A. 雅鹿羽绒服中的背景音乐是一首英文歌是谁唱的
Roll Up Your Sleeves - Meg Mac
Roll up your sleeves
And face the faces looking right back at me
It's easier to leave it all
It's easier to fake it oh oh
So I go and I took the free
'Cause people there they're just like me oh
Ooh well everything is gonna be alright
Everything is gonna be alright
Oh they're hunting me
And he is not fancy he just wares black
Head to toe
And oh, they're hunting me
So I go and I change my name
But they're chasing them just like me
Ooh well everything is gonna be alright
Ooh well everything is gonna be alright oh
Roll up your sleeves
And roll up your sleeves
Everything is gonna be alright
Oh everything is gonna be alright
Everything is gonna be alright
B. red apple 前面的冠词用a 还是an 为什么
a用在以辅音（指辅音音素）开头的词前， an用在以元音（指元素音素）开头的词前
所以用a red apple
则an apple
