人教版高中地理必修1第五章第二节自然地理环境的差异性教案
【补充说明】我们这节课简要地分析了陆地环境的三种地域分异规律。实际上，世界上的任何事物有其一般性，也有它的特 殊性。在地带性分异规律的基础上，陆地环境因为受到海陆分布、地形 起伏等因素的影响，也会出现一些不规律的现象，这种现象称为非地带性。例如，我们在初中地理中学过绿洲。还记得什么叫绿洲吗？再比如，在南美洲的西海岸（太平洋沿岸），有一条狭长的（热带）荒漠带，而缺少热带草原带，热带雨林带主要是分布在赤道以北地区。这主要是受大的地形起伏的影响。因为南美洲西部是一列高大的安第斯山脉，受其影响，两边的气候状况不同，所以就出现了分布规律不同的自然带，这也是一种非地带性现象。【总结】有规律分布的自然带构成了全球和谐的自然环境整体。自然带之间错综复杂的、微妙的要素关系，有许多是人类还没有认识到的。因此，人类不能随意去破坏任何哪怕是极微小的环节，也许它 带来的影响会是全球性的。保护全球环境，人人有责。

人教版高中地理必修3第二章第一节荒漠化的防治教案
1．根据下面的图文资料，说明前苏联垦荒区土壤风蚀的潜在自然背景。并说明人们的生产活动怎样加剧了这个过程。点拨：对图2.16的分析,要知道”垦荒地区”处于亚欧大 陆的中部偏北的地方,虽处于西风带但远离水汽来源,故降水稀少。从其周边的内陆湖“里海”、“咸海”的分布特点，可以推断，这是一个半荒漠向干草原的过渡地带，是一个生态环境比较脆弱的地区，其自然地理状况必定是寒冷、干旱、大风。2．20世纪60年代中期以来，前苏联在总结大规模垦荒经验教训的基础上，采取了一系列综合防护措施。仔细分析这些措施，你认为该地区防治荒漠化(土壤风蚀)的主要方向是什么?点拨：要善于将所列四项保护措施逐条进行分析，而后进行归纳，不难找出它们之间的共同的东西，那就是“抗旱、防风、保水、保土、保肥”。3．根据所学知识，你认为前苏联垦荒区防治荒漠化的对策与措施可以被我国的哪些地区所借鉴。
人教版高中地理选修3第二章第三节我国的旅游资源教案
2．对世界遗产的开发与保护原则——保护第一我国的世界文化遗产、世界文化与自然双遗产具有时代性、不可再生性和不可替代性，我国的世界自然遗产都代表着某一类地质地貌中最重要的历史演化过程，展示了我国独特的地质地貌和生物资源。世界遗产的开发与保护之间存在一定的矛盾。我们必须坚持保护第一的原则。旅游开发只是世界遗产的功用之一，必须十分慎重，做到保护与开发协调统一，不能造成对世界遗产的任何破坏。案例②我国第一个世界文化与自然双遗产——泰山通过学习案例②，了解到：①泰山不仅具有科学价值较高的地质构造，还具有多样的地貌景观，罕见的天象景观，丰富的生物资源。泰山自古以来即被誉为名山，受到皇家和百姓的顶礼膜拜，各朝各代几乎都进行过封禅行为，从而留下了深厚的历史文化遗存，这一点跟其他名山相比是独一无二的。
人教版高中地理选修3第四章第二节旅游开发中的环境保护教案
1、说说旅游环境容量测算对颐和园环境保护所起的作用。点拨：旅游环境容量测算对颐和园环境保护所起的作用是通过对游客流量的控制来实现的。颐和园的旅游吸引物有许多是珍贵的文物，游客的触摸、践踏等都会使文物遭受损耗控制客流量就控制了这些损耗。游客过多，废弃物也过多，超过颐和园的承受能力就会造成污染，控制客流量可以使废弃物控制在处理能力范围内。控制游客容量，可避免游客过多造成旅游氛围和景观的破坏，可避免发生各种矛盾和不文明行为乃至犯罪行为。旅游环境容量测算为颐和园的管理、发展和规划提供了基本依据，有助于管理部门因时因地做好管理、监督、疏导工作，有助于制订颐和园旅游发展规划，还有助于采取颐和园客流的时空分流措施。2、你还有没有更好的办法来解决颐和园旅游环境容量问题。点拨：解决颐和园旅游环境容量问题可以从“开源”和“节流”两方面加以考虑。
