或者是木管乐器，换句话说，这里演奏的是什么乐器，还有柴可夫斯基在这首协奏曲的开始部分，运用了动机还是主题？

In other words, what — or the woodwinds — what family of instruments is playing here and is Tchaikovsky using a motive or is he using a theme at the very beginning of this concerto?

除了没有统一的主题之外，两本书还共同隐含了一条信息，作者说，那就是“人是根据动机作出反应的”。

Despite the lack of a unifying theme, there's an underlying message to both books, according to Levitt and Dubner, which is that "people respond to incentives".

youdao

让我们看看到底发生了什么，正是动机，一，二，三，四，一遍又一遍，然后是主题？

Let's see what happens here, just the motif, one, two, three, four, three four, one two, and then the theme.

youdao

Do we have a theme or do we have a motive and which do this--are the violins playing?

主题还是动机,那些小提琴在演奏什么
