more than 的成分

问题描述:

more than 的成分
The total sales of the company didn't amount to more than a few million dollars,我想问一下,more than 加在to的后面,more than的成分是什么,可以看成介词吗,应该不行吧

more than
adj.
(comparative of `much' used with mass nouns) a quantifier meaning greater in size or amount or extent or degree
adv.
comparing quantity or quality
这里应该看成副词.to后面+的是名词性短语,不能加介词了.
