1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。

1 交通工具的比较此活动为小组活动。学生通过讨论找出到达某一城市可乘坐的各种交通工具,并选择最佳出行方式。Teacher:We’re going to Shanghai. How many ways can we use to get there? Yes, there are four ways: by bus, by plane, by train, by ship. Please discuss how you are going to get there.操作建议:(1)学生以小组为单位展开活动,谈论本组所选择的交通工具。(2)各组选代表向全班汇报,阐述本组所选择的交通工具的利和弊。完成任务所需要的语言结构:We can go there by ship. It’s more comfortable and cheaper than any other transportation.We can go there by bus. It’s cheaper but it takes longer time.2 哪个城市更合适?此活动具有挑战性。假设中国要举行2014年世界杯足球赛,分别从历史,人文,天气等方面对各城市(北京,大连,上海,昆明)进行比较,选择最佳举办城市。T: Imagine China is holding the 2014 FIFA World Cup. Which city do you think is the best for the World Cup, Beijing, Dalian, Shanghai or Kunming? Let’s work in groups. If you choose Beijing, please join the Team Red. If you chose Dalian, please join the Team White. If you choose Shanghai, please join the Team Blue. If you choose Kunming, please join the Team Green. Please show us its advantages. Then let’s see which team will win.
教学重点和难点:运用所掌握的语言描述,比较不同地点的特点。在练习中学习掌握英语比较级和最高级的用法。课前准备分配小组,每组五至六人。通过上网或翻阅报刊杂志等方法,确定旅游线路,做出基本的旅游计划。教学设计:本节课流程图 学法指导:1.由于这是一堂新课,在教学中应注意面向全体,发挥学生的主体性,引导学生积极参与,激发学生的求知欲和学习积极性,指导学生积极思维,主动获取知识,养成良好的学习方法。逐步学会独立解决问题。总之要尽可能调动学生的非智力因素促进智力因素的发展。教法选择:1.电化教学法2.课堂讨论法3.任务型教学法采用这些方法的目的是为了充分调动学生的学习积极性,使学生变被动学习为主动学习。通过电脑形象的演示,加强印象,提高兴趣,突破难点,提高教学效率,进而增大教学的容量和信息量。充分体现教师为主导,学生为主体的教学原则。

“Go for it!” is based on “Task-Based Language Teaching”. It adheres to “The authenticity principle”, “The form-function principle”, “The task dependency principle” and “The principle of learning by doing”. These principles all accord with the demands of curriculum focus.In and of Grade Seven (II), “Go for it!”, students have learned “The Simple Past Tense”. And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B. Thus, they can describe the events in the past freely and foster their own ability of reflecting and practicing. II. Teaching ObjectivesTeaching objective is the beginning and aim of teaching activities. According to the overall goal of the English elementary course--- improve students' synthetic ability of language application, which should be based on the development of students’ “Language knowledge”, “Language skills”, “Character building”, “Learning strategies” and “Cross-cultural awareness”. The teaching objectives are described as follows(I). Knowledge objectivesi. Master the simple past tense of regular and irregular verbsii. Recite the new words and expressions about the last school trip in the aquarium, including their pronunciation and intonation

