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 play—plays like—likes read-reads sing-sings dance-dances cook- cooks look- looks 2、 以s，x，sh，ch，o结尾的动词加es go—goes wash—washes watch-watches catch-catches do- does 3、 以辅音字母加y结尾，把y改i再加es fly—flies study—studies 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+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. 1 / 31 / 3 Does Alice usually plays in the park? Where does Alice usually play? 写出下列动词的正确形式：（经常做的规律） 1、I go (go) to school at seven in the morning. 2.
