2．播放Read a story的录音，学生跟读课文。然后出示Read a story后续练习的句子，让学生结对完成排序练习。
3．根据故事，在黑板上画出海、山、太阳、云、大树等，构成一幅水循环图。让学生根据课文内容在图中加入箭头，并以第一人称说出小水滴的经历。
S: Hi, I'm Little Water Drop. I live in the sea. I want to go up to the sky. The sun shines. I get hot and go up and up. I'm in a cloud now. The wind comes. I fly over rivers and mountains. I see some trees. They're thirsty. I come down to the ground. I'm rainwater now. A tree drinks me. I'm in a tree now.
4．鼓励学生根据故事，圆出水的循环（The water cycle），可做成海报或多媒体。让学生分组展示出来。可使用下面一些句子。
The water rises to the sky.
The water becomes clouds.
It rains. The water comes down as rainwater. It is very cold. The water comes down as snow.
Ⅲ. Post-task activities
1．安排学生分组演出课本剧。
2．首先，教师以“金字塔”（Pyramid）的活动形式（底层从全体学生的个体思考，即每个人的意见开始；经过交流，合并相同、相近的意见；意见逐步集中，一直到顶层，即达成一致的认识。）组织学生讨论，完成《练习册》Task中的Think and discuss，讨论水的来源有哪些，教师根据学生的讨论在黑板上有选择地记录。接着，请学生用黑板上的短语来回答Where does water come from?
然后请学生结对子，共同完成Look and order部分，请个别学生试着说一说。
S: It rains. The raindrops fall into the river. The water in the river goes into a factory. In the factory, people make the water clean. The water then goes to homes through pipes. Finally, water comes out from the tap.
最后作为回家作业，请学生完成Think and write。
