一般现在时动词三单变化规则
1. 对于大多数动词，第三人称单数加上-s或-es。
例如：play → plays, watch → watches。
2. 对于以s, sh, ch, x, z结尾的动词，第三人称单数在词尾加-es。
例如：pass → passes, brush → brushes。
3. 对于以辅音字母加y结尾的动词，将y变为i，再加上-es。
例如：fly → flies, study → studies。
4. 对于以元音字母加y结尾的动词，直接加上-s。
例如：play → plays, enjoy → enjoys。
5. 对于以辅音字母加o结尾的动词，通常在词尾加-es。
例如：do
→ does, go → goes。
但也有例外，如：go → goes。
6. 仅有少数几个动词在第三人称单数形式不变。
例如：have → has, do → does。
值得一提的是，对于be动词，第三人称单数形式是is。
例如：I am, he is。
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.sometimes goes to school by bike.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;（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’tI,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;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 Lucy's. 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.

My father reads newspaper in the evening.7、把下列句子变为疑问句,并做肯定和否定回答;1. My brother can ride a horse.2. We clean the classroom after school.___________________________________________________________。
一般现在时态一、一般现在时的用法:1.表示经常或者反复发生的动作. 如: 我每天吃午饭. I have lunch every day.2.还表示现在存在的一种状态. 如：我姐姐是一位老师．My sister is a teacher.3.客观真理，客观存在，科学事实。
例如：The earth moves around the sun.地球绕着太阳转。
二、一般现在时态时间状语：经常与often（经常）sometimes（有时）always（总是）usually（通常）等频度副词连用（位于系动词之后，行为动词之前。
），也经常与every day （每天）, every week（每周）, every month（每月）, every term（每学期）, every year （每年）, once a week （一周一次），twice a year（一年两次）等时间状语连用。
三、一般现在时第三人称单数问题一般现在时中，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：1.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。
2.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 c akes.王叔叔经常做蛋糕。
3.单数可数名词或"this / that / the/ a +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。
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。
）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。
