没有意义,它是一个助动词,帮助疑问的,用助动词后面的动词要用原形
补充：不一样,一个是谓语动词do的第三人称单数形式,“做”
第二个就是助动词了
Does he do his homework in the evening?
Does she have e ping-pong ball?句中的 does
Does she have e ping-pong ball?句中的 does
有实在意义吗?它起什么作用?当加了does之后,谓语动词要用什么形式?
再问下...
He does his homework in the evening
Does she have e ping-pong ball?
这两个句子中的 Does 用法一样吗？如果不通，他做什么句子成分，
请把He does his homework in the evening 变成一般疑问句
