                                                                 Traveling 

     It is exciting to visit different places. As you travel, you will admire the beauty of nature. Besides, you

can make friends with people from different places. Finally, you can get to know the culture and enjoy the

delicious food. Today people are so fond of traveling that tourism has become one of the faster growing

industries in most countries.

     The main reason why people travel is, perhaps, to relax. For example, having worked hard throughout

the weekdays, people will find a trip to the nearby mountains or beaches for a real relaxation. For another

example, spending a holiday traveling abroad is an especially satisfying experience for those who do not

have much of an opportunity to be away from their homelands. When people return from their travel, they

will generally feel fresh and energetic, ready to work harder.

     Traveling is also one of the best means for learning and broadening your views. You may have read or

heard about something but you can never get an accurate picture of it until you see it for yourself. Seeing

is believing. Furthermore, if you are a careful observer, you can learn much during your travel about the

geography, biology, and history of the places you visit. No matter how well educated you are, there is

always a lot for you to learn through traveling. The knowledge acquired from travel, as you will have found

in your life, is no less valuable than that from any influential reference book.

Questions:

1. What's the main reason why people travel?

    ____________________________________________________.

2. How do people feel when they return from their traveling?

    ____________________________________________________.
