当汽车行驶在乡间小道时,作家冯骥才再也没有了写作的冲动。往日白砖青瓦的农舍冒出了西洋式的尖顶和闪着异光的马赛克,炊烟袅袅,小桥流水成了埋藏在心底的梦。冯先生开始四处奔波,大声疾呼:救救我们的文化遗产!中国文化博大而宽广。她无处不在——融于书本,徜徉于江南小道,盘旋在峭壁飞檐……我们被这种浓厚的文化信息包围着,却道貌岸然地做着刽子手。忘记历史就是背叛。我们的文化遗产是历史的见证。秦始皇的兵马俑至今气宇轩昂地挺立着,隋朝大运河的波澜依旧拍打着千年的岸堤……孟江女的哭声凄婉悲恸,纤夫的号子似乎仍在耳边萦绕。沉淀了千年的沉浮、繁华、屈辱、悲愤,这些文化遗产烫帖了坎坷的心灵,将肃穆呈于世人。刀光剑影去了,长歌悲哭停止了,豪情厮杀消逝了……一切随着大江东去,只有千年松柏和着轻风耳语。

Step 3 (3b)First, tell the students when we talk about our future plans, we often use: I’m+verb+ing When we talk about what we must do, we use have to. Ask the students to fill in the blanks in 3b. The answers are: shopping, go to see, a test, I’m going, my family. Step 4 (3c)Let the students write an e-mail message to a friend. Say why you can’t visit next. Before the exercise, ask the students to give some possible answers and write them on the blackboard. So the students will feel easy to finish the writing exercise. After they finish it, Let them to correct it in groups first. Each group chooses theirs best one to read in front of the whole class. Step 5 ( planning a party )First read the conversation in the box together. Then ask the students to turn to page 88.Write down everything you have to do next week. Write in all the things you have to do . Ask the students to look at the list. Ask them “What day are you free?” This is when you can have your party. Step 6 (Self check 1 )Let the students to fill in the blanks with the words given. Change the forms of the words if possible. Then make their own sentences. The answers are: visit, playing, have to, study, comeStep 7 (Self check 2)Imagine you are Marie. Read the information and look at your schedule. Write replies to the invitation.

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。

“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

教学目标1.知识目标:(1)学习What are you going to be when you grow up?/How are you going to do that?句式。(2)学会用英语描述有关职业的表达法。2.能力目标:(1)能够谈论为实现理想所做出的打算和安排。(2)能够谈论未来自己与他人理想的职业及原因。(3)能用英语描述课余时间的活动安排,最终具备表达综合信息的能力。3.情感目标:新学期到来之际,让他们在学习、体育、饮食、特长、读书等方面制定计划,教育学生合理安排自己的课外生活,思考自己的理想职业及适合自己的职业。教学重点、难点本单元的重点为“be going to”表将来,want to be, what,where, when,how引导的特殊疑问句。难点是语言目标的实现。教材分析本单元以I am going to be a basketball player为话题,共设计了三部分的内容:一、Section A该部分有4个模块。第一模块围绕Do you think these jobs are interesting?这一话题展开思维(1a)、听力(1b)、口语(1c)训练;

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。

(五)教学过程1)在课的开始检查学生对单词短语的掌握2)1b,听力为了让学生了解香蕉奶的制作过程,让学生复述,是为了然他们用所学的重点 词汇进行练习、为后面制作水果沙拉奠定基础。3)2a2b的听力是为了复习how much 与how many的区别 ,因为七年级上册unit8涉及到的知识,所以2a2b训练的的真正目的是为了让学生更清楚的了解不可数名词的表达方式 :数词+量词 +of+不可数名词4)在学生完全弄懂事物的制作过程极其不可数名词的数量表达后,我安排他们进行制作水果沙拉的对话。这个对话是机动的,如果时间充足,我让他们按照自己的医院去选择材料进行对话的编排。这个话题既可以用到本科的重点句型,又可用到重点词汇。在这步抓住重点突出难点5)在consolidate 环节,我安排2个汉译英,4个有关how much/how many 的选择,让学生讲做题原因,让他们彻底弄懂不可数名词的数量表达。6)最后,为了加深学生对食物制作过程描述的巩固,让学生把所学知识从口落实到笔头

