Lesson 45-46 教学设计方案

（两课时）

一．教学目的

　　1．复习、巩固第十一单元的There be句型。

　　2．掌握四会单词和词组child/ children, man/ men, woman/ women, at work/ at home/ at school要掌握读音，写法和用法。

　　3．教学There be的疑问形式：Is there a cat in the bee？及其肯定、否定回答。

　　4．巩固There be句型及其特殊形式How many…are there?

二．重难点

　　1．名词复数的不规则变化，如：man – men  woman – women   child – children 要求学生读准、写准、用准。

　　2．How many…？句型中How many接可数名词复数的用法。

　　3．掌握、运用There be句型的肯定形式与疑问形式的转换，并会作肯定与否定回答。

三．学法引导

　　1．教师教法：利用实物、挂图复习句型What’s…? There is a…/ There are some…利用幻灯片、图画教学名词的复数形式。围绕教室的实物教学Is there…？句型，提问Is there a book on the desk?帮助学生做出肯定回答：Yes，there is．再举几个应用肯定回答的实物，然后让学生两人一组一问一答进行练习。待到学生熟练，再教学Is there a book in the desk？帮助学生做出否定回答：No，there isn’t．再举出几个应用否定回答的实物，帮助学生做出否定回答，然后成组练习。

　　2．学生学法：仔细研究第一部分的词组，可以看出名词复数的变化规律，一般的名词在词后加-s，但有些名词是特殊情况，像child, man, woman这些词需要单独记忆。生活中可以为我们提供很多关于数量问答的情景，例如在你们班上有多少同学，在你的铅笔盒中有几支笔，等等，可以拿出这些东西，在同学之间做问答练习，巩固所学句型。为了练习句型There be的一般疑问句，请大家按照提示就教室里的东西进行问答。

四．教具

　　录音机、挂图、投影片、（微机）书、笔、尺等实物。
