Listen to the song by Owl City and fill in the gaps. You will find some examples of the infinitive.

1. You would not believe your eyes
   If ten million fireflies
   lit up the world as I fell asleep
   'Cause they'd fill the open air

   (Please take me away from here)
   When I'm far too tired [ ]
