Перекласти з англійської уривок з Чарівника країни Оз.(можно на русский).

 

Adventures, they found the Wizard of OZ. He told them that the scarecrow was clever enough to think of looking for the wizard and he already had a brain. The tin man could feel so sad because he has  a heart to feel with. The Wizard told the lion that his protection of his friends made him a brave lion. The scarecrow, the lion and the tin man were very happy.

"Bow wow!", barked Toto, Dorothy's dog. "Yes, that's right", said the scarecrow. "What about Dorothy and her dog? Can't you help them go home to Kansas?".

"Well, I can try", said the Wizard. "Dorothy, close your eyes. Now say to yourself three times,

"There's no place like home.

There's no place like home.

There's no place like home."

Dorothy closed her eyes and held her dog tight. She said, "There's no place like home", three times. She was taken again by a great wind and when she opened her eyes, she and Toto were in her own bed at home. She was very happy!
