巴金在十年浩劫中的大致经历:放弃包弟并没有换得保全一家人,1968年8月,巴金被关进牛棚改造,随后经受了大字报、挂牌游街等形式的批斗。1970年,到农村改造,掏大粪、喂猪、背稻草、种地……1972年,妻子萧珊在饱受精神折磨后患上癌症,病逝。巴金的儿子在劳动改造的过程中也饱受精神和肉体上的折磨,性格变得内向抑郁,疾病缠身。此时,巴金69岁。巴金曾在《病中》一文写道:“当姚文元拿着棒子的时候,我给关在牛棚里除了唯唯诺诺之外,敢于做过什么事情?十年间我不过是一条含着眼泪等人宰割的牛。”小结:(幻灯片12)社会是病态的社会,政治是高压的政治,人性是扭曲的人性。十年文革,十年浩劫,给多少人留下了累累不可弥合的精神创伤。即使一条小狗,也可能摆脱不了“文革”无情的迫害,比如包弟,比如艺术家邻居的小狗。
《小蝌蚪找妈妈》是统编版二年级上册第一单元的一篇寓水的知识于趣味故事中的科学童话。课文采用拟人手法,以第一人称“我”的叙述方式,生动形象地介绍了自然界中水的变化及其利与害。课文用词准确、语言优美、想象丰富,把知识性、科学性融于趣味性之中,文中多处运用短长句的方式写出了语言的节奏感,拟人化的词句增强了画面感,充满情趣。比如“有时候……有时候……”“落”“打”“飘”体现了用词准确、严谨的特点。教学时以学生为主体,让每个人有尝试的机会和自主选择的权利。力求采用自主、合作的学习方式探究问题,解决问题,使学生在生生互动、师生互动中,相互启发,拓展思路,分享学习之乐。让学生在开放而有活力的课堂氛围中始终处于积极主动的学习状态,变“被动地学”为“主动地学”。 ·教学目标· 1.认识“晒、极”等15个生字,会写“变、极”等10个生字,读准多音字“没”。掌握“天空、傍晚”等词语。2.能正确、流利、有感情地朗读课文,简单说说水的变化过程。3.了解气候常识,知道汽、云、雨、冰雹和雪都是水的不同形态。知道水的利与害。4.通过学习,让学生知道只有合理地利用水资源才能造福人类的道理,树立环保意识,激发学生探究科学的兴趣。 ·教学重难点· 1.教学重点:能正确、流利地朗读课文。简单说出水的变化过程,体会“落、打、飘”用词的准确,并能仿照说句子。2.教学难点:了解气候常识,知道汽、云、雨、冰雹和雪都是水的不同形态。知道水的利与害。
教学目标:1、了解文学作品解读的个性化及其原因。2、探讨个性化解读遵循的基本原则,合理解读文学作品。教学重点:引导学生关注文学现象,培养他们对文学作品理解的多重思维能力。教学难点:把握个性化的度。避免偏激的理解、过度的张扬所谓个性,严重歪曲文学作品。教学方法:导读、计论、合作探究。教学时间:一课时教学过程:一、创设情境、揭题导入:记得有这样一个故事:一个小孩在四岁就能背《登鹳雀楼》,可平时只有在大人的要求下,他才背出来。直到六岁的某一天,他父母带他去旅游,在他登陆上山顶时,竟然随口背出:“欲穷千里目,更上一层楼”来。这说明了什么?……(讨论)文学作品解读的个性化。二、探讨个性化解读的原因1、读者的差异导致解读的个性化A、同一作品,阅读的时间不同,解读不同。如上面的例子。如《从百草园到三味书屋》和《风筝》主题的多元化理解。“温故知新”,名作重读,不但有趣,而且有益。B、同一作品,不同读者,解读不同。
方法点拨教师:有的同学叙述事实论据时,不突出重点和精华,不注意取舍,水分太多,有许多的叙述描写,有时还有详细的故事情节,文章几乎成了记叙文,使文章的论点无法得到充分的证明,这是写议论文的大忌。那么:议论文中的记叙有哪些特点?同学各抒己见。投影显示:1.议论中的记叙不是单纯的写人记事,记叙文字是为议论服务的,其目的是为作者所阐明的道理提供事实依据。所以,在记叙时要求简洁、概括,舍弃其中的细节,仅仅交代清楚事件或者人物的概貌即可,一般不在各种描写手段上下功夫,只要把能证明观点的那个部分、侧面交代清楚就行了。2.议论文中的记叙性文字不得超过总字数的1/3,否则视为文体不当。能力提升一、教师:了解了议论文中的记叙的特点,接下来我们看看今天的话题:“爱的奉献”,你想从哪个角度立论?有哪些素材?
论证方法之引证法如何用好引证法:1.所引用的名言警句等针对性要强。每句名言都产生于特定的背景,都应用于特定的交际目的,即使谈同一个问题,也有不少名言可供选取。2.要简洁,不宜过多。议论是在发表自己的见解而不是在介绍他人的见解。引用他人的话,目的是为了让读者更加信服自己的话。3.要注意直接引用和间接引用的区别。直接引用务求文字、甚至标点均准确无误;间接引用只须述其大意,但要注意人称的转换。论证方法之喻证法喻证法是用设喻来论证论点的方法。在议论文中,设喻可以使论点更易懂、更风趣、更容易获得读者的认同。喻证法能化抽象为具体、化艰深为浅显、化枯燥为生动。论证方法之喻证法如何用好喻证法:1.以小见大,就近取譬。要精选生活中细小的、人们熟悉的事物做为设喻的喻体。2.喻体不求形似,只求神似。做为喻证的喻体与做为比喻的喻体不同。比喻的喻体是为了强调特征,描绘事物,侧重形似,以形比形;而喻证的喻体是为了阐发观点,以正视听,力求神似,以义取形。
1、变换角度,多向思维(多向思维要求思维能针对问题,从不同角度,用多种方法去思考问题。对于作文而言,就是要使学生学会对同一问题,同一素材,同一题目,同一体裁的不同进行区分。)请学生从这则材料中分析出几个角度,准备课堂交流:19世纪法国著名科幻小说家儒勒?凡尔纳,一生写了104部科幻小说。当初他的第一部科幻小说《气球上的星期五》接连被15家出版社退回。他当时既痛苦又气愤,打算将稿子付之一炬。他妻子夺过书稿,给他以鼓励。于是他尝试着走进第16家出版社。经理赫哲尔阅读后,当即表示同意出版,还与儒勒?凡尔纳签订了为期20年的写作出版合同。这则材料叙述时没有一定的中心,属于开发性材料,分析材料中人物、人物关系、故事的不同侧面,可以从不同角度得出结论:

