1． How is Hunan cuisine somewhat different from Sichuan cuisine?The heat in Sichuan cuisine comes from chilies and Sichuan peppercorns. Human cuisine is often hotter and the heat comes from just chilies.2.What are the reasons why Hunan people like spicy food?Because they are a bold people. But many Chinese people think that hot food helps them overcome the effects of rainy or wet weather.3.Why do so many people love steamed fish head covered with chilies?People love it because the meat is quite tender and there are very few small bones.4.Why does Tingting recommend bridge tofu instead of dry pot duck with golden buns?Because bridge tofu has a lighter taste.5 .Why is red braised pork the most famous dish?Because Chairman Mao was from Hunan, and this was his favorite food.Step 5: Instruct students to make a short presentation to the class about your choice.

The theme of this section is to express people's views on studying abroad. With the continuous development of Chinese economic construction, especially the general improvement of people's living standards, the number of Chinese students studying abroad at their own expense is on the rise. Many students and parents turn their attention to the world and regard studying abroad as an effective way to improve their quality, broaden their horizons and master the world's advanced scientific knowledge, which is very important for the fever of going abroad. Studying abroad is also an important decision made by a family for their children. Therefore, it is of great social significance to discuss this issue. The theme of this section is the column discussion in the newspaper: the advantages and disadvantages of studying abroad. The discourse is about two parents' contribution letters on this issue. They respectively express their own positions. One thinks that the disadvantages outweigh the advantages, and the other thinks that the advantages outweigh the disadvantages. The two parents' arguments are well founded and logical. It is worth noting that the two authors do not express their views on studying abroad from an individual point of view, but from a national or even global point of view. These two articles have the characteristics of both letters and argumentative essays1.Guide the students to read these two articles, and understand the author's point of view and argument ideas2.Help the students to summarize the structure and writing methods of argumentative writing, and guides students to correctly understand the advantages and disadvantages of studying abroad3.Cultivate students' ability to analyze problems objectively, comprehensively and deeply

好玩的磁铁教案教学设计
中班的幼儿开始愿意探究新异的事物或现象来满足自己的好奇心，所以，我们的科学活动设计要在浅显易懂，适合中班幼儿年龄特征的同时，引发幼儿对科学的初步探究能力。中班的幼儿已经具有注意到新异事物或现象的，因此，我们在设计科学活动时要让幼儿充分发挥想象，对磁铁这种“新异”事物提出问题，如什么是磁铁？什么时候看见过磁铁？等等类似的问题，可以增强幼儿的探索兴趣，提高幼儿的探索的积极性，有利于激发幼儿的想象力。 中班幼儿主要以具体形象为主，需要具体的活动场景和活动形式，所以活动设计要提供幼儿合适的情景以提供操作思考的机会，进一步发展幼儿的自主性和主动性。中班幼儿与小班幼儿相比，活动时间也有所增加，因此也需要在活动时间上给予一定的保证。
图形的全等教案教学设计
教法分析：在新课程的教学中教师要向学生提供从事数学活动的机会,倡导让学生亲身经历数学知识的形成与应用过程，鼓励学生自主探索与合作交流，让学生在实践中体验、学习。因此，本节课我采用了多媒体辅助教学与学生动手操作、观察、讨论的方式，一方面能够直观、生动地反映各种图形的特征，增加课堂的容量，吸引学生注意力，激发学生的学习兴趣；另一方面也有利于突出重点、突破难点，更好地提高课堂效率。学法分析：初二年级学习对新事物比较敏感，通过新课程教学的实施，学生已具有一定探索学习与合作交流的习惯。但是一下子要学生从直观的图形去概括出抽象图形全等的概念这是比较困难的。因此，我指导学生：一要善于观察发现；二要勇于探索、动手实验；三要把自己的所思所想大胆地进行交流，从而得出正确的结论，并掌握知识。
频率的稳定性教案教学设计
活动内容：教师首先让学生回顾学过的三类事件，接着让学生抛掷一枚均匀的硬币，硬币落下后，会出现正面朝上、正面朝下两种情况，你认为正面朝上和正面朝下的可能性相同吗？（让学生体验数学来源于生活）。活动目的：使学生回顾学过的三类事件，并由掷硬币游戏培养学生猜测游戏结果的能力，并从中初步体会猜测事件可能性。让学生体会猜测结果，这是很重要的一步，我们所学到的很多知识，都是先猜测，再经过多次的试验得出来的。而且由此引出猜测是需通过大量的实验来验证。这就是我们本节课要来研究的问题（自然引出课题）。
角平分线的性质教案教学设计
这是本节课的重点。让同学们将∠aob对折，再折出一个直角三角形（使第一条折痕为斜边），然后展开，请同学们观察并思考：后折叠的二条折痕的交点在什么地方？这两条折痕与角的两边有什么位置关系？这两条折痕在数量上有什么关系？这时有的同学会说：“角的平分线上的点到角的两边的距离相等”.即得到了角平分线的性质定理的猜想。接着我会让同学们理论证明，并转化为符号语言，注意分清题设和结论。有的同学会用全等三角形的判定定理aas证明，从而证明了猜想得到了角平分线的性质定理。
北师大版初中七年级数学下册等可能事件的概率说课稿
经过探究发现只有10与11出现的概率最大且相等（在探究的过程中提醒学生按求等可能性事件的概率步骤来做，在判断是否等可能和求某个事件的基本数上多启发和引导，帮助学生顺利突破难点。）及时表扬答对的学生，因为这个问题整整过了三个世纪，才被意大利著名的天文学家伽利略解决。后来法国数学家拉普拉斯在他的著作《分析概率论》中，把伽利略的这个解答作为概率的一个基本原理来引用。（适当的渗透一些数学史，学生对学习的兴趣更浓厚，可以激发学生课后去进一步的探究前辈们是如何从不考虑顺序到想到考虑顺序的）8、课堂小结：通过这节课的学习，同学们回想一下有什么收获？1、基本事件和等可能性事件的定义。2、等可能性事件的特征：（1）、一次试验中有可能出现的结果是有限的。（2）、每一结果出现的可能性相等。3、求等可能性事件概率的步骤：（1）审清题意，判断本试验是否为等可能性事件。
【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．

