2. 创设情景,为学生搭建语用平台,使学生运用语言真实交流。
教学难点:
语言must 和mustn’t 的理解与朗读以及在实际情境中正确运用。
四、课前准备
1.准备一盒火柴。
2.教师准备课件和单词卡。
五、教学过程
1. warm-up and review
T: good morning, boys and girls.
Ss: good morning, miss Sun.
T: How are you today?
Ss: I’m fine. thank you!
(走近个别学生与之问候,拉近距离,为本节课的开展做好情感、心理铺垫。)
2. presentation
T: First, look at me carefully. (教师手拿火柴,划开火柴,让学生感受火。接着,火柴伤到手指,引出单词match, fire,hurt.)
设计意图:让学生感受到火的存在及火的危害性,同时激发学生参与课堂活动的兴趣。提高注意力,为本课的学习做好了准备。
T: please look at this picture. what do you want to know when you see the fire? (图片出示火能伤人,也能烧毁一大片森林。鼓励学生根据图片给出的信息提出问题,老师可以随机板书到黑板上,如:Fire can hurt people, fire can burn down so many trees. (第一遍看完图片后,解决学生提出的问题,同时提问学生问题。What should we do in our life?)
T: I have a question, What should we do in our life?
(解决问题,让学生讨论并给出汉语答案。引导学生回答 We must be careful with fire.
T: OK, now. We know fire is dangerous. What do we know about fire safety? Let’s look at the pictures.(教师出示三张图片:1,在家中玩火。2.在森林里抽烟。3.在家里玩火柴。)
Ss: watch the pictures carefully.
T: Hello! Everyone. now ,let’s talk about the sentences.
设计意图: 初步感知、理解新知,策略性的处理认读句子的教学重难点。落实教学目标。
T: look! we mustn’t play with matches. We mustn’t play near fire. We mustn’t smoke in the forest.
(学生小组活动,利用新学习的句型自由问答 what must we do? what mustn’t we do? 并找同学展示。)
3. Practice and show.
T: boys and girls, you can know so many things. you’re great
.now let’s watch the tape.
SS: watch the tape and follow it.
(跟录音读---自由读-----分角色读。)
