一、人類遺傳病1.概念2.分類(1)單基因遺傳病(2)多基因遺傳病(3)染色體異常遺傳?、僭颌陬愋?遺傳病的特點(diǎn)4.遺傳病對(duì)人類的危害八、說布置作業(yè)在作業(yè)的布置中,我嚴(yán)格遵循“重質(zhì)量、輕負(fù)擔(dān)”的指導(dǎo)思想。第一題主要是為了幫助學(xué)生及時(shí)糾正原有的對(duì)知識(shí)的錯(cuò)誤理解或片面認(rèn)識(shí),培養(yǎng)學(xué)生的解題技巧和技能。所以我選用了該題。同時(shí)想借助該題培養(yǎng)學(xué)生對(duì)問題的科學(xué)的思維方法和探究的精神。幫助學(xué)生提高對(duì)信息技術(shù)運(yùn)用的熟練程度,發(fā)展學(xué)生的信息素養(yǎng)。附作業(yè):1、連線題,請(qǐng)同學(xué)們連線指出下列遺傳各屬于何種類型?(1)苯丙酮尿病 A、單基因遺傳病(2)21三體綜合征(3)抗維生素D佝僂病 B、多基因遺傳?。?)軟骨發(fā)育不全(5)青少年型糖尿病 C、常染色體病2、以生物小組為單位進(jìn)行人類遺傳病的調(diào)查。

教學(xué)內(nèi)容與分析本課內(nèi)容是大眾傳媒的變遷,首先解題,了解什么是大眾傳媒。大眾傳媒就是傳播大眾信息的媒體,進(jìn)入近代社會(huì)以來,人與人之間的聯(lián)系變得越來越密切,社會(huì)化程度大大加深,需要有一種大眾化、傳播速度快、傳播范圍廣的媒介作為人與人之間進(jìn)行信息溝通的渠道,人類社會(huì)的傳媒手段應(yīng)運(yùn)而生,可由學(xué)生總結(jié)出有哪些主要的方式。報(bào)刊、影視、廣播,這三種大眾傳播媒體的依次出現(xiàn),給人們的生活方式帶來了巨大的變化,被稱為三大媒介。由于互聯(lián)網(wǎng)同報(bào)紙、廣播和電視三大媒介一樣,具有傳播信息的功能,所以被稱為“第四媒介”,即“網(wǎng)絡(luò)媒介”。通過本節(jié)課的學(xué)習(xí)使學(xué)生了解中國(guó)近代社會(huì)生活的變化,體會(huì)歷史和時(shí)代發(fā)展的必然性,能夠站在發(fā)展的角度、用歷史的眼光思考問題。

(1觀察圖解,色盲基因在性別間是如何傳遞的呢?(女--女、女--男、男--女)(2)為什么不能由男性傳給男性?(色盲基因是在X染色體上,因此色盲基因是隨X染色體的傳遞而傳遞。)(3)男性的色盲基因怎樣才能傳給男性呢?(通過女兒,傳給外孫即交叉遺傳)(4)從圖解看色盲在男女中的發(fā)病情況怎樣?(男性多于女性)(5)從社會(huì)調(diào)查也是這樣,你是否能從基因和染色體的角度加以解釋?(提示:女性染色體的構(gòu)成,結(jié)合基因位置及顯隱性進(jìn)行分析)歸納特點(diǎn):歸納出色盲基因遺傳的特點(diǎn)并擴(kuò)展到X染色體隱性遺傳的特點(diǎn)上。色盲基因遺傳(X隱性遺傳)的特點(diǎn):(1)男患者多于女患者(2)交叉遺傳(3)女病兒子必病,男正女兒必正等。問題探討:利用“遺傳圖解”結(jié)合“問題鏈”繼續(xù)探討,拓展到抗維生素D即X 染色體顯性遺傳的特點(diǎn)。(6)色盲基因在X染色體上屬隱性基因,子代表現(xiàn)男多于女,對(duì)應(yīng)的正常色覺基因則屬于X顯性基因,子代表現(xiàn)應(yīng)如何?(女多于男)

