陈述句与一般疑问句教案

陈述句与一般疑问句教案一、教学目的：了解陈述句与疑问句的概念，掌握这两种句型，能够将这两种句型进行相互的转换二、教学重点难点：陈述句与一般疑问句的转换三、教学过程（一）、引入看两个话：A 我今年17岁。B你今年17岁吗？回答是或不是引出陈述句和一般疑问句概念（二）、讲新课1、接着引入，讲陈述句概念（1）陈述句是用来说明事实的句子。它的后面用句号表示，语调一般是平的。有的陈述句表示肯定的语气，比如例1。还有像“小树长高了。”有的陈述句表示否定的语气，如“他没有参加小组会。”“我不认识这位老师。”有的陈述句用双重否定的形式表示肯定的语气，如“社会主义的物质文明与精神文明非搞好不可。”“乡亲们没有不夸雨来聪明的。”（2）疑问句是用来提出问题的句子，句末用问号表示。用be或助动词置于句首，并以“Yes，”，或“No，”回答的问句称为一般疑问（3）句型结构陈述句：主语谓语(be 动词/行为动词/情态动词).顺便讲什么是行为动词一般疑问句：be 动词/助动词/情态动词主语 顺便讲什么是助动词2、举例(1)陈述句I am seventeen. You are old. He is happy. She is young. It is rain.I like to play football toady. He go to school on foot.(2)一般疑问句Are you seventeen? Are you old? Is he happy? Is she young? Is it rain?Do you like to play football today? Dose he go to school on foot?重点(3)陈述句与一般疑问句的转换规则：A谓语是be动词：一般把be提前，句末加一个问号。B谓语是行为动词，直接在句首加一个助动词就可以，第一二人称（I you they ）开头用do ,第三人称（he she it ）用dose ，把主语后面的动词变为动词原型，句末加问号。注意：I 必需变成you 回头看前面的例子（三）、课堂练习陈述句变一般疑问句练习1 老师做1.
