The Internet celebrity Gao Yifeng. Years ago, he owned 5 companies and the staffs over 1,000, but during the economy crisis, he became nothing but debt. He was so worried that his hair became white overnight. There was a time when he wanted to killed himself. But after listening to the song Start Over by Liu Huan, he decided to cheer himself up. He started a steamed bun shop and gradually became a national chain shops. Now he became successful again.Walter Haddon said, “Music is the medicine of a troubled mind.” Music contains such a pleasant and inspiring force. Music gave him courage and bravery. When he listened to the song, it made his spirit fly like a kite in the wind. Music gave him strength and brought him relief. It was the rock I leant on to become strong and to get through those hard times. I hope none of us have to go through the same kind of suffering that he did. At the same time, we all go through various periods when we feel sad or alone. During those times, music can help us in the same way that it helped him. I hope we all will somehow begin to treasure music and make it a part of our life. Thank you for your listening !5.Revise your writing each other.Does he/she explain how music has changed his/her/someone else’s life?Are some of the rhetorical devices included and used properly ?Does he/she talk about how music makes him/her/someone feel?Is the first word in each sentences capitalised?Does he/she use correct punctuation ?

My topic is: love music like love yourself.Music is like the air we need to maintain our normal lives around us. You can't imagine how terrible a world without music would be. Movies and TV shows have no music, only dry conversations and scenes; mobile phones only vibrations; streets only noisy crowds; cafes, western restaurants only depressed meals. What a terrible world it is!As a student, I hope we all can enjoy the fun brought by music in our spare time. Instead of just listening to music, we can even make our own music. Let's enjoy the fun of music!Thanks again for your attention!
科学家预测,就地区而言,位于低纬度的大部分国家,农作物的产量将减少;而位于高纬度的国家,农作物产量有可能增加。由于不少发展中国家位于低纬度地区,因此,气候变化的这种区域差异性,可能会使发展中国家所面临的问题更为严峻。板书:3全球变暖将加剧水资源的不稳定性与供需矛盾。介绍:全球变暖会影响整个水循环过程,可能使蒸发加大,改变区域降水量和降水分布格局,增加降水极端异常事件的发生,导致洪涝、干旱灾害的频次和强度增加,以及地表径流发生变化。随着径流减少,蒸发增强,全球变暖将加剧水资源的不稳定性与供需矛盾。转折:既然全球变暖会引起很多不利影响,那么作为人类应如何面对这一挑战呢?这就是我们要讨论的第三个问题。板书:三、气候变化的适应对策讨论:请大家阅读结合教材P53气候变化的适应对策部分讨论人类应如何面对全球变暖这一问题 呢?
1.改善城市环境:治理河流、控制大气污染物、大力加强绿化建设为改善城市环境,上海市全面展开对大气、河流、噪声等多方面的治理工作。如苏州河的治理、降低城市污染物浓度、加强绿化建设,截止1990年,市区绿化覆盖率达到20.3%。2.改善城市交通、改善居住条件扩宽主干道,修建环城公路,修筑了南浦大桥和扬浦大桥,新修城市高架公路和地铁,改造住宅。3.控制城市规模建立卫星城,开发新区,有效地控制城市中心区的规模。思考:什么时候许多国家采取措施保护和改善城市环境?你认为可以采取哪些措施来保护和改善城市环境?上海市保护和改善城市环境的措施:上海的卫星城有哪些?上海新建了哪个新区?目前浦东新区在上海的地位如何?建立卫星城和开发新区可以起到什么作用?上海市为改善交通条件,做了哪些工作?
过渡:在实际生活中,城市内部空间结构并非完全按照这一经济规律呈现,而是更具复杂性。这说明除了经济因素外,还有很多其他因素在起作用,请大家结合你的认识、图2.9和案例1:纽约市的少数民族区谈谈你的看法。(2)其他因素I收入——形成不同级别住宅区的常见原因。有能力支付昂贵租金和选择最佳居住环境的人,其居住地往往形成高级住宅区。II知名度——城市内某些地区在历史、文化或经济方面具有很高的声誉,这往往会吸引更多新的住宅或商场建在该处,以提高其知名度。III种族聚居区的形成——在有些城市的某一区域内,如果某个种族或宗教团体占优势,就可能形成种族聚居区。如纽约市的唐人街、哈林区、小意大利区等。IV历史因素——城市的建筑物和街道设计可以维持久远,早期的土地利用方式对日后的功能分区有着深远的影响。
1.生产上的联系:有投入——产出的关系工业生产的过程复杂,工序繁多,往往需要经过多家工厂的加工才能完成一种产品的生产过程。因此,在这些工厂之间就存在着产品与原料的联系。一家工厂生产的产品是另一家工厂的原料,这两家工厂之间就形成了工序上的工业联系。2.非生产上的联系:如地理空间上的联系布局在同一个工业区内,共同利用工业区的道路、供水、供电、通信等基础设施以及其他生产、生活服务设施,或者共同利用当地廉价的劳动力,形成了空间利用上的工业联系。我国许多地方的经济技术开发区就是建立在这种工业联系基础上的。(二)工业集聚1.形成具有工业联系的一些工厂往往近距离地聚集起来,形成工业集聚现象。2.工业集聚可获得效应(1)工业集聚可以加强企业间的信息交流和技术协作,降低中间产品的运输费用和能源消耗,进而降低生产成本,提高生产效率和利润,取得规模效益。
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。
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。
(五)平抛运动规律的应用例1:一架老式飞机在高出海面45m的高处,以80m/s的速度水平飞行,为了使飞机上投下的炸弹落在停在海面上的敌船,应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。分析:对于这道题我们可以从以下几个方面来考虑:(1)从水平飞行的飞机上投下的炸弹,做什么运动?为什么?(2)炸弹的这种运动可分解为哪两个什么样的分运动?3)要想使炸弹投到指定的目标处,你认为炸弹落地前在水平方向通过的距离与投弹时飞机离目标的水平距离之间有什么关系?拓展:1、式飞机在高出海面45m的高处,以80m/s的速度水平飞行,尾追一艘以15m/s逃逸的敌船,为了使飞机上投下的炸弹正好击中敌船,应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。2、在一次摩托车跨越壕沟的表演中,摩托车从壕沟的一侧以速度v=40m/s沿水平方向向另一侧,壕沟两侧的高度及宽度如图所示,摩托车可看做质点,不计空气阻力。(1)判断摩托车能否跨越壕沟?请计算说明(2)若能跨过,求落地速度?
