一般现在时动词第三人称单数变化规则讲义与试题.doc

一般现在时、第三人称单数动词变化规则一、概述一般现在时的概念和用法：（1）表示现阶段经常、反复、习惯性的动作;（2）表示目前的状况；（3）表示自然界的客观真理。二、一般现在时的结构时态的结构指的是动词的变化形式。一般现在时间有两种结构，一种是动词原形，用于主语为非第三人称时的情况；另一种为动词的第三人称单数形式，用于主语为第三人称时的情况。Eg1. We often get up early in the morning.Eg2. My father often gets up early in the morning.三、谈谈“主语为三单，其后动词s添”在一般现在时中，当主语为第三人称单数时，谓语动词要用第三人称单数形式。可以简单叙述为“主语为三单，其后动词s添”。何谓第三人称单数？用一句话概括就是“非你、非我、非复数”，如he, she, it, my father, my mother, my sister, our English teacher, Tom, Mike, Liu Jia, China, my book, etc.Eg3.He sometimes goes to school by bike.Eg4.My father works in the hospital as a doctor.四、 一般现在时的肯定句中，主语为第三人称单数的动词变化主要体现在词尾的变化上，其规律为：（与名词变成复数的变法大致相同。）规则原形第三人称单数形式1、一般情况下，直接在动词词尾+sgettakeplaygetstakesplays2、以s, x, sh, ch, o结尾的动词，在词尾+ esguessfixfinishteachgo和doguessesfixesfinishesteachesgoes和does3、以辅音字母+ y 结尾的动词，先把y变为i，再加esstudytryflycarryworrystudiestriesfliescarriesworries4、不规则动词（特殊情况）havebehasis五、一般现在时的句子转换（1） 当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成一般疑问句;在be动词或情态动词后面加not变成否定句.例：陈述句：She is a student.一般疑问句 Is she a student?否定句 She is not a student.陈述句：I can swim.一般疑问句 Can you swim否定句 I can not swim.（2） 当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does（单数she,he,it）变成一般疑问句；在主语后谓语动词前加助动词dont（I,you,以及复数), doesnt（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。例：陈述句：We get up at 7:00 every morning.一般疑问句Do you get up at 7:00 every morning? 否定句We dont get up at 7:00 every morning.陈述句：She has a little brother.一般疑问句 Does she have a little brother? 否定句 She doesnt have a little brother.哪些主语是第三人称单数？1、 人称代词he, she, it；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。2、单个人名、地名或称呼作主语；是第三人称单数。如：Han Mei looks like her mother. 韩梅看起来像她的母亲。Beijing is in China. 北京在中国。Uncle Wang often makes cakes. 王叔叔经常做蛋糕。3、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；A horse is a useful animal. 马是有用的动物。This book is yours. 这本书是你的。That car is red. 那辆小汽车是红色的。The cat is Lucys. 只猫是露茜的。4、不可数名词作主语时为第三人称单数。如：The milk is in the glass.牛奶在玻璃杯里。The bread is very small. 那面包很小。The water is very cold. 那些水很凉。1、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_ teach_catch_wash_do_ like_ say_ learn _eat_read_sing_ buy_study_ come_plant(种植)_2、用括号内动词的适当形式填空。1.
