| Hawaii is famous for its beautiful beaches. Every year water sports, especially surfing and water skiing attract 1 tourists to the island. Hawaii has been a magical name to people who like travelling 2 many years. People on 3 sides of the Pacific Ocean (太平洋), in Japan and America, dream of 4 these beautiful islands in the middle of 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 5 that you can almost see it move. The sun leaves behind a glow (落日余晖) that lights the sky in the quiet water. People often have a quiet, enjoyable time walking along the water. This scenery is not very different from the exciting beauty that greeted the first tourists to these islands centuries ago. They came in canoes(小木筏) not much 6 than small boats. They found the beautiful white sand beaches and the waving palm trees (棕榈树), but there were no grand hotels like 7 we see today. The fist people came to Hawaii nearly 8 years ago. but skyscraper (摩天大楼) hotels were only built in the 25 years. Now aero planes make it possible to fly to Hawaii for the weekend from Tokyo 9 San Francisco. 10 people come from, they really want to appreciate the earliest beauty of Hawaii. They want to see the lovely beaches and the mountains which are almost hidden by the hotels. | |||
