Warm-up Preview | (a) Cheer up. (b)Chant together. (c)Let’s try | a)Ask and answer questions. T:What can you see in the chant? 复习 “rain, cloud, sun, sea” 引出 “water”,并提出现在某些地方水污染的情况。 | 利用chant和Let’s try的内容让学生复习雨、云、大海等现象的复习并引导新的问题让学生思考. | |
Presentation | a)利用水污染的图片倡议人们保护水源,引出本课的内容“水是怎样循环的” 。 b)Watch a story about the water cycle and answer some questions. | Watch the story and answer some questions. (1)Where does the rain come from? (2)Where does the cloud come from? 3)Where does the vapour come from? | 利用水污染的图片倡议人们保护水源,引出本课的内容“水是怎样循环的 | |
Practice | 1、Ask and answer the three questions in pairs, then check. 操练句型“Where does … come from? It comes from…” 2、Listen and answer. The vapour comes from the water. But how can the water become vapour? (听课文内容回答问题,引出句子“How can the water become vapour?”) Activities | 1、read the sentences together. 2、操练难点句型“How can the water become vapour? The sun shines and the water becomes vapour.” 3、Read“Let’s talk”together | 出现云、雨、蒸汽和太阳照射的图片,根据图片提问水循环过程。这个活动能集中学生的注意力,提起学生的兴趣,使他们能在水循环的整个过程自如运用 | |
Make a dialogue in pairs. (自由选择一个方框,并使用方框里的单词造对话,一颗星代表得一分。) a) 教师边提问边在黑板上逐个贴出雨、云、蒸汽和水的图片,引导学生运用”comes from”口述水循环过程。 | make a dialogue like this: A: Hello, Mr Black. B: Hello. A: Can I ask you some questions? B: Sure. A: Where does the vapour come from? B: It comes from the water in the river. A: Where does the rain come from? B: It comes from the clouds. A: Thank you. B: You’re welcome. | 这个活动已经有了一定的拓展,学生可以运用完整的对话进行交流。而且学生可以根据自己的水平选择不同难度的单词框做对话,这样可以照顾到不同水平的学生,做到教学真正面向全体学生 | ||
