单项选择题

阅读下面的文字,完成下列4题。

什么是信息呢在我们的日常生活中,信息是指具有新内容、新知识的消息。比如,人们收听了一次广播,听到了一些新闻,也就是接受到一些信息。同样,人们从别人的谈,话和通信中,从电话和电视中,从阅读书报和文献资料中,从接触自然景物和周围环境中等等所获得的新消息,也都是信息。信息和消息是有区别的。人们听到的消息,它的内容可能已经是知道的,也可能是还不知道的。事先已经知道的消息不是信息,因为人们不能从中获得新内容和新知识。作为信息,必须是事先不知道它的内容的新消息,即具有“能够消除某些知识的不肯定”的性质。

信息作为科学的概念,首先是在信息论中专门研究的,而信息论又是从通信科学中产生和发展起来的。1948年,美国贝尔电话公司的申农博士,在研究信源和信道特征的基础上,发表了《通信的数学理论》的著名论文。由于这篇论文是以研究一个特定系统的传输的信息量为起点,因而被称为信息论。这篇论文是信息论诞生的重要标志。与此同时,美国数学家维纳在创立控制论时,也研究了信息问题。这样,信息就开始作为基本概念进入科学领域。

在申农看来,信息乃“两次不定性之差”。所谓“不定性”,就是人们对客观事物不了解,“不确定”。“两次不定性之差”就是指人们在获得新知识之后,改变了原有的知识状态,减少或消除了原先的“不定性”。

申农的信息概念是他的通信理论中的一个重要概念。从申农的通信系统图示可以看出,通信就是两个系统之间传递信息,即从信息源发出消息(信息),消息通过编码,变换成信号,信号在信道中传输,在信道中传输信号的同时还会受到种种噪音的干扰,通过信道传输后的信号再通过译码变换成消息,信宿(接受者)就可以从中获取信息。这种从通信系统中提出的信息概念,被称为狭义的信息概念。

本文说明的主旨是()。

A.信息和信息概念

B.信息和信息论

C.信息和通信科学

D.信息论和控制论

An “apple polisher” is one who gives gifts to win friendship or special treatment. It is not exactly a bribe(贿赂),but is close to it.

All sorts of people are apple polishers, including politicians and people in high offices ── just about everybody. Oliver Cromwell, the great English leader, offered many gifts to win the support of George Fox and his party, but failed.

There are other phrases meaning the same thing as “apple-polishing” ── “soft-soaping” or “butter-up”. A gift is just one way to “soft-soap” somebody, or to “butter him up”. Another that is just as effective is flattery, giving someone high praise ── telling him how good he looks, or how well he speaks, or how talented and wise he is.

Endless are the ways of flattery. Who does not love or hear it ? Only an unusual man can resist the thrill of being told how wonderful he is. In truth, flattery is good medicine for most of us, who gets so little of it.

We need it to be more sure of ourselves. It cannot hurt unless we get carried away by it. But we just lap it up for its food value and nourishment, as a cat laps up milk, then we can still remain true to ourselves.

Sometimes, however, flattery will get you nothing from one who has had too much of it. A good example is the famous 12th century legend of King Canute of Denmark and England. The king got tired of listening to the endless sickening flattery of his courtiers(朝臣).They overpraised him to the skies, as a man of limitless power.

He decided to teach them a lesson. He took them to the seashore and sat down. Then he ordered the waves to stop coming in. The tide was too busy to listen to him. The king was satisfied. This might show his followers how weak his power was and how empty their flattery.

小题1:Which of the following activities has nothing to do with “apple-polishing” ?

A.A boy tells his girlfriend how pretty she looks

B.An employee tells his boss how good he is at management

C.A knight(骑士)is said to be of limitless power by his followers

D.A teacher praised his students for their talent and wisdom.小题2:Which of the following statement about flattery is TRUE according to the author ?

A.Too much flattery can carry us away

B.Flattery is too empty to do people any good

C.Flattery can get nothing but excessive(过度的)pride

D.Flattery is one of the ways to apple-polish people.小题3:King Canute of Denmark and England took his followers to the seashore because __________.

A.he was sick of his normal

B.he disliked being overpraised any more

C.he wanted them to realize how wise he was

D.he wanted them to see how weak he was as a king小题4:The author thinks that flattery can do good to those who _________.

A.are really excellent

B.lack confidence

C.are politicians or in high offices

D.think highly of themselves
