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：假设主语不是第三人称单数形式，就直接用动词原形；假设主语是三单，后有will等情态动词修饰时，动词也用原形。〕

二、动词三单变化规那么〔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那么及发音规律，同名词单数变复数大致一样，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，原词的元音局部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构造。 1、肯定/否认句

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，一般疑问句构造为“Is+三单+表语？〞。它的肯定答复为： Yes, 三单+is. ;否认答复为：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？〞。它的肯定答复为：Yes，三单+does.;否认答复为：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。
