英语对划线部分提问什么时候用is 或do dose

看句中的谓语动词， 有is，就用is提问。谓语动词是原形， 用do。谓语动词是三单，加s，就用does。谓语动词是过去式ed， 就用did
He is 14. He isn't 14.
He is playing basketball. He isn't playing basketball.
He plays bastetball well. He doesn't play basketball well.
They go to school on foot. They don't go to school on foot.
I washed　my　clothes　yesterday．　　Ididn't wash my clothes yesterday.
注意：用了does和did之后，原来的动词用原形

当对The party is there,I come to the party等一般陈述句的主语，宾语，定语状语表语进行划线提问时就会用到is do does did，这里须强调的是「一般陈述句」，而不是在过去的或者将来时的陈述句。

题目主语是第三人称单数的时候提问把is提前， eg. is it a ball?
一般疑问句 用于第二人称 用do e.g. do you want to sleep?
一般疑问句 用于第三人称单数 用does e.g. does he like you ?