有理数复习教案教学设计
3）乘除运算①有理数的乘法法则：（老师给出，学生一起朗读）1. 两数相乘，同号得正，异号得负，并把绝对值相乘；2. 任何数与零相乘都得零；3. 几个不等于零的数相乘，积的符号由负因数的个数决定，当负因数有奇数个数，积为负；当负因数的个数为偶数个时，积为正；4. 几个有理数相乘，若其中有一个为零，积就为零。②有理数的除法法则：（老师提问，学生回答）1. 两个有理数相除，同号得正，异号得负，并把绝对值相除；2. 除以一个数等于乘以这个数的倒数。③关系（老师给出）除法转化为乘法进行运算。
反比例函数教案教学设计
本节的内容主要是反比例函数的概念教学.反比例函数概念的建立，不能从形式上进行简单的抽象与概括，而是对这些实例从不同角度抽象出本质属性后，再进行概括。教材设计的基本思路是从现实生活中大量的反比例关系中抽象出反比例函数概念，让学生进一步感受函数是反映现实世界中变量关系的一种有效数学模型，逐步从对具体反比例函数的感性认识上升到对抽象的反比例函数概念的理性认识. 同时本节的学习内容，直接关系到本章后续内容的学习，也是继续学习其它各类函数的基础，其中蕴涵的类比、归纳、对应和函数的数学思想方法，对学生今后研究问题、解决问题以及终身的发展都是非常有益的.基于以上分析，本节教学设计是建立在一个个数学活动的基础上，经过对情境理解、本质抽象的积累而形成的.让学生对一类问题情境中两个变量间的关系，在充分经历写表达式，计算函数值和观察函数值随自变量变化规律的过程中，逐步概括形成反比例函数的概念.针对教学实际，我选取了贴学生现实的，有价值的实例“文具店里买学习用品”和“剪面积为定值的长方形纸片”等作为问题情境.
【高教版】中职数学基础模块上册：3.3《函数的实际应用举例》教学设计
课程分析中专数学课程教学是专业建设与专业课程体系改革的一部分，应与专业课教学融为一体，立足于为专业课服务，解决实际生活中常见问题，结合中专学生的实际，强调数学的应用性，以满足学生在今后的工作岗位上的实际应用为主，这也体现了新课标中突出应用性的理念。分段函数的实际应用在本课程中的地位：（1） 函数是中专数学学习的重点和难点，函数的思想贯穿于整个中专数学之中，分段函数在科技和生活的各个领域有着十分广泛的应用。（2） 本节所探讨学习分段函数在生活生产中的实际问题上应用，培养学生分析与解决问题的能力，养成正确的数学化理性思维的同时，形成一种意识，即数学“源于生活、寓于生活、用于生活”。教材分析 教材使用的是中等职业教育课程改革国家规划教材，依照13级教学计划，函数的实际应用举例内容安排在第三章函数的最后一部分讲解。本节内容是在学生熟知函数的概念，表示方法和对函数性质有一定了解的基础上研究分段函数，同时深化学生对函数概念的理解和认识，也为接下来学习指数函数和对数函数作了良好铺垫。根据13级学生实际情况，由生活生产中的实际问题入手，求得分段函数此部分知识以学生生活常识为背景，可以引导学生分析得出。
