设置对话内容  完成语言教学任务

　　教师可以设计一项“购买所缺食品”的任务让学生来完成。

　　先让学生设计出所需的物品，完成下列表格：

THE FOOD AND DRINK

WE NEED

THE FOOD AND DRINK

WE HAVE

OUR SHOPPING LIST

根据上表，要求学生完成以下几个任务：

　　1）学生反复操练食品的名称。

　　2）用英语表达自己喜欢和不喜欢的食品。

　　3）谈谈自己拥有什么食品，缺少什么食品，要购买什么食品。

　　4）如何表达购买食品。

　　让学生自己依照上述内容，编写对话，并进行表演。然后教师可以让学生继续就购买所缺食品进行设计，设计去商店购物的对话，教师可以给出地点，购物时间，商店营业时间安排等事项，让学生就这些内容进行类似的对话表演。

读短文，编对话

　　组织学生阅读下面的短文，分为四个小组，每组阅读一段。让学生根据短文内容来编写对话。

Children of the World

　　My name is Sanjay．I live in a village in India．My family is very poor，so my brothers all go out to work． But I am lucky－I go to school．I get up early each morning and walk to the school．When it gets very hot，we have lessons outside in the shade（阴影）of a tree．

　　My name is Inga．I live in a small town in Sweden．The land is very flat（平坦的） here，so I like to go out on my bicycle．When it is snowy，I ski to school．We start lessons very early- at 8 o'clock！Once a week I have dancing lessons．I am also learning to play the violin．

　　My name is David．I live in a small town in Australia．We are a long way from the nearest（最近的，近的最高级）big city．All the same，there is plenty to do here． I go swimming and surfing in the sea－but not when here are jelly fish（水母，海蜇）around！I also like to play rugby and go fishing．The weather is always warm，and I wear shorts all year round．

　　My name is Mario．I live in a city in E1 Salvador．This is a very poor country．Our house is made of wood and metal sheets，and we have no bathroom．In the mornings，I work in a carpenter's shop．In the afternoon I go to school．After that，I feel very tired， but I still find time to fly my kite，or practise on my guitar．
