do或does怎么插入一般疑问句如：I have a volleyball。改成一般疑问句并作肯定回答
如果谓语是行为动词,就要用到助动词do 来帮助这个动词表达否定或疑问.如： I have a volleyball. 这里have 是动词,所以变成疑问句时它不能动.要借do 来表示疑问句.并且把do 放在主语I 的前面：
Do I have a volleyball?
如果主语是she ,he ,it, 而且动词后加了s. 就用does.而原先的动词用原形 如：
He likes playing football.
Does he like playing football.

do you have a volleyball.
yes,I do.
第三人称用does she/he/it
主格用do I/we/they/you

一般疑问句：do you have a volleyball?
肯定回答：yes,l do.

do是助动词，可以加，
如：does he is a football player.
ok?
