英语短文写作方法范例1．原因篇分析原因是英语议论文写作的一个常见题型。例如:Whydotoday'syoungpeoplehavedifficultyinreadingandwriting?Whyistheworldgettingsmallerandsmaller?WhyhasthedivorcerateinChinaincreasedinrecentyears?作文要求考生对这类社会现象或社会问题进行解释。按照十句作文模式，这种类型的作文的基本写法如下:PIS(l)Problem(general)S(2)Problem(specific)PIIS(3)ThesisS(4)Cause1S(5)Detail1S(6)Detail2S(7)Cause2S(8)DetaillS(9)Detail2...PIIIS(10)conclusionSample1WhyCollegeStudentsTakeaPart-timeJobOutline:1.最近几年越来月多的大学生加入打工队伍2.为什么大学生要打工3.大学生打工的意义用数据和事实(1)Accordingtoarecentsurvey,引出将要讨论about25percentofChinesecollege的现实studentsnowholdapart-timeortemporaryjob,comparedwithnearlynone10yearsago,andthisfigureincreasesto72percentduringsummer形象化描写vacation.(2)Collegestudentsareseenwaitingontables,clerkinginstores,advertisinginstreets,teachinginfamiliesanddoingwhateverworktheycanfind.承上启下,引出解(3)Whydotheywantodd释/同位语jobs--jobsusuallyrequiringlittleskill原因一/短句变化andknowledge?(4)Theprimaryreason,Ithink,ismoney.(5)Feelingthepressureofsoaringinflationasbooks，moviesandbusfareshaveallgoneupinprice,thereisscarcelyayoungboyorgirlwhodoesnotwantto措词变化earnalittlemoneytohelpcovertheincreasinglyhighercollegecosts,andatbestsaveenoughtogotravelingorbuythingstheyhavelongdesired.(6)Inthiswaytheyhopetobeeconomicallyindependentandavoidtheindignityofhavingtoaskformoneyagainandagain.原因二(7)Besidestheywanttogainsomeexperienceinthewaysofsociety.(8)Studentsgrowingupfromnurseryschooltocollegeonlyknowaboutbooksandhave措词变化troubledealingwithrealities.(9)Workingonapart-timebasiscanprovidethemwitharareopportunitytoknowtheoutsideworldandpreparethemforafuturecareer.总结全文，(10)Thesignificanceforcollege指明意义studentsofdoingapart-timejobmeansmorethanmoneyandexperience:Itwillbroadentheirout1ookandexertaprofoundinfluenceontheirpersonalityandlife.[评析]这篇作文主要是解释大学生打工这一社会现象。作者谈了两个方面的原因。一是money.由于近几年的通货膨胀、物价飞涨和大学生本身经济独立意识的增强，他们需要有钱。二是experience。这是因为书本知识和现实世界之间的距离以及大学生今后工作和生活的需要。文章最后一段虽只有一句，但作者不仅总结了全文的两个原因，而且还进一步指出了大学生打工对于他们人生观形成所具有的深远意义。好的结尾能使读者加深认识，起到画龙点睛
