在环节与环节的过度上,要注意自然流畅,是顺理成章的进入下一个步骤,而不是直接切入。

因为过渡语既能起到承上启下的作用,又能抓住学生的注意力。

通过完成1c的读后任务,进一步理解对话内容。

在完成该任务时,如果答案不能直接从课文中找出,要引导学生学会用自己的语言总结和归纳答案,允许有不同的表达方式。

以1c的第一题为例(WhatcausedMrs.Zhou’sproblem?

)简单的回答就是pollution。

如果要答案具体化,就必须先引导学生找出周夫人的问题,再找出原因,最后用自己的话归纳出答案(Thechemicalfactoriesproduceterriblegas,maketoomuchnoiseandpourwastewaterintorivers)。

学生能够正确提出问题,也是能力的体现。

教师需要引导学生,一步一步朝着正确答案去思考,可以运用课文中的文本语言,也可以拓展例句提供新的语境,还可以根据已学知识理解新知识(以短语“getapainin…”为例,pain是本课新单词,要理解短语的意思和掌握短语的用法就会比较难,因此,教师可以通过“Ihaveasorethroat”帮助学生理解意思。

用举例“Igetapaininmyleg”同时捂住左腿,帮助学生观察该短语的用法)。

 

课文朗读是培养学生的语感,训练语音语调的方法之一。

为了让学生目标性更强,更加严格的要求自己正确发音,学会合作,教师采用(以六人组为例)组内三人扮演一个角色,进行对话;并采用一些竞争机制,激发学生的斗志和参与课堂活动的热情,维护小组的集体荣誉感。

在角色扮演前,教师选择率先做好准备的小组,让他们选择任一小组进行挑战,胜利者将得到老师的礼物(或者积分),落后组再选一组,循环挑战;也可以另外选择两组进行两两PK。
