梅毒性心脏病的基本病理改变是（） A.梅毒性心肌树胶样肿 B.梅毒性主动脉瘤 C.梅

A report by the Consumer Electronics Association says electronics are among the most popular gifts being bought this holiday season. 

Jim Barry is a spokesman for the Consumer Electronics Association. He says the CEA study found that electronics represent three of the top five things on its "holiday gift wish list" this year.

JIM BARRY: "Notebook computers are at the top, followed by iPads and then e-readers. IPad is a touch-screen tablet computer and that's really the big player in that category."

The computer company Apple began selling its small, touch-screen computers in April.   People use the touch-screen computers to surf the Web, write e-mails, watch movies and read books. Since the iPad's release earlier this year, several other companies have come out with their own tablet computers just in time for Christmas.

A report from the e-Marketer research group predicts that worldwide, tablet sales will reach more than eighty-one million in two thousand twelve. Still, Jim Barry says these devices are facing tough competition this year from another Christmas favorite.

JIM BARRY: "Another hot category right behind that are the e-readers. So you can read on an iPad or a touch-screen tablet, but the e-book readers are less expensive. The Kindle is the market leader there, from Amazon. But you also have the Nook from Barnes and Noble and the e-reader from Sony. And you have more and more of those e-readers coming into the market as well."

The Consumer Electronics Association report found that iPod music players are also in high demand this holiday season.  

But not all of the things on the holiday gift wish list involved electronics. Clothes, cars and motorcycles also made the list. So did family togetherness and good health. And the one thing that people wanted most?

JIM BARRY: "At the top of the list was peace and happiness."

That is also our wish for you this holiday season.

　　Decision-thinking is not unlike. It often matters not only what you think, but also what others think you think and what you think they think you think. The mental process（过程） is similar. Naturally, this card game has often been of considerable interest to people who are, by any standards, good thinkers.

　　The great mathematician John von Neumann was one of the founders of game theory. In particular, he showed that all games fall into two classes; there are what he called games of 'perfect information', games like chess where the players can't hide anything or play tricks; they don't win by chance, but by means of logic and skills. Then there are games of 'imperfect information', like poker, in which it is impossible to know in advance that one course of action is better than another.

　　One mistaken idea about business is that it can be treated as a game of perfect information. Quite the reverse, business and life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors（因素）, as best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.

49．The subject discussed in this text is _________.

　　A．the process of reaching decisions

　　B．the difference between poker and chess.

　　C．the secret of making good business plans

　　D．the value of information in winning games

50．An important factor in a game of imperfect information is ___________.

　　A．rules               B．luck         C．time               D．ideas

51．Which of the following can be used in place of "Quite the reverse"?

　　A．Quite right.                   B．True enough.

　　C．Most unlikely.                      D．Just the opposite.

52．In the writer's opinion, when making business decisions one should ___________ .

　　A．put perfect information before imperfect information

　　B．accept the existence of unknown factors

　　C．regard business as a game of chess

　　D．mix known and unknown factors
