English Poem to help with your Pronunciation

Dearest creature in creation
Studying English pronunciation,
I will keep you, Susy, busy,
Make your head with heat grow dizzy.
Tear in eye your dress you'll tear,
So shall I! Oh, hear my prayer,
Pray, console your loving poet,
Make my coat look new, dear, sew it!
Just compare heart, beard and heard,
Dies and diet, lord and word,
Sword and sward, retain and Britain.
(Mind the latter, how it's written).
Made has not the sound of bade,
Say said,
