Олимпиада по английскому 7 класс. 3agahne 1: Reading Read the text and use the sentences (A-H) to complete the gaps. There are two extra sentences you will not need. Dogs help people get well. Joan Gray is a nurse. Often her patients are people who have now returned home from hospital but are not ready to go back to work. She also spends a lot of her time visiting people still in hospital. They look forward to seeing her, especially because she doesn't go alone. She takes her dog, Bertie, with her. Joanne says that Bertie makes her patients feel better. Bertie started going to work with Joanne four years ago and she is sure that he has made a real difference. "Bertie is brilliant with people", she says. " For example, he helps patients who cannot use their arms very well. He can also help patients who are very nervous or depressed. They tell me they feel calmer and happier when he is with them. Joanne realized several years ago how much her patients enjoyed seeing an animal. "I used to have a cat that I took with me sometimes on my visits. My patients always asked me about him and all said they loved seeing him. It's easier to take a dog to see someone. Research shows that pets can reduce stress and help people get better more quickly from all sorts of illnesses. For instance, one man in hospital didn't want to talk to anyone but he spoke to Bertie. He told him he hated the hospital food and didn't like the people in the beds next to him. So the hospital was then able to get him the food he liked. Not all dogs are suitable for visiting sick people. Some dogs are afraid of people they don't know. But the right dog can help people get better. A. Joanne can give lots of examples of this. B. That why I got Bertie. C. There are many other dogs like Bertie. D. They want to touch him and this makes them try harder to move their arms. E. Joanne's visits are very important to all her patients. F. Others are too friendly. G. Of course, not everyone likes dogs. H. They also arranged to move him to a different bed.