内容提示本单元主要内容是学会利用verb十by/with gerund表示方式方法来讨论学习英语的策略,认识自己在学习方面的长处和不足。初步了解现在完成时的结构和用法。现在完成时由助动词have/has+动词的过去分词构成,主要表示过去发生的某一动作对现在仍有影响或造成的后果,常与already,yet,just,ever,never等副词连用。教学目标一、学习目标(Language Goal) 1. Talk about how to study . 学会讨论各种学习方法和策略。2. Find out your suitable learning methods. 找出适合自己的学习方法。 二、语言结构(Language Structures) 1. Verb + by with gerund by+动名词短语 表示“通过…途径,方法” 2. How questions have引导的特殊疑问句 三、目标语言(Target Language) 1. How do you study for tests ? 你是怎样准备考试的?Well , I study by working with my classmates. 哦,我和同学们一起学习。2. Have you ever studied with a group ? 你曾经参加过学习小组吗?Yes , I have . I’ve learned a lot that way . 是的,参加过。通过这种方式我学了许多。
(1)吾尝(曾经)终日而思矣,不如须臾(片刻)之所学也;吾尝肢(踮起脚跟)而望矣,不如登高之博见(看得广)也。(学、思对比,强调了学习的作用;跛望与登高对比,登高的收获大。两例证明利用学习、利用外物的作用。)(2)登高而招(招手),臂非加长也,而见者(看的人)远(远也看得见);顺风而呼(呼喊),声非加疾(快)也,而闻者(听的人)彰(听得更清楚)。(两例证明利用自然条件的作用。)(3)假(借助)舆马者(的人),非利足(快脚)也,而致(达到)千里;假舟楫者,非能水(善游)也,而绝(横渡)江河。(两例证明利用工具的作用。)(4)君子生(性)非异也,善假(利用)于(对)物(外物)也。连用比喻,得出结论:那些有才德的君子,生来本性与普通人没有什么两样(生非异也),只是由于他善于利用学得的知识和本领,善于利用处界条件弥补自身的不足,不断提高自己,所以才成为君子的。
一、 说教材《阿西莫夫短文两篇》是全日制普通高级中学教课书人教版八年级上册第2单元的第2篇课文。本册书说明文阅读共两个单元,可以说重在培养学生对说明文的阅读、理解、分析的能力和注重观察、讲究实证的科学态度以及求真创新的科学精神。本单元的学习重点是:整体感知,注意说明的顺序和方法;提高默读的速度;能按照要求筛选信息。《阿西莫夫短文两篇》是一篇典型的科普说明文,两篇短文《恐龙无处不在》和《被压扁的沙子》都有关于恐龙,但是说明的对象又有所不同,又结合班级情况和单元重点。在重难点上不必面面俱到,只是重在培养他们阅读说明文的能量从而积累知识。二、说教法说明文是相当枯燥了,因此必须抓住某一方面来提起学生的兴趣。所以在教学上必须让学生自己找到感兴趣的问题加以提炼。故,在教法上我多用默读,让学生自己读懂文章,在相对有难度地方采用自主、合作、探 究的方法,使学生在掌握知识的同时,培养其阅读说明文的能力。
一.说教材 1.教材所处的地位《庆祝奥林匹克运动复兴25周年》是人教版部编初中语文教材八年级下册第四单元“思想光芒”中的一篇经典演讲词。它是同学们接触过《 最后一次讲演》《应有格物致知精神》《我一生中的重要抉择》,初步了解、掌握关于演讲的一些技巧之后,再次让学生倾听那些穿越时空的声音,感受演讲精品的魅力,并总结、借鉴典范演讲的经验,在历练中提高演说才能。因为在现代社会中,良好的口语交际能力是公民的重要素养之一,它不但显示着一个人的语言水平,更体现着一个人的自信、智慧、教养与风度。2.教材分析 《庆祝奥林匹克运动复兴25周年》是顾拜旦于1919年4月在瑞士洛桑庆祝奥林匹克运动恢复25周年纪念会上的演说,是关于奥林匹克运动的重要文献。顾拜旦用诗歌般的语言阐述了奥林匹克精神的内涵与价值;以饱含喜悦的神情引领听众去联想奥林匹克精神无限美好的前景。这篇演说词和他的诗歌《体育颂》一起成为世界文化史和体育史上不朽的篇章。
设计意图:知识的掌握需要由浅到深,由易到难.我所设计的三个例题难度依次上升,根据由简到难的原则,先让学生学会熟悉选用公式,再进一步到公式的变形应用,巩固知识.特别是第三题特别强调了运用法则的前提:必需要底数相同.为加深学生对法则的理解记忆,形成“学以致用”的思想.同时为了调动学生思考,接下来让学生进入反馈练习阶段,进一步巩固记忆.4、知识反馈,提高反思练习1(1)口答设计意图:根据夸美纽斯的教学巩固性原则,为了培养学生独立解决问题的能力,在例题讲解后,通过让个别同学上黑板演演,其余同学在草稿本上完成练习的方式来掌握学生的学习情况,从而对讲解内容作适当的补充提醒.同时,在活动中引起学生的好奇心和强烈的求知欲,在获得经验和策略的同时,获得良好的情感体验.
