Пожалуйста, можно перевод 5-й главы Питера Пэна.
Peter and the children flew over the city and over fields and trees. They flew over the sea, and
under the moon many times. Suddenly, Peter pointed and called to the others.

“Look!" he cried. “There it is! There's the Neverland!”

The children knew at once, because it was the same as it was in their dreams. They felt as if
they were coming home.

Peter turned to the others.

“Do you want an adventure?” he asked. “Or do you want tea first?”

“Tea first,” said Wendy quickly. Michael held her hand tightly, nodding his head.

“What kind of adventure?” asked John.

“There is a terrible pirate down there,” said Peter. “Let’s go down and get him!”

“A pirate?” asked John. “A real one?”

“Yes," said Peter. “His name is Hook, and he is the worst of all pirates.”

“Is he big?” asked John.

“Not as big as he was,” said Peter. “I cut his hand off, you see!”

“So, he can't fight?” asked John.

“oh, he can fight!" said Peter. “He has a sharp hook on the end of his arm."

The children looked down at the Neverland and saw that the whole island was full of life. The
Lost Boys were looking for Peter. The pirates were looking for the Lost Boys. The Indians were
looking for the pirates, and the animals were looking for the Indians. They all walked round and
round the island, but they did not meet because they were all walking at the same speed.

The first to stop moving were the boys. They were tired, and they sat down on the ground near
their underground home. Only the Lost Boys knew where the underground house was. The
entrances were seven trees with holes in their trunks. There was one hole for each Lost Boy (Nibs,
Tootles, Slightly, Curly and the Twins), and one for Peter Pan.

“Where is Peter?” asked Nibs.

“I want him to come back and fight the pirates," said Tootles.

“I am not afraid of the pirates," said Slightly, but the other boys knew that this was not true.
Everyone was afraid of Hook and his men.

Just then, there was a sound.

“Quick! The pirates are coming!” cried Nibs.

The boys disappeared into their underground home like rabbits just before the pirates arrived.
