An expert system is a software that (41) specialist knowledge-about a particular domain of (42) and is capable of making (43) decisions with in that domain. Although expert systems typically focus on a very narrow domain, they have achieved dramatic success with (44) problems, This has excited wide spread interest outside the research laboratories from which they emerged.
Expert systems have given rise to a set of "knowledge engineering" methods constituting a new approach to design of high performance software system. This new approach represents an (45) change with revolutionary consequences.
A．develops
B．directory
C．effect
D．encapsulates
E．evolutionary
F．experienced
G．expertise
H．intelligent
I．real-life
J．real-time
参考答案：E
解析：
[分析]： 专家系统是一种封装的、关于特定领域专家知识的软件，在这个特定的领域中，这种软件可以做出正确的决定。尽管专家系统通常只涉及较窄的领域，但它们已经在一些现实生活的问题中取得了显著成功。这种成功激发了广大的、各领域的实验研究人员的兴趣。
专家系统提出了一系列“知识工程”方法，它提供了一种设计高性能软件系统的新方法。这种方法代表了一种将带来革命性影响的变革。
