rather than do or doing sth?看看这句话

题目

rather than do or doing sth?看看这句话
I believe parents should firstly encourage in young children a love of learning,based on curiosity and a respect for the intellect,rather than forcing them to study.
我觉得是rather than force them to study,我们以前学的都是prefer to do rather than do sth为什么这里不是呢?

答案

固定搭配是rather和prefer连用的,用原形
只有rather than的话用ing形式
