关于v.的单三形式：
○1通常在动词后加s。 如 work→works
○2以s, x, ch, sh结尾的动词加es。 如 teach→teaches
○3以辅音字母加y结尾的动词，变y为i，再加es。如 study→studies

drinks goes stays makes looks has passes carries comes watches plants flies studies brushes does teaches

drinks goes stays makes looks has passes carries comes watches plants flies studies brushes does teaches.动词三单变化规则如下：
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
最后记住元音字母+Y结尾都直接加S的,如say-says