4、巩固新知,拓展新知(羊羊竞技场)本环节在学生对性质基本熟悉后安排了四组训练题,为避免学生应用性质的粗糙感,以小羊展开竞技表演为背景,让学生在轻松愉快的氛围中层层递进,不断深入,达到强化性质,拓展性质的目的。提高学生的辨别力;进一步增强学生运用性质解决问题的能力;训练学生的逆向思维能力,增强学生应变能力和解题灵活性.5、提炼小结完善结构(羊羊总结会)“通过本节课的学习,你在知识上有哪些收获,你学到了哪些方法?”引导学生自主总结。设计意图:使学生对本节课所学知识的结构有一个清晰的认识,能抓住重点进行课后复习。以及通过对学习过程的反思,掌握学习与研究的方法,学会学习,学会思考。6、课堂检测,发展潜能(大战灰太狼)
情景感知概括运用设疑诱导动手操作合作交流尝试活动启发引导类比发现演练结合观察分析自主探索问题讨论利用尝试活动“我来当老师!”给学生提供设计问题的机会,培养他们实事求是的科学态度,勇于质疑、敢于创新的良好习惯及数学应用能力。例1、根据因式分解的概念,判断下列由左边到右边的变形,哪些是因式分解,哪些不是,为什么?通过罗列一些似是而非、容易产生错误的对象让学生辨析,促使他们认识概念的本质、确定概念的外延,从而形成良好的认知结构。例2:解答下列问题:(1)993-99能被99整除吗?能被98整除吗?能被100整除吗?(2)求代数式IR1+IR2+IR3的值,其中R1=19.2,R2=35.4,R3=32.4,I=2.5。让学生进一步体会用分解因式解决相关问题的简捷性。例3、填空:若x2+mx-n能分解成(x-2)(x-5),则m=,n=。
活动四:自主学习,尺规作图先阅读,再尝试作图,思考作图道理,小组讨论,“为什么作图过程中必须以大于1/2AB的长为半径画弧?”同桌演示尺规作图。最后折纸验证,使整个学习过程更加严谨。我将用下面这个课件给学生展示作图过程。再次回顾情境,让学生完成情境中的问题。(三)讲练结合,巩固新知第一个题目是直接运用性质解决问题,比较简单,面向全体学生。我还设计了第二个题目,想训练学生审题的能力。(四)课堂小结在学生们共同归纳总结本节课的过程中,让学生获得数学思考上的提高和感受成功的喜悦并进一步系统地完善本节课的知识。(五)当堂检测为了检测学生学习情况,我设计了当堂检测。第一个题目,让学生学会转化的思想来解决问题;第二个题目练习尺规作图。
一、教材分析1.教材的地位与作用本节课是在学生学习了三角形的基本概念后,引入图形的全等。这节课探究对象是生活中的常见全等图形,主要是探究全等图形的概念和特征,通过系列学习活动,引导学生体验数学与生活的密切联系,激发学生学习数学的兴趣,培养良好的学习品质。同时这节课的内容也是下一节学习全等三角以及三角形全等的判定的奠基石,它对知识的联系起到承上启下的作用。2.教学目标依据《课程标准》要求本阶段的学生应初步会运用数学的思维方式去观察、分析现实生活中出现的实际问题,体会数学与生活的密切联系,增进对数学的理解和学好数学的信心。因此我确立本节课的教学目标如下:知识技能目标:通过实例,使学生理解图形全等的概念,掌握全等图形的特征,能在不同的图形中识别出全等的图形过程与方法:通过观察,动手实验,培养学生动手操作能力、观察能力以及合作与交流的能力
此题的设计目的:及时的练习一是起到巩固新知识的目的,二是及时了解学生掌握新知识的情况,起到反馈的目的。这样设计的依据是:小题多,是让更多的学生参与到学习中来,及时给予他们更正,更多的是对他们的鼓励和表扬,有简单的题尽量让基础不太好的的学生去说,以让他们感受到成功的乐趣;并且《新课标》中指出课程内容应处于学生“最近发展区”的范围以内,让成功始终伴随学生学习的旅程,以保证学生不会因过多的失败而放弃他们的努力,失去发展的机会。第四环节:师生合作,归纳总结。先由学生个人总结,然后教师补充。设计目的:通过学生个人小结,教师可以了解学生掌握知识的情况,培养学生总结概括的能力,教师补充起到完善所学知识的目的。第五环节:布置作业,巩固提高。设计目的:因材施“作业”,分层次布置作业,减轻学生的负担,全面推行素质教育,让学生学有用的数学,不同的学生学习不同的数学,在数学中得到不同的发展,以求彰显学生的个性。
1.通过实例体会一元一次不等式组是研究量与量之间关系的重要模型之一。2.了解一元一次不等式组及解集的概念。3.会利用数轴解较简单的一元一次不等式组。4.培养学生分析、解决实际问题的能力。5.通过实际问题的解决,体会数学知识在生活中的应用,激发学生的学习兴趣。能在解决问题过程中勤于思考、乐于探究,体验解决问题策略的多样性,体验数学的价值。四、教学重、难点分析教学重点:1.理解有关不等式组的概念.2.会解由两个一元一次不等式组成的不等式组.教学难点:在数轴上确定解集.五、教学手段分析本节课采用多媒体教学,利用多媒体教学信息容量大、操作简单、形象生动、反馈及时等优点,直观地展示教学内容,这样不但可以提高学习效率和质量,而且容易激发学生学习的兴趣,调动积极性。
