《鸟啼》教案教学目标：1、体会大自然中存在的生命意义。
2、体会劳沦斯对生与死的思考。
教学时数：一课时教学过程：一、导入今天早晨的大雾大家都看到了吧？我自己骑车过来的时候，周围的一切都笼罩在一片白色之中，增加了很多的美感。
但是我发现人的视力差了之后，听力似乎有了提高，当我走进校园的时候，听见我们校园内很多树上都有鸟，而这是通过听力发觉的。
很多的鸟的声音都很好听，但是老师仅仅是觉得好听而已，如果说要听出更深的内涵，我们不妨从劳伦斯的文章里去看看。
今天我们一起学习他的《鸟啼》。
（板书：鸟啼）二、文本研习1、请学生朗读第1——8节，然后请同学说说文中哪几段有对鸟啼的描写？能不能找到具体的句子呢？明确：分布在2、3、4、5、8五个段落里。
2、找到后，请在文中划出修饰鸟啼的词语，比较有什么不同。
明确：A．缓慢、笨拙、吃力、微弱、隐约、含糊、若断若续B．清越、明快、活泼、悦耳、清明、生动、轻柔、欢快可大致分为两种类型：微弱的和清越的。
3、由此我们看看鸟啼声是如何变化的？能否用简洁的语言概括鸟啼变化的过程？明确：这组词描述准确，写出了鸟啼声由小变大、由弱变强。
（联系第8节最后“我们听到了鸟儿们发出的轻柔而明快的隆隆鼓声”）4、这样的鸟啼声自然让人惊讶，令作者惊讶的还有其他原因吗？比如我们教室窗外的鸟啼会不会让你也有这样的感悟？（不会，因为环境不同）那么文中的鸟啼是在什么环境之下听见的？请同学齐读第一节，这一节中给你印象较为深刻的是哪几个词语？表达了冬天怎样的景象？明确：“数不清的腐鸟的血衣”。
可见英国的冬天严寒持续，鸟尸横陈，到处充斥着死亡的气息。
（板书：鸟尸）5、写到鸟尸的段落除了第1节在前8段还有其他地方吗？请同学读一下。
明确：3、7、8三段中都有所提及。
6、这样看来，鸟啼和鸟尸都是有象征意义的，那么各有何象征意义呢？从写作上来讲，这里写鸟啼和鸟尸用了什么表现手法？明确：“鸟啼”是新生命的象征，象征严寒过后新生命的到来。

Here are some pictures. They are all very famous places in China or in the world. Please think these over:A.Can you name them out?B.Who have the right to own and confirm them?(The shown pictures:①The Great Wall, ②The Imperial Palace of the Ming and Qing Dynasties in Beijing and Shenyang; ③The Mausoleum of the First Qin Emperor and the Terracotta Warriors) Let the students name out the famous places in the pictures, and tell them they are cultural relic s. And explain what cultural relics are.A. a cultural relic is sth. that survive d for a long timeB. a cultural relic may be a part of old thing has remain ed when the rest of it had beendestroyedC.or a cultural relic is something rather rare（while showing these photos, teach the new words in red: cultural relics, survive, remain, rare）1. Get the students understand the identity of the cultural relics.2. Let the students try to know that they are at least two sites of cultural relics, the natural site; and the cultural site.( By showing the pictures of some natural sites relics. Eg: Mount Huashan, The JiuZhaiGou Valley, River Li )Step Two: DrillsLet the students make some more examples of cultural relics, including the ones inside our country or in other countries, especially the ones in our location.Here are some possible answers from the students:(The Neiguan Cave(内莞岩); The Xinfengjiang River(新丰江); Heyuan Dinosaur Park(河源恐龙公园); Yuanmingyuan(圆明园), etc.)(The Sydney Opera; The White House; The Big Ben; The Amber Room, etc.)Step Three: Discussing 1As we all know that cultural relics are rather valuable, rare, and sometimes, it is in very high price.1. Then can you tell the value of the cultural relic? (Have the students discussed for some time in teams, then get their answers by expressing in class.)(There will be a lot of possible answers. Eg: From the cultural relics we can know what people didin the past, and we can know the cultures at that time, and maybe we can know the technology of making them…)2. How to protect the cultural relics? (The same as Question 1)(There will be a lot of possible answers. Eg: Having the idea of protecting our cultural relics; don’t damage them; use them in a right way…..)Step Four: Discussing 21. If you find a cultural relic, what will you do with it?2. Do you think to whom the cultural relics belong?(All cultural relics belong to all people and whole society.)Have the students to discuss the first question for about two or three minutes, then show the answer for their team. Then the same way for Question 2.