听力原文： More than 50 percent of all homes in the U.S. have one thing in common; people living in them keep one or two small animals as pets. In fact there are more pets in the U.S than children. Why？
Researchers have been attempting to find the scientific answer to this question. Much has been written about how animals, violent crimes, and about how they help children deal with emotional problems.
Last year researchers met at the America's National Institute of Health. They found there is a lot of evidence that animals may be helpful to human health. But they agreed more work is needed to show and measure these facts in a scientific way.
Recent studies have confirmed an animal coming effect. For example, a research at a government laboratory near Washington examined how animals influence blood pressure and heart rote. The study involves 92 students. All were in good health. Each one met with a dog whom they did not know but who was friendly. The students were permitted to touch or hold the dog. The researchers measured the students' blood pressure and heart ram before and during the meeting. The results showed an overall drop in blood pressure and heart rate after the students talked to the dog. The researcher said the same effect often takes place in the animal itself..
Other students have shown that different people react differently to animals. The good effects of pets on physical and mental health may be linked to a person's position within a social; or economic group.
Researchers say they still do not fully understand the physical changes that take place when humans and animals are together, but they say it is clear that animals fill a human need. Animal pets don't reject people because they are sick or disabled. As a result, they may provide the sick or the disabled with a better sense of security.

1 Despite Denmark's manifest virtues, Danes never talk about how proud they are to be Danes. This would sound weird in Danish. When Danes talk to foreigners about Denmark, they always begin by commenting on its tininess, its unimportance, the difficulty of its language, the general small-mindedness and self-indulgence of their countrymen and the high taxes. No Dane would look you in the eye and say "Denmark is a great country." You're supposed to figure this out for yourself.
2 It is the land of the silk safety net, where almost half the national budget goes toward smoothing out life's inequalities, and there is plenty of money for schools, day care, retraining programs, job seminars -- Danes love seminars: three days at a study center hearing about waste management is almost as good as a ski trip. It is a culture bombarded by English, in advertising, pop music, the Internet, and despite all the English that Danish absorbs -- there is no Danish Academy to defend against it -- old dialects persist in Jutland that can barely be understood by Copenhageners. It is the land where, as the saying goes, "Few have too much and fewer have too little," and a foreigner is struck by the sweet egalitarianism that prevails, where the lowliest clerk gives you a level gaze, where Sir and Madame have disappeared from common usage, even Mr. and Mrs.. It's a nation of recyclers -- about 55% of Danish garbage gets made into something new --and no nuclear power plants. It's a nation of tireless planners. Trains run on time. Things operate well in general.
3 Such a nation of overachievers -- a brochure from the Ministry of Business and Industry says, "Denmark is one of the world's cleanest and most organized countries, with virtually no pollution, crime, or poverty. Denmark is the most corruption-free society in the Northern Hemisphere.' So, of course, one's heart lifts at any sighting of Danish sleaze: skinhead graffiti on buildings ("Foreigners Out of Denmark!"), broken beer bottles in the gutters, drunken teenagers slumped in the park.
4 Nonetheless, it is an orderly land. You drive through a Danish town, it comes to an end at a stone wall, and on the other side is a field of barley, a nice clean line: town here, country there. It is not a nation of jaywalkers. People stand on the curb and wait for the red light to change, even if it's 2 a. m. and there's not a car in sight. However, Danes don't think of themselves as a waiting-at-2-a, m.-for-the-green-light people -- that's how they see Swedes and Germans. Danes see themselves as jazzy people, improvisers, more free spirited than Swedes, but the truth is (though one should not say it) that Danes are very much like Germans and Swedes. Orderliness is a main selling point. Denmark has few natural resources, limited manufacturing capability; its future in Europe will be as a broker, banker, and distributor of goods. You send your goods by container ship to Copenhagen, and these bright, young, English-speaking, utterly honest, highly disciplined people will get your goods around to Scandinavia, the Baltic States, and Russia. Airports, seaports, highways, and rail lines are ultramodern and well-maintained.
5 The orderliness of the society doesn't mean that Danish lives are less messy or lonely than yours or mine, and no Dane would tell you so. You can hear plenty about bitter family feuds and the sorrows of alcoholism and about perfectly sensible people who went off one day and killed themselves. An orderly society cannot exempt its members from the hazards of life.
6 But there is a sense of entitlement and security that Danes grow up with. Certain things are yours by virtue of citizenship, and you shouldn't feel bad for taking what you're entitled to, you're as good as anyone else. The rules of the welfare system are clear to everyone, the benefits you get if you lose your job, the steps you take to get a
