第一篇：说明文写作口诀和说明文写作口诀和范文口诀：说明文写作注重“序”，依据信息来动笔，时间、空间和逻辑，“三种顺序”选其一。要把说明文写得条理分明，就要掌握一定的说明顺序。常用的说明顺序有：空间顺序、时间顺序、逻辑顺序。空间顺序是指从整体到局部，从上到下，从内到外的顺序；时间顺序是指时间上从先到后的顺序；逻辑顺序是指先因果或先果后因或先主后次的顺序。参照模式：1、顺序说明法：TheseareseveralreasonswhyIdecidedtostudyinthisschool.Firstofall,thestudentsinthisschoolarefriendly.Secondly,thereisabiglibraryand3bigcomputerrooms.Thirdly,therearemanyfinestteachers.Finally,thisschoolisnotfarfrommyhome.Itwon’ttakemelongtimetogotoschool.这段文章介绍了一个学生在这个学校学习的理由。全段层次分明，连接词语（firstly,secondly,thirdly,finally）运用得当。2、举例说明法Computersareveryimportantinourlives.Forexample,theycandomanykindsofwork.Youcangetlotsofinformationonthem.Youcanalsowatchinterestingmoviesandvideos.Bytheway,downloadingmusicisagoodchoice.Weevenusethemtoplaycomputergamesathome.Todayalotofpeoplebuycomputers.Computersarebecomingmoreandmorepopular.本段文章首先说明了电脑的重要性，然后用forexample来举例说明电脑的不同用途。3、因果关系法Ofallthepets,Ilikedogsbest.Ipreferdogsbecausedogscandolotsofthingsforpeople.Peoplekeepadognotonlyforpleasurebutalsoforsafety.Adogcanbeaguard.Inthecountry,farmersliketokeepdogsforpleasure,too.Besides,someofthedogscanhelpfarmerstolookafterotheranimals,suchassheepandpigs.Dogscanbeagreathelptoarmysoldiersandpolicemen.Dogsoftendoimportantworkforthem.Sodogsarereallyourgoodfriends,andwemusttakegoodcareofthem.第一句是本段的主题句，末句是总结句。在主题句后，作者用连词because引出了句子来阐述自己喜欢宠物狗的理由。实践演练：一、为配合我市举行的“6.5世界环境日”万人骑自行车城区环游活动，请你写一篇一LowerCarbon(低碳),HappierLife为题的英语短文。（以上背景内容无须表达）短文要点如下：1、在6月5日自己骑自行车上学，父母骑车上班。2、在家使用节能灯，减少洗澡淋浴时间。3、将用过的课本留给下届学生。4、请你就此话题补充1~2个个人做法。要求：1、不要逐次翻译；2、在文中不要提及真实的校名和姓名；3、词数80左右，短文标题和首尾句已给出，不计入总词数。参考词汇：节能灯energy-savinglamp用过的used下届lowergradesLowerCarbon,HappierLifeIt’sourdutytosavetheenvironment.IwillgotoschoolbybikeinsteadoftakingthebusonJune5.AndIwillalsoaskmyparentstoridetoworkthatday.Athome,wewilluseenergy-savinglampsandspendlesstimewhenwearetakingashower.Don’tthrowawaytheusedtextbooksandleavethemtothestudentsoflowergrades.Atthesametime,Iwilltellmyparentstotakebagswhentheyareshopping.Iwillturnoffthelightsbeforeleaving.
