BGood evening, ladies and gentlemen, I’m Roy , and this is my show. This is a television show for all families, and I know you’ll enjoy it.Let’s start with a story. Once there was a proud pig on a farm . He thought he was the most important of all the animals on the farm. But it was not enough that he himself thought this: he had to be sure that other animals thought it, too. So he went up to a chicken and asked, “ Who is the most important animal on the farm?” The chicken answered, “ You are, Mr. Pig .” Then he asked a dog, and he got the same reply.Next, he asked a cow. When the cow seemed uncertained of the right answer, the pig looked angry, and showed his teeth, “ Oh, you are, of course, Mr. Pig.” said the cow. “ Of course, ” the pig said, “ there is no doubt about it. ”At last the pig asked a big horse the same question. The horse lifted one foot, rolled the pig over and placed his foot on the pig’s head. “ I think you know the answer now. ” said the horse.61.

Software entities are more complex for their size than perhaps any other human construct,because no two parts are alike（at least above the statement level）.If they are,we make the two similar parts into one,a（1）,open or closed.In this respect software systems differ profoundly from computers,buildings,or automobiles,where repeated elements abound.Digital computers are themselves more complex than most things people build;they have very large numbers of states.This makes conceiving,describing,and testing them hard.Software systems have orders of magnitude more（2）than computers do.Likewise,a scaling-up of a software entity is not merely a repetition of the same elements in larger size;it is necessarily an increase in the number of different elements.In most cases,the elements interact with each other in some（3）fashion,and the complexity of the whole increases much more than linearly.The complexity of software is a（an）（4）property,not an accidental one.Hence descriptions of a software entity that abstract away its complexity often abstract away its essence.Mathematics and the physical sciences made great strides for three centuries by constructing simplified models of complex phenomena,deriving,properties from the models,and verifying those properties experimentally.This worked because the complexities（5）in the models were not the essential properties of the phenomena.It does not work when the complexities are the essence.Many of the classical problems of developing software products derive from this essential complexity and its nonlinear increases with size.Not only technical problems but management problems as well come from the complexity.4、____A.surfaceB.outsideC.exteriorD.essential
