Question

He spent more time doing exercise. 为什么不能是He spent more time to do exercise.
he spends more time doing exercise.为什么不能是he spends more time to do exercise

Answer 1

首先，必须用过去式，因为锻炼活动已经过去了；其次，spend……doing是固定搭配。

Answer 2

就是习惯问题。

人文背景影响，演变出来的。没法去讲道理。

Answer 3

spend some time to do sth/
spend some time doing sth,
第三人称单数，spends,过去式spent

Answer 4

spend doing是固定用法，没有spend to do这个搭配。

Answer 5

是这样的：
spend time doing sth. 是指花时间做某事
spend time to do sth. (to do sth.)是接目的，
比如这句话里面
He spend more time doing exercise to lose weight就对了
