[背景资料]

某投资公司建造一幢办公楼，采用公开招标方式选择施工单位。招标文件要求:提交投标文件和投标保证金的截止时间为2008年5月30日。该投资公司于2008年3月6日发出招标公告，共有5家建筑施工单位参加了投标。第5家施工单位于2008年6月2日提交了投标保证金。开标会于2008年6月3日由该省建委主持。第4家施工单位在开标前向投资公司要求撤回投标文件和退还投标保证金。经过综合评选，最终确定第2家施工单位中标。投资公司总(甲方)与中标单位(乙方)双方按规定签订了施工承包合同，合同约定开工日期为2008年8月16日。工程开工后发生了如下几项事件。

事件一:因拆迁工作拖延，甲方于2008年8月18日才向乙方提供施工场地，导致乙方A、B两项工作延误了2d，并分别造成人工窝工6个和8个工日；但乙方C项工作未受影响。

事件二:乙方与机械设备租赁商约定，D项工作施工用的某机械应于2008年8月28日进场，但因出租方原因推迟到当月29日才进场，造成D工作延误1d和人工窝工7个工日。

事件三:因甲方设计变更，乙方在E项工作施工时，导致人工增加14个工日，相关费用增加了1.5万元，并使施工时间增加了2d。

事件四:在F项工作施工时，因甲方供材出现质量缺陷，乙方施工增加用工6个工日，其他费用1000元，并使H项工作时间延长1d，人工窝工24个工日。

上述事件中，A、D、H三项工作均为关键工作，没有机动时间，其余工作均有足够的机动时间。

合同约定人工费标准为30元／工日，应由甲方给予补偿的窝工人工费标准为18元／工日；施工管理费、利润等均不予以补偿。在该工程中，乙方可得到的合理费用索赔有哪几项？费用索赔额是多少？

Questions 26-45


·Read the following passage and decide which answer bestfits each space.
·For questions 26-45, mark one letter A, B, C or D on the Answer Sheet.
The "standard of living" of any country means the (26) person’s share of the goods and services which the country produces. A country’s standard of living, therefore depends (27) and foremost on its capacity to produce wealth. "Wealth" in this (28) is not money, for we do not live on money (29) on things that money can buy: "goods" such as food and clothing, and "services" such as (30) and "entertainment".
A country’s capacity to produce wealth depends upon many factors, most of which have an effect (31) one another. Wealth depends (32) a great extent upon a country’s natural resources. Some regions of the world are well supplied with coal and minerals, and have a (33) soil and a favorable climate; other regions (34) none of them.
Next to natural resources (35) the ability to turn them to use. China is perhaps as well off as the USA in natural resources, but suffered for many years from (36) and external wars, and for this and other reasons was incapable (37) her resources. Sound and (38) political conditions, and freedom from foreign invasion, enable a country to develop its natural resources peacefully and steadily, and to produce more wealth than another country (39) well served by nature but less well ordered.
A country’s standard of living does not only depend upon the wealth that is produced and (40) within its own borders, but also upon what is indirectly produced through international trade. For example, Britain’s wealth in foodstuffs and other agricultural products would be much (41) if she had to depend only on those grown at home. Trade makes it possible for her surplus manufactured goods to be traded abroad for the agricultural products that would (42) be lacking. A country’s wealth is, therefore, much (43) by its manufacturing capacity, (44) that other countries can be found ready to (45) its manufactures.

A．less

B．little

C．equally

D．few
