Buying fruit教学案例

教学目标:使学生能够理解运用“What are these?”、“What are those?”以及“How many kilos?”询问复数物品的名称和重量。
    教学重难点:“What are these?”、“What are those?”这两个句型在实际情境中的运用。
    课前准备:水果的单复数图片,实物,磁带,句型卡片,台秤,多媒体课件。
    Step 1.Warming-up
    (一)Greetings.
    (1) T: 分别出示单个的水果实物及相应的水果复数图片,以:“What’s this?”师生对话,并请学生将图片贴在墙上。
    T: Boys and girls, look! What’s this?
    S: It’s a banana/pear/apple/pineapple/orange/peach.
    (2) T:多媒体屏幕出示3A教材上的小韵文及图片:“They are all very good.” They’re all fruit. They are all very good. Now, let’s say the rhyme together.
    S:看屏幕集体读小韵文:They’re all very good
    (设计意图:与学生进行简单的日常交际用语的交流,让学生很快融入英语学习的氛围,运用旧知,链接新知,引入下一步的学习。)
    Step 2.Presentation and practice
    (一)学习“What are these?”
    1、 出示梨子图片,教师以“What are these?”向学生提问,引出句型教读。
    Drill: these; What are these?
    2、 师生对话,引出“pears”。
    S: What are these?
    T: They’re pears .
    3、 拿出课前准备的水果图片,操练句型:S1:What are these?
    S2:They’re oranges/….
    (设计意图:由单数过渡到复数,衔接自然)
    (二)学习“What are those?”、“grapes”
    1、指着墙上粘贴的水果图片,与学生对话。
    T:Look at the wall. What are those?
    S: They’re oranges/pears/apples.
    2、 多媒体分别出示模糊的葡萄图。T: What are those? S: They’re apples.在学生的应答之后,图片变清晰,教师以“Sorry, you’re wrong. They are not apples.”作应答。接着引导学生反问老师。T: What are those? You can use“What are those?”ask me.
    3、Drill: those;What are those?
    4、 师生对话:S:What are those?
    T:They’re grapes.
    5、学生连锁操练:S1:What are those?
    S2:They’re grapes.
    (三)Sing a song, 巩固所学句型
    1、 出示看图填空。T: Let’s do some exercises.
    2、指名看图做口头填空练习。
    What are these? They are      .                 
    What are those? They are        .               
    What are      ? They 
    What       ?            .
