记忆方法
ory是名词后缀。
我们都知道：人类的活动就是两个：一是理论、二是实践。
实践是自己亲自做=do；而理论，就是你需要去学的，去自己看和观察=see。
所以，供我们看的东西，就是理论，学说，见解、看法。

小知识
When you have a theory, you have a set of beliefs or principles that might not be proven yet. Does anyone have a good theory for where missing socks go when you do laundry?
A theory is a set of accepted beliefs or organized principles that explain and guide analysis and one of the ways that theory is defined is that it is different from practice, when certain principles are tested. For example, you could be a musician who plays well but who doesn't have a lot of experience with the theory of music. This word is a noun and comes from the Greek theoria, which means “contemplation or speculation.”
