(六)联系实际,在文本体验中获得启发。问题设计:在上面的讨论中,我们对菲利普夫妇的认识更全面了。他们都生活在资本主义社会,那么,现实生活中有菲利普夫妇这样的人吗?你家有于勒这样生活困顿的亲戚吗?你的身边有需要帮助的人吗?你是怎么对待他们的?(多媒体出示问题)这一组问题很能激发学生的兴趣,设计的目的在于教学生学会思考,敢于发表自己的见解,引导学生树立正确的金钱观,不要被现实的金钱关系所异化,不要失去对人的真诚的爱心和同情。这样学校教育的德育目的就达到了。(七)拓展延伸,培养想像力。以“五年后,门铃响了,我去开门,发现正是于勒叔叔……”为开头,试写一段200字左右的文字。(对于这样的一个意外,家人是如何表现,又是如何应对的呢?)
三、说教学重难点1.通过对课文的整体把握和重点词句的理解,了解我国各民族儿童的友爱团结及他们幸福的学习生活,体会贯穿全文的自豪和赞美之情。(重点)2.体会描写窗外的安静和小动物的热闹的句子的表达效果。(难点)四、说教法、学法教无定法,贵在得法,为了突出教学重点,解决教学难点,根据教材特点和学生的年龄特征。我主要采取想象感悟法、朗读感悟法、品词析句法这三种教学方法。运用想象感悟法可以挖掘教材的空白处,开启学生想象的闸门,在研读中通过换位思考体验人物的内心,丰满任务在学生心中的形象,真正做到基于文本又超越文本,同时发展学生的语言和思维;运用朗读感悟法可以以读激情,以读促悟,以情助读,让学生在读中理解感悟;运用品词赏析法可以让学生抓住关键词加以揣摩、推敲、咀嚼,感悟字里行间所蕴含的情感。
(二)过程与方法:1、通过拼读、练习、组词等方法达到正确读写本课生字、新词的目的;2、通过默读、指导感情朗读等多种形式的朗读训练,质疑、讨论、小组合作学习等形式的学习,达到理解含义深刻的句子,体会文章的思想感情的目的;3、通过教师指导、学生独立思考完成填空练习的方法,学习掌握作者抓住人物语言、动作、神态描写表现人物品质的方法。(三)情感、态度与价值观:通过本课的学习,让学生感受鲁迅先生爱憎分明,为自己想得少,为别人想得多的崇高品质,从而激发学生对鲁迅先生的崇敬之情。(四)教学重点:引导学生学习作者抓住人物语言、动作、神态描写表现人物品质的方法。(五)教学难点:理解4句含义深刻的句子,感受鲁迅先生的崇高品质。

一、知识和能力目标通过本单元教学,使学生能运用所学英语,正确地描述物体的颜色;同时进一步学习分辨人物的用语,并加以运用。二、过程和方法目标本单元口语训练应当自始至终在一种鲜明的色彩背景下进行,旨在营造那种为学生所喜爱的欢快气氛,教师应当在十种颜色上大做文章;在使用实物时要使颜色醒目;在组合图画时,要尽量用大色块;在使用投影时要使颜色突出来。教师可以从教室环境上入手营造色彩气氛,如:选取十种颜色的硬色板,剪成各个大写字母;或者将色板剪成各种卡通动物形象,悬挂在教室当中或在墙上,注明各种颜色的英语字块。三、情感态度和价值观目标用各种可以调动学生积极性的活动来提高学生的活跃性,激发他们参与讨论的热情。同时可以对学生进行美育教育,从小培养他们对美的正确认识。
本单元主要学习名词所有格 ('s 所有格 ) 的构成和使用。在初次接触 “ 名词所有格 ” 时,学生较难理解的可能是 “ 所有格 ” 这个名称,对于它的构成,学生也许会觉得较容易。教师可通俗地告诉学生 “ 所有格 ” 的意思是表示 “…… 的 ” ,这样学生反而容易接受。在使用 “ 名词所有格 ” 形式时,学生容易犯错误或混淆的主要是:将这种一 's 构成形式与 is 的缩写形式混淆,如: My father's name's Jin Zhi .,可以这样告诉学生:名词所有格的后面一般应接名词;勿将这种一 's 结构盲目套用与人称代词上,代替物主代词使用,如 He's father's name is Li Cheng 。在教学初期,可不讲授名词所有格的其它形式,待时机成熟,再向学生介绍复数名词所有格形式的结构一 ' ,如: the students' bikes 。 Self Check 教学内容 Self Check( 教材 P52) 教学目标 知识与能力 复习词汇 birthday , date , month , January , February , March , April , May , June , July , August , September , October , November , December , date , birth , age , old , speech . contest . trip , party , event , an , festival , pop , concert , chorus , lecture , music ;引导学生复习、巩固“询问和谈论日期”的目标语言并运用所学知识安排活动。

