The holiday's 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 and other media that offer a lot more colorful entertainment. Books are history!" But don't be fooled. There's still a lot to be said for reading.

One clear reason is that a well-chosen book is a wonderful source of 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 article than it is from the TV or the Internet.

But an even more important point is that books give you something that modern media 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 be attractive, unfortunately it's little use for many long-term development of reading skills and the general language level. For that, there's still no substitute (替代品)of a book.

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 yourself. You can choose what you want to read. It's hard work, but something down the line, you will find that what once seemed like a duty is now a pleasure. We asked three bookworms -- an English teacher, a book editor and a film critic - to pick some favorite reads for you.
