阅读理解 Dogs in the classroom lower stress of primary school students, new research has found. The study by UK researchers found spending some time with a dog twice a week was better for reducing stress on students than many other classroom relaxation activities. And the benefits of these "dog dates" were similar for children in both normal and special schools. Stress is known to negatively affect a child's learning, behaviour, health and mood. This has led schools to try a number of ways to reduce stress, including yoga, mindfulness, physical activities and even having animals in classrooms. The researchers from the University of Lincoln measured students' stress levels by tracking the level of the stress in their saliva (唾液). They studied 105 students aged 8 to 9 in four normal schools as well as 44 children of a similar age in seven special schools in the UK. The children were randomly (任意) divided into three groups: a group that spent time with a dog; a group that spent time doing relaxation activities; and a "control" group that did neither of these things. Students in the dog group spent 20 minutes with a trained dog twice a week for four weeks. The relaxation group spent the same amount of time doing exercises. The researchers found that the children in the dog group had "significantly lower" stress levels, while those in the relaxation and control groups recorded an increase over the school term. The study, which was published in the journal PLOS ONE, also found stress was lowest in the children in the dog group immediately after their contact with the puppies. "Dog-assisted activities can lead to lower stress levels in schoolchildren with and without special educational needs," University of Lincoln researcher Kerstin Meints said, "but more research is needed to discover what was the ideal amount of time and contact with dogs for the best effect." （1） What is the benefit of having dogs in the classroom according to the research?
