I hear many parents saying that their teenage children are rebellion(反叛的). I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they degree with their parents. Instead of striking out bravely on their own, most of them are trying to seize at one another’s hands for safety.

They say they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow reason for thinking or acting in thus-and-such a way is that the crowd is doing it. They have come out of their cocoon(蚕茧) -----into a larger cocoon.

It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly opened up a teenage market. These days every teenager can learn from newspapers and TV what a teenager should have and be. And many of today’s parents have come to award(奖励) high narks for the popularity of their children. All this adds up to great difficulty for the teenager who wants to find his or her own path.

But the difficulty is worth getting over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don’t care to share at once with your classmates. Well, go to it. Find yourself. Be yourself. Popularity will come-----with the people who respect you for who you are. That’s the only kind of popularity that really counts.

某市政工程分为四个施工标段。某监理单位承担了该工程施工阶段的监理任务,一、二标段工程先行开工。项目监理机构组织形式如图2-1所示。

一、二标段工程开工半年后,三、四标段工程相继准备开工,为适应整个项目监理工作的需要,总监理工程师决定修改监理规划,调整项目监理机构组织形式,按四个标段分别设置监理组,增设投资控制部、进度控制部、质量控制部和合同管理部四个职能部门,以加强各职能部门的横向联系,使上下、左右集权与分权实现最优的结合。

总监理工程师调整了项目监理机构组织形式后,安排总监理工程师代表按新的组织形式凋配相应的监理人员,主持修改项目监理规划,审批项目监理实施细则;又安排质量控制部签发一标段工程的质量评估报告;并安排专人主持整理项目的监理文件档案资料。

总监理工程师强调该工程监理文件档案资料十分重要,要求归档时应直接移交本监理单位和城建档案管理机构保存。

指出总监理工程师调整项目监理机构组织形式后安排工作的不妥之处,并写出正确做法。
