1、1动词的第三人称单数形式动词的第三人称单数形式规律如下:1、 多数在动词后加 s playplays likelikes read-reads sing-sings dance-dances cook- cooks look- looks2、 以 s,x,sh,ch,o 结尾的动词加 es gogoes washwashes watch-watches catch-catches do- does3、 以辅音字母加 y结尾,把 y改 i再加 es flyflies studystudies try-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+
2、y 的,要改 y,例如 carry carries; 元音+y 的,不改 y,例如 play plays.4、 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。5、 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 doesnt;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 doesnt usually plays in the park.2Does Alice usually plays in the park? Where does Alice us
