The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2. Use the structure of the reading article and language.
Listening and Speaking introduces the topic of “talking about how to become an astronaut”. This period is aimed to inform students some details about the requirements of being an astronaut. Students can be motivated and inspired by the astronauts. Teachers ought to encourage students to learn from them and let them aim high and dream big.Listening and Talking introduces the theme of "talk about life in space". This part also informs students more details about life in space and can inspire students to be curious about this job. 1. Guide students to listen for numbers concerning dates, years and ages etc2. Cultivate students' ability to talk about how to become an astronaut and life in space ; 3. Instruct students to use functional sentences of the dialogue such as “ first of all, I am not sure, so what might be .. I guess.. I wonder…I am curious…)appropriately.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to become a qualified astronaut and describe the life in space.Part 1: Listening and SpeakingStep 1: Lead inPredictionThe teacher can ask students to predict what the listening text is about by looking at the pictures.About how to become an astronaut./the requirements of an astronautStep 2: Then, play the radio which is about an interview a. And after finishing listening for the first time, the students need to solve the following tasks.
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

另一方面,其余的人反对这个计划,因为它可能会导致一些不好的影响。7.I hold the belief that space exploration not only enable us to understand how the universe began but also help us survived well into the future.我坚信探索太空不仅能够使我们了解宇宙的起源而且能够帮助我们更好地走进未来。8.I think we should spend more time and money exploring space so as to provide new and better solutions to people's shortterm and longterm problems.