aabb的例子：
She acts nice and sweet while shes on the stage,
When she gets a break shes on a rampage.
She's very kind in front of the camera,
But in real life she's full of drama.
下面这首儿歌是aabbaa：
Twinkle, twinkle little STAR,
How I wonder what you ARE.
Up above the world so HIGH,
Like a diamond in the SKY.
Twinkle, twinkle little STAR,
How I wonder what you ARE.
ababcc叫Venus and Adonis格式，源于莎士比亚的诗《Venus and Adonis》。开头六句为：
Even as the sun with purple-colour'd face
Had ta'en his last leave of the weeping morn,
Rose-cheek'd Adonis hied him to the chase;
Hunting he loved, but love he laugh'd to scorn;
Sick-thoughted Venus makes amain unto him,
And like a bold-faced suitor 'gins to woo him.
