1.归纳珠江三角洲发展基塘生产有利的地理条件。珠江三角洲地势低平,河网密布,降水充沛。北回归线从珠江三角洲的北部穿过。珠江三角洲地区发展基塘农业生产有利条件可以结合材料,归纳为三个方面:地形、气候、市场(当地和海外)。2.基塘生产将哪些产业联系起来?哪些副产品(或废弃物)被充分利用起来?这种联系对农村经济发展有什么作用?基塘生产环节将种植业(桑、蔗等)、养殖业(养蚕、养鱼)、工业(丝厂、糖厂)等几种产业紧密的联系在一起。在此环节中,塘泥、蚕沙(蚕屎)、蚕蛹、缫丝、滤泥、蔗叶等副产品被充分的回收利用。养蚕业、蔗糖加工业同塘鱼养殖业紧密结合,作为一种综合的经营,几者之间相互依存、相互促进、扬长补短,有机地循环联系起来。基本上解决了桑、蔗的肥料和蚕、鱼的饲料问题。不仅养蚕、蔗糖加工和养鱼生产稳定,而且成本也大大降低。
知识和技能 1、 了解区域工业化和城市化之间的关系,以及它们对区域社会经济发展所起的作用 。2、分析导致珠江三角洲工业化和城市化快速推进的诸多思想束缚,并通过比较,认识到对外开放政策是其中的关键因素。3、 比较珠江三角 洲的 区工业化进程的两个主要阶段,归纳出不同时期的主要发展特点,并能够结合具体案例分析工业化进程对城市化的巨大推动。 4、分析珠江三角洲地区工业化和城市化进程中的问题,并尝试评价目前的一些调整措施和发展方向。5、通过分析我国珠江三角 洲地区工 业化、城市化的发展阶段、问题与对策,了解区域工业化和城市化的推进动力和发展规律。过程与方法 利用扮演不同的社会角色来谈对珠江三角洲地区未来经济和城镇发展的设想和建议,反馈学生知识、能力、价值观发展情况和效果, 培养学生对所学所得的运用能力,并为学生的创新精神的发 展营造有利氛围。情感、态度与价值观1、通过鼓励学生主动获 取资料的做法,关注学生实践能力、综合思维能力及终身学习能力的训练。
一般情况下,凡是支持物对物体的支持力,都是支持物因发生形变而对物体产生弹力。所以支持力的方向总是垂直于支持面而指向被支持的物体。例1:放在水平桌面上的书书由于重力的作用而压迫桌面,使书和桌面同时发生微小形变,要恢复原状,对桌面产生垂直于桌面向下的弹力f1,这就是书对桌面的压力;桌面由于发生微小的形变,对书产生垂直于书面向上的弹力f2,这就是桌面对书的支持力。学生分析:静止地放在倾斜木板上的书,书对木板的压力和木板对书的支持力。并画出力的示意图。结论:压力、支持力都是弹力。压力的方向总是垂直于支持面而指向被压的物体,支持力的方向总是垂直于支持面而指向被支持的物体。引导学生分析静止时,悬绳对重物的拉力及方向。引导得出:悬挂物由于重力的作用而拉紧悬绳,使重物、悬绳同时发生微小的形变。重物由于发生微小的形变,对悬绳产生竖直向下的弹力f1,这是物对绳的拉力;悬绳由于发生微小形变,对物产生竖直向上的弹力f2,这就是绳对物体的拉力。
l.知识与技能:(1)知道摩擦力产生的条件。(2)能在简单问题中,根据物体的运动状态,判断静摩擦力的有无、大小和方向;知道存在着最大静摩擦力。(3)掌握动磨擦因数,会在具体问题中计算滑动磨擦力,掌握判定摩擦力方向的方法。(4)知道影响到摩擦因数的因素。2.过程与方法:通过观察演示实验,概括出摩擦力产生的条件及摩擦力的特点,培养学生的观察、概括能力。通过静摩擦力与滑动摩擦力的区别对比,培养学生分析综合能力。3.情感态度价值观:在分析物体所受摩擦力时,突出主要矛盾,忽略次要因素及无关因素,总结出摩擦力产生的条件和规律。二、重点、难点分析1.本节课的内容分滑动摩擦力和静摩擦力两部分。重点是摩擦力产生的条件、特性和规律,通过演示实验得出关系f=μN。2.难点是学生有初中的知识,往往误认为压力N的大小总是跟滑动物体所受的重力相等,因此必须指出只有当两物体的接触面垂直,物体在水平拉力作用下,沿水平面滑动时,压力N的大小才跟物体所受的重力相等。
1.用CAI课件模拟汽车的启动过程。师生共同讨论:①如果作用在物体上的力为恒力,且物体以匀速运动,则力对物体做功的功率保持不变。此情况下,任意一段时间内的平均功率与任一瞬时的瞬时功率都是相同的。②很多动力机器通常有一个额定功率,且通常使其在额定功率状态工作(如汽车),根据P=FV可知:当路面阻力较小时,牵引力也小,速度大,即汽车可以跑得快些;当路面阻力较大,或爬坡时,需要比较大的牵引力,速度必须小。这就是爬坡时汽车换低速挡的道理。③如果动力机器在实际功率小于额定功率的条件下工作,例如汽车刚刚起动后的一段时间内,速度逐渐增大过程中,牵引力仍可增大,即F和v可以同时增大,但是这一情况应以二者乘积等于额定功率为限度,即当实际功率大于额定功率以后,这种情况不可能实现。
三、指导第一段的背诵,点拨理解句意,强调关键词语,注重文言基础知识教学。过程中要让学生反复读背。背诵线索:时间——地点——事件——人物——环境——活动——天气——感觉。时间:永和九年,岁在癸丑,暮春之初。地点:会于会稽山阴之兰亭。事件:修稧事也。人物:群贤毕至,少长咸集。环境:此地有崇山峻岭,茂林修竹;又有清流激湍,映带左右。活动:引以为流觞曲水,列坐其次。虽无丝竹管弦之盛,一觞一咏,亦足以畅叙幽情。天气:是日也,天朗气清,惠风和畅。感觉:仰观宇宙之大,俯察品类之盛,所以极视听之娱,信可乐也。四、学生自读背诵5分钟。五、抽一至二名学生试背课文,教师可作必要的线索提示。第二课时一、听名家示范朗诵,学生小声跟读。二、复习巩固第一自然段的阅读背诵。三、朗读、解析第二自然段,理解文章“由叙入感”的写作结构。
四、品味诗歌艺术1、诗人是如何表现其品质的?运用了什么修辞手法?产生了怎样的表达效果?明确:诗句“扈江离与辟芷兮,纫秋兰以为佩”很好地体现了诗人光辉俊洁的人格。用“江离”“辟芷”“秋兰”三种香草来装饰自己,比喻自己,极其生动形象地表现了诗人自己美好的精神世界,使诗歌充满了浪漫主义气息。2、《离骚》中作者常以“香草”、“美物”来比喻自己、贤士和君王,并表达政治理想,这是《离骚》的一大艺术特色,这种方法叫做“移情法”,即不直接说出自己想说的话,而是把它寄寓于某一物上,也就是“移情于物”,这种方法在古典诗词中广泛运用,在政治不清明的时代,借用“移情”,可言难言之语,抒难抒之情。请找出相关的诗句,说说诗人是怎样运用这些比喻来表达政治理想的。
