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—gets
ii)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—catches
iii)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—worries
③④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?

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]
二、对比词形变化中原词词尾变化之异同: 变“y”为“”现象 双写最后辅音字母现象
例词:
①baby-babies
②carry-carries
③study-studying
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]
