高中英语新教材Unit11Scientificachievements教案
一、教学分析
1、教材内容分析
本单元围绕“Scientificachievements”这一中心话题,从科学家、科学假说、科学理论、科学探索等方面设计听、说、读、写等一系列教学活动。“Warmingup”部分设置了三个问题,要求学生就重要的科学成就进行讨论,从而帮助学生认识重要的科学成就,了解科学成就对社会发展、人类进步的重大贡献,同时激发学生热爱科学、投身于科学研究的热情,探索科学研究的方法。“Listening”部分设计了两道材料问题和一道开放性的情景话题。主要培养学生捕捉和筛选信息的能力,然后要求学生在一定语言输入后进行语言输出,旨在培养学生的想象能力和应用能力,通过自己的语言体会重大科学成就的意义。“Speaking”部分重点训练表达意图和愿望的日常交际用语,以五人小组的活动形式组织学生扮演科学家的角色,陈述各人的研究方向并阐明其重要性来申请科研经费。“Reading”部分为一篇介绍中关村的形成、发展及其重要意义的记叙文。通过对文章的理解,学习中关村人的创业精神。“Languagestudy”部分由词汇和语法两部分组成,该部分不仅教授了四种构词法知识,更鼓励学生通过四项练习,运用构词法知识提高阅读能力。“Integratingskills”部分设计了一个阅读和写作的练习,在学生了解四大科技成就及其重要性后,要求学生略加扩充写一篇最伟大的科学成就的文章。“Tips”部分提出了说服性写作必须论点明确、论据充分,为写作提供了写作方法。
2、教学重点、难点:
本单元的重点在于借助“高科技成就”这一话题,学习、复习涉及这一话题的有关语言知识和语言技能(见教学目标),激发学生热爱科学、奋发图强、献身于科学的热情。
本单元的难点在于培养学生充分利用已有的英语知识表达自己,谈论科学家、科学成就、理想抱负。
二、教学目标
1、语言知识目标
1)要求学生掌握必要的单词、词组和句型:solar,constitution,private,grasp…It’likelythat…,makeitpossibleforsbtodosth…,etc.
2)掌握一定量的表达“wishesandintentions”的交际功能用语。
3)同时要求学生掌握本单元出现的构词法及一些常见的前缀后缀及词根的意义。
2、语言技能目标
通过本单元的内容培养学生良好的“听、说、读、写”的技能,使学生能运用所学的知识解决相关情景中的一些类似问题,并能结合所给任务,综合运用新旧知识解决问题,完成任务,在此基础上鼓励学生大胆地根据各自的语言基础与能力,有个性地解决问题,就科学成就提出独特的见解。
3、情感目标
1)激发学生并提高学习英语的兴趣,乐于接受新鲜事物,勇于尝试:体现课堂教学“主体者”的身份,积极主动地参与教学各环节,成为学习的主人:具有个性,培养创造能力。
2)培养同学之间日常融洽相处的感情,乐于合作,善于合作的团体合作精神。
3)通过课文中出现的科学家及科学成就激励学生热爱科学、投身科学研究、探索科学研究的方法
三、教学策略
1)开放式教学策略。以有限的课堂为载体,带学生进入广阔的知识天地。
2)引趣激趣策略。创设多种情景(境)激发学生的兴趣,只有让学生真正有了参与的欲望,才能点燃他们的思维火花。
3)合作学习策略。合作学习强调通过师生、生生的多边互动进行人际交往、信息交流,能满足学生个体内部需要。
4)体验成功策略。使学生在特定的完成任务过程主动积极地获得和积累相应的学习经验,享受成功的喜悦,从而提高学习兴趣和成就动机。
四、学习策略
引导学生利用图书馆和网络资源进行一系列的自主学习、合作探究的学习策略。对于本单元鼓励学生课前收集科技成就、中关村和美国的硅谷的资料,上课时勤思考、主动参与课堂上的各种活动。
五、单元教学设计
依据《新课程标准》及对于学生教学目标的要求,课堂设计本着教学应“以人为本”的总的教学理念,课堂中充分利用网络资源、设计相应难度的任务,以增加教学的直观性和趣味性,提高教学效率。根据学生学习英语的特点和规律,学习阶段的侧重点,我把本单元划分六课时完成:听力、口语、阅读(2课时)、语言、写作、评价。

