I"m going to后面能不能加go to?

Im going to后面能不能加go to? I'm going away for a long time.为什么这里going后面不用加to呢? I'm going to go,too. going to是一个固定词组吗?后面为什么还要用go to 比如 I'm going to go to a concert tomorrow. i'm going to go home and read the new books中间为什么要加and go后面可以加持续性的短语或动词吗go是短暂性动词,可以加延续性的短语的吗 英语书上的是I`m going to Tibet for a week I'm going my way还是I'm going to my wayI'm going my way出自动画片《NANA》的一首曲子.这里怎么不加to啊.be going to是固定搭配吧,从语法上分析go是个不及物动词,接不了宾语.后面要接东西可以用不定式作 如：I'm going to...但是后面加go to the library,是I'm going to the library还是I'm going to 好像是英语书上写错了,但又好像是老实讲错了,我也不确定 A.I am going to beijing. B.I am going to go to beijing.我将要去北京 be going to加地点时是不是要省略后面的go to i'm going to go to park 和 i'm going to park 啥区别? I'm going home和I'm going to school为什么going home 不加to? I’m going to go to Hainan 一般疑问句 i m going to go to America什么意思 I'm going to go brush my teeth 还是 I'm going to brush my teeth I'm going to go to the park.还是I'm going to the park.一般将来时be going to 我想问个英文问题,‘我打算购物“,用I am going to shopping,还是I am going to go shopping想问一下to 后面能不能直接shopping,如果不能,请告之为什么不能,谢谢! 关于be going to的用法be going to后面不是只能接动词原形吗 ,可是I’m going to a concert（八年级课文）后面怎么接名词?是省略了go It's going to be后面能不能加wind?为什么?打错了 是It's going to后面能不能加？为什么？= =
