设计意图：从学生生活中的琐事入手，使教学内容更加切近学生生活，激发学习兴趣，导入新课，学会利用情态助动词进行推理，激发他们更强的求知欲望，为下面的学习做铺垫。
创设不同的语境让学生学会运用不同的助动词进行推理通过提问，师生问答，学生自己探究，操练学习句型，加深学生对它的理解。陈述原因时，提高学生的语言表达能力。
创设语境，用图片教单词，吸引学生的注意力，直观形象。
对学生进行听力训练，培养技巧，在听中再次巩固所学知识。同时进行环保的教育。
巩固目标语言，检测语言使用的准确性。并能正确说出推理的依据。
目的在于运用不同图形的变化，最后形成一个书包，在形成的过程中运用could，might，must进行推理，激发学生的想象力，和求知的欲望，同时为2a，2b做铺垫。
预测听力信息，培养听力策略。让学生有目的带着问题听。训练和提高学生听力和理解能力，再次巩固新知识
让他们在听录音，思考，回答问题，找出推理的依据，培养学生的推理能力。
让学生带着问题看动画，带有目的性，更能让学生有强烈的情感体验，，并且直观形象。
回顾总结所学知识，加深理解和运用，培养学生的探究精神。
为学生创设语境，真实演绎本单元话题——推测，既让学生使用了目标语言，也能让学生体会到语言应用的意义。同时教育学生要自信。
进一步总结巩固语言点。

Teaching reflection
In this lesson, I design lots of activities that are close to students’ everyday life in order to make them be interested in English.The contents are easy.But during the class,I was moved by zhangYan’s answer.when we matched one thing with one reason,she said the toy truck must belong to Jane’s little brother because he was the only little kid at the picnic. As a student from Grade 7,it is not easy to do it like that.Later on ,other students said the sentences like her.but there are some mistakes.So I should show the structure on the screen,they can imitate it correctly and they can’t make mistakes like this.They can use the right structureto make sentences.On the other hand,when I extended 1b and mentioned the environment they could not understand it well.So I should pay more attention to the little details in the class. At the same time,I should pay attention to strengthening the cultivation of?students' learning?ability and skills in the future teaching. Let the students make the?transition? from pure knowledge?to the comprehensive ability?.?Only in this way,?our?class?is full of energy and the?teaching is effective.21世纪教育网版权所有
