Question

【题目】Every year gray whales swim a 10,000 miles round-trip, from the cold waters near Alaska, down the coast of North America to the warm waters near Mexico, and back again. It is one of the longest migrations (迁徙) of any mammal (哺乳动物).

All day, all summer long, in the cold waters near Alaska, gray whales eat and eat.

Instead of teeth, gray whales have baleen (鲸须) they use to get food from ocean water. They get big mouthfuls of muck (淤泥) from the ocean floor, then push that muck right back out through their baleen. The mucky water flows through, but tiny animals get trapped in the baleen and licked up.

When the water starts to freeze, the whales begin their long trip south. They swim night and day, without stopping to eat or rest. During the long journey, migrating whales may push their heads out of the water to see where they are.

Two months later, the whales reach Mexico. Babies are born here in warm, shallow (浅的) waters called lagoons (濒海湖). Ocean lagoons have no food for the adults, but the babies are safer here than in the open seas. All winter the babies grow big and strong.

In spring first the dads and teenagers leave the lagoons, then the moms with babies. Migrating gray whales swim close to shore, especially moms with babies. The ice is melting up (融化) north, and it’s time for the hungry whales to make the long journey back to their summer feeding grounds.

【2】D

【3】A

【4】B

【解析】文章介绍了每年灰鲸都要历经两个月的时间进行迁徙。

【1】词义猜测题。The mucky water flows through, but tiny animals get trapped in the baleen and licked up.这句话的意思是泥水从嘴里流出，但是被困在鲸须中的小动物被吃光了，选A。

【2】细节理解题。根据They swim night and day, without stopping to eat or rest.可知在它们到墨西哥的漫长迁徙中，灰鲸不停歇地游到濒海湖，选D。

【3】细节理解题。根据Babies are born here in warm, shallow (浅的) waters called lagoons (濒海湖).可知灰鲸妈妈在靠近墨西哥的温暖浅水中孵化小鲸鱼，选A。

【4】细节理解题。文中讲到了灰鲸如何获取食物，它们什么时候返回阿拉斯加州以及它们游多久可以到达墨西哥，但是并没有提到灰鲸的寿命，故选B。
