示范答案：
People need to travel for lots of different reasons. Almost everybody has to travel to work, so they can earn money and provide for their families. If some people lucky, then they will live very close to the place where they work, so they can travel on foot or by bicycle. Sometimes, however, people live very far away, so they must travel by bus, train, car, or even sometimes by plane or boat! Lots of people also travel to see friends and family members, who might live in a different city, or even a different country. But often people just like to travel for fun, to go to somewhere new,or to see a famous tourist site or place of natural beauty.
