第1题：

DOM is a platform. and language-(66)AP1 that allows programs and scripts to dynamically access and update the content, structure and style. of WWW documents(currently, definitions for HTML and XML documents are part of the specification). The document can be further processed and the results of that processing can be incorporated back into the presented(67). DOM is a(68)-based API to documents, which requires the whole document to be represented in(69)while processing it. A simpler alternative to DOM is the event-based SAX, which can be used to process very large(70)documents that do not fit into the memory available for processing.

A．specific

B．neutral

C．contained

D．related

正确答案：B
解析：DOM是一种与平台和语言无关的应用程序接口(API)，它可以动态地访问程序和脚本，更新其内容、结构和WWW文档的风格(目前，HTML和XML文档是通过说明部分定义的)。文档可以进一步被处理，处理的结果可以加入到当前的页面。DOM是一种基于树的API文档，它要求在处理过程中整个文档都表示在存储器中。另外一种简单的API是基于事件的SAX，它可以用于处理很大的XML文档，由于大，所以不适合全部放在存储器中处理。

第2题：

DOM(Document Object Model)最适合应用在()。

A.内存受限时

B.只有特定的元素需要处理

C.文档很大

D.文档必须非顺序地处理

参考答案：D

第3题：

在DOM中通过元素ID号访问对象的正确方法是（）。

A.document.getElementsByName（“元素名称”）

B.document.getElementsByTagName（“标记名称”）

C.document.getElementsById（“元素id”）

D.document.getElementsById（“元素id”）

正确答案：C

第4题：

System analysis is traditionally done top-down using structured analysis based on____.Object-oriented analysis focuses on creation of models.The three types of the analysis model are__请作答此选项__.There are two substages of object-oriented analysis.____focuses on real-world things whose semantics the application captures.The object constructed in the requirement analysis shows the____of the real-world system and organizes it into workable pieces.____addresses the computer aspects of the application that are visible to users.The objects are those which can be expected to vary from time to time quite rapidly.

A.function model,class model and state model
B.class model,interaction model and state model
C.class model,interaction model and sequence model
D.function model,interaction model and state model

答案：B

解析：

传统的系统分析以功能分解为基础，利用结构化分析自顶向下完成。面向对象分析关注于模型的创建。该分析模型有三种类型：类模型、交互模型和状态模型。面向对象分析有两个子阶段。领域分析侧重于现实世界中那些语义被应用程序获取的事物。在需求分析中所构造的对象说明了现实世界系统的静态结构并将其组织为可用的片段。应用分析处理应用系统中用户可见的计算机问题。所分析的对
