помогите пожалуйста, 6 класс

as blind as a bat
as black as night
as wise as an owl
as good as gold
as green as grass
as stubborn as a mule
as hard as nails
as busy as a bee
as happy as a lark
as pretty as a picture
as comfortable as an old shoe
as free as a bird
as poor as a church mouse
as warm as toast
as old as the hills
as hard as iron
