人教部编版语文九年级下册曹刿论战教案
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。
人教部编版语文九年级下册词四首教案
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。
人教部编版语文九年级下册梅岭三章教案
（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。
人教部编版语文九年级下册唐雎不辱使命教案
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。
人教部编版语文九年级下册邹忌讽齐王纳谏教案
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。

幼儿园小班科学说课稿 会跳舞的罐宝宝
活动后的反思：在教学中，幼儿对操作、探究很感兴趣，通过操作──游戏的形式让幼儿体会了探究的过程和快乐。在活动中，孩子在制作的同时，提高了幼儿的观察力，动手能力而且也提高了注意力、听觉。他们特别喜欢玩游戏，因为在游戏中可以使他们在玩中学、在学中玩，没有丝毫的压力。对于个别能力弱的孩子，我采用集体与个别辅导的形式，并在日常生活中给他们提供机会，让能力弱的孩子不会为此而产生畏惧的心理；对于幼儿的新观点新发现，我总是鼓励和尊重幼儿的观点，并共同分享。如：有的幼儿认为罐宝宝吃饱了可以喝水，我肯定了幼儿的想法，并引导幼儿听一听罐宝宝肚里的水声，拓展了幼儿的视野与经验。
幼儿园中班科学活动说课稿：小树叶找妈妈
一、说教材我今天说课的内容是中班科学课《小树叶找妈妈》。.教材分析：新《纲要》中科学领域提出了：对周围事物和现象感兴趣，有好奇心和求知欲：能运用各种感官，动手动脑，探究问题的目标。《小树叶找妈妈》这一活动是在平时到户外散步的时候，小朋友对树叶产生了浓厚的兴趣，所以结合本季节开展的主题：金色的秋天，我设计了一系列关于树叶的活动，本次活动就是其中之一。“从幼儿身边最熟悉的事物出发”是瑞吉欧教育理念之一，在开展活动的过程中，我们细致地观察、倾听幼儿的言行，及时捕捉他们的兴趣点，以及他们的日常生活为基础，贴近幼儿自身的经验进行自然而然的引发，层层深入开展活动。我们鼓励他们以自己喜欢的方式来表现，从不同角度出发，通过各种手段来发现问题。在摆摆说说的活动中，他们的想象力发展了，会用自己的话语描述对家的认识。二、说目标活动目标是教学活动的起点和归宿，对活动起着导向作用。根据中班幼儿年龄特点及实际情况，我确立了情感、认知、能力方面的目标，其中既有独立表达的成分，又有相互融合的一面。本次活动目标为：1、引导幼儿观察、对应、和比较，认识树叶的不同。发展幼儿的比较能力、思维能力，激发幼儿的探索的兴趣。2、教师对幼儿进行保护树木教育，知道树木对人类的重要性。3、激发对周围事物的关心，能清楚表达自己的意思，发展幼儿的口语表达能力。4、培养幼儿的社会交往能力，让幼儿获得帮助他人的情感体验。难点：观察、对应、和比较，认识树叶的不同。在活动中我先让幼儿观察树叶的颜色、大小、形状等特征，然后引导幼儿运用观察、比较、对应的方法帮小树叶找妈妈，最后通过送小树叶回家，巩固对树叶特征及名称的认识。
感恩环境，学会爱护-从身边的小事做起说课稿
辅导员小结：通过看视频、环保知识问答、谈感受、动手做等系列活动，我们了解了许多环保知识，同时也明白了保护环境的重要性。并再次提醒我们保护环境，可以从身边的小事做起，是我们每个人都可以做到的，也不要让这句话成为空话。五、活动反思：上完本次队会课，我感触较深。首先，通过这次主题队会，我学会了彻底放手让队员去主持队会，要相信自己队员，敢于放手锻炼队干部。其次，要注意细节教育，中队会结束后，大队辅导员就指出了个别队员的红领巾佩戴不够端正，队礼不够标准。想想平时我也注意到了，但只是偶尔提醒一下，没有引起重视，这在我以后的队会活动中一定会加强的。最令我欣慰的是，这次主题队会让队员们都感受到了环境对我们的重要性，感受到环境受到污染，对我们的生活所造成的影响。尽管本次队会已经结束了，但是相信孩子们都会怀着一颗感恩的心将感恩的火种传递下去，从自己做起，从小事做起，保护我们赖以生存的自然环境。

新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教学设计
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
新人教版高中英语必修3Unit 1 Festivals and Celebrations-Reading for Writing教学设计一

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.

新人教版高中英语必修3Unit 2 Morals and Virtues-Listening &Speaking＆Talking教学设计
Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.
