三、说学情:本课领会方志敏同志清正廉洁这一美德并不困难。但是学生的生活阔别了贫苦,在明白“贫苦”对于革命的意义还会有些空洞化、观点化,这将成为学生学习课文的难点。四、说教法和学法:1.说教法:小组讨论法:针对老师提出的题目,学生举行分组讨论,促使学生在相助中解决题目,培养学生联合协作的能力。朗读感悟法:朗读是一种非常重要的教学要领,课文中方志敏与“士兵”的对话内容以及感情变革写得非常好,很得当,分脚色朗读,在朗读中感觉方志敏同道甘于贫苦、矜持不苟的崇高革命情操。2.说学法:高年级的学生应注意培养学生的自学本领,送还学生自主学习权,我引导学生利用以下要领进行学习:自主探究法、分析归纳法、总结反思法。通过题目导学、学法引导、知识总结等引导学生在课堂上积极学习。
非常清楚,共有6个自然段,第一个自然段是总写手指的特点,2——5自然段是分写五个手指的不同特点,最后一个自然段又总写,点明了文章的中心。文章的语言朴实又富有风趣,采用了拟人化的手法将手指的不同特点写得淋漓尽致。这样的写作顺序及写作方法是学生学习的一个重点。这是一篇略读课文,可用一个课时完成教学。根据以上教材的特点以及新课标所特别关注的学生的“情感态度与价值观、过程与方法、知识与能力”这三个维度的理念,我制定了以下教学目标:1、会读带有拼音的生词,能联系上下文理解词语“窈窕、堂皇、渺小、附庸、养尊处优”的意思;2、能正确、流利、有感情地朗读课文,了解五根手指的不同特点,了解作者描写手指的写作顺序及写作方法。这也是本文的教学重点。3、体会到任何事物都各有所长各有所短的道理,以及团结合作的重要性;这也是本文的教学难点。
一、说教材《跳水》是小学语文五年级下册的一篇精读课文。训练主题是:①抓住文章中的重点词句,体会其表达效果。②揣摩文章表达的顺序,学习基本的表达方法。本单元训练主题与各单元文化主题的融合:抓关键词句,品读文字中的生活,感受生活中智慧的灵光。《跳水》讲述了发生在一艘外国帆船上发生的事. 一只猴子把船长儿子戴的帽子挂到了桅杆顶端最高的横木一头,孩子为了追回帽子,走上橫木,在万分危急的时刻船长急中生智,命令儿子跳水,使孩子转危为安。教材的编排意图是:在读懂课文的基础上,学习船长在危急中,冷静机智和果断处理问题的方法和了解作者记叙一件事情经过的方法。本篇课文情节惊险,扣人心弦,易于激起小学生的阅读兴趣,形象逼真的教材插图给人以身临其境之感。
说明:在帮Li Lei提建议的同时,教育学生如何学好英语。第三课时教学目标1. 语言目标:a) 词汇: Original, in style, haircut, the same as.b) 语言结构:My friend wears the same clothes and has the same haircut as I do.2. 能力目标:大多数学生能够谈论自己喜欢哪种服装,提高查找信息的能力。3. 情感目标:学会如何与朋友相处,要有自己对时尚的看法。教学重点掌握一些重要词汇。教学难点学会谈论问题,并能提出书面建议。◆教学突破首先针对Erin的问题,提出个人的建议,模仿2c部分的对话展开双人交际Pair-work;听老师诵读3a部分的信件,并找出LEFT OUT的问题所在;学生完成3b部分的内容,给Left Out提出书面的建议;学以口头形式提出自己目前存在的某个问题,讲给大家听,让同学们给自己提出一个建议,并作笔录;学生两、三个人分成一组,随意性地进行口语交际,谈论P14的第4部分的某个问题,相互交换意见。
Step Ⅱ Show the new words on the screen and teach the new words. Read the new words to students and ask them to repeat.Step Ⅲ 3aThis activity introduces new vocabulary and provides reading practice using the target language.In this activity first look at the four pictures.T: What can you see in the pictures?Ss: Four snow globes.T: Right. There are four snow globes in the pictures. And what are they?Ss: They are a monster, two polar bears, two penguins and a birthday cake.Write these words on the blackboard: snow globe; monster; polar bear; penguin and birthday cake. Read them to the class and ask students to repeat each one. Make sure students understand each word.Use a computer to show the E-mail message on the screen and read the message to students.Get students to read the e-mail on their own, and then draw lines connecting each snow globe and its description.Correct the answers.AnswersA line should connect each snow globe picture with the words that describe it in the letter.Step Ⅳ 3bThis activity provides writing practice using the target language.First review Activity 2a on Page 47.Then ask students to complete the message according to Activity 2a.Some partial sentences are given to students. Write about one person's collection.When students work, walk around the room checking the progress and offering help as needed.When they finish, ask some students to read their messages to the class.
