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。
Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.
Step 4 PracticeRead the conversation. Find out which words have been left out.Justin: Linlin, I’m going to Guizhou Province next month. I’m super excited! Any recommendations for places to visit?Linlin: Wow, cool! Guizhou is a province with a lot of cultural diversity. Places to visit...well, definitely the Huangguoshu Waterfall first.Justin: What’s special about the waterfall?Linlin: Well, have you ever heard of the Chinese novel Journey to the West ?Justin: Yes, I have. Why ?Linlin: In the back of the waterfall, you will find a cave, which is the home of the Monkey King.Justin: Really? Cool! I’ll definitely check it out.Linlin:And I strongly recommend the ethnic minority villages. You’ll find Chinese culture is much more diverse than you thought.Justin:Sounds great, thanks.Answers:Justin: Linlin, I’m going to Guizhou Province next month. I’m super excited! Do you have any recommendations for places to visit?Linlin: Wow, that’s cool! Guizhou is a province with a lot of cultural diversity. What are some places to visit in Guizhou ? Well, definitely the Huangguoshu Waterfall is the first place to visit in Guizhou Province.Justin: What’s special about the waterfall?Linlin: Well, have you ever heard of the Chinese novel Journey to the West ?Justin: Yes, I have heard of the Chinese novel Journey to the West . Why do you ask if I have heard of the Chinese novel Journey to the West?Linlin: In the back of the waterfall, you will find a cave, which is the home of the Monkey King from Journey to the West.Justin: That’s really true? It’s Cool! I’ll definitely check it out.Linlin:And I strongly recommend the ethnic minority villages on your trip to Guizhou Province.

Step 4: Listen again and decide if the following statements are true (T) or false (F).1 It was the first time Chen Liyan's story was reported. T口 F口2 Chen found 10,000 yuan in a small plastic bag in Taiyuan railway station口 F口3 Wang Zheng apologized to Chen because he couldn't offer her more money. T口 F口4 Chen took out a large loan to cure her daughter, T口 F口5 Wang set up a fundraising website for Chen's daughter after Chen told him about her situation. T口 F口Step 5:After listening, discuss the questions.1 What kind of person do you think Chen Liyan is?Chen Liyan is generous and honest because she returned a large sum of money to the owner.2 Did Chen return the money because she didn't need it?No. She returned the money because it was the right thing to do. Evidence for this is that she refused to accept the reward money because she felt that it had not been earned. 