C

ANTARCTIC FISH

Have you ever wondered how some fish can live in icy cold waters without freezing? Scientists have made recent discoveries that help explain how the Antarctic cod (南极鳕鱼) is able to live in the freezing waters off the coast of Antarctica.

The key word is ice.

That describes the ocean around the edges of Antarctica. Far from land, a giant shelf of ice meets the ocean. At the underside of the shelf, mud and pieces of ice provide a home to a world of algae (藻) and tiny animals. In that icy world there also lives a small fish, the Antarctic cod.

For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work, and research has been slow in solving the problem. Now it seems we have an answer.

Research was begun by cutting holes in the ice and catching the fish with hook and line. Scientists studied the fish’s blood and measured its freezing point, the temperature at which ice crystals (晶体) just begin to form.

The fish were taken from seawater that had a temperature of 28.6 degrees Fahrenheit (F) and many ice crystals floating in it. The blood did not begin to freeze until its temperature was lowered to 28.3 degrees F [Water freezes at 32 degrees Fahrenheit (32°F)]. That small difference is enough that the fish can live at the freezing temperature of the ice-salt mixture.

The scientists’ next research job was clear: Find out what kind of stuff in the fish’s blood kept it from freezing. Their research led to some really mysterious stuff made up of a protein (蛋白质) never before seen in the blood of a fish. When this stuff was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze character and a lowered freezing point.

Passage 73

D

　 “Regardless of social class, race and age, men say they hate to shop,” says Zukin, City University of New York sociology professor. “Yet when you ask them deeper questions, it turns out that they like to shop. Men generally like to shop for books, music and hardware. But if you ask them about the shopping they do for books or music, they’ll say, ‘Well, that’s not shopping. That’s research.’ “

　 In other words, what men and women call “buying things” and how they approach that task are different.

　 Women will wander through several 1,000-aquare-meter stores in search of the perfect party dress. Men will wander through 100 Internet sites in search of the perfect digital camcorder(摄录像一体机). Women see shopping as a social event. Men see it as a special task or a game to be won.

　 “Men are frequently shopping to win,” says Ann, a marketing professor at Loyola University of Chicago. “They want to get the best deal. They want to get the best one, the latest one and if they do that it makes them happy.” When women shop, “They’re doing it in away that they want everybody to be very happy,” says Ann. “They’re kind of shopping for love.”

　 Teenage girls learn to shop from their moms and older sisters, but they also learn to shop by examining articles in magazines like Seventeen,” City University Zukin says. “And although men’s magazines such as GQ and Esquire have long had shopping articles, it’s TV that has the eye of young male shoppers,” say Ann and Zukin.

　 “Television shows are used by young men in the same way Seventeen magazine or Lucky is used by girls,” says Zukin, “to help make clothing and toiletry(化妆品) choices.”

　 “Of course, there are men who love to shop and are proud of it,” Loyola’s Ann says. And that is important no matter whether you buy a car or a frying pan. All men love to buy but don’t want to get cheated. Ann adds, “There actually are men who are interested, for example, in cooking or shopping or chinaware or things around the home-----they become kind of girl magnets. Women like it.”
