　　Jane went to Scotland(苏格兰)for her holiday. Two days ago, she sent a letter and a postcard to her family.

　　Jane said in her letter, “I visited a lot of places. How are you all? I miss you very much. I went to Edinburgh(爱丁堡)by train. I stayed there for three days and then I went to the mountains. I met a lot of young people there and now they are my friends. I also saw many famous lakes. I find that Scotland is more beautiful than England(英格兰). And the restaurant is very nice. I’m having a wonderful time here now. ”
