О каком времени года идет речь?
Березы стояли совсем голые, только кое-где на ветках еще виднелись редкие свернувшиеся листочки. В лесу стояла мертвая тишина, изредка нарушаемая звонким криком синицы.

At night you can go to bed. And the gold piece will grow.
In the morning you get up and come back; and what will
you find? You'll find a beautiful tree with many gold
pieces on it.”
“Oh! How nice!" cried Pinocchio. He forgot his Papa,
the new coat, and the schoolbook. He said to the Fox and
the Cat, “I'll go with you."
ACTIVITIES
"I want to go to school.”
"Look at me!” said the Fox. “I lost my leg because
I learned at school."
“Look at me!” said the Cat. “I lost my eyes because
I learned at school."
Suddenly a little bird began to sing. It said: “Pinoc-
chio, don't listen to them they are bad friends!” Poor
little bird! The Cat jumped at it and ate it up. Then he
shut his eyes again.
“Poor bird!” said Pinocchio to the Cat. “Why did you
eat it up?"
"Because it listened to our talk."
Suddenly the Fox said to Pinocchio:
"Do you want to have a lot of money?”
"Oh, yes, but how?”
“Don't go home. Come with us and we'll show you
how."
“Where shall we go?”
“You'll see," answered the Fox.
Pinocchio thought a little and then he said:
“No, I won't go with you. I'll go home to my Papa.
Te wants to see me."
"Well, then," said the Fox, "go home with your five
gold pieces. But if you want to have two hundred gold
pieces, come with us."
"But how can I get them?”
“I'll tell you,” said the Fox. “We'll go to a field. In
the field you must make a little hole and put into it one
gold piece. Then you must throw some earth into the hole
and make a little hill. After that throw water on the hill.
