动词第三人称单数练习
使用情况:
在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加-s或-es。(标志词usually often always sometimes never every等)
二、变化规则
1、直接在动词后+s
例如: like- likes play-plays
2、以s, x, sh, ch, 接尾的动词:+es
例如: wash-washes
3、以辅音+o接尾的动词:+es
例如: go-goes
4、以辅音字母+y接尾的动词:变y为i+es
例如: fly-flies
以元音字母+y接尾的动词后+s
例如:play-plays
5、除上述规律外,还应注意下面三点:
1) 动词 have ,遇到主语是第三人称单数时,要用 has; 动词 be 的第三人称单数形式是is。
2)含有动词第三人称单数形式的句子变否定句时,要用 doesn't + 动词原形,如: He goes to school at six in the morning. (变否定句)→ He doesn't go to school at six in the morning.
3)对含有动词第三人称单数形式的句子提问时,要用助动词 does
如: She goes home at five every day. (对划线部分提问)→ When / What time does she go
注意:不规则变化:have-----has,be-------is,do-----does
