朗讀(讀說思議練結合,培養(yǎng)學生語文綜合能力。) 1、學習第一小節(jié): (1)指名讀,回憶剛才摸鳥蛋的感覺(小小的、涼涼的)體會著讀一讀。 ?。?)比較“鳥蛋涼涼的”和“涼涼的鳥蛋”:你發(fā)現(xiàn)了什么?(引導學生發(fā)現(xiàn)這類詞語的特點:詞序不同,但表達的意思相同。)除了涼涼的鳥蛋還有什么是涼涼的? ?。?)你還能像這樣再說幾個嗎? (如果學生說不出來,教師可進行指導,把寫有“花兒、小草、柳枝、大海,紅紅的、綠綠的、軟軟的、藍藍的”的詞語卡分給學生,讓擁有不同詞語的學生去找朋友,再讓兩個朋友變換左右順序。) 2、學習第二小節(jié): (1)輕聲讀文,思考:你怎么知道兩只鳥蛋就是兩只小鳥? (2)出示小鳥破殼的圖片或課件,引導學生說一說?! 。?)啟發(fā)想象:鳥媽媽焦急不安是什么樣?你能表演一下嗎? 表演后試著把媽媽的語氣讀出來?! 。?)你還能用焦急不安說句話嗎?看誰說得和別人不一樣? 背誦(采用多種形式調動學生背誦積極性,幫助學生有意識地積累語言。) 練習有感情的背誦前兩個小節(jié)。
精讀課文,理解積累 1、同學們的字記的很好,課文也一定能讀出感情來?,F(xiàn)在就請同學們帶著自己的理解和感受,有感情地讀一遍課文,并自己喜歡的一段精讀?! ?、討論交流,指導朗讀 調整方案: 方案一:通過讀文你知道了什么?(這一問題較開放,如果學生已從整體上感知課文內(nèi)容,即可進入下一環(huán)節(jié)。如果學生回答只停留在零散的詞句上,就按方案二教學。) 方案二:小燕子、麻雀和黃鶯它們分別認為春雨是什么色的?他們?yōu)槭裁催@么認為?(板貼寫有字的小寫圖片和對應的顏色) 3、小組內(nèi)討論:a.如果分角色朗讀的話,該怎樣讀爭論的語法,朗讀好“不對”“不對,不對”“你們瞧”b.怎樣表現(xiàn)春雨小鳥和大自然?! ?、根據(jù)自己的理解感受小組內(nèi)分角色讀、表演讀?! ?、請一組同學配樂表演讀,學生評價 6、同學們春雨到底是什么顏色的呢?把你的想法說一說,畫一畫(自選粉筆板畫春雨) 7、指導積累。同學們讀得真有感情,現(xiàn)在請把你喜歡的詞句畫下來。
朗讀(多層次自主閱讀,拓展思維空間,提高閱讀質量。) 1、檢查讀。教師以開火車的形式讓學生按自然段讀課文,看誰讀得既正確又流利?! ?、指正讀。把你喜歡的小動物的話找出來讀一讀,教師隨機指導?! ?、想象讀。先聽范讀錄音,然后指名讀文,邊讀邊想象當時的情景。 4、分角色讀。教師指導學生研究討論每個角色的語氣怎樣讀,并嘗試給這些角色設計表情動作?! ∪纾核徆霉茫ㄆ婀值膯枺骸靶∥浵?,你怎么了?” 小螞蟻(揉肉眼睛,傷心的)說:“我不小心掉進池塘,上不了岸啦!” ?。ㄗ寣W生嘗試添加提示語,是一個大膽的嘗試。讓學生根據(jù)生活經(jīng)驗和對課文的理解,給“人物”設計表情動作,添加不同的語氣詞,使課文變成了童話劇。由于是自己創(chuàng)造的成果,學生會讀得有情有趣,有滋有味。但這種能力的培養(yǎng)不是一朝一夕的,教師要有意識的加以引導。)

三、教學建議第一課時:1. Lead in (Vocabulary)A) Before class, teacher should collect some pictures of working places. For example: Bank, TV Station, Restaurant, Police Station, Hospital ...B) In class, show students the pictures (PowerPoint, OHP). Ask students to tell the name of the working places and the name of the jobs.Shop assistant, doctor, actor, reporter, police office, waiter, bank clerk, studentC) Do exercise 1a and 3a.2. Bingo GameAsk groups of students to make up pairs of cards with a job on one and the related workplace on the other. For example, waiter / restaurant, teacher / school, doctor / hospital. Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3. Task OneA) Ask students to work in pairs and ask the partner what does he / she want to be in the future.e. g. :What do you / does he / does she want to be?I want to be a.Why?Because it's (adj).B) Vocabulary: Section B, 1a4.
