问题 All known techniques for handling complex problems successfully seem to fall into one of the three classes: subdividing the problem(51), ignoring irrelevant detail in a safe way(52), and having an independent agent(53)the internal consistency(contextual checking). The first two provide guidelines for solving the problem, the third serves to provide early warnings. A good programming language supports all three.In subdividing problem, some of the subproblems may be similar to the(54) problem. It leads us to a(55)solution. This(55)solution is viable provided each of the subproblems is easier to solve than the original problem.

选项 A、check
B、original
C、perform
D、recursive

答案D

解析 已知的能成功地处理复杂问题的所有技术可以分为下列三类:分解问题组马成分;采取某种安全的抽象,忽略不相关的细节;设置一个独立的代理,检查内部一致性(上下文检查)。前两种方法为解决问题提供了指导方针,第三种方法用来提供早期的警告。一个好的程序设计语言必须同时支持这三种方法。在问题分解中,一些子问题可能与原来的问题类似,这使我们使用递归解法。只要每个子问题比原来的问题更易于解决,这种递归解法就是可行的。
本题的A小题的6个备选项中,除了composition(组成成分)为,其余5个单词都或多或少地与subdividing 有着相近的含义。在计算机建模过程中,一般都是通过抽象的手段来忽略一些不相关或关联很少的细节问题。本题的C、 D、E的答案是显然的。
