【教学目标】1.熟读全文,掌握文中出现的重要的实词、虚词、古汉语句式;2.鉴赏本文融情于事的表达和形象精粹的语言;3.深入体会文章凄切婉转的陈情技巧。【教学重点】重要的古汉语语词知识【教学难点】理解作者当时的处境和李密祖孙间真挚深厚的感情【教学方法】作为教读课,选择串讲的方式,突出朗读,以期能做到既落实知识,又能体会文章之美。课时安排为两课时。要重点做好预习工作。【教学步骤】一、以苏轼的评论导入读《出师表》不下泪者,其人必不忠;读《陈情表》不下泪者,其人必不孝;读《祭十二郎文》不下泪者,其人必不友二、预习检测1、下列红色字注音完全正确的一项()A、臣以险衅(xìn)夙遭闵(mǐn)凶终鲜(xiǎn)兄弟常在床蓐(rù)B、猥(wěi)以微贱责臣逋(bǔ)慢犹蒙衿(jīn)育宠命优渥(wò)C、岂敢盘桓(huán)有所希冀(yì)日薄(bó)西山除臣洗(xiǎn)马D、逮(dǎi)奉圣朝过蒙拔擢(zhuó)门衰祚(zuò)薄更(gēng)相为命分析:B责臣逋(bū)慢,C有所希冀(jì),D逮(dài)奉圣朝。
【教学目标】1.理解作者反抗黑暗,辞官归田,不与当时黑暗的上层社会同流合污而热爱田园生活的积极精神,学习其高洁的理想志趣和坚定的人生追求。2.掌握“胡、奚、曷、焉、何”五个疑问代词,归纳“行、引、乘、策”等四个词的一词多义,了解“以、而、之、兮、来”等文言虚词的用法。3.背诵全文。【教学重点】1.了解作者辞官归田的原因,深刻体味诗人鄙弃官场,热爱田园的无限欣喜之情。2.背诵全文。【教学难点】1.理解记述中渗透出的或喜或哀,或决绝或犹疑的复杂感情。2.归纳实词、虚词的用法,掌握省略句、倒装句两种句式。【教具准备】投影仪投影胶片【课时安排】2课时【教学过程】第一课时[教学要点]了解陶渊明及其作品。读课文,利用注释、工具书,初步把握文章,朗读课文,找出押韵的字,由押韵归纳各层大意,帮助学生理清背诵思路,背诵全文。[教学步骤]一、导语《桃花源记》是我们在初中接触过的陶渊明的作品。师生一同背诵。《桃花源记》中悠闲自得的田园生活正是作者精神追求的形象反映。今天我们学习的《归去来兮辞》正是作者决别官场,同上层社会分道扬镳的宣言书。
【教学过程】导入:如果说唐诗是中国文学史中的一朵奇葩,那孟浩然则是点缀其上的一滴晶莹露珠,其充满魅力与特色的诗风在盛唐独树一帜,也为其在人才济济的诗史上刻下了永恒的印记。同学们能否先回忆一下,我们学过的孟浩然的诗歌有哪些?(《春晓》、《宿建德江》、《望洞庭湖赠张丞相》、《过故人庄》。)我们常说"中国古诗写胸襟,是人格美的自然流露",那么孟诗在语言和思想情感上留给你怎样的印象和感受?整体感知:本文作者闻一多先生也是一位诗人,所谓"英雄惜英雄",相同的志向与情趣使闻一多似乎带着我们在与孟浩然进行了一场心灵的对话。那么同学们在快速阅读文章之后,能否先找出作者是选择了一个怎样的角度对孟浩然评价的?(诗如其人,人如其诗。)
六、到此为止,我们了解到,作者对“笑”鲲鹏和别人的蜩与学鸠、斥鴳、宋荣子都一一作了否定。那么请大家讨论一下,1、作者对鲲鹏和“知效一官,行比一乡,德合一君,而征一国者”是不是肯定呢?明确:也都作了否定。否定后者好理解,关键是否定前者不好理解,因为“鲲鹏展翅”早已作为积极的意象被人们广泛引用。但在本文中,作者在讲述这一寓言故事时,突出的不是鲲鹏本身,而是风力,“故九万里,风斯在下矣,而后乃今培风;背负青天,而莫之夭阏者,而后乃今将图南”。对风力作用的突出,实际上就是对鲲鹏的否定。作者写了“笑”的双方,对“笑”的一方蜩与学鸠、斥鴳、宋荣子都作了否定,对被“笑”的一方鲲鹏和“知效一官,行比一乡,德合一君,而征一国者”也都作了否定,并且对顺便提及的野马、尘埃、芥、大舟、朝菌、蟪蛄、冥灵、大椿、彭祖、列子等事物或者人物也都作了否定。这种全盘否定的态度,如果我们借用本文中的一个形象的词语,可以说是:笑!是的,本文也可以说是:庄子“笑”万物!
