教学目标:1、知识与能力:①了解荆轲刺秦王的历史背景和过程,整体感知课文。②掌握文言文中重要的字、词、句解释,提高翻译能力。③学会从人物的对话、动作、神态描写入手,分析主要人物形象。2、情感与态度:正确看待荆轲刺秦王这一事件,学会历史而辩证地评价人物。重点难点:评价历史事件,分析人物形象。教学方法:朗读法、提问法、讨论法课时安排:三课时教学过程:第一课时一、导入:(课前展示雕塑照片)来到正定讲课,我感到非常高兴,一进县城,就被这里浓郁的历史文化气息所感染。我们住在华阳假日酒店,外面正在兴建文化广场,刚才的照片就是在那里拍摄的。在此,我进一步了解到正定这座文化古城悠久的历史渊源,这里有南越王赵佗,常胜将军赵云,一代名家颜真卿等等,可谓物华天宝、人杰地灵。因此我相信我们正定中学的同学们一定都非常优秀。这也让我更深刻地体会到一个道理:语文的外延就是生活的外延。
【教学意图】要了解中国传统文化,必须阅读古诗文名著名篇。但在中国文化形成过程中影响最大的是什么?可以说是儒家学说,包括《论语》这部经典。《论语》等书是读书人求仕做官的必修课本,是知识分子的思想言行基础,而且影响到整个社会生活,内容包括伦理道德、教育体制、民间习俗等方面的思想。因此,要了解中国传统文化,有必要读一读《论语》。【教学设计】因《论语》的年代已久远,对学生而言,要理解透彻文句是比较深奥困难的,因此必须在充分理解文意的基础上,对《论语》进行思想上的解读。可由教师从《论语》中概括出几点与生活、现实相关的要点,要求学生分组进行透彻的学习和领会,如“小人与君子”、“学习的方法”、“教育的理念”等等。〖教学重点、难点〗读《论语》知儒家思想。〖教学方法〗讲解启发、探究梳理、拓展延伸。
①从政府人员组成看,南京政府是一个以资产阶级革命派为主体的政府。②从政府颁发的法令和措施看,这些法令体现了资产阶级民主革命的要求,对于发展民族资本主义经济、资产阶级民主政治和文化教育以及改革社会风气,都起了积极作用。③从颁布的《中华民国临时约法》看,宪法体现了三权分立的政治体制,体现了资产阶级民主主义的要求,是中国历史上第一部资产阶级民主宪法,具有反封建专制制度的进步意义。(2)从南京临时政府的内外政策分析南京政府的根本弱点①未彻底地反封建。它没有采取比较彻底的反对封建主义的措施,特别是对封建统治的基础——地主阶级土地所有制没有触动,这样,南京临时政府也就不能真正地把广大人民群众动员起来,因而缺乏真正的群众基础。
【备课资料】百团大战八路军从8月20日起,在华北敌后出动105个团,约40万兵力,在2500公里长的战线上,发动了规模最大的“以彻底破坏正太路若干要隘,消灭部分敌人截断该线交通”为目的的举世闻名的“百团大战”。八路军提出“不留一根铁轨、不留一根枕木、不留一个车站、不留一个碉堡、不留一座桥梁”的口号,“让敌人用脚同我们赛跑”,“让敌人用牛驴搬炮弹、飞机大炮”。八路军展开攻坚战,端掉敌一系列据点。据有关资料记载,从8月20日到12月5日,在历时三个半月的“百四大战”中,我军共进行大小战斗1824次,毙伤日伪军25800余人,俘日伪军18600余人,缴获了大批武器、弹药和军用食品等;破坏铁路470多公里,公路1500多公里,桥梁、车站、隧道等260余处,使正太铁路停运月余;攻克日伪据点2993个,巩固和扩大了抗日军民占领区。

This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本节语法思考:定语从句在复合句中的作用是什么? 关系词有哪些?定语从句在复合句中的作用相当于形容词,它在句中作定语修饰名词或代词。他们在先行词和定语从句之间起到联系作用,同时在意义上代表先行词并在定语从句中担任一个成分。被定语从句所修饰的词称先行词,定语从句一般放在先行词的后面。
1. This section focuses on "Understanding how a problem was solved”, which is aimed to guide students to analyze and discuss the challenges and problems faced by cultural heritage protection during the construction of Aswan Dam, as well as the solutions. On the basis of understanding, students should pay attention to the key role of international cooperation in solving problems, and attach importance to the balance and coordination between cultural heritage protection and social and economic development. Students are encouraged to face challenges actively, be good at cooperation, and make continuous efforts to find reasonable ways and means to solve problems.2. Enable students to understand the main information and text structure of the reading text;3. Motivate students to use the reading strategy "make a timeline" according to the appropriate text genre;4. Enable students to understand how a problem was solved;5. Enable students to understand the value of protecting cultural heritage by teamwork and global community;1. Guide students to pay attention to reading strategies, such as prediction, self-questioning and scanning.2. Help students sort out the topic language about protecting cultural relics and understand the narrative characteristics of "time-event" in illustrative style3. Lead students to understand the value of protecting cultural heritage by teamwork and global community;
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.

