软件设计中划分模块的一个准则是 (22) 。两个模块之间的耦合方式中， (23) 耦合的耦合度最高， (24) 耦合的耦合度最低。一个模块内部的聚敛种类中， (25) 内聚的内聚度最高， (26) 内聚的内聚度最低。

A．偶然 且逻辑
C．功能
D．过程

答案

参考答案：A

解析：(22)～(26)模块独立性，是指软件系统中每个模块只涉及软件要求的具体的子功能，而和软件系统中其他的模块的接口是简单的。一般采用两个准则度量模块独立性，即模块间耦合和模块内聚：耦合反映模块之间的互相连接的紧密程度，耦合度从低到高依次为非直接耦合、数据耦合、标记耦合、控制耦合、外部耦合、公共耦合和内容耦合；内聚反映模块功能强度(一个模块内部各个元素彼此结合的紧密程度)，从低到高依次为偶然内聚、逻辑内聚、瞬时内聚、过程内聚、通信内聚、顺序内聚和功能内聚。模块独立性比较强的应是高内聚低耦合的模块。

A good translator is by definition bilingual. The opposite is not ______(1) true, however. A born and bred bilingual will still need two__________(2) to become a translator: first, the skills and experience necessary for__________(3); second, knowledge of the field in which he or she will__________(4). The skills and experience for translation include the ability to write ______(5) in the target language, the ability to read and understand the_________(6) language material thoroughly, and the ability to work with the latest__________(7) and communication hardware and software.Does a born and bred bilingual__________(8) a better translator than someone who learned language B later in__________(9) There is no definite answer, but the following issues are important.__________(10), a born and bred bilingual often suffers from not truly knowing __________(11) language well enough to translate, with some even suffering from what __________(12) known as a lingualism, a state in which a person lacks_________(13) full, fluent command of any language. Second, born and bred bilinguals__________(14) don’’t know the culture of the target language well enough to_________(15) top-quality translations, or cannot recognize what aspects of the source language__________(16) its culture need to be treated with particular care, as they_________(17) in a sense too close to the language. And last, they often_________(18) the analytical linguistic skills to work through a sticky text.On_________(19) other hand, the acquired bilingual may not have the same in-depth _________(20) of colloquialisms, slang, and dialect that the born bilingual has. Also, the acquired bilingual will not be able to translate as readily in both directions (from B to language A and A to language B). Finally, born bilinguals often have a greater appreciation of the subtleties and nuances of both their languages than someone who learns their B language later in life can ever hope to have.
