Alaska is perhaps the most amazing state in the USA. It has coastlines facing both the Arctic Ocean and the Pacific Ocean. This state has an incredible three million lakes. That’s four lakes per person living there. Many cities in Alaska cannot be reached by road, sea, or river. The only way to get in and out is by air, on foot, or by dogsled. That’s why Alaska has the busiest sea airport in the world, Lake Hood Seaplane Base. Nearly two hundred floatplanes take off and land on the water of this airport every day. It’s really a fun scene to watch. Alaska is called the Land of the Midnight Sun because in summer, the sun does not set for nearly three months. But in winter the sun stays almost unseen. All Alaskans take special pride in their beautiful and unique state. 1.Alaska ______________.
