скажите пожалуйста как читается стих Робин Бобин (Чуковский)
По-английски,русскими буквами,пожааааааааалуйста очень надо:
Robin the Bobbin the big-bellied Ben,He ate more meat than fourscore men;
He ate a cow, he ate a calf,
He ate a butcher and a half,
He ate a church, he ate a steeple,
He ate a priest and all the people!
A cow and a calf,
An ox and a half,
A church and a steeple,
And all good people,
And yet he complained
that his stomach wasn't full.
