{

inta=10,b=3;

intc=a%b;

intd=a/b;

cout<<c+d<<endl;

return0;

}请写出程序运行结果。程序阅读2PlainText

#include<iostream>

for(inti=1;i<=5;i++)

{

if(i%2==0)sum+=i;

}

cout<<sum<<endl;

return0;

}请写出程序运行结果。三、完善程序题（共1题，20分）题目功能：输入一个正整数n，计算1~n所有整数的累加和，补全空缺代码。PlainText

#include<iostream>

usingnamespacestd;

intmain()

{

intn,sum=0;

cin>>n;

for(inti=1;____(1)____;i++)

{

____(2)____;

}

cout<<sum<<endl;

return0;

}四、编程题（共1题，30分）【题目名称】偶数求和【题目描述】输入两个正整数L、R（1≤L≤R≤1000），统计并输出区间[L,R]内所有偶数的和。【输入格式】一行两个整数L、R【输出格式】一行一个整数，表示区间内偶数总和【样例输入】210【样例输出】30NOIP2026模拟试题详细答案及解析一、单项选择题答案1.D解析：程序三大基础逻辑结构为顺序、分支、循环，递归是算法思想，不属于基础结构。2.B解析：变量名不能以数字开头、不能包含特殊符号、不能使用关键字，num_1符合规范。3.C解析：1×2³+1×2²+0×2¹+1×2⁰=8+4+0+1=13。4.B解析：栈是典型的先进后出（LIFO）数据结构，队列是先进先出。5.B解析：冒泡、选择、插入排序时间复杂度均为O(n²)，快速排序平均时间复杂度为O(nlogn)。6.C解析：标准C++中int整型固定占用4个字节。7.B解析：浏览器后退记录由栈实现，其余场景均适合队列结构。8.A解析：26=16+8+2，对应二进制11010。9.C解析：switch为多分支判断语句，不属于循环语句。10.A解析：二叉树节点固定时，完全二叉树层数最少，为log₂n上取整。二、阅读程序题答案1.运行结果：4解析：a%b为取余运算，10%3=1；a/b为整数除法，10/3=3；1+3=4。2.运行结果：6解析：循环遍历1-5，仅累加偶数2、4，总和为2+4=6。三、完善程序题答案(1)i<=n(2)sum=sum+i（或sum+=i）解析：循环条件控制遍历1到n的所有整数，循环体内实现数值累加，完成求和功能。四、编程题完整代码及解析PlainText

#include<iostream>

usingnamespacestd;

intmain()

{

intL,R,sum=0;

cin>>L>>R;

for(inti=L;i<=R;i++)

{

//判断是否为偶数

if(i%2==0)

{

sum+=i;

}

}

cout<<sum<<endl;

return0;

