2、 动词的三单形式
观察下列句子的动词
He plays basketball every afternoon.
They play basketball every afternoon.
Tom usually listens to music when he is nervous.
Tom and Helen usually listen to music when they are nervous.
Ms White always runs for 1 hour before breakfast.
We always run for 1 hour before breakfast.
总结:在一般现在时中,跟在第三人称单数后面的动词也要变成相应的三单形式,
动词三单的变化规则
1、 一般情况下直接加s,如speak-speaks, like-likes,play-plays
2、以s, x, sh,ch,o 结尾的加es,如 wash-washes, go-goes,do-does, watch-watches
3、以辅音字母+y 结尾的,改y 为i 再加es,如 study-studies,try-tries
4、特殊变化,如 have-has
句型变化
一般现在时的肯定句变疑问句,三单用Does ,其他用do;
注意,Do Does 后动词用原型
例如:He plays basketball every afternoon.
--- Does he play basketball every afternoon?
肯定回答:Yes,he does.
否定回答:No,he doesn't.
They play basketball every afternoon.
---Do they play basketball every afternoon.
肯定回答:Yes,they do.
否定回答:No,they doesn't.
一般现在时的肯定句变否定句,在动词前面加Doesn't 或者 don't;
