    Eliza：I love travelling by train best! It's very exciting. I travelled most of Europe in 5 months by train. It's the best way to talk with the local people and make new friends on the way. Trains make the long trip enjoyable. The train ride to me is just like a big moving party.

    I also like travelling by ship. It is a very great way to spend a holiday. I can go to parties and watch movies on the ship，and enjoy the blue sky and water.
