Teaching procedures I’m sure there are more than two! Now who’d like to give the answer to the third question?

S4: Let me try, Sir / Madam. I’ll try to use body language to tell the other what I need urgently. I’ll do it by miming, by any proper posture, or gestures, even by drawing pictures.

T: You are smart! Now who’d like to do the last one. It is more challenging, right?

S5: I’d like to have a try, sir. Last summer I went on a study tour in the States. When I was on the way to

Los Angeles on the flight of the United Airlines, we stopped at Tokyo / Narita Airport in Japan for 3 hours. So I went into the shop at the airport, for I wanted to buy a digital camera. Of course I knew no Japanese, so I spoke to her in Chinese first and then in English. It seemed that she was at a loss when I spoke to her. Then I decided to try it in body language. I just pointed to the camera that I like most-Sony Cyber-shot DSC-p100. The salesgirl spoke to me in Japanese this time but I couldn’t understand a word of it. So I shook my head and kept pointing at the camera. Finally I reached her understanding and she took out the camera I wanted to buy. I examined it for a little while and asked her the price of it by drawing a big “?” in the air with my forefinger. She took out her calculator and put in the price. The price was reasonable and I decided to take it. I paid for it and the salesgirl bowed to me again and again.

T: Wonderful! Thank you for telling us so interesting a true story and giving us so good an example of body language.

Step Ⅲ While-reading

1. Scanning

While reading, please try to pide the whole passage into several parts and find out the main idea.

part 1 para 1

You are sent to Capital International Airport to meet this year’s international students.

part 2 (para. 2 and 3 )

Examples of learned or cultural “body language”.

part 3. (para. 4 )

Different peoples have different body languages.

part 4. (para. 5)

Summary of body language.

Read the text carefully, then decide if the following statements are true (T) or false (F).

Englishmen often stand close to others or touch strangers as soon as they meet.

Most people around the world now greet each other by kissing .

Japanese will bow to others as greeting.

people from Jordan will move very close to you as you introduce yourself to them.

Some body languages in some countries are good while some countries’ body language are bad.

Step IV post reading

1. Is the author of this passage male or female? How do you know ?

The author is male. Ahmed Aziz will not shake hands with women, but he shakes hands with the author.

2.What were the two mistakes that the author noticed?

He noticed that the Colombian man kissed the British woman, but in her culture, a kiss from a stranger is not acceptable. He also noticed that the Japanese man bowed just as the Canadian man started to shake hands, so one man’s nose touched the other man’s hand.

3. Who seemed to prefer to keep more physical distance from others? Who seemed to prefer closer physical distance ?

The British woman, Julia, and probably the Canadian man, George, seemed to prefer to keep more physical distance from others. The Colombian man, Tony, and the Jordanian man, Ahmed, seemed to prefer closer physical distance .

4. Did any students have similar greeting customs? If so, which ones?

Yes. Tony from Colombia and Darlene from France had a similar greeting custom-a kiss. George from Canada and Ahmed from Jordan also had a similar greeting custom-a handshake, but Ahmed shakes hands only with men.

5. “ When in Rome, do as the Romans do.” What do you think this famous saying means?

This saying means that when we are in a certain place, we should follow the customs of the people who live in that place, not our own customs.

6. Do you agree with the author’s statement that body language is not good or bad? Why or why not?

Students will give their own answers.

Step Ⅴ Homework

1. Get ready to retell the text in your own words.

Background Information

CHARLIE CHApLIN

Charlie Chaplin,who died in 1977,is considered one of the greatest and funniest actors in the history of the cinema.During his lifetime,he acted in 13 films,and he wrote,directed and acted in 69 other films.

Chaplin was born in London in 1889 and first acted when he was five years old.At the age of eight,he joined a group of child dancers,and at seventeen he set off to the USA with a group of comedy actors.During a second trip to the USA in 1912,an important film director saw Chaplin acting a very funny part in a play.As a result,Chaplin got his first film part in the States.

As early as his second film,Chaplin had developed his own manner of acting,the one that was to become world-famous.He wore a small black hat,very wide trousers,a moustache and carried a stick that he swung in the air as he walked.Even his way of walking down the street and turning a corner could be recognized as his own.In less than three months Chaplin acted in 11 films.In a short while he started directing films himself.During his first year,Chaplin acted in 35 films,many of which he wrote and directed himself.

