施工期间,由于建设单位原因使H工作的开始时间比计划的开始时间推迟1个月,并由于H工作工程量的增加使该工作持续时间延长了1个月。
问题:

请按施工进度计划编制资金使用计划(即计算每月和累计拟完工程计划投资),并简要写出其步骤。计算结果填入表3-8中。

答案

参考答案:将各工作计划工程量与单价相乘后,除以该工作持续时间,得到各工作每月拟完工程计划投资额;再将时标网络计划中各工作分别按月纵向汇总,得到每月拟完工程计划投资额;然后逐月累加,得到各月累计拟完工程计划投资额。

Many American youngsters earn their own allowance(零花钱)by doing temporary jobs for their neighbors. Babysitting is one of the common of these jobs. Most couples do not have maids or relatives living with them, and they need to have someone watch the children if they want to go out.

Another way is by mowing lawn in summer and clearing snow from sidewalks and driveways in winter. Many people mow their own lawns,but often people prefer to give the job to a neighbor’s child. In winter, snow clearing from streets and highways is the government’s responsibility. Homeowners or tenants, however, must clear sidewalks and driveways. Since clearing snow is very tiring, many people prefer to hire teenagers for this job rather than do it themselves.

Besides, many American teenagers usually work two to three hours after school and all day on Saturday or Sunday at the local supermarket. They work as cashiers or stockroom clerks. Or they help customers carry things to their cars. Other favorite jobs are waiting on tables in restaurants or working part-time at stores or gas stations.

By earning their own allowance,teenagers acquire a feeling of independence and a sense of responsibility which prepares them for a productive life in society.
