[单项选择]Passage 3
| Time spent in a bookshop can be most
enjoyable, whether you are book-lover or merely you are there to buy a book as a
present. You may even have entered the shop just to find shelter from a sudden
shower. Whatever the reason, you can soon become totally unaware of your
surroundings. The desire to pick up a book with an attractive dust-jacket is
irresistible, although this method of selection ought not to be followed, as you
might end up with a rather dull book. You soon become engrossed in some book or
other, and usually it is only much later that you realize you have spent far too
much time there and must dash off to keep some forgotten appointment-without
buying a book, of course. This opportunity to escape the
realities of everyday life is, I think, the main attraction of a bookshop.
There are not many places where it is possible to do this. A music shop is
very much like a bookshop. You can wander about these places to your heart’s
content. If it is a good shop, no assistant approach you with inevitable
greeting: "Can I help you" you needn’t buy anything you don’t want. In a
bookshop an assistant should remain in the background until you have finished
browsing. Then, and only then, are his services necessary. Of course, you may
want to find out where a particular section is, but when he has led you there,
the assistant should retire carefully and look as if he is not interested in
selling a single book. You have to be careful not to be
attracted by the variety of books in a bookshop. It is very easy to enter the
shop looking for a book on ancient coins and to come out with a copy of the
latest best-selling novel and perhaps a book about brass-rubbing-something that
had vaguely interested you up until then. This volume on the subject, however,
happened to be so well illustrated and the part of the text you proved so
interesting that you had to but it. This sort of thing can be very dangerous.
Apart from running up a huge account, you can waste a great deal of time
wandering from section to section. |
You may spend too much time in a bookshop because ______.
A. the dust-jackets of some books are very attractive
B. you start reading one of the books
C. it keeps raining outside
D. you have to make sure you don’t buy a dull book as a present