Chaplin's earliest films were silent films,because the equipment for adding sound to films had not yet been developed.The development of films with sound became a problem for Chaplin,as he was uncertain about making films with dialogue.Instead,he continued to make films without dialogue,but he added music,which he wrote himself.Two of his greatest films,"City Lights" and "Modern Times" were of this kind.

Chaplin's later films,however,were not well received.He made only six films between 1940 and 1966 and only the first of these is still popular today.Chaplin lived the last years of his life in Switzerland,where he was buried in 1977.Before he died,he was honoured in a number of ways for his contributions to the film industry.

One of Charlie Chaplin's most famous films was "The Gold Rush",which was made in 1925.The film was set in California in the middle of the nineteenth century.At that time,gold was discovered in California and thousands of people rushed there to look for gold,so it became known as "the gold rush".people said gold could easily be picked up by washing sand from the river in a pan of water.This was known as "panning for gold".

In the film,Chaplin and his friend are in California.So far,they have been unlucky in their search for gold and have no money at all.Chaplin and his friend are caught on the edge of a mountain in a snow storm in a small wooden house.They have nothing to eat.They are so hungry that they cook a pair of shoes,by boiling them,in a pan of water.Chaplin sits down at the table and eats the shoe with a knife and fork,enjoying every mouthful.He makes it seem as if this is one of the most delicious meals that he has ever enjoyed.

【教学重难点】

重点:孝文帝改革对政权封建化进程的作用。

难点:孝文帝改革对民族融合和国家统一的历史意义。

【教学建议】

本课教材从三个方面向学生介绍了孝文帝改革后的影响:经济的复苏和繁荣,政权封建化,民族的交流与融合。这三个方面不是孤立的而是相互联系的:孝文帝改革推行均田制、三长制及租调制,把农民与土地紧密结合起来,使鲜卑的牧民转化为农民,扩大和巩固了自耕农队伍,经济得到了恢复与发展,促进了民族融合。生产、生活方式的变化推动了鲜卑族统治者接受汉族先进文化与制度,如兴儒学、恢复汉族礼乐制度、定官制、修律令等,大大加速了政权封建化进程。孝文帝移风易俗的改革和经济、政治的变化又使鲜卑族等少数民族与汉族交往密切、交流频繁,风俗习惯逐渐趋同化,汉族的风俗习惯成为整个社会风俗习惯的主体,同时鲜卑族原有的文化精华也融入汉族文化之中。建议教师通过探究问题、分析图片和课堂讨论的形式让学生认识这三方面的相互关系,把握本课的中心和线索,进而高屋建瓴地认识到中华民族是多民族的统一体,民族融合是中华民族形成的重要过程,孝文帝改革是促进民族大融合的一项力措,使学生体会到孝文帝是一位杰出的少数民族政治家、改革家,加强了这堂课的思想性。

二、教学过程:

新课导入:

利用教材中的引言导入新课:

教师先出示山西大同云冈石窟和河南龙门石窟的两幅佛像图片。

师:通过这些图片,你从中获得哪些历史信息?

生1:北魏佛教文化的兴盛。

生2:北魏石窟艺术的发展。

生3:孝文帝改革前后佛像的迥异。……

师:这些作品的艺术风格有何不同?说明了什么问题?

生1:云冈石窟的佛像主要是北魏时期开凿的,这些雕像共同的特征是:面相丰满,目大眉长,鼻梁高隆,直通额际,口唇较薄,嘴角微微上翘,呈微笑之意,肩宽胸挺,躯肢浑厚健壮,神态温静具有伟丈夫的气概。体貌表现了少数民族的特征。

生2:龙门石窟的佛教造像面容清瘦,褒衣博带,性格爽朗,风神飘逸,从侧面反映了孝文帝孝文帝迁都后,大力推行汉化,带有明显的汉族文化的特征。

师:对,从上面两幅佛像造型看出,北魏孝文帝改革前后所发生的重大变化。那么,除了服饰变化外,孝文帝的改革还引起了哪些方面的变化呢?由此导入新课。

讲授新课

北魏孝文帝改革的主要影响

(一)经济的复苏和繁荣:

