【正文】 widowers (鰥夫 ) were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man’s life and two to a woman’s. The effect holds for all causes of death, whether illness, accident or selfharm. Even if the odds are stacked against you, marriage can more than pensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn’t smoke. There’s a flip side, however, as partners are more likely to bee ill or die in the couple of years following their spouse’s death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social works have similar effects. So how does it work? The effects are plex, affected by socioeconomic factors, healthservice provision, emotional support and other more physiological (生理的 ) mechanisms. For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner. A life partner, children and good friends are all remended if you aim to live to 100. The ultimate social work is still being mapped out, but Christakis says: “People are interconnected, so their health is interconnected.” 66.

D All Eskimos live most of their lives close to sea or fresh water. They may follow game inland for several hundred miles, but they always return to the shores of rivers, lakes, or seas. Eskimo land has a bare look. Large rocks, pebbles, and sand cover much of the surface. Plants called lichen (地衣 ) grow on the rocks, and where there is enough soil, grass, flowers, and even small bushes manage to live. No trees can grow on Eskimo land, so geographers sometimes call it the Arctic plains. There are some animals in Eskimo land, such as rabbits, which eat the plants. Other animals, like the white fox and the gray wolf, eat the rabbits. The Eskimo is a meateater, too, and may even eat a wolf when food is scarce. The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall are almost too short to be noticed. Summer is the best time, as food is usually plentiful. But it is also the time when Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store, for seldom can enough animals be killed in winter to feed a family. The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21st and August 21st the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sunshine at all. Around Oct. 21st the Eskimos of Northern Greenland see the sun set directly south of them, and they don’t see it again until February 22nd. All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker. Winter nights in the Far North are seldom pitchblack. As in the rest of the world, the stars and moon provide a little light. The northern lights also help the Eskimo to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo’s eyes. 71. Which of the following statements is NOT true? A. Eskimos do not usually eat wolves. B. Eskimos like to chase one another. C. Eskimos depend heavily on water. D. Eskimos a
