名词的复数变化规律一般现在时主语单三人称时的动词变化①在一般现在时中,当主语为第三人称单数时,动词要用“s”型(即第三人称单数形式)。
②所谓动词“s”型的构成,可按名词变复数的规则来记,即:i)在动词尾直接加s。
如:play—plays,want—wants,work—works,know—knows,help—helps,get—getsii)以字母s、x、ch或o结尾的动词加-es;如:guess—guesses,fix—fixes,teach—teaches,brush—brushes,go—goes,do—does,watch —watches,catch—catchesiii)以辅音字母+y结尾的动词,先变y为i,再加-es。
如:study—studies,carry—carries,fly—flies,worry—worries③④强调如何将主语是第三人称单数的肯定句变为否定和疑问句。
现举例说明(用划线部分来说明顺口溜):1)His mother works in a factory.His mother doesn’t work in a factory.Does his mother work in a factory?2)Mr Li teaches us English.Mr Li doesn’t teach us English.Does Mr Li teach you English?3)My brother studies maths well.My brother doesn't study maths well.Does your brother study maths well?。

动词第三人称单数的变化规则在一般现在时的句子中,当主语是第三人称单数时,动词要发生变化。
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,其规律大体有三点:1、一般情况下,直接在动词词尾+s。
2、以s, sh, ch, x, o结尾的动词,在词尾+es。
3、以辅音字母+y结尾的动词,变y为i,再+es。
4、动词have,遇到主语是第三人称单数时,要用has;动词be的第三人称单数形式是is。
5、含有动词第三人称单数形式的句子变否定句时,要用doesn't+动词原形.6、对含有动词第三人称单数形式的句子提问时,要用助动词does。
•动词第三人称单数的用法: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。
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:①HanMei looks like her mother. 韩梅看起来像她的母亲。
②Beijing is in China. 北京在中国。
③UncleWang 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。

动词三单式变化规则
嘿,朋友们!咱今天来聊聊动词三单式变化规则呀!你知道一般现在时里,当主语是第三人称单数时,动词得有啥变化不?比如说,He likes music. 这里的 like 就加了 s 呢!哎呀,这就好像一个小魔术一样,动词就得乖乖变个样!
一般来说呀,大部分动词直接在后面加 s 就行啦!就像 Mary goes to school every day. 这里的 go 就变成了 goes 啦!
还有哦,如果动词是以 s、x、ch、sh 结尾的,那就要加 es 哦!举个例子呗,She watches TV in the evening. 你看,watch 就加上 es 啦!是不是很有意思呀?
要是动词是以辅音字母加 y 结尾的,那得把 y 变成 i 再加 es 呢!比如He studies hard. 这里的 study 就这么变啦!
咱可别小瞧了这动词三单式变化规则呀,这在英语里可重要啦!掌握了它,咱说英语才能更溜呀!大家可得好好记住哟!。

三单使用条件三单使用条件是指英语中第三人称单数形式的动词使用的规则。
在英语中,动词的形式会根据主语的人称和数的不同而发生变化。
而在第三人称单数形式中,动词的变化规则有一些特殊之处。
本文将详细介绍三单使用条件的相关内容,帮助读者更好地理解和运用这一语法规则。
一、什么是三单使用条件在英语中,动词的三单使用条件表示的是当主语为第三人称单数时,动词需要进行相应的变化。
具体来说,三单使用条件包括以下几个方面:1. 在一般现在时中,动词的第三人称单数形式需要在动词原形的基础上加上-s或-es。
例如,动词work的第三人称单数形式为works。
2. 在一般过去时中,动词的第三人称单数形式与动词原形相同。
例如,动词run的第三人称单数形式仍然是run。
3. 在一般将来时中,动词的第三人称单数形式需要在动词原形的基础上加上will。
例如,动词play的第三人称单数形式为will play。
二、三单使用条件的例子为了更好地理解三单使用条件,下面将通过一些具体的例子来说明:1. 一般现在时:He plays basketball every day.(他每天都打篮球。
)2. 一般过去时:She went to the park yesterday.(她昨天去了公园。
)3. 一般将来时:The train will arrive at 9 o'clock.(火车将在9点到达。
)三、需要注意的细节在使用三单使用条件时,还需注意以下几点细节:1. 当主语为以-s、-sh、-ch、-x、-o结尾的名词时,动词的第三人称单数形式需要在动词原形的基础上加上-es。
例如,watch的第三人称单数形式为watches。
2. 当主语为以辅音字母+y结尾的名词时,动词的第三人称单数形式需要将y改为i,并加上-es。
例如,study的第三人称单数形式为studies。
3. 当主语为不可数名词时,动词的第三人称单数形式仍然和动词原形相同。

一般现在时的句子结构
1、当句子表状态说明主语是什么或怎么样时
句子结构为:主+BE动词(am, is, are)+其他.
否定式为:主+BE动词+not+其他.
疑问句为:BE+主+其他?
例: The twin sisters are from America.
The twin sisters are not from America.

2、当谓语由实义动词充当,主语不是第三人称单数时,
句子结构为:主语+动词原形+其它.
否定式为:主语+don't+动词原形+其它.
疑问句为:Do+主语+动词原形+其它?
例: We speak Chinese.

3、当主语是第三人称单数时:
句子结构为 主语+动词(词尾加s或es)+其它.
否定式为:主语+doesn't+动词原形+其它.
疑问句式:Does+主语+动词原形+其它。
动词三单变化方法