1、农牧业的发展:

(1)表现:

①生产工具的改进:整地碎土工具的复杂化与精耕细作;

②耕作技术的提高:“宁可少好,不可多恶”,“顷不比亩善”;

③重视兴修水利:有水田之处通渠灌溉;

④经济作物和畜牧业的发展;

⑤荒地得到更多地开垦,粮食产量提高,人口增殖。

(2)原因:

①政府政策的调整即孝文帝改革推行的均田制、三长制和租调制;

②民族大融合的影响;

③农业生产力的发展包括生产工具的改进,耕作技术的进步,水利设施的兴修等

2、手工业的成就:

(1)表现:

①丝织业发展达到魏晋以来的水平:绢布产量大增,府存绢帛多;

②制瓷业的发展对唐宋时期北方瓷器的繁盛有直接影响:

北魏迁都洛阳以后,制瓷业又发展起来。北方青瓷在造型、胎釉、纹饰等方面与南方不同,一般器型较大,以尊、瓶、罐、钵之类居多。胎体厚重,胎色灰白,釉较厚,玻璃质强,流动性大,器表往往有玻璃质流珠现象。器物多以莲花瓣纹、忍冬纹作装饰,装饰方法有堆贴、模印、刻划多种。北方青瓷的莲花纹饰与佛教的盛行关系密切。

(2)原因:农业、商业的发展,孝文帝的扶持政策。

3、商业活动的活跃:

(1)表现:

①洛阳大市场的繁荣:设有专门管理贸易和税收的官吏;货源充足、交易活跃,商人实力雄厚。如市场上金银、锦绣、瓷器、漆器等,应有尽有;全城十多万户居民中,有上万户来自各地的商人,其中包括来自远方异国的商人。

②重新铸造铜钱;

③对外贸易有长足发展:与朝鲜半岛诸国、日本以及地中海沿岸国家都有贸易往来。

(2)原因:农业和手工业的发展;孝文帝铸造铜钱,重视和支持商业。

(二)政权封建化的加速:

1、措施:

①尊儒崇经,兴办学校:孝文帝从小熟读儒家经典,建孔庙并亲自祭拜,起用儒家人士,兴办太学,教授儒家经典,培养人才。儒家文化是汉文化的主体,儒学既重外在的行为规范又重内在道德的自律,维护了封建统治和社会秩序的稳定。

②恢复汉族礼乐制度:所谓礼乐制度是周代最早对“礼”(祭祀、朝食等仪式)和“乐”(伴随“礼”进行的乐舞)作出规定的制度,是对宗法制和等级制的强调和固定。孔子对礼乐制度加以系统的理论说明,提出“仁”的理念,高扬仁爱与和谐的思想,用以提升和深化已有的礼乐文化,使礼乐文化进一步成为礼仪文化,历代统治者沿用这一制度来维护统治。孝文帝制定各种礼仪制度,废置鲜卑族的祭祀礼仪,改用汉族的祭祀礼仪,加速了政权的封建化,最终维护鲜卑族的统治。③采纳汉族封建统治制度:孝文帝仿汉官制,制定北魏官制。修律令,废除一些带有奴隶制成份的落后残酷的法律,保证了汉化政策与制度的施行。

2、影响:北魏统治者接受了汉族先进文化与制度,大大加速了北魏政权的封建化进程,对北魏的政治生活乃至整个中国历史产生了深远影响。

(三)民族的交流与融合:

1、表现:

(1)生活习惯的汉化:即三个变化——

①鲜卑族经济方式的变化:鲜卑族筑起简陋的房舍,经营小块土地,最终脱离了游牧生活和部落联系,开始转向中原汉族的农业文明。

②鲜卑族的阶级成分的变化:迁居洛阳的鲜卑族劳动者陆续成为中原的农民,贵族占领良田成为中原的封建地主,有的还兼事工商业。

③生活习惯也发生变化:汉族风俗习惯成为整个封建社会风俗习惯的主体。

(2)鲜卑族优秀文化的融入:

