about the fish.
"You fool!" she shouted. "We need a new bucket
Go back and ask for a bucket!”
So the fisherman went back to the sea. It was calm.
He called the golden fish and it swam up to him.
"What do you want, good man?" it asked.
"My wife wants a new bucket," said the fisherman.
"You can have your wish. Go home now," said the
fish and swam away.
The fisherman went home and saw a new bucket,
but his wife was still angry. She wanted a new
house. So the fisherman went back to the sea and
called the golden fish again. This time the sea was
not so calm.
The fish granted his wish and the fisherman went
back home. He saw a beautiful new house, but his
wife was still angry. She wanted to be rich with a
huge house. So the fisherman went back to find the
fish. The sea was dark now and the sky was grey.
The fish granted her wish, but still she wasn't
happy. She wanted to be a queen with a palace and
servants so she sent her husband back to find the
fish. The fish granted her wish, but still she wasn't
happy. She wanted to be the Queen of the Land
and Sea, with the golden fish as her servant.
The fisherman went back to the sea and called the
golden fish. The sea was stormy and there were
clouds in the sky.
"I'm sorry, dear fish!" he cried. "Now my wife wants
to be Queen of the Land and Sea, and she wants
you to be her servant."
The fish didn't answer. It turned and swam away.
The fisherman went home. He couldn't see the
palace or the servants. All he could see was his
small house and his wife. She was poor again and
in front of her was the old bucket. перевести И НЕ ПИШИТЕ АЛАЛВДВБЬВБВЬА ПЖ ДАЮ МАКС БАЛ
