You are an audit supervisor of Pluto & Co and are currently planning the audit of your client, Venus Magnets Co (Venus) which manufactures decorative magnets. Its year end is 31 December 2015 and the forecast profit before tax is $9·6 million.
During the year, the directors reviewed the useful lives and depreciation rates of all classes of plant and machinery. This resulted in an overall increase in the asset lives and a reduction in the depreciation charge for the year.
Inventory is held in five warehouses and on 28 and 29 December a full inventory count will be held with adjustments for movements to the year end. This is due to a lack of available staff on 31 December. In October, there was a fire in one of the warehouses; inventory of $0·9 million was damaged and this has been written down to its scrap value of $0·2 million. An insurance claim has been submitted for the difference of $0·7 million. Venus is still waiting to hear from the insurance company with regards to this claim, but has included the insurance proceeds within the statement of profit or loss and the statement of financial position.
The finance director has informed the audit manager that the October and November bank reconciliations each contained unreconciled differences; however, he considers the overall differences involved to be immaterial.
A directors’ bonus scheme was introduced during the year which is based on achieving a target profit before tax. In order to finalise the bonus figures, the finance director of Venus would like the audit to commence earlier so that the final results are available earlier this year.
Required:
Describe FIVE audit risks, and explain the auditor’s response to each risk, in planning the audit of Venus Magnets Co.

Millions of stars are traveling about in space. A few form. groups which journey together, but most of them travel alone. And they travel through a universe so large that one star seldom comes near to another.
We believe, however, that some two thousand million years ago, another star wandering through space, happened to come near our sun. Just as the sun and the moon raise tides on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; a large tidal wave' must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance (动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets (行星).
Millions of stars are______.
A.following a regular path in space
B.always travelling together
C.seldom wandering about in the universe
D.moving about without a fixed course

You know what a hotel is, of course. And perhaps, you also know what a condo is-aresidntial(居住的)building divided into seprate uniots that are owned by different people.What you may not know is that in someU.S. cities, the two have come together into somethingcalled a “condo hotel”.
Some condo hotels can now be found in beach and mountain towns and a few small cities,However, none is more famous than the great 105-year-old Plaza Hotel in New York,on Fifth Avenue across from Central Park. The Plaza closed for repair in When it reopened two years later,more than half of it had been changed into one of these modern condo hotels.
Here&39;s how it works: You buy what equals to an apartment(公寓). If it&39;s at&39;The Plaza,it will cost you between $ 1.5million and $9 mllion. So you own a part of the building. But there&39;s some inconvinience. You may stay there no more than 120 days a year. hereion. The rest of the time,the hotel&39;s workers can book guests into your place, just as they would in the regular hotel&39;s rooms. So if you&39;re lucky and rich,you can now live in really special quarters up to almost one thid of the year. While others pay off your mortgage(房贷)the rest of the year.
So far,a great monry of the nation&39;s condo hotel units have been purchased not by rich people but richer companiesm, including foreign ones. They want a nice place for their bosses to stay when they are in town or working late at the office.
47.A condo is a place where people .

听力原文:The spread of malaria is like a two-way street. The disease is spread to humans through the bite of mosquitoes infected with malaria parasites, the most dangerous of these being plasmodium falciparum. Uninfected mosquitoes become infected with the parasite by biting infected animals. In sub-Saharan Africa and parts of Asia an estimated 300 million people are infected every year, more than one million of them are children, many of whom die. Years of attempting to cure the disease with antibiotics and quinine drugs have caused the parasite to become resistant to treatment. Scientists are trying to come up with novel strategies for conquering malaria.One idea that has been around for a number of years is the creation of genetically altered mosquitoes that could be released into the environment.
What lead to the resistance to treatment of the parasite?
A.The use of antibiotics.
B.People's negligence.
C.The wrong way of using drugs.
D.The treatment with antibiotics and quinine drugs.

Questions 6 to 10 are based on the following passage There are many older people in the world and there will be many more. A little-known fact is that over 60 percent of the older people live in developing countries. According to the World Health Organization, by 2020 there will be 1 billion, with over 700 million living in developing countries.
It is a surprising fact that the population ageing is particularly rapid in developing countries. For example, it took France 115 years for the proportion of older people to double from 7 percent to 14 percent. It is estimated to take China a mere 27 years to achieve this same increase.
What are the implications of these increased numbers of older folk? (76) One of the biggest worries for governments is that the longer people live, the more likelihood there is for diseases and for disability(残疾). Attention is being paid to the need to keep people as healthy as possible, including during old age, to lessen the financial burden on the state.
(77)Another significant problem is the need for the younger generations to understand and value the older people in their society. In some African countries, certainly in Asia, older people are respected and regarded as the ones with special knowledge. Yet traditions are fading away daily, which does not ensure the continued high regard of older people. As society changes, attitudes will change.
Much needs to be done to get rid of age discrimination(歧视)in employment. Life-long learning programs need to be provided to enable older people to be active members in a country's development.
Social security policies need to be established to provide adequate income protection for older people. Both public and private schemes are vital in order to build a suitable safety net.
第6题:The proportion of older people________.
A. is bigger in developed countries than in developing countries B. is one-seventh of the population in developing countries C. will increase much faster in China than in France D. will be sixty percent in developing countries by 2020

The founders of the Chicago school of sociology, Robert Park and Ernest Burgess, attempted to develop a dynamic model of the city, one that would account not only for the expansion of cities in terms of population and territory but also for the patterns of settlement and land use within cities. They identified several factors that influence the physical form. of cities. As Park stated, among them are "transportation and communication, tramways and telephones, newspapers and advertising, steel construction and elevators—all things, in fact, which tend to bring about at once a greater mobility and a greater concentration of the urban populations."
Paragraph 3 indicates that all of the following are true of "natural areas" as conceived by Park and Burgess EXCEPT:
A.Use of the land in natural areas follows a consistent pattern but is generally unplanned.
B.People living in natural areas tend to have much in common.
C.Natural areas are usually protected from "invasion" by people in other areas.
D.Natural areas are an important basic component of the model Park and Burgess developed.