人教版高中地理选修3第一章第二节旅游资源的类型教案
根据旅游资源的本质属性，通常将旅游资源划分为自然旅游资源和人文旅游资源两大类。（——此时将上述景观划分到这两类中去）我们凭直觉应该知道哪些是自然，哪些是人文旅游资源。那么两种资源是怎样定义与划分的呢？一、自然旅游资源与人文旅游资源P11与P12，两类资源。解释：一般而言，自然旅游资源以地貌景观为核心，人文旅游资源以建筑景观为核心。前者主要与各地的自然条件相关，后者主要与人类历史相关。但：有时，两类资源之间难以断定其归属，因为自然旅游资源的开发必须要经过人为的加工，不可能没有人文附加成分。而人类社会多数的创造，即使是最能体现人文色彩的民族风情，都与自然条件有密不可分的关系。两类资源又可细分为若干类，P11与P13阅读材料。
人教版高中历史必修2二战后苏联的经济改革教案
⑤强调对外关系的灵活性。戈尔巴乔夫指出在对外政策中要采取多种办法选择不同的策略路线达到既定目标。在外交谈判中不要为自己制造死胡同，也不要给对方制造死胡同，要善于迎合伙伴，寻求接触点。在这种思想指导下，苏共采取的对外战略是以军控为中心的缓和战略，具体政策是继续与美国就裁军、消减核武器、限制地区冲突等问题进行谈判，缓解苏美关系；对西欧争取建立“全欧大厦”；对东欧实行纠偏、不干涉政策；对中国改善关系，实现关系正常化；调整与第三世界国家关系，解决阿富汗、柬埔寨等问题。 3、影响：①经济改革措施仓促上马，缺少宏观决策和相应的配套措施；加上戈尔巴乔夫没有放弃苏联的传统做法，继续优先发展重工业，致使改革未达到预期的效果，苏联经济持续下滑②经济体制改革受挫后，把改革的重点转向政治领域，最终导致国内局势的失控和苏联的解体。

（一）例题引入篮球联赛中，每场比赛都要分出胜负，每队胜1场得2分，负1场得1分。某队在10场比赛中得到16分，那么这个队胜负场数分别是多少？方法一：（利用之前的知识，学生自己列出并求解）解：设剩X场，则负（10－X)场。方程：2X+(10－X)=16方法二：（老师带领学生一起列出方程组）解：设胜X场，负Y场。根据：胜的场数+负的场数=总场数 胜场积分+负场积分=总积分得到：X+Y=10 2X+Y=16
人教版高中数学选择性必修二变化率问题教学设计
导语在必修第一册中，我们研究了函数的单调性，并利用函数单调性等知识，定性的研究了一次函数、指数函数、对数函数增长速度的差异，知道“对数增长” 是越来越慢的，“指数爆炸” 比“直线上升” 快得多，进一步的能否精确定量的刻画变化速度的快慢呢，下面我们就来研究这个问题。新知探究问题1 高台跳水运动员的速度高台跳水运动中，运动员在运动过程中的重心相对于水面的高度h(单位：m)与起跳后的时间t(单位：s)存在函数关系h(t)＝－4.9t2＋4.8t＋11.如何描述用运动员从起跳到入水的过程中运动的快慢程度呢？直觉告诉我们，运动员从起跳到入水的过程中，在上升阶段运动的越来越慢，在下降阶段运动的越来越快，我们可以把整个运动时间段分成许多小段，用运动员在每段时间内的平均速度v ?近似的描述它的运动状态。
高二学生国旗下讲话稿：天下兴亡，我的责任
