While the word “island” will have you think of beaches, the sun and sand, there are some islands where you’ll find that the perfect sunshine is covered by clouds of mystery.
Easter Island
Easter Island is located midway between Chile and Tahiti. Land on it and you’ll instantly be attracted by the sight of big sculptures（雕塑）, 14 feet tall, and weighing 14 tons each. Known as the moai, these ancient sculptures have been made out of volcanic rock（火山岩）. For years, people have have no idea why the ancient locals decided to build them.
Seychelles
The Seychelles is a group of 115 islands located in the Indian Ocean, off the eastern coast of Africa. At least half of these islands are preserved as national parks. They are home to the coco-de-mer, a big plant which produces the world’s largest seed and leaf, and are also home to many rare animal species.
Surtsey Island
The Surtsey Island is at the southernmost point of Iceland. It didn’t exist before 1963. Then an undersea volcano erupted（爆发）, which reached the surface and began forming this island. The volcanic activity continued till 1967, at which point a 2.7 sq km piece of land was formed. Since then, wave has continually affected the island, reducing its size, which as of 2002 was only 1.4 sq km.
Isola La Gaiola
Off the coast of Naples, Italy, you’ll find the Isola La Gaiola, which actually consists of two small islands linked together by a bridge. This island is beautiful. Yet, if you were to call out “hello” here, you would hardly get an answer, as it is completely abandoned now with only some swimmers or adventurers who occasionally set foot on it.
