问答题
【背景资料】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11层，建筑檐高48m；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保温工程保修期限为10年。施工过程中，发生了下列事件：事件1：总承包单位上报的施工组织设计中，办公楼采用1台塔式起重机；在7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3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E2009187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2：实验楼物料提升机安装总高度26m，采用一组缆风绳锚固。与各楼层连接处搭设卸料通道，与相应的楼层连通后，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3：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4：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。【问题】1．事件1中，总承包单位必须就哪些工程单独编制专项施工方案？2．指出事件2中错误之处，并分别给出正确做法。3．指出事件3中错误之处，并分别给出正确做法。4．事件4中，总承包单位、建设单位做法是否合理？ -
单项选择题
Aunt Charlotte's Reward My wife's Aunt Charlotte hives in Brooklyn. A tiny, soft-spoken woman of 74, she could easily pass for 60 with her relatively unlined face and undyed brown hair that is just beginning to break out in gray flecks(雀斑). Only her diminished hearing gives her age away. Her mind and her vision are sharper than those of many 40-year-olds. A shy woman, Charlotte never married. When she telephones us she says, 'It's only me.'Working at the Telephone Company In 1923, when she was 17, Charlotte went to work for the telephone company, eventually attaining the position of customer-service representative, a role she performed with pride, skill and dedication for nearly a half century. She responded with patience and courtesy to every customer, even to those whose complaints were voiced in somewhat questionable language. Charlotte, who would commit had-kin before permitting an unladylike word to slip through her lips, never displayed a hint of anger or disapproval, although she confided to us that some of her clients should have their mouths washed out with soap. The days she was out sick could be counted on her fingers; it took a transit strike to make Charlotte late.Being Forced to Retire As a reward for her dedication, the U.S. Government forced Charlotte to retire. She was given a luncheon, a subscription to a retirement magazine, free home-telephone service and a pension and sent home. Two women in their 20s replaced her. Since the government made it difficult for them to be fired no matter what their attitude or degree of competence, neither felt compelled to duplicate Charlotte's conscientiousness(自觉) or productivity, as we say today. Distress Call: Several months afterward the telephone company sent out a distress call for retired workers. Temporary help was needed in the Upper West Side of Manhattan to handle the problems arising from the minority groups in the area, many of whom either did not know English or were puzzled(困惑) by the complexities of maintaining telephone service—problems the new employees displayed no interest in solving. Giving up her social-security checks, Charlotte set off each day to a part of the city considered dangerous for the young and fit, let alone a woman of Charlotte's age. Before long she had added an extensive Spanish vocabulary to her store of black English and was being presented with gifts by her clients. Unable to change old habits, she arrived early, stayed late and quickly worked herself out a job.City's Whack The government was not finished with Charlotte. Now it was the city's mm to take a whack(重击) at her. It moved welfare families by the score into her neighborhood, many into her building, which was like moving the fox into the hen yard. For many of these families consist of a mother and unsupervised children-children who often stand 6 feet tall and carry knifes or worse. Soon mailboxes were found ripped open, social-security checks stolen. The once neat hallways are now filled with beer cans, soft-drink and liquor bottles and the smell of marijuana(大麻). Groups of youths, radios blaring(奏鸣), gathered on the front steps late into the night, making obscene remarks and giggling as people pass. There are purse snatchings and muggings(偷窃) in the once quiet neighborhood. An elderly couple were found tied to their bed, beaten and robbed. Charlotte has stopped going out at night. When she ventured out during the day she conceals cash in various places on her person, leaving a carefully calculated amount in her purse to comfort an attacker. Visiting Charlotte requires driving past miles of burnt out apartment buildings; rims are set either by landlords for the insurance or by welfare tenants for the hardship money.(Everyone has been given an equal opportunity to profit by the system.) Although Charlotte remains outwardly cheerful, she knows she will have to do something soon. But what?&A．YB．NC．NG
