五年級上冊第四單元《Let＇s talk》導學案

2. presentation and practice
最后在大屏幕中出現一張被遮蓋住的人物圖片。
t: please look at this picture. there is something that you can’t see. what do you want to know when you see the picture?
(鼓勵學生根據圖片給出的信息提出問題，老師可以隨機板書到黑板上，如：who is she? where is she?...)
t: here are your questions. now let’s watch the video and find the answers.
watch the video.
(第一遍看完光盤后，解決學生提出的問題，同時課件中被遮蓋的部分被打開，呈現陳潔做家務的畫面。)
t: i have a question, too. is chen jie helpful at home?(課件中出現老師提出的一個新的問題，讓學生帶著問題看第二遍光盤。課件中出現問題的時候，教師出示單詞卡helpful并領讀單詞和問句。)
watch the video again.
(看完第二遍光盤，解決問題，引導學生回答yes, she is. 當學生回答完此問題后老師再進一步提問：how do you know that?)
t: this time take out your books and listen to the tape. please underline the key sentences.
listen to the tape.
(讓學生專心聽，并且畫出重點句子。讓學生讀出重點句子的同時，教師板書 what can you do? i can sweep the floor. i can cook the meals.)
設計意圖: 初步感知、理解新知，策略性的處理認讀句子的教學重難點。落實教學目標一。
t: look! chen jie can sweep the floor and cook the meals at home. how about you and your classmates? ask each other.
(學生小組活動，利用新學習的句型自由問答 what can you do? i can…并找同學展示。)
t: boys and girls, you can do so many things. you’re helpful! now let’s listen to the tape.
listen to the tape and follow it.
(跟錄音讀---自由讀-----分角色讀。)
設計意圖: 充分的感知和必要的練習相結合，策略性的處理朗讀、運用功能句的教學重難點，內化所學知識。落實教學目標二、三。
3.consolidation and extension
t: chen jie can sweep the floor and cook the meals at home. you can also help your mothers do housework. you are helpful! how about them? now let’s guess what she/he/they can do?
(課件中呈現一組半遮蓋的圖片，讓學生利用新學習的句子what can he/she/they do? he /she / they can… 通過猜謎的形式，讓學生進一步運用所學句型來提問回答，既激發了興趣又練習了新知。鞏固教學目標二。)
t:（猜謎活動結束后老師指著課件上的一些圖片說）look！they can dance. he can play basketball. how about you and your classmates? what other things can you do?
(小組活動，讓學生相互詢問除了家務彼此還能做哪些事情。并在課件中提示學生注意替換課文中的重點句子，并關注對話的語篇詞匯。）
t: boys and girls, all of you are great! today i bring you a lot of friends. look! they are top ten young pionners of our school. they can do many things.(看課件中的十佳少先隊員圖片)
i invite two of them here. welcome!(請兩名十佳隊員上臺)
you can talk with them face to face. first, please think what you want to know about them. you can write down if necessary.（學生先思考可以提問哪些問題，接下來采訪現場的十佳隊員。）
