某工程，业主在招标文件中规定：工期T(周)不得超过80周，也不应短于60周。某施正单位决定参与该工程的投标。在基本确定了技术方案后，为提高竞争能力，对其中某技术措施拟定了3个方案进行比选。方案一的费用为C1＝100+4T；方案二的费用为 C2＝150+3T；方案二的费用为C3＝250+2T。
这种技术措施的3个比选方案对施工网络计划的关键线路均没有影响。各关键工作可压缩的时间及相应增加的费用见表6-1。
假定所有关键工作压缩后不改变关键线路。
该工程采用问题1中选用的技术措施方案时的工期为80周，造价为2653万元。为了争取中标，该施工单位投标应报工期和报价各为多少？
参考答案：
由于方案二的费用函数为：C2＝150+3T，所以对压缩1周时间增加的费用小于3万元的关键工作均可压缩，即应对关键工作C和M进行压缩，则：
自报工期：(80-2-2)周＝76周
相应的报价：[2653-(80-76)×3+2.5×2+2.0×2]万元＝2650万元
完形填空（20 分） 阅读下面短文，掌握其大意，然后从下列各题所给的A、B、C和D四个选项中，选出最佳选项。 Many people of my generation(代，一代) say that there is no hope for the future because of the way that 11 people behave today. Their first argument（论点） is that when we were young we used to look after the 12 people in our community and help them. They also say that young people today don’t 13 about anything or anyone. However, I think the reason why we looked after older people was that we had no 14 . People had to live with their 15 and grandparents because they had no money. Young people today earn more and have more 16 to live where they want. Their second argument is that in our day we didn’t expect （盼望，期待）to be given jobs -----and that young people now don’t look for jobs, but just complain（抱怨） about 17 . On the other hand, things were easier in the past and it was always easy to get a job if you had friends and contacts（关系）. It is really 18 today. In conclusion I think there is hope for the 19 . This generation, like generations before them, has new 20 as well as old problems. If they learn from our mistakes the world will be a better place in future.
