人教版高中地理选修3第五章第一节设计旅游活动教案
点拨：旅游地旅游资源的特色不同，可以安排的旅游活动是不一样的，直接影响对旅游者的吸引力。因此，出游前首先就需要收集旅游地旅游资源的类型、主要游览景区、景点的特色等情况。旅游地的时空可达性直接关系到旅游者从出发地到旅游地，然后再返回出发地的费用和时间。一般来说，居住地与旅游地之间的空间距离过大，会使旅行的时间过长、旅行费用过高，经济距离增加，相应地降低了旅游者的出游能力。而居住地与旅游地相距遥远，也意味着两地之间巨大的环境差异，这会增加对游客的吸引力。旅游服务设施和条件，如旅游交通方式及工具、旅游住宿条件、旅游餐饮的种类和标准、导游服务、旅行费用等信息也都在一定程度上影响着游客的选择。图5．3西藏布达拉宫和图5．4云南香格里拉两幅图片显示了西藏布达拉宫、云南香格里拉与众不同的优美景观，吸引了众多的游客前来观光旅游，成为近年来国内旅游的热点。

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分，只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition

In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention，the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste.

Step 5： After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.

香港的旅游特色在“购”，而购物旅游又进一步促进了其他要素的发展。据统计，每年进入香港的国际旅游者中有60％左右的人是为了购物，其购物费用也占全部旅游费用支出的60％左右，使香港这个弹丸之地成为世界的“购物天堂”。思考：1．从旅游六要素的角度看，香港的“购”是如何促进旅游业发展的?点拨：到香港购物是许多游客来港旅游的主要动机。“购”是香港旅游六要素的核心，促进了整个旅游业的发展。2．香港的地理位置和自由港的地位，为旅游业的发展提供了哪些有利条件?点拨：香港是自由港，商品来自世界各地，由于大部分商品不收关税，香港的商品价格就相应较低。此外，这里每年都有许多换季大减价的促销活动，能为游客提供真正的实惠。香港店铺中销售着世界各地不同特色的货品，而且大部分服务行业的从业人员都受过专业训练，态度殷勤友善，以客为先。购物成为香港吸引游客的一个重要因素，为旅游的发展提供了极为有利的条件。
人教版高中数学选修3分类变量与列联表教学设计
一、 问题导学前面两节所讨论的变量,如人的身高、树的胸径、树的高度、短跑100m世界纪录和创纪录的时间等,都是数值变量,数值变量的取值为实数.其大小和运算都有实际含义.在现实生活中,人们经常需要回答一定范围内的两种现象或性质之间是否存在关联性或相互影响的问题.例如,就读不同学校是否对学生的成绩有影响,不同班级学生用于体育锻炼的时间是否有差别,吸烟是否会增加患肺癌的风险,等等,本节将要学习的独立性检验方法为我们提供了解决这类问题的方案。在讨论上述问题时,为了表述方便,我们经常会使用一种特殊的随机变量,以区别不同的现象或性质,这类随机变量称为分类变量.分类变量的取值可以用实数表示,例如,学生所在的班级可以用1,2,3等表示,男性、女性可以用1,0表示,等等.在很多时候,这些数值只作为编号使用,并没有通常的大小和运算意义,本节我们主要讨论取值于{0,1}的分类变量的关联性问题.
人教版高中数学选修3离散型随机变量及其分布列(2)教学设计
温故知新 1.离散型随机变量的定义可能取值为有限个或可以一一列举的随机变量,我们称为离散型随机变量.通常用大写英文字母表示随机变量,例如X,Y,Z;用小写英文字母表示随机变量的取值,例如x,y,z.随机变量的特点: 试验之前可以判断其可能出现的所有值，在试验之前不可能确定取何值；可以用数字表示2、随机变量的分类①离散型随机变量:X的取值可一、一列出；②连续型随机变量:X可以取某个区间内的一切值随机变量将随机事件的结果数量化．3、古典概型:①试验中所有可能出现的基本事件只有有限个；②每个基本事件出现的可能性相等。二、探究新知探究1.抛掷一枚骰子,所得的点数X有哪些值？取每个值的概率是多少？ 因为X取值范围是{1，2，3，4，5，6}而且"P(X=m)"=1/6,m=1,2,3,4,5,6.因此X分布列如下表所示

2．避免使用过多的描写手法，避免过多地使用形容词，特别是华丽的辞藻，尽量采用直截了当的叙述和生动鲜明的对话，因此，句子简短，语汇准确生动。在塑造桑地亚哥这一形象时，他的笔力主要集中在真实而生动地再现老人与鲨鱼搏斗的场景上。鲨鱼的来势凶猛，老人的沉着迎战，机敏矫捷，都写得生动逼真。如写鲨鱼出现的情形，“当一大股暗黑色的血沉在一英里深的海里然后又散开的时候，它就从下面水深的地方窜上来。它游得那么快，什么也不放在眼里，一冲出蓝色的水面就涌现在太阳光下。”这段描写没有一个比喻句和形容词，但鲨鱼的凶猛、快捷，形势的紧迫却立刻展示在读者面前，清新洗练的叙述文字和反复锤炼的日常用语，使人读来有身临其境之感。文中对大海的描写粗犷简洁，犹如一幅水墨山水画，读来令人心旷神怡，美不胜收。