設(shè)問:DNA復(fù)制后兩個(gè)子代DNA分子與親代DNA分子是否完全相同?為什么?通過設(shè)問,讓學(xué)生進(jìn)一步理解和鞏固DNA復(fù)制的全過程。接下來讓學(xué)生總結(jié)出DNA復(fù)制的四大基本條件:① 模板:開始解旋的DNA分子的兩條單鏈;② 原料:是游離在核液中的脫氧核苷酸;③ 能量:是通過水解ATP提供;④ 酶:酶是指一個(gè)酶系統(tǒng),不僅僅是指一種解旋酶。最后通過以上分析,總結(jié)出DNA復(fù)制的意義以及在生活中的應(yīng)用:意義:DNA通過復(fù)制,使遺傳信息從親代傳給子代,從而保證了物種的相對(duì)穩(wěn)定性,保持了遺傳信息的連續(xù)性,使物種得以延續(xù)。應(yīng)用:目前DNA分子廣泛應(yīng)用于刑事案件偵破等方面:如:DNA分子是親子鑒定的主要證據(jù)之一。把案犯在現(xiàn)場(chǎng)留下的毛發(fā)、血等進(jìn)行分析作為破案的證據(jù),與DNA有關(guān)。五、設(shè)計(jì)課堂練習(xí):設(shè)計(jì)一題典型課堂練習(xí):即有關(guān)半保留復(fù)制及計(jì)算的習(xí)題:

3、遺傳密碼的特點(diǎn) 連續(xù)性、簡(jiǎn)并性、通用性5、課堂練習(xí)6、作業(yè)布置假如,我們利用(ACU)n核苷酸長(zhǎng)鏈合成了含有蘇氨酸的多肽,那么蘇氨酸可能的密碼子有哪些?如何運(yùn)用實(shí)驗(yàn)方法確證蘇氨酸的密碼子究竟是什么?七、教學(xué)反思1、教材中豐富的科學(xué)史料,是我們?cè)谡n堂上進(jìn)行探究性學(xué)習(xí)活動(dòng)的良好素材,教師要整理和運(yùn)用好。千萬不要低估學(xué)生的思維能力,當(dāng)學(xué)生的思維能力被你想方設(shè)法激發(fā)出來的時(shí)候,你會(huì)發(fā)現(xiàn)他們的創(chuàng)造力是無窮的。2、探究性學(xué)習(xí)的目的并不僅僅是問題的解決,更重要的是在探究過程中體驗(yàn)和獲取科學(xué)研究方法,培養(yǎng)合作與分享的精神以及實(shí)事求是的科學(xué)態(tài)度,鍛煉思維能力,提高科學(xué)素養(yǎng)。3、學(xué)生是學(xué)習(xí)的主體,教師是引導(dǎo)者。我們要采取措施讓學(xué)生積極主動(dòng)地參與到學(xué)習(xí)活動(dòng)中來,通過他們的思考、討論、爭(zhēng)辯、合作等活動(dòng)來獲取方法,建構(gòu)知識(shí)。

四、說教學(xué)程序(一).溫故知新、導(dǎo)入新課復(fù)習(xí)提問:基因突變導(dǎo)致生物變異的原因是什么?回答:基因突變是基因結(jié)構(gòu)發(fā)生改變,從而使遺傳信息改變,使蛋白質(zhì)結(jié)構(gòu)改變、生物性狀改變,即生物發(fā)生了變異。那么,基因是什么?它和染色體又有何關(guān)系?回答:基因是有遺傳效應(yīng)的DNA片斷,染色體是DNA的載體,基因在染色體上呈線形排列。引出新知:對(duì)于一個(gè)生物體來說,正常情況下,其染色體的結(jié)構(gòu)和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下,染色體的結(jié)構(gòu)和數(shù)量均會(huì)發(fā)生改變,從而導(dǎo)致生物性狀的改變,這就屬于染色體變異。(二).把握重點(diǎn)、突破難點(diǎn)重點(diǎn)的把握:1、染色體結(jié)構(gòu)的變異播放影片:貓叫綜合征幼兒。讓學(xué)生觀察: 患兒哭聲輕、音調(diào)高,很像貓叫。教師補(bǔ)充: 患兒的征狀---兩眼較低、耳位低下,存在著嚴(yán)重的智力障礙。闡述病因---染色體片段缺失

