　　Travel

　　A succession of beautiful scenery makes one feel delighted. A long stay in the same surroundings to make everything the same. Routine work often makes one feel bored But if you take a trip or a long journey on your holidays to some scenic spots or historic sites, that will make great difference.

　　Travel can widen one’s knowledge. The farther you go, the more you will learn about different politics, economics, customs as well as geography. If you travel the whole world some day, you will fully understand the globe on which we live.

　　However, too much travel causes tiredness. You get on a bus or a taxi, you travel on the train or in a plane, being patient with the hours needed on your mute from one place to another, that will make you exhausted after a while.
