问答题 案例分析题

某高校新建一栋办公楼和一栋实验楼,均为现浇钢筋混凝土框架结构。办公楼地下1层、地上19层,建筑檐高82m;实验楼6层,建筑檐高22m。建设单位与某施工总承包单位签订了施工总承包合同。合同约定:(1)电梯安装工程由建设单位指定分包;(2)保温工程的保修期限为10年。施工过程中,发生了下列事件:事件一:总承包单位上报的施工组织设计中,办公楼采用1台塔吊、1台外用电梯;在七层楼面设置有自制卸料平台;外架采用悬挑脚手架,从地上2层开始分五次到顶。实验楼采用1台物料提升机;外架采用落地式钢管脚手架。监理工程师按照《危险性较大的分部分项工程安全管理办法》(建质[2009]87号)的规定,要求总承包单位单独编制与之相关的专项施工方案并上报。事件=:办公楼外用施工电梯与各楼层连接处搭设卸料通道,与相应的楼层接通后,仅在通道两侧设置了临边安全防护设施。地面进料口处仅设置安全防护门,且在相应位置挂设了安全警示标志牌。监理工程师认为安全设施不齐全,要求整改。事件三:办公楼电梯安装工程早于装饰装修工程施工完,提前由总监理工程师组织验收,总承包单位未参加。验收后电梯安装单位将电梯工程有关资料移交给建设单位。整体工程完成时,电梯安装单位已撤场。由建设单位组织,监理、设计、总承包单位参与进行了单位工程质量验收。事件四:总承包单位在提交竣工验收报告的同时,还提交了《工程质量保修书》,其中保温工程保修期按《民用建筑节能条例》的规定承诺保修5年。建设单位以《工程质量保修书》不合格为由拒绝接收。

指出事件三中错误之处,并分别给出正确做法。

Almost everyone is afraid of something --- snakes, heights, public speaking and so on.

It is normal and can even be helpful to experience fear sometimes. In dangerous situations, fear can keep our bodies alert (警醒的) so that we can act quickly to protect ourselves.

But for some people, fear develops into a “phobia”, which is a strong and unreasonable fear of something. For example, the majority of us feel a little scared when looking down from a tall building. But people with height phobia may have trouble breathing, feel dizzy or turn down a great job just because the company is on the 20th floor.

Phobias can prevent you from living a normal life. “People with spider phobia would stay out of their home or dormitory room for days if they thought a spider was present,” Katherina Hauner, a researcher at Northwestern University, US, told ABC news. This is why scientists have been trying to find a cure for this disease.

Since fear comes from experience --- from what we are told, what we see others experience and what happens to us --- some scientists think if they can “rewrite” these unpleasant memories, they might be able to help people overcome their phobias.

In a study by Hauner and other scientists, participants with spider phobia were asked to first touch a spider with a paintbrush. Seeing that it was not actually dangerous, they then tried touching it while wearing a glove. Finally, they could hold it with their hands.

Certain medicine has also been found to be helpful. Back in 2010, researchers at the University of Hiroshima, Japan, injected (注射) a special medicine into a fish --- who was afraid of light --- to turn off the fear center in its brain. From then on, the fish no longer feared light.

While the search for solutions to phobias is making great progress, it’s an open question whether getting rid of fear is good. Some people want to use these methods to make soldiers fight harder in wars by taking away their sense of fear. Dave Smithson of the charity Anxiety UK thinks that’s a bad idea. “It’s fear that prevents us from doing crazy things,” he says. “There’s a name for people who don’t have fear of consequences: psychopaths (精神变态者).
