什么时候用动词原形
1、与助动词或情态动词do、does、did、shall、will、should、would、may、might、have to、must、need、ought to等一起构成谓语的动词时，要用原形。

used to+动词原形（过去经常…），这结构用于表示过去经常而现在不再有的习惯。比如：
He used to be a science teacher in a private school.
他曾是一所私立学校的自然常识教训。
3、to + 动词原形（不定式表示目的）
在一些句子或者短语后，想要表达做某事的目的，可以直接加上to do形式。也就是说，在任何一个句子后都可以写上to do（to+动词原形）表达作者的目的，期望。
He worked day and night to get the money.
他夜以继日地工作来赚钱。
4、be going to 的含义及结构
含义：表示按计划或安排要发生的动作，也可以表示推测将要或肯定会发生的动作，有“准备;打算”的意思。
结构：be going to 后面需要接动词原形。
注：句子中时常有表示将来的时间状语。
