РЕБЯТ,ПОЖАЛУЙСТА,СРОЧНО НУЖНО СДЕЛАТЬ ПЕРЕСКАЗ И ПЕРЕВЕСТИ ПРЯМУЮ РЕЧЬ В КОСВЕННУЮ!!!Read what happened in the hospital when Emily and her friends were visiting Jane. Retell the story. Use reported speech. In the room where Mr Small, Dr Foam and Mrs Bulmer were talking to the children, there were some really old people. Mr Small went up to one of them. "I see that you're a very old man," he said. "Yes, I am. I'm 90," the old man replied. "Could you give the children here some advice about a balanced diet and a healthy lifestyle?" Mr Small asked. "Sure. Follow my example. Don't smoke, don't drink, don't eat too much sugar or fat and drink lots of water." At that moment Dr Foam found another old man, who looked older than the first one. He was sitting in a wheelchair, but his eyes were merry and bright. "How old are you, sir? Dr Foam asked. "I'm ninety-five," the man replied. "Can you tell us why you have lived so long?" Doctor Foam asked. "It's easy. I always do exercise, and I don't smoke or drink. T spend a lot of time in the open air and I'm a vegetarian." Just then Mrs Bulmer decided to join in the conversation. She saw a very, very old man in the corner of the room. He had no teeth or hair and he couldn't see or hear very well, so she had to come very close to him. The children followed her. "May I ask you a couple of questions, sir," she shouted. "Yes," the old man whispered. "Why have you lived so long, sir?" Mrs Bulmer asked. "I don't know," the man replied. "Tell us about your lifestyle," Mrs Bulmer continued. "OK, then. I smoke thirty cigarettes a day and drink a bottle of whisky every day. Sometimes I also have two bottles of beer. I never eat vegetables or fruit and I live on chocolate and cakes." "How old are you, sir?" Mr Bulmer exclaimed. "I'm forty," the "old" man replied.
