Divide students into four groups.Then ask students some questions: •What food would you choose if you are hungry?Why? •Do you think you have a balanced diet? •Do you think having a balanced diet is an important thing?Why or why not? Now please have a discussion. (The answers are open.) [设计意图]

通过PPT课件和图片提示,努力创造更加真实的语言交际情景,让学生围绕“食物”话题展开,进行讨论什么是均衡膳食。

StepⅡ.Presentation Read the text and find out some key phrases and sentences. Key phrases: be rich in…

be made of be popular in Western countries Key sentences: Here are the four food groups. They help you grow and stay healthy. Your body needs calcium to stay healthy. Actually,other foods like fish,eggs and beans have a lot of protein,too. A well-balanced diet includes foods from each food group. ☆教材解读☆

1.Here are the four food groups:

Here are…是一个倒装句型,意为“这些是……”,其中的be要根据be后的名词确定单复数,单数名词要用is;复数名词要用are。

Here is a card for you.这儿有你一张卡片。

Here are the problems they can’t solve. 这些是他们不能解决的问题。

2.Breakfast cereal is also made of different grains.

be made of意为“由……制成”,指用原材料制成东西后,从成品中还能看出原材料是什么(不改变本质,只改变形状)。

【拓展】

(1)be made from意为“由……制成”,表示原材料往往经过化学变化,从成品中已看不出原材料。

(2)be made in意为“在……被制造”,后面通常接地点名词,表示其产品的产地。

(3)be made by意为“由/被……制造”,后面接动词的执行者。

(4)be made into意为“被制成……”,主语是原材料,后面接成品。

3.Fruits and vegetables are also rich in vitamins,minerals and fibre.

be rich in表示“在……方面很富有,充裕”。

Vegetables are rich in vitamins. 蔬菜富含维生素。

4.They help you grow and stay healthy.

stay healthy,keep healthy,keep in good health都表示“保持健康”。stay healthy侧重某人一直处在一种健康的状态;keep healthy侧重在主观意愿上“保持健康”,特别是通过某种方式,如锻炼、运动、饮食等方面来保持健康。

5.Your body needs calcium to stay healthy.

to stay healthy在这里是动词不定式短语作目的状语。动词不定式短语作目的状语时,既可以放在句首,也可以放在句末,翻译时常译为“为了……”。

6.Milk,cheese and yogurt contain calcium.

contain为及物动词,意为“包含,含有”,不用于进行时。可表示包含事物的全部或部分,强调“整体中含有……,某物体中含有……,容器中有……”,是指包含的内容。

7.A well-balanced diet includes foods from each food group.

本句也可以写成A well-balanced diet contains/has foods from each food group. [设计意图]
