A.My house. B.In London. C.It’s small. 答案：【答案】C【解析】【原文】略When Lady Gaga releases a new single, it quickly goes around the world. Now scientists have discovered the same thing happens with the songs of another unusual and interesting creature – the humpback whale. The mammals become interested in new tunes just like people do, and the most popular original whale songs spread globally like hit singles. The discovery has astonished experts who say it is the first time such a large, “population-wide cultural exchange” has been seen in the animal kingdom. Male humpback whales are well-known for the loud, long and complex songs they make during the mating season. Scientists are unsure why the males sing. Some believe it is a way of advertising themselves to females, others that it allows migrating(迁徙)whales to stay in contact. Each song lasts for 10 to 20 minutes and the males can sing continuously for 24 hours. At any period of time, all the males in a population sing the same song. But a study, published in the journal Current Biology, shows that this song changes over time and spreads around the oceans. Dr Ellen Garland, of Queensland University, said: “Our findings show cultural exchange on a vast scale. Songs move like cultural ripples from one population to another, causing all males to change their song to a new version.” Researchers recorded songs from six neighboring populations of whales in the Pacific over a decade. They found that new versions of the songs appear over time and always spread from west to east. It takes around two years for songs that appear in the waters off Australia to be heard in French Polynesia. Dr Garland believes that a small number of whales may migrate to other populations carrying the new songs with them, or that they are heard by passing whales. Dr Garland said, “We think this male search for song novelty(新颖)is in the hope of being that little bit different and perhaps more attractive to the opposite sex.” 63.
