问题 单项选择题

在划分模块时,一个模块的作用范围应该在其控制范围之内。若发现其作用范围不在其控制范围内,则______不是适当的处理方法。

A.将判定所在模块合并到父模块中,使判定处于较高层次

B.将受判定影响的模块下移到控制范围内

C.将判定上移到层次较高的位置

D.将父模块下移,使该判定处于较高层次

答案

参考答案:D

解析:本题考查软件设计的基础知识。模块的控制范围包括模块本身及其所有的从属模块。模块的作用范围是指模块一个判定的作用范围,凡是受这个判定影响的所有模块都属于这个判定的作用范围。原则上一个模块的作用范围应该在其控制范围之内,若没有,则可以将判定所在模块合并到父模块中,使判定处于较高层次;将受判定影响的模块下移到控制范围内;将判定上移到层次中较高的位置。

单项选择题

The modern university is the ideal environment for the creation and transfer of knowledge that drives national competitiveness in an increasingly global era. Its most effective form is the American adaptation of the European model, in which teaching, leaning and research are integrated into a single institution. Indeed, the American university has proved capable of almost anything, from developing advanced economic theories to creating new life forms.

Many national leaders understand that the university is the critical catalyst for America’s adaptability, economic robustness and emergence as a great power. And they are moving aggressively to catch up. The universities created by emerging economies beginning in the 1990s and through 2020 will likely play a decisive role in reshaping the global balance of economic power.

That is bad news for the United States. The past two decades of American university development have been characterized largely by self-satisfaction arising from steady progress by the top 20 or so research universities. And America as a nation has 1Seen coasting. Since 2000, the United States has lost its edge in the graduation of engineers and technologists. The country no longer dominates scientific discovery, innovation or exploration. Most important, the United States has not launched any effort to build new institutions to accommodate its increasingly diverse population of more than 300 million.

The result is that America’s university system, despite its historical pre-eminence, has ceased to grow. Furthermore, America’s university system has failed to adapt to the dramatic demographic shifts occurring as a result of social mobility and immigration.

America needs to realize that its universities face real competition from the rest of the world to attract the best and the brightest, to secure resources and to provide environments that educate and inspire. This is not to say that the best American universities are no longer the leaders in discovery and innovation. It is to say that the success of the higher-education system must be measured by more than just innovations. Its long-term performance depends on its ability to provide learning to a broad cross sections of citizens, to advance national proficiency in math and science and to create an adaptable work force, as well as to develop a national appreciation for discovery, entrepreneurship and the creative process.

In China and elsewhere, these are the goals of the new universities being built. In the United States, we need to move from a national self-confidence based on past success to one built on the knowledge that we are advancing a system of higher education that will meet our future needs. This will require that policymakers, business leaders and universities rededicate themselves to creating comprehensive learning and discovery environments; design entirely new models and methods for teaching, and then take action to implement them.

It can be inferred from the text that the most possible direction of university reform in the US is ()

A. offering more attractive scholarships

B. developing advanced economic theories

C. finding a better system for learning and researching

D.spending more money for hardware improvement
