16、语的兴趣。 人教版新课标必修二第四单元 一、说教材1、教材的地位及作用本单元以保护动物为话题，旨在通过本单元的学习使学生了解很多动物已经灭绝或濒临灭绝，从而认识到保护动物的重要性和必要性。并且通过探讨保护动物的措施和建议，引导学生发表自己的见解和看法，唤起学生保护动植物、维护生态平衡、保护我们家园的责任感。本课Reading讲述的是一篇童话故事Daisy乘坐飞毯跨越时空和藏羚羊、大象、猴子对话的神奇经历。通过故事，帮助学生逐渐认识到保护野生动物的重要性，并了解该如何保护野生动物，号召人们热爱动物，保护动物，从我做起。在本单元中，Reading前面的Warming up及pre-reading是

17、该部分的铺垫，后面的listening, speaking等几部分都是Reading的延伸和扩展。所以说Reading部分承载了本单元的主要信息，又集中了大量的有用词汇和语言结构，起到承上启下的作用。（根据教学大纲及新课程的要求，确立了本课的教学目标及教学重难点。）2、教学目标（1）认知目标a、重点词汇和短语：wild, wildlife, protection, decrease, loss, reserve, hunt, zone, peace, respond, distant, mercy, importance, powerful, affect, attention, apprec

18、iate, secure, die out, in peace, in danger of, in relief, burst into laughter, protectfrom, pay attention tob、重点句式：Daisy had always longed to help endangered species of wildlife. (L.1) Im protecting myself from mosquitoes. (L.28) No rainforest, no animals, no drugs. (L. 31) But what an experience! (

19、L.35)（2）技能目标 通过阅读，训练学生获取语篇信息、分析、处理、利用信息的能力； 掌握猜测、略读、扫读的阅读技巧； 掌握如何保护野生动物的知识； 培养学生口头表达能力。（3）情感目标 让学生学会如何保护野生动物，进一步意识到野生动物的生存环境日益恶化以及保护野生动物的行动刻不容缓。3、教学重、难点 让学生了解野生动物保护的知识； 提高学生的阅读能力。二、说学情新课程强调“以人为本，以学生为主体”的教学思想。那么作为一名合格的教师，了解学生是我们最基本的职责。作为高中阶段的学生对周围的事物较为敏感，有自己的观点和看法，他们不满足于教科书上的知识，想获得更多的信息。在英语学习上，他们不只是想

20、把英语作为一门死记硬背的课程来学，更希望能学到知识性和趣味性兼有的内容，从英语学习中获得更多的知识和能力。但是他们的词汇量是有限的，并且缺乏阅读技巧。且从学生学习语言的规律来看，高一年级是学生的阅读能力提高的重要阶段。而从以往普通班的教学来看，学生在阅读一篇300字以上的文章时，阅读速度较慢，有许多不好的习惯，如逐字阅读，朗读式阅读等等。其次，他们的理解正确率往往低于70%。三、说教法 根据学生学习的实际情况确定教学活动的难度，即因材施教，是新课程理念下对英语教学最基本的要求。那么依据学生实际情况，结合本单元的主题及本课的内容，为突出重难点，以达到预定的教学目标，我采用了“导、读、练、说”的整

21、体课文阅读教学法，即在老师的引导下，学生的自主阅读和训练。从而激发学生兴趣，主动学习，学有所获。1、任务型教学法我给学生设计了读前任务：为什么现在越来越多的野生动物濒临灭绝的边缘？而作为学生，面对这种情况，我们应该采取什么措施？从而让学生明白保护野生动物的重要性。读后任务：角色扮演。根据阅读中所出现的角色Daisy，Carpet，Antelope/Elephant/Money，分组扮演，进行对话。课后任务：让学生通过多种渠道获取更多关于濒危动物及如何保护野生动物的信息。通过以上任务的实施，让学生进一步的理解课文主题，使学生“以具体的教学任务为载体，以完成任务为目标，把知识与技能融为一体”。2、

22、图片导入法 在教学过程中，教师的基本任务是“导”，即起组织和引导的作用。本课采用图片导入。利用一些关于濒危动物的图片，引出本课的主题，并用提问、启发、分析、归纳相结合的教学方法。四、说学法现代的教育理念认为“获得知识的过程比获得知识更重要”。因此，在本课中，我采取以下方法指导学生学习。首先是自主学习法。引导学生课前预习单词，并思考有关问题，从而达到学生自主参与学习的目的。其次是猜测法。通过文章题目，预测文章主题。最后是合作法。讨论及角色扮演活动以小组活动的形式进行，帮助学生提高他们的合作能力及合作精神，从而激发学生的学习兴趣。这种自主参与学习、交流合作，倡导体验、实践和自主探究的学习方式，能够

23、使学生自主地寻找信息，获取信息、使用信息，在自主与合作的学习方式中获取知识，形成正确的学习方法，实现阅读能力与表达能力的提高。五、说教学过程现代外语教学必须要遵循“以学生为主体，教师为主导，培养学生创新能力”的理念，即让学生在教学活动中发挥其主体地位，在教师的引导下去发现、分析和解决问题。根据此理念，在整个教学过程中，始终坚持以学生实际结合课文主题的原则，设计了由浅到深，循序渐进的活动，使学生积极主动参与，进行创造性学习，实现知识与技能的融合，解决实际问题。本课的教学过程主要分为四个步骤Warming-up；Pre-reading；While-reading；Post-reading。共计教学

27、绝的原因，从而有效地引导学生进入本课主题如何保护野生动物。不仅能够激发学习兴趣，还渗透德育教育，为下面的阅读作好铺垫。而讨论也有利于激发学生的分散性思维。增加学生的课外知识，而不仅限于课本知识。Step II Pre-reading(2mins)Prediction:Look at the title to predict what the passage is about.预测主题有助于学生把握文章的总体思想，培养学生的推理能力。Step III While-reading(22mins)Task 1 Skimming for the general idea What is this pa