3、重点和难点:重点:学会用形容词的最高级来对事物或人物进行描述。难点:形容词的最高级加est还是加most.二、 说教法:为了更好的突出重点,突破难点,我主要采用了:1、任务型教学法:新课标倡导的“玩中学,学中玩”的理念很受学生欢迎。例如,阅读文章时,我设计了一张表格,让学生阅读后完成表格并复述。培养学生逻辑分类与表述能力。2、 竞赛教学法:根据初中生争强好胜的性格特征,我每堂课都进行俩俩对话,激发学生兴趣,给学生创造外语语言氛围,培养学生集体荣誉感。三、说学法:1、 善于抓住用英语交际的机会,充分感知,积极体验,大胆实践。例如在导入新课时的One minute dialogue(每组都有一次机会),pairwork (每人都有机会),groupwork(每组一次机会)。2、 积极参与,善于合作。例如本课设计了几个任务,操作简单,学生一定很感兴趣并且积极参与,从而合作完成任务,培养了团队精神。

根据刚才调查和学生的汇报,我们很自然地可以把调查的内容汇编成一篇口头文章。为了更好的指导学生运用be going to 来进行写作,我们可以把课本上的范文给大家朗读一遍,分析如何来写My dream job.然后,可以当堂让学生模仿来进行一篇作文创造,My dream job.【设计意图】最后的写作环节是本课的提升,学生说的都不错,但落实到笔头,总是会出现这样那样的错误。如何让学生运用be going to 来进行作文创作是我们本课的重点和难点。因此很有必要当堂落实。环节6 Summary学生在老师的指导下进行课堂小结。1.重点句型:2.be going to 的用法。【设计意图】教师引导学生课堂小结,既是对文本内容的复习,又是为下节课打好铺垫,同时充分体现了学生是学习的主体地位,增强了学生自主学习的能力,可谓一举多得。

这一环节我采用电影《哈利波特》中哈利去霍格华兹的图片引入“how does Harry go to school?” 进而引入” how do you go to school?” 呈现“the ways to go to school” 让学生明确take 的使用及与交通工具的搭配。接着让学生根据实际情况回答自己采用的交通方式,期间可以引入“how does he /she go to school?” 基本了解了怎么说后进入课文,完成1a 部分练习 和1 b 的听力练习。完成后让学生玩一个数字游戏,帮学生回忆数字。通过问学生从家里出发时间和到达时间,引出“it takes ?? minutes .” 的句型。借助ppt 图片进行句型操练。然后完成听力练习2a—2c。本环节用时20分钟。While-task:本堂课的主要任务是让学生运用已学的语言知识,完成一个任务,即计算从学校到上海各种交通工具所需要的时间和费用,讨论应选用和种交通工具和各种优缺点。这一环节将用时10分钟。

在任务环活动中,我通过设计不同的四个任务,让学生在小组中交流、合作、竞争,每个任务都存在着一定的“信息差”,易于激发学生的表达欲望和急于知道最终结果的心情,在活动中他们一定会努力表现自己,做到最好。四个任务所侧重的训练学生的语言能力的要求也各有不同,他们分别侧重训练学生的听、说、读、写的能力。把任务活动放在小组中进行,还可以解决“大班”难于操练的难题,学生在小组中有更多的时间来运用英语表达自己的思想。Post-task任务后活动(4”)1. Grammar Focus(2”)Go through the Grammar Focus with the whole class,ask Ss to point out the main points in this period. Then show the use of The Past Tense on the screen, especially the regular and irregular changes of verbs. 2. Language practice(2”)Practise the sentence patterns and the use of the Past Tense, especially the errors which Ss made while carrying out their tasks. Such as Subject-verb agreement or Tense-agreement, etc. For example: were you see any sharks? He go to the beach. 在学生尽情地参与活动后再让学生反思本节课的语法焦点,并进行适当的操练,对学生在任务活动中的语言失误进行纠正,使学生保持学习信心。语法讲解采用动画形式又保持了学生的学习兴趣。

