2.to learn some words of describing friend and friendship 3.to master some useful words and expressions Teaching methods: 1.discussing
2.cooperative learning
Teaching materials: Warming up Teaching procedures: Step One: Leading-in 1.Free talk: Something about friend and friendship Ask the Ss to describe one of their friends----their appearance, personality, hobbies, etc.Qs: What’s your friend like?
What does he/she like to do in his/her spare time?
What personality does he/she have? Step Two: Discussion
1.Writing the following statement on the blackboard We all agree that to have a good friend , you need to be a good friend.2.Ask the Ss: What do you think of this statement and how can you be a good friend? Let the Ss express their views 3.Have the Ss get into groups of four to list some qualities of a person they would like as a friend.Ss may list: honest, friendly, open-minded, generous, helpful, patient, good-tempered, trustworthy, careful, full of love, caring, responsible, interesting, brave, easygoing, outgoing, warm-hearted, kind, selfness, tolerant, intelligent… 4.Have a member of each group report on what their lists have and list them on the blackboard 5.Ask the class whether or not they agree with all the qualities listed Step Three: Doing the survey and explanation 1.Have the Ss do the survey in the textbook and let them work out their score.2.Teacher explain each item Question 1 deal with how thoughtful you are towards others.The scoring reflects your concern for others.So one point for A gets the lowest score because it is the most selfish response.B get the highest score because it show a concern for your friend as well as your wish to go to see a film.C gets a slightly lower score because although it shows you want to go with your friend(because you change the plan), you do not help your friend.Question 2 is concerned with fairness.A gets the lowest score because you are not giving your friend another chance to behave better this time.B gets a higher score because you let your friend borrow the camera again.This shows kindness and forgiveness or the trouble you had when it was returned broken.But you are not balancing his heeds against your own.That is why C gets the highest score.You are showing your friend that you will trust him/her with the camera again but this time you are giving him / her rules in case it gets broken.嘉兴英语教学网 www.xiexiebang.com 收集整理
Question 3 deals with your concern for others.A get the lowest score because you would put anything else that needed to be done aside and concentrate only on your friend.This is not responsible.You have things that you need to do.Of course your friend is important but not more important than you responsibilities.B gets a higher score because it shows some concern for your friend and some understanding that you have important things to do too.But it does not show any real interest in his / her problem.C get the highest score because it not only shows concern for your friend but a recognition that you have responsibilities too.Question 4 is concerned with responsibilities to a friend.A provides the correct amount of responsibility to your friend.You recognize that it was your fault and will put it right and pay for the damage.So it gets the highest score.B provides some understanding that you are responsible.You put the situation right but you do not pay for the damage yourself.So it does not get the highest score.C gets the lowest score because you expect your friend to pay for your mistakes even though you were doing your friend a favour.Question 5 is concerned with honesty.If you let your friend look at your paper or somebody else’s paper, you are helping them to cheat.That is not honest, so answers A and C get no marks.But it takes courage to tell your friend that they should have studied and that they cannot look at your paper.That is also the honest answer.So you get 6 points for B, which is more than any other in the quiz.Step Four: Language points Teacher explain language points with some slides 1.add v.1)to put together with something else so as to increase the number, size, importance, etc.增加,添加

第三篇:《荷塘月色》教案(人教新课标版必修2)
荷塘月色【背景材料】
一、作者简介
朱自清原名自华,字佩弦,号秋实。祖籍浙江省绍兴市,1898 年生于江苏省东海县。1903 年随家定居扬州,故自称“我是扬州人”。1916 年中学毕业后,考入北京大学预科班,次年改为“自清”,考入本科哲学系。以后的五年里在江苏、浙江等地的中学教书。在大学时代,朱自清就开始创作新诗,1923 年发表的长诗《毁灭》,在当时的诗坛上产生了很大的影响。1929 年出版诗集《踪迹》,1925 年任清华大学教授,创作转向散文,同时开始了古典文学的研究。1928 年出版了第一本散文集《背影》,成了文坛上著名的散文作家。
1948 年 8 月 12 日,朱自清病逝于北京。他的一生既是作家、学者,又是民主战士。逝世后整理出版有《朱自清文集》(四卷)、《朱自清诗文选集》。
二、月夜有无蝉声?
