Traveling is very interesting. Many people love traveling. There are many ways to travel: by plane, by train, by ship or by car. Everyone has their favorite way.

    Greg: My favorite way of traveling is by car. I can bring my pet dog along. I can travel three hundred miles or only fifty miles a day. I can stop at a good restaurant to enjoy a good meal or at a hotel to spend the night.

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

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

    Danny: Planes are my favorite. It's the fastest way of traveling. I can quickly get to another country. Planes have very comfortable seats. I can have something to drink and to eat. I can also read some free magazines and newspapers.

穿井得一人

    宋之丁氏，家无井而出溉汲，常一人居外。及其家穿井，告人日：“吾穿井得一人。”有闻而传之者：“丁氏穿井得一人。”国人道之，闻之于宋君。宋君令人问之于丁氏，丁氏对日：“得一人之使，非得一人于井中也。”求闻之若此，不若无闻也。
