现在千军万马过独木桥的报考公务员，作为大学毕业生，你怎么看？

某分部工程的网络计划如图7-1所示，计算工期为44天。A、D、I三项工作使用一台机械顺序施工。
[问题]
1．按A→D→I顺序组织施工，则网络计划变为图7-2。
(1)计算工期是多少天？
(2)机械在现场的使用和闲置时间各是多少天？
2．如按D→A→I顺序组织施工，则网络计划变为图7-3。
(1)计算工期是多少天？

3．试比较以上两个方案的优缺点。
4．监理工程师如批准按D→A→I顺序施工，施工中由于业主原因，B项工作时间被拖延5天，因此承包商提出要求延长5天工期。
网络计划如图7-4所示。
你认为工期延长几天合理？为什么？签发机械闲置(赔偿)时间几天合理？为什么？
