关于to的问题

Question

he invited me to her party
he invited me to play games 按道理是V+sb+to do才对 为什么上面的也要to
这里的to做的成分一样吗。

Answer 1

前者中的to充当介词，invite sb. to sp. 邀请某人去（某处）
后者中的to为不定式标志，to do sth. 充当目的状语。invite sb. to do sth. 邀请某人做某事追问

哦, 还有 how are you 这里的be为什么不用助动词.

追答

助动词是指do/ does/ did/ have / has / had，出现动词或完成时才会用。
如：I went to Beijing yesterday. Did you go to Beijing yesterday?
She has been to Beijing. Has she been to Beijing?
而how are you中的回答是I am fine。句中有be的问句，直接将be提前。

Answer 2

第一个是短语:invited to,后面加名词:第二个to是放在动词前的