(While discussing, teach the new phrase in red)The Second Period(Reading part, 2-3 classes)Teaching Aims:1. Reading and understanding, catching the history and information of the Amber Room.2. Functional item, how to tell the story about the Amber Room3. Grammar point: The Attributive Clause4. Learning the following useful words and phrases:in search of, fancy, style, jewel, in return, reception, light, mirror, wonder, at war, remove, furniture, secretly, wooden, doubt, remain, mystery, apart, take apartTeaching DesignStep One: PresentationLast period, we talk about the cultural relics at home and abroad, such as The Great Wall, The Imperial Palace of the Ming and Qing Dynasties in Beijing and Shenyang; The Mausoleum of the First Qin Emperor and the Terracotta Warriors The Sydney Opera; The White House; The Big Ben; The Amber Room (which we have learnt last period)Then, we will go the Amber Room, showing them the pictures of it.Do you know the history of the Amber Room, and do you know where the Amber Room is now? (The Amber Room is a room built by lots of ambers. It was a gift given to Peter the Great, the King of Russia, by the King of Prussia, Frederick William I. It was given the name because almost seven thousand tons of natural ambers were used to make it. But during World WarⅡ in 1941, the Nazi German army secretly stole the Amber Room and sent boxes of the Amber Room on a train to a German City. After that, what really happened to the Amber Room remains a mystery.) Step Two: Reading 1 (Listening, reading and understanding)1. Now please listen to the tape of the text IN SEARCH OF THE AMBER ROOM. And then read aloud. Pay attention to the pronunciation of each word and the pauses within each sentence.2. After reading the text, please complete the exercises of Comprehending.①Keys to Ex1 CEBDAF②The suggested answers to the Ex2Para 1 How was the Amber Room made?Para 2 Why did the King of Prussia give the Amber Room to the Czar of Russia as a gift? Para 3 How did the Amber Room become one of the wonders of the world?Para 4 How did the Amber Room get lost?Para 5 How was a new Amber Room built?3. Detailed ReadingRead the text again and answer the following questions:①.What was given to the Russian people as a great gift by Frederick WilliamⅠ,the Kingof Prussia?(The Amber Room was given to the Russian people as a great gift by Frederick WilliamⅠ,the King of Prussia )②.Why it is called the Amber Room and how many tons of amber were used to make theAmber Room?(Because it was made of seven thousand tons of amber, which has a beautiful yellow brown color)③.What did Catherin eⅡ do with the Amber Room?(She had the Amber Room moved to the palace outside St Petersburg and transformed it.)④. What happen to the Amber Room during World Wa rⅡ?(It was stolen by the Nazi and it was taken apart and missing in World WarⅡ)Step Three: Intensive ReadingSkimming and identifying the general idea of each paragraphNow please read the text again and try to catch the main idea of each paragraph. After about five minutes reading, have some students speak for their teams.1st paragraph: the introduction of the Amber Room(The Amber Room had a strange history and something about its design, color, shape and material.)2nd paragraph: the gift to the Czar(the history of the Amber Room and its use in Russia—the Czar’s winter palace and a small reception hall for important visitors.)3rd paragraph: the relocation of the Amber Room in CatherineⅡ time(CatherineⅡhad the Amber Room moved to the palace outside St Petersburg told the artists to add more details to it.)4th paragraph: the missing of the Amber Room(the German Nazi stole the Amber Room secretly during the World Wa rⅡ,and what really happen to the Amber Room remain a mystery)5th paragraph: the rebuilding of the Amber Room(Russia and Germany have built a new Amber Room for the 300th birthday f St Petersburg.)Step Four: DiscussingClosing down by having a discussionA.Can you imagine the fate of the Amber Room? What is it?B.Do you think if it is worthwhile to reproduce the Amber Room? Why?Have the students discussed one question by one question for some time, and then show theirviews for their teams. There may lots of possible answers.Keys for reference:A: I have no idea about the fate of the