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。

8. However, the more polite you are, the less likely it is you will be attacked. 然而, 你越有礼貌, 你被攻击的可能性就越小。 Step 8 Writing---the articleHow to stay safe in the online chat roomToday I thought I’d blog about a question that has been asked many times--- how do you stay safe online and avoid bad experiences in the online chat room ? I’m not an expert, but many years as a blogger have taught me a thing or two.First of all, there’s the golden rule of the Internet: keep out of what makes you uneasy. Don’t post comments or click on anything. Second, protect your privacy. Don’t give out too much private information like your address, phone numbers, the ID numbers, etc. Third, be polite. If you are polite to others on the Internet, you won’t be attacked in normal situation. Finally, don’t believe in others easily and never meet someone you met online alone. It is very dangerous.Have you had any bad experiences online, or do you have some good advice for staying safe? Post your comments below!Step 9 Pair workExchange drafts with a partner.

Can you find any grammar or spelling mistakes.Step 6 HomeworkPut up your revised draft in the classroom or read it to your class.
小结人们对待祥林嫂这个“嫁而再寡”的不幸女人态度:①、鲁四老爷的态度:不让她干祭祀的活(71、73、75、108通过四婶先后三喊“你放着罢”,杀人不见血地葬送了祥林嫂的性命。而其中尤以最后一次对其打击最大)。鲁四老爷站在顽固维护封建宗法制度的立场上,从精神上残酷地虐杀她。他暗暗地告诫四婶的那段话,就是置祥林嫂于死地而又不露一丝血痕的软刀子。②、鲁四婶的态度:鲁四婶是“大户人家的太太”,头一次留祥林嫂是看她能干,祥林嫂被婆家绑架走以后,她害怕给自己家惹麻烦。之后她惦念祥林嫂不是因为关心她的命运,而是自己的佣人都没有祥林嫂那样可心。以后祥林嫂再来,她“起初还踌蹰”,后来倒是真心怜悯祥林嫂,留下她。但是祥林嫂不像过去那样灵活能干了,四婶开始“不满”,进而“警告”,最后把祥林嫂赶出家门。可以说,四婶只是把祥林嫂当成一件工具罢了,没有把她当人来看。
画中的诸多图像反映了画家对于传统绘画因素的吸收。那个怀抱死去孩子的母亲图像,似乎是源自哀悼基督的圣母像传统;手持油灯的女人,使人联想起自由女神像的造型;那个高举双手仰天惊呼的形象,与戈雅画中爱国者就义的身姿不无相似之处;而那个张臂倒地的士兵形象,则似乎与意大利文艺复兴早期某些战争画中的形象,有着姻亲关系。由此可以看出,毕加索不仅是一位富于叛逆精神的大胆创新者,同时也是一位尊崇和精通传统的艺术家。教师须强调:现代主义美术是现代美术流派的总称,现代美术流派众多,多姿多彩,但它们也表现出许多共同的特征。在技法上,它们大都反对传统的写实主义,追求新奇,空间结构错乱,色彩配置随意,点线紊乱,缺乏透视可谓它们共有的特点。在创作主旨上,它们都主张强调自我,表现个人情感和内心世界。可以说,现代美术艺术再现了20世纪西方世界的精神状况。
3、文化是人们的一种素养(1)人的文化素养是在社会生活、实践中形成的。每个人所具有的文化素养,不是天生的,而是通过对社会生活的体验,特别是通过参与文化生活、接受知识文化教育而逐步培养出来的。文化素养的形成,离不开生活、实践和教育。人们在社会实践中创造和发展文化,也在社会生活中获得和享用文化。(2)人的文化素养表现在日常言行中。教师活动:引导学生阅读教材7页“公交车漫画”材料,并思考所反映的问题学生活动:积极思考并讨论问题教师点评:人们的精神活动离不开物质活动,人们的文化素养总是要通过他在日常生活中的言行、在社会实践活动中的表现等表现出来。我们通过观察人们的社会行为,就可以从中透视人们的精神世界和精神生活。4、文化的传承和发展离不开物质载体。社会文化和精神产品离不开物质载体,一个时代的文化和精神产品,往往是这一时代社会发展轨迹的反映。
