Lily Window Glass Co (Lily) is a glass manufacturer, which operates from a large production facility, where it undertakes continuous production 24 hours a day, seven days a week. Also on this site are two warehouses, where the company’s raw materials and finished goods are stored. Lily’s year end is 31 December.
Lily is finalising the arrangements for the year-end inventory count, which is to be undertaken on 31 December 2012. The finished windows are stored within 20 aisles of the first warehouse. The second warehouse is for large piles of raw materials, such as sand, used in the manufacture of glass. The following arrangements have been made for the inventory count:
The warehouse manager will supervise the count as he is most familiar with the inventory. There will be ten teams of counters and each team will contain two members of staff, one from the finance and one from the manufacturing department. None of the warehouse staff, other than the manager, will be involved in the count.
Each team will count an aisle of finished goods by counting up and then down each aisle. As this process is systematic, it is not felt that the team will need to flag areas once counted. Once the team has finished counting an aisle, they will hand in their sheets and be given a set for another aisle of the warehouse. In addition to the above, to assist with the inventory counting, there will be two teams of counters from the internal audit department and they will perform. inventory counts.
The count sheets are sequentially numbered, and the product codes and descriptions are printed on them but no quantities. If the counters identify any inventory which is not on their sheets, then they are to enter the item on a separate sheet, which is not numbered. Once all counting is complete, the sequence of the sheets is checked and any additional sheets are also handed in at this stage. All sheets are completed in ink.
Any damaged goods identified by the counters will be too heavy to move to a central location, hence they are to be left where they are but the counter is to make a note on the inventory sheets detailing the level of damage.
As Lily undertakes continuous production, there will continue to be movements of raw materials and finished goods in and out of the warehouse during the count. These will be kept to a minimum where possible.
The level of work-in-progress in the manufacturing plant is to be assessed by the warehouse manager. It is likely that this will be an immaterial balance. In addition, the raw materials quantities are to be approximated by measuring the height and width of the raw material piles. In the past this task has been undertaken by a specialist; however, the warehouse manager feels confident that he can perform. this task.
Required:
(a) For the inventory count arrangements of Lily Window Glass Co:
(i) Identify and explain SIX deficiencies; and
(ii) Provide a recommendation to address each deficiency.
The total marks will be split equally between each part (12 marks)

First of all, successful language learners are independent learners. They do not depend on the book or the teacher. They discover their own way to learn the language. Instead of waiting for the teacher to explain, they try to find the patterns and the rules for themselves. They try to learn from their mistakes.
Successful language learning is active learning. Therefore, they do not wait for a chance to use the language. Instead they look for such a chance. They will try anything to communicate. They are not afraid to repeat what they hear and to say strange things. They are willing to make mistakes and try again. When communication is difficult, they can accept information that is inexact or incomplete. It is more important for them to learn to think in the language than to know the meaning of every word.
Finally, successful language learners are learners with a purpose. They want to learn the language because they are interested in the language and the people who speak it. It is necessary for them to learn language in order to communicate with these people and to learn from them. They find it easy to practise using the language regularly because they want to learn it.
The best learners of languages _____ .
A．are the most intelligent students in the class
B．are the best at memorizing long vocabulary lists
C．have the best language learning techniques
D．are the best at mastering rules of grammar
SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文： Picture the most beautiful face you have ever seen. Then ask yourself what it is about that face that makes it so lovely. That question may be difficult to answer. After all, beauty is in the eye of the beholder. But is it possible to explain the beauty of a human face using math？
According to many scholars throughout history, the answer could be yes. Most very attractive faces have proportions consistent with what is known as the "golden ratio." This ratio can best be understood by thinking of it as a rectangle. In a golden rectangle, the long side is 1.618 times longer than the short side. Therefore, the value of the golden ratio is equal to 1.618. The proportions of the golden rectangle are thought to reflect perfect symmetry. If we frame. a gorgeous face inside of a golden rectangle, the dimensions of each will correspond perfectly. The face is beautiful because it is symmetrical.
