英语第三人称单数总结晕练习

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—play s like—like s read-read s sing-sing s dance-dance s cook- cook s look- look s

2、以s，x，sh，ch，o结尾的动词加es

go—go es wash—wash es watch-watch es catch-catch es do- do es

3、以辅音字母加y结尾，把y改i再加es

fly—fl ies study—stud ies try-tr ies

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 carr ies; 元音+y 的，不改y,例如play play s.

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.

Does Alice usually plays in the park?

Where does Alice usually play?

二、写出下列动词的正确形式：（经常做的规律）

1、I (go) to school at seven in the morning.

2. Mike ( do) his homework at eight in the evening.

3. His father often ( read) books in the library on Saturday.
