    人教版高中語文必修1《雨巷》說課稿3篇

    一.教材理解教材地位與作用:本單元“閱讀與鑒賞”部分,本單元要求學生能在了解詩歌創(chuàng)作的時代背景的情況下通過反復誦讀詩歌,把握其中豐富的意象,領悟詩歌獨特的意境和詩人所要表達的情感?!队晗铩肥乾F(xiàn)代派大師戴望舒的成名作和前期的代表作,他曾因此而贏得了“雨巷詩人”的雅號。本單元以《雨巷》為例子給學生展示了象征主義詩歌的特點,《雨巷》運用了象征性的抒情手法。詩中那狹窄陰沉的雨巷,在雨巷中徘徊的獨行者,以及那個像丁香一樣結著愁怨的姑娘,都是象征性的意象。這些意象又共同構成了一種象征性的意境,含蓄地暗示出作者即迷惘感傷又有期待的情懷,并給人一種朦朧而又幽深的美感。富于音樂性是《雨巷》的另一個突出的藝術特色。詩中運用了復沓、疊句、重唱等手法,造成了回環(huán)往復的旋律和宛轉悅耳的樂感。因此我把本課的教學重點和難點確定為:教學重點:通過反復誦讀,領略詩歌的音樂美以及分析其成因教學難點:分析意象以及其象征意義初步掌握鑒賞詩歌的方法

    本文篇幅較長,并且有一字句不易理解,因而對高一學生來說完全讀懂內(nèi)容有一些困難。這樣的話,老師就要做好引導工作,把一些難點,或是出現(xiàn)詞類活用比較多,局勢比較特殊的句子,老師可以先給學生畫出來,存疑,或是與同學們一起討論解決。對那些不易懂的字詞就引導學生聯(lián)系上下文提供的語境、前后涉及的情節(jié)加以推測、判斷,以培養(yǎng)學生依據(jù)文脈推斷詞義的好方法。要求學生點出重點實詞、框出通假字,主要是為幫助學生積累和掌握一些文言文中常見的一詞多義、異讀現(xiàn)象、古今異義和通假現(xiàn)象的詞語,并進一步得出規(guī)律,指導今后的文言文學習。詞類活用和特殊句式在文言文翻譯中難度較大,也是本文教學的兩大難點。要求學生標出有活用現(xiàn)象的字和劃出句式特殊的句子,是基于兩點考慮:1、積累一定數(shù)量的第一手例句;2、引導學生加以分類,找出每類的相同特征,并抽取出來形成規(guī)律性的東西,從而上升到理性認識,使學生能由學會一個到會學多個。翻譯過程中注重指導學生養(yǎng)成用符號法表示重點字句的好習慣,如點、框、圈、劃線等符號應約定一致,便于突出翻譯中的重點、難點及復習。我的提示著重歸納了實詞“制”“亡”“遺”“利”等,名詞活用、形容詞活用、使動用法,被動句、狀語后置句。

    《勸學》是普通高中課程標準試驗教科書語文必修三第三單元的重點篇目,該文集中反映著名思想家荀子在學習問題上的觀點和精彩斐然的論證藝術。該單元所選課文都是古代的議論性散文。通過本單元的學習在于讓學生感受我國傳統(tǒng)文化的精神,掌握基礎的文言語法知識,學習如何清晰有力的表達自己的思想和見解。本文安排在單元的第一篇,如何指導學生學好這篇課文,是實現(xiàn)“授之以漁”,樹立學生學好文言文的信心,掌握文言學習方法的關鍵。根據(jù)新課標倡導從“知識與能力”、“過程與方法”、“情感態(tài)度與價值觀”三方面出發(fā)設計課程目標的要求和高一的學生對于文言文的知識還在積累的階段,應該注重基礎知識的積累和一定量的誦讀的實際情況。我擬確定以下教學目標:1,了解荀子論述學習的思想,明確學習要靠積累、堅持不懈、專心致志的道理。2,掌握積累文言實詞、虛詞,活用、古今異議等現(xiàn)象和固定句式。

    Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting.

    ①平動的物體一般可以看作質(zhì)點做平動的物體,由于物體上各點的運動情況相同,可以用一個點代表整個物體的運動,在這種情況下,物體的大小、形狀就無關緊要了,可以把整個物體當質(zhì)點。例如:平直公路上行駛的汽車,車身上各部分的運動情況相同,當我們把汽車作為一個整體來研究它的運動的時候,就可以把汽車當作質(zhì)點。當然,假如我們需要研究汽車輪胎的運動,由于輪胎上各部分運動情況不相同,那就不能把它看作質(zhì)點了。要注意的是:同一物體在不同情況下有時可看質(zhì)點,有時不可以看作質(zhì)點,一列火車從北京開到上海,研究火車的運行的時間,可將火車看成質(zhì)點,而火車過橋時,計算火車過橋的時間,不可以將火車看成質(zhì)點。②有轉動但轉動為次要因素例如:研究地球公轉時,可把地球看作質(zhì)點;研究地球自轉時,不能把地球看作質(zhì)點。③物體的形狀、大小可忽略再如:乒乓球旋轉對球的運動的較大的影響,運動員在發(fā)球、擊球時都要考慮,就不能把乒乓球簡單看作質(zhì)點。
