关于look forward to doing sth和get along with sb的理解

题目

关于look forward to doing sth和get along with sb的理解
look做不及物动词,forward为副词作状语修饰look,然后to作介词连上doing一起做状语也修饰look,等于就是两个状语修饰look,这样理解对么?还是应该理解成他们就是固定搭配,我感觉固定搭配的理解并不是它的最根本的原理啊
还有get不及物 ,along 和 with sb也是一起作状语修饰get的,这个对么?

答案

这本来就是固定搭配,to doing很特殊 还有类似的比如contribute to doing look forward to doing sth to doing连在一起不是做状语,做状语一般都是to do结构 To build the house,the man worked hard. get along with ...