3 Is it common for people to do what Chen did?It depends on the culture. In some countries it is quite common to return money that has been found. In other countries, people believe "Finders are keepers!" 4 How did Wang Zheng feel about the return of his money?He must have been very happy and relieved to have gotten his money back. We know this because he thanked Chen repeatedly and even offered her a reward.5 Why did Ma Dongbao tell Wang about Chen's family?He must have had great sympathy for Chen and her daughter and wanted to help them.'We know this because he arranged help for them. 6 How did the news reporter feel about Chen's actions?The news reporter felt that it showed that money wasn't the most important thing in life. We know this because the reporter told us that this is what Chen believes. and then said, “that's a great attitude to take."
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
四.设计反思我在设计本课时,希望通过情境的创设充分再现历史,并利用多媒体辅助教学,破重点、化难点,让学生主动参与到学习过程中,从而突破狭小的教室空间,让学生真正做到感知历史,立足现实,展望未来。自主,交流、合作、探究是课程改革中着力倡导的新型学习方式。课堂教学中如何开展小组合作的探究学习存在着很多困难,首先是课堂教学时间有限,如何体现面向全体,给每个学生以机会?再次,历史问题的讨论只能依托于史料才能使讨论不沦为空谈,课堂上通过网络提供大量的史料(文字、图片或其他),势必不能有充分时间让学生阅读分析。如何解决这些问题呢?措施一:要形成较固定的历史学习合作小组。选定一位同学担任组长,负责协调措施二:要设置有利于学生探究的问题情境措施三:要把课堂教学与课外学习结合起来。在课前就印发相关的材料,或引导学生去查阅相关的资料,让学生有个充分的阅读、思考、交流的时间,是保证课堂上小组交流能成功实现的一个前提
课前活动:分成四组,对南京三个住房地段进行调查,新街口夫子庙、板仓、仙林,对住房居民进行问卷调查,自行设计调查问卷,分析该地段的房价要求,居民的要求,居民为何要在该地段购买住房,基础设施设置等等其它与居民购房有关的因素。◆设计意图:利用课前小组探究形式对所学问题进行相关调查,不仅让学生掌握知识了解知识来源于社会还能培养学生深入生活交际表达能力以及合作探究能力;3.问题设计同学们,不知道你们在调查过程中是否发现一个问题,郊区的房子,特别是别墅,都是些高档居所,许多有钱人的居住场所,那为什么会这样呢?伴随着城市化进程中居民都往城里挤,为什么还会有许多有钱人往郊区搬呢?这就是我们今天要研究的第二个问题:逆城市化。◆设计意图:承转过渡知识,从购房选择因素的学习过渡到郊区化的学习,同时培养学生发现问题的能力,给学生以启迪。
第11段很短,只点出了这是“在妇女身上搞不育试验的地方”,但在最末又加了一句“否则他会羞红了脸的”,这是为什么?那肯定是一个极为肮脏,极为残酷的地方。据资料记载:当时的希特勒制定一项令所有被征服或占领国家的民族充当奴隶并且逐渐消亡的隐密性种族灭绝计划——高效率、大规模的强制绝育。为此,数以百计的纳粹医生、教授、专家甚至护士,在行政管理专家的通力合作下,相继提出了几十种绝育方法,十余种实施方案,并且在奥斯维辛、拉芬斯布吕克、布亨瓦尔特、达豪等十多个大型集中营内对数以万计的犹太、吉普赛囚犯、因从事抵抗运动而被捕的政治犯和男女战俘进行了残酷的手术试验,造成他们大量死亡或者终身残疾、终身不育。这样残酷的毫无人性的手段,任谁也不愿看到。
二、说学生本届高一学生经过了三年初中课改,在心理上,他们渴望表现的欲望和自主探究的欲望比较强烈,对有兴趣的知识表现出高度地热情,并具有一定的团结协作能力,但还是应该正视一个并不乐观的现实——在写作方面,学生知识还停留在简单的记叙及表达方式综合运用上,至于巧妙构思、谋篇布局很是空白。即便已经经过高中一个学期的学习,但还是有大部分学生依然基础较为薄弱,甚至出现不知从何下笔的现象。三、说教法与学法“老师搭台,学生唱戏”1、教法:本课将安排两课时(一课时学习一课时练笔),采用 PPT 多媒体课件教学,尝试用角色扮演法、图片展示法和多媒体教学等方法,教学中应该重视学生的参与性和探究性。2、学法:学生应该充分利用多角度创设的学习情境来激发自身学习的兴趣和热情,分组讨论,小组互助等形式让学生积极自主参与、进行问题探究学习。理论依据:建构主义理论“学生是学习的中心”的阐释,教师应该做学生主动建构意义的帮助者、促进者。
当代社会生活的变化比以往任何时代都要快。语言尤其是词汇记录了这些发展变化,因而也涌现了大量的新词新语。据统计,近几年每年大约要出现1000个左右的新词新语,而字典、词典的多次修订、增补就反映了这种情况。但相对来说,也有一些流行语又逐渐受到冷遇,甚至退隐。为了更好的对新词新语与流行文化作一番检视与探究,那让我们考察一下它们是怎么产生的吧?老师先给同学们列举四种途径:大屏幕3。同学们能再举出以上途径的一些例子吗?老师列举(4)其实不只这些,那还有哪些途径呢?找同学说并举例。说的非常好,请同学们看老师的例子,总结(5)。从新词新语的产生途径可以看出,这些鲜活得像画一样的新词就是这个时代跳动的血小板,它涉及当代社会的重大事件、现象与时弊,以及人们日常生活的各个层面如人生意义、生活方式、爱情、友情、就业、消费、时尚等,时代性强,传播面广,反映着当代社会时局与人们文化心态的变化。
