空间向量基本定理教学设计人教A版高中数学选择性必修第一册
反思感悟用基底表示空间向量的解题策略1.空间中,任一向量都可以用一个基底表示,且只要基底确定,则表示形式是唯一的.2.用基底表示空间向量时,一般要结合图形,运用向量加法、减法的平行四边形法则、三角形法则,以及数乘向量的运算法则,逐步向基向量过渡,直至全部用基向量表示.3.在空间几何体中选择基底时,通常选取公共起点最集中的向量或关系最明确的向量作为基底,例如,在正方体、长方体、平行六面体、四面体中,一般选用从同一顶点出发的三条棱所对应的向量作为基底.例2.在棱长为2的正方体ABCD-A1B1C1D1中,E,F分别是DD1,BD的中点,点G在棱CD上,且CG=1/3 CD(1)证明:EF⊥B1C;(2)求EF与C1G所成角的余弦值.思路分析选择一个空间基底,将(EF) ?,(B_1 C) ?,(C_1 G) ?用基向量表示.(1)证明(EF) ?·(B_1 C) ?=0即可;(2)求(EF) ?与(C_1 G) ?夹角的余弦值即可.(1)证明:设(DA) ?=i,(DC) ?=j,(DD_1 ) ?=k,则{i,j,k}构成空间的一个正交基底.

（1）巨额的赔款，是列强对中国空前的大规模勒索；为支付这笔巨额赔款，清政府加紧搜刮人民，使人民生活更加贫困，社会经济更加凋敝。（2）在北京设立的“使馆界”，实际上是“国中之国”，是帝国主义策划侵略中国的大本营。外国侵略者控制京津地区，使清政府完全处于外国军队的控制之下，便于侵略者直接派兵镇压中国人民的反帝斗争。（3）按照条约规定，清朝官吏严厉镇压中国人民的反帝斗争，进一步成为帝国主义的帮凶。（4）改设外务部的规定，便于清政府能够按照外国侵略者的意旨实行卖国的外交政策。《辛丑条约》是帝国主义强加给中国的一个严重的不平等条约，列强除了穷凶极恶地对中国敲诈勒索外，还重新确立了以慈禧太后为首的清政府继续充当它们在华的代理人。

人教版高中历史必修3文艺复兴和宗教改革教案
三、宗教改革：1、背景：（1）文艺复兴的影响。文艺复兴中，人文主义学者尽管对宗教保持较为温和的态度，但其以人为中心的思想极大地冲击了天主教的精神独裁，天主教的权威日益受到人们的怀疑。（2）天主教会对欧洲尤其是德意志的压榨。中世纪的天主教会对人民进行严密的精神统治，基督教信仰的核心是“原罪”和“灵魂救赎”，即人生下来就有罪，只有信仰上帝，跟随耶稣才能得救。就“灵魂救赎”而言，最初强调的是个人信仰的作用，后来，神学家们又加上了种种繁杂的宗教礼仪，而且必须得到神职人员的帮助，灵魂才能得救。在经济上，天主教会还是最大的封建主，占有大量的土地，并征收什一税，对各国人民大肆搜刮。罗马教廷每年从德意志搜刮的财富达30万古尔登（货币单位），相当于“神圣罗马帝国”皇帝每年税收额的20倍。德意志也成了被教会榨取最严重的地区，素有“教皇的乳牛”之称。

