設置對話內容 完成語言教學任務
教師可以設計一項“購買所缺食品”的任務讓學生來完成。
先讓學生設計出所需的物品，完成下列表格：
THE FOOD AND DRINK WE NEED | THE FOOD AND DRINK WE HAVE | OUR SHOPPING LIST |
根據上表，要求學生完成以下幾個任務：
1）學生反復操練食品的名稱。
2）用英語表達自己喜歡和不喜歡的食品。
3）談談自己擁有什么食品，缺少什么食品，要購買什么食品。
4）如何表達購買食品。
讓學生自己依照上述內容，編寫對話，并進行表演。然后教師可以讓學生繼續就購買所缺食品進行設計，設計去商店購物的對話，教師可以給出地點，購物時間，商店營業時間安排等事項，讓學生就這些內容進行類似的對話表演。
讀短文，編對話
組織學生閱讀下面的短文，分為四個小組，每組閱讀一段。讓學生根據短文內容來編寫對話。
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（陰影）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 oclock！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，近的最高級）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 carpenters 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.
