动词的第三人称单数形式
一、动词的第三人称单数形式规律如下:
1、多数在动词后加s
play—plays like—likesread-reading-sings dance-dancescook-cookslook-looks2、以s,x,sh,ch,o结尾的动词加es
go—goes wash—washeswatch-watchescatch-catchesdo-does3、以辅音字母加y结尾,把y改i再加es
fly—flies study—studiestry-tries
特别注意:以y 结尾的动词变化,看清楚y前面的那个字母是元音还是辅音? 辅音+y的,要改y,例如carry元音+y 的,不改y,例如 play4、5、动词have 的第三人称单数形式是has,这是一个不规则的变化,我们经常会遇到。含有动词第三人称单数的句子,在变否定句时要在动词前加doesn’t;变疑问句时要在主语前加助
动词does。这时句子的谓语动词改为原形。如:
Alice usually plays in the park.Alice doesn’t usually plays in the park.Does Alice usually plays in the park?
Where does Alice usually play?