敬爱的老师们，亲爱的同学们：大家早上好！我先给大家讲一个故事：1920年，有一位11岁的美国男孩在踢足球时不小心踢碎了邻居家的玻璃，邻居愤怒不已，向他索赔12.5美元。这12.5美元在当时可谓是天文数字，足够买下125只生蛋的母鸡了。男孩把闯祸的事情告诉父亲，并且忏悔。见儿子为难的样子，父亲拿出了12.5美元说：“这笔钱是我借给你的，一年后你要分毫不差地还给我。”从此，这个男孩每逢周末、假日，便外出辛勤打工。经过半年的努力，他终于挣足了12.5美元，分毫不差地还给了父亲。这个男孩就是后来的美国总统里根。他在回忆这件事时说：“通过自己的劳动来承担过失，使我懂得了什么叫责任。”责任，这两个字很好读，一点也不拗口，但这是个沉甸甸的话题。责任是什么？用歌德的话来讲，就是对自己要求去做的事情有一种爱。这是一个真实的故事。有一个人来他公司应聘，经过交谈，他觉得那个人不适合他们公司的工作。因此，他很客气地和那个人道别。那个人从椅子上站起来时，手指不小心被椅子跳出来的钉子划了一下。那人顺手拿起老板桌子上的镇纸，把跳出来的钉子砸了进去，然后和老板再见。
初二学生国旗下讲话稿——我心中的木棉花
在我们附中的东南角，有一棵高大的木棉树。木棉，是我们广州市的市花，是花园酒店、中国南方航空公司和广州电视台使用的标志，也是XX年第一届亚洲残疾人运动会的吉祥物。每年四月，当北方才刚刚有绿色的影子的时候，火红的木棉已经灿烂耀眼，它火红火红，一朵一朵像绽放的笑脸，像一片一片熊熊的火焰燃烧在枝头，它象征和平、幸福、友谊、安康。（它的花语告诉我们----珍惜身边的人，珍惜眼前的幸福！）可是最近，由于木棉花的花期短、覆盖率少，民间发出是否可以评选“第二市花”的建议，这也使我再次关注我们广州的“英雄花”——木棉。记得小时候，在珠江沿岸，每年燕子唱歌的时候，滨江路的木棉花总是开得最旺盛。吃过晚饭下楼散步，总能捡到一、二十朵掉落的木棉；有时在树下跑过，总能听见那木棉落在地上的声音。每每捡到木棉花，我总是把它们揣在衣服里，到了家，母亲就把较好的收集起来，夏天熬粥。我，就是吃着那又涩又甜的木棉花粥长大的。作为一个土生土长的广州仔，木棉花，就像是我的朋友。
国旗下的讲话：铭记一二·九（学生演讲稿）
国旗下的讲话：铭记一二·九 各位老师、同学们：早上好！今天是一二。九运动的纪念日，这个青年学生的爱国运动距今已有73周年了。今天，站在鲜艳的国旗下，让我们一同回顾历史：谁都应该记得1935年的12月9日，谁都不应该忘记“一二。九”这场轰轰烈烈的学生爱国救亡运动。虽然，它早已成为历史，但它的事迹，它的精神，却早已铭刻进了我们每一位炎黄子孙的心中。他们用自己的青春和热血掀起了全国抗日救亡运动新的高潮。今天，我们在这里缅怀一二。九先辈的功绩，心潮澎湃，不能自己。作为新时代的青少年，同学们，我们又应该做些什么？抗战时期的大中学学生，他们把自己的生命和国家的命运、民族的兴亡，紧紧的联系在了一起。而我们，是否也应该象他们一样呢？答案当然是肯定的，但现实又如何呢？台下的有一部分同学，当你在课堂上无精打采的听课时，当你将青春耗费在虚拟的网络时空时，当你沉溺于追逐流行和崇拜明星时，当你盲目的“耍酷”“装帅”，张扬你所谓的“个性”时，不知你是否想到了作为当代青少年那肩头沉重的使命感？
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.
新人教版高中英语必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教学设计二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.
