第1题：
Asystem's architecture is a representation of a system in which there is amapping of（71）onto hardware and softwarecomponents, a mapping of the（72）onto thehardware architecture. and a concern for the human interaction with thesecomponents. That is, system architecture is concerned with a total system, includinghardware. software, and humans.
Softwarearchitectural structures can be divided into three major categories, dependingon the broad nature of the elements they show.1）（73）embodydecisions as a set of code or data units that have to be constructed orprocured.2）（74）embody decisions as to how the systemis to be structured as set of elements that have runtime behavior. andinteractions.3）（75）embody decisions as to how thesystem will relate to nonsoftware structures in its
environment(suchas CPUs, file systems, networks, development teams, etc.).

系统架构是一个系统的一种表示，包含了功能到软硬件构件的映射、软件架构到硬件架构的映射以及对于这些组件人机交互的关注。也就是说，系统架构关注于整个系统，包括硬件、软件和使用者。软件架构结构根据其所展示元素的广义性质，可以被分为三个主要类别。1）模块结构将决策体现为一组需要被构建或采购的代码或数据单元。2）构件连接器结构将决策体现为系统如何被结构化为一组具有运行时行为和交互的元素。3）分配结构将决策体现为系统如何在其环境中关联到非软件结构，如CPU、文件系统、网络、开发团队等。 -

● For nearly ten years, the Unified Modeling Language (UML) has been the industry standard for visualizing, specifying, constructing, and documenting the （71）of a software-intensive system. As the （72）standard modeling language, the UML facilitates communication and reduces confusion among project （73）The recent standardization of UML 2.0 has further extended the language's scope and viability. Its inherent expressiveness allows users to（74)everything from enterprise information systems and distributed Web-based applications to real-time embedded systems. The UML is not limited to modeling software. In fact, it is expressive enough to model （75） systems,such as workflow in the legal system, the structure and behavior. of a patient healthcare system, software engineering in aircraft combat systems, and the design of hardware. To understand the UML, you need to form. a conceptual model of the language, and this requires learning three major elements: the UML's basic building blocks, the rules that dictate how those building blocks may be put together, and some common mechanisms that apply throughout the UML.

第4题：
At a basic level, cloud computing is simply a means of delivering IT resources as （71）.Almost all IT resources can be delivered as a cloud service: applications, compute power, storage capacity, networking,programming tools,even communication services and collaboration （72）。
Cloud computing began as large-scale Internet service providers such as Google,Amazon,and others built out their infrastructure. An architecture emerged: massively scaled, （73） distributed system resources,abstracted as virtual IT services and managed as continuously configured, pooled resources. In this architecture, the data is mostly resident on （74）“somewhere on the Intemet”and the application runs on both the "cloud servers”and the user’s browser.
Both clouds and grids are built to scale horizontally very efficiently. Both are built to
withstand failures of （75） elements or nodes. Both are charged on a per-use basis. But while grids typically process batch jobs, with a defined start and end point, cloud services can be continuous. What’s more, clouds expand the types ofresources available —— file storage, databases, and Web services —— and extend the applicability to Web and enterprise applications.
(71)
A. hardware
B. computers
C. services
D. software

本段英文简要介绍云计算的概念。云计算主要是将资源看作云服务，包括应用程序、计算能力、存储容量、网络、编程工具，以及通信和协作工具。云计算最初由一些大的Internet服务提供商构建的基础设施而起步，其架构呈现出大规模、水平分布式系统资源、抽象的IT服务、管理持续配置、资源池等特性，数据大多存储于Internet上的某个地方的服务器上，应用程序运行于云服务器和用户浏览器中。云和网格都针对有效的水平可扩展性，避免节点的单点失效对系统的影响，都按使用付费。它们的区别是：网格通常是处理一批有明确定义起点和终点的作业，而云服务是可以连续不断的。另外，云扩展了资源的类型，包括文件存储、数据库和Web服务等，也将适用性扩展到Web和企业应用 -
第5题：
Cloud computing is a phrase used to describe a variety of computing concepts that involve a large number of computers ___71___ through a real-time communication network such as the Internet. In science, cloud computing is a ___72___ for distributed computing over a network, and means the ___73___ to run a program or application on many connected computers at the same time.
The architecture of a cloud is developed at three layers: infrastructure, platform, and application. The infrastucture layer is built with virtualized computestorageand network resources. The platform lay-er is for general-purpose and repeated usage of the collection of software resources. The application layer is formed with a collection of all needed software modules for SaaS applications. The infrastucture layer serves as the ___74___ for building the platform layer of the cloud. In turn, the platform layer is founda-tion for implementing the __请作答此空___ layer for SaaS application.A.resource
B.service
C.application
D.software答案：C解析：云计算是一个用来描述各种计算概念的一个短语，计算概念涉及大量计算机通过实时通信的网络，如Internet，连接在一起。在科学研究中，云计算是分布式网络计算的同义词，意味着有能力同时在多台互连的计算机上运行一个程序或应用。
云的结构分为3层：基础设施、平台和应用。基础实施层由虚拟计算机存储和网络资源构成；平台层是具有通用性和复用性的软件资源的集合；应用层是云上针对SaaS应用的所有应用软件的集合。基础设施层时建立平台层的硬件基础；相应地，平台层是执行应用层SaaS应用的基础。
