From a different supplier, Nesud Co purchases $2·4 million per year of Component K at a price of $5 per component. Consumption of Component K can be assumed to be at a constant rate throughout the year. The company orders components at the start of each month in order to meet demand and the cost of placing each order is $248·44. The holding cost for Component K is $1·06 per unit per year.
The finance director of Nesud Co is concerned that approximately 1% of credit sales turn into irrecoverable debts. In addition, she has been advised that customers of the company take an average of 65 days to settle their accounts, even though Nesud Co requires settlement within 40 days.
Nesud Co finances working capital from an overdraft costing 4% per year. Assume there are 360 days in a year.
Required:
(a) Evaluate whether Nesud Co should accept the early settlement discount offered by its supplier. (4 marks)
(b) Evaluate whether Nesud Co should adopt an economic order quantity approach to ordering Component K. (6 marks)
(c) Critically discuss how Nesud Co could improve the management of its trade receivables. (10 marks)
Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something had gone wrong. Questioning and routine double checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the following warning: For all the help this computer may provide, it should not be seen as a device that can take the place of fundamental thinking and reasoning skills.
The main purpose of this passage is______.
A.to look back to the early days of computers
B.to explain what technical problems may occur with computers
C.to warn against a mentally lazy attitude towards computers
D.to discourage unnecessary investment in computers
After some years【24】, square dancing became【25】popular in cities and towns, but it【26】popular in the country. Then it became popular in the cities once again. Today in【27】parts of the United States you will find some school, club, or other group that is square dancing for fun.
A square is formed by four couples(对,双) who stand【28】the center of the square. Each couple stands on one【29】of the square, the boy on the left and the girl on the right.
The "caller" is an important part of the【30】 since he tells the dancers which steps to do. If the dancers do not know the steps, he teaches them. It【31】 time to learn to be good caller, and good callers are always in demand.
Large or small groups of people can dance at one time. Sometimes 800 or 1,000 people may be dancing at the【32】 time. Or there may be only one square of【33】 people.
Costumes(服装) are worn by some who square dance. This【34】 the dancing more colorful to watch. The costumes vary(不同) from place to place. Women often wear full skirts of various colors with pretty blouse(罩衫). Men may have colored skirts and western trousers which they wear【35】 when square dancing.

One way to represent the evolution of life is to compress the 4. 6-billion-year history of Earth into a 1-year-long film. In such a film, Earth forms as the film begins on January 1, and through all of January and February it cools and is cratered(变成坑状) and the first oceans form. But those oceans remain lifeless until sometime in March or early April, when the first living things develop. The 4-billion-year history of Precambrian (前寒武纪) evolution lasts until the film reaches mid-November, when primitive ocean life begins to evolve into complex organisms such as trilobites(三叶虫).
If we examine the land instead of the oceans, we find a lifeless waste. But once our film shows plant and animal life on the land, about November 28, evolution proceeds rapidly. Dinosaurs, for example, appear on about December 12 and vanish by Christmas Eve, as mammals (哺乳动物) and birds flourish.
Throughout the 1 -year-run of our film there are no humans, and even during the last days of the year as the mammals rise and dominate the landscape, there are no people. On the early evening of December 31, vaguely human forms move through the grasslands, and by late evening they begin making stone tools. The Stone Age lasts until about 11:45 p. m. , and the first signs of civilization, towns and cities, do not appear until 11:54 p. m. The Christian era begins only 14 seconds before the New Year, and the Declaration of Independence is signed with one second to spare.
In comparing all of Earth's geological evolution to one calendar year, the author shows
A.just how recently humanity has arrived on the scene
B.just how simple it is to understand the history of Earth
C.just how early humanity appears on planet Earth
D.just how difficult it is to understand the history of Earth

When prehistoric man arrived in new parts of the world, something strange happened to the large animals. They suddenly became extinct. Smaller species survived. The large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans.
That the seas are being overfished has been known for years. What researchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that the figures are conservative. One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since no baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now.
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the “shifting baseline.” The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
31. The extinction of large prehistoric animals is noted to suggest that ________.
[A] large animal were vulnerable to the changing environment
[B] small species survived as large animals disappeared
[C] large sea animals may face the same threat today
[D] slow-growing fish outlive fast-growing ones
I【69】about it with my friends Frank and Lesley.【70】of them【71】suggest anything, but they promised that they would ask their friends. A few days later【72】I was still in bed,【73】telephoned. "Is that Miss Jenkins?" a man' s voice asked. "I【74】your hobby is photography and I've got a job that might interest you in my clothes factory. My name is Mr. Thomson. " He seemed pleasant on the phone【75】I went to see him. I was so excited that I almost forgot【76】goodbye. "Good luck!" my mother said to me.
I arrived【77】early and when Mr. Thomson came he asked me if I【78】waiting a long time. "No, not long. " I replied. After talking to me for about twenty minutes he【79】me a job —not as a photographer,【80】a model!

In 1934 the scientist William Beebe dived 3 , 000 feet below the surface in a hollow steel ball. In 1935 Auguste Piccard dived 10, 330 feet. In 1960 his son Jean dived to a【35】of 35, 800 feet.
All these early dives were deep. But the divers could not stay down for very long. They had to【36】the surface after a few seconds. Scientists needed to stay down longer to study life below the surface.【37】, they succeeded. Cousteau, a Frenchman, was able to【38】down to a depth of【36】feet for one month and to a depth of 90 feet for a week.
Now scientists are developing even【39】equipment. With this new equipment, men can stay【40】the surface for days or【41】weeks. In 1962 Consteau【42】a research station 35 feet below the surface. Then in 1964 he set up another station on the ocean floor of the Red Sea. This was the first undersea station to operate【43】help from the surface.
Many countries are now studying undersea【44】. The Soviet Union has an undersea laboratory in the Crimean Sea. The United States has a laboratory 50 feet【45】on the ocean floor【46】the Virgin Islands. In 1970 five men lived there for two weeks. Then a【47】of five women scientists stayed in the laboratory.【48】came other teams of men. All were there to explore the ocean depths and【49】plans for the use of its resources. Scientists hope to find enough【50】, vegetable, and animal wealth there to provide food for the whole world.
