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;
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。
学习目标:1、知识与技能(1)会用字母、运算符号表示简单问题的规律,并能验证所探索的规律。(2)能综合所学知识解决实际问题和数学问题,发展学生应用数学的意识,培养学生的实践能力和创新意识。2、过程与方法(1)经历探索数量关系,运用符号表示规律,通过验算验证规律的过程。(2)在解决问题的过程中体验归纳、分析、猜想、抽象还有类比、转化等思维方法,发展学生抽象思维能力,培养学生良好的思维品质。3、情感、态度与价值观通过对实际问题中规律的探索,体验“从特殊到一般、再到特殊”的辩证思想,激发学生的探究热情和对数学的学习热情。学习重点:探索实际问题中蕴涵的关系和规律。学习难点:用字母、运算符号表示一般规律。学习过程:一、创景引入活动:出示一张月历,学生任意选出3×3方格框出的9个数,并计算出这9个数的和,告诉老师,老师就可以说出你所选的是哪9个数。
(1)依照此规律,第20个图形共有几个五角星?(2)摆成第n个图形需要几个五角星?(3)摆成第2015个图形需要几个五角星?解析:通过观察已知图形可得:每个图形都比其前一个图形多3个五角星,根据此规律即可解答.解:(1)根据题意得,第1个图中,五角星有3个(3×1);第2个图中,五角星有6个(3×2);第3个图中,五角星有9个(3×3);第4个图中,五角星有12个(3×4);∴第n个图中有五角星3n个.∴第20个图中五角星有3×20=60个.(2)摆成第n个图形需要五角星3n个.(3)摆成第2015个图形需要6045个五角星.方法总结:此题首先要结合图形具体数出几个值,注意由特殊到一般的分析方法.此题的规律为摆成第n个图形需要3n个五角星.三、板书设计教学过程中,强调学生自主探索和合作交流,经历观察、操作、验证、归纳、分析、猜想、抽象、积累、类比、转化等思维过程,从中获得数学知识与技能,体验教学活动的方法,同时升华学生的情感态度和价值观.
煤的价格为400元/吨,生产1吨甲产品除需原料费用外,还需其他费用400元,甲产品每吨售价4600元;生产1吨乙产品除原料费用外,还需其他费用500元,乙产品每吨售价5500元.现将该矿石原料全部用完,设生产甲产品x吨,乙产品m吨,公司获得的总利润为y元.(1)写出m与x的关系式;(2)写出y与x的函数关系式.(不要求写自变量的取值范围)解析:(1)因为矿石的总量一定,当生产的甲产品的数量x变化时,那么乙产品的产量m将随之变化,m和x是动态变化的两个量;(2)题目中的等量关系为总利润y=甲产品的利润+乙产品的利润.解:(1)因为4m+10x=300,所以m=150-5x2.(2)生产1吨甲产品获利为4600-10×200-4×400-400=600(元);生产1吨乙产品获利为5500-4×200-8×400-500=1000(元).所以y=600x+1000m.将m=150-5x2代入,得y=600x+1000×150-5x2,即y=-1900x+75000.方法总结:根据条件求一次函数的关系式时,要找准题中所给的等量关系,然后求解.
8.一束光线从点A(3,3)出发,经过y轴上点C反射后经过点B(1,0)则光线从A点到B点经过的路线长是( )A.4 B.5 C.6 D.7第四环节课堂小结1、关于y轴对称的两个图形上点的坐标特征:(x , y)——(- x , y)2、关于x轴对称的两个图形上点的坐标特征:(x , y)——(x , - y)3、关于原点对称的两个图形上点的坐标特征:(x , y)——(- x , -y)第五环节布置作业习题3.5 1,2,3四、 教学反思通过“坐标与轴对称”,经历图形坐标变化与图形的轴对称之间的关系的探索过程, 掌握空间与图形的基础知识和基本技能,丰富对现实空间及图形的认识,建立初步的空间观念,发展形象思维,激发学生对数学学习的好奇心与求知欲,学生能积极参与数学学习活动;积极交流合作,体验数学活动充满着探索与创造。教学中务必给学生创造自主学习与合作交流的机会,留给学生充足的动手机会和思考空间,教师不要急于下结论。事先一定要准备好坐标纸等,提高课堂效率。
解析:从各点的位置可以发现A1(1,0),A2(1,1),A3(-1,1),A4(-1,-1),A5(2,-1),A6(2,2),A7(-2,2),A8(-2,-2),A9(3,-2),A10(3,3),A11(-3,3),A12(-3,-3),….仔细观察每四个点的横、纵坐标,发现存在着一定规律性.因为2015=503×4+3,所以点A2015在第二象限,纵坐标和横坐标互为相反数,所以A2015的坐标为(-504,504).故填(-504,504).方法总结:解决此类题常用的方法是通过对几种特殊情况的研究,归纳总结出一般规律,再根据一般规律探究特殊情况.三、板书设计轴对称与坐标变化关于坐标轴对称作图——轴对称变换通过本课时的学习,学生经历图形坐标变化与图形的轴对称之间的关系的探索过程,掌握空间与图形的基础知识和基本作图技能,丰富对现实空间及图形的认识,建立初步的空间观念,发展形象思维,激发数学学习的好奇心与求知欲.教学过程中学生能积极参与数学学习活动,积极交流合作,体验数学活动的乐趣.
