Question

motivation可不可数
这是我在朗文当代高级英语词典中查出来的：
1 不可数名词 eagerness and willingness to do something without needing to be told or forced to do it
Jack is an intelligent pupil,but he lacks motivation.
2 可数名词 the reason why you want to do something
motivation for (doing) something
What was your motivation for becoming a teacher?
XXX是更好的动机用英语怎么说?（用比较级和motivation）

Answer 1

作为不可数名词的时候是表示“抽象”的动力、动机,更强调“动力”,朗文字典里也说了,你看例句里也是这么个意思
作为可数名词是“具体形象”的动机,表示1、2、3..个动机,可以通过例举来说明
XXX is a better motivation for doing something
