Brimming with excitement means extremely full of excitement.
充满兴奋意味着极度兴奋
Let me give you a visual example. The top edge of a cup or glass is called the brim. Usually when we fill a cup with liquid, we leave some space; we don't fill it all the way up to the brim. So if you do fill the cup up to the brim, the cup would be considered extremely full.
让我给你们一个直观的例子。杯子或玻璃杯的上边缘叫做brim。通常当我们把杯子装满液体时，我们会留出一些空间;我们不会一直加到瓶口。所以如果你真的把杯子装到了brim的位置，杯子会被认为是非常满的。
This is why the expression brimming with means extremely full -we usually use it with an emotion or some other non-physical thing. Someone who generates a lot of good ideas could be described as brimming with ideas, or someone who is very naturally skilled would be brimming with talent.
这就是为什么“brimming with”这个短语的意思是“非常满”——我们通常把它和情感或其他非物质的东西连用。一个能产生很多好主意的人可以被描述为brimming with主意，或者一个天生就很有技巧的人会brimming with天赋。
They are in their prime and brimming with happiness. I have never felt so much joy as when I see them together.
他们风华正茂，而且洋溢著幸福。当我看到他们在一起时，我感到从未如此开心。
