1. appreciate 指对事物有深入的理解力或较高的修养，并能鉴赏、品评等，相当于 understand or enjoy fully。如：

Not many of us can appreciate Beijing opera. 我们中间没有几个人能真正欣赏京剧。

You will appreciate his novels if you read his autobiography. 如果你读了他的自传，你就更能欣赏他的小说了。

2. enjoy 表示“欣赏”，属一般用语，不像 appreciate 那样具有较高的修养，也无需“鉴赏”，只是得到感官或精神上的乐趣或满足，侧重享受，相当于 get pleasure from 的意思。如：

I enjoyed the play very much. 我很欣赏这出戏。

We didn’t enjoy his lecture. 他的讲课，我们并不欣赏。