提问:城市环境污染源主要有哪些?有些同学基本同意自行车多是加剧南京空气污染的间接原因,你同意他们的观点吗?在学生回答的基础上,教师进行归纳小结:工业和交通是城市环境的主要污染源。而自行车是一种绿色交通工具,既环保又经济。只有当它在某些机动车和非机动车不分的地段,影响车辆行驶速度的时候,它才可能成为加剧空气污染的间接原因。问:那我们针对交通工具对环境造成的影响,有什么解决方法吗?归纳小结:? 实施减少汽车尾气污染的技术措施? 加强道路绿化? 合理规划城市道路,提高车速? 制定相关法规严禁各种车辆违规鸣喇叭? 在噪音严重的地区设置先进的隔音设施总结:通过前面的分析我们知道了自行车过多并不是造成北京交通拥挤的主要原因,但自行车多并且不遵守交通规则的确是造成交通拥堵的一个原因。从这方面来讲,在一些混合车道地段,自行车是造成空气污染加剧的间接原因。那么在北京到底是应该鼓励自行车的发展还是限制自行车的发展呢?

Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分,只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition
Step 7: complete the discourse according to the grammar rules.Cholera used to be one of the most 1.__________ (fear) diseases in the world. In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention,the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste. The people who drank this water were much more likely _10_________ (get) cholera than those who drank pure or boiled water. Through John Snow's efforts, the _11_________ (threaten) of cholera around the world saw a substantial increase.

Step 5: After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!