教学反思
本单元的教学设计从学生实际出发,以科技成就为主线设计了若干情景与活动,旨在让学生积极参与学习活动,开口说英语,并使学生在轻松愉快的氛围中掌握语言知识,锻炼阅读理解能力。在教学实践中笔者体会到,教学应注意以下几点::
1.学生在合作中学习更有助于提高学生学习的积极性,以及课堂参与的积极性。所以应当发挥小组功能,在合作中操练。小组活动是课堂活动的主要形式,如何落实小组中各个学生的角色是组织好小组活动的关键。这需要教师长期的训练。
2.设计活动时要充分考虑学生的情感态度,要设法让学生在快乐中学习。但教师不能片面地追求所谓的“快乐”,一味强调课堂气氛的活跃,而忽视学生对知识的掌握和对学生能力的培养。
3.信息技术的运用要为教学服务,不可喧宾夺主。在教学过程与信息技术的整合过程中,教师应注意信息技术只是一种辅助手段,不能由它控制全部流程。同时也应有效地利用这种手段,加快课堂节奏,增加课堂容量,提高课堂教学效率,使课堂气氛更加活跃,让学生在轻松愉快的环境中得到感情上的升华。
4.要处理好实践与反思的关系。反思是实践的一面镜子,能折射出实践中的成功和不足之处,以期在以后的教学中借鉴成功,改进不足。

教材分析
本单元是围绕Firstaid,Safetyinthehome,展开话题。对话课中描述两个学生在街上看到一个女孩从自行车上摔下来的经过,同时对话中使用了情态动词的用法,课文中附有图片和口语练习,帮助学生了解急救的重要性及有关的常识。
重点难点:
1.Whatshouldyoudoifapersonhasdrunkpoisonbymistake?假如有人误喝了毒药,你怎么办?
bymistake是固定词组,意为“错误地”,“无心地(做错了事)”。例如:
Sheputsaltinhercupofcoffeebymistake.她错将盐放入咖啡里了。
2.dowith,dealwith
二者都可以用来表示“处理”的意思
但是用于特殊疑问句的时候dowith与what连用;dealwith则与how连用。例如:
你会怎样处理一个从自行车上摔倒而严重受伤的?
另外,dowith还可表达别的意思。例如:
Whatdidyoudowithmyumbrella?(=Wheredidyouputmyumbrella?)
你把我的伞放到哪里去了?
Whatarewetodowiththisnaughtyboy?(=Howarewetodealwiththisnaughtyboy?)我们该怎样处置这个顽皮的男孩?

语法:情态动词(ModalVerbs)
1)must
A.表示必须要干的事。如:
Wemustobeytherules.我们必须遵守规则。
Youmustn’ttalklikethat.你可不能那样说话。
must也可以表达过去情况,主要用于间接引语中。
Shesaidthatwemustwaitalittlewhile.她说我们必须要等一会儿。
B.表示一种推测(只用于肯定句中,语气比may要肯定得多)。
musthave则表示对过去情况的推测。例如:
ThismustbeTom’sroom.这准是Tom的房间。
Jackmusthavegonethere,hasn’the?/didn’the?杰克准是去过那儿了,对不对?
C.比较:haveto也表示“必须”,但haveto更强调客观需要,must着重说明主观看法。如:
Wehadtobethereat10o’clock.我们得在10点到那儿。(客观需要)
Wemustbebackbefore10o’clock.我们必须10点前回来。(主观认为)
有时也可互换:
Wemust/havetoleavenow.我们得走了。
must和haveto的否定式即mustn’t和don’thaveto意思完全不同。Mustn’t表示“不作某事”,有禁止的含义;don’thaveto表示“不必要(作某事)”,含有“客观上无此必要”的意思。例如:
Youmustn’tmovesomeoneifthepersonisbadlyhurt.如果这人受了重伤,你一定不要动他.
Thepersonisn’thurtatall.Youdon’thavetogivehimfirstaid.这个人根本就没有受伤,你不必给他进行急救。