Amber Room. Because anything can happen to it. Maybe it was destroyed at war in the fighting fire. You see, ambers can be melted easily. Maybe it was kept secretly by somebody who had died without telling about it to anyone else. So maybe it is lying somewhere quietly.B: I think it is worthwhile to reproduce the Amber Room. Because it represents the culture and a period of history in St Petersburg. It is a trace and feature surviving from a past age and serving to remind people of a lost time.Step Five: New words teachingRead the reading part paragraph by paragraph again and pick up the key words and phrases by themselves, let the students try to explain the meaning and usage.amazing, select, honey, heat, design, fancy, style, decorate, jewel, artist, belong, in return, troop, light(lit), mirror, wonder, at war, remove, furniture, wooden(wood), doubt, formerEspecially pay attention to the words and phrases underlined.Step Six: Grammar points in this textLet the students try to find out the Attributive clause in warming up and the reading part.1. A cultural relic is something that has survived for a long time.2. It is your job to look into any reports of cultural relics that have been found in China.3. You are sent to a small town where you find a relic that was stolen from a palace.4. The man who has it insists that it belongs to his family.5.This gift was the Amber Room, which was given this name because almost seven thousand tons of amber were used to make it.6. Later, CatherineⅡhad the Amber Room moved to the palace outside St Petersburg where she spent her summers.7. In 1770, the room was completed the way she wanted it.8. This was a time when the two countries were at war.Have the student’s judge whether they are the same as those we had learnt before. Especially the 5th one. This will be the homework after class.The Third Period(Learning about Language, 1-2 classes)Teaching Aims:1.To learn some useful words and expressions2.To learn some useful structures3.To learn the Restrictive and Non—Restrictive Attributive ClauseTeaching Important PointLearn how to use the Attributive Clause with that/which/who/where/whenTeaching Difficult Point:⑴. How to tell the Attributive Clause with that/which/who/where/when from other clauses.⑵. Learn the differences between the Restrictive and Non—Restrictive Attributive ClauseTeaching DesignStep One: Retelling (Can be chosen)Retell the story of the Amber Room in their own words.Step Two: Exercising 1 (Exercise 1 &2 on Page 3)(1) Complete Exercise One in Learning about Language on Page3. Asking and answering activity to check the students’ answers of the exercises; individual, pair of group work or finish each task.Here are the keys to Ex1:1.select2.rare3.reception4.amaze5.less than6.wooden7.in search of8.suivive9.remove10.artist11.former12.at war(2) Read the passage and complete it with the words giving.Keys to Ex2:dynasties, style, amazing, jewels, designed, decorated, fancy, rare, doubt, worthStep Three: Exercising 2 (Exercise 3 on Page 3)Look, think and compareRead over the materials in Ex2 carefully and try to find out the different meanings and usages of the phrase belong to,and try to match the meaning with the given sentences.Keys:1.to be the property of; The coat belongs to me.2.to be a part of, be connected with; That top belongs to this desk.3.to be a member of; He belongs to a large family.Step Four: Grammar point (the Attributive clause)1. Discovering useful structures (on Page 4)Let the students try to find out the Attributive clause in warming up and the reading part.1. A cultural relic is something that has survived for a long time.2. It is your job to look into any reports of cultural relics that have been found in China.3. You are sent to a small town where you find a relic that was stolen from a palace.4.