(一).知识方面: 1.培养学生能运用过去进行时来描述、谈论过去某个时间正在发生的事情或动作的意识和能力,能就过去某个时间正在发生的动作做出正确的描述。 2.培养学生的想象力和角色扮演的合作能力。 3.培养学生讲述过去发生的事情经过的能力。能正确运用一般过去时来讲述故事。 (二).技能方面: 1.本单元的语言目标是Talk about past events and tell a story(谈论过去的时间和讲述一个故事),围绕这一目标,要涉及句型: What were you doing when the UFO arrived? ----I was sitting in the barber’s chair. The barber was cutting my hair. 因此必须学习standing、studying、cleaning、sleeping、cooking、making、eating、cutting、等表示地点的词,以便为上述句型提供语言材料。2.学习过去进行时的有关知识。Was/were+现在分词,是该时态的表达式。 3.在学习过程中,要区分The boy was walking down the street when the UFO landed.和While the boy was walking down the street, the UFO landed.这两种由when和while引导的状语从句的句型结构。注意它们的不同。
(1)Have you ever been to …? Yes, I have. / Yes, I have ever been to …No, I haven’t. / No, I have never been to …(2)When did you go there? I went there last year. (3)I have never been to a water park. Neither have I. I have ever been to an amusement park. So have I. (4)How long have you been studying English? I’ve been studying English since nine o’clock. I’ve been studying English since I came back home. I’ve been studying English for five hours. (5)What’s that? It’s an amusement park in Japan. I’ve never been to an amusement park like it before. It’s fun to learn another language. Let’s go tonight. Isn’t this great?space museum, amusement park, water park, South America, Peru, Holland, European culture, tour guide, flight attendant, musical instrument, more than, be from, get to, take lessons, neither, discover, graduate, change
区分宾语从句、定于从句和状语从句宾语从句和状语从句,都叫做主从复合句。宾语从句主要是中考必考的,是初中阶段必掌握的从句,宾语从句主要是掌握三要素,所谓宾语从句,就是宾语在主从复合句当中充当宾语的一个句子,叫做宾语从句。主句的谓语动词是及物动词,后面如果是词或者是短语的话,是简单句,如果是句子的话,肯定是宾语从句。I know that he good at English.就是宾语从句,三要素,一要素是要注意连词,连词一共学了三类连词,一类连词是that口语当中可以省略,就像刚才说的那一句,I hear he is good at English.还有疑问代词、疑问副词,how where when,疑问代词、疑问副词。还有一类连词weather是否的意思,不是状语从句当中的如果,这一定要和如果区分开,这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序,要用陈述举语序。比如说你家有几口人,我们都说How many people are there in you family?但是这是简单句,一旦说成宾语从句,你可以告诉我你家有几口人吗?Could you tell me how many people there are in you family ?
