For many years , Hawaii has been a magic name to people who like to travel. People on both sides of the Pacific Ocean, in Japan and in America, dream of seeing these beautiful islands in the middle of ocean. Their dreams always include at least on scene of a sunset over the ocean. In the tropical (热带的)lands, the sun drops like a ball of golden fire into the sea. And it drops so quickly that you can almost see it move. The sun leaves behind a glow that lights the skies in the quiet water.

People often have a quiet, peaceful time—perfect for a leisurely walk along the water. This scene is not too different from the dramatic beauty that greeted the first strangers to these islands centuries ago. They were Polynesia people who came from Tahiti in canoes that much bigger than small boats.

They found the beautiful white sand beaches and the waving palm trees, but there were no grand hotels like the ones we see nowadays. The first people came to Hawaii nearly two thousand years ago, but skyscraper hotels were only built in the last 30 years. Now jet airplanes make it possible to fly to Hawaii for a weekend from Tokyo or San Francisco or Los Angeles.

Wherever people come from, they really want to see the original(原始的,最初的) beauty of Hawaii. They want to see the lovely beaches and the mountains called Diamond Head which is almost hidden by the tall hotels.
