перекладіть будь ласка частину другу Good Morning,Miss Dove!!
Randy looked around and began to read. Tom told his younger brother, what he had seen from the plane in which he was brought back to England. He wrote that the land below looked like the map, they had used at the Geography lessons at school. Then he wrote how he had suffered on the raft with almost no water to drink. "Do you know who I was thinking about then? It wasn't a boy or a girl," he explained. "I was thinking about Miss Dove, and out there in the open ocean I played a game. No, I am not joking. And it helped me to stay alive1.1 imagined that I was back again in the Geography class; I remembered the look Miss Dove gave us when we wanted to leave the classroom for a drink of water. So I imagined that I was at her lesson and kept thinking2 all the time, 'The bell will go in a few minutes. You can wait a little longer. You must wait for the bell.'And it made everything easier. It was almost as difficult there in the ocean as it had been at school. Tell that to the boys, will you?"Randy stopped suddenly."Is that all?" Miss Dove asked."No," said Randy. His face became very red. "It says here, "Please thank Miss Dove and give her a kiss for me3."Miss Dove went up to the boy."Well, Randy," she said. "I'm waiting."In the silence that followed little Randy kissed "the terrible Miss Dove". Nobody in the class laughed or even joked about it; everybody was silent except one girl who suddenly spoke."It's like a medal," she said. "It's just like a medal he has given to Miss Dove."
