[单项选择] Time spent in bookshop can be most enjoyable, whether you are a book lover or merely there to buy a book as a present. Whatever the person, you can soon become totally unaware of your surroundings. You soon become engaged in some books, 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. A music shop is very like a bookshop. You can wander round such places to your heart’’s content. If it is a good shop, no assistant will approach you with the inevitable greeting: "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.
You have to be careful not to be attracted by the variety of books in
A. a best-selling novel on brass-rubbing
B. a book on ancient coins
C. a book on the subject that vaguely interests you
D. a book well illustrated and expensive
[单项选择]
Almost Human
Scientists are racing to build the world’s first thinking robot. This is not science fiction: some say they will have made it by the year 2020. Carol Packer reports.
Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (机器人) which scientists have built at the Massachusetts Institute of Technology (MIT). Kismet is different from the traditional robot because it can show human emotions. Its eyes, ears and lips move to show when it feels happy, sad or bored. Kismet is one of the first of a new generation of androids—robots that look like human beings—which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old.
The optimists (乐观主义者) say that by the year 2020 we will have created humanoids (机器人) with brains similar to those of an adult human bei