有意义,字母x的取值必须满足什么条件?设计意图:通过例题的讲解,使学生加深对所学知识的理解,避免一些常见错误。而变式练习设计,延续的例题的风格,一步一步,步步深入,本节课的教学难点就在学生的操作活动中迎刃而解了。对提高学生对所学知识的迁移能力和应用意识,激发好奇心和求知欲起到良好效果。(五)、巩固运用,提高认识1、通过基础训练让学生体验学习的成就感。2、应用拓展:增加难处,再次让学生联系以前的知识,增强学生的数学应用意识。(六)、总结评价,质疑问难这节课我们学习了什么?设计意图:学生共同总结,互相取长补短,学生在畅所欲言中对二次根式的认知得到进一步的巩固升华。五、板书设计.采用纲领式的板书,使学生有“话”可说,有“理”可循,在简单板书设计中使学生体会到数学的简洁美。

学生以小组为单位,合作探究蚂蚁爬行的最短路线,充分讨论后,汇总各小组的方案,在全班范围内讨论每种方案的路线计算方法,通过具体计算,总结出最短路线。让学生发现:沿圆柱体母线剪开后展开得到矩形,研究“蚂蚁怎么走最近”就是研究两点连线最短问题,引导学生体会利用数学解决实际问题的方法:建立数学模型,构图,计算.意图:通过学生的合作探究,找到解决“蚂蚁怎么走最近”的方法,将曲面最短距离问题转化为平面最短距离问题并利用勾股定理求解.在活动中体验数学建摸,培养学生与人合作交流的能力,增强学生探究能力,操作能力,分析能力,发展空间观念.3.突破重点、突破难点的策略在教学过程中教师应通过情景创设,激发兴趣,鼓励引导学生经历探索过程,得出结论,从而发展学生的数学应用能力,提高学生解决实际问题的能力.

探究活动二的安排,是要让学生明确只靠实验得出的结论,可能会以点带面,从而进一步说明学习推理的必要性。并小结出:如果要判断一个结论不正确只要举一个反例就可以了。探究活动三的安排是说明只靠实验得出的结论也不可靠,必须经过有根有据的推理才行。活动交流:(1)在数学学习中,你用到过推理吗?(2)在日常生活中,你用到过推理吗?这是一座桥梁,把课堂引向推理的方法。例题的安排,可以让学生学会简单的推理方法,同时增强学生的学习兴趣。课堂练习:①游戏:苹果在哪里?②判断:是谁打破玻璃?把练习变成游戏的形式,也是为了增加课堂的趣味性,提高学生的学习兴趣。课堂小结:进一步明确学习推理的必要性。课后作业:①课本习题6.1:2,3。②预习下一节:定义与命题

我们遇到的往往就是这样的方程组,我们要想比较简捷地把它解出来,就需要转化为同一个未知数系数相同或相反的情形,从而用加减消元法,达到消元的目的.请大家把解答过程写出来.解:①×3,得:6936xy??,③②×2,得:3486??yx,④③-④,得:2?y.将2?y代入①,得:3?x.根据上面几个方程组的解法,请同学们思考下面两个问题:(1)加减消元法解二元一次方程组的基本思路是什么?(2)用加减消元法解二元一次方程组的主要步骤有哪些?(由学生分组讨论、总结并请学生代表发言)[师生共析](1)用加减消元法解二元一次方程组的基本思路仍然是“消元”.(2)用加减法解二元一次方程组的一般步骤是:①变形----找出两个方程中同一个未知数系数的绝对值的最小公倍数,然分别在两个方程的两边乘以适当的数,使所找的未知数的系数相等或互为相反数.②加减消元,得到一个一元一次方程.③解一元一次方程.