①鲜卑族畜牧业生产经验的融入:如北魏贾思勰写的《齐民要术》,总结了北方先进的农牧业生产经验,对北方的经济生产起着一定的影响。

②服饰与风俗的融入:如诗歌描写汉族女子“褰裙逐马如卷蓬,左射右射必叠双”。

③食物的融入:如教材插图《汉人胡食画像砖》就是明证。

2、影响:北魏孝文帝改革缓和了民族矛盾,巩固了封建统治,更促进了民族的大融合,为结束长期分裂局面,重新走向国家统一奠定了基础。

【合作探究】今天我们吃着烤羊肉串,徜徉在云冈石窟中,遥想当年鲜卑人叱咤风云、横扫天下的气势,他们作为单一的民族消失了,从这个角度上说孝文帝或许被称为历史的罪人,但孝文帝的改革顺应了民族融合的大趋势,推动以鲜卑族为中心的北方少数民族的汉化进程,为中华民族注入了新鲜血液,鲜卑族及鲜卑文明在一个民族大家庭里也得到了永生。我们又谁能说得清自己身上是否流淌着鲜卑族人的血液?中华民族千百年来的凝聚力就是来自于历无数次的民族融合。

请大家结合孝文帝改革的三节内容,分析孝文帝改革成功的原因是什么?对我们今天的改革有何启示?谈谈你对孝文帝改革的评价。

提示:

成功的原因:

①改革顺应了时代潮流;

②符合民族融合趋势和各族人民的愿望;

③符合统治者巩固统治的需要;

④孝文帝的胆略和卓越见识,冲破阻力,毅然改革。

认识:

①先进必然战胜落后;

②改革必须符合历史潮流、顺应民意;

③任何改革都不是一帆风顺;

④民族融合与孝文帝改革互为因果关系的。

评价:

孝文帝改革促进了北方经济的复苏和繁荣,加强了民族大融合,为国家结束分裂、走向统一和封建社会的繁荣奠定了基础。孝文帝是我国少数民族中杰出的政治家、改革家,是中华民族的千古功臣。

教学小结:

北魏孝文帝在阶级矛盾和民族矛盾尖锐的情况下积极地、主动地、彻底地进行了一系列改革,这场改革是由冯太后和孝文帝自上而下掀起的一次改变北魏社会面貌的封建化改革运动,它使鲜卑族发生了根本性的变化:社会制度封建化、生产方式农业化、风俗习惯汉族化,从而有利于北方经济的发展,缓和了民族矛盾,巩固了封建统治,加强了民族大融合,为国家结束分裂、走向统一和封建社会的繁荣奠定了基础。孝文帝是我国少数民族中杰出的政治家、改革家,是中华民族的千古功臣。

三、问题解答:

学思之窗:

北魏的贵族大都经商的事实,说明了什么问题?

参考答案提示:北魏商业繁荣,商品经济深入人心;鲜卑族逐渐汉化。

本课测评:

1、北魏孝文帝实施改革后,北魏的社会经济出现了哪些变化?这些变化对北魏社会历史的发展又具有什么样的影响?

参考答案提示:社会经济的变化

农业:荒地得到开垦,粮食产量提高,人口增加,耕作技术提高,畜牧业发达。

手工业活跃:民间和官办手工业发展快,绢布产量增加且工艺精湛,北方青瓷出现。

商业活动活跃:洛阳出现许多大市场,货源充足,交易活跃,对外贸易远达西方国家。

影响:经济的变化推动了鲜卑族的游牧经济向农耕经济的转型,增加了国家收入;经济的变化促使孝文帝进一步接受汉族先进文化与制度,加速政权的封建化进程,巩固了封建统治;经济的变化促进了民族大融合,使鲜卑族等少数民族成为汉族一部分,为中华民族注入了新鲜血液。

2、为什么说孝文帝改革的最重要历史意义在于它促进了中国北方地区的民族大融合,并为隋唐时期国家重新实现统一奠定了基础?