一、导入新课在《摔跤吧!爸爸》这部电影中,男主角阿米尔·汗为塑造形象先增肥28公斤再暴瘦25公斤,只为了拍好适应不同年龄的角色。不过,为了一部电影付出如此努力,你们觉得是否有此必要呢?(引导学生稍做讨论)是的,有必要,因为这正是他敬业精神的体现,正是他的敬业精神,让他的电影一次次取得成功。敬业,不仅是阿米尔·汗独有的话题,在近代,我国思想家梁启超就已经很深入地探讨了敬业甚至乐业的重要性。今天,就让我们一起学习这位思想家的演讲稿——《敬业与乐业》,在感知先哲思想风采中,去观照自己的学习精神和生活态度,领悟人生价值。二、教学新课目标导学一:认识作者作者简介:梁启超(1873—1929),近代思想家,著名学者。字卓如,号任公,别号饮冰室主人。广东新会人。与其师康有为一起领导了“戊戌变法”。他兴趣广泛,学识渊博,在文学、史学、哲学、佛学等诸多领域都有较深的造诣。他一生著述宏富,所遗《饮冰室合集》计148卷,1000余万字。
一、复习回顾、引入新课上节课,我们学习了《怀疑与学问》的内容,也学习了议论文结构的基本特征以及常用的论证方法,这节课我们重点学习议论文在论证论点过程中说理的层次,还要进一步理解议论文分析事理透辟,语言严密的特点。二、教学新课目标导学一:探究说理的层次,明确各段之间的关系请同学们细读课文,边读边思考句与句之间的关系,分组完成以下问题。1.本文论点是“治学必须有怀疑精神”,作者是如何阐述怀疑精神的?明确:对怀疑精神作者阐述得明确而透彻:所谓疑就是决不轻信,经过思考,分清是非,再决定信与不信;进而把怀疑科学地分为“怀疑”“思索”“辨别”三步。2.结合课文思考:作者是如何阐述“从怀疑到创新”这一治学过程的?明确:作者在进一步论证“怀疑是建设新学说、启迪新发明的基本条件”时,又把怀疑到创新的治学过程分析为“怀疑、辩论、评判、修正、创新”。作者通过举例、正反说理,使内容阐述得鞭辟入里,无懈可击。
上一周因为值周,就比平时多了一分认真和仔细。每日里来来回回校园、教室、和学生公寓数次,总以为能捡拾一些野蛮和污渍、懒惰和诡异,每日里去,每日里来,一周下来却一无所擒。然而,大失所望之余有所获,那就是,文明如美丽之花,炫耀夺目,在校园四处绽放!以前,与同事聊天论谈,总爱把行知学校之旅娓娓道来,什么校园洁净得让你不得不把唾沫往肚里咽;学生文明得让你点头点得头发酸;教师热辣得让你坐立不安心发软。而今在咱们的校园里,无论是在校外还是校园内;无论是在楼道还是走廊上;无论是熟悉的还是不熟悉的,十之八九那一声声“老师好”,在你不断地点头和回复中,分明also会感受到那一丝丝的骄傲和自豪。心绪如美丽之花,被这暖洋洋的问候日益滋润而绚丽绽放。当你行走在初二年级走廊的时候,你总有一种不一样的感觉。干净明洁的走廊,每天总有那么一块磨石地板熠熠生辉,铮铮发亮,美丽的磨石,不,是美丽的宝石,是吴书平老师辛勤劳作,率先垂范,为人师表的一块瑰宝,我们不得不说,吴老师,向你敬礼,你辛苦了!也许,正是因为你,校园因此而美丽,文明因此而灿烂,谢谢你,吴老师!
