either or、neither nor、whether or、分别是什么意思.并举一个例句

either or或者……或者……eg:It is your choice!Either she leaves or I will(你看着办吧!要么她走,要么我走!）neither nor 既不……也不……eg:I have never been to Paris nor New York.(我没去过巴黎也没去过纽...eg:I have never been to neither Paris nor New Yorkwhether you like it or not,you are going to have to face him one day.(不管你喜不喜欢，总有一天你必须面对他。） 这一句对么？？为什么可以把“are going to”和“have to”放在一起答案绝对正确。are going to 是将来固定结构have to这里是动词短语“不得不”have to中的have是情态动词而are是be动词，为什么能出现在一个句子中呀be going to do sth.句型结构
