教学目标

重点、难点 考点及考试要求 教学内容 知识框架

一、动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。 1、大多数动词在词尾加“S”在清辅音后发音为[s]，在浊辅音及元音后发音为 [z]。如： ①stop－stops [s] ; make－makes [s] ②read－reads [z] ; play－plays [z] 2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz] 如： fly－flies [z]； carry－carries [z] study－studies [z]; worry－worries 3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为[iz] 如： teach－teaches [iz]; watch－

watches [iz] 4、以“o”结尾的动词，加“es”，读[z] 如： go－goes [z] do－does [z] 下面几个动词变为单数时， 原词的元音部分的发音发生了较大的变化，请注意记忆。 如： 1、do [du:]－does [dz] 2、say [sei]－says [sez] 以不发音字母“e”结尾的开音节词，如果尾音是[s]，[z]时，加“s”后字母“e”发音， 与所加“s” 一起读做[iz]。 如： close－closes [iz] 二、对比词形变化中原词词尾变化之异同： 变“y”为“i”现象 双写最后辅音字母现象 例词： ①baby－babies ②carry－carries ③study－studying be动词包括：am， is， are。第三人称单数用 is； 过去式为 was；复数用are，过去式为were. 【一般现在时中的动词第三人称单数形式】在一般现在时

中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下：一、人称代词he, she, it是第三人称单数。如：He likes watching TV. 他喜欢看电视。She has lunch at twelve. 她十二点吃午餐。It looks like a cat. 它看起来像只猫。二、单个人名、地名或称呼作主语；是第三人称单数。如：①Han Mei looks like her mother. 韩梅看起来像她的母亲。②Beijing is in China. 北京在中国。③Uncle Wang often makes cakes. 王叔叔经常做蛋糕。三、单数可数名词或\"this / that / the+单数可数名词\"作主语时，是第三人称单数。如：①A horse is a useful animal. 马是有用的动物。②This book is yours. 这本书是你的。③That car is red. 那辆小汽车是红色的。④The cat is Lucy's. 这只猫是露茜的。四、不定代词someone, somebody, nobody, everything, something等及指示代词this,that作主语时，是第三人称单数。如：①Everyone is here. 大家到齐了。②There is something wrong with the watch. 这块手表有毛病。③This is a pen. 这是一支钢笔。④That is an eraser. 那是一块橡皮擦。五、不可数名词作主语时为第三人称单数。如：①The milk is in the glass. 牛奶在玻璃杯里。②The bread is very small. 那面包很小。六、当数字或字母作主语时，看作第三人称单数。如：①\"6\" is a lucky number. \"6\"是个吉利数字。②\"I\" is a letter. \"I\"是个字母。 练习设计 随堂练习设计