参考答案提示:孝文帝改革是在民族矛盾和社会矛盾尖锐的情况下为发展生产,巩固统治而进行的自上而下的改革。经济上推行均田制和租调制,农业成为经济的主要成分,使游牧为主的鲜卑族变为农民,促进了经济的复苏与繁荣;政治上迁都、实行官吏俸禄制,整顿吏治,设立三长制,采纳汉族封建统治制度,这些措施加强了国家管理,巩固了统治,团结了汉族地主,有力地推动了政权的“汉化”。文化和风俗习惯上全面接受汉族先进文化,移风易俗。这些措施促进了鲜卑族人对汉族文化的认同,加强了民族的交流与融合。孝文帝改革使鲜卑族最终融于汉族之中,有力地推动了中华民族的形成与发展。同时,南北之间民族隔阂的消除,北方经济的繁荣,为隋唐时期国家的重新统一奠定了基础。

学习延伸:

1、(略)

2、争鸣:

对孝文帝改革的意义,学术界基本持肯定态度,但也不乏不同声音。499年孝文帝去世后,北魏即进入内部动乱不已的多事之秋,二十余年之后,爆发了六镇起义,再过十余年,北魏分裂为东魏、西魏二国,实权分别落入高欢、宇文泰之手。因此,有学者认为造成北魏后来局面的根源,实际上可以追溯到孝文帝改革。因为,孝文帝舍平城迁洛阳,改鲜卑武勇之风为汉人文弱之风,进一步削弱北魏军事力量,这是他终不能强大魏国的重要原因。并说孝文帝的改革,学来的主要是汉人的繁文缛节,丢掉的恰恰是拓拔的长处——勇武质朴,这就加速了北魏的衰亡。

你同意上述见解吗?谈谈你的看法。

答(1)同意。在孝文帝统治期间,他通过 改革,学习汉人的生产和生活方式,用汉人的文化改造了鲜卑族,这些措施使鲜卑族丢弃了本民族的特色,导致了鲜卑族军事力量的衰退和统治力量的削弱,加速了北魏的衰亡。

(2)不同意。迁都洛阳后,鲜卑族在孝文帝改革的推动下,其统治者接受了汉族先进的文化与制度,大大加速了北魏政权封建化的进程,促进了北方经济的恢复和发展,更为重要的是改革促进了北方民族的大融合,为隋唐时期结束长期分裂局面,重新走向国家统一奠定了基础。因此,对孝文帝改革应充分肯定, 孝文帝是我国历杰出的少数民族政治家、改革家。

单元学习小结

一、重要概念简释

【均田制】

北魏时期实行的国有和私有相结合的封建土地制度。主要内容是国家把荒地分给丁男露田40亩,妇女20亩;丁男受桑田20亩。露田在农民60岁免课赋或身死时归还政府;桑田传给子孙。地主按级别也分给公田。均田制的实行,把农民与土地结合起来,在一定程度上抑制了土地兼并,调动了农民积极性,有利于农业的发展和社会的稳定。同时推动着鲜卑族经济的转型,加强了民族大融合。

【三长制】

北魏的基层行政组织制度。为配合均田制的实行,北魏统治者规定:五家立一邻长;五邻设一里长;五里设一党长。它的职责是检查户口,征收赋税,征发徭役和兵役,推行均田制。它的推行,健全了县以下的地方基层政权,完善了国家从中央到地方的行政体制,保证了国家对人民的控制,巩固了北魏的统治。

【“汉化”措施】

北魏统治者实行的推动鲜卑族向汉族同化的措施。孝文帝基于对汉族先进文化优越性的认识和巩固统治的需要出发而自觉主动地实行的一系列改革措施。通过这些措施,从生产、社会制度、风俗习惯等全面接受汉族文化,大大促进了民族融合,为结束南北分裂奠定了基础。促进了中华民族的形成与发展。

【迁都洛阳】

为加强对中原地区的统治,减少改革的阻力,孝文帝决定把首都从经济落后、地理环境偏远的平城迁往中原的政治经济文化中心洛阳。孝文帝克服阻力,设巧计迁都。迁都洛阳,为孝文帝进一步的改革奠定了基础。

