动词第三人称单数的变化规则及练习
动词第三人称单数变化规则及练习
一、使用情况:
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。
(标志词usuallyoftenalwayssometimesneverevery等)
二、变化规则
1、直接在动词后+s
例如:
like-likesplay-plays
2、以s,x,sh,ch,接尾动词:
+es
例如:
wash-washes
3、以辅音+o接尾动词:
+es
例如:
go-goes
4、以辅音字母+y接尾动词:
变y为i+es
例如:
fly-flies
以元音字母+y接尾动词后+s
例如:
play-plays
5、除上述规律外,还应注意下面三点:
1)动词have,遇到主语是第三人称单数时,要用has;动词be第三人称单数形式是is。
2)含有动词第三人称单数形式句子变否定句时,要用doesn't+动词原形,如:
Hegoestoschoolatsixinthemorning.(变否定句)→Hedoesn'tgotoschoolatsixinthemorning.
3)对含有动词第三人称单数形式句子提问时,要用助动词does
如:
Shegoeshomeatfiveeveryday.(对划线部分提问)→When/Whattimedoesshego
注意:
不规则变化:
have-----has,be-------is,do-----does