《荷塘月色》中有一处写到作者在月下漫步荷塘时听到了蝉声。
“这时候最热闹的,要数树上的蝉声与水里的蛙声;……”
后来有一位叫陈少白的写信给朱自清,说蝉子夜晚是不叫的。朱自清为此问了好几个人,他们也都认为陈的话不错。朱自清为了进一步弄清问题,又去请教他在清华大学的同事昆虫学家刘崇乐教授。刘崇乐则从别一个人的著作里摘抄了一段文字寄给朱自清,这一段文字说月夜确有蝉声,不过那位著者又说,平常夜晚蝉子是不叫的,那一个月夜,却听到它们在叫。这么一来,朱自清反复考虑,就把“好几个人”的话当作“客观实际”,而把那个著者的亲耳所闻当作“是个例外”,至于自己文中那一段描写,则自认是“记忆错误”。于是朱自清给陈少白复信,表示了感谢,并且慎重表示:散文集《背影》(里面收有《荷塘月色》一文)以后再版要删掉月夜蝉鸣的句子。
过了些时候,陈少白又在《新学生》月刊上发表文章,再次讨论这个问题,并且涉及到宋代王安石的《葛溪驿》一诗,因为这首诗里也有月夜蝉鸣的描写。也就在这个讨论之后,朱自清自己又有两次亲耳听到了月夜蝉声,“跟《荷塘月色》中所叙的有相同的地方”,朱自清因为“有切己的问题在心里’,所以对此印象格外深刻。这才写了《关于“月夜蝉声’》一文,公开作答。从这番周折中可以看出朱自清对写文章是极其认真负责,绝不含糊的。
朱自清还从这件事中引出一个更深的教训,他在作答的文章中深有感慨地说:“我们往往由常有的经验作概括的推论。例如由有些夜晚蝉子不叫,推论到所有夜晚蝉子不叫。于是相信这种推论便是真理。其实只是成见。这种成见,足以使我们无视新的不同的经验,或加以歪曲的解释。我自己在这儿是个有趣的例子。”朱自清这一段话意味深长,它告诉我们轻率的推论会使人们误把成见认作真理,妨碍我们获得新的经验,接受新的知识,这个体会和认识已经远远超出“月夜”有无“蝉声”的讨论本身了。
三、荷塘夕照明——怀念朱自清先生
今年(1978)八月十二日,是朱自清先生逝世三十周年。清华大学为了纪念他,把座落在“水木清华”池边的古老方亭命名为“自清亭”。它和附近小山坡上纪念闻一多先生的“闻亭”比邻而立。朱、闻两位老教授,都是毛泽东同志称颂过的“表现了我们民族的英雄气概”的爱国知识分子。
“自清亭”的命名,使我想起解放初清华园的荷花池畔,也曾为纪念他而建过一个草亭,名“荷塘月色’。那草亭早因破旧而拆除了,可是,那荷塘呢?
夏日的黄昏,刚下过一回阵雨。雨过天晴,我信步来到荷花池畔。荷塘一片碧绿,间杂着朵朵莲花,微风中送来阵阵清香。
我想起了朱自清的散文《荷塘月色》,这是我在中学里读过的。在解放前,到清华念书的时候,我打听到朱先生笔下的荷塘,就是这个荷花池,走去一看,原来不过是一湾死水,几树垂杨,败叶残花,潦倒其间。塘中央还有座小岛,岛上杂树丛生,荆棘遍地,偶尔还从斜刺里跑出一两只野兔来,人称荒岛。
朱自清写《荷塘月色》的时候,这里是“阴森森的有些怕人”,“白天也少人走,夜晚更加寂寞”。这篇文章的头一句话是:“这几天心里颇不宁静”,这冷僻而又有几分清幽的荷塘月色,就正好成了他“什么都可以想,什么都可以不想”的暂时“自由”“独处”的地方了。