一般情况下,凡是支持物对物体的支持力,都是支持物因发生形变而对物体产生弹力。所以支持力的方向总是垂直于支持面而指向被支持的物体。例1:放在水平桌面上的书书由于重力的作用而压迫桌面,使书和桌面同时发生微小形变,要恢复原状,对桌面产生垂直于桌面向下的弹力f1,这就是书对桌面的压力;桌面由于发生微小的形变,对书产生垂直于书面向上的弹力f2,这就是桌面对书的支持力。学生分析:静止地放在倾斜木板上的书,书对木板的压力和木板对书的支持力。并画出力的示意图。结论:压力、支持力都是弹力。压力的方向总是垂直于支持面而指向被压的物体,支持力的方向总是垂直于支持面而指向被支持的物体。引导学生分析静止时,悬绳对重物的拉力及方向。引导得出:悬挂物由于重力的作用而拉紧悬绳,使重物、悬绳同时发生微小的形变。重物由于发生微小的形变,对悬绳产生竖直向下的弹力f1,这是物对绳的拉力;悬绳由于发生微小形变,对物产生竖直向上的弹力f2,这就是绳对物体的拉力。
一、教材内容经全国中小学教材审定委员会2004年初审查通过,人教育出版社出版的普通高中课程标准实验教科书《物理必修①》,第三章第5节内容“力的分解”。二、教学目标1.知识与技能(1)理解分力的概念,理解力的分解是力的合成的逆运算,遵循平行四边形定则。(2)初步掌握一般情况下力的分解要根据实际需要来确定分力的方向。(3)会用作图法和直角三角形的知识求分力。(4)能区别矢量和标量,知道三角形定则,了解三角形定则与平行四边形定则的实质是一样的。2.过程与方法(1)进一步领会“等效替代”的思想方法。(2)通过探究尝试发现问题、探索问题、解决问题能力。(3)掌握应用数学知识解决物理问题的能力。3.情感态度与价值观(1)通过猜测与探究享受成功的快乐。(2)感受物理就在身边,有将物理知识应用于生活和生产实验的意识。三、教学重点、难点在具体问题中如何根据力的实际作用效果和平行四边形定则进行力的分解。
l.知识与技能:(1)知道摩擦力产生的条件。(2)能在简单问题中,根据物体的运动状态,判断静摩擦力的有无、大小和方向;知道存在着最大静摩擦力。(3)掌握动磨擦因数,会在具体问题中计算滑动磨擦力,掌握判定摩擦力方向的方法。(4)知道影响到摩擦因数的因素。2.过程与方法:通过观察演示实验,概括出摩擦力产生的条件及摩擦力的特点,培养学生的观察、概括能力。通过静摩擦力与滑动摩擦力的区别对比,培养学生分析综合能力。3.情感态度价值观:在分析物体所受摩擦力时,突出主要矛盾,忽略次要因素及无关因素,总结出摩擦力产生的条件和规律。二、重点、难点分析1.本节课的内容分滑动摩擦力和静摩擦力两部分。重点是摩擦力产生的条件、特性和规律,通过演示实验得出关系f=μN。2.难点是学生有初中的知识,往往误认为压力N的大小总是跟滑动物体所受的重力相等,因此必须指出只有当两物体的接触面垂直,物体在水平拉力作用下,沿水平面滑动时,压力N的大小才跟物体所受的重力相等。
1.用CAI课件模拟汽车的启动过程。师生共同讨论:①如果作用在物体上的力为恒力,且物体以匀速运动,则力对物体做功的功率保持不变。此情况下,任意一段时间内的平均功率与任一瞬时的瞬时功率都是相同的。②很多动力机器通常有一个额定功率,且通常使其在额定功率状态工作(如汽车),根据P=FV可知:当路面阻力较小时,牵引力也小,速度大,即汽车可以跑得快些;当路面阻力较大,或爬坡时,需要比较大的牵引力,速度必须小。这就是爬坡时汽车换低速挡的道理。③如果动力机器在实际功率小于额定功率的条件下工作,例如汽车刚刚起动后的一段时间内,速度逐渐增大过程中,牵引力仍可增大,即F和v可以同时增大,但是这一情况应以二者乘积等于额定功率为限度,即当实际功率大于额定功率以后,这种情况不可能实现。
(五)平抛运动规律的应用例1:一架老式飞机在高出海面45m的高处,以80m/s的速度水平飞行,为了使飞机上投下的炸弹落在停在海面上的敌船,应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。分析:对于这道题我们可以从以下几个方面来考虑:(1)从水平飞行的飞机上投下的炸弹,做什么运动?为什么?(2)炸弹的这种运动可分解为哪两个什么样的分运动?3)要想使炸弹投到指定的目标处,你认为炸弹落地前在水平方向通过的距离与投弹时飞机离目标的水平距离之间有什么关系?拓展:1、式飞机在高出海面45m的高处,以80m/s的速度水平飞行,尾追一艘以15m/s逃逸的敌船,为了使飞机上投下的炸弹正好击中敌船,应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。2、在一次摩托车跨越壕沟的表演中,摩托车从壕沟的一侧以速度v=40m/s沿水平方向向另一侧,壕沟两侧的高度及宽度如图所示,摩托车可看做质点,不计空气阻力。(1)判断摩托车能否跨越壕沟?请计算说明(2)若能跨过,求落地速度?
