人教部编版语文八年级上册三峡教案
此外，多种形式的朗读，为学生在朗读中理解字词、内容、情感打下了基础。素养提升《三峡》中的修辞手法1.并提为了使句子紧凑、文笔简练，古人常用并提法行文，把本来应该写成两个短语或两个句子的话，合并为形式上的一个短语或一个句子，把相同的语句成分放在一起并提，但表意上仍然必须按照两个短语或句子的组合关系来分别相承，这种修辞手法就叫并提。这种句子翻译时应分为两句。如：（1）“自非亭午夜分，不见曦月。”“亭午”“夜分”是两个不并存的时间，“曦”和“月”是两种不同的自然现象，合起来是讲不通的，这句话应理解为“自非亭午，不见曦；自非夜分，不见月”（如果不是在正午，就看不到太阳；如果不是在半夜，就看不到月亮）。（2）“素湍绿潭，回清倒影。”这句和上句一样，应理解为“素湍回清，绿潭倒影”（白色的急流中有回旋的清波，绿色的潭水中有倒映着的各种景物的影子）。
人教部编版语文八年级上册诗词五首教案
设问2：下片主要写了什么内容？预设 回答天帝。下片紧承上片的天帝询问，作出回答。我报路长嗟日暮，学诗谩有惊人句。（这是词人回告天帝。一个“嗟”字，生动地传达出作者对日暮途远的叹息，感慨空有才华，于世事无补。）九万里风鹏正举。风休住，蓬舟吹取三山去！（回答天帝，希望自己像大鹏一样高飞远走，到海上仙山去。传达出词人对现实的厌弃和对美好境界的追求。）设问3：本词和《赤壁》都表现了作者对自身才华、命运的认识，但又有什么不同？预设 杜牧借对三国史事的遐想，慨叹历史上英雄成名的际遇，曲折表达自己空有抱负，生不逢时、无从施展的无奈；本词是借梦境与天帝对话，表达对自己空有一身文学才华却屡遭战乱，甚至连个人的安定幸福都无法保障的不满。【设计意图】本环节旨在品读《渔家傲》，引导学生通过品读词句，感知词作内容，理解词人情感，并通过鉴赏艺术手法，提高审美能力。
人教部编版语文八年级上册苏州园林教案
1.南方园林江南有温和的气候、充沛的水量、丰盛的物产、优美的景色、宽松的人文环境，其园林营建必然自呈特色。《中国大百科全书·江南园林》将其总结为三点：第一，叠石理水、水石相映。太湖石奇特多姿，在庭中造型尤佳。最称绝的是苏州瑞云峰、杭州植物园绉云峰、上海豫园玉玲珑。第二，花木种类多。第三，建筑风格淡雅、朴素。布局自由，结构不拘定式，清新洒脱，小巧细腻，幽雅美丽。小阁临流，冷色多，像山水画。青瓦素墙，褐色门窗，官僚政治意识淡薄，书卷气深浓。南方园林以江南园林为代表。江南园林主要指以苏州、杭州、无锡、扬州、南京、上海、常熟等城市为主的私家园林。江南园林属于文人写意派山水园，文人画家参与造园，以人工造景为主，规划巧妙，设计精致，人文气氛浓。造园师在有限的空间再现真实的自然山水，以小见大，意蕴无穷。
人教部编版语文八年级上册唐诗五首教案
（生交流讨论以下问题，师小结）设问1：本诗是围绕哪两个字来写的？诗人的行踪是怎样的？预设 围绕“春”“行”来写的。诗人行踪：孤山寺北—贾亭西—湖东—白沙堤。设问2：颔联中的“几处”“谁家”能不能换成“处处”“家家”，为什么？预设 不能。因为早莺尚少，只有“几处”；新燕不多，不知“谁家”。“几处”和“谁家”突出了初春事物都还很稀少。如果换成“处处”和“家家”，就体现不出早春的特点了。设问3：颔联中的“争”和“啄”两个动词用得好，请说说好在哪里。预设 这两个动词惟妙惟肖地描摹了莺燕的动态，传神地描绘了一幅充满生机的早春图，流露出诗人对如此美景的无限喜爱之情。设问4：尾联抒发了作者什么样的感情？预设 “最爱湖东行不足”，说明诗人流连忘返，陶醉在美好的湖光山色中了。体现了作者对早春西湖美景的喜爱和赞美之情。
人教部编版语文八年级上册愚公移山教案
阴阳原是指日光的向背，向日为阳，背日为阴。我国古代地名中的“阴”和“阳”实际上是一种方位指示，“日之所照曰阳”，也就是说太阳所能照到的地方就称为阳。 山水阴阳是说古代以山南、水北为阳，以山北、水南为阴。 形成这种局面的原因是山峰高耸，日光能照射到的地方是山的南面；而河流位于地平面以下，所以太阳能照射到的地方其实是河流的北面。 故有“山南水北谓之阳，山北水南谓之阴”的说法。在我国历史上，很多地名及地理表述都与此关系密切，如江阴、衡阳、汉阳等。 《愚公移山》 中说：“指通豫南，达于汉阴。” 其中的“汉阴”是指汉水的南岸。 “泰山之阳，汶水西流；其阴，济水东流”（姚鼐《登泰山记》）、“所谓华山洞（南宋王象之《舆地纪胜》写为‘华阳洞’。 看正文下句，应为‘华阳洞’）者，以其乃华山之阳名之也”
人教部编版语文八年级上册中国石拱桥教案
中国的拱桥的历史可追溯到东汉时期，至今已有一千八百多年。中国的拱桥别具一格，造型优美，曲线圆润，形式多样，世界罕见。拱桥按照建筑材料分为石拱桥、砖拱桥和木拱桥，其中较为常见的是石拱桥。拱桥又分为单拱、双拱、多拱，拱的多少根据河面的宽度而定。多拱桥一般正中间的拱较大，两边的拱略小。根据拱的形状，又分五边、半圆、尖拱、坦拱。桥面上铺板，桥边有栏杆。单孔拱桥的拱形呈抛物线的形状，如北京颐和园的汉白玉石桥玉带桥。多孔拱桥适于跨度较大的宽广水面，常见的多为三、五、七孔，以奇数为多，偶数较少。当多孔拱桥某个孔的主拱受荷时，能通过桥墩的变形或拱上结构的作用把荷载由近及远地传递到其他孔主拱上去，这样的拱桥称为连续拱桥，简称“联拱”。如建于唐代元和年间的古桥苏州宝带桥，桥下共有53个孔相连，桥孔之多，结构之精巧，为中外建桥史上所罕见。
人教A版高中数学必修二总体离散程度的估计教学设计
问题二：上述问题中，甲、乙的平均数、中位数、众数相同，但二者的射击成绩存在差异，那么，如何度量这种差异呢？我们可以利用极差进行度量。根据上述数据计算得：甲的极差=10-4=6 乙的极差=9-5=4极差在一定程度上刻画了数据的离散程度。由极差发现甲的成绩波动范围比乙的大。但由于极差只使用了数据中最大、最小两个值的信息，所含的信息量很少。也就是说，极差度量出的差异误差较大。问题三：你还能想出其他刻画数据离散程度的办法吗？我们知道，如果射击的成绩很稳定，那么大多数的射击成绩离平均成绩不会太远；相反，如果射击的成绩波动幅度很大，那么大多数的射击成绩离平均成绩会比较远。因此，我们可以通过这两组射击成绩与它们的平均成绩的“平均距离”来度量成绩的波动幅度。
人教A版高中数学必修二总体取值规律的估计教学设计
可以通过下面的步骤计算一组n个数据的第p百分位数：第一步：按从小到大排列原始数据；第二步：计算i=n×p%；第三步：若i不是整数，而大于i的比邻整数位j，则第p百分位数为第j项数据；若i是整数，则第p百分位数为第i项与第i+1项的平均数。我们在初中学过的中位数，相当于是第50百分位数。在实际应用中，除了中位数外，常用的分位数还有第25百分位数，第75百分位数。这三个分位数把一组由小到大排列后的数据分成四等份，因此称为四分位数。其中第25百分位数也称为第一四分位数或下四分位数等，第75百分位数也称为第三四分位数或上四分位数等。另外，像第1百分位数，第5百分位数，第95百分位数，和第99百分位数在统计中也经常被使用。例2、根据下列样本数据，估计树人中学高一年级女生第25，50，75百分位数。