各小組派代表匯報(bào)。4、教師提出問題組織學(xué)生討論:⑴要想了解更多的綠色食品,了解綠色食品的銷售情況,我們應(yīng)該怎么做?⑵要想了解廣大消費(fèi)者對(duì)綠色食品的態(tài)度,食用綠色食品的意義,是否懂得辨認(rèn)綠色食品,以及什么樣的人群對(duì)此知識(shí)最缺乏等,我們應(yīng)該怎么做?組織學(xué)生匯報(bào)交流。5、做個(gè)“綠色食品”廣告設(shè)計(jì)師。為你喜歡的綠色食品設(shè)計(jì)廣告語,每組推薦一個(gè)。6、讓學(xué)生了解綠色食品認(rèn)證程序。7、綠色食品打“假”隊(duì)員在行動(dòng)。8、向?qū)W生介紹生態(tài)綠色食品基地。三、活動(dòng)總結(jié):通過研究、探討,了解學(xué)生對(duì)綠色食品的態(tài)度。提問:民以食為天,吃,是一個(gè)大問題,如果你的爸爸媽媽讓你到超市買牛奶、方便面等,你會(huì)選擇什么樣的食品?為什么?希望通過今天的學(xué)習(xí),同學(xué)們能夠做到綠色消費(fèi),也希望你們向自己的家人、向周圍的了解學(xué)生對(duì)“無公害食品”、“有機(jī)食品”與“綠色食品”的認(rèn)識(shí)。

分析過焦作市的地理概況和產(chǎn)業(yè)優(yōu)勢(shì)后,就需要針對(duì)由于資源枯竭所帶來的問題提出合理化的建議。既然是談經(jīng)濟(jì)轉(zhuǎn)型,就應(yīng)該將話題的范圍明確在這一領(lǐng)域內(nèi)。通過材料3的相關(guān)內(nèi)容,我們了解到焦作市需要在產(chǎn)業(yè)結(jié)構(gòu)調(diào)整、培育新的優(yōu)勢(shì)產(chǎn)業(yè)、增強(qiáng)綜合競(jìng)爭(zhēng)力等三個(gè)整改方針上下功夫。因而引導(dǎo)學(xué)生針對(duì)優(yōu)勢(shì)與不足提出建議,以三個(gè)整改方針為基準(zhǔn),衡量建議的可行性是鍛煉學(xué)生解決此類問題的有效途徑。在此我將教會(huì)學(xué)生的是解決問題方法而非案例的內(nèi)容,正所謂“授之以魚,不如授之以漁”。接下來針對(duì)學(xué)生的建議和教材資料分析所羅列的10點(diǎn)整改思路,由學(xué)生自由發(fā)言提出看法,通過教師的指導(dǎo)和學(xué)生的討論,進(jìn)而確定經(jīng)濟(jì)轉(zhuǎn)型建議的具體方案。最后注意將建議與產(chǎn)業(yè)優(yōu)勢(shì)相對(duì)照,看建議是否都是圍繞著產(chǎn)業(yè)優(yōu)勢(shì)而提出的,這樣做會(huì)加深學(xué)生的印象,通過建議和優(yōu)勢(shì)的對(duì)應(yīng)關(guān)系,將不難找出此類問題的解題思路。

三、孟德爾遺傳規(guī)律的現(xiàn)代解釋①分離定律:在雜合體的細(xì)胞中,位于一對(duì)同源染色體上的等位基因,具有一定的獨(dú)立性;在減數(shù)分裂形成配子的過程中,等位基因隨同源染色體的分開而分離,獨(dú)立地隨配子遺傳給后代。②自由組合定律:位于非同源染色體上的非等位基因的分離或組合是互不干擾的;在減數(shù)分裂過程中,同源染色體的等位基因彼此分離的同時(shí),非同源染色體上的非等位基因自由組合??偨Y(jié):再次強(qiáng)調(diào)孟德爾遺傳定律的現(xiàn)代解釋課堂練習(xí):書本31頁6、教學(xué)反思:本節(jié)課設(shè)置了一系列問題情境,層層設(shè)問,在學(xué)生答問、質(zhì)疑、討論過程中讓學(xué)生建構(gòu)新概念和新的知識(shí)體系,并通過教師及時(shí)掌握反饋信息,適時(shí)點(diǎn)撥、調(diào)節(jié),讓學(xué)生在推理判斷中培養(yǎng)良好的思維習(xí)慣和對(duì)知識(shí)的遷移能力,而且通過留出一定的時(shí)間讓學(xué)生提問,體現(xiàn)了以學(xué)生為主體的思想。

Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.

