B: Is that M as in Mary, E as in elephant, and G as in girl?
那是Mary的m、elephant的e，girl的g嗎？
 
as in可以用來進(jìn)一步解釋情況，猶如中文里的“像……那種”：
 
A: I just ate a Chinese buffet for only 2.99 dollars.
我剛只花了2.99美元吃了份中式自助餐。

B: As in the all-you-can-eat kind? That's so cheap!
是吃到飽的那種嗎？還真便宜！
 
你也可以用as in來提問，以確定自己沒有誤會對方的意思:
 
A: I made a million last year.
我去年賺了一百萬。

B: Is that as in dollars?
你說的一百萬是美元嗎？
