本篇故事虽短,但记述简洁生动,情趣盎然,人物形象鲜明,哲理深入浅出,是学生了解传统文化,学习浅易文言文,增强文言语感的经典文言小品文。所以本教学设计首先注重落实字词基础;然后用抢答的方式帮助学生理解课文内容;再以人物为核心,细读课文,通过表演的方式,抓住重点实词、虚词,揣摩人物的心理和个性特点,了解文言语言简洁精练的特点,激发学生学习文言文的兴趣。通过质疑探究,走进文本背后,引导学生学习探究文言故事的方法,培养学生独立思考、质疑探究的能力。文学知识笔记体小说笔记体小说指具有小说性质,介于随笔和小说之间的一种文体,是中国古典小说的一种。笔记体小说多以人物趣闻逸事、民间故事传说为题材,具有写人粗疏、叙事简约、篇幅短小,形式灵活、不拘一格的特点。笔记体小说的起源可以追溯到南朝刘义庆的《世说新语》。代表作有清代纪昀的《阅微草堂笔记》等。
【设计意图】本环节既总结了学习的内容,也拓展了文章的主题;引导学生理解长征精神在当今时代的作用、意义,并传承长征精神,接受革命传统教育。四、总结存储1.教师总结。文章在叙述红军翻越老山界的经过中,进行了富有抒情气息的描写,展现了红军伟大的精神力量,也让我们感受到了长征岁月中浪漫的英雄情怀。岁月沧桑,斗转星移,中国已发生翻天覆地的变化,长征精神亦成为中华民族的宝贵精神财富。年轻一代的我们,应坚定信念,弘扬长征精神,为中华民族的伟大复兴而努力,弹奏新征途的“天籁之音”。2.布置作业。(1)课外选读:《大渡河畔英雄多》(杨得志)、《越过夹金山,意外会亲人》(杨成武)。(2)以小组为单位编写一期有关长征精神的手抄报,参加班级展示活动。
素养提升作文中怎样运用“以小见大”的写作手法(1)以小人物见大。这里的“小人物”是指在社会上不出名、没有影响的人。以小人物见大,即以生活中平凡的小人物为叙写对象,通过塑造小人物的形象,揭示其闪光的品质,彰显其伟大的人格,折射出底层人民的光芒,喻人以大道理,动人以大感情,从而起到激励、感化读者的大作用。(2)以小事见大。可以通过叙写生活中极其平常的小事阐述一个大的道理。文化常识典故故事——君子之交“君子之交”语出《庄子·山木》:“且君子之交淡若水,小人之交甘若醴;君子淡以亲,小人甘以绝。”君子之交,意思是贤者之间的交情,平淡如水,不尚虚华。唐贞观年间,薛仁贵尚未得志之前,与妻子住在一个破窑洞中,衣食无着落,全靠王茂生夫妇接济。后来,薛仁贵参军,在跟随唐太宗李世民御驾东征时,立下汗马功劳,被封为“平阳郡公”。一登龙门,身价百倍,前来送礼祝贺的文武大臣络绎不绝,可都被薛仁贵婉言谢绝了。
同学们,你们知道,3月12日是什么节日吗?(植树节)目前全世界有50多个国家规定了植树节,各个国家由于气候的不同,植树的节日各不相同,每年的3月12日是中国的植树节。3月12日是孙中山先生逝世纪念日。孙中山先生生前十分重视林业建设。1979年2月,国务院将孙中山先生与世长辞之日定为中国植树节,是为了缅怀孙中山先生的丰功伟绩,象征中山先生生前未能实现的遗愿将在新中国实现并且要实现得更好。树木为人类提供氧气,在光合作用下会释放清新的氧气,让我们自由的呼吸;树木能美化环境,因为每一棵树都是一处风景;树木可以净化空气,把人类活动产生的有害气体及粉尘进行吸附;树木能够防止水土流失,能够防风固沙,总之树木是人类的朋友,对人类大有裨益。生存与发展是人类必须面对的永恒题材。一味地发展,单纯的追求经济,导致的是环境的恶变,牺牲的是人类的健康,这种赚足今天、不管明天的发展模式后果极其严重。土壤、河流、天空、海洋伤痕累累,人类怎样对待自然,自然会怎样对待人类。
民族精神是一个民族赖以生存和发展的精神支撑。一个民族,没有振奋的精神和高尚的品格,不可能自立于世界民族之林。“铁人”精神是“爱国、创业、求实、奉献”的大庆精神的典型化、人格化。其主要方面包括:“为祖国分忧、为民族争气”的爱国主义精神;为“早日把中国石油落后的帽子甩到太平洋里去”,“宁肯少活二十年,拼命也要拿下大油田”的忘我拼搏精神;干事业“有条件要上,没有条件创造条件也要上”的艰苦奋斗精神;“要为油田负责一辈子”,“干工作要经得起子孙万代检查”,对工作精益求精,为革命“练一身硬功夫、真本事”的科学求实精神;不计名利,不计报酬,埋头苦干的“老黄牛”精神;等等。40多年来,“铁人”精神早已家喻户晓,深入人心,成为大庆人的共同理想、信念和行为准则。“铁人”精神是对王进喜崇高思想、优秀品德的高度概括,体现了我国工人阶级精神风貌和中华民族传统美德的完美结合。“铁人”精神是战胜困难、勇往直前、不断取得新胜利的巨大精神力量。“铁人”精神是我们强大的精神支柱。
