     Time spent in a bookstore can be most enjoyable, whether you are a book-lover or merely you

are there to buy as a present. You may even have entered the shop just to find a 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(不可抗拒的), 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 spend 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 book-shop. There are not many places where it is possible to do this. A music shop is very much like a bookshop.

You can wander around such places to your heart's content. If it is a good shop, no assistant will

approach you with inevitable greetings "Can I help you, sir?" You needn't buy anything you don't want.

In a bookshop an assistant should remain in the background until you have finished browsing(浏览).

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 bok. 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

carrying a copy of the latest best-selling novel and perhaps a book about brass-rubbing-something

that had only slightly interested you up until then. 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.
