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.

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.

A生产方式是人类社会存在和发展的基础人要生存必须有吃、穿、住、用等物质生活资料,只有生存问题解决了才能谈得上社会的存在和发展,才能从事其他的活动(教育、艺术、体育、政治)。而要获得物质生活资料,必须从事物质资料的生产劳动。在这一活动中,形成了现实的生产力和生产关系,即生产方式。【思想教育】落后必然挨打,我国大力发展经济,就是为了发展生产力。发展是硬道理,中国解决一切问题的关键在与自己的发展。要积极支持改革开放,积极投身于经济建设中去。现在学好知识将来教育育人,为社会培养更多的合格人才。B生产方式决定着社会的性质和面貌社会生活纷繁复杂,包括经济生活、政治生活、精神生活、婚姻家庭生活等许多方面。这些方面都受生产方式的制约,有什么样的生产方式,就有什么样的社会结构;不同的生产方式,表现为不同性质的社会形态。社会的整个面貌只能从生产方式中得到科学的说明。【举例】家庭联产承包责任制的产生与推广1958年的人民公社化运用曾使中国农民在劳动和分配上都实行绝对的平均主义,大锅饭的结果是饭越吃越少,人越过越穷。
b哲学为具体科学提供世界观和方法论的指导每一个时代的具体科学的发展,总是受到这个时代哲学思想的影响和支配。任何一个科学家都有自己的哲学信仰,都用一定的哲学世界观来指导自己的研究。缺乏正确的世界观和方法论的指导,就会在研究中失去正确方向,甚至陷入混乱和失败。【举例】牛顿晚年误入歧途牛顿早年在自发的唯物主义世界观的指导下,发现了万有引力定律,谱写了人类物理史上的辉煌篇章。他谦虚地说,他是站在巨人们的肩膀上,拾取了知识大海里一个晶莹美丽的贝壳。但在他的后半生,居然虔诚地投入上帝地怀抱,用25年的时间研究神学,写了100多万字有关神学和宗教的书稿。牛顿是一个虔诚的宗教信徒,自幼受到信奉上帝的教育,这对他的世界观影响极深,加之他所处的时代是形而上学统治自然科学的时代,在错误的世界观的支配下,他将解释不了的现象求助于上帝,如“从上帝那里去寻找行星围绕太阳公转的第一推动力”,结果一事无成。
材料说明了什么?探究二:材料分析:2005年12月13日至18日,WTO第六次部长级会议在香港召开。会议经过谈判通过了《部长宣言》,规定发达成员和部分发展中成员2008年前向最不发达国家所有产品提供免关税、免配额的市场准入;发达成员2006年取消棉花的出口补贴, 2013年年底前取消所有形式农产品出口补贴。材料体现了世界贸易组织在国际经济贸易领域中发挥哪些作用?探究三:P97:A、这些图示,反映出我国利用外资哪些特点?。B、能为我国提高外资利用水平提出些建议吗?探究四:材料展示:我国是人口众多的发展中大国,全国居民每天消费总额达到37亿元。每天消费粮食75万吨,相当于一个县级商品粮基地的全年产量;每天消耗猪肉6万吨,食油1万吨,糖1.6万吨,鲜蛋1.8万吨。每天购买杂志600多万册,报纸5000多万份,需要400量中型载货汽车才能装载。
思考提示在阶级社会中,社会基本矛盾的解决主要是通过阶级斗争实现的,阶级斗争是推动阶级社会发展的直接动力,当旧的生产关系严重阻碍生产力发展,需要进行变革时,代表旧的生产关系的没落阶级却不会自动退出历史舞台,利用旧的上层建筑维护自己的统治,只有代表新生产力发展方向的阶级通过社会革命,推翻没落的阶级统治,才能解放生产力,推动社会向前发展。所以,阶级社会的进步往往是通过激烈的社会革命实现的。但是,社会主义社会与阶级社会不同,这是因为,社会主义社会中,生产力和生产关系、经济基础和上层建筑之间的矛盾是一种非对抗性矛盾,不需要通过一个阶级推翻另一个阶级的阶级斗争的方式来解决,只能通过改革实现社会的发展,通过对生产关系和上层建筑进行改革,实现社会主义的自我完善,从而促进社会的发展。所以,我国经济体制改革是在坚持社会主义制度的前提下,改革生产关系和上层建筑中不适应生产力发展的一系列相互联系的环节和方面。
3.柏拉图(公元前427一前347)古希腊哲学家。生于雅典。苏格拉底的弟子,亚里士多德的老师。他曾在雅典创办学园,收徒讲学,逐步建立起欧洲哲学史上第一个客观唯心主义体系。他也是欧洲哲学史上第一个有大量著作传世的哲学家。他提出世界的本源是“理念”,现实中的事物都是“理念”的摹本。人的知识来源于对“理念”的回忆。柏拉图的哲学思想对后世影响很大,有人说,柏拉图之后的欧洲哲学思想都是对柏拉图思想的注脚。4.黑格尔(1770—1t53l)19世纪德国古典哲学家,客观唯心主义者、辩证法大师。生于斯图加特,卒于柏林。出身于官僚家庭。曾在图宾根神学院学习哲学和神学。大学毕业后,做过几年家庭教师。后任报纸编辑、中学校长、大学讲师、教授和柏林大学校长。黑格尔是在法国革命的直接影响下成长起来的,青年时朝气蓬勃,非常激进。他还深受著名诗人歌德的影响。1818年,他到柏林大学任教后,公开美化普鲁士专制制度,号召人们同现实妥协。
