Their population is tinyless than 350and continues to shrink.【C1】_Yet for scientists and co
3、nservationists anxious about the future of these creatures, rays of hope are beginning to pierce an otherwise gloomy horizon. Thanks to a surge of scientific research and new tools for conducting it, they expect to learn far more about right whales, their interaction with the environment, and how to
4、 better protect them from their biggest threat: man.【 C2】_For the right whales, the leading causes of mortality are collisions with ships and encounters with fishing gear, researchers say. Females appear to have the toughest time surviving the range of human and natural threats. Its these challenges
5、 scientists hope to address with a growing momentum in right-whale research.【C3 】_ Conservationists are working with governments and the shipping industry to move or control traffic on heavily used sea lanes that ships and whales share.

6、o the impact of factors ranging from water quality to shifts in climate.“Im not much of a Pollyannaj 1 can be very grumpy about the progress of right-whale biology and conservation,“ says Scott Kraus, director of research at the New England Aquarium in Boston.

7、oing to see a tremendous burst of very creative scientific energy“ applied to fundamental biological and ecological questions surrounding the whales. “When those questions get answered, we re going to have very specific ideas about what management strategies will reduce mortality and perhaps enhance
8、 reproduction,“ he says.【C4 】_ In principle, preventing “two female deaths a year would have a major impact on the prospects for the population,“ says Hal Caswell, a marine zoologist at the Woods Hole Oceanographic Institution in Woods Hole, Mass.【C5 】_From 1500 to 1600, Basque whalers decimated rig
9、ht-whale populations in the eastern Atlantic, taking an estimated 25,000 to 40,000. In the late 1600s, by some accounts, it would have been possible to walk across Cape Cod Bay on the backs of whales. But by the mid-1700s, New Englanders had taken another 3,000, Mr. Kraus says. By the early 20th cen
10、tury, “only a few dozen whales survived in the western North Atlantic“.AIf they can save a population this small, then it could boost hopes of saving other species from the unintended impact of humans on the environment.BYet achieving that means untangling a web of intertwined human and environmenta
11、l factors that contribute to the whales plight. The one factor that weighs most heavily is human.CIn addition, researchers are exploring a number of acoustic approaches to avoiding ship-whale collisions. One technique scientists hope to test later this month involves the use of moored buoys that use
12、 passive sonar systems to listen for whales.DTo an outsider, the goal looks deceivingly within reach. The population is so small that it would take only modest pains in saving whales to help turn the situation around.EThat population had slowly rebuilt. Over the past 20 years, researchers have built
13、 an impressive collection of 250,000 photosa catalog of some 460 North Atlantic right whales. Each animal bears unique growths of hardened skin, or callosities, in places where hair would appear on humans. The callosity patterns act as visual tags, allowing researchers to follow the whales life hist
14、ory.FLater this month, for example, researchers are set to test new approaches to tracking the elusive whales in hopes of alerting ships to their presence. Meanwhile, chemists and engineers are developing whale-friendly commercial-fishing gear.GBy some estimates, if current population trends hold, t

16、 of the blanks.For Bill Gates, Warren Buffett and many Wall Street number-crunchers, the dollar supplied one of the nastiest surprises of 2005. The worlds two richest men and most financial-market seers predicted that the greenback would fall last year, dragged down by Americas colossal current-acco
17、unt deficit. Many forecasters were predicting that the euro would buy $ 1. 40-odd by now and that a dollar would fetch less than ¥ 100.【C1 】_ Against the euro and yen, the greenback did even better. It ended the year at $ 1. 18 per euro, up by 14%. Despite a wobble in December, the dollar made a sim
18、ilar advance against the yen.Not surprisingly, the pundits are more cautious about 2006.
