英语四级等于公共英语的PETS的几级

D

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer. Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their ani mal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

Leading a dog’s life in America isn’t such a bad thing. Many grocery stores sell pet foods to owners eager to please their pets. In Houston, Texas, dogs can have their dinner delivered to their homes, just like pizza. Well-to-do canines can attend doggy daycare centers while their owners work. Pets can even accompany their owners on vacation. Fancy hotels are beginning to accommodate both man and beast. Furry guests in hotels can enjoy gourmet meals served on fine china and sleep in soft beds.

Beneath the furry luxuries, there lies a basic American belief: Pets have a right to be treated well. At least 75 animal welfare organizations exist in America. These provide care and adoption services for homeless and abused animals. Vets can give animals an incredible level of medical care for an incredible price. To pay for the high-tech health care, people can buy health insurance for their pets. And when it’s time to say good -bye, owners can bury their pets in a respectable pet cemetery.

The average American enjoys having pets around, and for good reason. Researchers have discovered that interacting with animals lowers a person’s blood pressure. Dogs can offer protection from burglars and unwelcome visitors. Cats can help rid the home of unwanted pests. Little creatures of all shapes and sizes can provide companionship and love. In many cases, having a pet prepares a young couple for the responsibilities of parenthood. Pets even encourage social relationships: They give their owners an appearance of friendliness, and they provide a good topic of conversation.

Pets are as basic to American culture as hot dogs or apple pies. To Americans, pets are not just property, but a part of the family. After all, pets are people, too.
