Laura 原创初中一般现在时同步辅导教案.doc

课题: 备课人：Laura 课型： 备课时间: 科目： 本备课适合学生： 教学目标： 初一 一般现在时教学内容：一般现在时语法的完整版块 概念；句子构成（be动词和行为动词两种类型）；be动词类型的肯定，否定；行为动词类型的肯定，否定；行为动词第三人称单数的变化；特殊疑问句重点难点：行为动词；助动词；行为动词第三人称单数的变化教学策略与方法： 学生在初一一开学已经学习了be动词，可借助be动词句型引申学习行为动词。另，由于三单是重难点，将其放在后面的版块单独讲解，然后再对前面的否定和一般疑问环节加进三单的情况。教学过程设计：1. 一般现在时的概念例句：I am a student.He is very tall.They get up very early every morning.They play basketball on Sundays.The earth goes around the sun.总结：一般现在时表示经常性或习惯性的动作、现在的状态或主语具备的特征能力等。2. 一般现在时的构成根据谓语动词来分类，be动词和行为动词 （让学生根据板书的句子分类）2.1. be动词：主语+be(am ,is, are)+其它。如： I am a student.He is very tall.2.2. 行为动词：主语+行为动词(+其它)。如： You get up very early every morning.They play basketball on Sundays.3. 否定句及一般疑问句的转变 （构成是陈述语序的肯定句，那么其他如何转变）3.1. be动词结构的否定与一般疑问句，引导学生回忆所学be动词句型“年龄，身份，状态”还是看回例句 He is a tall. 改成否定： He isnt tall.= He is not tall. (be 后加not) 改成一般疑问句：Is he tall? 回答 Yes, he is./ No, he isnt.回忆be动词用法口诀：我用am 你用are，is连着他她它主语单数都用is，主语复数都用are变疑问，往前提，句末问号莫丢弃。 变否定，更容易，be后not莫忘记。疑问否定任你变，句首大写莫迟疑。3.2. 行为动词结构的否定与一般疑问句看回例句：They get up very early every morning.They play basketball on Sundays.问题：1.有无be动词，无！变成一般疑问句，能直接把行为动词get up往前提吗？不能！所以“求助” 于是助动词诞生了！加助动词构成一般疑问句即Do they get up early every morning? 按照be动词的否定和回答得出 Yes, they do./No, they dont. 其中缩略回答 No, they dont.其完整的句子就是 No, they dont get up very early every morning.马上让学生尝试转换例句2:They play basketball on Sundays.Do they play basketball on Sundays?Yes, they do. /No, they dont. They dont play basketball on Sundays.总结：两种结构的否定句和一般疑问句的变换方式是一样的，只是行为动词需要助动词进行帮助。3.3 行为动词第三人称单数的变化规则复习三单：不是你，不是我，they，的第三方he she it，及单数名字如Lingling. 一般情况下，直接加-s，如：cook-cooks, milk-milks2以s. x. sh. ch. o结尾，加-es，如：guess-guesses, wash-washes, watch-watches, go-goes “强烈的送气音”3以“辅音字母+y”结尾，变y为i, 再加-es，如：study-studies练习：写出下列动词的第三人称单数 drink _ go _ stay _ make _look _ have_ pass_carry _come_watch_ plant_ fly _study_ brush_ do_teach_所以出现三单主语时，其否定和一般疑问句所使用的助动词也要有第三人陈单数的概念，do+es does看例句：They play basketball on Sundays. 将主语变成HeHe plays basketball on Sundays.He doesnt play basketball on Sundays.Does he play basketball on Sundays?Yes, he does. / No, he doesnt.学生尝试 They get up very early every morning.将主语变成 SheShe gets up very early every morning.Does she get up very early every morning?Yes, she does./No, she doesnt.按照要求改写句子 1. Daniel watches TV every evening.(改为否定句)_ 2. I do my homework every day.(改为一般疑问句，并作否定回答) _ 3. She likes milk.(改为一般疑问句，并作肯定回答) _ 4. Amy likes playing computer games.(改为一般疑问句，并作否定回答) _ 5. We go to school every morning.(改为否定句)_ 3. 特殊疑问句：疑问词+一般疑问句。如：How does your father go to work?They usually go swimming every morning.确定用when, 原句改成一般疑问句：Do they usually go swimming every morning?When do they usually go swimming?（1）Sun Yang usually washes some clothes on Saturday. 否定句: _ 一般疑问句: _划线提问: _ （2）Mingming usually waters the flowers every day. 否定句: _ 一般疑问句: _划线提问 _ 5. 课后练习一、用括号内动词的适当形式填空。 1. He often _(have) dinner at home. 2. Daniel and Tommy _(be) in Class One. 3. We _(not watch) TV on Monday. 4. Nick _(not go) to the zoo on Sunday. 5. _ they _(like) the World Cup? 6. What _they often _(do) on Saturdays? 7. _ your parents _(read) newspapers every day? 8. The girl _(teach) us English on Sundays. 9.
