     Some people think that as more and more people have televisions in their homes, fewer and fewer people

will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the

information in a few minutes and with pictures? Why read the life story of a famous man, when a short

television program can tell you all that you want to know?

     Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of

every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment.

Although some books with hard covers are expensive, many books are printed today as paperbooks (平装本),

which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening

at the cinema or the theater, and you can keep a book for ever and read it many times.

     Books are a wonderful provider of knowledge and pleasure and some types of books should be in every

home. Every home should have a good dictionary. A good encyclopedia (百科全书), though expensive, is

useful, too, because you can find information on any subject. Besides, you can have such books as history

books, science textbook, cookbooks, and collections of stories and poems. Then from time to time you can

take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.