③于是,大自然出现了惊人的奇迹,不毛的石缝间丛生出倔强的生命。④或者就只是一簇一簇无名的野草,春绿秋黄。岁岁枯荣。它们只有三两片长长的细瘦的薄叶,那细微的叶脉,告知你生存该是多么艰难;更有的。它们就在一簇一簇瘦叶下自己生长出根须,只为了少向母体吮吸一点乳汁,便自去寻找那不易被觉察到的石缝。这就是生命,如果这是一种本能,那么它正说明生命的本能是多么尊贵,生命有权自认为辉煌壮丽,生机竟是这样地不可扼制。⑤或者就是一团一团小小的山花,大多又都是那苦苦的蒲公英。它们不似田野上的同宗长得那样茁壮,它们的茎显得坚韧而苍老。它们的叶因枯萎而失却光泽。它们已经不能再去为人们作佐餐的鲜嫩的野菜,却默默地为攀登山路的人准备了一个可靠的抓手。生命就这样地被环境规定着,又被环境改变着,适者生存的规律尽管无情。但一切适者就是战胜环境的强者。生命现象告诉你,生命就是拼搏。
材料四:印度提倡“只生一个好”——鼓励三人小家庭 生男生女都一样材料五:印度尼西亚《人口发展与幸福家庭法》材料六:我国基本国策 计划生育(小结)通过对以上材料的分析我们可以得出这样的结论,不同的国家应该采取不同的人口政策,对与发达国家来说人口增长缓慢,应采取鼓励生育,吸引移民的措施;发展中国家人口增长较快,实行控制人口的政策已经迫在眉睫。不论是发达国家还是发展中国家共同的目标就是实现环境人口和社会经济的协调发展。【课堂小结】这节课我们主要学习了人口的自然增长,影响人口自然增长的因素有哪些?(人口的自然增长率和人口的基数)世界人口的数量在不同的历史时期表现出不同的特征,同一历史时期的不同地区,人口数量的增长又有不同的特点。面对不同的人口形势,各国应采取不同的人口政策。
1.促使美国成为一个移民国家的因素是:①美洲属于未开发的新大陆,需要大量的劳动力;②欧洲失业工人和破产农民增加,人们为了追求更好的经济待遇迁往美洲;③新航线的开辟为人们顺利迁移扫除了障碍;④殖民扩张是人口迁移的促进因素,加快了人口迁移的过程。导致美国人口在本土范围内频繁迁移的原因,归纳起来有:第一次人口迁移是战争因素,第二次是城市化;第三次是自然环境、经济环境的变化;第四次是经济格局的变化,即西部和南部新资源的发现和新兴工业的发展。2.我国古代的人口迁移,深受统治者及其行政力量的束缚。封建帝王为了加强本国的经济和军事实力,对人口迁移严加控制。只有当战乱发生的时候,这种控制才得到削弱,人们为了躲避战乱,寻找安定的生活环境,不得不进行大规模的迁移。我国近几十年的人口迁移主要是由生产资料和劳动力数量上的地区分布不平衡造成的,是经济因素在起主导作用,与古代的人口迁移截然不同。
在经济水平较高、工业地域规模较大的地区,其发展潜力就远不一样,如钢铁工业。钢铁工业的生产过程比较复杂(如课本图5.31),需要有相互接近的工厂,不仅包括从事钢铁生产各道工序的工厂,如烧结厂、焦化厂、炼铁厂、炼钢厂、轧钢厂,还包括与钢铁生产有联系的工厂,如氧气厂、机修厂、发电厂、水泥厂等,总共可达20~30个工厂。这些工厂集 聚,设备大,管线长,占地多。因此,这样形成的工业地域(钢铁工业区)面积广,发育程度高,发展潜力大。这类工业地域 再加上为方便众多工人生活所配置的服务业和其他工业,在发展过程中,往往由于工业地域的扩展而形成工业城市。例如,我国的鞍山(“钢都”)、攀枝花、马鞍山、包头(“草原钢城”)等钢铁工业城市的形成。除此之外,石油化工区、机械制造工业区等属于发育程度高的工业地域,也往往扩展而形成工业城市。例如,我国的石油城大庆、克拉玛依,汽车城十堰等。
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。
(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
猜想:既然物体下落过程中的运动情况与物体质量无关,那么为什么在现实生活中,不同物体的落体运动,下落快慢不同呢?我们能否猜想是由于空气阻力的作用造成的呢?如果没有空气阻力将会怎样呢?学生讨论后回答.三、猜想与假说伽利略认为,自由落体是一种最简单的变速运动.他设想,最简单的变速运动的速度应该是均匀变化的.但是,速度的变化怎样才算均匀呢?他考虑了两种可能:一种是速度的变化对时间来说是均匀的,即经过相等的时间,速度的变化相等;另一种是速度的变化对位移来说是均匀的,即经过相等的位移,速度的变化相等.伽利略假设第一种方式最简单,并把这种运动叫做匀变速运动.四、实验验证实验验证是检验理论正确与否的唯一标准.任何结论和猜想都必须经过实验验证,否则不成理论.猜想或假说只有通过验证才会成为理论.所谓实验验证就是任何人,在理论条件下去操作都能到得实验结果,它具有任意性,但不是无条件的,实验是在一定条件下的验证,而与实际有区别.
