一般现在时、动词第三人称单数变化规则一、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， etcHe 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：①陈述句：She is a student.一般疑问句→ Is she a student？否定句→ She is not a student.②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don’t(I，you,以及复数）， doesn’t（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:①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 don't get up at 7：00 every morning.②陈述句：She has a little brother.一般疑问句→ Does she have a little brother？ 否定句→ She doesn’t 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。
