参考答案：

● 参考解析

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。
