答案：B
解析：
主旨题。本文可分为三部分：主要站在历史角度讲述艾森豪威尔行政办公大楼的历史地位、重建和建筑风格以及大楼内发生过的重要历史事件，而A、C、D三项都以偏概全。故本题选B。参考译文：艾森豪威尔行政办公大楼( EEOB)矗立于白宫一侧，在美国历史和建筑史中均享有独特的地位。它由财政部建筑师阿尔弗雷.B.马利特设计，建于1871年至1888年间，旨在容纳国务院、战争部、海军部不断增加的工作人员，并被认为是法国第二帝国建筑风格的最佳建筑之一。在19世纪最后25年和20世纪最初的25年间，国务院、陆军部、海军部这三个制定和执行国家外交政策最密切相关的行政部门最先搬进了大楼。在那段时期，美国成为了世界大国。一些最重要的外交官和政治家搬进这座大楼中，从此，它成为许多历史事件发生的舞台。EEOB的历史早在其建成前就开始了。1799年至1820年间，第一间行政办公室建在白宫侧翼。一系列的火灾(包括英国人在1814年制造的火灾)以及过度拥挤的情况促成了现有的财政大楼的建设。1866年，鉴于建造财政大楼北翼的需要，国务院大楼被拆除。1869年12月，国会成立了委员会，专门为新的国务院大楼选址、制定计划及估算成本。委员会还将对陆军部和海军部的合理安排考虑其中。一些人希望在白宫另一侧建立一座希腊复兴式样的财政大楼。为表纪念，委员会选择了阿尔弗雷·B·马利特法国第二帝国风格的设计。1871年6月，三个部门都搬进了这座大楼里。整座大楼的建设历时17年。1888年建成时，EEOB是华盛顿最大的办公大楼，有近2英里(约3千米)长的黑白瓷砖走廊。几乎所有的内部细节都采用了铸铁或石膏。尽量减少木材的使用，以确保消防安全。大楼有八座巨大的花岗岩弯曲的楼梯和四千多个独立铸造的青铜栏杆，被四个天窗圆顶和两个彩色玻璃圆形大厅覆盖。1875年建成的国务院大楼南翼首先被投入使用。它包括高雅的四层图书馆(1876年建成)，外交接待室，以及拥有木雕、东方地毯和印花墙纸装饰的秘书办公室。1879年海军部迁入东翼，秘书处的办公室里有精心设计过的墙壁、天花板和镶嵌工艺的地板。许多著名的国家人物都参与了在EEOB花岗岩墙上呈现的历史事件。西奥多·罗斯福、富兰克林.D.罗斯福、威廉·霍华德·塔夫脱、德怀特.D.艾森豪威尔、林登.B.约翰逊、杰拉尔德·福特和乔治·赫伯特·沃克·布什在成为总统之前都曾在这座大楼里办公。曾有16名海军司令、21名陆军秘书和24名国务卿在这座大楼里办公。温斯顿·丘吉尔曾在这座大楼的走廊上走过，日本的特使曾在珍珠港爆炸事件后与国务卿科尔德尔·赫尔在此会面。

第8题：

2 (a) Explain the term ‘backflush accounting’ and the circumstances in which its use would be appropriate.

(6 marks)


正确答案：
(a) Backflush accounting focuses upon output of an organisation and then works backwards when allocating costs between cost
of goods sold and inventories. It can be argued that backflush accounting simplifies costing since it ignores both labour
variances and work-in-progress. Whilst in a perfect just-in-time environment there would be no work-in-progress at all, there
will in practice be a small amount of work-in-progress in the system at any point in time. This amount, however, is likely to
be negligible in quantity and therefore not significant in terms of value. Thus, a backflush accounting system simplifies the
accounting records by avoiding the need to follow the movement of materials and work-in-progress through the manufacturing
process within the organisation.
The backflush accounting system is likely to involve the maintenance of a raw materials and work-in–progress account
together with a finished goods account. The use of standard costs and variances is likely to be incorporated into the
accounting entries. Transfers from raw materials and work-in-progress account to finished goods (or cost of sales) will probably
be made at standard cost. The difference between the actual inputs and the standard charges from the raw materials and
work-in-progress account will be recorded as a residual variance, which will be recorded in the profit and loss account. Thus,
it is essential that standard costs are a good surrogate for actual costs if large variances are to be avoided. Backflush
accounting is ideally suited to a just-in-time philosophy and is employed where the overall cycle time is relatively short and
inventory levels are low. Naturally, management will still be eager to ascertain the cause of any variances that arise from the
inefficient usage of materials, labour and overhead. However investigations are far more likely to be undertaken using nonfinancial
performance indicators as opposed to detailed cost variances.