师:“两开”是什么意思啊?注解里是怎么说的?第二次开,也就说他在这个地方已经待了两年了,这里是他回家的路途中,是不是?路途中他停留了两年时间。好的,你先请坐。你觉得残菊不能两开,在理解上好像存在一些误差。赵勇:因为菊花古往今来代表着对家乡的思念。师:菊花代表对家乡的思念?(下面学生齐笑)这种说法牵强了些,菊花在古代象征着高洁,梅兰竹菊是四君子嘛。赵勇:写这首诗时,他已经打算回故乡了,所以不应该写“残菊”,写“残菊”的话……师:事实上,他回不了故乡。好的,请坐。再想想,“残菊”意味着什么?破败。“丛菊”呢?茂盛。那这里说“两开他日泪”,“两开”是什么意思?开了两了次了,这说明他在这里已经待了两年了。那“他日泪”又是什么意思?赵勇:应该是他看到这里的菊花开得这么茂盛,就想到了故乡的菊花也是开的茂盛的时候。如果是“残菊”的话,那故乡的菊也会开得很残败。(下面学生齐笑)
1、汉武帝尊儒的措施:(1)政治方面:起用很多儒学家参与国家大政。他规定,地方定期选出孝子、廉吏当中央任官,甚至还擢升平民、儒士为相。这明显扩大了官员的队伍,提高了官员的文化素质,巩固了封建统治基础,成为汉武帝文治武功的重要组成部分。也给后世封建王朝在用人方式方法上面提供了宝贵的借鉴和启迪。(2)思想方面:采纳董仲舒的建议,“罢黜百家 独尊儒术”(3)教育方面:儒家经典“五经”为国家规定的教科书。兴办太学和设立地方学校进行儒学教育。公元前136年,汉武帝正式规定《诗》、《书》、《礼》、《易》、《春秋》为“五经”;前124年,又在长安兴办太学,规定太学生员为博士弟子,一律由儒家五经博士负责教授,学完经考试合格后即可到政府任官。这是封建国家利用政权的力量兴办教育、提倡儒学,其必然对整个社会的教育事业有一定的导向作用。
1)他们在初中的生物学学习中已具备了一定的关于光合作用的基础知识,也做过“绿叶在光下制造淀粉”这个实验。2)他们具备物质转变和能量变化等相关的化学知识。3)在前面的《降低化学反应活化能的酶》一节的学习中已经学习过简单的对照实验和相关的实验设计原则,使本节课最后的实验设计得以顺利进行。4)他们具有一定的 分析问题的能力,实施问题探究教学是可行的。三、教法和学法根据上述对教材和学生的分析,本节采用以下教法和学法:1)实验法:以实验说明结论。生物学的教学就是实验的教学过程,实验的展示形式有学生分组实验、老师示范实验、动画和图片演示实验等,让实验现象说明问题,而不是直接让学生记住结论。2)问题探究教学发:以问题引发兴趣。整个教学过程要设置好问题,层层展开,层层递进,让新知识与旧知识融为一个整体,让学生在步步上升中攀登到知识的顶峰。3)比较学习法,同时采用多媒体辅助教学,解决光合作用抽象的过程。
1、教材内容本节是人教版普通高中标准实验教科书生物必修2《遗传与进化》的第五章《基因突变及其他变异》的第一节内容。本节介绍了可遗传变异的两种类型:基因突变和基因重组,其中基因突变从实例对镰刀型细胞贫血症的分析入手,引入基因突变的概念,然后详细阐述基因突变的原因和特点、意义。在阐述自然状态下基因突变的频率很低时,教材用实例说明在一个足够大的群体中,即使基因突变频率很低,突变个体仍然会占有一定的数量。这个实例体现了生物在进化过程中“变”与“不变”的平衡,有助于学生理解基因突变在生物进化中所占有的重要地位。在基因重组部分,教材设置了“思考与讨论“的栏目,旨在让学生利用数学方法,通过计算,体会基因重组机制提供的极其多样的基因组合方式,从而帮助学生理解基因重组是生物多样性形成的主要原因。正文中则简要阐述了基因重组的概念、类型和意义。本节内容引导学生从分子水平上理解遗传物质如何引起生物变异的。
投影上海市的卫星城镇建设、交通改善图以及住房图等,探讨上海为解决城市化的问题做了哪些方面的工作?进一步引导思考总结对于城市化带来的问题,除了上海市的做法,你还有什么想法?◆设计意图:借上海的例子一方面引导学生解决问题的思路,让学生自己掌握城市化问题及措施,活跃思维;另一方面帮助学生树立学习优秀的意识;4.活动设计.未来展望——生态城市课本38页的活动,结合合肥市环城公园,解释生态城市。◆设计意图:进一步让学生认识到人地协调的重要性,牢固树立可持续发展的观念。5.活动设计分析南京的城市化过程中存在哪些问题,除了共性外,还有没有自己的个性问题?对于问题展开讨论,并提出相应的解决措施。◆设计意图:结合身边的地理,落实乡土地理的教育,激发学生热爱家乡,从身边的环境小事做起,落实环境教育。
4、【自主探究】巴山夜雨的成因③材料三:三国时期,诸葛亮于农历6月的一天,在葫芦峪设下伏兵,打算用火攻全歼司马懿。这一天,晴空万里暑热难耐,真乃火攻之良机。诸葛亮依计将司马懿之众诱入谷中……然而,正当大火冲天,司马懿全军行将覆灭之时,一场大雨不期而至,大雨浇灭了诸葛亮扶汉反魏的壮志,使他喊出了“谋事在人,成事在天,不可强也”的千古悲歌。【设计理念】前后呼应,发散思维。通过自主探究,学生各抒己见,完成对热力环流整个知识框架的一个总结,既考查了学生的课堂学习效果,又锻炼了学生知识的迁移能力,并认识生活中的地理规律,用生动的语言拉近学生与大气理性知识的距离,体会到地理学科的重要性。【提问】如果将白天换成夏季,将夜间换成冬季,情况又会怎样?城市与郊区之间也存在着热力环流——城市风,它们是怎样形成的?了解城市风的出现有何重要意义?如果地球上在赤道和两极之间存在热力环流,这个热力环流应该怎样?这几个问题,请大家课后慢慢思考。
(一)教材的地位与作用本节教材包括三方面的内容,(1)全球气候在不断变化之中。(2)全球气候变化的可能影响。(3)气候变化的适应对策三方面说明气候变化及其对人类活动的影响。从标准的要求看,学习的重点不在全球气候变化本身,而是把全球气候变化看作是客观存在的事实,从而探讨全球气候变化对地理环境及人类活动的影响。从资料中可以看出本节教学内容涵盖的时空跨度非常大,思维的链索很长很广,许多问题涉及到学科的前沿及人类所关注的热点,因此,本节课对学生而言既有趣味性,又有挑战性。 (二)教学目标(1)知识与技能目标:1.通过全球气候的长期演变图,学生了解全球气候处在波动变化之中。2.通过资料认识全球气候一直处于变化之中并呈现一定变化周期,了解全球气候变化对地理环境及人类活动的影响,能够提出一些气候变化的适应对策。