}解析：遍历区间内所有数字，通过取余运算筛选偶数并累加，最终输出总和。样例中2、4、6、8、10累加和为30，与样例输出一致。第二部分职教英语综合试题（中职统考难度）一、单项选择（共15题，每题1分，共15分）从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。1.Mymotheroften______breakfastformeeverymorning.A.cookB.cooksC.cookingD.cooked2.There______abookandtwopensonthedesk.A.isB.areC.wasD.were3.Iusuallygotoschool______foot.A.inB.onC.byD.at4.—______isyourbirthday?—It’sonJune10th.A.WhatB.WhereC.WhenD.How5.Thisis______usefuldictionary.A.aB.anC.theD./6.He______toBeijingtomorrowmorning.A.goB.goesC.willgoD.went7.Mysisterisgood______dancing.A.atB.inC.forD.with8.______heavilyitisraining!A.WhatB.WhataC.HowD.Howa9.Ihavelivedhere______fiveyears.A.sinceB.forC.inD.on10.You______bequietinthelibrary.A.canB.mayC.mustD.could11.Shelikesmusic,______shedoesn’tlikesports.A.andB.butC.orD.so12.Themovie______fortenminuteswhenwegotthere.A.hasbeenonB.hadbeenonC.wasonD.ison13.Couldyoutellme______thenearestsupermarketis?A.whatB.howC.whereD.when14.Iprefertea______coffee.A.toB.thanC.withD.for15.—Thankyouverymuchforyourhelp!—______A.AllrightB.That’srightC.You’rewelcomeD.Nevermind二、完形填空（共10题，每题1.5分，共15分）阅读下面短文，从各题所给的A、B、C、D四个选项中，选出最佳选项。Iamavocationalschoolstudent.MynameisLiHua.Istudyinabeautifulschool.Therearemanytreesandflowersinourschool.Theteachersarekindandpatient,___16___theclassmatesarefriendly.Imajorincomputertechnology.Ithinkitisauseful___17___.Ilearnmanyprofessional___18___everyday,suchascomputeroperationandbasicprogramming.Istudyhard___19___Iwanttofindagoodjobinthefuture.Afterschool,Ioftentakepartinschoolactivities.Ilikeplayingbasketball___20___myclassmates.SometimesIreadbooksintheschoollibrary.Readingcan___21___mealotofknowledge.Myschoollifeisbusy___22___colorful.Ifeelveryhappyandfulfilledeveryday.Iwillcherishmyschooltimeand___23___improvingmyprofessionalskills.Ibelievemyhardworkwill___24___oneday.IhopeIcanbecomeausefulpersonto___25___society.16.A.soB.andC.butD.or17.A.jobB.subjectC.schoolD.hobby18.A.skillsB.gamesC.storiesD.songs19.A.becauseB.thoughC.ifD.so20.A.forB.withC.toD.at21.A.takeB.carryC.bringD.get22.A.orB.butC.andD.so23.A.keepB.stopC.finishD.enjoy24.A.takeoffB.payoffC.turnoffD.putoff25.A.theB.aC.anD./三、阅读理解（共10题，每题2分，共20分）Passage1MynameisTom.Iama19-year-oldvocationalstudent.Istudymechanicalmanufacturinginavocationalschool.Atschool,Ihavebothculturalcoursesandprofessionalcourses.Ilikeprofessionalcoursesbest,becausetheyarepractical.Icanlearnhowtooperatemachinesandmakesimpleparts.Myteacheralwaystellsusthatpracticemakesperfect.Everyweek,wehavethreedaysofpracticaltrainingintheschoolworkshop.Aftergraduation,Iplantoworkinamanufacturingfactory.Iwanttobeaskilledtechnician.Iknowvocationalskillsareveryimportantforourfuturecareer.Iwillkeeppracticingandimprovingmyabilitytoadapttosocialworkneeds.26.WhatisTom’smajor?A.ComputertechnologyB.MechanicalmanufacturingC.NursingD.Cooking27.WhydoesTomlikeprofessionalcourses?A.TheyareeasyB.TheyarepracticalC.TheteacherisfunnyD.Theyhavenohomework28.HowmanydaysdoesTomhavepracticaltrainingeveryweek?A.TwodaysB.ThreedaysC.FourdaysD.Fivedays29.WhatdoesTomwanttobeinthefuture?A.AteacherB.AmanagerC.AtechnicianD.Aworker30.WhichofthefollowingisTRUE?A.Tomis18yearsoldB.TomonlyhasprofessionalcoursesC.TomvaluesvocationalskillsD.TomhatespracticaltrainingPassage2Nowadays,moreandmorevocationalstudentspayattentiontoEnglishlearning.Englishisnotonlyaschoolsubject,butalsoausefultoolinfuturework.ManyenterprisesrequireemployeestohavebasicEnglishability.Forexample,workersinforeigntradecompaniesneedtoreadEnglishdocumentsandcommunicatewithforeigncustomers.TechnicalstaffneedtounderstandEnglishproductmanualsandoperationinstructions.Forvocationalstudents,learningEnglishwellcanbringmorejobopportunities.Itcanhelpusgetbetterjobsandbroadenourhorizons.WeshouldinsistonlearningEnglisheveryday,listenmore,speakmoreandpracticemore.31.Whatdoesthepassagemainlytalkabout?A.HowtolearnEnglishquicklyB.TheimportanceofEnglishforvocationalstudentsC.EnglishlearningmethodsD.Enterprisejobrequirements32.WhydotechnicalstaffneedEnglish?A.TotalkwithfriendsB.TopassexamsC.TounderstandEnglishproductmanualsD.Totravelabroad33.WhichbenefitcanEnglishlearningbringtostudents?A.MorejobopportunitiesB.MorefreetimeC.HigherexamscoresonlyD.Lessstudypressure34.Theunderlinedphrase“broadenourhorizons”means______.A.提升成绩B.开阔眼界C.锻炼身体D.积累财富35.Whatisthewriter’sadvice?A.LearnEnglishbywatchingTVB.InsistondailyEnglishpracticeC.OnlylearnoralEnglishD.LearnEnglishaftergraduation四、句型转换（共5题，每题2分，共10分）按要求改写下列句子，每空一词。36.Igotoschoolbybus.（对划线部分提问）____________yougotoschool?37.Hecanfinishtheworkontime.（改为否定句）He____________theworkontime.38.Sheisaverykindgirl.（改为感叹句）____________kindgirlsheis!39.Ihavelivedherefor3years.（对划线部分提问）____________haveyoulivedhere?40.Thebookisveryinteresting.（改为同义句）Thebook______great______.五、书面表达（共1题，40分）假如你是李华，你的外国笔友Peter想了解你的中职校园生活，请你根据以下要点写一封英文邮件：1.介绍所学专业（如计算机、机电、护理等）；2.日常学习内容（文化课+专业实操课）；3.课余生活与个人收获；4.未来的学习和职业规划。要求：词数80-100，语句通顺，语法正确，要点齐全。职教英语试题详细答案及解析一、单项选择答案1.B解析：everymorning为一般现在时标志，主语mymother为第三人称单数，谓语动词用三单形式cooks。2.A解析：therebe句型遵循就近原则，紧邻be动词的abook为单数，用is。3.B解析：固定搭配onfoot步行。4.C解析：答语