In this class, I have 3 teaching aims, that is, knowledge aims, ability aims and emotion aims.1) Knowledge-Teach students new words and expressions, such as temporary, bleed,sprain choke, first aid, fall ill and so on.-Enable students to have a better understanding for some basic knowledge of first aid.2) Ability-Train students’ speaking, reading and writing abilities by different teaching activities, such as skimming, comprehending, team work, role play, retelling and writing.-Develop students’ reading strategy on how to move general idea to specific information.3) Emotion-Promote students’ awareness of giving first aid.- Cultivate students’ creativities.Then let’s come to my teaching methods and activities.III. Teaching methods and activities:To achieve different teaching aims, various kinds of teaching methods and activities will be adopted throughout this period, such as TBL (task-based learning), skimming, team work, brainstorm and others, which can offer students opportunities to fulfill tasks in which they can use language to achieve a specific outcome.IV. Teaching aids:Computer and blackboardV. Teaching important points:1) Make students have a clear mind for the structure of the text.2) Help students understand the theme of the text.VI. Teaching difficulties:1) So many new words may affect students’ understanding.2) How to get students to know about the functions of the skin and thecauses, characteristics and treatments for different degree burns,and the knowledge about giving first aid. VII. Blackboard design:

Textbook: Senior English for China (Book 4), by Liu Daoyi Time Allotment: 1 period (40 minutes)Date: March 20, 2014Teaching aids: blackboard, Multi-media, Power Point, chalk I. Text Analysis (教材分析)This unit is about body language, and the text selected in the reading part demonstrates the difference and similarity of body language in many parts of the world. Through learning this passage, students are required to raise their awareness of using body language in different parts of the world. As body language is closely related to our daily life, it is easy to arouse students’ interest in learning this text. Reading skills and speaking training are designed around the text.II. Teaching Objectives (教學(xué)目標(biāo))By the end of the lesson, students will be able to:1. Language Skill Objective(語言技能目標(biāo)): develop reading ability (skimming and scanning)as well as speaking ability.2. Cultural Knowledge Objective(文化知識(shí)目標(biāo)): know about the cultural differences of using body language.3. Affective Objective(情感目標(biāo)): increase students’ awareness of using body language correctly in different cultures. III.Teaching Focuses and Difficulties(教學(xué)重點(diǎn)和難點(diǎn))1. Teaching Focuses(教學(xué)重點(diǎn)): the difference and similarity of body language in many parts of the world.2. Teaching Difficulties(教學(xué)難點(diǎn)): develop students’ reading abilities of skimming and scanning and ask the students to show their opinions with fluent English.

通過寫文章梗概,培養(yǎng)學(xué)生綜合運(yùn)用語言的能力,學(xué)習(xí)用恰當(dāng)?shù)挠⒄Z描述科學(xué)家的故事。這是本課的教學(xué)難點(diǎn)。教師可以使用完形填空的方式來幫助學(xué)生整理語篇,從而來降低難度。本課的教學(xué)重點(diǎn)的突破方法是:在閱讀前,讓學(xué)生初步了解得出科學(xué)觀點(diǎn)所需要的基本程序,從而輕松而自然地導(dǎo)入文章的閱讀;在閱讀過程中,由易到難設(shè)計(jì)快速閱讀和精讀的問題,層層推進(jìn)各種閱讀活動(dòng),讓學(xué)生對(duì)閱讀內(nèi)容從整體感知到細(xì)節(jié)理解,最后深層讀懂整篇文章,同時(shí)加強(qiáng)閱讀策略的指導(dǎo),讓每個(gè)學(xué)生都主動(dòng)參與課堂教學(xué)活動(dòng),最終達(dá)到提高閱讀能力的目的。Step 4 Post-readingGroup Activities四人小組共同合作,在老師的適當(dāng)指導(dǎo)下,就以下2個(gè)問題展開討論,讓學(xué)生就所知、所學(xué)、所感和所想融入話題,然后抽若干同學(xué)代表作小組發(fā)言。1. What do you think about John Snow, and what should we learn from him?2. Cholera was 19th century disease, which two diseases are similar to cholera today? Why?

