牛津小学英语4B Unit4 Buying fruit 篇1

  一、教材分析:

  本单元的核心教学内容是“认物”,主要学习句子what are these/ those? they’re… book 4a中已经出现what’s this/ that? it’s…句型。教学中教师可以采用以旧带新的方法,从单数句式引出复数句式,还可以通过单复数形式比较找出它们之间的区别。本单元出现了八个水果类单词,除了grapes是第一次出现以外,其余七种均在book 3a第三单元中出现过。本单元出现的是这些单词的复数形式,涉及到词形、读音的变化,是教学中的难点。教师可以对名词复数的词形和读音进行归类。教师在设计情境的时候,将book 3b里学过的在商店里购物的常用语can i help you? what would you like? how much is it/ are they? 与本单元how many kilos? these or those? 等紧密结合,让学生更熟练充分地操练对话,使学生有话可说。

  教学重点:

  1. 能听懂、会说、会读和会拼写单词buy, apples, oranges, bananas, peaches, grapes, pears, some.

  2. 能听懂、会说和会读日常交际用语can i help you? these or those?

  3. 能听懂、会说、会读和会写句型what are these/ those? they’re … how many kilos? …kilos, please.

  4. 会诵读歌谣<i like fruit>

  教学难点:

  1. 学生能在生活中用本单元句型英语正确地认物。

  2. 初步掌握名词复数的词形和读音的变化。

  3. 了解辅音字母组合th在单词中的两种不同读音。

  课时建议:4课时

  第一课时:教学b部分八个单词apples, oranges, bananas, peaches, grapes, pineapples, watermelons, pears. 利用水果实物图片,由单数句型what’s this/ that? it’s…引出句型what are these/those? they’re….

  第二课时:复习巩固b. c,创设购物的情境,学习d部分新句型how many kilos? …kilo(s), please.

  第三课时:创设情境,巩固c. d部分对话,学习a部分对话,综合运用句型,引出e部分的内容:these or those? the red/ big/small/…ones, please.

  第四课时:熟练掌握a. e对话内容,巩固本单元全部句型,完成f. g的游戏、诵读教学。教师要尽可能创设让学生感兴趣的情境,让学生通过各种感官“认物”,逐步培养学生的说话能力。在<i like fruit>小诗中,能让学生自己换词创诗歌,激发学生探究学习的兴趣。

  二、教学建议:

  1. 单词教学:本课的单词除了grapes以外,都是book 3a中学过的,并且也是以复数的形式出现,因此教师在free talk中用句型i like apples. what do you like? 复习导入。教师可以利用水果图片先复习apples, oranges, bananas, peaches, pineapples, watermelons, pears.然后教教grape:[great, tape], 造词组:big grapes, small grapes, many grapes, some grapes, how many grapes,渗透拓展purple grapes.教师必须将b部分八个单词全部板书,并且单复数用不同颜色的粉笔区分,让学生初步发现名词复数的变化规则以及发音,在学生自主发现的基础上,教师简要介绍名词复数形式的构成规则。由于本单元学习的水果单词较多,教师可以采用smell and touch, taste and guess, 我单你复,我复你单等游戏教学。结合g部分的rhyme,让学生利用所学的单词编成新的小诗,巩固单词发音的同时,能让学生更好的认识水果颜色、味道等方面的特征。

  2. 句型教学:

  a: what are these/ those? they’re…教师可以从book 4a中学过的句子what’s this/ that? it’s…入手,通过单复数比较自然过渡到复数句子。教师要注意this/ these, that/ those中th的正确发音。为了清楚地区分these和those,教师在教的时候要注意物品摆放的远近。问what are these?时,物品要放近处,问what are those时,物品要放远处。为了激发学生的兴趣,教师可以整合g部分1、2,通过感官来学习句型,还可以主语变换are they…? yes, they are. /no, they aren’t.让学生摸一摸,猜一猜,直到猜对为止。在巩固what are these/ those句型时,教师不必局限于水果类单词,还可以食品、饮料类的,尽可能让学生发挥运用语言的能力。

  b:how many kilos?... kilo(s), please.课前布置学生带好各种水果,上课时让他们放在课桌上。教师带一个天平秤,创设买卖水果的情境。教师可以当一个农民的形象,告诉学生今天将摆一个水果市场,举行“买水果”的活动,教学buying fruit。扩展组词buy books/ apples/ drinks…

  教师应简单说明fruit是“水果”的总称。教师示范先当农民,引出how many kilos?的句型,鼓励学生用以前学过的句型及用语来表演。

  e.g.  t: can i help you?

  s: i’d like some apples.

  t: how many kilos?

  s: two kilos, please.

  t: here you are.

  s: thank you. how much are they?

  t: they’re ten yuan.

  c: these or those? the red ones, please.教师事先准备好多种同类但大小、颜色不一的水果。在can i help you? i’d like some…的对话中引出these or those?并教师要手势或动作指示,引导学生用one的复数ones来回答。尽可能发挥the red/ green/ big/small ones.

  3、课文教学:

  课文是单词及句型的一个整合。学生在读熟、理解的基础上可进行角色扮演,然后再分组,安排话题让学生自由编造新的对话。各部分内容可以穿插运用。

  e.g (i)

  a: what about some pears?

  b: yes, please.

  a: how many kilos?

  b: three kilos, please.

  a: ok, here you are.

  b: thank you.

  a: not at all.

  (ii)

  a: can i help you?

  b: i’d like some…

  a: these or those?

  b: the big ones, please.

  a: how many kilos?

  b: one kilo, please. how much are they?

  a: six yuan, please.

  4、语音教学:

  语音教学在学生会读的基础上还要让学生自己探究举例。在讲解th的发音时,教师应板书这四个单词,让学生自己读,找出th的不同发音,举例:thank, bathroom, mouth, theatre, fourth, fifth, thing, something; their, these, the, that, this, father, mother, they, with

  5、诗歌教学:

  教师可以根据小诗的难易进行修改,在教会学生会读的基础上,让学生自己改编诗歌,激发学生自主探究学习的能力。

  教师还可以改编成:pears, bananas, pineapples.

  oranges, peaches, watermelons.

  these are grapes, those are grapes,

  they’re very nice.
