PAT THE DOG Did you know there are some very special dogs doing good work in our hospital wards? These are PAT (Pets As Therapy) dogs. Doctors and nurses are recognising the benefits of pets more and more — particularly for children, people with mental illnesses and elderly people who are separated from their own pets or have had to give up their pets. Stroking and playing with a pet is a calming experience and something to look forward to. One hospital reported that a man with a mental illness, who hadn't spoken for years, first stroked and played with a visiting dog and then started talking to it. Today, around 4,500 dogs and 50 cats and their volunteer owners are at work in the UK bringing comfort and pleasure to over 100,000 people in hospital. There are many other ‘working dogs’. There are guard dogs, police dogs, hunting dogs and dogs for the blind. Disabled people benefit greatly. Take the case of Alan Smythe, who has to visit hospital every month. Some things are difficult for him because he is in a wheelchair. But his life has altered dramatically since he got a dog, Tess, from the charity 'Dogs for the Disabled'. ‘She helps me to get dressed, and she brings me my socks and shoes. She fetches the newspaper from the shop, and she passes me the phone when it rings. I feel so much better too. It's like having a really good friend. She comes with me to hospital. Once, she saved my life. I am a diabetic and one day my blood sugar level dropped, and when I was going into a coma she went next door and she alerted my neighbour. He gave me an insulin injection. 1．Which of the following statement is TRUE according to the passage?
