B:两地都有各种各样的物种。
C:两者在保护沿海岛屿方面发挥着重要作用。
D:他们俩都受到附近土地侵蚀的威胁。
【判定题型】:根据题干问法“why …… ”,题目询问“xxxxxx”(文章引用内容)的修辞目的,可以判断本题为修辞目的题。
【关键词定位】定位到Passage 4,原句为“Indeed, they have been called the marine version of the tropical rain forest, rivaling their terrestrial counterparts in both richness of species and biological productivity。”。
【引用内容分析】说明二者可以相比是因为物种都很丰富。
【选项分析】
A:Both are located near the Indian and western Pacific Oceans.A选项只是说了地理位置,并没有说出表明了物种很丰富。错误
B:Both are home to a wide variety of species。提到物种丰富,与原文相符,正确。
C:Both play an important role in protecting coastal islands.这是物种多了之后的一个影响,错误。
D:Both are threatened by the erosion of nearby land.只是说了珊瑚受到的威胁之一,与比较目的无关。错误