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!欢迎你!请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢?“噢,不!”与陌生人谈话太困难了。但是这也很有意思,并且你还能交到朋友。你该怎么做呢?闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员,不是吗?”“我希望自己能认识她,你呢?“今年的雨水很多,不是吗?”反意疑问句是一种礼貌用语。为了使得谈话成功,你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧,下次在英语课上,你会发现与大家展开谈话是一件很容易的事情,不信我们来试试。)

一、说教材《赠刘景文》这首古诗的作者是苏轼。这首古诗是写秋末的景色,第一句以荷败、菊残,写出了秋末的特征。接下来诗人以橙子的金黄与橘子的青绿,把深秋的景色点缀得色彩鲜明而富有生气。诗人在此一反悲秋的调子,突出了秋天是收获的季节。第二行诗赞颂了菊花的残枝有傲霜凌寒的气概。二、说教学目标1.学会本课生字,重点理解诗句中“擎、残、犹”的意思。了解诗句的含义。2.能正确、流利、有感情地朗读古诗和背诵古诗。3.通过对诗句的诵读感悟,培养学生丰富的想象力和语言表达能力。体会诗中描绘的浓浓秋色,感受诗歌美的意境和深刻的哲理。4.通过学习课文,唤起学生面对生活要乐观向上,不泄气,珍惜现在的大好时光。三、教学重、难点1.通过“欣赏意境”的训练和利用画面再现,从词义理解到理解全句、全篇,来帮助学生领悟、感受全文。(重点)2.通过对诗句的诵读感悟,培养学生丰富的想象力和语言表达能力。体会诗中描绘的浓浓秋色,感受诗歌美的意境和深刻的哲理。(难点)
从而为列方程找等量关系作了铺垫.环节2中的表格发给每个小组,为增强小组讨论结果的展示起到了较好的作用.环节3中通过让学生自己设计表格为讨论的得出起到辅助作用.2.相信学生并为学生提供充分展示自己的机会本节课的设计中,通过学生多次的动手操作活动,引导学生进行探索,使学生确实是在旧知识的基础上探求新内容,探索的过程是没有难度的任何学生都会动手操作,每个学生都有体会的过程,都有感悟的可能,这种形式让学生切身去体验问题的情景,从而进一步帮助学生理解比较复杂的问题,再把实际问题抽象成数学问题.3.注意改进的方面本节课由于构题新颖有趣,所以一开始就抓住了学生的求知欲望,课堂气氛活跃,讨论问题积极主动.但由于学生发表自己的想法较多,使得教学时间不能很好把握,导致课堂练习时间紧张,今后予以改进.
解:设截取圆钢的长度为xmm.根据题意,得π(902)2x=131×131×81,解方程,得x=686.44π.答:截取圆钢的长度为686.44πmm.方法总结:圆钢由圆柱形变成了长方体,形状发生了变化,但是体积保持不变.“变形之前圆钢的体积=变形之后长方体的体积”就是我们所要寻找的等量关系.探究点三:面积变化问题将一个长、宽、高分别为15cm、12cm和8cm的长方体钢坯锻造成一个底面是边长为12cm的正方形的长方体钢坯.试问:是锻造前的长方体钢坯的表面积大,还是锻造后的长方体钢坯的表面积大?请你计算比较.解析:由锻造前后两长方体钢坯体积相等,可求出锻造后长方体钢坯的高.再计算锻造前后两长方体钢坯的表面积,最后比较大小即可.解析:设锻造后长方体的高为xcm,依题意,得15×12×8=12×12x.解得x=10.锻造前长方体钢坯的表面积为2×(15×12+15×8+12×8)=2×(180+120+96)=792(cm2),锻造后长方体钢坯的表面积为2×(12×12+12×10+12×10)=2×(144+120+120)=768(cm2).
