正确答案: A

costaggregation

题目：The（）technique involves using project characteristics in a mathematical model to predict total project cost. Models can be simple or complex.

解析：可以注意到该题的关键词为"mathematical model"和"predict total project cost"，再划分语句结构"The（）technique(主语)involves(谓语)using project characteristics in a mathematical model to predict total project cost"，易理解语句含义为"什么技术使用数学模型预测项目的总成本"。观察四个选项，ABD也可能应用数学模型，也可能只是简单的数字规定，但选项C 一定会应用数学模型，所以应该选择parametric estimating。

[单选题]Organizations perform work to achieve a set of objectives. Generally, work can be categorized as either projects or operations, although the two sometimes are（）

overlap

解析：该题的关键词为"categorizedprojects or operations"，其语句结构为"Generally,work（主语）can be categorized（谓语）as either projects or operations, althoughthe two（主语）sometimes are（）（谓语）"，含义为"通常，工作可以分类为项目型和运作型工作，尽管两者有时(?)"，因两者既有相同之处，也有不同的地方，所以选择C。选项D对应的单词"dissever"疑为拼写有误。

[单选题]The receiving activities conduct analyses of the requirements with the requirements provider to ensure that a compatible, shared understanding is reached on the meaning of the requirements. The result ofthis analysis and dialog is an（）set of requirements.

agreed-to

解析：该题的关键词为"compatible, shared understanding"，其主要的语句结构为"The result of this analysis and dialog（主语）is（谓语）an____set of requirements（表语）"，含义为"分析和讨论对应的结果为一组什么的需求"，根据题意，应该是达成一致的需求集，所以从选项中识别短语，判断短语的正确形式，此处应该选择agreed-t0。agree with表示同意某人，agree to表示同意某事，此处的"同意"作为形容词性质出现，所以应该使用agreed to形式，其他都不对。

[单选题]In the process of communication requirement analysis, the project manager should consider the number of potential communication channels or paths as an indicator of the complexity of a project's communication. According to Metcalfe's Law, a project with 10 stakeholders has（）potential communication channels.

[单选题]Estimating schedule activity costs involves developing an (1) of the cost of theresources needed to complete each schedule activity. Cost estimating includes identifying and considering various costing alternatives. for example, in most application areas, additionalwork during a design phase is widely held to have the potential for reducing the cost of the execution phase and product operations. the cost estimating process considers whether the expected savings can offset the cost of the additional design work. cost estimates are generally expressed in units of (2) to facilitate comparisons both within and across projects.the (3) describes important information about project requirement that is considered during cost estimating.

解析：阅读试题可知，整段文章讨论的内容集中于"Costestimating"，分析问题(1)的语句结构为"estimatingscheduleactivitycosts（主语）involves（谓语）developingan(1)ofthecostoftheresources"。接下来使用排除法，如果对于"estimatingscheduleactivitycosts"的特定内容不了解，似乎哪个选项也可以，注意"thelresourcesneededtocompleteeachscheduleactivity"，既然每项活动所需的资源都需考虑，那就只能选择答案summary，summary在此处解释为"汇总"。分析问题(2)对应的语句，"costestimates（主语）aregenerallyexpressed（谓语）inunitsof(2)tofacilitatecomparisonsbothwithinandacrossprojects"，结合选项，此句的含义为"成本估算（结果）通常以作为单位"，故而只能选择C，Currency的含义为"货币"、"通货"，考生即使不熟悉这个单词，也能轻易排除其他三个选项。问题(3)对应的语句，"the(3)（主语）describes（谓语）importantinformationaboutprojectrequirementthatisconsideredduringcostestimating"，所以该句的含义即"描述了成本估算时应考虑的项目需求"。显而易见，选项C和D容易排除，但选择"Projectscopestatement"还是"Scopeofwork"？Scopeofwork（工作说明书）是合同中的附件，用于说明合同的工作范围（此时项目尚未建立），因而选择选项A。

[单选题]Many of the activities performed during the preliminary investigation are still being conducted in(1),but in much greater depth than before. During this phase, the analyst must become fully aware of the (2) and must develop enough knowledge about the (3)and the existing systems to enable an effective solution to be proposed and implemented. Besides the(4)for process and data of current system, the deliverable from this phase also includes the(5)for the proposed system.
