动词第三人称单数形式

主语有三单, 动词也有三单, 快点来习惯, 体会在心里, 一定要过关. 一、概念

动词第三人称单数：主语是第三人称单数，即谓语动词的发出者是it、she、he、可数名词单数、不可数名词等表示单数概念的词时，实义动词后面要加-s 或-es。（注意：若主语不是第三人称单数形式，就直接用动词原形；若主语是三单，后有will 等情态动词修饰时，动词也用原形。）

二、动词三单变化规则（只有一般现在时才有第三人称单数）

动词第三人称单数的变化规则及发音规律，同名词单数变复数大致相同，请认真观察。1、大多数实义动词在词尾加“s”，在清辅音后发音为/ s / ，在浊辅音及元音因素后发音为

/ z / 。如：speak → speaks /s/ ; come → comes /z/ ; play →plays /z/

2、以辅音字母加“y”结尾的动词，要先将“y”变为“i”，然后再加“es”，读/z/。

如：study→studies /z/ ; fly→flies /z/

3、以“s，x，ch，sh”结尾的动词，在词尾加“es”，发音为/ iz / 。

如：teach→teaches /iz/ ; watch→watches /iz/

4、以“o”结尾的动词,在词尾加“es” 。

常出现的两个以“o ”结尾的动词go 和do 后加“es”，读/z/ 。如：go→goes /z/ ;

do→does /z/

5、记住最为特别的be的三单is ；have 的三单是has。［注意］（1）下面两个动词变三单时，原词的元音部分的发音发生了较大的变化，要记忆。

如：do/du:/ → does/d z/ ; say/sei/ → says /sez/

（2）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］

三、动词第三人称单数的句子结构。

1、肯定/否定句

三单+is + 表语. 三单+动词第三人称单数+其他.

三单+is+not+ 表语. 三单+doesn't + 动词原形+ 其他.

2、一般疑问句

1 ）当谓语动词是be 动词时，一般疑问句结构为“ Is+三单+ 表语？”。它的肯定回答为：

Yes, 三单+is. ;否定回答为：No，三单+isn't.。

2 ）当谓语动词是实义动词时，在肯定句句首加助动词does, 即“Does+ 三单+ 动词原形+

其他？”。它的肯定回答为：Yes ，三单+does.; 否定回答为：No，三单+doesn't. 。

3、特殊疑问句

特殊疑问词+ 一般疑问句

四、要点

1 ）一定要看准句子的主语是第三人称而且还是单数；

2 ）经常与频率副词连用：always （一直，总是），usually（通常），often （经常），

sometimes （有时），seldom （很少），hardly （几乎不），never （从不），once a day （一天一次），twice a week（一周两次），three times a month（一个月三次）。

如:I often speak Chinese. 我经常说汉语。
