四、阅读理解
Blue whales are the largest animals ever known to have existed 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 are 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,whaling severely reduced the whale populations.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 a fiigration
B.dying out due to commercial whaling
C.moving from the south to the north
D.rarely found in the Southern Pacific

3.The underlined word “cetaceans” in paragraph 5 probably means “”.

B.whale species
C.ocean conditions
D.migration patterns
“Toidentifythebluewhales,theresearcherslookedatphotosofcetacea nstakenintheNorthPacificOcean...”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?
mercial whaling.
B.Weather conditions.
C.Life reproduction.
D.Food resources.
buttheysuspectthatthewhalesmaybefollowingtheirfoodmovingfarther north可知,研究者怀疑蓝鲸有可能跟随着它们的食物向北移动。
