     The holiday is upon us. Finally, after months of study, you have some time to yourself. So, why not read

a book? Well, some people will say, "Why bother with books? We have the Internet that offers a lot of more

colorful fun. Books are history!" But don't be fooled. I'm sure there's still a lot to be said for reading.

     One clear reason is that a well-chosen book can give you a lot of wonderful vocabulary, so long as you

have a good dictionary, of course. Believe me, it's far easier to get new English words and phrases from a

book or an article than it is from the TV or the Internet.

     But another more important point is that books give you something that the Internet simply can not. The

average webpage is picture-heavy and the text is often designed to make it as easy to read as possible. While

"easy" may attract you, unfortunately it's of little use for any long-term development of reading skills and the

general language level. Because of that, reading on the Internet cannot take the place of reading books.

     But perhaps the best single reason is that simply choosing what you read and doing it independently means

that it's something you do by and for yourself. You can choose what you want to read. It's hard work, but

somewhere down the line, you'll find that what once seemed like a duty is now a pleasure.
