设置场景，实现情景教学
教师可以根据第90课第二部分的内容(JOY失足落水，范文，SMITH夫人救女儿)设计一项报道“救出落水儿童” 实际任务：
1)教师设定儿童落水地点和事件经过。
2)教师画出描述儿童落水并被营救的现场“照片”数张。
3)教师分别为各个小组分发打乱次序的现场“照片”。
4)教师向各个小组交代任务：用英语为各张“照片”写说明，以便发给《中国日报》。
5)学生根据交代的任务安排好事件发生的次序。
6)学生讨论对各张“照片”的英语措辞。
7)学生合作完成此项任务。
8)各小组之间互相进行相互评价，选出最好的说明交代《中国日报》。
9)教师进行整体评价。
在小组活动中教师要引导学生尽量使用有限的英语进行交流。
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。