为了给人类的短期和长期问题提供更新和更好的解决方法,我认为我们应该花更多的时间和金钱来探索太空。9.From my point of view,it is wrong of young people to depend on their telephones too much,which may do harm to both their physical and mental health.在我看来,年轻人过度依赖手机是不对的,因为它们可能会对他们的身心健康都有害。最近你班同学就“人类是否应该进行宇宙探索”这个问题进行了激烈的讨论。有人认为,探索宇宙不仅让人类更好地了解宇宙的发展,还可以用来指导农业生产,以及把一些探索太空的高新技术用于现实生活;也有一些人认为探索太空花掉了大量的人力物力;影响了人们的生活水平。请你根据以下情况写一篇报告并发表自己的观点。注意:1.写作内容应包括以上全部要点,可适当发挥,使上下文连贯;
《小狗学叫》这篇童话通过拟人的手法,叙述的是一只小狗学叫的故事。构思新颖,想象丰富,作者的情思寄寓在形象的描写中,耐人寻味。故事读起来看似有点荒诞无稽,但细品之后谁也不会去怀疑和谈论故事的真实性,而是深刻地思考品评故事所暗示的“小狗终于做成真正的狗,找回迷失的自我”的主题。作者曾经说过:“在每一件事物中都有一个故事,这些故事在桌子的木头中,在玻璃中,在玫瑰中……” 《小狗学叫》正是以现实生活为基础,在每一件事中挖掘故事,把现实世界的偶然现象和必然因素统一起来,把故事情节的曲折变化和人物性格的逻辑发展结合起来,通过这一高超的艺术辩证法,幽默地展示出现实社会中的某些现象,使人们在笑声中受到教育和启发。我们可用多媒体课件等形象的教学手段,拉近学生与文本之间的距离。 1.会认“讨、厌”等11个生字,读准“吗、担”等5个多音字。2.能预测故事的结局,并将自己的预测与原文进行比较,体会预测的多样性,培养学生听故事的技巧和预测故事结局的能力。3.通过分角色朗读,在观察、想象、表演中,让学生感受阅读的乐趣。4.引导学生正确认识自我,发现自己的潜力,能够做好自己。 1.教学重点:培养学生听故事的技巧和预测故事结局的能力,能根据故事发展寻找推测故事结局的依据。2.教学难点:培养学生认真思考、仔细推敲的探究习惯。 1课时

开门见山,免去了君臣相见的繁文缛节的叙述;“齐人三鼓”一句,就包括了齐军的第一次和第二次击鼓进击而鲁军未出击的过程,也写出了齐军依仗数量上的优势企图取胜的急切心理;两个“可矣”写出了鲁军进军的情况;“辙乱”“旗靡”四个字就概括了齐军溃败的具体情况。文章抛开残酷的战争场面,无一字描写,仅一个“齐师败绩”写明战争结果。多四字句,如“曹刿请见”“牺牲玉帛”“一鼓作气”等,读来典雅端庄,辞约而意丰,言简而意明。疑难探究1.如何理解曹刿以平民身份而主动“论战”的行为?曹刿堪称中国古代平民政治家与军事家。他只是鲁国的一介平民,并非“肉食者”,本无机会参与国家大事的商讨和实施。但他凭借着一颗赤诚的爱国之心,积极参与抵御外敌入侵的政治谋划与军事行动,并创造了以弱胜强的战争奇迹。2.请试着从曹刿、鲁庄公、战争这三个角度分别用四个字对文章每一段内容进行概括。从曹刿的角度可以概括为:曹刿论战—曹刿参战—曹刿释疑。从鲁庄公的角度可以概括为:庄公将战—庄公实战—庄公问因。从战争的角度可以概括为:战前准备—战争过程—战胜原因。
词人如此有违常规,造成了一种拗峭不凡的气势,词意更加纵横驰骋,抒情更加酣畅淋漓。2.如何理解《满江红》(小住京华)中的“俗子”?从这首词的语境来看,“俗子”当指词人的丈夫。这与“八年风味”的婚姻反思,与“青衫湿”的悲情是前后呼应的。秋瑾在后来写的一首《沁园春》中说:“有多少,遇王郎天壤,辜负才华。”在长篇弹词《精卫石》中说:“道韫文章男不及,偏遇个天壤王郎冤不冤。”这些词句,都是借谢道韫所嫁非人,间接抒发了她对婚姻的失望。王郎天壤(天壤王郎),是谢道韫鄙薄她丈夫王凝之的话,出自《世说新语·贤媛》:“一门叔父,则有阿大、中郎;群从兄弟,则有封、胡、遏、末,不意天壤之中,乃有王郎!”当然,从广义上理解,这首词中的“俗人”,也可泛指世俗之人。秋瑾到日本后写的《鹧鸪天》词中,有“祖国沉沦感不禁,闲来海外觅知音”的词句,可见“觅知音”意指寻求救国之道,不一定指个人的情感问题。
