正确答案: A

estimating

题目：The process of（）schedule activity durations uses information on schedule activityscope of work, required resource types, estimated resource quantities, and resource calendarswith resource availabilities.

解析：该题的关键词为"schedule activity durations"，其语句结构为"The process（主语）of（）schedule activity durations uses（谓语）information"，语句的含义为"(?)进度活动持续时间的过程使用信息"，结合选项，此处应该选择动词，所以观察对进度活动持续时间采取什么行为会应用到各种信息（information on schedule activity scope of work, required resource types, estimated resource quantities, and resource calendars with resource availabilities)，只有在估算进度活动持续时间时才会使用这些信息得到活动的工期，其他选项容易排除，因而选项A符合题意要求。

[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。
