英语分析:Rather than go straight on to university why not get some work experience first?

我的分析是:
go straight on 是词组,意为“直走”“直接去”,“勇往直前”等意思.例如：
1.Turn left at the next corner and go straight on(下一个拐角左转然后直走）
2.Go straight on untill you come to a shop.(直走,直到一家商店为止）
3.Don't give up just go stright on!(别放弃,要勇往直前!）
在“Rather than go straight on to university why not get some work experience first?”中,您要将"go"和"to" 断开,这并非词组"go to "（去.）,"to"表示方向或处所,修饰的是"go straight on"(直接去.）的方向或处所.
另外：rather than 和why not 后接动词原型,这点要注意,考试常考的啊.
