【简答题】
Dear Mary : Thank you for your last letter. I’m happy to know that you will spend your holiday in Hawaii(夏威夷)this summer .You said you wanted to know something about Hawaii. Hawaii has always been a magic name to people who like travelling because of the scenery(景色) .People from all over the world dream of seeing the beautiful islands. It’s always one of their dreams to watch the sun going down. At weekends , my family and I often watch the sunset at the seaside. It’s really exciting. Hawaii is a fun place to go. Long long ago, the first people went to Hawaii in a small boat . They found the place quite beautiful. But it was difficult for travelers to go to Hawaii at that time. And there were no big hotels like the ones today. Now things have changed. Lots of nice big hotels have been built in recent years. However, the nice view in Hawaii hasn’t changed much. In the morning , many tourists often take a walk along the water in. At night , they get together to hold parties, chatting and dancing. Now , you see Hawaii is really a good place to visit. I’m looking forward to seeing you soon. Yours Kate Answer the following questions with No More Than 4 Words 小题1:Where will Mary spend her holiday this summer ? 小题2:Why has Hawaii been a magic name to people who like travelling? 小题3:What do Kate and her family often do at the seaside at weekends? 小题4:How did the first people go to Hawaii long ago? 小题5:Who often get together to hold parties, chatting and dancing at night ?
