藍洞位于塞班島的東北角，是塞班最著名、難度最高、曾被《潛水人》雜志評為世界第二的洞穴潛水點。今天，就讓我們一起遨游藍洞吧。

The blue hole in the northeast corner of Saipan is a natural cave connected to the PacificOcean. The geology of this area is 1）limestone made from 2）coral 3）reef. The most amazing thing about the blue hole is a deep hole formed because the limestone has 4collapsed and been 5）eroded by seawater. It is filled with dark blue sea water through the three waterwaysat the bottom of the cave. The waterway can reach the open sea， so the blue hole pool can show blue light. This is how the famous blue hole took shape. Blue Cave was named the second largest cave dive in the world by DiveMan magazine. You enjoy diving here.

位于塞班島東北角的藍洞是與太平洋相連的天然洞穴，地質(zhì)是由珊瑚礁形成的石灰?guī)r。藍洞最神奇之處，就是石灰?guī)r經(jīng)過海水長期崩塌、侵蝕，形成一個深洞，海水透過洞底3個水道，將深洞灌滿了深藍色海水，水道能通到外海，所以藍洞水池內(nèi)能透出淡藍色的光澤，著名的藍洞就是這樣來的。藍洞被《潛水人》雜志評為世界第二的洞穴潛水點。喜愛潛水的你能在這里得到極大的享受。

2.“a huge underground cave whose spherical roof can even accommodate achurch”是一個定語從句，可以使表達更加清晰。

塞班島上有十多個潛水勝地，其中翅灘有著大量章魚出沒; B-29 潛水點則有著一架日本水上轟炸機、機關(guān)槍塔樓和爬滿了珊瑚的發(fā)動機;黑珊瑚潛水點有著大量受到高度保護的黑珊瑚，一小群特有的海豚在這片水域巡游，為那些想去這片特殊水域的潛水者指引方向。

藍洞里面還有兩個天然的游泳場，通過海底通道連接外部海洋。對于潛水者來說，這將是一次無以倫比的體驗。
