问题 单项选择题

At the beginning of the twentieth century, North American society held, as an ideal, the Nuclear Family. This presumably perfect residential, social, and economic unit consisted of an adult male, an adult female and their minor children. This structure was thought to be stable and long lasting.
However, a few decades later, the structure of that ideal family was being altered radically even while it was being touted as the structure to be aimed for. Popular magazines bemoaned the loss of the Nuclear Family and its replacement with inferior forms.
There are a number of factors that are acting in concert to apply pressure on the Nuclear Family and generate a variety of new structures. Some of these are:
The definition of marriage has changed somewhat in that few people now consider it to last "until death do us part." The concept of monogamy (the marriage of one man and one woman) has been modified to a form now referred to as serial monogamy (the marriage of one man and one woman at a time). This reflects the increasing equality of women and men in terms of economic advantage and the recognition that many women no longer depend on men for their survival. Women are acquiring independence and have become empowered to make their own choices. With this independence, the need to form a relationship with a man becomes less important. This change embodies the concept that the marriage is temporary and can be terminated by either partner at any time. Associated with this, of course, is the relaxation of the divorce laws and the significant reduction of the shame that had one time been attached to divorce.
The economy of North America has resulted in a two-tier system of a few rich who control most of the resources and a large portion of the population who control almost none of the resources. Because of this, many couples are forced to have both partners with full-time jobs outside the home. There are unintended byproducts of the need for a double income. The most important of these is the replacement of a mother-oriented socialization of children to a "stranger-oriented" socialization system reflected in the growth of the childcare industry. Also, either partner is financially able to end the marriage without significant hardship.
The combination of these changes will in the coming decades have a profound effect on the structure of the family of North America. As a result, the family will be a fluid, constantly changing structure with variable household arrangements as the norm.

What is the major factor that has raised the divorce rate in North America

A.The increasing equality of women.

B.Relaxation of the divorce laws.

C.The significant reduction of the shame on divorce.

D.Men having more chances to know women.

答案

参考答案:A

解析: 细节题型。 根据第四段第三句This reflects the increasing equality of women and men in terms of economic advantage and the recognition that many women no longer depend on men for their survival.可知B和c项都是A项而导致的,D项在文章中没提到。因而A项正确。

问答题

背景资料: 某中型水闸工程施工招标文件按《水利水电工程标准施工招标文件》(2009年版)编制。已标价工程量清单自分类分项工程量清单、措施项目清单、其他项目清单、零星工作项目清单组成。其中闸底板C20混凝土是工程量清单的个子目,其单价(单位:100m³)根据《水利建筑工程预算定额》(2002年版)编制,并考虑了配料、拌制、运输、浇筑等过程中的损耗和附加费用。 事件1:A单位在投标截止时间提前交了投标文件。评标过程中,A单位发现工程量清单有算术性错误,遂以投标文件澄清方式提出修改,招标代理机构认为不妥。 事件2:招标人收到评标报告后对评标结果进行公示,A单位对评标结果提出异议。 事件3:经过评标,B单位中标。工程实施过程中,B单位认为闸底板C20混凝土强度偏低,建议将C20变更为C25。经协商后,监理人将闸底板混凝土自C20变更为C25。B单位按照变更估计原则,以现行材料价格为基础提交了新单价,监理人认为应按投标文件所附材料预算借个未计算基础提交新单价。 本工程在宴施过程中,涉及工程变更的双方往来函件包括(不限于):①变更意向书,②书面变更建议,③变更指示,④变更报价书,⑤撤销变更意向书,⑥难以实施变更的原因和依据,⑦变更实施方案等。

分别说明闸底板混凝土的单价分析中,配料、拌制、运输、浇筑等过程的损耗和附加费用应包含在哪些用量或单价中?
