Some people associate migration mainly with birds. Birds do travel vast distances, but mammals also migrate.
An example
is the caribou, reindeer that graze on the grassy slopes of northern Canada. When the weather turns cold, they travel south until spring. Their tracks are so well-worn that they are clearly visible from the air. Another migrating mammal is the Alaska fur seal. These seals breed only in the Pribilot Islands in the Bering Sea. The young are born in June and by September are strong enough to go with their mothers on a journey of over 3, 000 miles. Together they swim down the Pacific Coast of North America. The females and young travel as far as southern California. The males do not journey so far. They swim only to the Gulf of Alaska. In the spring, males and females all return to the islands, and there the cycle begins again. Whales are among the greatest migrators of all. The humpback and blue whales migrate thousands of miles each year from the polar seas to the tropics. Whales eat huge quantities of plankton. These are most abundant in cold polar waters. In winter, the whales move to warm waters to breed and give birth to their young. [br] Which of the following is NOT true?
选项
A、Whales breed in winter.
B、Young whales are given birth in cold waters.
C、Alaska fur seals give birth to the young only in one area.
D、Alaska fur seals are born in warm weather.
答案
B
解析
是非题型。见文章最后一句:In winter,the whales move to warm waters to breed andgive birth to their young.因此选项B为答案。
