The approach we propose is a system-oriented methodology for knowledge acquisition, this orientation emphasizes ongoing documentation throughout each cycle and technique applied. Program-wide documentation is suggested, both for the purpose ofinternal(1)and for later verification and(2)efforts. The documentation system we propose includes a central "knowledge acquisition(3)" which is(4)to reflect knowledge acquisition plans, session nodes, and domain expert participation.

选出应填入下面一段英语中______内的正确答案。

SOX is an alternative(1)for XML. It is useful for reading and creating XML content in a(2)editor. It is then easily transformed into proper XML. SOX was created because developers can spend a great deal of time with raw XML. For many of us, the popular XML(3)have not reached a point where their tree views, tables and forms can completely substitute for the underlying(4)language. This is not surprising when one considers that developers still use a text view, albeit enhanced, for editing other languages such as Java. SOX uses(5)to represent the structure of an XML document, which eliminates the need for closing tags and a number of quoting devices. The result is surprisingly clear.

从供选择的答案中选出应填入下面一段英文中______内的正确答案。 In computers, encoding is the process o

从供选择的答案中选出应填入下面一段英文中______内的正确答案。

In computers, encoding is the process of putting a sequence of(1)characters (letters, numbers, punctuation, and certain symbols) into a specialized(2)format for efficient transmission or storage.(3)Decoding is the opposite process—the conversion of an encoded format back into the original(4)sequence of characters. Encoding and decoding are used in data communications, networking, and storage. The term is especially(5)applicable to radio (wireless) communications systems.

The terms encoding and decoding are often used in reference to the(6)processes of analog-to-digital conversion and digital-to-analog conversion. In this sense, these(7)terms can apply to any form of data, including text, images, audio, video,(8)multimedia, computer programs, or signals in sensors, telernetry, and control systems. Encoding should not be confused with encryption, a process in which data is deliberately altered so as to(9)concealits content. Encryption can be done without changing the particular(10)code that the content is in, and encoding can be done without deliberately concealing the content.

供选择的答案:

1.terms 2.Decoding 3.processes 4.format 5.code

6.multimedia 7.applicable 8.conceal 9.equence 10.characters