（2）平均数受数据中的极端值（2个95）影响较大，使平均数在估计总体时可靠性降低，10天的用水量有8天都在平均值以下。故用中位数来估计每天的用水量更合适。1、样本的数字特征：众数、中位数和平均数；2、用样本频率分布直方图估计样本的众数、中位数、平均数。（1）众数规定为频率分布直方图中最高矩形下端的中点；（2）中位数两边的直方图的面积相等；（3）频率分布直方图中每个小矩形的面积与小矩形底边中点的横坐标之积相加，就是样本数据的估值平均数。学生回顾本节课知识点，教师补充。 让学生掌握本节课知识点，并能够灵活运用。

【高教版】中职数学拓展模块：3.2《二项式定理》教学设计
一、定义： ，这一公式表示的定理叫做二项式定理，其中公式右边的多项式叫做的二项展开式；上述二项展开式中各项的系数 叫做二项式系数，第项叫做二项展开式的通项，用表示；叫做二项展开式的通项公式．二、二项展开式的特点与功能1. 二项展开式的特点项数：二项展开式共（二项式的指数+1）项；指数：二项展开式各项的第一字母依次降幂（其幂指数等于相应二项式系数的下标与上标的差），第二字母依次升幂（其幂指数等于二项式系数的上标），并且每一项中两个字母的系数之和均等于二项式的指数；系数：各项的二项式系数下标等于二项式指数；上标等于该项的项数减去1（或等于第二字母的幂指数；2. 二项展开式的功能注意到二项展开式的各项均含有不同的组合数，若赋予a，b不同的取值，则二项式展开式演变成一个组合恒等式．因此，揭示二项式定理的恒等式为组合恒等式的“母函数”，它是解决组合多项式问题的原始依据．又注意到在的二项展开式中，若将各项中组合数以外的因子视为这一组合数的系数，则易见展开式中各组合数的系数依次成等比数列．因此，解决组合数的系数依次成等比数列的求值或证明问题，二项式公式也是不可或缺的理论依据．

新人教版高中英语必修3Unit 1 Festivals and Celebrations-Reading and Thinking教学设计
The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2.

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教学设计二
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.

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.
