很多同学觉得brave和courageous都表示"勇敢的"，傻傻分不清楚。其实它们之间还是有细微差别的。Brave更强调的是面对危险或困难时，无所畏惧，并且敢于行动的精神。而Courageous则更强调的是面对恐惧或危险时，内心依然平静和坚定，需要更大的勇气。

简单来说，brave更侧重于行动上的勇敢，而courageous更侧重于精神上的勇敢。

让我们来看一些例句：

• The firefighter bravely rushed into the burning building. (消防员勇敢地冲进燃烧的建筑物里。) Here, "bravely" highlights the firefighter's action of rushing into danger.

• It was courageous of her to speak up against injustice. (她挺身而出反对不公正，这需要很大的勇气。) Here, "courageous" emphasizes her mental strength in the face of potential consequences.

• The brave soldier fought in the war. (勇敢的士兵参加了战争。) This sentence emphasizes the soldier's daring actions.

• He showed courageous spirit when facing difficulties. (在面对困难时，他展现了勇敢的精神。) This sentence highlights his inner strength and resilience.

当然，很多情况下，brave和courageous可以互换使用，意思差别不大。但是，理解它们细微的差别，可以帮助你更精准地表达意思。