解析:(1)连接BI,根据I是△ABC的内心,得出∠1=∠2,∠3=∠4,再根据∠BIE=∠1+∠3,∠IBE=∠5+∠4,而∠5=∠1=∠2,得出∠BIE=∠IBE,即可证出IE=BE;(2)由三角形的内心,得到角平分线,根据等腰三角形的性质得到边相等,由等量代换得到四条边都相等,推出四边形是菱形.解:(1)BE=IE.理由如下:如图①,连接BI,∵I是△ABC的内心,∴∠1=∠2,∠3=∠4.∵∠BIE=∠1+∠3,∠IBE=∠5+∠4,而∠5=∠1=∠2,∴∠BIE=∠IBE,∴BE=IE;(2)四边形BECI是菱形.证明如下:∵∠BED=∠CED=60°,∴∠ABC=∠ACB=60°,∴BE=CE.∵I是△ABC的内心,∴∠4=12∠ABC=30°,∠ICD=12∠ACB=30°,∴∠4=∠ICD,∴BI=IC.由(1)证得IE=BE,∴BE=CE=BI=IC,∴四边形BECI是菱形.方法总结:解决本题要掌握三角形的内心的性质,以及圆周角定理.
解析:(1)由切线的性质得AB⊥BF,因为CD⊥AB,所以CD∥BF,由平行线的性质得∠ADC=∠F,由圆周角定理的推论得∠ABC=∠ADC,于是证得∠ABC=∠F;(2)连接BD.由直径所对的圆周角是直角得∠ADB=90°,因为∠ABF=90°,然后运用解直角三角形解答.(1)证明:∵BF为⊙O的切线,∴AB⊥BF.∵CD⊥AB,∴∠ABF=∠AHD=90°,∴CD∥BF.∴∠ADC=∠F.又∵∠ABC=∠ADC,∴∠ABC=∠F;(2)解:连接BD,∵AB为⊙O的直径,∴∠ADB=90°,∴∠A+∠ABD=90°.由(1)可知∠ABF=90°,∴∠ABD+∠DBF=90°,∴∠A=∠DBF.又∵∠A=∠C,∴∠C=∠DBF.在Rt△DBF中,sin∠DBF=sinC=35,DF=6,∴BF=10,∴BD=8.在Rt△ABD中,sinA=sinC=35,BD=8,∴AB=403.∴⊙O的半径为203.方法总结:运用切线的性质来进行计算或论证,常通过作辅助线连接圆心和切点,利用垂直构造直角三角形解决有关问题.
小说精心设计,以“我”回忆往事的视角来叙述,其他人物的态度和行动,都是从“我”的眼里看到的;对其他人物的感受和评述,也都是从“我”的角度表达的。这样写既有利于拉开适当的距离,为小说主题的展开留下空间,同时也有利于安排情节的曲折变化,避免多余的解释说明。【设计意图】内容决定形式,形式服务内容。在逐层深入理解课文时,穿插对写作技巧的讲解与点拨,要求学生在朗读中细细品味,有助于学生深入学习与运用。四、拓展,悟人生1.拓展阅读课外阅读《项链》。2.发散思维有一首歌里唱道:“有钱没钱,回家过年。”假如你是若瑟夫,当你走到于勒面前时,你会对他说些什么呢?【设计意图】学以致用,启迪人生智慧,形成正确的人生观、价值观。结束语:金钱扭曲了人性,撕裂了亲情。观照生活,思索人生,我们会发现亲情带来的温暖远胜于金钱,让我们一起说——让人间充满爱!
教学目标:1.能利用三角函数概念推导出特殊角的三角函数值.2.在探索特殊角的三角函数值的过程中体会数形结合思想.教学重点:特殊角30°、60°、45°的三角函数值.教学难点:灵活应用特殊角的三角函数值进行计算.☆ 预习导航 ☆一、链接:1.如图,用小写字母表示下列三角函数:sinA = sinB =cosA = cosB =tanA = tanB =2. 中,如果∠A=30°,那么三边长有什么特殊的数量关系?如果∠A=45°,那么三边长有什么特殊的数量关系?二、导读:仔细阅读课本内容后完成下面填空:
