[单选题]In approximating costs, the estimator considers the possible causes ofvariation of the cost estimates, including（）

正确答案 ：C

risk

解析：该题的关键词为"approximating costs、 causes ofvariation"，其语句结构为"the estimator （主语）considers（谓语）the possible causes ofvariation of the cost estimates, including（）"，含义为"估算人员考虑对成本估算可能造成影响的原因，包括什么"。估算成本考虑不确定性，而不确定性正是风险的一个基本特征，所以选择选项C。

[单选题]The project team members should also be aware of one of the fundamental tenets of modern quality management: quality is planned, designed and built in, not（）

正确答案 ：B

inspectedin

解析：该题的关键词为"planned、designed、built in"，其关键的语句结构为"quality（主语）is planned，designed and built in，not（）（谓语）"，含义为"质量是通过计划、设计、制造而得到的，不是什么"，易知此处应该选择与计划、设计、制造方式相反的观点，结合四个选项，CD首先可以排除，因为从形式上应该选择过去分词形式。选项A的含义与built in相似，排除法可以得到选项B，其实这句话是质量管理中一个非常著名的说法，原文可译为：项目组成员应该知道现代质量管理的一个基本原则，即质量是通过计划、设计和制造得到的，而不是通过事后检查得到。

[单选题]Project work packages are typically decomposed into smaller components called activities to provide a basis for（）scheduling, executing, and monitoring and controllingthe proj ect work.

正确答案 ：B

estimating

解析：该题的关键词为"scheduling、executing、monitoring、controlling"，其语句结构为''Project work packages（主语）are typically decomposed into（谓语）smaller components"，含义为"项目工作包通常被分解为更小的活动"，分析后得知空白处的选项应该和上述的关键词为并列的词语，且顺序排列在其他的关键词之前，因而只能选择选项B，因为只有首先进行项目估算，才能制定项目进度，然后才能执行和监控，其他选项不符合题意。

[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.

正确答案 ：

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。