3.进一步体会力是产生加速度的原因,并通过牛顿第二定律来理解匀速圆周运动、变速圆周运动及一般曲线运动的各自特点。(三)、情感、态度与价值观1.在实验中,培养学生动手、探究的习惯。2.体会实验的意义,感受成功的快乐,激发学生探究问题的热情、乐于学习的品质。教学重点1.体会牛顿第二定律在向心力上的应用。2.明确向心力的意义、作用、公式及其变形,并经行计算。教学难点1.对向心力的理解及来源的寻找。2.运用向心力、向心加速度的知识解决圆周运动问题。教学过程(一)、 引入新课:复习提问:匀速圆周运动的物体的加速度——向心加速度,它的方向和大小有何特点呢?学生回答后进一步引导:那做匀速圆周运动物体的受力有什么特点呢?是什么力使物体做圆周运动而不沿直线飞出?请同学们先阅读教材

How do you know?From their wearings, we can know they are from ethnic minority of China--- Miao and Dong.Picture 1, they are playing their traditional instrument lusheng in their traditional costumes.Picture 2. the girls are Miao because they wear their traditional costumes and silver accessory.2. In Picture 3, can you find which village it is? What time is it in the picture?It is Dong village. It is at night. Step 2 While-listeningJustin met a new friend while traveling in Guizhou. Listen to their conversation and complete the summaries below.Part 1Justin and Wu Yue watched some Miao people play the lusheng. The instrument has a history of over 3,000 years and it is even mentioned in the oldest collection of Chinese poetry. Then they watched the lusheng dance. Justin wanted to buy some hand-made silver/traditional accessories as souvenirs. He was told that the price will depend on the percentage of silver. Part 2They will go to a pretty Dong minority village called Zhaoxing. they will see the drum towers and the wind and rain bridges. They may also see a performance of the Grand Song of the Dong people.Step 3 Post-listening---TalkingWork in groups. Imagine Justin is telling some friends about his trip to Guizhou. One of you is Justin and the rest of you are his friends. Ask Justin questions about his trip and experience. The following expressions may help you.
Discuss these questions in groups.Q1: Have you ever been to a place that has a diverse culture ? What do you think about the culture diversity ?One culturally diverse place that I have been to is Harbin, the capital city of Heilongjiang Province. I went there last year with my family to see the Ice and Snow Festival, and I was amazed at how the culture as different to most other Chinese cities. There is a big Russian influence there, with beautiful Russian architecture and lots of interesting restaurants. I learnt that Harbin is called “the Oriental Moscow” and that many Russians settled there to help build the railway over 100 years ago.Q2: What are the benefits and challenges of cultural diversity ?The benefits: People are able to experience a wide variety of cultures, making their lives more interesting, and it can deepen the feelings for our national culture, it is also helpful for us to learn about other outstanding culture, which helps improve the ability to respect others. The challenges: People may have trouble communicating or understanding each other, and it may lead to disappearance of some civilizations and even make some people think “The western moon is rounder than his own.”Step 7 Post reading---RetellComplete the passage according to the text.Today, I arrived back in San Francisco, and it feels good (1) _____(be) back in the city again.
