1．Increasing resources on the critical path activities may not always shorten the length of the project because:
A．No activities are time-dependent or resource-dependent
B．Activities are always scheduled with optimal number of resources
C．The Project Manager always selects original resources with the highest skill levels
D．Adding more resources may create additional work and produce inefficiencies
在关键路线上增加资源不会总是缩短项目的时间长度,这是因为:
A．没有活动是依赖时间或依赖资源的
B．总是以最佳的资源数量来安排活动
C．项目经理总选择具有最高技能水平的初始资源
D．增加更多的资源可能产生额外的工作并且导致效率低

2．Among the common types of scheduling techniques, task relationships are best illustrated using:
A．Networks
B．Gantt charts
C．Milestone charts
D．Work Breakdown structure
在计划安排技术的普通类型中用下列哪一项能最好地说明工作任务关系:
A．网络
B．甘特Gantt图
C．里程碑图
D．工作分解结构

3．Bar charts are most appropriate for:
A．Comparing actual to planned performance for each activity
B．Showing slack time
C．Showing critical path dependencies
D．Showing which activities can be rearranged in parallel
柱形图最适合于:
A．对每项活动比较实际的与计划的绩效
B．表示松弛时间
C．表示关键路线的依赖关系
D．表示哪些活动能被重新并行安排

4．Using the figure below, activity D has a latest start time of weeks and a
latest finish time of weeks．
A．2, 10
B．4, 12
C．6, 14
D．7, 15
利用下图数字计算, 活动 D 最迟开始时间是周和最迟完成时间是周
A．2,10
B．4,12
C．6,14
D．7,15

5．Which of the following does not represent the critical path?
A．Has a high degree of risk
B．Will elongate the project if the activities on this path take longer than anticipated
C．Must remain on schedule
D．Has the largest number of activities of any path
下列哪一项不代表关键路线?
A．有高度风险
B．如果这条路线上的活动要比所预期的花更长时间,项目时间将延长
C．必须保持按进度

D．任何有最大数目活动的路线
6．Networks are a result of the process and a key input to the process．
A．Activity definition, duration estimating
B．Activity sequencing, schedule development
C．Activity planning, schedule development
D．Activity sequencing, duration estimating
任务网络是过程的一个结果和是对过程的一项关键的输入
A．活动定义, 工期估计
B．活动排序,进度制定
C．活动规划,进度制定
D．活动排序, 工期估计

7．Which method shown below would normally not be used for shortening the schedule?
A．Crashing
B．Changing the scope
C．Performing activities in parallel rather than in series
D．Resource leveling
下面哪一方法通常不会被用来缩短进度?
A．赶工
B．变更范围
C．以并行方式而不是序列方式来实施进行活动
D．资源平衡

8．In a start-to-start relationship between two tasks not on the critical path, the project team determines that the start of the successor task must be delayed 3 days after the start of its predecessor．This delay is referred to as
A．Slack
B．Free float
C．Level float
D．Lag
在非关键路线上的二件工作之间的开始到开始关系中项目团队认为: 在前序工作开始之后, 后序工作的开始时间要被延迟3天这种延迟被称为
A．时差
B．自由时差
C．水平时差
D．滞后

9．In some Arrow Diagramming Method (ADM) networks, the project manager may be required to indicate logic relationships that do not consumer resources or time．These relationships are shown by using:
A．Critical path activities
B．Non-critical path activities
C．Slack time activities
D．Dummy activities
在箭线图示法(ADM) 网络中可能要求项目经理标明不消耗资源或时间的逻辑关系表
示这种关系可借助于:
A．关键路线活动
B．非关键路线活动
C．有闲时间活动
D．虚活动

10．A possible disadvantage of a bar chart is that it:
A．Lacks time-phasing
B．Cannot display more than one variable
C．Does not show activity interrelationships well on large complex projects
D．Cannot be related to manpower planning
柱形图的一个可能的缺点(劣势)是:
A．缺乏时间定位
B．不能展示出多个变量
C．在大的复杂项目上,不能很好地表示出活动之间的相互关系
D．不能与人力规划相联系