教学设想:本节课的主题是“生命之绿,璞玉心灵”,用圈点批注法解读爱绿的感情,让学生在批注中明确“绿”的象征意义,而不只是结论的传递。同时借助于阅读、感受和理解把握作者对绿的认识是不断升华的,由一般对生命希望之绿的喜爱,到与绿交往后被它的不畏强暴,永远向阳的精神所折服,最后在特定的时代背景下绿在作者的心目中已经成了我们民族不屈精神的象征。让学生评中求解,评中悟情,评中明理,评中品味。教学进程:一、导语上节课我们学习了朱自清的《绿》,初步了解了读书动笔的基本方法,这节课我们继续用圈点批注的方法来学习陆蠡的散文《囚绿记》。二、释题师:看标题,囚绿之“绿”在文中具体指什么?(一株常春藤)“囚”就是囚禁的意思,那题目就是记述囚禁绿色常春藤的经过。三、圈点、把握情节作者为什么要囚绿呢?文中除了写“囚绿”之外,还写了哪些有关绿的意念和行动?带着这样的质疑用自己喜欢的方式朗读课文,请同学们圈点出疑难字词,或结合书下注释,或同学合作解决,解决不了的,可提出来我们共同解决。标注段落节次。勾画出表现作者对绿意念和行动的句子。
【教学设想】一、选题设想《巴黎圣母院》是雨果的代表作,无论从思想内容还是艺术风格都有明显的浪漫主义特征:奇异曲折、扣人心弦的故事情节;妙趣横生、别出心裁的奇遇巧合;强烈鲜明的美丑、善恶对比;丰富生动、珠玑迸发、富有哲理意味的语言。通过导读,来消除学生对外国名著的畏难情绪,增加学生课外阅读的兴趣和信心;让学生整体把握作品,窥一斑而识全豹,让学生高屋建瓴,了解其旨意,以极为精确而又充满意蕴的文字,对名著的概述及精要部分做了介绍;引导学生自主探究,交流合作,培养学生的独立思考的学习惯,指点进行名著阅读的门径。作为导读课,教师应注意不可“越位”,在学生学习的过程中,教师的“导”固然重要,学生的“读”更不可或缺,应避免以“导读”来代替名著阅读。因此,《巴黎圣母院》的教学定位为基于课内,面向课外,以求达到以学带读,以读促学的目的。
教学过程:一、导语毛泽东在《沁园春雪》俯视封建君王“惜秦皇汉武。。。只识弯弓射大雕。”但如果历史上只有一个人可以与他相提并论,这个人只能是魏武帝曹操。“滚滚长江东逝水,浪花淘尽英雄。是非成败转头空,青山依旧在,几度夕阳红。”(《三国演义》卷首词)在历史的大浪淘沙中,有多少英雄能够经得起历史的千淘万漉而流芳百世呢?曹操应该是三国时代留下了浓重一笔的人物。老师总结,并启发他们去联系:我们学过他的《观沧海》“东临碣石,以观沧海…”还有《龟虽寿》“神龟虽寿,猷有竟时。老骥伏枥,志在千里;烈士暮年,壮心不已。”《青梅煮洒论英雄》中曾和他见过,《三国演义》电视剧播出后,大家和他也就频频见面了。《三国演义》第48回“宴长江曹操赋诗”中,赤壁之战前夕,曹操和众部将一起狂饮,他四顾空阔,心中大喜,与诸将讲述自己希望收服江南的雄心壮志。
【明确】“一夫当关,万夫莫开”言剑阁有易守难攻的险要形势,暗示中央朝廷的部队很不容易打进来,因而野心家可以据险发动叛乱,“化为狼与豺”,搞地方割据。如果割据势力之间出现矛盾冲突,难免要发生混战,结果必定是“杀人如麻”。诗人这番预言在十多年后就得到了证实:从上元二年到大历初即有段子璋、徐知道、崔旰等人相继发动叛乱。诗人的意图是要严防野心家发难。诗人从剑阁的险要引出对政治形势的描写。他化用西晋张载《剑阁铭》中形胜之地,匪亲勿居的语句,目的在于劝人引以为鉴戒,警惕战乱的发生,并联系当时的社会背景,揭露了蜀中豺狼的磨牙吮血,杀人如麻,这既是描写蜀道猛兽,又是影射政治黑暗的双关语句,表达了对国事的忧虑与关切,为诗篇增加了现实的内涵、深厚的意蕴。唐天宝初年,太平景象背后正潜伏着危机,后来发生的安史之乱,证明诗人的忧虑是有现实意义的。
(形容词短语most beautiful的构成形式为:副词+形容词,该短语在句中作定语修饰名词bird)④A good friend is someone who makes you really happy.好朋友就是能让你真正高兴的人。(形容词短语really happy的构成形式为:副词+形容词,该短语在句中作宾语补足语)[即学即练]画出下例句中的形容词短语并指明构成形式如:It is less cold today than it was yesterday.构成形式: 副词+形容词(1)Our country is becoming more and more beautiful.(2)The road is long enough.(3)The medicine is good for stomach.三、副词短语(Adverb Phrases)副词短语:指以一个副词为中心构成的短语,在句中的功能相当于副词,可以修饰动词、形容词或副词。常见副词短语的构成形式有:(副词)+副词如: much more beautifully①He did his work here yesterday.他昨天在这里工作。(副词短语here yesterday修饰动词did)②Bill did the work very well.比尔做的这份工作很好。副词短语very well修饰动词did③We are all entirely responsible for our action(副词短语all entirely, 修饰形容词短语responsible for)