3.进一步体会力是产生加速度的原因,并通过牛顿第二定律来理解匀速圆周运动、变速圆周运动及一般曲线运动的各自特点。(三)、情感、态度与价值观1.在实验中,培养学生动手、探究的习惯。2.体会实验的意义,感受成功的快乐,激发学生探究问题的热情、乐于学习的品质。教学重点1.体会牛顿第二定律在向心力上的应用。2.明确向心力的意义、作用、公式及其变形,并经行计算。教学难点1.对向心力的理解及来源的寻找。2.运用向心力、向心加速度的知识解决圆周运动问题。教学过程(一)、 引入新课:复习提问:匀速圆周运动的物体的加速度——向心加速度,它的方向和大小有何特点呢?学生回答后进一步引导:那做匀速圆周运动物体的受力有什么特点呢?是什么力使物体做圆周运动而不沿直线飞出?请同学们先阅读教材
(一)上片:描写杭州的自然风光和都市的繁华“东南形胜,三吴都会,钱塘自古繁华”,“东南形胜”,是从地理条件、自然条件着笔写的。杭州地处东南,地理位置很重要,风景很优美,故曰:“形胜”。“三吴都会”,是从社会条件着笔写的。它是三吴地区的重要都市,那里人众荟萃,财货聚集,故曰:“都会”。“钱塘自古繁华”,这一句是对前两句的总结,因为杭州具有这些特殊条件,所以“自古繁华”。下面就对“形胜”、“都会”和“自古繁华”进行铺叙。“烟柳画桥,风帘翠幕,参差十万人家”是对“三吴都会”的展开描写。“云树绕堤沙。怒涛卷霜雪,天堑无涯”是对“东南形胜”的展开描写。这里选择了钱塘江岸和江潮两种景物来写。“市列珠玑,户盈罗绮,竞豪奢”是对“钱塘自古繁华”的展开描写。描写了两个方面:一是商业贸易情况——“市列珠玑”,只用市场上的珍宝,代表了商业的丰富、商业的繁荣;二是衣着情况——“户盈罗绮”,家家披罗着锦。“竞豪奢”,又总括杭州的种种繁华景象。
最后,公司要城信经营,树立良好的信誉与企业形象。教师活动:引导学生阅读教材P44“金华火腿”的事例;多媒体播放电视系列片3:“小天鹅”重视产品质量的例子,国家对洗衣机的质量标准是4000次运行无故障,而国际标准是5000次,为此,厂里组织近百名科技人员,花了两年时间进行全厂性技术攻关,终于实现了无故障运行5000次。“小天鹅”以它的信誉和质量给企业带来了巨大效益,1000多人的厂子,年销售收入10.03亿元,实现利润1.72亿元,公司跻身于全国500家大型企业的行列,企业综合经济效益居全国18位。设问:两个企业不同命运的原因何在?学生活动:思考讨论,发表见解。教师点评:企业的信誉和形象对企业的生存竞争至关重要,是企业的无形资产,是公司经营成败的重要因素。企业的信誉和形象集中体现在产品和服务的质量上。创立名牌产品,实行优质服务,是企业信誉和形象的表现,也是企业开展正当竞争的主要手段。
材料五航路开辟后,东方香料输入欧洲的总量较中古之时猛增30倍,而胡椒、丁香等在印度购入和在英国卖出的差价亦高达10至29倍,其他货物的获利同样惊人。这一时期,新的商品不断涌现,特别值得注意的是美洲的特产——玉米、马铃薯、烟草、可可等——被传播到欧亚大陆。这时,世界性的对外贸易主要通过大西洋,地中海与意大利皆告衰落,而沿大洋的英、荷等渐居中心。到17世纪时,英国的伦敦与荷兰的阿姆斯特丹成为世界贸易中心。问题4:材料五表明,新航路开辟后对世界贸易产生了哪些重大影响?答案4:结束了世界相对孤立状态;各地文明开始会合交流,日益连成一个整体;欧洲商人直接同世界各地建立商业联系;促进不同国家和贸易的发展,促进世界市场雏形开始出现。
教师总结:社会主义市场经济是使市场在国家宏观调控下起基础性配置作用的经济,充分发挥市场基础性调节作用,就必须主要靠经济手段、法律手段,而不是行政手段。(三)课堂总结、点评这节课我们重点学习了社会主义市场经济的有关知识,知道了社会主义市场经济的基本特征,以及国家宏观调控的含义、目标和主要手段。这对于我们在经济生活中正确地认识我国市场经济的性质和作用,理解国家宏观调控的措施及意义,增强社会主义优越感和民族自强意识,自觉投身现代化建设等将有重大指导作用。★课余作业 讨论:联系经济生活中国家宏观调控的实例,讨论应如何认识和理解国家各种宏观调控手段的综合运用,对国民经济发展的意义。★教学体会 本节内容与学生生活实际联系密切,在学习中应该多引入日常生产、生活中常见的一些宏观调控实例,让学生去深刻理解、把握宏观调控手段及其作用。
