on the planet,and they can grow to a length of 100 feet and weigh more than 330,000 pounds.But recently researchers have found that these whales are on the move and they have migrated from California waters to areas off Canada and Alaska for the first time since commercial whaling ended in 1965.The researchers identified 15 blue whales that had appeared off the coast of British Columbia and the Gulf of Alaska since 1997.Four of these whales were recognised as ones that were once sighted off California shores,suggesting that the whales were returning to an old migration pattern between the coasts.Before commercial whaling began in the early 1900s,blue whales were found widely throughout the North Pacific and California waters.But from the 1920s to the 1960s,the whale population was severely reduced because of whale hunting.Blue whales never recovered in the North Pacific,making sightings in this area rare.However,much larger groups of whales have been observed close to California since the 1970s.The scientists had previously thought that the California population was separate from the population that had historically lived in the North Pacific waters.But the current study shows that whales off the coast of British Columbia and the Gulf of Alaska are likely part of the California population.To identify the blue whales,the researchers looked at photos of cetaceans taken in the North Pacific Ocean and compared them with a library of blue whale pictures taken along the West Coast of the United States and Southern Pacific.Up to now,the researchers are not quite sure why the whales are changing their migration patterns,but they suspect that the whales may be following their food moving farther north by the changes in ocean conditions.1.According to the passage,blue whales are 　　　. A.following the fixed route of migrationB.dying out due to commercial whalingC.moving from the south to the northD.rarely found in the Southern Pacific答案C解析推理判断题。根据最后一段中的“...thewhalesmaybefollowingtheirfoodmovingfarthernorthbythechangesinoceanconditions.”可推出,蓝鲸正从南向北移动。故选C项。2.The whale population in the North Pacific 　　　. A.is different from the California populationB.is probably part of the California populationC.has become the largest group since the 1970sD.has lived there since the 1960s答案B解析细节理解题。根据第四段中的“ButthecurrentstudyshowsthatwhalesoffthecoastofBritishColumbiaandtheGulfofAlaskaarelikelypartoftheCaliforniapopulation.”可知答案选B项。3.The underlined word “cetaceans” in the last paragraph probably means “　　　”. A.land creatures　　B.whale speciesC.ocean conditions D.migration patterns答案B解析词义猜测题。根据最后一段中的“Toidentifythebluewhales,theresearcherslookedatphotosofcetaceanstakenintheNorthPacificOcean...”可知,为了辨认蓝鲸,研究者看在北太平洋拍的有关“cetaceans”的照片,所以“cetaceans”应该指的是鲸类。故选B项。4.What might make blue whales migrate according to the researchers?A.Commercial whaling. B.Weather conditions.C.Life reproduction.  D.Food resources.答案D解析推理判断题。根据最后一段中的“...buttheysuspectthatthewhalesmaybefollowingtheirfoodmovingfarthernorthbythechangesinoceanconditions.”可知,研究者怀疑蓝鲸有可能跟随着它们的食物向北移动。故选D项。五、语篇填空In 1969,there were only 100 South American fur seals and sea lions making their homes along the coastline of the capital of Lima,Peru.They 1.　　　　　　(hunt) almost to extinction here,not only because of the value of their skin,but also because of the threat they posed 2.　　　　　 fishermen as fish hunters. Today,around the Palomino Islands,there are over 8,000 of these marine animals 3.　　　　　　(make) their homes.Much of the success of restoring the fur seal and sea lion population came from local fishermen in the coastal areas of Peru.They stepped up 4.　　　　　　 support these endangered species after the International Union for the Conversation of Nature (IUCU) sounded their alarm bell. Recently,the IUCU detailed how local fisheries have become efficient mangers.“The Fishermen's Union defines the area 5.　　　　　　  each local fishing collective is 6.(economic) dependent and assigns responsibility for these marine resources,explained the IUCU.”In this manner,the fishermen 7.　　　　　　　　 (they) have slowed economic migration from the Peruvian Highlands to 8.　　　　　　　(profit) but illegal marine activities,thus ensuring that the protected area develops well. Much of their 9.　　　　　　(motivate) for marine protection has come from 10.(see) their livelihood through new eyes—that is,they've recognised the rise of traditional fisheries and tourism.And their practice is one of the best practices for area-based conservation. 答案1.were hunted　2.to　3.making　4.to　5.where　6.economically　7.themselves　8.profitable　9.motivation   10.seeing