我那时虽是工学院的学生,由于爱好文艺和对朱先生的倾慕,对清华园里的进步文艺活动,总是要挤进去听听的。朱自清经常出席文艺晚会,发表演讲。他这时已不是我想象中风度潇洒的诗人,而是一个扶着手杖,身材瘦小的老人了。但看去精神却很好。他认定了前进的方向,提出要做“向下的”知识分子,即接近工农大众的知识分子。他领头发表反对国民党打内战的和平宣言,在抗议国民党反动派逮捕学生的争人权宣言上签名,起草教授罢教宣言,还常扶着手杖去征集签名。“但得夕阳无限好,何须惆怅近黄昏”。他这用以自况的诗句,表明晚年的朱自清的确不再是写《荷塘月色》时感伤独处的朱自清了。
朱自清写过一首《挽一多先生》的诗,称闻一多是“一团火”,那么,自清先生又该比作什么呢? 他同闻一多的性格是大不相同的,也许是一池清水吧。虽是清水,也会时起波澜,甚至卷起千堆雪。不是吗? 你看他在 “一·二九”运动中,跟随清华学生游行队伍进城,“一·二一”运动中,他到灵堂向四烈士致敬。闻一多被害时,他冒着危险,在成都各界人士追悼会上发表演说。他宁可饿死,不领美国“救济粮’。他在日记中写道:“此事每月须损失六百万法币,影响家中甚大,但余仍决心签名……此虽只为精神之抗议,但决不应逃避个人责任。”在弥留之际,他还一再嘱咐家人不去买那出卖中国人灵魂的“救济面粉”……
在池塘边漫想,清华园这些年的风风雨雨,更教人心潮难平。从朱自清的诗句,想到叶帅的“老夫喜作黄昏颂,满目青山夕照明”。这两句诗反映了我国老一辈革命家的壮志豪情;我想,也反映出今天老知识分子们的心境吧。而《荷塘月色》呢,该另有新篇了。
(摘自《光明日报》)
四、《采莲赋》参考译文(罗定五)
漂亮的少年、美貌的少女,心心相印采莲去。鹢首船头来回转,交杯频递笑把爱情传。桨板轻摇水草紧绊,船头微动浮萍才分开。姑娘身材多窈窕,白绸衫儿束细腰。情意绵绵难分割,恋恋不舍把头回。春末夏初好季节啊,叶儿正嫩花儿才开。撩水逗乐笑微微,怕水珠溅身弄湿衣。忽然又觉船儿斜,急忙收起绫罗裙。【示范教案】

一课时教学内容与步骤
一、解题:荷塘月色(加点部分板书,下同)是朱自清的早期散文作品之一。荷塘,是指作者任教的北京清华大学清华园里的荷花池,表明作者所要描绘的特定处所。月色是文章描绘的中心,它是作者心目中向往、追求的和谐宁静的境界。
朱自清在青年时代曾参加过“五四”运动,向往过俄国十月社会主义革命,后来也投身过反对北洋军阀的斗争。1927 年,蒋介石叛变革命,中国革命处于低潮,朱自清陷入苦闷之中。他既对现实不满,又不敢投入火热的革命斗争中去,因而借赏景来排遣苦闷。本文中所反映出来的憎恶现实,想找一个安宁的所在而不得的苦闷心情,在当时一部分正直的知识分子中很有代表性。
二、学生默读课文,参照“练习”一,初步理解文章的意思。
三、教师先读课文、正音并解释词语。
四、理清全文的段落。教师归纳:全文分三大段。第一大段,(即第 1 自然段),写作者夜深人静时去荷塘观赏月色的缘由。第二大段,(2—6 自然段)是全文的主体,细致地描绘荷塘月色的迷人、恬静,抒发作者淡淡的喜悦和哀愁。第三大段(末两个自然段),写江南采莲习俗及惦念江南之情,表达了作者对美好生活的向往。全文结构完整,衔接自然紧密,写景与抒情有机地揉合在一起。
五、讲读第一段。
(一)指名朗读。
(二)提问:作者为什么惦念起荷塘来了?作者写自己离开沉浸在寂静中的家有什么用意?
