部编版语文八年级下册《综合性学习：倡导低碳生活》教案
【新课导入】抬头仰望天空，你会发现曾经湛蓝的天不再那么明净；低头俯视大地，你会发现曾经清澈见底的河流不再那么透明；静静聆听，回响在我们耳边的不再是婉转动听的鸟叫虫鸣，而是轰隆隆的机器运作；放眼望去，呈现在我们眼前的不再是郁郁葱葱的森林绿地，而是灰暗单调的高楼和冰冷的水泥路面……随着工业化的进程，我们的生活已被污染包围，倡导低碳生活，刻不容缓。【重点解读】认识低碳生活、宣传低碳生活、争做低碳达人。1. 认识低碳生活低碳，英文为low carbon，意指较低的温室气体（二氧化碳为主）排放。低碳生活，就是指生活作息时所耗用的能量要尽力减少，从而降低碳，特别是二氧化碳的排放量，进而减少对大气的污染，减缓生态恶化，要求从节水、节电、节气和回收四个环节来改变生活细节。
部编版语文八年级下册《综合性学习：举办演讲比赛》教案
【新课导入】演讲比赛是提高同学口语和表达能力的一项竞赛，不仅要求参赛者有良好的文字功底和修养，同时也要有良好的口才和表达能力，以及很强的感染力，通过自己的叙述将观众带入自己的世界，同时演讲比赛也是一个人综合素质的体现，要想更多的人认识自己，了解自己，首先就得学会说话，学会推销自己，通过自己的介绍让同学了解自己，喜欢自己，好的演讲口才终身受用。【重点解读】充分的赛前准备是比赛成功的基础。建议大家：（1）举办小组选拔赛。选择同一题目撰写演讲稿的同学自由组成小组，先在小组内进行选拔比赛，每组选出一到两名同学参加班级演讲。小组选拔时，一方面要重视演讲的内容，同时要考虑现场的声音、语气、表情、动作等，通过综合评价，推举优秀代表。
人教版高中语文必修2《想象世界学习虚构》教案2篇
虚构不等于说假话。它是一种源于生活，但高于生活的艺术真实。我们可以举个例子：我国公认的最权威最真实的史书是——《史记》，那么，大家认为《史记》里有没有虚构呢？有。必修一的《鸿门宴》里就有虚构。大家想：司马迁是哪个朝代的人？西汉汉武帝时。刘邦项羽是哪个朝代的？秦末时期。那司马迁不可能坐时光穿梭机到秦末去参加鸿门宴吧？既然他没不在场，那课文《鸿门宴》里人物的语言、动作、甚至是表情从何而来呢？对，是司马迁根据有限的史料加以补充，想象、虚构出来的。那么，同学们在写作文时，也可以不必拘泥于亲身经历的事情，毕竟生活是平淡的，毕竟大家的生活阅历也有限，有时候，我们发挥想象、虚构一个故事来反映生活的真实，也许更生动、也更典型。所以，近年来高考试卷中都提示考生：作文可以大胆想象，编写故事。按照编故事的方式不同，我们的虚构性作文又可以写哪些类型呢：小说，散文，童话，寓言，科幻，故事新编……
人教版高中语文必修2《直面挫折学习描写》教案2篇
《贫寒是福天道酬勤石智勇从挫折中奋起》也许是自幼的贫寒生活塑造了石智勇内向的性格，即使是胸挂金灿灿的奖牌接受全场观众欢呼，他的表情也是略显羞涩的。小时候吃不饱肚皮的经历让他至今在“最喜欢的东西”一栏还填写着“食物”二字，而“穷人的孩子早当家”的坚韧，却又是促成他今日辉煌的动力。中国举重队副总教练陈文斌赛后说道：“智勇这几年练得很苦，今天终于有了这样的成绩，这是天道酬勤的结果。石智勇的奥运会金牌是中国男举的一次突破，我们非常激动。”在希腊神话里，命运女神总是让英雄历经磨难。石智勇也不例外。四年前的悉尼奥运会前夕，他在一次训练中扭伤脚踝，失去了参赛机会。“当时我伤心极了，不敢看电视直播，我怕参赛的选手成绩太低了。高点我还好一点，自欺欺人一下说，哎呀好高，自己去了也拿不了冠军，要是低了，自己没去，失去冠军机会，心里痛啊。后来结果出来，也不怎么高，心里真难受。”
人教版高中语文必修3《善待生命 学习论证》教案2篇
论证方法之引证法如何用好引证法：1.所引用的名言警句等针对性要强。每句名言都产生于特定的背景，都应用于特定的交际目的，即使谈同一个问题，也有不少名言可供选取。2.要简洁，不宜过多。议论是在发表自己的见解而不是在介绍他人的见解。引用他人的话，目的是为了让读者更加信服自己的话。3.要注意直接引用和间接引用的区别。直接引用务求文字、甚至标点均准确无误；间接引用只须述其大意，但要注意人称的转换。论证方法之喻证法喻证法是用设喻来论证论点的方法。在议论文中，设喻可以使论点更易懂、更风趣、更容易获得读者的认同。喻证法能化抽象为具体、化艰深为浅显、化枯燥为生动。论证方法之喻证法如何用好喻证法：1.以小见大，就近取譬。要精选生活中细小的、人们熟悉的事物做为设喻的喻体。2.喻体不求形似，只求神似。做为喻证的喻体与做为比喻的喻体不同。比喻的喻体是为了强调特征，描绘事物，侧重形似，以形比形；而喻证的喻体是为了阐发观点，以正视听，力求神似，以义取形。

人教版高中政治必修4综合探究：走进哲学，问辩人生教案
1．根据课程标准的要求。本单元的主题是“生活智慧与时代精神”，课程标准的要求主要是引导学生“思考日常生活富有哲理的事例，感悟哲学是世界观的学问，能够开启人的智慧”，“解释哲学的基本问题”，“分析实例，说明真正的哲学是时代精神的精华，明确马克思主义哲学在人类认识史上的重要地位”。这些问题，综合起来就是使学生明确哲学与我们生活的关系，认识学习哲学特别是马克思主义哲学对我们人生的作用。因此，探究本问题有助于学生更好地理解本单元的内容，完成本单元的教学目标。2．根据学生的实际需要。学习哲学特别是马克思主义哲学，可以帮助学生树立正确的世界观、人生观和价值观，这也是学习哲学的主要目的。但在学生中还不同程度地存在着“哲学与我们的生活很远”、“哲学与我无关”、“哲学对我将来从事自然科学的研究没有什么用处”等认识，这些都影响着学生对哲学学习的态度和哲学作用的发挥。设置本探究问题，有助于帮助学生澄清这些模糊认识。

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.

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

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.

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.
