\sinx\)答案：A2.極限\(\lim_{x\to0}\frac{\sinx}{x}\)的值為（）A.0B.1C.\(\infty\)D.不存在答案：B（二）填空題1.曲線\(y=x^2+1\)在點(diǎn)\((1,2)\)處的切線方程為______。答案：\(y-2=2(x-1)\)，即\(2x-y=0\)2.\(\intx^2dx=\)______。答案：\(\frac{1}{3}x^3+C\)（\(C\)為常數(shù)）（三）解答題1.求函數(shù)\(f(x)=x^3-3x^2+1\)的單調(diào)區(qū)間和極值。解：首先求導(dǎo)\(f^\prime(x)=3x^2-6x=3x(x-2)\)。令\(f^\prime(x)=0\)，即\(3x(x-2)=0\)，解得\(x=0\)或\(x=2\)。當(dāng)\(x\lt0\)時(shí)，\(f^\prime(x)\gt0\)，函數(shù)\(f(x)\)單調(diào)遞增；當(dāng)\(0\ltx\lt2\)時(shí)，\(f^\prime(x)\lt0\)，函數(shù)\(f(x)\)單調(diào)遞減；當(dāng)\(x\gt2\)時(shí)，\(f^\prime(x)\gt0\)，函數(shù)\(f(x)\)單調(diào)遞增。所以函數(shù)\(f(x)\)的單調(diào)遞增區(qū)間為\((-\infty,0)\)和\((2,+\infty)\)，單調(diào)遞減區(qū)間為\((0,2)\)。極大值為\(f(0)=1\)，極小值為\(f(2)=2^3-3\times2^2+1=-3\)。二、英語學(xué)科（一）單項(xiàng)選擇題1.-______youcometomypartytomorrowevening?-I'mafraidIcan't.Ihavetolookaftermysister.A.CanB.MustC.ShouldD.Need答案：A2.Thebook______beTom's.Look!Hisnameisonthecover.A.mustB.mayC.can'tD.needn't答案：A（二）閱讀理解閱讀下列短文，從每題所給的A、B、C、D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。Passage1WhenIwasachild,Iusedtolovewalkinginthewoodsaroundmyhome.Mymomusedtotellmestoriesabouttheanimalsthatlivedthere.Oneday,IwaswalkingalonewhenIsawabeautifulbird.Ithadbrightcolorsandalongtail.Iwassoexcitedandfolloweditforalongtime.Suddenly,itflewintoathickbush.Itriedtolookforitbutcouldn'tfindit.Thatday,Irealizedhowwonderfulnatureis.1.Whatdidthewriterusetolovedoingwhenhewasachild?A.Playingwithanimals.B.Walkinginthewoods.C.Listeningtostories.D.Drawingpicturesofbirds.答案：B2.Whydidthewriterfollowthebird?A.Becausehewantedtocatchit.B.Becausehewasattractedbyit.C.Becausehewantedtotakeaphotoofit.D.Becausehewantedtostudyit.答案：B（三）寫作假設(shè)你是李華，你的英國朋友Tom來信詢問你學(xué)校的課外活動情況，請你給他寫一封回信，介紹學(xué)校的一些主要課外活動以及你喜歡的活動和原因。DearTom,I'mverygladtohearfromyou.Youaskedabouttheextracurricularactivitiesinourschoolinyourletter.NowI'dliketotellyousomethingaboutthem.Thereareallkindsofextracurricularactivitiesinourschool.Wehaveareadingclubwherestudentscanexchangetheirideasaboutdifferentbooks.Thereisalsoasportsclubwithvarioussportslikebasketball,footballandtennis.Andwehaveanartclubforthosewhoareinterestedinpaintinganddrawing.Amongtheseactivities,Ilikethereadingclubbest.ThereasonisthatIcangainalotofknowledgefromdifferentbooks.Bydiscussingwithotherclubmembers,Icanalsoimprovemythinkingabilityandcommunicationskills.Itreallybroadensmyhorizons.Whatabouttheextracurricularactivitiesinyourschool?I'mlookingforwardtohearingfromyou.Bestregards,LiHua三、計(jì)算機(jī)學(xué)科（一）選擇題1.計(jì)算機(jī)的核心部件是（）A.顯示器B.內(nèi)存C.CPUD.硬盤答案：C2.以下哪種編程語言屬于面向?qū)ο缶幊陶Z言（）A.CB.C++C.FortranD.BASIC答案：B（二）簡答題1.簡述計(jì)算機(jī)網(wǎng)絡(luò)的主要功能。答：計(jì)算機(jī)網(wǎng)絡(luò)的主要功能有：（1）數(shù)據(jù)通信：實(shí)現(xiàn)計(jì)算機(jī)之間的數(shù)據(jù)傳輸，如電子郵件、文件傳輸?shù)?。?）資源共享：包括硬件資源（如打印機(jī)、硬盤等）、軟件資源（如各種應(yīng)用程序）和數(shù)據(jù)資源的共享。（3）分布式處理：將一項(xiàng)復(fù)雜的任務(wù)分解為多個(gè)子任務(wù)，分配給網(wǎng)絡(luò)中的不同計(jì)算機(jī)進(jìn)行處理，提高處理效率。（4）提高可靠性：當(dāng)網(wǎng)絡(luò)中的一臺計(jì)算機(jī)出現(xiàn)故障時(shí)，可由其他計(jì)算機(jī)代替其工作，保證系統(tǒng)的正常運(yùn)行。2.什么是操作系統(tǒng)？它的主要功能有哪些？答：操作系統(tǒng)是管理計(jì)算機(jī)硬件與軟件資源的計(jì)算機(jī)程序，同時(shí)也是計(jì)算機(jī)系統(tǒng)的內(nèi)核與基石。它的主要功能有：（1）處理器管理：負(fù)責(zé)分配和調(diào)度處理器