预设 对比与映衬、渲染与烘托。由于文章始终是在人物对话中展开的,人物语言和行为遵循“刺激—反应”模式平行而下,自然形成了对比,造成了映衬互见的效果。如围绕易地问题,就有秦王的欲求与安陵君的坚守,有秦王的无理狡辩与唐雎的据理抗争;在意志较量方面,则有“天子之怒”与“布衣之怒”的对垒。秦王所说的“天子之怒”,唐雎的“未尝闻”;唐雎所说的“布衣之怒”,秦王归之于“免冠徒跣,以头抢地”。一个拒绝回答,非常傲气;一个丑化描述,极为轻蔑。这样,人物形象对比鲜明,相互衬托,将一场正义与非正义的较量真实而生动地展现出来。作者为了追求夸张、强化的效果,多借助人物语言渲染气势、烘托气氛,增强故事的“现场感”。如秦王说“灭韩亡魏”,目的是从气势上压倒对手;唐雎罗列刺客的壮举,也表明了血拼到底的气概。秦王先说“灭韩亡魏”,气势夺人;后说“韩、魏灭亡”,辞格已卑。这些生动的描写,极大地凸显了人物性格。
我认识圣陶先生是在成都,1941年春天的一个细雨蒙蒙的上午。那时候我在华西大学中国文化研究所工作,圣陶先生在四川省教育科学馆工作。教育科学馆计划出一套供中学语文教师用的参考书。其中有一本《精读指导举隅》和一本《略读指导举隅》,是由圣陶先生和朱佩弦先生合作编写的。计划里边还有一本讲文法的书,圣陶先生从顾颉刚先生那里知道我曾经在云南大学教过这门课,就来征求我的意见,能否答应写这样一本书。我第一次见到圣陶先生,跟我想象中的“文学家”的形象全不一样:一件旧棉袍,一把油纸雨伞,说话慢言细语,像一位老塾师。他说明来意之后,我答应试试看。又随便谈了几句关于语文教学的话,他就回去了。那时候圣陶先生从乐山搬来成都不久,住家和办公都在郊外。过了几天,他让人送来一套正中书局的国文课本,供我写书取用例句。
《核舟记》是一篇说明性质的文言文,作者在完整而深刻地理解雕刻艺术构思的基础上,合理安排材料,运用简练生动的文字再现了“核舟”的形象。本课教学设计,注重学生自主学习、自主探究、自主拓展,教师予以有效指导。教学中的各个环节环环相扣,思路清晰。在自主学习的过程中,掌握文章的基本内容;在合作学习的过程中,完成文言知识卡片的归纳整理;在探究学习的过程中,通过“找一找”“品一品”两个环节,让学生深入到文本中进行赏析,感知核舟的奇巧,感悟雕刻者技艺的精巧和构思的精妙,学习作者行文的巧妙,体会到文章语言的简洁、准确和生动;在布置作业环节,联系课堂内外,有拓展延伸的阅读,有学以致用的练笔。整个教学设计适应了学生各种能力的发展需要,提高了学生的语文素养。疑难探究《核舟记》一般被视为说明文,但文中包含了大量的描写。对此应该如何理解?首先,说明文是今天我们按照记叙文、说明文、议论文三大文体分类为之做出的界定,而古人的文体分类中并无“说明文”一类,《核舟记》这种记物之文和记游、记亭台楼阁之文都属于“杂记”。
(1)看题目。题目中蕴含着诸多信息,如时间、地点、人物、事件以及诗人的心情、诗歌的意境、诗歌的类型等。抓住这一切入点,有助于我们理解诗歌的思想感情。(2)看作者。作品是作者思想情感的具体化,所以,要准确理解诗词,把握作品的思想感情,就不能脱离作者孤立地臆断。作者的生平、写作风格、思想等等,无不影响着作者的情绪,所以,在鉴赏作品时,首先要了解作者的相关背景等。(3)看时代。把握时代风貌特征,把诗歌放在时代背景下评析,才能准确领悟其蕴含的思想感情。(4)看意象。诗歌的创作讲究含蓄、凝练。诗人的抒情往往不是情感的直接流露,而是注重弦外之音、言外之意。写景则借景抒情,咏物则托物言志。因此意象也就是作者的主观感情与客观物象的完美结合,是诗人情感显现的载体。把握诗中的意象,就能参悟意境,理解诗中蕴含的情感。
第二,《战国策》描写人物的性格和活动更加具体细致,也就更显得生动活泼。《左传》描写人物,大抵是简笔勾勒。第三,《战国策》所记的策士说辞,常常引用生动的寓言故事,这也是以文学手段帮助说理的方法。这些寓言,形象鲜明,寓意深刻,又浅显易懂,独立地看也是中国文学宝库中的璀璨明珠。疑难探究除了高超的语言艺术,邹忌劝谏成功还有哪些重要因素?除了高超的语言艺术,邹忌能劝谏成功,还有其他重要的因素。比如:这也与邹忌善于思考、分析的个性和他的担当、责任意识相关。邹忌关心国家大事,一心想寻找恰当时机劝谏齐王。他在生活中经历了“比美”经历,能够深入思考、分析,体察各人的情状心理,并敏锐地由个人体验联系到国家大事,想到齐王所受之蔽,于是果断地进行劝谏。这也离不开齐王广开言路的胸襟和果断行事的理政智慧。齐王听了邹忌的劝谏,马上“下令”,并且分上、中、下三种不同层面赏赐,立刻实施,表现出一位贤明君主的特点。
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。
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