Good afternoon, everyone. It’s my great pleasure to be here sharing my lesson with you. The content of my lesson is Senior English for China Book5 Unit 3 Life in the Future. I’ll be ready to begin this lesson from six parts: Analysis of the teaching material, Analysis of the students, Teaching aims and important and difficult points, Teaching methods and aids, Teaching procedures, and Blackboard design. First, let me talk about the teaching material.Part 1 Analysis of the Teaching Material:This unit is about what human beings’ life will be like in about one thousand years. By studying of this unit, we’ll Enable the students to know the changes in humans’ life and some new inventions bringing about the change and develop the interest in science. This lesson plays an important part in the English teaching in this unit. This is an important lesson in Book Five. From this lesson, it starts asking the Ss to grasp contents of each passage. Therefore, this lesson is in the important position of the teaching material. If the Ss can learn it well, it will be helpful to make the Ss learn the rest of this unit.Part 2 Analysis of the SsAs Senior2 Ss, they are at different levels of English fluency, some of them have lost interest in English. So during the lesson, I arrange a variety of activities to let all of them join in to attract their interest and let them be confident and taste the joy of success.

今天我們來介紹一下必修五第四單元的授課方式。這個(gè)單元的題目是Making the news。應(yīng)該是學(xué)生比較感興趣的話題,學(xué)生往往對(duì)新聞工作充滿好奇,所以我們可以利用這個(gè)機(jī)會(huì)多設(shè)計(jì)一些師生互動(dòng)和學(xué)生互動(dòng),來激發(fā)起學(xué)習(xí)的積極性,提高學(xué)習(xí)效率。同時(shí)我們可以利用這個(gè)單元不僅幫助學(xué)生掌握語言知識(shí),培養(yǎng)語言能力,同時(shí)讓其了解新聞工作的重要性,培養(yǎng)起社會(huì)智能感。這個(gè)單元分為六個(gè)課時(shí),它的教學(xué)目標(biāo)是這樣的:語言目標(biāo)是掌握詞匯表中的常用單詞和短語,掌握倒裝句的一些基本用法。 技能目標(biāo)是能初步掌握約會(huì)的基本句型并在真實(shí)的場(chǎng)景下正確運(yùn)用。新聞報(bào)道類文章的寫作技能。采訪的基本規(guī)范和溝通技能。情感目標(biāo)是對(duì)新聞報(bào)道的客觀性和真實(shí)性有更好的理解。對(duì)新聞?dòng)浾叩穆殬I(yè)有更深入的了解,并能體會(huì)其工作的重要性。下面我們來介紹一下第一課時(shí)的授課方式,第一課的教學(xué)目標(biāo)是這樣的第一課時(shí)的教學(xué)目標(biāo)語言目標(biāo):單詞:Occupation, journalist, editor, photographer, curious, personality, enthusiasm

三、文本中的句子解決完畢,大家對(duì)文本內(nèi)容的理解更加深入了。請(qǐng)速度文本,思考:《論語》具體涉及了哪些方面的內(nèi)容,體現(xiàn)了孔子什么觀點(diǎn)?明確:主要有治學(xué)、從政、修身養(yǎng)性和交友治道等方面,體現(xiàn)了孔子“克己復(fù)禮”的思想。四、 教師引導(dǎo)學(xué)生討論: 如何評(píng)價(jià)孔子的言行和觀點(diǎn)?從古至今人們對(duì)孔子有哪些評(píng)價(jià)?明確:1、春秋戰(zhàn)國(guó)時(shí)代, 孔子門人及其后學(xué)者均推尊孔子。門人中以子貢為代表,他對(duì)孔子贊美備至,奉如天人,把孔子比擬為高天、日月、木鐸,凡人是永遠(yuǎn)不可企及的,認(rèn)為孔子是天生的圣人,“仰之彌高,鉆之彌堅(jiān)”。亞圣孟子認(rèn)為孔子所行的“圣人之道”是遍及自然界和社會(huì)的至高準(zhǔn)則。然而當(dāng)時(shí)民間一般看法認(rèn)為孔子是博學(xué)成名的大學(xué)者。