(1)本周哪一天河流水位最高,哪一天河流水位最低,它们位于警戒水位之上还是之下,与警戒水位的距离分别是多少?(2)与上周末相比,本周末河流的水位是上升还是下降了?解析:(1)先规定其中一个为正,则另一个就用负表示.理解表中的正负号表示的含义,根据条件计算出每天的水位即可求解;(2)只要观察星期日的水位是正负即可.解:(1)前两天的水位是上升的,第1天的水位是+0.20米;第2天的水位是+0.20+0.81=+1.01米;第3天的水位是+1.01-0.35=+0.66米;第4天的水位是+0.66+0.13=+0.79米;第5天的水位是0.79+0.28=+1.07米;第6天的水位是1.07-0.36=+0.71米;第7天的水位是0.71-0.01=+0.7米;则水位最低的是第一天,高于警戒水位;水位最高的是第5天;(2)+0.20+0.81-0.35+0.13+0.28-0.36-0.01=+0.7米,则本周末河流的水位上升了0.7米.方法总结:解此题的关键是分析题意列出算式,用的数学思想是转化思想,即把实际问题转化成数学问题.探究点二:有理数的加减混合运算在生活中的其他应用
练习:现在你能解答课本85页的习题3.1第6题吗?有一个班的同学去划船,他们算了一下,如果增加一条船,正好每条船坐6人,如果送还了一条船 ,正好每条船坐9人,问这个班共多少同学?小结提问:1、今天你又学会了解方程的哪些方法?有哪些步聚?每一步的依据是什么?2、现在你能回答前面提到的古老的代数书中的“对消”与“还原”是什么意思吗?3、今天讨论的问题中的相等关系又有何共同特点?学生思考后回答、整理:① 解方程的步骤及依据分别是:移项(等式的性质1)合并(分配律)系数化为1(等式的性质2)表示同一量的两个不同式子相等作业:1、 必做题:课本习题2、 选做题:将一块长、宽、高分别为4厘米、2厘米、3厘米的长方体橡皮泥捏成一个底面半径为2厘米的圆柱,它的高是多少?(精确到0.1厘米)
(3)移项得-4x=4+8,合并同类项得-4x=12,系数化成1得x=-3;(4)移项得1.3x+0.5x=0.7+6.5,合并同类项得1.8x=7.2,系数化成1得x=4.方法总结:将所有含未知数的项移到方程的左边,常数项移到方程的右边,然后合并同类项,最后将未知数的系数化为1.特别注意移项要变号.探究点三:列一元一次方程解应用题把一批图书分给七年级某班的同学阅读,若每人分3本,则剩余20本,若每人分4本,则缺25本,这个班有多少学生?解析:根据实际书的数量可得相应的等量关系:3×学生数量+20=4×学生数量-25,把相关数值代入即可求解.解:设这个班有x个学生,根据题意得3x+20=4x-25,移项得3x-4x=-25-20,合并同类项得-x=-45,系数化成1得x=45.答:这个班有45人.方法总结:列方程解应用题时,应抓住题目中的“相等”、“谁比谁多多少”等表示数量关系的词语,以便从中找出合适的等量关系列方程.
方法总结:解题关键是要读懂题目的意思,根据题目给出的条件,找出合适的等量关系,列出方程再求解.探究点三:工程问题一个道路工程,甲队单独施工9天完成,乙队单独做24天完成.现在甲乙两队共同施工3天,因甲另有任务,剩下的工程由乙队完成,问乙队还需几天才能完成?解析:首先设乙队还需x天才能完成,由题意可得等量关系:甲队干三天的工作量+乙队干(x+3)天的工作量=1,根据等量关系列出方程,求解即可.解:设乙队还需x天才能完成,由题意得:19×3+124(3+x)=1,解得:x=13.答:乙队还需13天才能完成.方法总结:找到等量关系是解决问题的关键.本题主要考查的等量关系为:工作效率×工作时间=工作总量,当题中没有一些必须的量时,为了简便,应设其为1.三、板书设计“希望工程”义演题目特点:未知数一般有两个,等量关系也有两个解题思路:利用其中一个等量关系设未知数,利用另一个等量关系列方程
