[B] A harmful practice out of human weakness.
[C] Who should take the burden of looking after our old people？
[D] A cure to loneliness found in kids.
[E] Comfort typical of a multigenerational family.
[F] Benefit of extended age groups.
Until late in 20th century, most Americans spent time with people of all generations. Now baby boomers may not have much contact with old people until they're relatively old themselves.
1. ______
That's because we group people by age. We put our three-year-olds together in day-care centers, our 13-year-olds in schools and sports activities, and our 80-year-olds in senior-citizen homes. Why？ We segregate the old for many reasons: prejudice, ignorance, a lack of good alternatives. Younger people sometimes avoid the old to evade fears of aging and dying. Death is easier to bear in the abstract. It's much harder to watch someone we love fade before our eyes. Sometimes it's so hard that we stay away from the people who need us the most.
2. ______
But there are problems with this age-segregation experiment. Ten 14-year-olds grouped together will form. a Lord of the Flies culture--competitive and mean. But ten people ages two to 80 grouped together will fall into a natural age hierarchy that nurtures and teaches them all. For our own mental and social health, we need to reconnect the age groups. Fortunately, some of us have found our way to the old. And we have discovered that they often save the young.
3. ______
A reporter moved her family onto a block filled with old people. At first her children were disappointed. But the reporter baked banana bread for the neighbors and had her children deliver it and visit. Soon the children had many new friends, with whom they shared food, stories and projects. "My children have never been less lonely," the reporter said.
4. ______
The young, in turn, save the old. Once I was in a rest home when a visitor showed up with a baby. She was immediately surrounded. People who hadn't gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed comatose woke up to watch the child. Babies have an amazing power to comfort and heal.
5. ______
Grandparents are a special case. They give grandchildren a feeling of security and continuity. As my husband put it, "My grandparents gave me a deep sense that things would turn out right in the end." Grandchildren speak of attention they don't get from harried parents. "My parents were always telling me to hurry up, and my grandparents told me to slow down," one friend said. A teacher told me she can tell which kids have relationships with grandparents: they are quieter, calmer, more trusting.

A公司中标的某城市高架跨线桥工程，为15跨25m预应力简支梁结构，桥面宽22m，采用φ1200mm钻孔灌注桩基础、埋置式承台、Y型独立式立柱。工程工期210d，中标价2850万元。经过成本预测分析，项目目标成本为2600万元。其中，管理成本（间接成本）占10%。根据总体安排，组建了以二级注册建造师（市政公用工程专业）王某为项目负责人的管理班子。 施工过程中，发生如下事件： 事件一：编制目标成本时发现，投标报价清单中灌注桩单价偏高，桥面沥青混凝土面层单价偏低。 事件二：工程开工两个月后，因资金不足，贷款500万元，共支付利息30万元。 事件三：某承台开挖基坑时发现文物，按上级有关部门要求停工30d，导致总工期拖延10d，未发生直接成本损失。
【问题】 1．王某担任本工程项目负责人符合建造师管理有关规定吗？说明理由。 2．试用不平衡报价法解释事件一中A公司投标报价的做法。 3．本项目利息支出应计入哪类成本？项目目标成本中直接成本是多少？ 4．针对事件三，项目部可以提出哪些索赔要求？说明理由。
下列进行性血胸的诊断依据中，错误的是
在招标和施工过程中，发生了如下事件：
事件一：建设单位自行组织招标。招标文件规定：合格投标人为本省企业；自招标文件发出之日起15天后投标截止；招标人对投标人提出的疑问分别以书面形式回复给相应提出疑问的投标人。建设行政主管部门评审招标文件时，认为个别条款不符合相关规定，要求整改后再进行招标。
事件二：合同约定主要材料按占总造价比重55%计，预付备料款在起扣点之后的五次月度支付中扣回。
事件三：基坑施工时正值雨季，连续降雨致停工6天，造成人员窝工损失2.2万元。一周后出现了罕见特大暴雨，造成停工2天，人员窝工损失1.4万元。针对上述情况，施工单位分别向监理单位上报了这四项索赔申请。
事件四：某分项工程由于设计变更导致该分项工程量变化幅度达20%，合同专用条款未对变更价款进行约定。施工单位按变更指令施工，在施工结束后的下一月上报支付申请的同时，还上报了该设计变更的变更价款申请，监理工程师不批准变更价款。
事件五：种植屋面隐蔽工程通过监理工程师验收后开始覆土施工，建设单位对隐蔽工程质量提出异议，要求复验，施工单位不予同意。经总监理工程师协调后三方现场复验，经检验质量满足要求。施工单位要求补偿由此增加的费用，建设单位予以拒绝。
事件六：合同中约定，根据人工费和四项主要材料的价格指数对总造价按调值公式法进行调整。各调值因素的比重、基准和现行价格指数如下表：
