单选题There are several ways you can find out about the countries
and places you wish to visit. You can talk to friends who have travelled to the
places. Or you can go and see a colour film. Or you can read travel
books. It would seem that there are three kinds of
travel books. The first are those that give a personal, subjective (主观的) account
of travels which the author has actually made himself, if they are informative
and have a good index (索引), then they can be useful to you when you are planning
your travels. The second kind are those books whose purpose is to give a purely
objective (客观的)description of things to be done and seen. If a well-read,
cultured person has written such a book, then it is even more useful. It can be
sorted as a selected guide book. The third kind are those books which are called
"a guide" to some place or other. If they are good, they will, in addition to
their factual information, give an analysis or an explanation. Like the first
kind they can be inspiring and interesting. But their basic purpose is to help
the reader who wishes to plan in the most practical way.
Whatever kind of travel book you choose you must make sure that it does not
describe everything as "wonderful", "excellent" or "magical". You must also note
its date of publication because travel is a very practical affair and many
things change quickly in the twenty-first century. Finally, you should make sure
that the contents are well presented and easy to find.The date of the publication must be noticed because （）.A
the world is changing and so are the places you are going to visitB
the price of the book is always changingC
the author of the book may be differentD
the contents of the book are always the same