Amazingly, the golden ratio is found in many manifestations of beauty—not just in beautiful faces. The dimensions of the Great Pyramid of Giza in Egypt conform. to the golden ratio. And the famous Greek Parthenon contains many golden rectangles. Moreover, the famous fifteenth-century Italian artist, Leonardo da Vinci, deliberately used the golden ratio in his paintings. Not surprisingly, the face of da Vinci's Mona Lisa matches the golden rectangle.
What's the characteristic of most attractive faces？
A．There is no answer.
B．Beauty is in the eye of the beholder.
C．Most of attractive faces look like Mona Lisa.
D．Most attractive faces have golden ratio.
Heat Co is now trying to ascertain the best pricing policy that they should adopt for the Energy Buster’s launch onto the market. Demand is very responsive to price changes and research has established that, for every $15 increase in price, demand would be expected to fall by 1,000 units. If the company set the price at $735, only 1,000 units would be demanded.
The costs of producing each air conditioning unit are as follows:
Note
The first air conditioning unit took 1·5 hours to make and labour cost $8 per hour. A 95% learning curve exists, in relation to production of the unit, although the learning curve is expected to finish after making 100 units. Heat Co’s management have said that any pricing decisions about the Energy Buster should be based on the time it takes to make the 100th unit of the product. You have been told that the learning co-efficient, b = –0·0740005.
All other costs are expected to remain the same up to the maximum demand levels.
Required:
(a) (i) Establish the demand function (equation) for air conditioning units; (3 marks)
(ii) Calculate the marginal cost for each air conditioning unit after adjusting the labour cost as required by the note above; (6 marks)
(iii) Equate marginal cost and marginal revenue in order to calculate the optimum price and quantity. (3 marks)
(b) Explain what is meant by a ‘penetration pricing’ strategy and a ‘market skimming’ strategy and discuss whether either strategy might be suitable for Heat Co when launching the Energy Buster. (8 marks)
下列报道摘自《美元坚挺的惊讶》(Dollar's Strength a Surprise)，《纽约时报》，p.D1，1989-08-07：
“但是，现在有一种观点认为，经济正在朝”软着陆“的方向行进，经济增长明显放慢，通货膨胀率降低，但经济衰退并没有发生。
这种前景对美元的坚挺是有利的。原因有二：第一，软着陆不像衰退那样具有破坏性，因此，支撑美元的外国投资很可能持续下去：
第二，软着陆不会迫使美联储为刺激增长而降低利率。利率下降会对美元产生贬值的压力，这是因为，利率下降会使美元证券对外国人的吸引力下降，诱使人们抛出美元。此外。由软着陆预期而产生的乐观因素甚至可以抵消一些由利率下降带给美元的贬值压力。”
a．试用本章所学的汇率决定模型解释报道的第三段。
b．还有什么汇率决定因素有助于解释第二段？
The following report appeared in the New York Times on August 7,1989(“Dollar's Strength a Surprise，”p.DI)：
But now the sentiment is that the economy is heading for a“soft landing”with the economy slowing significantly and inflation subsiding，but without a recession．
This outlook is good for the dollar for two reasons．A soft landing is not as disruptive as a recession，so the foreign investments that support the dollar are more likely to continue．
Also，a soft landing would not force the Federal Reserve to push interest rates sharply lower to stimulate growth．Falling interest rates can put downward pressure on the dollar because they make investments in dollar-denominated securities less attractive to foreigners，prompting the selling of dollars．In addition，the optimism sparked by the expectation of a soft landing can even offset some of the pressure on the dollar from lower interest rates．
a．Show how you would interpret the third paragraph of this report using this chapter's model of exchange rate determination．
b．What additional factors in exchange rate determination might help you explain the second paragraph？
Explain why none of the lanthanoid sesquioxides, Ln2O3, is as acidic as Al2O3