二、归纳与总结

【单元内容小结】

5世纪,北魏统一了黄河流域。当时民族矛盾和阶级矛盾尖锐,统治者面临着严重的统治危机。为缓和民族矛盾,发展生产,巩固统治。基于对汉族文化优越性的认识,北魏统治者孝文帝自觉地、主动地进行了大刀阔斧的改革。主要内容为实行官吏俸禄制、均田制、三长制;恢复汉族礼乐制度,采纳汉族封建统治制度;迁都洛阳,移风易俗;尊儒崇经等。改革推动了北方经济的复苏与繁荣;争取到了汉族地主阶级的合作与拥护,巩固了北魏的统治;改革使鲜卑族全面汉化,消除了民族隔阂,推动了鲜卑族为中心的北方少数民族的大融合,为国家重新统一奠定了基础。同时,鲜卑族等少数民族的文化精华也融入汉文化中,为隋唐封建社会的繁荣创造了条件,推动了中华民族的发展。

第二课时:学生分组实验:乙醛的银镜反应、乙醛与新制氢氧化铜反应;简单介绍酮的性质。
第三课时:《步步高》 醛的练习讲评。
第四课时:《步步高》 酮的练习讲评
2、教学目标:
认识醛类的结构特点和性质主要通过醛类的典型代表物──乙醛,介绍了乙醛的氧化反应和加成反应,主要通过实验来归纳乙醛的性质;结合乙醛的结构特点,复习和应用核磁共振氢谱图;结合乙醛的加成反应,进一步认识有机化学中的氧化反应和还原反应。
教学重点:乙醛的结构特点和主 要化学性 质。
教学难点:乙醛与银氨溶液、新制cu(oh)2反应的化学方程式的正确书写。
3、资料准备:
选修5《有机化学基础》教材、《步步高》、实验药品、仪器、视频
4、新课授课方式(含疑难点的突破):
第一课时 醛
学生已经掌握了乙醇的结构和性质,掌握了羟基官能团的结构特点及其在化学反应中可能的变化,因此教学的重点是帮助学生在对比羟基和醛基官能团结构的基础上,运用“结构决定性质”的观点,推测乙醛 可能的化学性质;再通过实验,探究乙醛的化学性质,落实“性质反映结构”的观点;最后通过小结醛基的结构和性质,帮助学生迁移到醛类化合物,并掌握醛基发生氧化、还原反应的基本规律。
根据“结构决定性质”的观点,首先提示讨论乙醛的结构特点,推测乙醛可能的化学性质,

然后开展实验探究,探 究乙醛的还原性。探究乙醛与高锰酸钾酸性溶液、与银氨溶液、与cu(oh)2反应的实验现象和反应规律。讨论小结实验现象,书写反应的化学方程式。

讨论学习:边讲、边讨论乙醛与银氨溶液、新制cu(oh)2反应的化学方程式的书写。

讨论反应规律,1 mol 醛基(—cho)可还原2 mol ag+或2 mol cu(oh)2,醛基(—cho)转化为羧基(—cooh)。
迁移提高:根据乙醛与 银氨溶液、新制cu(oh)2反应的规律,写出甲醛、丙醛与银氨溶液、新制cu(oh)2反应的化学方程式。
讨论题:下列有机物中,不能发生银镜反应的是()。
a.hcho b.ch3ch2cho c.hoch2ch2oh d.ch3cooh
答案:c、d
小结:乙醛的反应中“官能团转化”的基本规律:

第二课时 学生分组实验
【实验3-5】乙醛的银镜反应
实验关键:为使生成的银能很好地附着在试管壁上,可先在试管中加入naoh溶液,加热煮沸1 min,以除去试管壁上的油污;硝酸银溶液要新配制 的,若放置太 久或酸性太强实验效果都不佳;氨水要稍过量一点,保证反应在弱碱性条件下进行。配制银氨溶液时,向硝酸银溶液中滴加氨水的过程中,应先产生白色略带棕色的沉淀,然后再继续滴加氨水使沉淀溶解;若溶液始终澄清,则说明药品的浓度、用量有问题,或试剂放置太久不宜再用。
【实验3-6】乙醛与新制氢氧化铜反应
实验关键:乙醛与新制cu(oh)2的反应,需要在较强的碱性条件下进行。因此,naoh要大大过量于cuso4。试剂要用新制的cu(oh)2,否则cu(oh)2悬浊液会吸收空气中的co2转化为碱式碳酸铜而影响实验效果。
