问题    The debate over whether dogs or cats make better pets was given a new dimension recently, and dogs seem to have come out the【C1】______(win). According to new research, dogs, more than cats or other pets, are【C2】es______ good for people’s health and can help them live longer lives.

   In an article for the British Journal of Health Psychology, Dr. Deborah Wells of Queen’s University in Belfast, Northern Ireland, reviewed dozens of studies on the health【C3】be______of pet ownership. She found that all pets helped their owners to be healthier, and that dog-owners were particularly better off. " It is possible that dogs can directly【C4】prom______our well-being by buffering us from stress, one of the major risk factors associated with ill-health," writes Wells. "The stay with a dog can also lead to increases in physical activity and facilitate the development of social contacts, which may【C5】 enh______both physiological and psychological human health in a more indirect manner.
   In addition to keeping people healthy and helping prevent illness, it was found that dogs can aid in【C6】rec______. For example, dogs have been shown to have a calming influence on people suffering from heart disease, high cholesterol or Alzheimer’s. Citing one study, Dr. Well explains that heart-attack victims are 9 percent【C7】______likely to be alive a year after their episode if they own a dog. Dogs have also been found to help warn owners of oncoming heart attacks or diabetic shock. In some【C8】c______dogs have even helped revive coma patients. For these reasons, the use of therapy dogs in many hospitals and【C9】______(retire)homes is becoming more popular. Although scientists still do not have【C10】______(conclude)data as to why dogs play such a major role in the health of their owners, the evidence all seems to point in the same direction. Dogs may provide more than just companionship, including the key to a longer life.
