相信大家都明白这样一个道理：想要学好英语，必须不断的，大量的吸收和积累，那么雅思阅读无疑是这样的一种“输入”过程，因此，小编每天会根据剑桥真题中阅读的主题为大家节选一段相关文章，并作相关注解，希望对大家的词汇句型积累有所帮助。今天，我们来看下雅思阅读拓展之蓝鲸。
Blue whales reach these mind-boggling dimensions on a diet composed nearly exclusively of tiny shrimplike animals called krill. During certain times of the year, a single adult blue whale consumes about 4 tons (3.6 metric tons) of krill a day.
Blue whales are baleen whales, which means they have fringed plates of fingernail-like material, called baleen, attached to their upper jaws. The giant animals feed by first gulping an enormous mouthful of water, expanding the pleated skin on their throat and belly to take it in. Then the whale's massive tongue forces the water out through the thin, overlapping baleen plates. Thousands of krill are left behind—and then swallowed.

二、 长难句解析：
1. Blue whales reach these mind-boggling dimensions on a diet composed nearly exclusively of tiny shrimplike animals called krill.
蓝鲸的饮食达到了令人难以置信的维度，它的饮食几乎都由这种微小的叫做磷虾的虾体动物所组成。
在这句话中，主语是Blue whales，reach是谓语，宾语是dimensions on a diet，composed nearly exclusively of tiny shrimplike animals called krill是后置定语，修饰diet。
2. Blue whales are baleen whales, which means they have fringed plates of fingernail-like material, called baleen, attached to their upper jaws.
蓝鲸是须鲸类动物，这也就意味着它们有类似于指甲物质的须状物，这个叫做鲸须，鲸须附着于它们的上颌上。
这句话中，主句是Blue whales are baleen whales，which引导的非限修饰这整句话，后边的“called baleen, attached to their upper jaws”是两个并列成分，都修饰fringed plates这个东西。
