题的能力。最后，引导学生树立“liveinharmonywithnature”的意识。StepV.Extendedviews---VoicefromgreatmenWeshouldliveinharmonywithnature-----1.Wewon’thaveasocietyifwedestroytheenvironment.-----MargaretMead2.Onlytoobeynatureinordertoovercomenature.-----CharlesDarwin3.Youwillneverenjoytheworldaright,tilltheseaitselfflowedinyourvein,tillyouareclothedwithheavens,andcrownedwithstars.-----ThomasTraherne4.Natureiskindofalovingmother,butalsoabutcherincoldblood.-----VictorHugo5.Whenmanishappy,heisinharmonywithhimselfandhisenvironment.-----OscarWilde说明：该部分让学生欣赏体会并记忆几个名人名言，让学生体会和自然和谐共处的深层含义，让学生树立良好的自然观。这部分的设计是对课文南极洲这一主题的一个很好升华。StepVI.SummaryWhatwehavegotinclasssomewordstodescribeAntarcticasomeinformationrelatedtoAntarcticasomereal-lifesentencestheawarenessof“liveinharmonywithnature”说明：让学生背诵、整理课堂上积累的表达、句子。StepVII.HomeworkBasedonwhatyouhavelearnedinclass,trytoenrichandbetteryouropinionsonyourlittlebrother’slongingtotravelacrossAntarcticaandwriteacompositionaboutit.(100-120words)说明：课后作业的目的是对阅读内容的巩固和深化。该作业旨在让学生在阅读文章并进行讨论交流后，进一步丰富又改进语言、内容，形成一份书面作文。学情分析学习语言的关键在于语言知识的积累，高二学生已经储备了一定的英语知识，学生的阅读能力、理解能力、分析能力、判断能力、应变能力等均较之以前有所提高。对于南极及南极环境，大部分学生有一定的了解，他们思维比较活跃，敢于提出不同的见解，能较好地展开话题讨论，各抒己见。班上学生的英语基础有一定的差异性，因此，在设置阅读任务时要有一定的层次性，逐层递进，让不同基础的学生都能有所提高；预测学生在阅读过程中可能遇到的困难在于在有限时间内能恰当的理解、归纳、整理。因此，在必要的时间里给他们讨论的时间并给出有针对性和建设性的提示。效果分析通过对学生课上完成阅读任务的情况分析发现，学生基本可以理解文本信息，并对其进行分析、概括。然而，在语言运用和批判性思维方面还有待提高，因此在以后的教学中，教师应注意创设更多情境加强学生语言使用的准确性以及批判性思维的训练。教材分析本课学习的内容是外研版新课标B8M1DeepSouth中的Antarctica:theLastContinent阅读课。本模块介绍南极洲的一些情况以及探险家的探险活动，使学生初步了解南极洲的神秘，发挥对南极的想象，激发学生热爱南极、热爱科学探索的精神，并提升学生保护南极的意识。由于选修教材侧重于知识的融合、综合和复习总结，教材难度明显加大，词汇量也相应增大，文章篇幅加长。在实际教学的过程中，我对阅读材料进行了有效的整合，将文章分为两部分：一部分是南极的基本情况；另一部分是人类在南极的活动。在设计阅读任务方面：一方面，在阅读任务的设计中，坚持readthelines,readbetweenthelines,andreadbeyondthelines，难度层层递进，旨在不断加深学生对文本的理解与运用；另一方面，引导学生拓展延伸思维，加深对文章的理解并应用于实际，培养学生criticalthinking能力。评测练习一、单词拼写(单句首字母填空)21.Thesecreaturesliveinthed