另一方面,文化素质影响公民政治权利的行使。随着民主和法制建设的发展,人们为了参与政治生活,需要更高的文化素养。文化水平提高了,人们受到的教育、接受的信息就越多,活动的领域就越广,民主法制和权利意识就越强,这些都会影响人们的民主素质和民主水平,使人们更好地进行政治参与,行使民主权利。(2)文化与国际政治相互交融,成为当代国际政治斗争的重要内容。随着世界多极化的发展,奉行霸权主义的国家,借助文化渗透的方式,竭力推销自己的价值观念,企图削弱和取代别国的民族文化,以推行强权政治。这使世界范围内反对文化霸权主义的斗争,成为当代国际政治斗争的重要内容。文化已经成为进行政治斗争、国际斗争的重要形式之一。对文化市场的争夺不仅仅是争夺票房价值、争夺经济效益,更主要的是对受众对象的争夺,对受众注意力这种特殊的稀缺资源的占有,以及在此基础上对舆论的控制与引导。因此,失去文化市场就意味着失去政治优势,意味着政治影响力的边缘化乃至萎缩或丧失。这一点,从目前世界正在进行的空前规模的“文化战争”,可以看得非常清楚。
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。
一、教材内容经全国中小学教材审定委员会2004年初审查通过,人教育出版社出版的普通高中课程标准实验教科书《物理必修①》,第三章第5节内容“力的分解”。二、教学目标1.知识与技能(1)理解分力的概念,理解力的分解是力的合成的逆运算,遵循平行四边形定则。(2)初步掌握一般情况下力的分解要根据实际需要来确定分力的方向。(3)会用作图法和直角三角形的知识求分力。(4)能区别矢量和标量,知道三角形定则,了解三角形定则与平行四边形定则的实质是一样的。2.过程与方法(1)进一步领会“等效替代”的思想方法。(2)通过探究尝试发现问题、探索问题、解决问题能力。(3)掌握应用数学知识解决物理问题的能力。3.情感态度与价值观(1)通过猜测与探究享受成功的快乐。(2)感受物理就在身边,有将物理知识应用于生活和生产实验的意识。三、教学重点、难点在具体问题中如何根据力的实际作用效果和平行四边形定则进行力的分解。
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。
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
(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?
全班齐读第五段内容。请一位同学分析,接着让这位同学按他分析的读一遍。3、4两自然段的平缓之后,第5段作者的情感再次抬升。为了满足这种情感的张扬,作一口气连用了四个排比句式“现在是……时候”,一方面这是情感发泄的需要,另一方面这种排山倒海的语势也加强了内容的表达,极强地突出了现实为自由、平等而战的重要性。四、学会演讲我们刚才细读了课文,但读和讲是有区别的。所谓演讲,是一门语言艺术,它的主要形式是“讲”,即运用有声语言并追求言辞的表现力和声音的感染力;同时还要辅之以“演”,即运用面部表情、手势动作、身体姿态乃至一切可以理解的态势语言,使讲话“艺术化”起来,从而产生一种非凡的艺术魅力。那么,接下来就假设一下假如你是马丁·路德·金,你会怎样去讲这篇演讲辞。
The theme of the reading and thinking is about “Understanding how a problem was solved”.The Listening & Speaking & Talking is about international co-work to protect the Mount Tai, in which the students from seven countries came up with many solutions even create the Mount Tai App. This section aims at showing how to solve a difficult and even tough problem about protecting the cultural heritage by the international co-work. So in this section, cultivating students’ international awareness is very clear and important. Concretely, with the economic development, how to balance the protection of cultural relics and social development is a big challenge for human. In the 1950s, the Egyptian government wanted to build the Aswan Dam across the Nile to control floods, produce electricity and water farms. But the proposal led to protests because it would destroy a lot of cultural relics. The Egyptian had no choice but ask the UN for help. Therefore, a international cooperation about how to protect the cultural relics began, which involved the time length about 20 years and a large amount of fund. Then, the problems was solved. 1.

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?
