学情分析
初中的英语教学内容难度增大，语法增多，单词量大，使得学生对英语产生了畏惧，学生的英语成绩差距很大，两级分化现象很突出。而我所执教的班级属于农村学校，农村学习由于地域和环境等因素限制，知识面较窄，开始时对学外语感到新鲜，但学习目的不明确。他们带着迷惘、新奇开始了英语学习。学生学习常会出现这样的 情况：感兴趣失去兴趣和信心厌烦和反感。开始阶段的学习热情高涨，当他们学会几个字母、几个单词和几个简单的句子时，课堂内外都可以听到牙牙学语的感人场 面。但曾几何时，这种景象很低快每况愈下，因为，这种热情仅仅凭借好奇心的驱动，他们全不知学英语的艰辛以及保持这股学习热情所需要的毅力。所以，一旦困 难接踵而至，日积月累，厌烦和反感便逐渐生成。
Unit 13 We’re trying to save the earth!
Section A( 3a----3b)
教学效果分析
本单元主要将焦点聚集在关于污染及环境保护的话题，同时将话题讨论更为具体的集中到了对于海洋生物鲨鱼的生存现状的讨论上。本单元时本册书的复习单元，在语法上主要复习被动语态，get used to结构及动词不定式作宾补的用法，以及宾语从句的用法。本节课的内容延续了上一节课对于环境污染的话题的讨论，同时将话题讨论更为具体的集中到了对于海洋生物鲨鱼的生存现状的讨论上。学生对于鲨鱼之类的海洋生物往往兴趣浓厚，该部分的内容设置能够很好的激发学生的学习兴趣，更好的学习本课的内容。
本节课是这一单元的第二课时，课堂氛围比较活跃，学生在回答问题的时候，都很积极，也很踊跃，课堂效果较好，在练习的同时，培养了学生的读说技能，合作能力。力求让学生在比较中鉴别，在运用中突破，理解中记忆，使复习课变得生动活泼有效。使每一个学生通过复习课的教学都能在自己原有的基础上知识得到拓展，能力得到提升，心灵得到舒展，情感得到升华。

课后反思
我所上的教材是人教版新目标英语九年级全一册Unit 13 We’re trying to save the earth!的Section A （3a----3b）部分。本单元以We’re trying to save the earth!为中心话题，围绕着对于环境污染的话题讨论，同时将话题讨论更为具体的集中到了对于海洋生物鲨鱼的生存现状的讨论上。学生对于鲨鱼之类的海洋生物往往兴趣浓厚，高部分的内容设置能够很好的激发学生的学习兴趣，更好的学习本课的内容。教学内容与学生的实际生活密切相关，易于引发学生运用简单的英语进行交际和交流。在学习活动中，比如在进行课文教授时，教师可用从网上下载的听说读写的英语材料，采用自制课件来进行教学，通过声，光，电的完美结合，用生动的形象，真是的画面，优美动人的语言和音乐，来丰富学生的想象力，刺激学生的兴趣和求知欲，增强学生的记忆效果，从实现教学目标，达到教学目的。
通过这节课，我感觉自己暴露了一些不足之处，首先，在运用操作多媒体上，幻灯片与幻灯片之间的衔接不够紧密，学生感到太突然，一时反应不过来要做什么。其次，以后再课堂上要都用激励性的课堂用语。再有就是，我感觉自己的评价性语言过于少，单调。最后，努力让自己的课堂更有效，

第二课时，本节课围绕着环境污染的话题展开，同时将话题讨论更为具体的集中到了对于海洋生物鲨鱼的生存现状的讨论上。通过了解鲨鱼的现状，增强保护濒危动物的意识。让学生感知保护濒危动物，学会保护鲨鱼。教师对学习材料和内容的处理，一般是由易到难，逐步深入，同时要考虑到对学生学习兴趣的一定刺激程度，使学生的思想始终处于积极状态，使他们的兴趣逐渐升级。增加教学环节中的趣味性，教学手段的多样化也有助于使学生的兴趣得以保持。易于引发学生运用简单的英语进行交际和交流，在学习活动中，教师通过抛出话题里鼓励学生积极发言，鼓励学生尽可能多的补充鲨鱼的相关信息和知识。然后教师播放与鲨鱼有关的视频资料，如介绍鲨鱼的生活习性，鲨鱼的生存现状，鲨鱼受到人类的围捕后的生存危机等，激发学生的兴趣，同时也为本节课的教学做好铺垫。在教学中，注重对学生综合能力的提升，在学习新词汇的同时巩固学过的语法知识点，提高学生的语言表达和运用能力，从整体上讲，我认为这节课是比较成功的一节课。

课标分析
义务教育阶段的英语课程力求面向全体学生，为学生发展综合语言运用能力打好基础，同时，促进学生整体人文素养的提高。教师应在教学中综合考虑语言技能、语言知识、情感态度、学习策略和文化意识五个方面的课程目标，根据学生的发展状况，整体规划各个阶段的教学任务，有效整合课程资源，优化课堂教学，培养学生的自主学习能力。
语言既是交流的工具，也是思维的工具。学习一门外语能够促进人的心智发展，有助于学生认识世界的多样性，在体验中外文化的异同中形成跨文化意识，增进国际理解，弘扬爱国主义精神，形成社会责任培和创新意识，提高人文素养。体现以学生为主体的思想，在教学目标、教学内容、教学过程、教学评价和教学资源的利用与开发等方面都应考虑全体学生的发展需求。英语课程应成为学生在教师的指导下构建知识发展技能、拓展视野、活跃思维、展现个性的过程。由于学生在年龄、性格、认知方式、生活环境等方面存在差异，他们具有不同的学习需求和学习特点。只有是大限度地满足个体需求，才有可能获得最大化的整体教学效益。
