Ex 1
Tiger, tiger, burning bright

In the forest of the night

What immortal hand or eye

Could frame thy fearful symmetry?


Ex 2
Ask not the cause why sullen Spring

So long delays her flowers to bear,

Why warbling storms invert the year

Chloris is gone; and fate provides

To make it Spring where she resides.


Ex 3
I heard a thousand blended notes

While in a grave I sate reclined,

In that sweet mood when pleasant thoughts

Bring sad thoughts to the mind


Ex 4
To me, fair friend, you never can be old,

For as you were when first your eye I eyed,

Such seems your beauty still. Three winters´ cold

Have from the forests shook three summers´pride.
