Passage2         Questions 6 to 10 are based on the following passage.         Salt is as necessary to life as water. In many areas of Africa people once drank the urine（尿）of animals because they had no other source of salt. Without salt, human beings die.          The human body demands that the amount of salt in the blood always stay the same. When the body does not get enough salt, it protects itself by letting less salt leave the body in. urine and sweat. But it cannot reduce this output to zero. Some salt is always escaping. On a completely saltless diet, like that of some people in Africa, the body steadily loses small amounts of salt through the kidneys（肾） and sweat glands(腺). It then tries to adjust to this loss by speeding up its secretion(分泌) of water. (78) In this way, the body attempts to keep the amount of salt in the blood at the necessary level. The result is a slow drying up of body and, finally, death. The person dies of thirst.      In cases where there is little or no water to drink, the body tries to do the opposite thing.Again, it must keep the salt level in the blood constant. Because it has little water, it attempts to stop water from leaving the body and to increase its secretion of. salt. But, as with the escaping salt, it cannot be completely successful. Some water still leaves and the person eventually dies of thirst. In short, the body's normal needs for salt and for water are both parts of the same important need to keep the salt level in the blood constant.6 Some African people once drank animal urine______.
A

when they were going to die

B

because they were thirsty

C

because there was little salt

第6题：

(c) Critically discuss the adoption of activity-based management (ABM) in companies such as TOC. (6 marks)


正确答案：
(c) Activity-based management (ABM) is a method of identifying and evaluating activities that a business performs using
activity-based costing to carry out a value chain analysis or a re-engineering initiative to improve strategic and operational
decisions in an organisation. Activity-based costing establishes relationships between overhead costs and activities so that
overhead costs can be more precisely allocated to products, services, or customer segments. Activity-based management
focuses on managing activities to reduce costs and improve customer value.
Kaplan and Cooper (1998) divide ABM into operational ABM and strategic ABM:
Operational ABM is about ‘doing things right’, using ABC information to improve efficiency. Those activities which add value
to the product can be identified and improved. Activities that don’t add value are the ones that need to be reduced to cut costs
without reducing product value.
Strategic ABM is about ‘doing the right things’, using ABC information to decide which products to develop and which
activities to use. This can also be used for customer profitability analysis, identifying which customers are the most profitable
and focusing on them more.
A risk with ABM is that some activities have an implicit value, not necessarily reflected in a financial value added to any
product. For instance a particularly pleasant workplace can help attract and retain the best staff, but may not be identified as
adding value in operational ABM. A customer that represents a loss based on committed activities, but that opens up leads
in a new market, may be identified as a low value customer by a strategic ABM process.
ABM can give middle managers an understanding of costs to other teams to help them make decisions that benefit the whole
organisation, not just their activities’ bottom line.
