教学重难点

2.指示代词this,that,these,those的适当运用。
3.Howmuch引导的问句及回答,以及句中的主谓一致。
4.能够熟练运用购物用语进行购物的交际活动。
教学思路
本课时的重点是学习表示衣物、颜色、形状以及价格的词汇,在巩固运用Howmuch…?
句式对衣物的价格进行问答的基础上,进一步拓展了询问价格的简单句式,加入一些常见购物用语。
要求学生听懂购物场景下的简单对话,获取有关衣物和价格的关键信息,并能使用常见购物用语进行交际。
思路一:
通过图片的形式教学生表示形状的词汇,让学生直观感受词汇的音、形、义。
促进理解,加深记忆;然后通过实物展开练习。
思路二:
听力训练采用听前观察图片,简单描述,对图片整体感知,从而降低听力难度。
思路三:
设计购物情景,让学生运用所学购物用语模拟购物,激发学生参与热情,积极主动运用目标语言进行交际。
达到在用中学、学中用的教学目的。
教学准备
设计教学PPT,录音机,多媒体,制作3a和3c部分的插图和人物对话课件。

◆I’ll是I和will的缩写,用于一般将来时,表示动作将要发生。
take意为“买下”,相当于buy/get/have;口语中表示“买下”常用take。