陶弘景隐居茅山时期,仍然关心社会的发展,希望社会稳定,天下百姓都能安居乐业。梁武帝很感激陶弘景给予的有力支持,亲提御毫,写了一封情真意切的御诏,文曰:“山中何所有?卿何恋而不返?”盼望陶弘景出山辅政,重列朝班。然而陶弘景下定了不出山的决心,他先写了一首诗,后画了一幅画作为回答。诗为《诏问山中何所有赋诗以答》:“山中何所有,岭上多白云。只可自怡悦,不堪持赠君。”画的内容是:两头牛,一头散放水草之间,自由自在;一头套着金笼头,被人用牛绳牵着,用牛鞭驱赶。梁武帝看了诗和画,领会了他的用意,就不再强迫他出来做官了。但是“国家每有吉凶征讨大事,无不前以咨询”,故当时人称陶弘景为“山中宰相”。林语堂《苏东坡传》中这样评价苏轼
师:既然活得这么痛苦,为什么罗素说是“值得”的?预设 (1)罗素胸怀广阔,勇于担当,要为解除天下百姓的苦难而活着,因此付出辛苦是值得的;(2)罗素不以苦为苦,而以苦为乐,因此痛苦的生活是值得的;(3)苦中伴随着乐,例如爱情会带来欢愉,同时征服了苦难也会产生胜利的喜悦,因此苦乐相伴的体验是值得的;(4)虽然罗素最终没能减轻人类的不幸,甚至自己也深受其害,但毕竟努力过,奋斗过,这一切都是值得的。2.思维拓展师:像罗素一样心忧天下的人还有很多,你想到了谁?课件出示:屈原:长太息以掩涕兮,哀民生之多艰。杜甫:安得广厦千万间,大庇天下寒士俱欢颜!范仲淹:先天下之忧而忧,后天下之乐而乐。阿诺德:“同情,使软弱的人觉得这个世界温柔,使坚强的人觉得这个世界高尚。”……师小结:罗素追求爱情、知识、同情心,作为中学生的我们更应该有自己的追求。我们的追求要有利于社会的发展,要符合社会的进步要求,这样,我们的追求才会更有意义。【设计意图】设计此环节,一是为了深化对本文的理解,二是让学生思维拓展延伸,联想更多与罗素类似同情人类苦难的人,培养学生正确的人生观,用榜样去影响学生。【板书设计】

二、探究新知一、空间中点、直线和平面的向量表示1.点的位置向量在空间中,我们取一定点O作为基点,那么空间中任意一点P就可以用向量(OP) ?来表示.我们把向量(OP) ?称为点P的位置向量.如图.2.空间直线的向量表示式如图①,a是直线l的方向向量,在直线l上取(AB) ?=a,设P是直线l上的任意一点,则点P在直线l上的充要条件是存在实数t,使得(AP) ?=ta,即(AP) ?=t(AB) ?.如图②,取定空间中的任意一点O,可以得到点P在直线l上的充要条件是存在实数t,使(OP) ?=(OA) ?+ta, ①或(OP) ?=(OA) ?+t(AB) ?. ②①式和②式都称为空间直线的向量表示式.由此可知,空间任意直线由直线上一点及直线的方向向量唯一确定.1.下列说法中正确的是( )A.直线的方向向量是唯一的B.与一个平面的法向量共线的非零向量都是该平面的法向量C.直线的方向向量有两个D.平面的法向量是唯一的答案:B 解析:由平面法向量的定义可知,B项正确.
二、探究新知一、点到直线的距离、两条平行直线之间的距离1.点到直线的距离已知直线l的单位方向向量为μ,A是直线l上的定点,P是直线l外一点.设(AP) ?=a,则向量(AP) ?在直线l上的投影向量(AQ) ?=(a·μ)μ.点P到直线l的距离为PQ=√(a^2 "-(" a"·" μ")" ^2 ).2.两条平行直线之间的距离求两条平行直线l,m之间的距离,可在其中一条直线l上任取一点P,则两条平行直线间的距离就等于点P到直线m的距离.点睛:点到直线的距离,即点到直线的垂线段的长度,由于直线与直线外一点确定一个平面,所以空间点到直线的距离问题可转化为空间某一个平面内点到直线的距离问题.1.已知正方体ABCD-A1B1C1D1的棱长为2,E,F分别是C1C,D1A1的中点,则点A到直线EF的距离为 . 答案: √174/6解析:如图,以点D为原点,DA,DC,DD1所在直线分别为x轴、y轴、z轴建立空间直角坐标系,则A(2,0,0),E(0,2,1),F(1,0,2),(EF) ?=(1,-2,1),
