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.

参考解析
解析：软件实体规模上或许比其他任何人类创造的结构要更为复杂，因为没有两个部分是一样的（至少在语句级以上）。如果他们一样，我们便将这两个相似的部分合到一起，成为一个子程序，打开或关闭。在这一点上，软件系统与计算机、建筑或汽车经常混合使用一些重复的元件有很大区别。数字计算机本身比人类所建造的大多数事物都要复杂，他们有超级多的状态。这使得对他们进行想象、描述和测试都很困难。软件系统的状态数目更是比计算机的超出几个数量级。同理，软件实体的扩展不单是这一批元件变大一点，它必将是大量不同元件都有增加。在大多数情况下，构件以非线性的方式相互作用，而整体的复杂性远超线性增加。软件的复杂的特点具有必然性，并非偶然。因此，对于软件实体的描述，剥离了它的复杂性往往就等于剥离了它的本质。过去这三个世纪，通过对复杂的现象构建出简化模型，从模型的属性再倒推，并通过实验验证这些属性，数学和物理科学取得了长足的进步。这之所以行之有效，是因为模型中忽略掉的复杂特性并不是现象中重要的本质属性。而当这些复杂性很重要时，这种方法就会失效。

Animals other than humans have not developed communications comparable to human language. But is it possible that other animals have the capacity to learn a language if they are adequately taught? Obviously, this is a fascination notion. The idea of communicating directly with another species has long been a part of human folklore and children’s fantasies. But on a scientific level, the question of whether animals can learn a language is important primarily because it relates to the controversy()between the cognitive and the learning approaches to language. If language is dependent on and is actually an outgrowth of the intellectual structure of the human mind, there is the strong supposition that only humans are capable of using language. Therefore, Noam Chomsky and other psycholinguists have argued that only humans can learn a language, while most behaviorists feel that with sufficient patience it should be possible to teach an animal some sort of language. Although the two schools of thought clearly differ on this point, it is not really a crucial test of the two theories. If a chimpanzee can master a simple language all it would mean is that the chimp’s intellectual capacity and brain structure are more similar to ours than we thought. It would not necessarily imply that our intellectual structure is unimportant in our own mastery of language. Thus, teaching an animal language is an impressive demonstration of the power of learning techniques, but it is not evidence that language is developed entirely through learning.On the other hand, the question of whether other animals can learn a language is fascination in its own right, aside from its value as a test of the two theories of language development. Accordingly, whatever one’s position on the theoretical dispute, we must consider training an animal to use language a dramatic accomplishment.36.Which of the following statements is the view of psycholinguists?A. The cognitive view of language learning says that only human beings can learn language because it is an outgrowth of the structure of the human mind.B. Other animals simply could master a language.C. The animals intellectual capacity is much better than human beings.D. Language is developed by learning.37.The behaviorists’ view is that __________.A. language is actually an outgrowth of intellectual structure of the animal’s mindB. animals have not developed communications systemC. given enough patience, a man should be able to teach an animal some sort of languageD. only human beings can learn language38.That an animal can master a simple language means that __________.A. human’s intellectual structure is not importantB. animals’ intellectual capacity and brain structure are more similar to the humans’C. the learning techniques are much more importantD. language is developed completely by learning39.The main idea of paragraph two is ___________.A. teaching a chimp language is not crucial test of the two theoriesB. their brain structure is not similar to humanC. using various methods to let the chimp master a languageD. training a nonhuman to use language is an amazing accomplishment40.The best title for this passage would be _________.A. Animals’ languageB. Human’s languageC. Teaching Animals’ LanguageD. Can Other Animals Acquire Language?

Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to protnote social change by opening more areas of life to decision.
In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed.
Within a society, social changes is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.
Furthermore, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with sharp difference. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities,because of the sharp difference in appearance between them and their white counterparts.
The passage is mainly discussing__________.A.certain factors that determine the ease with which social changes occur
B.certain factors that promote social change
C.the necessity of social change
D.two different societies

What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.
Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.

Software entities are more complex for
their size than perhaps any other human construct, because no two parts are
