初中英语感叹句微课教案教学内容：初中英语感叹句教学目标：1了解What和How引导的两种感叹句的结构；2 掌握What和How引导的两种感叹句的用法；Teaching procedures:Step1 Lead in定义：表示喜、怒、乐等强烈感情时用感叹句，句尾通常用感叹号。种类：感叹句分为两种：一种以what引导，一种以how引导。 What a clever boy he is！How clever the boy is！Step2 Presentation一 、由What构成的感叹句1.What + a/an + 形容词 + 单数可数名词 + (主语 + 谓语)！”或“What + 不可数名词！ What a clever boy (he is)!（他是）多么聪明的孩子呀！ What fun!多好玩呀！ What a pity!多可惜呀2.What + 形容词 + 复数可数名词 + （主语 + 谓语）！ What beautiful flowers (they are)!3.What + 形容词 + 不可数名词 + （主语 + 谓语）！ What fine weather (it is)!二 、由How构成的感叹句1. How + 形容词 + a/an +单数可数名词 + （主语 + 谓语） +！How clever a boy he is!他多么聪明的男孩！2.How + 形容词 + 主语 + 谓语！How beautiful the girl is!那位姑娘多么漂亮呀！3.How + 副词 + 主语 + 谓语！How fast he runs! 他跑得多么快呀4.How + 主语 + 谓语！How time flies!时间过得真快呀！三、陈述句变为感叹句的方法把一个陈述句变为感叹句时，常使用“一分二加三换位四去掉”的方法。具体步骤为： 第一步：“一分”，即在谓语动词后面划一双竖线，使句子分为两部分。如：He is a very honest boy.他是一个诚实的孩子。Li Lei works very hard.李雷学习很刻苦。第二步：“二加”即如果第二部分的中心词是名词，就加上what；如果是形容词或副词，就加上how.如：He is (what) a very honest boy.Li Lei works(how) very hard.第三步：“三换位”即把第一部分与第二部分互换位置，句号换位感叹号。如：What a very honest boy he is!How very hard Li Lei works!第四步：“四去掉”即原陈述句中含有very, too等程度副词时，在变成感叹句时要去掉。以上两个句子就应该变为以下形式：What an honest boy he is!How hard Li Lei works!Step 3 Summary 感叹句记忆口诀感叹句，并不难，what与how应在前。 形容词、副词跟着how，what后面名词连。 名词若是可数单，前带冠词a或an。 主语、谓语放后面，省略它们也常见Step 4. 看我七十二变1.The cat is cute.How _ the cat is !T2.he pandas are lovely.How _ the pandas are !3.She swims wonderfully.How _ she swims!4.He runs fast.How _ he runs!5.She is a pretty girl.How _the girl is!a girl she is!Step 5 一What 与How 大转换1.
