第三人称单数是英语中的一种语法,也称“三单”或“单三”,用于一般现在时的句子,当动词在第三人称单数后时【she、he、it、不可数名词和人名（一个人的）】

大家都知道,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：

第四篇：第三人称单数练习

时态一：一般现在时 第三人称单数 及动词变化规律及一般疑问句

一：什么是三单？三单的题型：一般用在选择题与填空题（用适当的形式填空）

一：除了我（I）和你(you)我们（we）你们(you)他们(they)之外都是三单 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。

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，如何由原形变为第三人称单数？规律是什么？ 1：一般情况下加S: learn----learns

2: 以“s, x, ch, sh,o”结尾的，在词尾加“es”，teach－teaches Wash----washes go－goes

do－does

3: 以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”

fly－flies ；carry－carries study－studies;worry－worries 4:以元音字母加Y,直接加S :say-says 5：记住最为特别的be的三单is，have的三单是has。Do--does

三：陈述句变一般疑问句变化规则

1：句中有“is、are或can”的句子，把“is、are或can”提到句首，若句子为过去时，则将相应的变为过去时（was,were could），句号变问号。

例如：

原句

一般疑问句

He is Tom.Is he Tom? This is a bird.2：以“I am......”和“We are......” 开头的句子，把“I am......”和“We are......均变成”Are you......？“

句号变问号，其他单词不变。

3.句中没有”am、is、are和 can“的句子.如果主语是第一人称、第二人称或第三人称复数的句子，句首加”Do“,”I、We“变成”you“，句号变问号，其余单词不变。

4.句中没有”am、is、are“ 的句子，如果主语是第三人称单数时，句首加”Does“,动词变原型，句号变问号，其他单词不变。

5：句中单词变化总结：i-you am-are some-any 如用了Does,句中谓语动词要改为原形。

注：变后疑问句的第一个单词的第一个字母必须大写!

第五篇：动词第三人称单数

动词第三人称单数

一、动词第三人称单数的变化规则及发音规律

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]

名词变复数规则

1．一般名词复数是在名词后面加上“s”，如map→maps，bag→bags等；

2．以s，sh，ch，x等结尾的词加“es”，如bus→buses，watch→watches等；

3．以辅音字母＋y结尾的词，变y为i加es，如baby→babies等；以元音字母＋ y结尾的名词变复数时，直接加s变复数，如monkey→monkeys，holiday→holidays，storey→storeys（楼层）；

4．以o 结尾的名词变复数时：

a）加s的名词有：photo→photos，piano→pianos，radio→radios，zoo→zoos

b）加es的名词有：

potato→potatoes tomato→tomatoes

5．以f或fe结尾的名词变复数时：

a）加s的名词有：

belief→beliefs roof→roofs

safe→safes gulf→gulfs

b）去掉f，fe 加ves的名词有：

half→halves knife→knives

leaf→leaves wolf→wolves

wife→wives life→lives thief→thieves