明確:(1)結(jié)繩記事說。原始記事的一種方法。人類在沒有發(fā)明文字或文字使用尚不普遍時(shí),常用在繩索或類似物件上打結(jié)的方法記錄數(shù)字,表達(dá)某種意思,用以傳達(dá)信息,處理事件。 (2)書畫說。(3)倉(cāng)頡造字說。中國(guó)自古就有倉(cāng)頡造字之說。文字的發(fā)明是人類發(fā)展史上一件石破天驚的大事,它將人們的思維、語言、經(jīng)驗(yàn)以及復(fù)雜的社會(huì)現(xiàn)象記錄下來,使文化得以傳播交流、世代傳承。2、漢字的形體:中華民族五千年的歷史中,漢字的演變,從甲骨文--金文--大篆--小篆--隸書--草書--楷書--行書,字形由象形到點(diǎn)橫豎撇捺的方塊字,經(jīng)歷了漫長(zhǎng)的歲月。其中凝聚著民族的智慧,也體現(xiàn)出漢字逐步完善的過程,凸顯其方方正正、四平八穩(wěn)的特點(diǎn)。漢字又是一種文化的體現(xiàn),那些經(jīng)過藝術(shù)處理的漢字或跳起了拉丁舞、有的如同酒醉的成龍打起了醉拳,更是讓我們感到的是在欣賞漢字在紙張上跳舞,所以:書法是“紙上的舞蹈”。請(qǐng)大家看到書上的相關(guān)內(nèi)容,注意每一種形體的漢字的載體是什么,其功能又有什么不一樣。

探究、討論、交流:1、包弟討人喜歡,作者卻不得不將它送走,為什么?2、送走包弟后,作者為什么先是感覺輕松,隨后覺得沉重?3、“您的小狗怎樣?”這句話反復(fù)出現(xiàn),有什么用意?4、“整整十三年零五個(gè)月過去了”“整整”一詞有什么作用?5、“滿園的創(chuàng)傷使我的心仿佛又給放在油鍋里熬煎”這句話如何理解?6、“我懷念包弟,我想向它表示歉意?!比绾卫斫??學(xué)生各抒己見后教師結(jié)合材料發(fā)表看法明確總結(jié)特別是最后一個(gè)問題得出作者這發(fā)之心底的語言,不僅僅是歉意,更是發(fā)自靈魂深處的懺悔!是對(duì)生命的尊重,是一個(gè)有良知的作家對(duì)反省歷史的呼號(hào)。第三環(huán)節(jié)“認(rèn)識(shí)你自己”——懺悔意識(shí)與我引導(dǎo)學(xué)生正視和反省成長(zhǎng)過程中曾犯下過錯(cuò)。并布置課后作業(yè):要求學(xué)生課后在本周隨筆中談反省懺悔后的感受。

【教學(xué)目標(biāo)】Ⅰ、學(xué)習(xí)理解詩歌語言的暗示性特質(zhì)。Ⅱ、根據(jù)詩歌語言的特質(zhì),進(jìn)行遷移,領(lǐng)略詩歌的精妙之處,給同學(xué)如何鑒賞詩歌提供實(shí)感。㈠、導(dǎo)入:各位同學(xué),有個(gè)成語叫"一字千金"。對(duì)我而言,第一次領(lǐng)略到一個(gè)字的分量,是在小學(xué)三年級(jí)的時(shí)候,一次作文評(píng)析課上。當(dāng)時(shí)我對(duì)自己的文章充滿了期待,希望能得到老師的贊賞。記得老師進(jìn)來后的第一句話是"有一篇文章,我就沖它用了一個(gè)字,我給它打95分。打這樣的高分,對(duì)我來說,是極為難得的。"同學(xué)都充滿了好奇,老師接著說"這個(gè)字就是一個(gè)'悟'字。我們的同學(xué)都說我學(xué)到了,我明白了,我懂得了一個(gè)道理,而這位同學(xué)卻用了一個(gè)'悟'字,難能可貴。"這篇文章不是我的,在羨慕的同時(shí),一個(gè)字在文章中的分量就深深的刻在了我的心上。文學(xué)作品中,一個(gè)字精妙與否,足以決定作品是流光溢彩,還是黯然失色。尤其是我們的古典詩詞,用簡(jiǎn)短的幾個(gè)字,造就的卻是豐富的情感與博大的意境。讀后滿口余香,卻是妙處難與君說。這跟詩歌的語言是密不可分的。今天,我們就通過《說"木葉"》一文,對(duì)中國(guó)古典詩詞語言特質(zhì)作一番探幽。
