倾斜角与斜率教学设计人教A版高中数学选择性必修第一册
(2)l的倾斜角为90°,即l平行于y轴,所以m+1=2m,得m=1.延伸探究1 本例条件不变,试求直线l的倾斜角为锐角时实数m的取值范围.解:由题意知(m"-" 1"-" 1)/(m+1"-" 2m)>0,解得1<m<2.延伸探究2 若将本例中的“N(2m,1)”改为“N(3m,2m)”,其他条件不变,结果如何?解:(1)由题意知(m"-" 1"-" 2m)/(m+1"-" 3m)=1,解得m=2.(2)由题意知m+1=3m,解得m=1/2.直线斜率的计算方法(1)判断两点的横坐标是否相等,若相等,则直线的斜率不存在.(2)若两点的横坐标不相等,则可以用斜率公式k=(y_2 "-" y_1)/(x_2 "-" x_1 )(其中x1≠x2)进行计算.金题典例 光线从点A(2,1)射到y轴上的点Q,经y轴反射后过点B(4,3),试求点Q的坐标及入射光线的斜率.解:(方法1)设Q(0,y),则由题意得kQA=-kQB.∵kQA=(1"-" y)/2,kQB=(3"-" y)/4,∴(1"-" y)/2=-(3"-" y)/4.解得y=5/3,即点Q的坐标为 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)设Q(0,y),如图,点B(4,3)关于y轴的对称点为B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由题意得,A、Q、B'三点共线.从而入射光线的斜率为kAQ=kAB'=-1/3.所以,有(1"-" y)/2=(1"-" 3)/(2+4),解得y=5/3,点Q的坐标为(0,5/3).

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？）

４、主旨 哪一联明确地点明全诗题旨？表达了作者的什么感情？试做分析 颈联。 菊花开在秋天，所以这 “ 丛菊 ” 回应了诗题中那个 “ 秋 ” 字。 “ 他日 ” 可以指过去也可以指未来，在这里是指过去。“丛菊两开”，指诗人于 765 年离开成都，原打算很快出峡，但这年留居云安，次年又留居夔州，见到丛菊开了两次，还未出峡，故对菊掉泪。秋菊两度盛开，使诗人再次洒下往日流过的眼泪。“开”字双关，一谓菊花开，又言泪眼随之开。此时他仍然滞留在他乡，他始终没有放弃回乡的打算。孤舟可以系住，使其不能泛诸中流，但诗人的心是系不住的。他的心早已越过江河，越过关山，飞到了长安。所以，一叶靠岸系绳的孤舟，始终都牵动着诗人的故园之思。这一联是全篇诗意所在。孤舟本来只能系住自己的行踪，却把诗人的思乡之心也牢牢地系住了，故见舟伤心，引出故园之思，表现出思乡之情的深沉浓烈和欲归不得的无奈与凄伤，为文章的主旨句。
人教版高中语文必修3《学会宽容 学习选择和使用论据》教案2篇
评价分析法，就是引述事例后，对所引述的事例作适当的评价，从而使自己的观点得到印证。例如，在论“节俭”时，引用了“曾国藩以俭戒子，其子曾纪泽终成出色的外交家；方志敏居官不贪，一生清贫，千古留名”的事实后，接着进行分析：是的，“俭者心常富”，节俭能培养人同困难作斗争的勇气和意志，而这正是一个人立业最重要的素质。从这个意义上说，有人说饥饿是人生的佐料，吃苦是一种资本也不无道理，而自觉和戒奢尚俭则更是促人修身养性，磨炼意志的有效途径。这里，作者紧扣论点，对论据进行了评价性分析，这种评价分析使作者的观点得到强化。（四）因果分析法因果分析法，就是抓住论据所述的事实，并据此推求形成原因的一种分析方法。事出必有其因。我们可以依据事物发展变化的因果关系，由事物发展变化的结果，推导出产生这种结果的原因，从而揭示出一定的生活规律，使事例有力地证明观点。
人教版高中历史必修3“罢黜百家独尊儒术”教案2篇
战国阴阳五行家邹衍认为，历史中的朝代更替是由于五德运行产生的影响。按照邹衍的学说，每个朝代必须与五德之一相连，因此，这个朝代就应当遵循这五德之一的要求来运转。董仲舒修改了这个理论，认为朝代的更替不是依循五德运行的顺序，而是依循“三统”，即黑统、白统、赤统的顺序。他在《三代改制质文》中说：每个朝代都依循一统，每统又各有其为政的系统。按董仲舒的说法，夏朝代表黑统，商朝代表白统；周朝则是赤统。夏、商、周三朝完成了这一历史循环。之后，历史又开始一次新的循环，新的朝代又应当代表黑统。继承周朝统治的既不是秦朝，也不是汉朝，而是孔子，他承受天命，创立了黑统。孔子所受天命，不是一种“法统”，而是一种“道统”。董仲舒说：“《春秋》大一统者，天地之常经，古今之通谊也。今师异道，人异论，百家殊方，指意不同，是以上亡以持一统；法制数变，下不知所守。臣愚以为诸不在六艺之科孔子之术者，皆绝其道，勿使并进。邪辟之说灭息，然后统纪可一而法度可明，民知所从矣。”