师生共同谈话,注意“忽然”两字。
月亮升高了,马路上孩子们的嬉笑声听不见了,妻子拍着闰儿也渐入睡。周围已经沉静下来了,本来可以好好想一些问题,但是,许多的事萦绕在自己头脑中,无法理清,“忽然”想起了荷塘,作者是为了排遣内心的烦恼,找寻片刻的心灵的宁静而去荷塘边的。
第一句是全文的“文眼”,它象是一支乐曲中的主旋律,在全曲中回荡。
六、讲读第二段:
(一)提问,这一段是按照什么线索来写的?学生回答,教师归纳:这一段是按照作者
漫步荷塘的过程来写的。按照作者的活动、视线的转移,有层次地展现荷塘月夜的美丽景色,抒发作者的感情。
小路(第 2 节)——荷塘(第 4 节)——月色(第 5 节)——荷塘周围的树(第 6 节)
漫步——思索(线索)(板书)
(二)讲读第 2 节:
文章先写去荷塘必经的小路。提问:这条小路有些什么特点?学生回答,教师归纳:作者抓住了小路的曲折、幽僻,多树的特点(板书),这三者中,幽僻是主要的特点。曲折与多树是构成幽僻的重要条件。小路沿荷池而筑,随荷池弯曲,呈曲折之态。多树则蓊蓊郁郁,更显幽深僻静。
文章用了对比的方式,衬托出月下小路的美。看看作者是怎样进行对比的?
用白天(少人走)、一般的夜晚(更加寂寞)、没有月光的晚上(阴森森的)和今天的淡月比,写出景色朦胧,富有诗意,第一次把“月色”点了出来。
(三)讲读第 3节:
提问:这一节写作者去荷塘时的感受,请你说说这种感受的具体内容?
学生回答。教师归纳:请学生把“象今晚上,……现在都可不理”这段话划出来。这是作者感受的具体内容。作者感到在这种幽僻的坏境之中,自己成了一个自由的人。在这种环境里,可以不做违心的事,不说违心的话,可以无拘无束、自由自在,抛弃尘世间的喧嚣和烦恼。联系文章的写作背景,可以理解这种感受,表达了作者对自由宁静生活的向往和对黑暗的社会现实的不满,进一步点明了夜游的原因。
(四)讲读第 4 节:
背诵课文第四段,讨论以下问题。
(1)作者写月下的荷塘景物顺序是如何安排的? 有何特点?
先总写荷塘,再写叶子、荷花、荷香、荷波和流水。定点观察,由近及远,由上到下,先静态后动态。
(2)鉴赏景物特色及语言技巧
荷塘
曲曲折折
用叠词,突出广度
荷叶
田田
用叠词,突出密度
像亭亭的舞女的裙,用比喻,以动写静,写出了高而圆的风姿
荷花
袅娜,拟人,饱满的花朵姿态柔美
羞涩,拟人,含苞欲放的娇美情态
明珠,比喻,晶莹剔透地闪光,暗写月光柔和
星星,比喻,忽明忽暗地闪光,暗写月光柔和
美人,比喻,纤尘不染的美质
荷香
远处高楼上渺茫的歌声,通感,将嗅觉形象诉诸听觉形象,时断时续,若有若无,轻淡飘渺,沁人心脾,扩大意境,烘托环境优雅、宁静,这是月夜独处的独特感受
荷波
闪电,比喻,突出快速
凝碧,以静写动
流水
脉脉,拟人,默而有深情
(3)归纳月下荷塘的总体特点,寄寓的感情素淡,宁静,寄寓了淡淡的喜悦之情。
(五)讲读第 5 节:
背诵课文第五段,讨论以下问题。
(1)这一段是从哪几个方面来描写荷塘上的月色的?
先写月光,再写月影,最后写光与影。
(2)作者选用了哪些动词来描写月光,有什么好处?
“泻”,照应“月光如流水一般”中的“流水”这个喻体,增强动感,表现了月辉照耀、一览无余的情景。
“浮”,水气轻轻升腾,慢慢扩散、弥漫,以动景写静景,以“青雾”衬“月光”,表现了月光的朦胧、淡雅。
“洗”,“牛乳”的比喻承上文“泻”字而来,一个“洗”字表现了月光洁白柔和而又鲜艳欲滴。
“笼”,“梦”的比喻承上文“浮”字而来,一个“笼”字表现了月光下叶子与花的轻飘柔美的姿容,衬托了月光的朦胧、柔和。
(3)月光朦胧、柔和的原因是什么?“酣眠”比喻什么?“小睡”比喻什么?作者为什么说“恰是到了好处”?