【教材分析】The topic of this unit is about teenage life, which belongs to the theme context of “humans and oneself”.As teenagers who shoulder the responsibility of “Chinese great dream”, they must fully know themselves, including their strengths, weaknesses and challenges etc. They are supposed to improve themselves continuously and readily study their subjects, and thus foster their strategies and confidence in lifelong studies.This period is entitled the freshmen challenges, which mainly concerns some big challenges for new students in Senior high school. In this period, a teacher should lead students to find out what their challenges are and guide them to figure out how to crack the challenges and better themselves.

The activity topic of this section is "report an ongoing event", and the structure is the passive voice of present continuous tense. Rare wild animals are suffering from large-scale poaching, and species are on the brink of danger. Rescue operations are underway. "Being" and "suffering" are the meanings of the present progressive passive voice.The usage of present progressive passive voice is of great importance in writing a good discourse and appreciating some difficult language items, so it is vital to master it and use it flexibly in a context.1. Motivate Ss to deepen the understanding of the usage of present progressive passive voice in a fixed context.2. Enable Ss to master the usage of present progressive passive voice and use it flexibly in a context.3. Lead Ss to construct sentences or appreciate sentences used master it and use it flexibly in a context.1. Help students to appreciate the function of the usage of present progressive passive voice in a sentence2. Instruct students to write essays using the proper usage of present progressive passive voice.Look at the picture and tell me what are workers doing? What is the house being done?
The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves. The motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them. The mission of wild aid is to ban illegal trade in endangered wildlife and mitigate climate change. It aims to educate the public to reduce the consumption demand for endangered wildlife products through public publicity and improve the awareness of environmental protection.1. Improve the awareness of wildlife protection by acquiring the knowledge of wildlife protection.2. Focus on environmental protection and protection of all lives.3. Analysis of the living environment of wild animals with appropriate thinking mode.4. Skillfully use the vocabulary and grammar knowledge of this unit to cultivate self-study ability according to the unit content5. Develop cooperative learning ability through discussion and other ways1. Enable the Ss to talk about the current situation of wild animals.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.
