переведите текст : My Naughty Little Sister Goes to the Theatre Once when my little sister was four, our moth¬er took us to the theatre. The theatre was very beautiful. My sister and I liked it very much. When we were in the theatre, my little sister did not talk. She looked at the curtain and at the beautiful walls and the big lamps over our heads. She looked at the boys and girls and at their moth¬ers and fathers. But when the curtain went up and a little funny man came out, she looked only at this funny man. His name was Humpty-Dumpty. He said: "How do you do, little boys and girls?" "How do you do?" we all said. But my little sister cried: "Hullo, Humpty-Dumpty!" Everybody laughed, and Humpty-Dumpty said: "Hullo, little girl!" Then beautiful dolls came out and danced. They had very beautiful dresses on, all white and blue. Humpty-Dumpty began to dance, too, but he fell on the floor. And then Humpty-Dumpty said: "Who wants to dance with me?" You know that my little sister was very naugh¬ty, don't you? Do you know what she did? She ran to Humpty-Dumpty and said: "I want to dance with you." Everybody laughed. Humpty-Dumpty laughed, too. The other children ran to him, too, and they all began to dance. "Now, children," he said, "go to your seats." All the children went to their seats, but my little sister did not go to her seat. Do you know why she did not go to her seat? She ran away. Yes, she ran away. She wanted to see the dolls behind the curtain. She found the dolls. The beautiful dolls talked to my sister, and they gave her an ice. Humpty-Dumpty found my little sister and took her to our mother. Everybody laughed, but my mother was very angry. Do you know what my naughty little sister did then? She jumped up on her seat and cried: "I saw them. I saw the dolls. They are not dolls. They eat ices. They are little girls!" My little sister was a very naughty girl, wasn't she?
