参考答案:B

解析:分析:活动历时估算不是进行活动排序时首要考虑的问题。在估算时,要在综合考虑各种资源、人力、物力、财力的情况下,把项目中各工作分别进行时间估计,同时要做到从大局考虑,不应顾此失彼。在对各个工作进行时间估计时,可以选择项目队伍中最熟悉具体活动性质的个人或团体来完成具体估计工作。活动历时估算可采用三点估算法。(p141) 参考答案::B

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

I felt encouraged by his words and began to swim more calmly.But my clothes stuck to me like a heavy weight.I could hardly stay above the surface.

Counsel saw this.“Shall I cut them?”he asked.

With a knife he cut my clothes from top to bottom and took them of quickly while I swam for both of us.

Then I did the same for Counsel,and we continued to swim near each other.

But we were in serious trouble.The crew(船员)might not have noticed our disappearance.

And if they had,they could not return because the rudder(舵)had broken.Counsel thought of all this,and calmly made his plans.We decided to wait for the ship as long as possible,because we had no other hope of safety.I suggested that we save our strength so that both of us would not be tired out at the same time.This was how we did it:While one of us lay on his back,quite still,with arms crossed and legs stretched out(伸直),the other would swim and push him along.We changed every ten minutes or so.In this way we could swim for hours,perhaps till daylight.The crash(破裂声)of the ship and the whale(鲸)had appeared at about eleven o’clock.We had about eight hours to swim before daylight.This seemed possible,if the sea remained calm.