人教版高中语文必修3《杜甫诗三首 咏怀古迹》教案
“千载琵琶作胡语，分明怨恨曲中论。”“怨恨”两字点明全篇主旨。千百年来，琵琶所演奏的总是从匈奴传来的撩人愁思的胡乐，正是昭君在诉说着她的怨恨！这两句从侧面烘托昭君的形象，既有对她的赞扬，又有对她的同情。读到这里，我们的耳边好像又响起了那深沉、幽怨的琵琶声！5、这首诗写的是昭君的怨恨，但首联一开始并没有写她的怨恨，写的是什么？这样写的目的又是什么？明确：群山万壑赴荆门山是群山起伏，连绵不绝；水是万壑争流，奔腾不息，直赴荆门山。其中的“赴”字用了拟人的手法，把迤逦不绝的千山万壑陡然间写活了，既有飞动之势，又有变幻之姿。从侧面烘托昭君的形象。两千多年前，一个青年女子远离父母之邦，嫁到异域，并在那里度过一生，确实需要巨大的勇气和毅力，而这雄伟的山川简直就是她那坚强的性格的象征。6、佳句鉴赏（这首诗歌当中，我认为有两句诗写得非常美，我自己很喜欢，不知道有没有同道中人？）
人教版高中历史必修3从“师夷长技”到维新变法教案
4、维新思想推动下的变法运动虽然失败了。但这是中国近代真正意义上的一次思想解放潮流，为什么？展开：维新派提倡西学，兴民权，对封建专制制度和传统观念进行了冲击，促进了中国人民的觉醒，为资产阶级民主思想的传播奠定了基础，具有思想解放的启蒙作用。是一次救亡图存的爱国运动，也是一次发展资本主义的改革运动；他们提倡资产阶级新学，批判封建主义旧学，引导人们重新认识世界，他们痛感民族危机的严重，号召人们奋起救国，谋求国家的独立富强；给古老的中国社会注入的活力是不可低估的，站在历史长河的高度看，由传统农耕社会向近代工业社会转变是一股不可抗拒的历史潮流，尽管它在19世纪末的中国遭到了暂时挫折，但对清朝的封建专制统治却是一次巨大的强烈的冲击波，它留下的痕迹是永不磨灭的，是永远鼓舞与启迪后人的。
人教版高中政治必修1积极参与国际经济竞争与合作教案
学生活动：认真阅读，积极思考。教师总结：这样一个人口大国，依靠外国是不能解决温饱问题的，更谈不上社会主义现代化。实行对外开放，发展对外经济关系，必须坚持独立自主、自力更生原则，并以此为自己发展的根本基点。但坚持坚持独立自主、自力更生，并不是闭关自守、盲目排外，而是在立足自身基础上实行对外开放，把二者结合起来。（三）课堂总结、点评这节课我们重点学习了我国对外开放方面的有关知识，知道了在经济全球化的国际大趋势下，社会主义现代化建设必须实行对外开放，积极参与国际经济竞争与合作。了解了我国对外开放的成就、格局、新形势下的基本政策和战略。这对于我们在正确地认识国际经济关系，增强社会主义优越感和民族自强意识，自觉投身现代化建设等将有重大指导作用。
人教版高中政治必修1效率优先、兼顾公平教案
教师活动：引导学生阅读教材67页，回答：什么是效率优先，兼顾公平？如何贯彻此原则？学生活动：阅读课本，认真总结，发表见解教师点评：效率优先，实质是发展生产力优先，分配制度和分配政策要以促进生产力的发展和经济效益的提高为首要目标；兼顾公平，是指社会要将收入差距控制在合理的范围内，使分配的结果能促使人们奋进，社会具有生机喝活力。坚持效率优先、兼顾公平，首先，要允许和鼓励一部分地区和个人通过诚实劳动和合法经营先富起来，先富带后富，最终达到共同富裕。其次，既要反对平均主义，又要防止收入差距悬殊；既要落实分配政策，又要提倡奉献精神。再次，必须正确处理初次分配注重效率与再分配注重公平的关系。初次分配注重效率有利于充分调动人们的积极性。在再分配中，要加强政府对收入分配的调节，调节过高收入，取缔非法收入，提高低收入者的收入水平，通过完善社会保障制度等，把收入差距控制在一定范围之内。

人教版高中政治必修4价值判断与价值选择精品教案
南极大地的水陆交接处，全是滑溜溜的冰层或者尖锐的冰棱。企鹅没有可以用来攀爬的前臂，也没有可以飞翔的翅膀，如何从水中上岸？纪录片《深蓝》展示，企鹅在将要上岸之时，要从海面潜入海中，沉潜到适当的深度，借用水的浮力，迅猛向上，飞出一道弧线，落于陆地之上。企鹅的沉潜是为了蓄势，看似笨拙，却富有成效。人生又何尝不是如此？沉潜绝非沉沦，而是勇敢、智慧、自强。如果我们在困难面前能沉下气来，不被“冰棱”吓倒，不被浮华迷惑，专心致志，自强不息，积聚力量，并抓住恰当的机会反弹向上，毫无疑问，我们就能成功登陆!反之，总是随波浮沉，或者怨天尤人，注定就会被命运的风浪所玩弄，直至精疲力竭。结合上述材料，运用《生活与哲学》知识对“价值观是人生的重要向导，有价值观的人生才是更美的人生”加以评析。7、有两名畜牧兽医专业毕业的大学生应聘到农村养猪场担任技术总监后，大力推广使用生态养猪法和中草药防疫技术，使养猪场步入了良性发展轨道。

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.