二、孟子的仁政思想1．民本思想。孟子说：“民为贵，社稷次之，君为轻。是故得乎丘民而为天子，得乎天子为诸侯，得乎诸侯为大夫。”（《孟子·尽心下》）得到百姓拥护的人才能成为天子，得到天子欢心的人可以成为诸侯，得到诸侯欢心的人可以成为大夫，可见“民为贵”的道理。孟子在尖锐复杂的阶级斗争中看到人民的力量，认为社会安定的前提在于百姓的安居乐业，这一点在当时也是有积极意义的。2．邦国的主权在民。孟子与梁惠王谈话，梁惠王问：“天下恶乎定？”孟子回答：“定于一。”梁惠王问：“孰能一之？”孟子回答：“不嗜杀人者能一之。”梁惠王问：“孰能与之？”孟子回答：“天下莫不与也。”（《孟子·梁惠王上》）意思是说，如果一个君王不嗜杀戮，那么，天下没有不愿意把政权交给这个君王的人。万章问孟子：“尧以天下与舜，有诸？”孟子说：“否；天子不能以天下与人。”万章问：“然则舜有天下也，孰与之？”孟子说：“天与之。”

五．课堂总结：巴金是现代中国不多的文学大师、思想家之一，他以丰硕的文学成果以及一生坦荡无瑕圣哲般高贵的人品，向世人证明了爱心的价值、真诚的伟大，以及天才的光芒，这位“20世纪中国的良心”，他的名字必将与鲁迅等人一样，长留青史，像北斗一样在天空闪烁！让我们记住这位老人并学习这位老人的不断进取的精神和严于解剖自己灵魂的勇气，铸造一种坦诚真实的人格。六．课外合作探究：狗与“伤痕文学”巴金此文开篇就写艺术家与狗的故事，然后写自己与狗，不光此篇写狗，他在另外的文章中也写到狗，不光巴金如此，反映文革的“伤痕文学”都经常写到狗，你如何看待这一文学现象？1．学生课外阅读“伤痕文学”查阅相关文学评论（6人一组，4人分组从网上和书籍中查阅相关文章，2人分别查阅相关评论）2．课后教师与学生交流并发表有倾向性的意见：
人教版高中语文《孔雀东南飞》教案
3.结合作品的时代背景，进一步理解“黄泉共为友”。故事发生在“汉末建安中”。当时的背景是：汉武帝时，“罢黜百家，独尊儒术”。儒家的那套伦理纲常逐渐占据了统治地位，并发展到了相当完备严密的程度。在婚姻制度方面就规定有“七出”、“天下无不是之父母”等等清规戒律。“天下无不是之父母”，这正是焦、刘悲剧的根本原因。在这一时代氛围里，在焦母的淫威下，焦仲卿敢于站在兰芝一边，表明与兰芝“结发同枕席，黄泉共为友”的坚决态度，实在是难能可贵的。面对儒家所规定的封建家长制度、封建礼教，焦仲卿举起的那面反抗的旗帜，无疑是茫茫长夜中的一道闪电！小结：对语境体察得越充分，对语言理解的深度和广度就越丰富。那么，我们对作品阅读理解的水平就越高。
人教版高中语文《诗两首》教案
二、作者简介“雨巷诗人”的大名我们早已听过,有谁知道作者的基本情况?根据学生回答总结:戴望舒生于杭州,望舒是他给自己起的笔名,出自屈原的《离骚》:”前望舒使先驱兮,后飞廉使奔属。”望舒是神话传说中替月亮驾车的天神,纯洁而温柔,多情又潇洒。戴望舒出生于3月5日,照西方星象学的说法,属于双鱼座。双鱼座的人浪漫柔情,以爱情为生命的养分,意志薄弱,喜好幻想,逃避现实,优柔寡断。戴望舒就是典型的双鱼座性格。三,诗歌赏析:1、有这样温柔多情的笔名,又有这样浪漫柔和的性情,戴望舒笔下流淌出来的诗句也必然是细腻多情的,下面就让我们共同欣赏这首《雨巷》。师配乐朗诵。
人教版高中语文《短新闻两篇》教案
罗森塔尔突破了“客观报道”“零度写作”的框框，把自己和其他参观者在奥斯维辛访问时的感受当做文章的主要内容来写，传达出每一个良知者的共同心声。教师总结：细节描写是耐人寻味的。文章没有阴森恐怖的镜头，没有血腥的画面，只是重现了新闻的事实真相，但透过细节却能引发人们对生命，对人性的思考。在作者看似平静的叙述中抒发了对德国纳粹残酷暴行的沉重控诉，更表达了作者对自由、和平与祥和的向往四、拓展延伸：《奥斯维辛没有什么新闻》这一作品本身的价值在哪？社会价值又在哪，能不能从这两个角度思考，几人合作试写一段颁奖词？范例：《奥斯维辛没有什么新闻》突破新闻“零度写作”原则，着眼细节，以冷峻的视角，深沉地描述了今天的奥斯维辛集中营纪念馆。在恐怖与快乐、战争与和平、历史与现实的反差中，它召唤起人们关于灾难的记忆、关于生命的思考、关于人性的自省。它的发表充分地表现了一个新闻记者的使命感，更以迫人的力量震撼生者的心，成为新闻史不朽的名篇。
