Unit3 第1课时教学设计

一、板块介绍

本板块的课文包括三段内容。前两段以第三人称的叙述方式，对比介绍了Mike和Yang Ling的日常饮食习惯，第三段则呈现了健康饮食金字塔和一个问题，引发学生思考。教师可要求学生根据健康饮食金字塔，分析Mike和Yang Ling的日常饮食习惯是否健康，同时反思自身的日常饮食习惯是否健康。 二、教学目标

1、能听懂、会说、会读、会写healthy, diet, a little, a few, at a time。 2、能听懂、会说、会读Story time中的故事。 三、教学重难点

1、句型：… eat/drink a lot of/a little/a few … … have some …

2、词汇：healthy, diet, a little, a few, at a time. 四、教学过程

Step 1: Warm-up/Lead-in

教师和学生进行问答活动，要求他们说一说自己喜欢和不喜欢的食物，然后提出均衡饮食的问题，引发学生思考，导入本单元话题。教师可以呈现一些食物的图片，供学生选择回答。如： T: What’s your favourite food? S1: My favourite food is chocolate. T: What food do you like? S2: I like hamburgers and chips. T: What about you? S3: I like apples. S4: I like meat and fish. ...

T: What do you like drinking? S5: I like drinking juice. S6: I like drinking cola. ...

T: Can we eat a lot of hamburgers or chips? Can we eat a lot of cakes or ice cream? What food should we eat more? What food should we eat less? 2. 唱诵歌谣，导入词汇

教师和学生一起再读四年级上册Unit 6 (At the snack bar)的歌谣What would you like? 然后出示课前准备好的食物图片，和学生进行角色扮演的游戏，询问他们想吃的食物，复习词汇some。如：

T: Welcome to my restaurant/snack bar. What would you like? S1: I’d like some noodles and a glass of orange juice. S2: I’d like a hamburger and a glass of milk.

S3: I’d like some rice, some vegetables and some meat/fish. ...

3. 做游戏，归类词汇

教师可以利用课件，和学生一起玩“摘苹果”的游戏，复习有关食物和饮料的词 汇，并分组为可数名词和不可数名词。课件中呈现一棵苹果树，树上挂着许多苹 果，苹果上显示食物和饮料的词汇。树下放有两个篮子，分别标注可数名词和不可数名词。教师可以先要求学生朗读词汇，如cake，hamburger, bread, rice, egg, fish, meat, water, milk, ice cream, sandwich, vegetable, potato, tomato, juice等。学生在朗 读的同时将这些单词（苹果）放到相应的篮子里。 Step 2: Presentation & Practice Story time

1. 利用图片，教授目标词汇

教师利用课件呈现四组图片，通过比较的方法教授目标词汇a lot of, some, a little 和a few。教师可以先讲解它们在意思上的区别，然后再介绍它们如何与可数名词和不可数名词搭配。如：

第一组：a lot of eggs (一篮子蛋)，some eggs (半篮子蛋)，a few eggs (几个蛋) 第二组：a lot of apples (一篮子苹果)，some apples (半篮子苹果)，a few apples (几个苹果)

第三组：a lot of cola (一大瓶可乐)，some cola (半瓶可乐)，a little cola (小半瓶可乐)

第四组：a lot of rice (一大碗米饭)，some rice (半碗米饭)，a little rice (只能覆盖碗底的米饭)

2. 游戏活动，操练目标词汇

教师通过课件开展“连连看”的游戏，要求学生将a little和a few同若干食物（包括可数名词和不可数名词）和饮料图片匹配，然后说出相应的短语或一个完整的句子。

3. 问答活动，操练目标词汇

教师安排学生完成学生用书第34页Checkout time中的Ask and answer，要求他们两人一组，用there be句型结合some, any, a little, a few, a lot of进行问答活动。教师也可以要求学生独立完成描述图片的任务。如：

S: There are a lot of vegetables on the table. There are some green vegetables, a few potatoes and a few tomatoes. There’s a lot of/a big bottle of cola. There’s some meat. There’s a fish and a few eggs. There’s some rice and some juice too. 4. 问答活动，介绍日常三餐饮食

教师展示一张日常饮食表格，要求学生填入自己日常三餐的食物，然后用a lot of, some, a little, a few和句型 I have... for breakfast/lunch/dinner.作介绍。教师在学生完成表格后，安排他们小组活动，互相介绍自己的一日三餐食物。教师也可以要求学生在表达的时候灵活运用always, usually, often, sometimes等频率副词。如：

My diet Name Breakfast some bread … some milk an egg Lunch a lot of rice some vegetables a little meat an apple Dinner a little rice some meat a lot of fruit some ice cream S: I usually have some bread and some milk for breakfast. Sometimes, I eat an egg too. I always have a lot of rice for lunch. I also eat some vegetables and a little meat. I always have an apple after lunch. For dinner, I usually have a little rice, some meat and a lot of fruit. Sometimes, I eat some ice cream after dinner. 5. 看图讨论，理解健康饮食