原因是天上有一层淡淡的云。“酣眠”比喻朗照,“小睡”比喻淡淡的云遮住了满月的意境。这种朦胧柔和的恬淡正合作者此时的心境,所以说“恰是到了好处”。
(4)作者为什么又要写月影?哪个动词用得精妙?
荷塘四周有蓊蓊郁郁的树。月影当是景中一景,塘上月光、塘中月影交相辉映,能使月色表现得更为精妙。
一个“画”字用得精妙,仿佛有无形的手在展纸描绘一般,富有情趣,表现了作者的喜爱之情。
(5)写光与影运用了什么修辞方法?有什么好处?
运用了比喻与通感的手法。将视觉形象化为听觉形象,光与影的黑白块儿仿佛变成了活泼跳跃的音符,化静为动,写活了。光与影的和谐分布与名曲的优美、悠扬、和谐动听,两相烘托,扩大了意境。
(6)这段描写荷塘上的月色,总体特点是什么?寄寓了作者怎样的思想感情?
朦胧,和谐,寄寓了作者淡淡的喜悦之情。
七、讲读末两节。写夜游荷塘引起的联想,想到古代诗词中对采莲的描绘从而引起对江南美好生活的怀念,表现了作者对眼前的寂寞、毫无生气的环境的不满之情,进一步表现了作者内心的不平和对光明美好生活的憧憬、向往。在思乡的哀愁中结束全文。
八、写作特点:
本文语言朴素典雅,准确生动,富有韵味。作者是如何使语言表达得如此美的?
(1)作者精心选用恰当的动词,使语言准确、贴切,创造出生动的意境。
(2)作者善于运用叠词,传神地描写事物特征,加强语气,舒展文气,增加音韵美,深化物态情貌。
(3)作者善于运用比喻、拟人、通感等修辞手法,使语言形象生动,创造出引人入神的意境。
九、归纳中心思想。让学生归纳,教师总结。从荷塘月色美丽景色的描绘中,表露了作者对黑暗的社会现实的不满和对美好生活的向往。总结、扩展
领悟作者的思想感情,要善于通过鉴赏作者的景物描写去把握其中寄寓的情感。而鉴赏作者的景物描写,要善于分析景物描写的层次、景物描写的技巧造成的效果,要品味景物的特点,最后归结到美感特征。
课外阅读朱自清的另一篇散文《绿》,领悟寄寓在梅雨潭的绿中的思想感情,并与《荷塘月色》表现的思想感情进行比较。布置作业
自由命题写一篇情景交融的散文,要求运用比喻、通感的修辞方法,在选用动词与叠词上下点功夫。

余虽好修姱以羁(羁,马缰绳和马笼头。此处名词用作动词,约束、束缚。)
屈心而抑志兮(屈,动词的使动用法,使„„屈;抑,动词的使动用法,使„„抑。)
伏清白以死直兮(伏,为动用法,为„„而伏;死,为动用法,为„„而死。)
高余冠之岌岌兮(高,形容词的使动用法,使„„高。)
长余佩之陆离(长,形容词的使动用法,使„„长。)
四、特殊句式
不吾知其亦已兮(宾语前置句,“不吾知”即“不知吾”。)
高余冠之岌岌兮,长余佩之陆离(定语后置句,“冠之岌岌”即“岌岌之冠”,“佩之陆离”即“陆离之佩”,“之”是定语后置的标志。)
余虽好修姱以羁兮,謇朝谇而夕替(被动句,“羁”“替”,此处均为被动词:被约束,遭贬黜。)
虽体解吾犹未变兮(被动句,“体解”的主语是“吾”,承后省略,是被动者。这是一种意念上的被动。)
五、文学常识
1.屈原(约前340—前278),战国末期楚国人,杰出的政治家和爱国诗人。名平,字原。他出身于楚国贵族,与怀王同祖。屈原学识渊博,善外交辞令。在政治上他推崇“美政”,即圣君贤相的政治,认为只有圣君贤相才能把国家治理好,有强烈的忧国忧民、忠君致治的思想。因受小人陷害,他两次被流放,最后投汨罗江而死,以明忠贞爱国之怀。在流放期间,他以其出众的才华和对祖国人民的热爱,写下了《离骚》《九歌》《天问》《九章》等不朽的诗章。他开创了诗歌从集体歌唱转变为个人独立创作的新纪元,是我国浪漫主义诗歌的奠基人,我国第一位伟大的爱国诗人,世界四大文化名人之一(另有波兰哥白尼、英国莎士比亚、意大利但丁)。
