BDDA解析文章向我们描绘了珊瑚礁的形成情况以及对珊瑚礁的保护。1.主旨大意题。通读前文可知文章是呼吁大家保护珊瑚礁。2.推理题。根据第四段第一行A reef grows only about as fast as your fingernails—three-quarters of an inch a year。可知珊瑚礁的形成非常难，要形成一个珊瑚礁需要很多年。3.推理题。举这个例子就是想告诉大家破坏珊瑚礁是很容易的。4.推理题。根据最后一段There is hope, too, that people will learn to be good partners to the reefs.可知作者还是比较乐观的。
