我的教学对象为高二的学生。经过高一整年的英语学习，他们已经储备了一定的高中英语词汇和基础知识，认知水平和分析能力比高一年级阶段有了很大程度的提高。学生们能够就老师给出的话题材料展开讨论，发表他们自己的观点看法。他们渐渐具备了用英语获取信息和处理信息的能力。同时他们分析问题和解决问题的能力也得到了完善和提高。我相信，我们的学生经过阅读课一次次锤炼，他们的阅读技能和阅读速度都会有提升。

Unit4Globalwarming效果分析就学生而言，兴趣是最好的老师。真正的课堂是学生在快乐中学习，在幸福中成长，在学习中感受快乐，在成长中收获着幸福。通过看视频和一篇报告，然后回答问题的方式导入，可以使学生自然而然地进入学习新知识的情境，并能激发学生的兴趣和强烈的求知欲，在最短的时间内，使学生进入最佳的学习状态。本节课我分层次教学，小组合作，小组讨论活动较多，给学生创造读说写的机会，让学生感到英语就在身边，调动了学生的参与积极性，促进了英语高效课堂的形成。在授课过程中，我真心地走进学生，真情地亲近学生，给学生一种亲和力，形成民主教学气氛，使学生能在一个宽松的良好氛围里学习。快读和细读环节都对学生进行学法指导，让学生会主动学习。通过让学生比较文中出现的两个曲线图以及全球升温带来的不同影响，有效地培养了学生的动脑动手能力。老师多方面的鼓励令学生收获成功的喜悦，让学生在欣赏中体验到成功的快乐，体验到学习英语的兴趣，从而以更加饱满地精神状态积极地投入到学习中。总之，我认为这是一堂成功的课！我还要继续努力，争取更大的进步！

Unit4Globalwarming教材分析本单元的中心话题是人类当今面对的环境问题，主要讨论了“全球变暖”和“节约能源”等方面的问题。由于人类过多使用不可再生能源，大气中二氧化碳的含量逐年增加，导致全球气温上升。通过本单元的学习，让学生了解能源分为“不可再生能源”和“可再生能源”，帮助学生树立“节约能源、保护环境”的主人翁意识。Theearthisbecomingwarmer–butdoesitmatter?是主阅读篇章，也是本单元的亮点。它是一篇杂志文章，主要讲述了地球温度上升的现象和原因。20世纪中地球温度上升了华氏1度，这种现象是自然发生的还是人为的？这个问题引起了激烈争论。对于地球升温，科学家持有不同的看法。有些科学家认为这个问题很严重,也有科学家认为地球升温有利于改善人类生活。文章最后以开放性的问题结尾要求读者思考：对于全球变暖，人类要不要采取措施？问题形式能够引起学生的兴趣，同时留给学生更多的思考空间。能够激发学生的想象力，同时锻炼了学生动脑动口动手能力。Unit4Globalwarming评测练习一．Usethecorrectwordtofillineachblank.Pricesarerising(steady).Thegovernmentisnowreducingair(pollute).Thepresidentmadea(state)ofhisaims.Doyoubelieveinthe(exist)ofghosts?Foodproductionhasfallenbehindthepopulation(grow).Howdidyoudealwiththe(disagree)betweencolleagues.Hehasdrunkonecupofcoffeeto(flesh)himself.Hisdreamwastobeawell-known(educate).Hemadeapositive(contribute)tothesuccessoftheproject.Lastweekwewenttothe(present)ofanewplay.二．Completethefollowingsentenceswiththephrasesbelowinthecorrecteabout;goup;resultin;beopposedto;keepon;onbehalfof;comeabout;goup;resultin;beopposedto;keepon;onbehalfof;putupwith;solongas;subscribeto;turnupIcanhardlyheartheradio.Wouldyouplease?Thecarcrashthreepeoplebeingkilledandoninjured.Whichjournalsdoesthelibrary?Thepriceofoilhasbyover50percentinlessthanayear.Atfirsttheythescheme,butwemanagedtoarguethemaround.alltheguestshere,Iwishtothankyouforgivingusthiswarmreception.Wewanttoknowhowitthathumansspeaksomanydifferentlanguages.“Iwillnotyourbadbehavioranylonger,”saidthegirlangrily.Youcancertainlydoitwellifyoupracticinghard.Idon’tcareabouttheprice,thecarisingoodcondition.Unit4Globalwarming
