4B Unit4 Buying fruit

設計理念：英語課程的學習，不但是讓學生在學習英語的過程中，逐步掌握英語知識和技能，提高語言運用能力；更是讓學生在學習的過程中感受英語的魅力，開發學生的思維能力，磨礪學生的意志，拓展學生的情操，發展學生的個性。教師在教學過程中要關注每一位學生的情感，激發學生的學習興趣，因此要滲透新課標理念，優化教學結構。體驗生活，合作交流，優化教學，激發興趣，樹立信心，勇于創新。
一、教學目標  （teaching aims）
1、能聽懂、會讀、會說句型：(three-skilled sentences)
  ①what are these/those?
  they're……
  ②i'd like some……,please.
how many kilos?
……kilo(s),please.
here you are.
2、能在具體的情景中用所學的對話進行對話。
(can make dialogues with the learned dialogues in the true envirenment)
二、教學重點和難點(teaching emphasis and difficulties)
能夠熟練地掌握對話，并能在實際中運用所學對話。(can grasp the dialogues freely and use them in the daily dialogues)
三、教具準備(teaching tools)
多媒體課件(cai)、錄音機(taperecorder)、水果(fruits)
現在的英語教學目標強調了學生的興趣和經驗，結合學生實際，貼近他們的生活，重視學生的真實情。
四、教學過程(teaching process)
step1、greetings(good morning/afternoon)
      (how are you?/what's your job?……)
step2、warming up(chant)
    apples,apples,i like apples.
    oranges,oranges,i like oranges.
每節課的開頭一開始就要吸引學生的注意力，調動他們的興趣，這樣容易開展緊接著的內容。
step3、presentation
⑴cai(show the students a bridge of fruits,a tiger wants to go through the bridge,but he must speak out the names of the fruits,can you help him)
ask students to speak out the names of fruits."apples,oranges……"
⑵lead out and teach "what are these/those? they are ……"
first,task:what are these/those?
       ss:they're……
(cai game:guessing
show ss the half of the fruits pictures,the ss guess out their names,the winner can get a star.)
游戲、競賽刺激而又有趣，活潑生動的畫面能吸引學生的注意力，符合兒童的認知特點，迎合他們的需求，以這樣的方式既活躍了氣氛，又復習了舊識，為新知識的導入作好充分準備。
step4.new teaching
a.⑴teach sentences:what are these/those?they're……
(teach them during the game)
⑵practice this dialogue
①first read after t,then in pairs/groups/freely.
②act out this dialogue.
⑶game:make dialogues in the limited time.
(cai,show a clock ,and the pictures of fruits,make dialogues according to the picture quickly.the time is a half minute.)
eg:s1:what are these?
   s2:they're apples.
   s3:what are these?
   s4:they're bananas.……
(we can see which group can make more dialogues in the time.)
在教學過程中，充分把握時機，通過多媒體演示加大學生口頭練習的密度，將句型熟練操練，通過多種形式避免機械，也符合認知規律。
