Which of the following is true about animals’ migration?

参考解析：

细节理解题。根据第二段“In Africa, large animals, like elephants and zebras, migrate to find food and water. They usually follow the same ways every year”可知，A项表述正确。根据第三段最后一句“In the winter there aren’t any insects, so the birds fly south to southern Europe and Africa.”可知，冬天时，大多数鸟类会飞往南欧和非洲，而不是在夏天，所以B项表述错误；根据第四段最后一句“They travel 50-65 km each day and they travel about 1, 125 km.”可知，有些昆虫每天飞行50至60千米，整个从北到南的飞行过程一共是1125千米，所以C项表述错误；根据第五段第二句“Salmon (鲑鱼) can swim over 20, 000 km in their life.”可知，鲑鱼一生中会游行20000千米，所以D项表述错误。故选A。
