4B《Unit 4 Buying fruit》教學案例及反思

課題內容：《unit 4 buying fruit》第一課時
教學目標：使學生能夠理解運用“what are these?”、“what are those?”以及“how many kilos?”詢問復數物品的名稱和重量。
教學重難點：“what are these?”、“what are those?”這兩個句型在實際情境中的運用。
課前準備：水果的單復數圖片，實物，磁帶，句型卡片，臺秤，多媒體課件。
step 1.warming-up
（一）greetings.
(1) t: 分別出示單個的水果實物及相應的水果復數圖片，以：“what’s this?”師生對話，并請學生將圖片貼在墻上。
t: boys and girls, look! what’s this?
s: it’s a banana/pear/apple/pineapple/orange/peach.
(2) t：多媒體屏幕出示3a教材上的小韻文及圖片：“they are all very good.” they’re all fruit. they are all very good. now, let’s say the rhyme together.
s：看屏幕集體讀小韻文：they’re all very good
（設計意圖：與學生進行簡單的日常交際用語的交流，讓學生很快融入英語學習的氛圍，運用舊知，鏈接新知，引入下一步的學習。）
step 2.presentation and practice
（一）學習“what are these?”
1、 出示梨子圖片，教師以“what are these?”向學生提問，引出句型教讀。
drill: these; what are these?
2、 師生對話，引出“pears”。
s: what are these?
t: they’re pears .
3、 拿出課前準備的水果圖片，操練句型：s1：what are these?
s2：they’re oranges/….
（設計意圖：由單數過渡到復數，銜接自然）
（二）學習“what are those?”、“grapes”
1、指著墻上粘貼的水果圖片，與學生對話。
t：look at the wall. what are those?
s: they’re oranges/pears/apples.
2、 多媒體分別出示模糊的葡萄圖。t: what are those? s: they’re apples.在學生的應答之后，圖片變清晰，教師以“sorry, you’re wrong. they are not apples.”作應答。接著引導學生反問老師。t: what are those? you can use“what are those?”ask me.
3、drill: those；what are those?
4、 師生對話：s：what are those?
t：they’re grapes.
5、學生連鎖操練：s1：what are those?
s2：they’re grapes.
（三）sing a song, 鞏固所學句型
1、 出示看圖填空。t: let’s do some exercises.
2、指名看圖做口頭填空練習。
what are these? they are      .                 
what are those? they are        .               
what are      ? they
what       ?            .              
3、t：now, let’s have a rest and sing a song“what are those?”（就剛才的口頭練習配上《兩只老虎》的旋律）
(設計意圖：歌曲是學生喜歡的一種學習英語的方式，便于學生記憶。)