2.“楚辞”是战国时期兴起于楚国的一种诗歌样式,是以屈原以及宋玉的作品为主体的诗歌总集。其中最有代表性的是屈原的代表作《离骚》,因此后人又把“楚辞”的体裁称为“骚体”。《离骚》与《诗经》在文学史上并称“风骚”。
六、名篇名句
1.长太息以掩涕兮,哀民生之多艰。
2.忳郁邑余侘傺兮,吾独穷困乎此时也。宁溘死以流亡兮,余不忍为此态也!3.民生各有所乐兮,余独好修以为常。虽体解吾犹未变兮,岂余心之可惩? 4.亦余心之所善兮,虽九死其犹未悔。句段剖析
一、疑难妙句
1.长太息以掩涕兮,哀民生之多艰。
译文:我长声叹息止不住泪流满面,哀怜着人民的生活多么艰难。
剖析:表现了诗人的极度苦闷和难以排解的心情,为下面情绪的抒发定下了基调。这两句承上,形象地概括了诗人忧国忧民的博大情怀,给我们塑造了一位“先天下之忧而忧,后天下之乐而乐”的诗人形象。
2.怨灵修之浩荡兮,终不察夫民心。众女嫉余之蛾眉兮,谣诼谓余以善淫。
译文:怨恨君心荒唐啊,始终不能理解我的心思。那些女人也嫉妒我的妩媚,诽谤我好放荡淫乱。
剖析:这几句诗使抒情主人公除了作为政治家和诗人的自我形象出现外,又常幻化为一个美丽而遭逢不幸的女子。她有爱美的天性,喜欢用芳洁的东西修饰自己,还亲手栽培了许多芬芳的草木。起初与丈夫(“灵修”有时也可理解为丈夫)缔结了婚约,后来却受到众女的嫉妒和谗毁,终于被抛弃。这一条“美人香草”式的寓意伏线和诗人的政治抒情叠合在一起,www.xiexiebang.com

节选内容每两句一小节,可以分为两个部分:
主旨探讨
关于本文的主旨有如下表述:
1.诗人自述品质、政治理想以及自己的忠诚,表现了屈原坚持“美政”、至死不悔的高尚节操,抒发了诗人忧国忧民、献身理想的爱国情感。
2.作者回顾自己从政遭遇的艰难,写了自己与小人之间的矛盾不可调和,也表明了自己不为君王理解的苦闷之情,并抒发了自己对楚怀王的怨愤。
我的观点:_________________________________________________________ 审美鉴赏
血泪凝结成的生命挽歌
——浅析《离骚》中屈原的悲剧形象
屈原一生经历了楚威王、怀王、顷襄王三个时期,而主要活动于楚怀王时期。这个时期正是七雄纷争,各国存亡处于紧要关头的战国时代,诗人的理想就是把祖国推上强大、富裕的道路。
大家知道,儒家高扬道德大旗,主张克己修身,齐家、治国平天下。受儒家思想影响的屈原,不仅把“修能”(修饰才能)作为圣人的目标,而且具有浓厚的以圣人自诩的倾向。他在诗中借香草喻内在的美德,用美人喻理想中的君王,用荃草喻现实中的君王,用采摘和披挂江离、秋兰喻修身养性,用乘骐骥喻追求和实现美好的政治理想„„所有的这些都刻画出高洁动人的抒情主人公形象。他试图以道德理想促成“美政”理想的实现,通过高扬道德理性来整治政治秩序。然而,事实上,他发现现实中的楚王与理想中的圣王之间存在明显差距。于是,对楚王的怨愤和对“党人”的鄙弃萦绕于怀,诗人最终遭谗见废,导致“美政”理想的幻灭,“忧愁幽思而作《离骚》”。屈原悲剧性的人生结局,令人深思。
这位伟大的爱国诗人,在昏庸的君王面前,在奸邪的“党人”面前,既不能改变自己,也不能改变楚国,且又不愿离开自己的祖国(“忍而不能舍也”),只能选择以死明志,去殉他www.xiexiebang.com