(2)历史课本中历朝历代的文化发展。(3)政治生活中关于综合国力竞争的相关知识。(4)了解文化产业的发展,深入体会知识经济、文化经济现象。五、【方法点津】:(1)坚持理论联系实际的方法,感悟文化现象,理解文化内涵,分析文化的作用,增强文化学习的自觉性。(2)自学探究。以课本的简单提示为线索,深入探究文化与经济、政治的相互交融,探究文化在综合国力竞争中的地位和作用。(3)集体讨论。针对当前国际竞争的实质,探讨我国应如何发展文化产业、发展文化生产力、增强文化竞争力;讨沦为更好地应对文化竞争,作为中学生目前应做好哪些准备。六、【课文导语】:文化,一个我们十分熟悉的词汇。然而“熟知并非真知”。有人说,文化是知识;有人说,文化是艺术。究竟什么是“文化”?只要在社会生活中细细体味,我们就能真切地感悟“文化”的内涵与文化的力量。
一、教材分析这一课对学生来说还是有点难度的,比较抽象,和同学们的生活离得比较远。这一课也是第四单元的点睛一课,重点。可以列举当前我国社会主义精神文明建设的事例,说明必须坚持马克思主义的指导地位,用“三个代表”重要思想统领社会主义文化建设;理解发展先进文化,就是发展面向现代化、面向世界、面向未来的,民族的科学的大众的社会主义文化。例如,“五个一工程”等奖项;“希望工程”等活动。让学生来理解我国社会主义文化的发展。二、教学目标(一)知识目标(1)当代中国先进文化的科学内涵及文化建设的指导思想理解:(2)社会主义核心价值体系的地位、内容及要求,(3)坚持马克思主义指导地位的必要性和重要性(4)引领中国先进文化前进方向的永不退色的旗帜分析:运用相关知识,,说明必须用“三个代表”重要思想统领社会主义文化建设
刘绍棠,中国当代著名乡土文学作家,1936年2月出生于河北通县(今北京通州区)大运河畔的儒林村,1949年开始发表作品,一生留下了500多万字的乡土文学作品,包括《地火》《京门脸子》等多部长篇小说,《蒲柳人家》《运河的桨声》等多部中篇小说,以及《青枝绿叶》《蛾眉》等多部短篇小说集。他的作品在国内多次获奖,在国际上亦有影响。刘绍棠的作品内容各不相同,但都艺术地再现了其家乡大运河畔不同历史时期的风土人情和社会风貌,描绘了充满诗情画意的乡风水色、世俗人情。20世纪80年代以来,刘绍棠不遗余力地倡导乡土文学,创作上坚持“中国气派,民族风格,地方特色,乡土题材”。文学评论家指出,他的作品格调清新淳朴,乡土色彩浓郁,形成了独具特色的大运河乡土文学风格。
五、课后反思课后组织学生讨论对本课的感受,同学们都非常乐意采取这种上课方式,既可以通过资料的搜集、整理提高自身信息采集的能力,也能够提高自己学习积极性,变枯燥为生动。本人在教学中也深深地感到:一方面,充分发挥学生的主体作用,有利于启发同学的思维,培养自主思考的能力。而充分利用网络的教学功能,将现代信息技术和学科教学很好地结合了起来。只有调动全体同学的积极性、主动性、创造性,我们的教学才能有生命力;另一方面,光有学生的活动也不行,虽然学生能够积极投入地利用互联网搜集并动手制作课件,在课堂交流中能很好地进行发散思维和创造性思维,但其集中思维和抽象性思维还存在一定的缺陷,主要体现在对搜集的材料的取舍是以及对知识点的归纳和深化方面,所以在充分发挥学生的主体作用的同时应该也必须重视教师主导作用的发挥,引导学生由形象到抽象、由发散到集中、由演绎到归纳的思维能力的逐步提高。
代中国人民的四大发明,古希腊人的哲学与艺术成就,占代印度人民在宗教和数学方面的成就等,都以其鲜明的民族特色}:富J,世界文化,共同推动了人类社会的进步和发展。总之,尊重和保存不同的民族文化,是人类生存和发展的基础。◇课堂探究:(1)对那些面临失传的占老民族文化,有人反对进行抢救和保护,认为应当顺其自然地让它们被历史淘汰。你同意这种看法吗?(2)你认为,我们还有哪些独特的文化形式可以申报人类口述和非物质遗产?◇探究提示:(1)文化遗产是一个民族的“身份证”,从文化意义上标识出一个民族的个性和一个民族的历史记忆。文化遗产是人类社会发展的见证,是人类文明的重要载体。文化遗产体现着一个民族独特的思维方式和文化价值,是民族的根基,是历史的纪念碑。文化遗产既属于一个国家、一个民族,也是全人类的共同财富。文化遗产具有不可再生性的特点,所以对那些面临失传的古老民族文化,我们不能坐视不管,要进行及时有效地抢救和保护。
