《stomp the enemy》的歌詞如下：
I got my hands up in the air
No weapons but I'm here to clear my air
Everybody with me say yeah
Cause I stomp the enemy
Chorus:
I stomp the enemy
I stomp the enemy
I stomp the enemy out of my way
I stomp the enemy
I stomp the enemy
I'm coming for you, you better run away
Verse 2:
I'm coming for you with a vengeance
You better run, you better listen
And let my music take control of your senses
So you can hear me, see me, and believe me
Chorus:
I stomp the enemy
I stomp the enemy
I stomp the enemy out of my way
I stomp the enemy
I stomp the enemy
I'm coming for you, you better run away
Bridge:
Oh oh oh, oh oh oh oh oh oh oh oh oh oh oh
Oh oh oh, you can run but you can't hide
Oh oh oh, I got my army of millions behind me
So just stay ready for war
Chorus:
I stomp the enemy
I stomp the enemy out of my way
Come and test me, we don't need no plea deals in this situation, let's just have some blood shed函式$f(x) = x^{3} + ax^{2} - x - 5$在$( - 2, - 1)$上不單調，則實數$a$的取值範圍是（）。
A. $( - \infty, - 2)$
B. $( - \infty, - 3)$
C. $( - 2, + \infty)$
D. $( - 3, + \infty)$
解：函式$f(x) = x^{3} + ax^{2} - x - 5$在$( - 2, - 1)$上不單調，即函式$f(x)$在$( - 2, - 1)$上單調遞增或單調遞減，則$f^{\prime}(x) = 3x^{2} + 2ax - 1 = 0$在$( - 2, - 1)$上有兩個不同的實根，即$\Delta = 4a^{2} + 12 > 0$且$- \frac{3}{a} \in ( - 2, - 1)$，解得$a > - 3$，故選D。
