My friend a globe-trotter, that is, he goes abroad frequently. He is an airline pilot and he has visited many counties around the world. Whenever he returns home, he tells me stories about his adventures. He has seen the Himalayas and the Alps as well as the Amazon rain forests and the Sahara Desert. He's seen Bengal tiers Australian kangaroos and the storts of Holland, too.
My friend has been to many places, but I have never actually traveled beyond the borders of my own country. As long as I remain a teacher, I can't expect to do much traveling. I spend most of my time at school, preparing lessons, teaching and marking examinations. As soon as school over each year, however, I do take a brief vacation and journey to some part of my country that I've not seen before.
Unless I win a big lottery prize I doubt that I will every go to Australia or Africa or Latin America. But in another sense, I've already seen those places and many more besides. How have I done this? The answer is smple: book: Thanks to books; I have visited the far corners of the globe. Moreover, I have joumeyed through time as well as through space. I can read books, for example, about people and places in contemporary times. I can also read books about people and places in ancient times. As an airline pilot, my friend has seen the world in one way. As a reader. I have seen it in another way---between the covers of books
